This equipment is to be used at the Municipal Airport, for the purpose of weed abatement, fire control/suppression and miscellaneous airport ground maintenance. The Street Department mower is too massive to mow many sections of the airport including around the taxi lights. Staff would use a push mower for days in the past to cover these areas. Bids were sent to six different companies. Three responses were received. Rainbow Agricultural Service was the low bid at $10,906.46, which includes tax and freight costs. They offered a John Deere 2305. Please note: this equipment is not subject to the proposed emission standards for end-use off- road diesel fueled fleets, as it has a 24 horse power motor. Below is a recap of the bid responses: Rainbow Agricultural Services: $10,906.46 Lampson Tractor: $12,209.15 Noble Tractor: $13,890.05 Staff recommends awarding the purchase of the tractor/mower to Rainbow Agricultural Service in the amount of $10,906.46. Funding for this equipment was approved in the Fiscal Year 07/08 budget in account number 600.5001.800.000 in the amount of $10,000.00. Staff is requesting a budget amendment transferring $910.00 from account number 600.305.000 for the difference in cost. RECOMMENDED ACTION: Award purchase of one new four wheel drive diesel tractor/mower to Rainbow Agricultural Service in the amount of $10,906.46 and authorize a budget amendment in the amount of $910.00.

As presented and approved by Council during the Supplemental Law Enforcement Service Fund -COPS Grant public meeting held November 15~ of 2006 (Attachment 1), staff desires to deploy Mobile Computer Terminals for emergency response vehicles. It is estimated that MCT's in emergency response vehicles reduce radio communication demands between field units and dispatch by up to 50%. MCT's rely on a wireless computer network, which enables a user to send and receive dispatch calls, access a variety of computer databases, communicate with other emergency responders and provide immediate status updates to their departments via laptop computers, instead of passing this information through a dispatch center via radio communications. As part of this project, staff submitted Requests for Proposals to vendors in July of 2007, according to Mobile Computer Terminal Specifications for public safety vehicles desired by the City of Ukiah. Bids were opened September 17th, with 2 responses. Williams USA (lowest overall bid) met the specifications provided for in the RFP, at a total cost of $80,334.00, including sales tax. Continued on paoe 2 RECOMMENDED ACTION: 1. Authorize the purchase of Mobile Computer Terminal equipment from Williams USA, in an amount not to exceed, $80,334.00 and authorize budget amendment transferring $66,945.00 from Fund 205 Fund Balance to account number 205.2001.800.000.

This bill yearly appropriates monies for use in augmenting law enforcement agencies. Originally this bill contained a sunset clause, which was removed in 2001, prior to the last state budget crisis. Because of the state budget crisis, and the impacts to local and county government, this funding has remained in question in the state budget since that time. This money was originally granted to law enforcement agencies from the State of California's surplus funds. Other grant funding developed while the state experienced a large surplus (CLEEP, CLETEP) similar to these SLESF funds has already been cut from the state budget. Continued on oage 2 RECOMMENDED ACTION: 1. Hold Public Hearing for the COPS Grant FY 2006/07; 2. Authorize departmental spending plan for FY 2006/2007 SLESF Grant.

In the past, council has authorized these funds for the purchase of records management software, computers, digital cameras, used detective vehicles, portable alcohol testing units, hostage crisis equipment, summer intern assistance, equipment for our evidence facility, evidence facility improvements, use-of-force training equipment, front officer records clerk assistance, dispatch personnel, and evidence property custodian personnel. During FY 06/07, the department will receive $100,000 dollars in SLESF grant funds. This money, as outlined in Government Code Section 30061 - 30065, must be used exclusively in the support of front line police services. As noted in the government code; 1. These moneys shall supplement existing services, and shall not supplant any existing funding for law enforcement services provided by that entity. 2. A public hearing is required. 3. A yearly report will be filed with the Supplemental Law Enforcement Oversight Committee. 4. Funds received shall be expended or encumbered no later than June 30 of the following fiscal year, and agencies that do not meet this requirement shall remit unspent SLESF moneys to the state. Departmental Spending Plan 2004/2005 Funding: For this funding, staff recommends three purpose areas. 1. Part-Time Evidence & Property Custodian 2. Part-Time Dispatch Assistance 3. Transcription Services 4. In Car -Mobile Computer Terminals Part-Time Evidence and Property Custodian Historically, the department has employed apart-time evidence and property custodian to manage the department evidence related functions. When the department moved from our old evidence facility to the new evidence facility a Police Sergeant was reassigned to oversee and manage the move into the new evidence facility. This reassignment was required to oversee an evidence room audit, and the department's bar coding and evidence management software system upgrade. Prior to his retirement, the Police Sergeant completed the transition to the new facility and in FY 05/06 the department hired a grant funded part-time evidence and property custodian to manage the department's evidence related functions. This current part-time grant funded position will work approximately 20 hours per week this fiscal year, managing the department's evidence functions. This position was discussed during the FY06/07 budget hearings and is currently included within the current FY06/07 City of Ukiah, Supplemental Law Enforcement Service Funding budget. PUBt.IC HEARING REGARDING NOTIFICATION OF AWARD OF SUPPLEMENTAL LAW ENFORCEMENT SERVICES FUND, CITIZENS OPTION FOR PUBLIC SAFETY (COPS) GRANT IN THE AMOUNT OF $100,000 FY 06/07. Part-Time Dispatch Assistance During the last fiscal year, the department experienced along-term employee absence within the dispatch center. To assist with shift coverage, vacations and other employee shortages, the department began the use of part-time dispatch assistance. This assistance has been provided for by dispatchers from other agencies and our cadet program. This assistance has proven to be highly effective in helping to cover for training, vacation, and other shortages within the dispatch center. This current part-time grant funded position will work on a "limited as needed basis" this fiscal year, providing shift coverage within the dispatch center. This position was discussed during the FY06/07 budget hearings and is currently included within the current FY06/07 City of Ukiah, Supplemental Law Enforcement Service Funding budget. Transcription Services Funding for our transcription services had for a number of years been received from a Federal Block Grant program. Funding in this Federal program was discontinued in August of 2005. Since that time, funding for this service has been provided through this grant program. Our transcriptions services program is a highly successful and critical program for the department. This program has proven to be highly effective in reducing officer report preparation time, and increase officer availability. This position was discussed during the FY06/07 budget hearings and is currently included within the current FY06/07 City of Ukiah budget. In Car -Mobile Computer Terminals In August of 2004, department staff presented an overview of the department's staffing and workload levels to the City Council. One of the most significant issues of concern during this presentation was the steadily increasing number of calls from our community for police services. In 1990, the department responded to a call for police services an average of 34 times a day, in 2000 that number had increased to 56 times a day, in 2003 an average of 59 times a day, and by August of 2006 that number has increased to over 80 calls for police services per day, or an average of 13.3 investigations by each patrol officer per day. These calls for police services have reduced patrol officers ability to conduct proactive, self-initiated activity., and crime preventative measures. As would be expected, as our calls for service have increased, so have the number of criminal arrests the department has made. In 2000 the department made 1,747 misdemeanor and felony arrests, and by 2003 this number had increased to 2,232 arrests, an average of 6.1 arrests per day. In the first 8 months of 2006, the department has 3 PUBLIC HEARING REGARDING NOTIFICATION OF AWARD OF SUPPLEMENTAL LAW ENFORCEMENT SERVICES FUND, CITIZENS OPTION FOR PUBLIC SAFETY (COPS) GRANT IN THE AMOUNT OF $100,000 FY 06/07. reached 2003's total numbers; increasing this average to 9.1 arrests per day. In part, because of these increasing demands for police services on the department, Sales Tax Measure S was approved, and 5 additional officers have been authorized for the department. As the new officers are hired and trained, four new officers will be assigned to respond to these increasing calls for service, and one officer will be designated to specifically enforce traffic related issues. While these officers will significantly improve the department's ability to respond to calls for police assistance, their addition, and the increasing number of police service calls have placed a significant burden on our dispatch personnel. Our dispatch staff supports all police, fire and ambulance services within the City of Ukiah. A dispatcher answers an emergency designated telephone line over 178 times per day, and these numbers continues to increase. Adding our non-emergency telephone lines and radio traffic from police, fire and ambulance personnel, along with requests for dispatch assistance, coordinating responses, and performing numerous criminal warrant, DMV and DOJ computer inquiries; police, fire and ambulance workload has overburdened the dispatch staff. Since 1996, six dispatch personnel have been authorized within the department. These six dispatchers typically work a modified 40 hour work schedule, which allows the department to staff the dispatch center with a single dispatcher from midnight to 1 PM and two dispatchers from 1 PM until midnight. During vacations, sick and extended leave shortages, the department can only staff a single dispatcher on-duty, whose shift is modified to a 12-hour schedule to accommodate the staffing shortage. To reduce dispatch workload, staff has been researching the deployment of Mobile Computer Terminals (MCT's) for emergency response vehicles. It is estimated that MCT's in emergency response vehicles reduce radio communication demands between field units and dispatch by up to 50%. MCT's rely on a wireless computer network, which enables a user to send and receive dispatch calls, access a variety of computer databases, communicate with other emergency responders and provide immediate status updates to their departments via laptop computers, instead of passing this information through a dispatch center via radio communications. These functions reduce dispatcher workload, by allowing in-field users direct access to information needed, and free dispatch personnel to focus on collecting additional information from an emergency caller, or turning their attention towards other emergency calls being received by the dispatch center. Although MCT's were originally designed for use within the Public Safety arena, their use has also extended to other areas. These systems can be expanded to include dispatching and information requests for Public Works, Parks, Electric, Water, and Utility service calls. 4 PUBLIC HEARING REGARDING NOTIFICATION OF AWARD OF SUPPLEMENTAL LAW ENFORCEMENT SERVICES FUND, CITIZENS OPTION FOR PUBLIC SAFETY (COPS) GRANT IN THE AMOUNT OF $100,000 FY 06/07. Trouble tickets, requests for service, billing and response information can be generated or collected by responding field personnel, reducing support staff workload. Over the last 5 months, the Police Department and the City of Ukiah IT Department have worked closely together to develop an implementation plan for the deployment of MCT's. Staff has met with both vendors and consultants to develop a comprehensive plan which will support both the initial deployment of MCT's and allow for the future deployment of MCT's for other departments within the City. Before MCT's can be deployed, an upgrade to our server system and network is required to meet strict California Department of Justice standards. Once these upgrades are in place, the Police Department plans an initial deployment of 11 MCT units for in-field units, and allow other departments, Fire, Public Works, Electric, Utilities and Community Services to be added in the future. The first year cost of this project is estimated to be $175,500 dollars, which would be funded by the SLESF Grant and the department's asset forfeiture accounts. These costs include $75,941.12 dollars in software costs, $64.959.87 in vehicle hardware costs, $11,037.91 in State of California Department of Justice set-up costs, and $23,476.57 on- going yearly maintenance costs. The on-going costs reflect the use of cellular data networks and dedicated frame relay phone lines to the Department of Justice to support the initial deployment of MCT's in the field. Other common wireless technologies exist, that could significantly reduce these on-going costs in the future, but are significantly more expensive to initially deploy. The IT Department is currently continuing to research the future deployment of wireless systems to support the City of Ukiah. Initial funding for this project will be provided by the projected revenue and the current balance of the Supplemental Law Enforcement Service Fund, with the remainder being provided by department's asset forfeiture accounts.

Candace Horsley, City Ma pager Table 1.1 outlines the replacement schedule details. All three vehicles scheduled for replacement were surplus from other City Departments and have served an extended period for the Parks and General Government Buildings Divisions. Given the age of the vehicles, mileage and deteriorating conditions, the vehicles were recommended for replacement. In the case of the Parks Division flat bed with dump body, the vehicle will be transferred to the Golf Division and a five yard dump truck will be sent to surplus. The transference of this vehicle will serve the limited mileage use of the Golf Course and will allow for the disposal of a larger, older and less fuel efficient vehicle. The City's Purchasing Division sent requests for bids out to all qualified vendors on file which included twenty dealerships. Ukiah Ford was the overall low bidder at $51,483.75 for the two (2) new 2007/2008 one ton trucks with service bodies and Holder Ford of Lakeport was the overall low bidder at $28,341.75 for the new 2008 flat bed truck with dump option. Refer to the attached bid summary tables for a complete listing of responses and bid amounts. The funding in the amount of $60,000 (100.6001.800.000) for the Parks Division and $35,000 for the General Government Division was approved in the Fiscal Year 07/08 budget.

(Attachments 2, 3 and 4, respectively.) As previously indicated, the City Council is required to update its UWMP every five years. Prior to adopting the update, the City Council must provide prior published notice, provide direct notice to Mendocino County, and conduct a public hearing on the plan. The public notice has been published and Mendocino County has been notified all as required by law and the matter is on the agenda to conduct the public hearing and consider the adoption of the plan. The prior ASRs discuss the legal requirements for the UWMP and discuss certain aspects of the plan. Notice was sent to numerous public agencies and other interested parties on August 15, 2007, requesting comments on the plan. (See Attachment 3 and RECOMMENDED ACTION: Conduct a public hearing and adopt the resolution (Attachment 5) adopting the revised update to the City's Urban Water Management Plan. ALTERNATIVE COUNCIL POLICY OPTIONS: Open the public hearing, receive public comment, and continue the hearing to provide additional information or revisions prior to acting on the plan. Citizens Advised: N/A Requested by: City Attorney Prepared by: David J. Rapport, City Attorney Coordinated with: Candace Horsley, City Manager, Tim Banyai, Brown and Caldwell, Robert C. Wagner, Wagner and Bonsignore, Gary Weatherford Attachments: 1 -Revised UWMP -October 17, 2007 2 -ASR for 8/15/07 Council mtg. 3 - ASR for 9/19/07 Council mtg. 4 - ASR for 10/3/07 Council mtg. 5 - Comment letter from LAFCO Executive Director 6 - Resolution Adopting UWMP --- Approved: + " Candace Horsley, City M ager Agenda Summary Report Page 2 October 17, 2007, City Council meeting attachment 1 thereto.) To date, the City has received amark-up of the UWMP update from a hydrologist with Sonoma County Water Agency ("SCWA") and more recently, on October 5, written comments from the Executive Director of the Local Agency Formation Commission ("LAFCO"). (See Attachment 5.) Submitted with this ASR is a revised UWMP update (Attachment 1). The changes from the previous draft are shown in underlined/strikeout format. The revisions are intended to respond to comments from Councilmember McCowen, SCWA and the LAFCO Executive Director. Some additional revisions are proposed, also shown in redlined/strikeout format. Councilmember McCowen wanted the UWMP to clearly define terms such as "percolating groundwater," "groundwater," and "underflow" and to use those terms consistently. (See revised pages ES-1, and revisions throughout the plan.) Some revisions have been included to respond to SCWA comments. (See, e.g., pp. ES- 4, ES-6, 2-1, and 2-6.) Other SCWA comments did not warrant changes to the UWMP for the reasons explained by Robert Wagner at the workshop on October 3. Those comments concerned encroachment on SCWA water rights. Mr. Wagner explained why meeting future demand from groundwater wells would not encroach on SCWA or Flood Control District rights to Lake Mendocino Project Water. Comments from the LAFCO Executive Director ("LAFCO Comments') have resulted in changes at ES-5, §2.1 on p. 2-1, §3.1.3 on p. 3-2, §3.8.1 on p. 3-11, and §3.10 on pp. 3- 28 to 3-31. In summary, in LAFCO Comment #2, the water use data included in the plan runs through 2006. (See Table 5-3, p. 5-3.) The table cited by the LAFCO Comments reports pumping from Well No. 4 through 2004. In response to LAFCO Comments #'s 6-8, regarding the sphere of influence area used in the plan and the issues surrounding future annexations, the plan at ES-5 describes in more detail the current status of the City's sphere of influence and explains the reasons for basing future water use projections on serving the area described in the plan. This is the largest area the City is likely to serve over the next 20 years. For water planning purposes, it is appropriate to consider that potential demand. The revisions to the UWMP recognize that the City's sphere of influence may be smaller than this and that the City, for various reasons, may not serve water to that entire area, even if it is annexed into the City, in which event the actual demand will be less than projected in the plan. LAFCO Comment #9 is addressed by revisions on p. 3-2. The LAFCO Comment misunderstands and misapplies the "no injury rule" and the revision explains why the City's use of its permit entitlement to 20 cfs and any changes to its place of use or points of diversion would not violate that rule. At the same time, the revision to the plan acknowledges that the State Board has discretion to condition permit changes for the protection of other water users. That same section responds to comment #10, regarding the petition to extend the time to put water under the City's permit to Agenda Summary Report Page 3 October 17, 2007, City Council meeting beneficial use, citing to the Water Code provisions that give special deference to municipalities to allow them time to put water to beneficial use. LAFCO Comments 11-14, concerning (1) the DWR and USGS reports referenced in the plan's discussion of groundwater, (2) the need for a groundwater basin study, and (3) the current groundwater conditions in the Ukiah Valley, are addressed at pages 3-28 to 3-31. In summary, these additions to the plan rely on data, including water table hydrographs through 2007 from the available record of long-term monitoring of wells in Ukiah Valley, to confirm that draw down and recharge in the basin has not changed significantly over time. It points out that the DWR Bulletin was updated in 2004 and is not 25 years old as stated in the LAFCO Comments. It relies on current data to demonstrate that current sources of recharge to the groundwater aquifer are many times the projected future usage by Ukiah over the next 20 years. Reference is made to that discussion for further detail. The LAFCO Comment appears to advocate delaying the update of the UWMP, and presumably relying on the outdated update adopted in 2002, until an extensive groundwater basin study is completed. This proposed delay in complying with the City's statutory mandate is impractical and not justified. The City is required to update its plan every five years. It is legally entitled to rely on the best information available when it is preparing that update. (See, e.g., Water Code §10631(b)(4) which states: "A detailed description and analysis of the amount and location of groundwater that is projected to be pumped by the urban water supplier. The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records.") The City does not know how much the study advocated by LAFCO will cost, how long it could take, how it will be financed, how many other agencies would participate, and so on. As a long term goal such a study may be worthwhile, depending on cost and other factors. However, the information currently available, as discussed in the UWMP at 3- 28 to 3-31, does not indicate a current condition of overdraft and appears to show that the sources of recharge to the aquifer available to the City are many times the amount of water the UWMP projects the City to use. In staffs judgment, the LAFCO Comment does not warrant a delay in adopting the updated UWMP. The City Council should conduct the public hearing on the proposed plan. A resolution is included, if the City Council decides to approve the plan. (See Attachment 6.) The Council can request additional information and continue the public hearing, if it so chooses.

The U~X/MP is prepared in compliance with the Uxban Water Management Planning Act (California Water Code llivision 6, Paxt 2.6, Sections 10610 through 10657). This act requires that all urban water suppliers providing water fox municipal purposes to more than 3000 customers ox supplying more than 3000 acre-feet annually prepare an UWMP update every five years. The goal of the U~C~MP is to assure that every effort is made to provide the appropriate level of reliability in water service to meet the needs of the various customers during normal, tiro, and multiple dry ycaxs. The U\Y/MP documents the Cii}r's planning activities fox the next 25-ycaxs to ensure that this- goal is met The U~X/[s4P is submitted to the California Department of Water Resources (D~Y~R) Eor general compliance with the Uxban ~~'ater Management Planning Acr. The following sections provide a summary of this UWMP. Water System Chapters 2 and 3 of die CWMP present a description of the City's existing water supply and treatment facilities, water rights, and distribution system. Water supply is defined as the amount of water available from a source or combination of sources (e.g., streams, rivers, ponds, lakes, groundwater, etc.) Eox use by a water purveyor. Water supplies from the Russian River and its undecdow are subject to the State A$'atex Resources Control Board (S~~~RCB or State Water Board) requirements outlined in the Ciry's water right permit. ~l water right permit or license provides the legal entitlement to divert water Erom a defimed channel by a user Erom a specified source (water supply) for a beneficial, non-wasteful, use. The permit ox license spells' out the point of diversion, place of use, purpose of us-e, the amount or rate of water that can be diverted, and the time allowed for putting water diverted under die permit to beneficial use. Sources, such as percolating gxoundwatex, that are not Erom the Russian River ox its undexflow, do not require a permit or license issued by the State Water Board. In this plan references to "~roundwatex" will include both percolating gxoundwatex winch does not require an appropriadve water tifhts pernnt Erom the \x'atcr Board and gxoundwatex lowing in a definite channel_ which does rec4uixe a permit References to "percolating groundwater" will only refer to groundwater not requiting a pemtit References to "undexflow" will refer to groundwater flowing in a definite channel drat does requite a cp rmrt. Just as a water right permit or hcense restricts the amoun[ of water available Eor use, pumping and treaament capacity can also limit the amount of water that can be diverted from a water supply. Pumping capacity is the amount of water the City can physically divert using its diversion works (wells, pumps, storage tanks, etc.) under its water right permit or from non-permitted sources such as percolating groundwater or water subject to pre-1914 water rights The pumping capacity is dependent on the pump flow rating and aquifer ~°ield. The water treatment and its capacity axe regulated by the strict requirements of the California Department of Health Services (DHS). Water Supply. 'I'hc Cit}' obtains its water supply Exom the underdow of the Russian River (surface water) and one pexcolating_groundwaterwcll. The pumping sources fox the distribution system consist of a Ranne}' collector and two wells (~~Uells 3 and 5), which are considered undexflow of the Russian River and subject to ES-1 DRAFT for review purposes only. P_11280001126619-Ukiah UWMPlOraft Report-August 20071DraftUWMP(10 7 2200 71tlo Executive Summary 2005 Urban Water Management Plan the requirements of the water right permit and one percolatin~gxoundwater well (lX.'ell 4). .~"n-~a«d XX'ells 1, 2, and 6 arc no longer used by dte City. Well 1 has been out of service since the 1970'x. XGells 2 and 6 (XY7atci from Wcll 6 is-was pumped into Wcll 2) were removed from the City's latest domestic water supply permit and may no longer be used as a source of supply. Wells 2 and 6 had to be taken out of service during constmcdon of the new 1.5 million gallon dearw~ell Eor the Water'I'reatment Plant If a water supply well is removed fiom scroice fox more than a year, it must comply with current DHS standards. The cost to rehabilitate the wells to meet DHS standards, which would require installation of an annular seal and electrical upgrades make it economically infeasible to return these wells to service. The pumping capacity of Wells 2/6 is only SO gallons per minute (gpm). Even though it is not cost effective to rehabilitate Wells 2/6 Eor the City's water supply, Well 6 could be used x~s-i3in its present condition to irrigate the adjacent softball complex fields, which would reduce the potable water used fox irrigation. The Ranney collector, which provides the source of water foe the water treatment plant (XX/'IT'), has an existing pumping capacity of 3,400 gpm or 4.8 million gallons per day (mgd). "Phe available capacity of the Ranney collector is significantly less than the designed capacity of 13 mgd, which is equal to the City's water right. 'fhe maximum capacity obtained from the Ranney collector was 9 mgd, well below its design capaciri. The Ranney collector has steadily declined fiom') mgd to its current capacity of 4.8 mgd. 'Che signiEtcant loss in capacit}° of the Ranney collector may be a result of changes in the Russian River channel moving away Eiom Ranney collector and the compaction of clays and silts in the civexbed over the Ranney collector. Another concern is the Ranney can only be used approximately six months a yeti during the drier weather months. During the xaina months, the turbidity in the Russian River increases, which increases the turbidity of the water in the Ranney collec[ox. The Micxofloc contact daxificadon-filtration units Located at the WTP cannot be operated efficiently under high turbidity conditions. It is not possible to cely on the Ranney collector as a water supply source during [he winter when the turbidity of the Russian River is high. Xx'ell 3 has a pumping capacity- of 650 gpm. It is available Eox use throughout the year. Wcll 4 has a pumping capacity- of 800 gpm. I[ is available Eox use throughout the veac. XX'ell 5 has a pumping capacity of 300 gpm. We115 is located near the Ranney collector. When the Ranney collec[or and Wcll 5 axe used at the same time, the pumping capacity of Well 5 is reduced because it is within the cone of water draw down depression of the Ranney collector. Also, Well 5, like the Ranney collector, can be affected by high turbidity in the Russian River. Therefore, Well 5 is used during the winter when the Ranney collector is not used. The to[al pumping capacity of the City's water system during the dry months is approximately 4,850 gpm ox 6.98 mgd. Most of this water (3,400 gpm) is- provided by the Ranney collector. The typical peak day water demand during the drv° months is appxoximateh~ 6 mgd and the peak water demand has been as high as- 7.677 mgd (Summer 2000). If the Ranncc collector was lost, XX/ell 5 would be operated, but it only has a pumping capacitt~ of 300 gpm. 'the City does not have the redundant pumping capacity to mee[ peak demands without the Ranney collector in service During the rainy months, when the Ranney collector can not be used because of the high turbidity, the pumping capauty is approximately ],750 gpm or 2.52 mgd. The typical peak day water demand during the rainy months is 2 mgd. 'I'hc loss of any pumping capacih~ during the winter months puts [he City in a difficult position to meet peak water demands. Drought conditions also affect the pumping capacity of the water supply system, especially the surface water supplies. The City is evaluating the addition of two )~-groundwater wells to increase the water supply and provide rcliaUilin' and redundancy to the water supply system. ES-2 DR4FT far review purposes only. P112 112 1 kl h WMPoDrafi Re A u t20 TDraft UWMP 107 207 do Executive Summary 2005 Urban Water Management Plan 1'he potter Valley Project diversion from the Eel River watershed to the Russian River watershed by Pacific Gas and Rlectxical (PG&E) has recently been reduced by an estimated 26 percent to 33 percent. This diversion has been ongoing for almost 100 years wi[h agricultural, municipal, and commercial economies relying on this diversion. d preliminary analysis- was conducted to determine die effect reductions in flow would have on Lake Mendocino, the Russian River, and the City's water supply. 1'he results of the pxelitninary analysis show that sufficient water supply is available w meet the City's current and projected water demand over the next hz%enty years and that increased diversions by dte City will only have minor effects on Lakc Mendocino. '1'hc Citv is exploring opportunities with other agencies to develop a more accurate computer model to predict the impact of reduced Eel River diversions on water users. 11s new information becomes available, the UWMP should be revised as necessary. The cadre analysis fox the Eel River diversions is located at the end of Chapter 3. Water Treatment Facilities. In 1992, the City constructed a water treatment facility fox water Exom the Ranney collector '1'hc water treatment plant is regulated by the DHS. DHS promulgates regulations for public water supply systems, including primary drinking water standards. The water treatment facility has a capacity to treat up to 6 mgd. [Iowevex, because the Ranney collector s}'stem capacity is only 4.8 mgd, nc~ water treatment plant capacity is limited to 4.8 mgd. As mentioned earlier, the water treatment plant is only operated during the dry months when the turbidity is low. It is not feasible to operate the water treatment plant during periods of rainy weather when the mxbidity of water in the Russian River is high. Modifications to the water treatment Eaciliry were completed in 2006. The improvements included a 3 mgd Microfloc contact daxification-filtration unit. The purpose of the improvements was to increase xcliability and provide redundant}' at the water treatment plant. "I'he water treatment plant is designed to expand to treat another 3 mgd with the addition of a fourth Micxofloc unit. Water Rights. Under its permit (\x'atex Right Permit 12952), the Cin has the right to dn~ert 20 cubic Eeet per second (cis-), which produces a theoretical maximum of approximately 14,480 ~F of water annually, but see §3.10, page 3-18, where it is es-tnnated that at the City's permitted diversion rate of 20 cfs and a peak water use in the month of Jul}', the City would actually use approximately 8,400 ~1F annually, when it Etrst puts its full permitted entitlement [o beneficial use. rlppxosimately 2,027 ~1N of water diverted by the City is recognized by the State ~C'ater Board as a Pre-1949 ~lppxopriative Right The water rights in the Russian River below Lake Mendocino axe divided between pre- and pox[-1949 because that is the year that the California State Department of Finance filed an application to appropriate water Erom the East Poxk of the Russian River fox the Coyote Dam, Lake Mendocino Pxojecr' When the State ~X7ater Board approved the permits fox Lake Mendocino Project Water, it dcdaccd that those rights would be junior to water being used by other appropriators- on and prior to 1949. The date when an application to appropriate water is- filed with the State ~C'atex Board is important, because in a }'ear when there is not enough water to satisfy the Eull amoun[ of water authorized Eor appropriation, an earlier filing date has priori4~ over a later filing date. There is also a preference fox munidpal uses over other uses. The Litt°'s ~r'atex Right Permit has- been assigned number 12952 and has a pxioxiri date of 1954. 1?ach water rights permit issued by die State Water Board gives the pexmittee a set amount of time to actually use the water authorized fox diversion under the permit The City was originally issued the permit in 1961 and the City had 10 years to put the full amount of yvatcx to benefcial use. That time has been extended several times. The latest extension gave the City until December 31, 2000. Prior to that date, the City filed another Petition Eor Extension of Time to put the water to beneficial use. The most recent request asks to extend the time to 2015. Tha[ petition is pending before the State Water Board. The City has also petitioned the State 1'he City or its predecessor m interest has been supplying water [o i[s residents since the later 1800'x. The City has pre- 19] 4 water rights, the full extent of which has not been eonelnsively determined. E53 DRAFT for review purposes only.

The City is legall}' entitled to connnuc putting water available under the permit to beneficial us-e, pending State Water Board's action on the City's petition Eox a tune esrension. The City also has a contractual agreement with the Mendocino Count}' Russian River Flood Contro] and Water Conservation Improvement District (Flood Control District) to purchase up [0 800 AF of water annually. 'Elie blood Control District can only ternunate the contract with five years prior notice to the Cin~. Water Distribution System. The water distribution system consists of surface water well pumping, percolating groundwater well pumping, water treatment plant high scnrice pumping station, storage reservoirs, and piping to and within the water distribution system. After chlorination, surface water ~~/ells 3 and 5 axe pumped directly into the distribution system. Well 4, following chlorination, also pumps directly into the water distribution s}'stem. 1'he high service pumps are located at the water treatment plant and take stored treated water and pump it into the water distribution system. The City has eight reservoirs. The combined storage capacity of the reservoirs is 6.1 million gallons (18.7 AF). The storage provides short term treated water storage to be used on a daily basis and fox emergency situations such as Eire fighting. It is not recognized as a water suppl}' source. Water Use. Based on the average water use from 2000 through ?(3E)42006, the City uses approximately 4,A~000 AF of water annually.

Recycled Water Chapter 4 discusses recycled water opportunities for the City's Wastewater Treatment Plant (~X~V'IP). 1'he WW fP serves the Ciry of Ukiah and the Ukiah Valley Sanitation District. The City has set a goal to develop a Water Recy ding Master Plan to investigate the economic feasibility of recycled water in the Citv and Ukiah Valley. The potential quantity oErecyded water Exom the WWTP could be 5,101 AF annually in 2030- Using all the recycled water from the W\XTI'I' would require both publicly and privatelyowned facilities. However, barriers could limit the feasibility of a xecyded water program for privately-owned facilities. Based on discussion with local farmers and thewricultural industr}yThesethe perception is drat the Eollowi~-bamers xist in the Ukiah area: 1. Seasonal needs Eox water does not necessarily correspond with times when recycled water is most available, thus requiring additional storage faciflties. 2. Fox organic farmers, the thought is that use of xec}'ded water would remove the organic certification from their products-. 3. Private water users who may believe they potentially could lose their existing water rights if they use receded water. 4. Existing water supplies appear to be sufficient to meet their needs. 5. It is not cost effective to use eecyded water without subsidizing the recccle water program. To fully implement a water recycle program, these barriers will need to be addressed through public education pro~rams- ES-4 DRAFT tee review purposes only.

Executive Summary 2005 Urban Water Management Plan Historical and Projected Water Use Chapter 5 discusses the historical and projected water use fox the City. Water demand projections provide the basis for Future water facilities. Historically, the Citv has experienced slow population growth and tins trend is expected to continue An annual population growth rate of 1 percent was assumed for the City. Based on a 1 percent population growth rate, the City will reach a buIld-out population of 17,992 in 201 ~. 'Phis corresponds to a water use of 4,592 All annually. Based on estimates provided by the City, a rough estimate of unaccounted for water (eg., water in the system that is un-metered water use such as fire protection and training, system and street flushing, sewer cleaning, construction, system leaks, unauthorized connections, and meter inaccuracies) is 138 dF (three percent unaccounted Eox water loss). Therefore, the total projected water demand within the present City limits is 4,730 AF. "1 he Cin's curxendy approved sphere of influence includes the entire Ckiah Valley from Burke Hill Road to Highway 20 to the north and south and ridge top to ridge top on the eact and west In 1995 the Cirv General County Board of Supervisors- to discuss a possible tax sharing agreement between the Citc and the Countr- These discussions produced an alternative sphere of influence which includes some areas to the north of the included the largest reduced sphere of influence which the City- mac seek appxocal Eor and assumes that it will annex land withnt that area within die nwt 20 years.

In that event. the demand for Cin~ water over the nest 20 years will be less than estnnated in this plan. However, it is pendent for planni~ numoses to make d~ese assumptions in order to determine whether the City has sufficient water to sen-e these areas and what limitation or deficiencies should be addressed-if future demand reaches this level. ' ' '1'hc population witlnn nc~ sphere of influence is expected to increase from approximately 5,67 to 12,675. 'this is an increase of 7,000. ~1t 2.86 people per connection, which is the average number of people per connection Eox the Cirv, the total number of connections fox a population of 12,675 is 4,432. The Cih~'s average water use per connection is 0.73 AI~P. Using this same average water us-e Eor the connections within the sphere of influence, the water use is 3,235 Ab~Y. Including the 3 percent unaccounted fox water loss, this value increases to 3,332 ~1FY. It should be noted that some of the connections within the City's sphere of influence arc served by other water districts.

Executive Summary 2005 Urban Water Management Plan periods is because the pumping capacity of the existing Ranney collector, surface water wells, and groundwater well is limited. The Citt° has increased storage capacity in the water distribution scstem that helps with short term emergency capacity. I lowevex, DHS does not classify the City's water storage capacity as a water supply. "Po increase the pumping capacity to provide a more reliable and redundant water supply, the City is conducting a groundwater well siring study to increase groundwater well production by 1,500 gpm. These improvements will help the City meet its peak demands. 7'he City's water righ[ includes Pre-1949 and Post-1949 water rights. 'The Yxe-1949 Appropriative water right of 2,02? dF annually is senior to Project Water (water stored in bake Mendocino, see 5233.3). This water right is recognized by the State Water Board." The Pos[-1949 Appropriative Water Right has a 1954 priority date and is senior to subsequent appropriators. Water Supply Versus Demand Comparison Chapter 6 provides a comparison of projected water supplies versus demand. It also discusses water shortage expectations. "phe water use, including the City's sphere of influence, will be approximately 8,062 A FY compared to S,~E}-400 ~1FY of water supply expected during amulti-year drought. The 8,x"&400 ~1FY of water supply is based on a ~0 percent reduction in water supply based on the City's water right. This analysis shows [hat doting severe drought conditions, the Ciry has sufficient water supply based on its water right. dlthough not likely, if the State Water Board denies rite City°'s ~ie~r etinon to extend the time to put water authorized by its permit to beneficial use, the Ciry would have to find other methods to meet water demands. "These methods could include use of recycled water, greater water consen*ation, and use of groundwater wells. Demand Management Practices Chapter 7 discusses water conscroation and demand management practices. This chapter presents a description of the City's water conservation ptogtam. Included in the discussion is an economic analysis of water conservation Demand Management Measures (DM1~4s) fox DMM 1, 2, 6, and 14. It is likely that previous and ongoing conservation measures have resulted in water saving in the range of appxoximateh~ 2 to 5 percent of total water production. The water savings already achieved by existing conservation measures will have some impact on the City's ability to Eurthex reduce demand. Nevertheless, the City anticipates achieving additional water savutgs by further implementation of DMMs in the Eumxe. Of the Eoux DMMs analyzed, only three appear [o be cost effective fox the Ciry. DMMs- 1, 2, and ]4 should be evaluated in the future to assess if the City has the capital to implement them.

INTRODUCTION This- chapter provides an overview of the Urban Water Management Plan (UWMP), discussion of previous reports, the City's policy on public participation, and cooxdinafion efforts with other agencies. Table 1-1 summarizes the coordination with other agencies. 1.1 Purpose The purpose of this U~r/MP is to ensure efficient use and promote conservation of urban water supplies within the City of Ukiah (City), California. The U\X/MP describes the availability of wa[ec and discusses water use, reclamation, and water conservation activities. 1.2 Urban Water Management Planning Act Brown and Caldwell prepared this plan Eox submission to the California Department of Water Resources (DWR) on behalf of the Ciry as required by the Urban Water Management Planning Act (Act) (California \x'aier Code Division 6, Part 2.6, Sections 10610 through 10657). Water Code Section 70620 requires any water supplies that provides water to 3,000 ox more customers, or that provides over 3,000 acre-feet of water annually, to prepare an Urban Water Management Plan that complies with lX~atex Code Sections 10630 and following. Urban water suppliers axe required to develop water management plans to activel}' pursue the efficient use of available water supplies to meet the needs of its various categories of customers during normal, dry, and multiple dry years-. The dct describes- the contents- of the U~~~IvIP as well as how urban water suppliers should adopt and implement the UWMP. It is the intention oEthe Legislature, in enacting this pan, to peanut levels of water management planning commensurate with the numbers of customers- served and the volume of water supplied. T'or ease of review, the DWR Review Sheets axe located in Appendix ;1. 1.3 Previous Reports Two reports and the Ci4~ and Mendocino County (County) general plans were used in preparing this UWMP. Also, Bartle ~X/ells and Wagner and Bosignore were contacted. Bartle Wells is a consulting firm that specializes in fmancing and Wagner and Bosignore specialize in water right issues. Included in this U\rMIP is a pxeliminarv analysis completed by Wagner and Bosignore on the reduction of flow in the Eel Kiver. This analysis is located at the end of Chapter 3. The reports and information obtained from the consulting firms address the water supply and demand Eor the City. An understanding of the results of these previous documents provides a broader contest Eox preparing an updated water management plan. The following paragraphs provide a summary of the documents. Water Rate Study and Preliminary Financing Plan, 2005. "Phis financing plan reviews the existing rate structure and evaluates fmancing alternatives available to the City for water system capital improvements. This financing plan recommends updates to the water utility rate structure and connection fee. Urban Water Management Plan 2002. "I'hc 2002 UWMP was prepared by Kenned}' Jenks, an engineering consulting firm hired by the Ciry to fulfill 2000 UWMP requirements. The main purpose of this plan is to analyze the CiR°'s water supply and demand Eox the following 25 years during normal and drought years.

DESCRIPTION OF EXISTING WATER SYSTEM This chapter describes the City's water system. It contains a description of the service area, its climate, and the water suppl}' Eacilidcs including surface water supply system, groundwater wells, res-ervoixs, and piping system. 2.1 Description of Service Area The City is a general law city incorporated in 187C,. The City has- been providing reliable, safe drinking water to Ukiah residents since 1880. "Phe City was- granted a water supply permit ~ the Division of y~'ater Resources (a division of the Department of Public Woxksl in 1939 to supply domestic water to the City and vicinity. The permit was revised and xeissucd in 1953, and again in ,april 1962. In 1987, a tcmpoxaxy permit was issued to the City that cxpixcd on December 1, 7982 A requirement of the temporary permit was to submit a report demonstrating that the Citv's Ranney collector provided effective and reliable treatment for the removal and inactivation of enteric viruses and Giardia Lanrblia organisms. The City decided not to complete the report, and instead, decided to construct a water treatment plant for use with the Ranney collector. Construction of the water treatment plant was completed in Apri] 1992. The Citv currently opexatcs the wafer treatment plant under DI-IS Water supply Permit No. 09-93-007. The service area fox the water system is not conterminous with the City's boundaries. "l'he Ciro serves a small number of customers outside its limits and its dace of use (The City latest petition includes tins are located outside its place of use). d location map of the City is shown in Figure 2-1. "l'hree other water systems bound the Citv. Millvicw County Watcx District (CWD) is located to the north, Willow CWD is located to the south, and Rogina Water Company is located to the east. Of these four water systems, the City serves the lazgest population, with a population over 15,600. The total number of connections is approximately 5,700. As nr_wiously discussed. Eox ~urooses of water planning, the City assumes that wk~itlnn the nest 20 years, the Cip- ims-p}arr.+-tHV<_ill annex and provide water scroiccs to land within its sphere of influence.

The area is centrally located between San hxancisco, Eureka, and Sacramento. The Cit}' is surrounded by coastal ranges in southern Mendocino County and situated in the fertile Yokayo Valley with rich vineyards and pear orchards- The valley is bordered on the west by the Mendocino Range and on the east by the Mayacamas Mountains. Elevations in the mountains axe over 1,800 feet mean sea level (MSL), while elevations in [he valley range from about 670 feet MSI, in the north near Calpclla to about 560 2.1 DRAFT for review purposes only.

Annual rainfall in the Ciry is about 35 inches. Most of the precipitation falls from December through April, and only at ldghex elevation is there substantial snowfall. Rainfall is often from intense rains caused by large storms that move in Exom the northwest. Virtually no rainfall occurs during the summer months The average growing season is about 260 days on the coast, 210 days in the interior valleys including the Ukiah area, and 180 da}'s in Round Valle}' (Mendocino County General Plan). Table 2-la and 2-7b summarizes montlily averages taken from 1989 to 2005. Da[a were obtained Erom the California Trrigation Management Information Svs[em (CIMIS) website for the I Iopland Station in Mendocino County (Station Numbers 85 and 106).

The table provides information on evapotxanspication (F."To), rainfall, and average tcmperamcc. ETo is the Toss of water to the atmosphere by the combined processes of evaporation (from soil and plant surfaces) and transpiration (Erom plant tissues).

Stream flow responds duecdy to the rainfall pattern; high flows will drop quickly without sustaining rainfall. During the dry summer months, stream Elow consists of groundwater seepage, channel storage, ox reseroov storage. In the Russian River Basin, 93 percent of the average seasonal runoff occurs in a five-month period beginning in December and ending in April (Mendocino County GGeneral Plan). 2-5 DRAF? for review purposes only- P'.\12 0 ,128619 kiah UWMP1Drafl Re o A 2 71Draf UWMP 10122007 do '. 2: Description of Existing Water System 2005 Urban Water Management Plan 2.3 Water Supply Facilities and Sources Water supply is defined as the amount of water available from a source ox combination of sources (e.g., streams, rivers, ponds, lakes, groundwater, ete.) for use by a water purveyor. '1 he Ciry currently obtains all of its water supply from the underflow of the Russian River and one percolating Qroundwater well. The City is not a wholesaler. Pursuant to a Water Supply Contract, the City can purchase up to 800 acre Eeet annually of project water from the Mendocino County Russian River flood Control and Water Conservation District. Additional details regarding sources of water axe included in Chaptcx 3. 2.3.1 Surface Water (Ranney collector and Wells 3 and 5) The City's surface water supply is obtained from a Ranney collector and Wells 3 and 5, which draw water from an alluvial zone (underflow from the Russian River) along the Russian River. Even though the Cih' is not taking water directly from the Russian River, these water supplies arc considered undexflow of the Russian River, and therefore, arc considered surface water sources. The following paragraphs describe each of the surface water sources. Ranney eollettor. The City collects undexflow from the Russian River through its Ranney collector located along the river's banks. The Ranney collector was constructed in 1966 with a design capacity of 13 million gallons per da}' (mgd), which is equal to the City's water right. The maximum capacity obtained Erom the Ranney collector was 9 mgd, well below its design capacity. 1'he Ranney collector has steadily declined from 9 mgd to its current capacity of 4.8 mgd. The significant loss in capacity of the Ranney collector may be a result of changes in the Russian River channel moving away from Ranney collector and the compaction of clays and silts in the riverbed over the Ranney collector. ,Another concern is the Ranney can only be used approxima[dv six months a year during the drier weather months. During the rainy months, the turbidity in the Russian River increases, which increases the htrbidity of the water in the Ranney collector. "l'he Microtloc contact clarification-filtration units located at the W'IT' cannot be operated efficiently under high turbidity conditions. It is not possible to rely on the Ranney collector as a water supply source during the winter when the turbidity of the Russian River is high. Well 3: 'I'lris well has an estimated pumping capacity of 650 gym. It is used throughout the year. Well 5: The capacity of Wcll 5 is 300 gym. "['his well can only be used when the Ranney collector is not in service. 'T'his Wcll is equipped with a standby engine-driven pump. Well 1, 2 and 6: Wells 1, 2, and C axe no longer used by the City. Well 1 has been out of service since the 1970'x. Wells 2 and 6 (~Y/atex Erom ~X7e11 6 i~was pumped into Well 2) were removed from the City's latest domestic water supply permit and may no longer be used as a source of supply. Wells 2 and 6 had to be taken out of service during construction of the new t.5 million gallon dearwell Eor the Water Treatment Plant IE a water supply well is removed Ecom service for more than a year, it must comply with current DHS standards. The cost to rehabilitate the wells to meet llI IS standards, which would require installation of an annular seal and electrical upgrades, make it economically infeasible to return these wells to sercrice. The pumping capacirv of Wells 2/6 is only 50 gallons pee minute (gym). Even though it is not cost effective to rehabilitate Wells 2/G Eox the Cirv's water supply, Wcll 6 could be used as-trin its present condition to irrigate the adjacent sofrball complex fields, which would reduce the potable water used for irrigation. Since 2003, the City has undertaken an aggressive rehabilitation program of the existing surface water wells-. The capauty of the wells has increased as a result of the work but increased demands arc pushing the water pxoducdon capabilities beyond their pumping capacity. 2-B DRAPT for review purposes only.

Well 4 is a drilled well and has an estimated capacity 800 gpm (City of Ukiah Summary of Water Rights, Wagner and Bonsignore). The facility is equipped with a standby engine-driven pump. There is no maximum amount or limitation on the season of diversion associated with this- source. 2.3.3 Water Rights Prior to 7914, a right to use surface water could be established without filing Eor a permit from the State Water Board under the Water Commission Act After 1914, a right to divert water Erom a surface water source or undexgcound water flowing in a definite channel, requires a permit from the State Water Board. Water can be pumped Erom percolating groundwater without a state issued permit A water right is the legal entitlement that authorizes water to be diverted by a user from a specified source (water supply) Eox a beneficial, non-wasteful, use. "Lhe water right under a state issued permit spells- out the point of diversion, amount or rare of water that can be divested, place of use and the purpose of use. Wagner and Bonsignore, an engineering firm specializing in water rights, was consulted to determine the details of the Cin~'s water rights.

'1'hc City has Pre-1949 Appropriative Right for 2.8 cubic Eeet per second (cfs) Eor diversion from the Russian River for a maximum of 2,027 acre-feet (AF) annually. This water right is recognized in State Water Rights Board (predecessor to State ~Vatex Resources Control Board) Decision 1030. Water Right Permit 72952 -Post-1949 Appropriative Right. Watcx Right Permit 12952 (Application 15704) provides for the diversion of Russian River underfloor fox municipal purposes. Under this Permit, water can be diverted at a rate not to exceed 20.0 cfs (9,000 gpm) from Januarn 1 through llecembex 37 (with no annual limit). The face value of the City's Pre-1949 and Post-1949 appropriadve rights is approximate]}' 14,480 AF annually(but s'ee discussion in Section 3 10 which assumes that the City will use approximately 8400 acre-feet annually when it firs- pumps 20 cfs at its peak usage time) - 'phe Permit is considered aPost- 194') water right, which is a right that was initiated subsequent to the authorization to construct Coyote Valley Dam in 1949.

WATER SUPPLY QUANTITY AND QUALITY ~s noted in Chapter 2, the City uses both surface water and percolated groundwater as its supply sources. This chapter describes the surface water and percolated groundwater souxees, quantities, supply constraints, and the water quality of the water supply souxees. In addition, this chapter describes current and projected water supplies, water supply reliability and vulnerability, water shortage expectations, and water shortage revenue and expenditure impacts. 3.1 Surface Water Section 3.1 provides- a description of the City's surface water supply as well as tine physical and legal constraints of this supply. Curcendv, the City uses surface water sources diverted from the underfow of the Russian River. The surface water sources consist of the Ranney collector and Wells 3 and 5. These surface water sources are located along [he Russian ffivex on the east side of the service area. 3.1.1 Description Water Right Permit 12952 (dpplication 15704) provides Eor the diversion of Russian River undexflow Eor munidpal purposes. Undcx this Permit, water can be diverted at a rate not to exceed 20.0 cfs- from)anuary 1 through December 31. The City collects undexflow from the Russian River through its Ranney collector and Wells 3 and 5, which aze located along the river's banks, pursuant to its Permit 12952. The Ranney collector has an esisdng capacity of 3,400 gallons per minute (gpm) or approximately 4.8 million gallons per day (mgd). The available capacity of the Ranney collector is significantly less than the designed capacity- of 13 mgd, which is equal to the City's water right The maximum capacity obtained Exom the Rannev collector was 9 mgd, well below its design capacity,. "1'he Rannc}' collector has stcadIly declined Erom 9 mgd to its current capacity of 4.8 mgd. The significant loss in capaciq of the Ranney collector may be a result of changes in the Russian River channel movuig away from Ranney collector and the compaction of clays and silts in the riverbed over the Rannev collector. Another concern is the Ranney can only be used appcoxunately six months a year during the drier weather months. During the rainy months, the turbidity- in the Russian River increases, which increases the hirbidiry of die water in the Ranney collector. The Microfloc contact dariflcation- filtration units located at the ~X/'IP cannot be operated efficienfl}' under high turbidity conditions. It is not poss-ibie to rely on the Ranney collector as a water supply source during the winter when the mrbiditc of the Russian River is- high. The water treatment plant (WTP) was placed into service in April 1992. The source of water for the ~C-'TP is the Rannev collector. Water is pumped from the Ranney collector to the AGTP. 1'he WTP has a name plate capacih- of G.0 mgd and was designed to be expanded to 9 mgd. In 2006, a third fdtcation unit was added to provide reliability' and redundancy as required by llI IS. The third unit does not increase treatment capacity. 3.1.2 Physical Constraints The Ranney collector was constmaed in ]966 with nine laterals that extended beneath and along side the Russian River. One of the laterals, believed to be htcxeasing water tuxbidirv, was plugged and abandoned in April 1981. The Ranney collector cuxxendy produces about 4.8 mgd (appxosimately 3,400 gpm).

The Permit is still valid while the Petition Eor Extension of Time is processed. The City has begun the process of preparing an environmental impact report (EFR) in support of its application fox an extension of time and tES-the City's pending Petitions- to change its points of diversion and place of use It has completed an initial study, conducted a scoping session and is cuxrentle evaluating its response to comments on the proposed scope of the EIR. The City has steadily increased its use and has been diligent about maintaining its water right. The State Water Board is empowered to grant an extension of time to put water to beneficial use upon a showing to the Board's sadsfacdon that due diligence has been exercised, that failure to comply with previous time requirements has been occasioned by obstacles which could not reasonably be avoided, and that satisfactory progress- will be made if an extension of time is granted. (See 23 CCR §841.) According to City's Water Right Engineer, Robert C. Wagner, the Ciro should be able to make the required showing of due ddigencc, since through no fault of the City, the demand fox water has not developed as quickly as was anticipated when the City's permit was issued. The State Water Board wrote in WRO 2000-13, 1n [he Matter of the Petition for Extension of Time of the City of San Luis Obispo, Permit 5882 (d1021G)... "a municipahR such as San Luis Obispo is to be afforded some latitude in putfing water to beneficial use, because the municipality must be able to plan for, and meet, the needs of its existing and Eumre citizens (lY7arer Code section 106.5, 1203.)" In Mx. Wagncr's opinion, it is- reasonable to expect that similar latitude would be granted to the Ciq~ of likiah to develop full beneficial use of its water rights. Water Board approvals- of successive extensions' of time for murvcipalities to allow fox~radu~tl development has been the norm js a mltter of ctatutor}_polic~'yX'ater Code. sec 106 5~, municipal water rights are to be "protected to the fullest extent necessary fox existing and furore uses "The greater deference shown a municipality is counter balanced b}' the allowance of tempoxazv permits fox the use of excess municipal water by other parties pending the expansion of the municipality's use (\~'ater Code_ sec. 1203E There does not appear to be any obstacles to approval of the changes in points of diversion and place of use, subject to California Environmental Quality tier review. The City's request fox an extension of time to make full beneficial use of water under its permit does not require a showing of water availability since such a finding was made by dre predecessor to the State Water Board in llecision 1030. However, the City conducted and has- included herein an analysis showing there is water available to meet its projected ultimate demands. The \ti'ater Board's declaration that tins segment of the Russian River is fully a~orooriated takes account of the Ctty's 20 cfs ~xxnit amount as well as other pre-existing rights (~~'atcc Right Order 98-081. In order to grant the City's Petition to change points of diversion and place of use the ~C'atec Boazd will need to make a finding that "the change yvill not operate m the injux~of any legal user of water involved" (l~'ater Code. sec 1702) In relation to junior appropriators. the City has a priority right to the beneficial use of water uP to the Hill volume or rate authorized in its ap~pr~nriadve permit Beneficial use within that volume and sate does no[ in itself equate to injury to jtmiocs under the "non-inju~r -" rule.

The City's pexcoladnggxoundwatex supply consists of Well 4 with a capacity of 1,290 dbY. 3.2.1 Description The Ukiah Valley groundwater basin (Number 1-52 as described in California Department of Water Resources Bulletin 118) is located in southeastern Mendocino County and is the largest basin along the Russian River. It is approximately 22 miles long and 5 miles wide. The basin is part of the Ukiah and Redwood Valleys to the north and their tributary valleys. 'T'his basin is not adjudicated. A groundwater management plan has not been prepared fox the Ukiah Valley ox Mendocino County. Based on information currently available to the City, the groundwater supplies are adequate to meet e_cisting and future demands. There is published data available providing information on the storage capacity and groundwater levels within the Ukiah Valley Gxoundwatex Basins. United States Geological Survey (IISGS) published Water Resources Investigation Report 85-4258, "Groundwater Resources in Mendocino Counro, California" concludes the following: • Gxoundwatex wells in the Ckiah Valley Gxoundwatex Basin moniroxed over a 30 veax period show no pxominentlong-term declines. • Hvdrograph analysis indicates the Basin is recharged fully each year except when precipitation falls below GO percent of normal. • During the drought of 1976/77 when rainfall was less than 60 percent of normal, the groundwater wells recovered to normal levels by the end of the 1978 rainfall season. 1'uxthex, California Department of Wa[ex Resources Bulletin 118 °Califomia's Gxoundwatex" concludes the following: • Groundwater in storage in the upper 100 Eeet of the most productive area of the Ukiah Valley is estimated at 90,000 acre-feet. • i1n additional 45,000 acre-feet of groundwater storage is located within the margins of the Ukiah Vallee. • Groundwater levels in the Ukiah Valley Groundwater Basin for the past 30 years have remained relatively stable. • During drought conditions there is increased drawdown of groundwater levels, but the levels recover in post-drought conditions. In general, [he Ukiah Valley groundwater basin will experience seasonal and yeaz to veax variation in water levels due to chmate and pumping stresses. However, these variations tend to be small. Water levels decline in the dry months and some wells may experience declines during successive dry years. But water levels in general have always recovered. There does not appear to be a long term decline [hat would suggest shortage ox overdraft in dte Ukiah Valley. The basin is not considered overdrafted and is not currently projected to be ovexdxafted. The preparation of a groundwater management plan is not merited at this time because of the modest increases in demand. Table 3-1 lists pexcolatinggxoundwatex pumping Eor the City.

According to the Garrapala decision, fox groundwater to be classified as surface water subject to appropriation, the following conditions must exist 1. A subsurface channel must be present; 2. 'fhe channel must have relatively impermeable bed and banks; 3. The course of the channel must be known or capable of being determined by seasonable inference; and 4. Groundwater must be flowing in the channel. The Gaaapa[a derision, interpreting section 1200 of the Water Code, was followed and applied in the 2006 opinion of the Firs[ District Court of r\ppeals in the case, North Gualala II'ater Company v. State Water Ree~ourre,r Board (]39 Cal. ~lpp. 4v6 li77). That decision was left standing by the California Supreme Court. In the Ukiah Valle}', increased interest in the issue of legal classification has- arisen since the Division of Water Rights took the position that the groundwater pumped at the wells of the I Iopland Public Utilities Dis-ttict (PUD~ and the Willow Count}- Water District is subject to SWRCB permitting authority. However, no formal decision has been rendered by the Board itself. r~s to the City of Cl-.iah, there has been no legal classification by the ytnc~State of California on e€the ground water that might be pumped by the Ciry in the fumxe. The burden is on the party asserting that groundwater is flowing in a defini[e channel. The Legal presumption is that well water is pexcolanng groundwater. Using the applicable legal standards and the available data, [he Ciry will make a determination regarding whether future wells requite an appropciative sights- permits from [he SWRCB. 'phcie has been general acceptance by the Division of Water Rights- staff that existing Well 4 pumps percolating groundwater. 3.3 Desalination There ate no reasonable opportunities for the development of desalinated water within the City's service area as a future water supply source because of the City's location relative to a source for desalination.

The CiTy-has completed or will complete in the near future several projects to help offset the lack of pumping capauty. The Ciry began a well siring study in Mav 2006 to add two groundwater wells with a total capacin~ of 1,500 gpm. "Those new groundwater wells will increase pumping capacity to reliably meet present peak demands and water demands during drought conditions. I [owever, additional water supply will be needed to meet water demands within the Cifi's sphere of influence The Cifi recently constructed three new storage tanks to meet DI IS regulations. Improvements to the City's WTP were completed in September 2006. The WTP improvements comply with new California DHS regulations to ensure adequate rehabilih~ and redundancy.

The City continues to explore various altemadves [o improve xeliabilin and reduce vulnerability. "phe City is cuxrentiy investigating additional groundwater well sites. 'T'hat investigation will include a determination as to whether the groundwater is percolating groundwater ox gxoundwatex flowing in a definite undecgxound channel. 'I'o the extent the Citv is able to develop additional percolating groundwater wells, this would enable the City to rely more on percolated gxoundwatex than i[ does at pres-enr. 3.7.1 Reliability Comparison California has experienced two droughts over the past 30 years, one severe drought in 1976/19?7 and a prolonged drought from ] 987 to 1993. During bode drought periods, the City did not ex-pevencc any shortages in its water supply. Customers volumarily cut back their water usage during this time to help the City meet demands and demonstrate their concern fox the statewide drought conditions.

The ordinance is intended to prohibit all nonessential water uses, and to allocate the available water supply during amt water shortage emergency. The City has not needed to declare any water shortage emergencies due to lack of water supply. Emergency simanons that have been declared have been the result of problems with water treatment ox distribution facilities. The Ciro has been able to manage these emergency situations by restricting the watering of Ciry parks and landscaped areas. Notification of any water shortage emergency condition in the City will follow the guidelines set forth in [he City's Water Quality Emergency Plan. The City will first notify local an[horides, cadio, newspaper, and television media to inform them of the current status of the emergency. If needed, the Ciry will contact neighboring water districts for mutual aid. IE no other means is available, the Ciry will notify customers on a house-to-house basis of the emergency and what voluntary ox mandatory measures need to be implemented. 3.9.1 Estimate of Minimum Water Supply for Next Three Years This section outlines the estimated three-year minimum water supply, the actions and stages described in the Ordinance that will be implemented in the even of a water supply shortage, and the emergency preparedness and plans fox catastrophic events. ~1s was demonstrated by the hypothetical four-year rrrinunum water supply scenario in Section 3.7.7, a ~9 'iPreducdon in the City's overall water supply does not require the City to declare voluntary- or mandatory rationing of water because of a shortage of water supply.

The City holds, among other water rights, a 1954 appropriative water right permit for 20 cfs from Russian River Underflow. This amount corresponds to approximately double the current water use. Physical water availability is expected to be affected by significant reductions in Eel River imports to the Russian River basin. Analyses were conducted to assess impacts to Lake Mendocino operations in response to reduced Eel River imports and to determine the effect on future water supply downstream of Lake Mendocino. The results show sufficient water supply available for the City and that increased diversions by the City will have only minor effects on Lake Mendocino operations. The City does not control Lake Mendocino and can not cause changes to the release requirements or the amount of Eel River imports. Those decisions are controlled by other agencies. The following analysis shows that under a given set of assumptions there is sufficient water to mimic past releases during the summer months with the result that the reduced imports from the Eel River that are expected will not substantially affect the flow in the River. Lake Mendocino may experience significant changes in seasonal water surface due to reductions in imports, but since the City does not take water out of the lake directly it does not directly affect water levels or storage. It is important to note that the source of the City's water right is Russian River Underflow which has several components including, Russian River (West Fork), ungaged tributary inflow, groundwater accretion, return flow, percolation of direct precipitation and natural flow from the East Fork Russian River and Eel River imports. to addition the City pumps percolating groundwater from at least one of its wells. The following analyses treats all water supplies and all water diversions as having an equal effect on the system. This particular assumption as explained in more detail below is a simplifying and conservative assumption; the actual impacts are very likely to be less than the modeled impacts attributable to the City. Prepared by Waener and Bonsienore 3.1 g The first part of the analysis estimates the rate and timing of increased depletions to the Russian River attributable to future City of Ukiah diversions. This is described in Section 1. The second part of the analysis establishes a future baseline condition for Lake Mendocino and the Russian River. This was necessary because hydrological conditions in the Russian River basin have changed over time; future water supply and management will not be the same as historical. Two future baseline scenarios were developed because of uncertainty regarding future water resource management. Because the City has no control over the water supply to Lake Mendocino or bake operations, the City cannot predict how the system will be operated. Section 2 describes the future baseline scenarios. The third part of the analysis applied the estimated increased City of Ukiah river depletions onto the baseline scenarios to see how streamflows and/or reservoir operations may be affected. This is presented in Section 3. SECTION 1 - Proiected Increased Diversions by City of Ukiah City of Ukiah annual treated water production has increased from about 2,200 acre-feet in 1960 to about 4,000 acre-feet in recent years, as shown in Figure 1. Peak water use in the City typically occurs in July. The recent monthly water use pattern by the City was used to project annual water use corresponding to 20 cfs in July. State Water Rights Board (predecessor to the State Water Board) issued a permit pursuant to Application 15704 to the Citys to divert up to 20 cfs. Based on 20 cfs use in July and the average monthly water use pattern, the annual use would be 8,394 acre-feet. Though the City has apre-1949 water right for 2.8 cfs and also pumps percolating groundwater, the analysis conducted assumed an ultimate demand of 20 cfs. Historical water use by the City of Ukiah is already reflected in historical Russian River flows. To evaluate future conditions with the City of Ukiah diverting 8,394 acre-feet per year, it was necessary to model an increase in water use corresponding to the difference between the historical use and the projected level of 8,394 acre-feet. A portion of the water diverted by the City for municipal use returns to the groundwater system directly via percolation ponds at the wastewater treatment plant. Essentially all of the Prepared by Waener and Bonsignore 3-19 water used indoors returns to the groundwater system within the same month as diverted. It was estimated that 15 percent of the outdoor water use returns to the river system (also assumed to be within the same month as diverted). Water use during the winter months was taken to be a good estimate of indoor water use during the rest of the year. For each month, an estimate was made of the fraction of diversion that resulted in depletion to the River system. Figure 2 shows the average monthly water diversion and depletion corresponding to a 20 cfs peak diversion. The annual increase in water use from historical levels up to 8,394 acre-feet per year (corresponding to 20 cfs in the peak month) was distributed by the average monthly pattern of water use and then multiplied by the depletion fraction of diversion for that respective month to estimate the increased draft on the river system corresponding to full use of the City's appropriative right. This increased draft (depletion) was then imposed on the model of Lake Mendocino and the Russian River to evaluate releases or streamflow. SECTION 2 -Future Baseline Scenarios for Russian River In this part of the analysis, models of Potter Valley imports, Lake Mendocino operations and Russian River flows were developed and used to establish a future baseline condition upon which the City's diversions were evaluated. The historical hydrology was used to establish a baseline condition. However, historical events will not be repeated because of two significant resource management changes. In 1986, State Water Resources Control Board Decision 1610 (D-1610) was issued setting forth minimum required streamflows on the Russian River below Lake Mendocino. Operations prior to that time did not need to meet D-1610 requirements. Then in 2004, the Federal Energy Regulatory Commission (FERC) amended the hydroelectric license for the Potter Valley Project. The amended license is expected to significantly reduce imports from the Eel River. In the analysis of future baseline conditions, future Eel River imports were projected by applying the amended FERC license to the hydrology of 1961 through 2006. This resulted in less imports than occurred historically. Lake Mendocino operations were modeled to reflect Flood control operations and release of water to meet downstream demands. Downstream demands Prepared by Wanner and Bonsienore 3-20 were projected in two different fashions, creating a Scenario A and Scenario B. In both scenarios, the downstream demand was based on historical irrigation and municipal use and included a projection of the D-1610 requirements to the full 1961 through 2006 study period. Eel River Imports The East Fork of the Russian River receives significant imports from the Eel River via the Potter Valley Project operated by PG&E. The historical imports, excluding the portion delivered to the East and West canals of the Potter Valley [rrigation District, averaged about 141,500 acre- feet per year, as shown in Table 1. This represented about 57 percent of the inflow to Lake Mendocino. Table 2 summarizes the monthly inflow to Lake Mendocino as reported by the US Army Corps of Engineers (USAGE) and shows that it averaged about 250,100 acre-feet per year. On January 28, 2004, FERC amended the license for the Potter Valley Project (Prof. 77- 110). This license specifies minimum flows for both the Eel River and diversions to the East Fork of the Russian River. The minimum diversion to the East Fork of the Russian River is conditioned on time of year and hydrological classification, as follows. Minimum Diversion to the East Fork Russian River Period Classification From Through Normal Dry Critical Sep 16 Apr 14 35 cfs 35 cfs 5 cfs Apr l5 May 14 35 cfs 25 cfs 5 cfs May 15 Sep I S 75 cfs 25 cfs 5 cfs 'i'he hydrological classification is determined from unimpaired inflow to Lake Pillsbury (located in the Eel River basin). Table 3 summarizes the classification determined in this analysis. The FERC license also includes a condition (paragraph E5 on page 63) that disallows diversions to the East Fork Russian River in excess of the specified minimum flows, whenever Prenared by Wanner and Bonsi€;nore 3-21 the storage in Lake Pillsbury is less than Target Storage Curves included in the license. Figure 3 shows the Target Storage Curves. Figure 3 also shows the maximum storage in Lake Pillsbury corresponding to the Certificate of Approval (attached) issued by Division of Safety of Dams on December 4, 1978. The Certificate states that water may be impounded to elevation 1910.0 but the spillway gates must be open from November I to April I. The capacity table for Lake Pillsbury (attached), made by PG&E and dated October 2006, shows the top of spillway gates at 1910.0 feet, which corresponds to 74,993 acre-feet of storage. The spill gates are 10 feet tall. The 2006 capacity table shows the spill crest at 1900.0 feet which corresponds to 54,338 acre- feet of storage. These capacities, 54,338 acre-feet from November through March, and 74,993 acre-feet from April through October, are shown as Maximum Storage in Figure 3. Because the Target Storage Curves are above the Maximum Storage levels, Condition ES results in a severe restriction on imports of water through the Potter Valley Project from March 5 to July 17. [n an October 16, 2006, letter (attached) from John Keenan, Sr. Vice President, PG&E to Magalie Salas, Secretary, FERC, Mr. Keenan explained that computer modeling conducted in development of the flow proposal incorporated in the FERC license allowed maximum diversions through the Potter Valley Project tunnel during times of spill at Cape Horn Dam (located on the Eel River immediately downstream of the tunnel diversion). Mr. Keenan further explains that the final language of the license did not incorporate that allowance. We do not know why that allowance was not included in the final language. The diversions to the Russian River through the Potter Valley Project during the spring months will be severely restricted by the existing language unless the condition is modified. An estimate was made of future inflows to Lake Mendocino based on Eel River imports being restricted to the specified minimum diversion from March 5 to July 17. While the ES condition would not affect the balance of the year, other requirements of the amended FERC license could affect Potter Valley Project diversions during the balance of the water year. Considerable additional computer modeling would be required to simulate operations in the Eel Prepared by Wainer and Bonsi€tnore 3-22 River basin and even with such a tool, considerable discretion for diversions remains to PG&E.~ Based on the assumption that PG&E would be able and willing to maximize flow through the Potter Valley Project tunnel for power generation, it was decided that using historical imports for the July 18 through March 4 period would be a reasonable assumption in this analysis. Table 4 summarizes the Potter Valley Project import to East Fork Russian River as affected by the ES license condition. Note that (between Table 1 and Table 4) average annual imports drop 37,300 acre-feet or 26 percent. It was assumed for this analysis that an acre-foot less import translated into an acre-foot less inflow to Lake Mendocino on the same day. Downstream Demands on Russian River The historical record of outflow from Lake Mendocino provides an indication of water demand from Lake Mendocino downstream on the Russian River from the East Fork Russian River to Dry Creek. A USACE database provided a daily record of outflow from the lake for water years 1961 through 2006. A monthly summary of Lake Mendocino historical outflow is provided in Table 5. Note that releases from the lake were much higher in the wet season of December through April. These high flows were not intended to meet downstream demand but rather resulted from flood control operations in Lake Mendocino. Downstream demands on the Russian River to Dry Creek during the wet season of December through April were estimated based on application of the D-1610 minimum streamflow requirements to the period of record, 1961 through 2006. Downstream demands on the Russian River to Dry Creek for instream flow, recreation, agricultural use and municipal use during the dry season of May through November were estimated in two different ways, leading to two Scenarios. In both scenarios, historical Lake In a June 8, 2009, letter (attached) from Randy Poole (General Manager, SCWA) to David Moller (Manager of Relicensing, PG&E), Mr. Poole states, "The Agency and the County still do no[ know how PG&E is operating the Project, or whether operating the project using other criterion that is also consistent with the existing Federal Energy Regulatory Commission (FERC) license could have resulted in higher Lake Mendocino storage." Mc Moller responded to Mr. Poole in a June 22, 2007 letter (attached) and acknowledged that "the reduction in diversions from the Eel River into the EBRR [East Branch Russian River] required by [he license amendment was considerably greater than what had been anticipated during the amendment proceeding" but did not provide an explanation of how PG&E is operating the Potter Valley Project. Prepared by Wagner and Bonsignore 3-23 releases during the dry season were used as a guide. Table 5 shows historical lake releases in the period May through November were typically in the range of 12,000 to 18,000 acre-feet per month. That corresponds to a rate of 200 to 250 cfs. Figure 4 shows the distribution of historical daily releases from Lake Mendocino during the months of May through November. This figure shows the percent of days during May through November that the Lake release exceeded the given value. "fhe median flow was 230 cfs. Only 27 percent of the daily releases were greater than 275 cfs. The higher release rates suggest that there were surplus releases and thus were not considered to represent demands on the Russian River. Scenario A estimated downstream demands on the Russian River for release from Lake Mendocino as the historical daily release capped at 275 cfs. In other words, historical daily releases less than 275 cfs during the dry season of May through November were assumed to be the measure of downstream demand for fisheries, recreation, agricultural and municipal uses. On days when the May though November release exceeded 275 cfs, the downstream demand was assumed to be 275 cfs. D-1610 specifies a minimum instream flow from the East Fork Russian River to Dry Creek for all months of the year. If any of the historical Lake releases during May through November were insufficient to meet the D-1610 minimum requirement, the downstream demand in Scenario A was adjusted to satisfy the D-1610 requirement. The D-1610 minimum streamflow requirement was instrumental in estimating downstream demands in Scenario B. Review of historical gage records on the Russian River between Lake Mendocino and Dry Creek show river flow in excess of the D-1610 requirement. Scenario B downstream demand for release from Lake Mendocino was estimated as the historical Lake release minus the amount that the minimum gaged flow in the river exceeded the D-1610 requirement. Both estimates (Scenarios) of downstream demand on the Russian River were based on historical Lake releases rather than a cataloguing of water rights or water diversions on the Russian River. In Scenario A, the assumption was that historical Lake releases (up to 275 cfs) Prepared by Waenerand Bonsignore 3-24 were necessary to meet demands. [n Scenario B, the assumption was that if the historical Lake release, after providing for all diversions and river channel losses, resulted in river flow in excess of the D-1610 requirement, then the Lake release could be scaled back. Scenario B is an inquiry into whether or not there had been historical releases greater than needed. A further inquiry into the actual historical demand would be necessary to confirm this assumption. Lake Mendocino Operational Anal A spreadsheet model was constructed to simulate Lake Mendocino operations. A daily time step over the 46-year period of record (water years 1961 through 2006) was modeled. A daily record of historical storage content in Lake Mendocino was provided from a US Army Corps of Engineers database. In the operational analysis during the wet season of December through April, releases were made for flood control and to maintain the D-1610 minimum streamflow. Rather than trying to incorporate in the model all the factors involved in flood routing, including discretionary encroachments into the flood reservation, the modeled reservoir content was required to be no greater than the historical content during the months of December through April. During the May through November dry season, the downstream demand corresponding to the respective Scenario (A or B) was released from the reservoir. Also, to reflect the flood rule curve, releases were made during the dry season as necessary to keep the Lake below 91,000 acre-feet of storage. Future Baseline Operations Figure 5 shows the average monthly outflow from Lake Mendocino under historical and projected future conditions. Outflows during the dry season are greater in Scenario A than in Scenario B. In Scenario A, outflows replicated historical releases up to 275 cfs. [n Scenario B, outflows were reduced to the minimum rate needed to satisfy the D-1610 required flow down to Prepared by Wagner and Bonsi¢nore 3-25 Dry Creek. The lesser Lake release during the dry season in Scenario B supports higher Lake levels, shown in Figure 6. Compared to average historical Lake levels, Scenario A Lake levels in July and August are approximately I I feet lower and Scenario B Lake levels are approximately 6 feet lower. SECTION 3 -Modeling of Increased City of Ukiah Diversions in Russian River Future Baseline The effect of the City of Ukiah's increased diversions was then modeled as a change to Future Baseline Scenarios A and B. In Scenario A, it was assumed that the increased depletion to the river system attributable to Ukiah's diversion would necessitate an increased release from Lake Mendocino. In Scenario B, it was assumed that Ukiah's increased depletion to the river would necessitate an increased release from Lake Mendocino whenever that depletion would cause the river flow to drop below the D-1610 minimum flow requirement. Because the City's depletion would affect the river below the confluence of the West and East Forks, there would be times when the increased depletion would not necessitate increased Lake release. If the minimum historical gage flow was at Hopland, Cloverdale or Healdsburg, the increased depletion by Ukiah would necessitate additional release from Lake Mendocino. If the minimum gauged flow occurred at the confluence of the Forks, no additional release would be required. Note that the minimum flow requirement in D-1610 affects the river from the Forks to Dry Creek and is assumed to apply along this entire reach. It would be possible that the flow could be below the minimum at the Forks, and higher than the minimum at Hopland, Cloverdale and Healdsburg, in which case a release of stored water to maintain the minimum flow would not be required. Figure 7 shows the average outflows modeled for Scenario A, with and without the increased diversion by City of Ukiah. Figure 8 shows the effect on Lake levels due to Ukiah's increased diversion under Scenario A. Slightly greater outflows are required in the dry season, resulting in slightly lower Lake levels. During the wet season, outflows for flood control are reduced, allowing the Lake levels to rebound to baseline conditions. Figure 9 shows the modeled Lake outflows for Scenario B, with and without Ukiah's increased diversion. Figure 10 shows the effect on Lake levels due to Ukiah's increased Prepared by Waener and Bonsienore 3-26 diversions in Scenario B. Again, slightly greater outflows are required in the dry season, resulting in slightly lower Lake levels, which then rebound to baseline levels during the wet season. CONCLUSIONS The foregoing analysis demonstrated that there is sufficient water supply in the Russian River system for City of Ukiah water diversions to approximately double from current levels up to 20 cfs in July. This water supply was projected to be available despite an estimated 26 percent decline in Eel River imports. Impacts on Lake Mendocino water elevations due to increased City of Ukiah diversions were estimated, on average, to be about one foot in September. (Figures 8 and 10). [t is likely that the simplifying assumptions made have overstated the potential impact of increased City diversions. The model assumes that an increase in diversion by the City, less an allowance for return flow, necessarily results in an effect on the Russian River. This is not the case. The future diversions are likely to be groundwater extractions with a corresponding lag time between extraction and the resulting streamflow depletion. The timing is important because if the actual depletion takes place in the winter, sufficient water will be available from sources other than lake releases to replace the extracted groundwater. While there will still be a stream depletion it will be less than the already small impact predicted by the model. The foregoing analysis also evaluated how Lake Mendocino and Russian River operations may be affected by the reduced Eel River imports. The analysis showed that demands downstream in the Russian River basin can be satisfied at historical rates (Scenario A), but at the expense of lower levels in Lake Mendocino during the dry season. Alternatively, it may be that historical Lake releases during the dry season were greater than necessary and can be reduced (Scenario B), resulting in less dry season impact to Lake levels. Figures 5 and 6 summarize the change from historical conditions attributable to reduced imports. This impact is the result of regulatory changes and is not the result of any action by the City. Prepared by Waenerand Bonsianore 3-27 This report identified the assumptions necessary to predict the impact of changes in Eel River imports. These are preliminary determinations for planning purposes based on the best information and analysis currently available. As additional, more accurate information becomes available, this report as well as the Urban Water Management plan it supports may be revised. The City has formally requested Sonoma County Water Agency to assist the City in developing computer models that will more accurately predict the impact of reduced Eel River diversions on the City's water supply and the water supply of upstream and downstream water users. It will take time to develop this additional analysis. The UWMP will be revised as additional and more accurate information becomes available.

Wells completed in the continental basin deposits produce water slowly because of consolidated, fine-Grained material and low permeability Well yield ran¢es from 1 - 50 allons per minute (gpm). The second unit is the continental terrace deposits situated mostly on the periphery of the vallev These deposits are relatively thin (up to 25 feet) have a low permeability and arc not a sienificant groundwater source. fhe third vallev fill unit is the Holocene alluvium consisting of uncemented gravel sand silt and clay deposited in the last 10,000 years The Holocene alluvium covers approximately 30 square miles throughout broad areas of the flood plain and more narrow bands alone the Russian River north of the Forks and along tributary streams It is Generally less than 100 feet thick but extends Prepared by Waener and Bonsienore 3_Zg up to 200 feet in depth. Consisting of coarse and uncemented sediments, the alluvium exhibits high porosity and permeability, thereby holding a significant quantity of water and transmitting water rapidly. Well yields range from 100 to 1000 gpm. fhe USES (Farrar 1986) reported that the "auantity of available ground water stored in the upper 100 feet of the most productive area of the valley fill ('type Il is estimated to be about 90 000 acre feet" The statement suggests that as much as 90 000 acre feet could be developed which is far in excess of the City's expected future demand. Groundwater in the alluvium is hydraulically connected to and interacts with surface flows The principal source of groundwater is infiltration of precipitation. Other sources contributing to Ukiah valley groundwater are streamflow leakage, deep percolation from irrigation and treated effluent discharged via the City of Ukiahpercolation ponds. "the groundwater table (the underground water surface) fluctuates seasonally being at its highest level in March or April at the end of the wet season, and at its lowest in October at the end of the drv season. Seasonal fluctuations range on the order of 5 to 20 feet Measurements have been taken and recorded over a long time period at a few wells in the valley Measurements were generally taken twice a year, at the end of the wet season and at the end of the drv season. The groundwater measurements show the water table rebounds during the wet season to about the same elevation in all but abnormall~rv years such as 1977. The water table rebounded completely in one year of normal precipitation. Water surface measurements over the long-term show no trend in groundwater levels. A 1986 USGS investigation (referenced below and attached) of groundwater levels in the Ukiah Valley found that, "None of the hydrographs show any prominent long-term declines. Water levels measured during the 1980's are remarkably similar to those measured during the 1960's and 1970's." Bulletin 1 18 of the California Department of Water Resources updated 2/27/04 in its section on the Ukiah Valley Groundwater Basin (referenced below and attached) states `Based on hydrographs from DWR monitored wells, groundwater levels in the past 30 scars have remained relatively stable. During drought conditions there is increased drawdown during summer months and less recovery in winter months. Post-drought conditions rebound to approximately the same levels aspre-drought conditions." Water Level in the Ukiah Valley WeWagner & Bonsi ng ore prepared Figures 1 through 4 (attached at the end of this chapter) which show water table h d}~r0 raphs through 2007 from the available record of long term monitoring of wells in Ukiah Valley. Figure 5 shows the location of those wells. The hydrographs show the seasonal fluctuation due to the precipitation, the effect of drought in 1977 and the absence of a long-term trend in water surface elevation. Because the alluvium contains and transmits water easily there is significant interaction between the Ukiah basin aquifer and the Russian River. Water level measurements show that in most years in spring the aquifer is full and spills to the river. At the southern end of the Ukiah Prepared by Wagner and Bonsignore 3-29 groundwater basin, the bedrock rises toward the surface and groundwater must move to the surface stream (Russian River) to move downstream. The predominant movement of water is from the Ukiah groundwater basin to the Russian River However conditions fluctuate and fesolt occasionally results in some water moving from the river to the aquifer When the river staee is high, water moves from the river into bank storaee, where it is temporarily held until the river staee falls and water drains back to the river. When the aauifer water table is low, as happens toward the end of the dry season, water moves from the river to the aquifer. This is compounded by the effect of phreatoRhytes (water-loving plants) drawing water from the aquifer. Finally, pumping of wells will cause a localized drawdown of the water table which can result in flow movine from the river to the a ug ifer• Responses to Comments from LAFCO dated October 4, 2007 Item l0. pa eg 6, City's Water Right Permit Extension, LAFCO writes that the "Cite Consumed a total of 4131 acre feet of water in 2004." The commenter has confused consumptive use with water production "fhe consumptive use of the City's diversions in 2004 (and proportionally for any other years is about 43% of the total amount diverted. As described in detail in the above report, return flows make a sie_nificant contribution~~to the hydrologic system. With respect to Items 11, 12, 13 and 14 we will consider these comments together and offer the following response: LAFCO's suggests that there exists the need for a groundwater basin study although the comments do not specifically address the areas of concern, offering instead a general concern that there ma be a roblem with water su 1 It also discounts the USGS and DWR Bulletin as outdated and based on inadequate data. The hydrographs that were evaluated by USGS in 1985 and by DWR in its Bulletin 118, updated in 2004, clearly show that eroundwater conditions in the valley have changed very little if at all. The wells with the loneest record that are readily available and included herein, which include draw-dewt3water level data up to 2007, show the same response today as they did in the past. The water level data is likely the most reliable information we have indicating the overall water supply health of the eroundwater basin. LAFCO cites a recommendation by Dr. Sari Sommarstrom, Ph.D. recommending a "specific ground-water study of the Ukiah Valley.., to determine the relative amounts of surface and groundwater currently used, irrigation recharge rates and movement, and the safe yield of the groundwater basin." Such a study as suggested by LAFCO mieht prove to be a useful investigation for future planning as part of a comprehensive reeional water mana eg ment program; but it is not necessary at this time in order to conclude that sufficient water supplies exist to continue the development of the City's water riehts. Runnoff into surface streams represent potential recharge to the Ukiah eroundwater aquifer Those streams include the East Fork Russian River, West Fork Russian River and uneaged tributaries to Ukiah Valley. The ungaeed tributaries include Hensley, Ackerman, Orrs Doolin Prepared by Wagner and Bonsignore 3-30 Robinson, Howard, Sulphur, McClure Howell, Morrison and 12 unnamed creeks "the drainage area of the uneaged tributaries is 137 percent of the drainage area of the West Fork Total flow of the ungaged tributaries can be estimated based on 137 percent of the West Fork flow To estimate streamflow entering Ukiah Valley from the East Pork in the future an adjustment was made to account for the effect of the FF,RC license ES condition constraint This adiustment had the effect of reducing future Fast Fork flows by 37 300 acre-feet per year on average Total surface flow entering the Ukiah Valley in the future, on an averaee annual basis can be estimated as follows.

In response to those letters, PGBE notiTied FERC staff at the Regional Otlfca of its intent to consult with both CDFG and NMFS to better understand their concerns. PGBE met with representatives of CDFG, NMFS, and the Round Valley Indian Tribes (RVIT) on September 7 and October 5, 2008 to discuss the new flow regime for the Project. After these meetings, PGBE reviewed all fbw records for the Project since the new flow regime was implemented in June of 2004. Based on that review, PGBE discovered that CDFG and NMFS were correct in their assertions, and also that additional errors had occurred in Implementing the flow releases. As the Senior Vie President of Generation for PGBE, i want to assure you that PGBE takes these implementatlon errors very seriously. PGBE already has taken a number of specHic actions to ensure its operations are in full compliance with the new (low regime, including providing additional operator training and instructions. Within the next 30 days, PGBE will provide FERG with a list of any additbnal corrective actions that may be appropriate. In fatal, there have been three types of errors: (1) overreleases in 2005 and 2008 that occurred during times when Cape Hom Dam was spilling water, due to the mistaken application of NMFS' Reasonable and Prudent Alternative (RPA); (2) overreleases that occurred in 2004, 2005 and 2006 as a reautt of PGBE's efforts to compy with the East Branch Russian River (EBRR) minimum flow requirements set forth in RPA Sectlon E.3; and (3) overreleases that occurred in the fall of 2004 as a resurt of PGBE's failure to make the required seasonal adjustments required by the RPA. Each of these scenarios IS discussed in turn below. A summary of the RPA Flow Requirements fs Included for reference in Attachment A. Uno£F1cia1 FERC-Generated PDF of 20061020-0025 Received by FERC OSEC 10/18/2006 in Docketk: P-77-000 _ ~ Honorable Magalie R. Sales October 16, 2006 Page 2 A Overreleaaes When Cape Hom Dam Was Spilling PGBE has determined that during periods when Cape Hom Dam was spilling in 2005 and 2008, PG&E misapplied the limitations set forth in Section E.5 and instead diverted water to the EBRR up to the maximum available tunnel capacity. The specific dates and amounts of the overreleases are set forth in Attachment B to this letter. PG&E's misapplication of the Section E.5 limitations during times of spill was wholly unintentional and stemmed from PG&E's erroneous reliance on the modeling. developed by the Department of the Interior (DOI) during the license amendment proceeding. Although the DOI modeling was Initially developed to support the flow proposal recommended by DOI and NMFS in response to FERC's draft environmental impact statement, NMFS also relied upon this modeling to develop its RPA. Thus, the assumptions of the DOI modeling are reflected In the final environmental Impact statement prepared by FERC as well as the final biological opinion prepared by NMFS. The DOI modeling assumed that dlversions to the EBRR during times of spill at Cape Hom Dam would be maximized to the full tunnel capacity. Specif iCaily, the instructions for the modeling described the assumptions as follows: It the sum of the accretion [between the Cape Horn and Scott dams) and the Lake Pillsbury release is greater than the sum of the Cape Horn Dam release and the tunnel diversion then sufficient flow is reaching Cape Hom Dam to meet the minimum flow requirements both for the Eel River below Cape Hom Dam and in the diversion tunnel. In this case, there is no need for additional flow releases from Lake PBisbury and the excess accretion is used to ti11 the diversion tonne! up to its capacity. The accretion fknv above the tunnel capacity is released at Cape Hom Dam. See Attachment C, "Generalized HydrologlclOperational Model of the Upper Eel River BasfrUPotter Valley Project," prepared for DOI by-the National Resources Consulting Engineers, Inc. at p. 13 (emphasis added). Although the modeling assumed that diversions to the EBRR would be maximized when Cape Hom Dam was spilling, the final language in RPA Section E.5 specifying maximum diversions to the EBRR did not incorporate an exception for spill conditions. Unfortunatety, when PG$E began implementing the RPA flows, personnel who had been Involved in the license amendment proceeding and familiar with the DOI modeling erroneously applied the modeling logic during periods of spill at Cape Hom Dam rather than folbw the limitations specifically set forth in Section E.5. The result is that PGB~E overreleased to the EBRR during times o1 spill in both 2005 and 2008. Based on its meetings with the resource agencies and RVIT, PGBE recognizes its error and has taken steps to ensure that operational personnel are fully Informed of the Unofficial FERC-Gene=aGetl PDF of 20061020-0025 Received by FERC OSEC 10/18/2006 in DocKet«: P-77-000 Honorable Magalie R. Salas October 16, 2006 Page 3 apparent discrepancy between the modeling and the language RPA in Section E.5. PGB~E will strictly adhere to the diversion limitations set forth in Section E.5 unless and until FERC and NMFS determine some modification is appropriate. B. Overreleases Resulting From PG&E's Efforts To Ensure Compliance With EBRR Minimum Flow Requirements In addition to the overreleases that occurred in 2005 and 2006 during times of spill, PG&E's recent review of its flow records has revealed numerous instances where the actual diversions to the EBRR exceeded the maximum diversions set forth in RPA Section E.S, as a result of PG&E's addition of a smal{ buffer to its EBRR releases to ensure that it fully met the minimum flow requirements set forth in RPA Section E.3. The specific dates and amounts of these overreleases are set forth in Attachment D. Whenever a license condition requires a minimum instream slow release, it is standard industry practice to release a small amount above the required minimum to ensure that the release does not fall below the minimum requirement. Following this standard industry practice, PG&E added a small buffer to the EBRR diversions (typically in the range of 10 cis) in order to ensure compliance with the minimum instream flow requirements set forth in RPA Section E.3. However, because the minimum release requirements in Section E.3 are defined in the same way as the maximum diversion limits set forth in Section E.5 (i.e., the EBRR releases set forth in Section C.1 plus the PVID releases), this practice of including a buffer in the EBRR diversions resulted in slight overreleases to the EBRR when the limitations of RPA Section E.5 applied (i.e. when Lake Pillsbury was below the Target Storage Curve). For example, if the maximum release under Section E.5 was 125 cfs, PG&E would release approximately 135 cfs in order to ensure it met the minimum flow requirement set forth in Section E.3. Had PG&E not applied this buffer, it would have run the risk of falling below the minimum flow requirements. In order to ensure that PG&E's future operations comply with the new flow regime, PG&E is seeking guidance from the Commission regarding which release obligation should take priority when Lake Pillsbury is below the Target Storage Curve -the minimum requirements set forth in RPA Section E.3 or the maximum limitation set forth in RPA Section E.5. PG&E also plans to consult with NMFS regarding the issue and will provide the Commission with any response it receives. C. Overreleases Resulting From PG&E's Failure To Make The Seasonal AdJustments Required By The RPA PG&E's review of its records also revealed that in the first year of implementing the new flow regime, PG&E failed to take into account the seasonal adjustments to the maximum flows to the EBRR required by Section E.S. The specific dates and amounts of the overreleases are set forth in Attachment E. Unofficial FERC-Genezated PDF of 20061020-0025 Received by FERC OSEC 10/18/2006 in DocketN: P-77-000 l Honorable Magalie R. Salas October 16, 2006 Page 4 Under RPA Section E.5, the maximum release to the EBRR when Lake Pillsbury is below the Target Storage Curve varies by season. From May 15 through September 15 the maximum release is 125 cfs; from September 16 through October 15 the maximum release decreases to 85 cfs; from October 16 through April 14 the maximum release decreases again to 40 cfs; and from April 15 through May t4 the maximum release increases again to 85 cts. Based on the flow records, PG&E failed to implement these seasonal adjustments in the fall of 2004. Accordingly, although the maximum release to the EBRR should have decreased from 125 cfs to 85 cfs on September 16, 2004, PG&E appears to have continued to release the 125 cfs maximum, while applying the approximately 10 cfs buffer described in the preceding section. PG&E did not repeat this error in 2005 or 2006. PGBE has retrained its operators on the seasonal variations and provided them with clear written instructions on how to implement them. Because of the wet winter that occurred in the winter of 2004/2005, PG&E does not believe the error in storage regulation in 2004 resulted in any negative environmental impacts. Lake storage began to exceed the Target Storage Curve on December 9, 2004, and remained above Target Storage Curve through March 14, 2005. Conditions after March 14, 2005 are discussed earlier in this letter and in Attachment B. PG&E acknowledges its compliance failure in relation to the issues described above and is committed to fully and accurately implementing the RPA. PG&E also acknowledges the Important role that CDFG and NMFS played in bringing this issue to our attention. Although the RPA sets forth a technically complex and challenging flow schedule to implement, PGBE takes responsibility and is accountable for these errors. PGBE prides Itself on its hydroelectric compliance record; the performance here simply fails to live up to PG&E standards, If you have any questions or concerns, please contact Randy Livingston, Sr. director - Power Generation at (415) 973-6950.

Summary of RPA Flow Requirements On January 28, 2004, FERC issued its Order Amending License for the Potter Valley Project. !n re Pacific Gas and Electric Company, 106 FERC ¶ 61,065. FERC's order adopted NMFS' Reasonable and Prudent Alternative (RPA), which contained several provisions for a new flow regime at Potter Valley. Appendix A of the Order Amending License contained numerous operating rules for Project flaws, including prescribed minimum and maximum flows to the EBRR under varying circumstances. Specifically, the RPA provided: C.1. Minimum flows of the East Branch of the Russian River, MF16, measured at the PGBE gauge E-16, but excluding flows released for the Potter Valley Irrigation District, shall be computed as shown in the following table: Minimum Flow of the East Branch Russian River Period Classification From Throu h Normal D Critical Se 16 A r 14 35 cfs 35 cfs 5 cfs A r 15 Ma 14 35 cfs 25 cfs 5 cfs Ma 15 Se 15 75 cfs 25 cfs 5 cfs ...., E.3. Release to the East Branch Russian River shall be greater than or equal to the minimum flow MF16 specified in Section C plus the release for the Potter Valley Irrigation District. ..... E.4. Release for the Potter Valley Irrigation District shall not exceed 5 cfs from October 16-April 14 and 50 cfs from April 15 to October 15. If CLP (April 1) is less than 25,000 ac-ft, this release shall not exceed 25 cfs during the following period from April 15 through October 15, .,... E.5. Diversions in excess of the sum of the minimum flow MF16 specified in Section C and the release to the Potter Valley Irrigation District specified in Section E.4 acan [sic] only be made when the Lake Pillsbury Storage is above the Target Storage Curve. Exceptions to the rule can occur only due to rate [sic] and brief emergency power and water demands. Thus, RPA Section E.3 defines the minimum flows to the EBRR that must be met throughout the year as the sum of the minimum flows set forth in RPA Section C.1 plus the releases to PVID. RPA Section E,5 defines the maximum flows to the EBRR when Lake Pillsbury is below the Target Storage Curve in the same way. Thus, based on the Uno£Flclal FERC-Generated PDF o£ 20061020-0025 Received by FERC OSEC 10/18/2006 in DocketN: P-77-000 flow schedules set forth in sections E.3 and E.4, in normal water years' the maximum diversions to the EBRR when Lake Pillsbury was below the Target Storage Curve should have been as follows: October 16 - A rii 14 40 cfs A ril 15 -May 14 85 cfs Ma 15 - Se tember 15 125 cfs Se tember 16 -October 15 85 cts I'he years _'004. 2005 and ?006 e'ere all classified as ne~rmal water years. vnofflcial FERC-Generated PDF of 20061020-0025 Received by FERC OSEC 10/10/2006 in DocketN: P-77-000 ATTACHMENT B Unofficial FERC-Generated PDF of 20061020-0025 Received by FERC OSEC 10/18/2006 in Docketll: P-77-000 Attachment B.

County of Sonoma are very concerned about the chaztges in flows into the Russian River watershed from the Potter Valley Project instituted by PG&E beginning in the fall of 2006. These flow changas have adversely affected water storage levels in Laka Mendocino, to the point where predicted storage in Laka Mendocino may fall to unprecedented low levels in late summer altd early fall, with potentially catastrophic impacts to threatened Chinook salmon within the Russian River. The Agency is taking action to attempt to mitigate the impacts of PG&E's changes in Potter Valley Project operations and preserve fall storage in Lake Mendocino. These actions include requesting and receiving authority from the State Water Resource Control Board to temporarily reduce Russimt River minimum instreatn flow requirements, and working with the Agency's customers and other water users to implement additional water conservation measures. As discussed in our meeting, PG&E implemented the changas iu Potter Valley Project operations,-which critically reduced Lake Mendocino storage, without consulting with or informing the Agency ol• the County. The Agency and the County still do not know how PG&E is operating the Project, or whether operating the project using other ct•iterion that is also coitsistent with the existing Federal Energy Regulatory Commission (FERC) license could have resulted in higher Lake Mendocino storage, Although Potter Valley Project diversions to the Russian River watershed are critical to the Russian River fishery and to the region's water supply, PG&E changed those diversions without analyzing the impact of the changes on these interests, and without notifying or discussing the impact of the changes with those impacted by the changes, We ware encouraged to hear at the May 17, 2007 meeting that PG&E is now willing to provide information about Project operations to the Agency, and to include the Agency ht future meetings regarding project operations. At the May 17, 2007 meeting, you requested, and we agreed to provide, specific detail about the types of information and arrangements requested,by_the Agency,_Those details are attachgd._. - . _ _. _ ._ P.O.

We believe that agreement requires a fid] sharing of information with the Agency, and fiill participation by tho Agency in ongoing discussions about A•oject operations, Moreover, as noted in our meeting, the Agency has significant expertise in the areas of hydrology, modeling, engineering, and fisheries biology, and is willing to use that expertise to work with PG&E and other stakeholders to maximize the benefit ofthe Project for both Russian River and Eel River interests. Since the impact of the 2004 FERC license amendment on flows into the Rnssiau River watershed is in reality much greater tlrarr anticipated, we are looking forward to working with PG&E to explore with National Marine Fishery Service what flexibility exists within the current license to correct these issues and, if needed, what the process would be to gain their support for any necessary modifications to the license. We look forward to a prompt response to our requests. If you have any questions about the requests, please call Chris Murray at (707) 547-1925.

Poole General Manager/Chief Engineer Sonoma County Water Agency . 404 Aviation Boulevard Santa Rosa, CA 95403 Re: Potter Valley Project, FERC Project No. 77 Response to Sonoma County Water Aoency Letter dated June 8 2007 Dear Mr. Poole: Thank you for your June 8, 2007 letter concerning Pacific Gas and Electric Company's Potter Valley Project. As we discussed in our May 17, 2007 meeting with you, National Marine Fisheries Service. (NMFS) and representatives of the Sohoma County Board of Supervisors, PG&E is committed to working with your agency and other East Branch Russian River (EBRR) water users to try to minimize water supply impacts, while still complying with the mandatory conditions of the Potter Valley Project operating license issued to PG&E by the Federal Energy Regulatory Commission (FERC). We realize how important the water the Potter Valley Project diverts from the Eei-River into the EBRR is fo the beneficiaries of this water. That's why, when it was brought to PG&E's attention by the California Department of Fish and Game and the NMFS in 2006 that the water diversions we were making to the EBRR were greater than what is allowed under the license amendment issued by FERC in 2004, and we realized we would need to modify operations to comply with the conditions of the license, we analyzed the impacts and immediately began communications with your agency, other water users, local elected officials, and the media to advise of these changes, , As we reviewed with you and other EBRR water users in November 2006, the reduction in diversions from the Eei River Into the EBRR required by the license amendment was considerably greater than what had been anticipated during the amendment proceeding and what was initially implemented by PG&E, As discussed with you and presented in detail at a November 2006 meeting with the Potter Valley Irrigation District attended by members of your staff, the average annual reduction in diverted water resulting from compliance with the license amendment is forecast by PG&E to be approximately 33% rather than the 15% that was anticipated during the amendment proceeding and in the NMFS Biological Opinion used by FERC in its order amending the license. Mr. Randy 4. Poole June 22, 2007 Page 2 Your letter included a list of information and coordination requests related to the Potter Valley Project. As you know, Protect flow information has been made publicly available on a daily basis via the Internet since March of this year. Additionally, for many years now, PG&E has provided your agency with daily telephone reports regarding key Project operational data such as water elevation and storage (n Lake Pillsbury, water releases and spill from Lake Pillsbury and Van Arsdale Reservoir, and water flow through Potter Valley Powerhouse. We will continue to provide your agency with this operational information, plus we will review the list of additional information you have requested and will respond separately. The list of information and coordination requests also asked that PG&E provide Sonoma County Water Agency with a right of first refusal on the sale of the Potter Valley Rroject. While we appreciate your interest in the future of the Potter Valley Project, PG&E has no current plans to sell the Project and does not see a right of first refusal as feasible. Again, PG&E fully recognizes the importance of Potter Valley Project water diversions to EBRR water users. We look forward to continuing to work with your agency and others to try to minimize the impact ofgreater-than-anticipated reductions in these diversions resulting from operating the Potter Valley Project in compliance with the Project license.

The collection system fox the City and UVSD consists of gxavityr pipes that range Erom 6 inches to 42 inches in diameter. The total length of gravity pipe is approximately 67 miles. boost of the collection system is served by gravity, however, nvo areas on the east side of the City require pumping stations- to convey the Elow to the gravity sewers. The age and condition of the Cin~'s sewer collection system varies by location. d portion of the collection system in the downtown uca was installed in the 1890x. Appxo.Yimately one-half of the City's collection system was installed before 1957 and 90 percent was installed before 1977. Wastewater Treatment System. Construction of the original WWTP was completed in 1958. The original plant consisted of a hcadworks facility (one baxminutor and four influent pumps), pre-aeration grit tanks, one primary clarifier, one trickling filter, one s-econdaxy clarifier, a chlorine contactor pipe, two anaerobic digesters, two oxidation ponds ox evaporation/percolation ponds, and two sludge lagoons. The original plant capacity was 2.5 mgd average dm weather Elow (ADWF~ with a peak wet weather flow of 10.5 mgd. Discharge was to die Russian River. The design organic and solids loadings were 5,400 pounds per day (Ib/day) and 5,400 lb/day, respectively. 1'he North Coast Regional Water Quahty Control Board (Regional Water Board) of California modified discharge xequuements in 1974 to allow only seasonal (October 1 through May 14) discharge to the Russian River at a discharge rate of one percent of [he river flow. Flow above one percent of the Russian River Elow between these dates and all flow from Mav 15 through September 30 is disposed of by a combination of evaporation and percolation Ezom the ponds and by reuse of treated effluent onsite. In 1983, the plant capacity was increased to 2.8 mgd ~1llWF with a maeimum wet weather Elow discharge to the Russian River of 7.0 mgd. The improvements included conversion of the secondary clarifier into a second primary clarifier, construction of a biological tower in addition to the trickling filter, three new secondary clarifiers, a new chlorine contactor pipe, new dechloxination facilities, addition of emergent}' generator facilities, and a new direct outEall. Tn addition, an earthen levee was constructed around the \X/\X/TP site and sludge lagoons at an elevation of 580 feet MSL to protect against the ] 00-year Flood level. In 1986, a third evaporation/percolation pond was constructed to the north of the two existing ponds, and in 1989, an effluent pumping station was constructed to transfer secondary effluent to the third pond. dlso in 1989, the Regional Water Board revised the Basin Plan to require advanced wastewater [reatment (A\X/'I) of the effluent discharged to the Russian River. Secondary treatment was also required Eor discharge to the ponds. In 1995, the barminutoxs in the headwoxks were replaced with channel screen comminutoxs, and a fourth secondary clarifier, a new A1&"F system, and a new solids handling facility, including a belt filter press fox processing solids, were arnstmaed. Currently, the City's \VW'I'P discharges treated effluent under the National Pollutant Discharge Elimination System (NPDES) Permit No. CA0022888 issued b}' the Regional Water Board. Two discharge points axe permitted as described above, one to [hc Russian River and the other to the dace ponds. Figure 42 is an aerial view of the \y/\y/'I'P.

Potential publicly owned xecpded water sites within and near the City include the Ckiah Municipal .lirpoxt, Highway 107 median, Ckiah Golf Couxsc, city parks, schools, Anton Stadium, City's softball complex, City Civic Centex, Cii}~ and County Faixga~unds, and Mendocino College. Potential privately owned xecyde water sites include vineyards and ozchaxds. The estimated acreage of land that could be irrigated from publicly owned sites is approximately 23G acres. There axe not sufficient publicly owned facilities for use of all the recede water and any xecycied water program would require the participation of pxivately owned facilities The likiah Municipal dixport and Highway 101 median arc located close to the WVG'TP site and arc the most feasible sites- fox recycled water. Mos[ of the other sites are located hr the northern part of the City, while the ~~C/W-1'P is located in the southern part of the Cit}~. This makes the cost to use recycled water significantly higher. Privately owned facilities such as vineyards and orchards are the most likely users of recvded water. However, significant barriers were identified when local farmers and aexicultuxal indus[rv representatives were consulted. These barriers could limit the feasibility of a recycled water pxogxam fox privately owned facilities. 'these barriers include the following: 1) seasonal recd for water does not necessarily correspond with rimes when recvded water is most available, thus requiring additional storage facilities, 2) for organic farmers, the thought is that the use of receded water would remove the organic certification from their products, 3) pxivately owned facilities fear the possibility of losing their existuxg water rights iE recvded water is used, 4) existing water supplies appear to be sufficient to meet their needs, and S) it is not cost effective to use recycled water without subsidizing the xecyde water program. To fully implement a water recycle pxogxam these barricss will need to be addressed through public education rogran.~ Tables 4-4, 4-5, and 46 list the actual, potential, and predicted recycled water use within the City. . ~ ~ Uaertype TreatmerttLwN 2005 2010 ~ .. - 2015 2020 2025 2030 Agriculture Tertiary 0 0 tbd' tbd' tbda tbd' Landscape Tertiary 0 0 tbda tbd' tbd' tbda Wildlife Habitat 0 0 0 0 0 0 Wetlands 0 0 0 0 0 0 Industrial 0 0 0 0 0 0 Groundwater Recharge 0 0 0 0 0 0 Consumptive Reuse within Plant Tertiary 8° 323° 323" 323° 323° 323° Golf Course Irrigation 0 0 tbd tbd tbd tbd Total Potential Recycled Water g 323 3,843 4,262 4,682 5,101 a The uses for recycled water have not been determined The fatal amount will be divided amongst these uses. ~ This quantity o(flow reused at the plant is not measured It is a relatively small quantify Estimated use orplanf water within the WWTP property boundaries. 4-5 DRAFT for review purposes only.

However, because of the dWT treated effluent total rnttogen concentration, vineyard owners may have some reservations regarding such reuse. :~Isq the Ukiah Valley has a high percentage of organic farmers. At this time, organic Eaxmers- may fear losing their organic certification if they use recycled water. Water Rights. Some farmers have expressed concern that use of mcycled water in place of their current water supplies could jeopardize surface water rights. However, California Water Code Section 1010 provides that no claim of water right (cipaxian, pre-1914 appropciative, post-1914 appxopriadve) will be reduced ox lost as a result of the use of xecvcled water, and drat the us-e of cecycled water in lieu of surface water is equivalent to maintaining that right and shall consdmte beneficial use.

HISTORICAL AND PROJECTED WATER USE Water demand projections provide the basis Eor sizing and staging Eumre water facilities. Water use and production records, combined with projections of population, employment, and urban development, provide the basis for estimating future water requirements. Phis chapter presents an analysis of available demographic and water use data, customer connections, historical groundwater and surface water production, unit water use, and the resulting projections Eor future water needs fox the City. 5.1 Employment, Land Use, and Population The following paragraphs discuss the employment characteristcs-, land axe characteristics, and population projects. Employment Characteristics. Industry employment in Ukiah and the surrounding area is provided largcl}' by the local hospital, retail, and service industry. Agriculmxc also is a major cmplo}'ex in Mendocino County. Industries include wineries, vineyards, pear orchards, and wood products. The number of small non- agricultural types of manufacmxexs and service industries continue to rise, while timber industry activities are in decline. As with many coral communities, state, county, and local government agencies also constitute a significant part of local employment (L"kiah Chambers of Commerce htt~//u>tvw.ukiahchamber.com/demographics html). Land Use Characteristics. Land use within the Cit}' region is characterized as- suburban. Additional land uses in the region and service area indude agriculture, light industrial, commercial, and recreational. Land use within the Russian River watershed is primarily agricultural with the greatest emphasis on vineyards, livestock, and orchard crops. Major orchard crops consist of apples, pears, and pmnes, wlvle some production of other crops such as cherries and walnuts also occur. The Russian River watershed contains both dry and irrigated pastures, with both hay and grain grown (Ukiah Chambers of Commerce http://www.ul:iahchamber.com/demo¢~anhics html). Population Projections. Ukiah has experienced slow population growth with a 2.9 percent total incxeas'e between 2000 and 2004. In 1995, the General Plan estimated an average annual growth rate of 4.5 percent. More recent data from the California Department of finance indicates an average annual growth rate of 0.77 percent from 1999 to 2003. For the fumxe water production anah~sis, an annual growth rate of 1.0 percent was assumed in die population projections in the Cit}'~ Build-out fox the City is- expected in 2015 at a population of 17,992.

Records of historical water production obtained from Bartle Wells Associates serve as the basis Eor developing unit water demands Eor the City. The City recent]}' restructured i[s water rate schedule and is- also updating its accounting system.

Current City accounting practices do not identify separate account types such as single family residential, multi-family residential, industrial, institutional/commercial, or landscape. The number of connections was projected based on the average number of people per connection Exom years 2002 to 2004. It was assumed that the Cit}' would begin annexing land within its sphere of influence in 201 ] and that dtis process would span 20 wars. This- is reflected in 'fable 5-2 through 5-4.

The per capita demand of 228 gpd is relatively high but not out of line for similar communities given the warm summer climate and degree of landscaping. However, a[ rimes, the City has a difficult time meeting demands, especially peak demands during extended periods of hot weather. The reason the City's water system cannot meet the peak water demands dosing these periods is- because the pumping capacity of dxe existing Ranney collector, surface water wells, and percolated groundwater well is limited. dlso, during drought conditions, the water table is lower, which reduces the yield of the wells. The City is conducting a groundwater well siting study ro increase groundwater well production by 1,500 gym to help the City meet its peak demands. I Iowever, additional pumping capacity will be needed to meet future growth within the E=ii~'s-sphere of influence depicted in Figure 2-2. 5-5 DRAFT for review purposes only.

DEMAND MANAGEMENT PRACTICES Water conservation is a method available to reduce water demands, thereby reducing water supply needs fox the City. This chapter presents a description of the City's water conservation program, an economic analysis of water conservation Demand Management Measures (DMMs) 1, 2, 6, 14, and a description of the methods and assumptions used to conduct the analysis. 7.1 California Urban Water Conservation Council 'Che unpredictabihn of its water supplies and ever increasing demand on California's complex water resources have resulted in a coordinated effort by ll\X/R, water utilities, environmental organizations, and other interested groups to develop a hst of urban water conservation llMMs fox conserving water. "Phis consensus- building effort resulted in a Memorandum of lindexstanding (MOU) Regarding i;rban Water Conservation in CahEoxnia, as amended September 16, 7999, among parties, which formalizes an agreement to implement these DMMs and makes a cooperative effort to reduce the consumption of California's water resources. The DMMs as defined by the MOU axe presented in Table 7-1. The MOU is administered by the California Urban Water Conservation Council (CUWCC). 1'he City is not currently a MOU s-ignatox}'. 1'he MOU requires that a water utility implement only the llMMs that axe economically feasible. IE a DMM is not economically feasible, the utility may request an economic exemption for that DMM- 'Che DMMs as defined in the MOC are generally xecogrrized as standard definitions of water conservation measures.

DMM 4. 7- 8. 11. and ^^^"m,~' r12 are not analyzed because they axe cusentiy implemented; DMMs 5 and 9 axe not analyzed because the City has very limited lazge landscape, commercial, industrial, and institutional customers. DMM 10 is not analyzed because the Citv is not a wholesaler. Assumptions used in the economic analysis fox each DMM analyzed are described in Appendix 1'. llicecdy beneath each assumption is a brief description of the rationale and/or supporting evidence for that assumption. Common assumptions Eor all DMMs axe that the value of conserved water is $1,206/<\F, the real discount rate is 6.15 percent, and the overhead rate is 13 percent The teal discount rate is calculated from the assumed real cost of mone}- (8.67 percent) and the assumed long-term inflation rate (252 percent) using the precise conversion method (A&N'I'echnical Services- 2000, pgA-2). The economic analysis was performed using Micxosoft® Excel 2003, a spreadsheet program. A separate, customved worksheet fox each DMM is presented in Appendix F. F.ach DMM economic analysis spreadsheet calculates, on an annual basis, the number of interventions and the dollar values of the benefits and costs that would result from implementing a particular DMM.

The November 2005 xa[e of $0.91 per 748 gallons (see Table 7-3) was used plus $2,471 per million gallons to treat the water when it becomes wastewater. Because 80 percent of treatment cos[s axe attributed to flow, only 80 percent of the cost to treat the wastewater was used. The remaining 20 percent of the wastewater treatment costs aze associated with organic and solids loading. "]'his equated to a total value of water of $1,206 per acre-feet. "]'his calculated value fox conserved wa[ex does not include die capita] cost fox improvements to the wastewater [ceatment plant to recede all of City's wastewater in the future iE the City is not allowed to discharge into the Russian River. Based on the total annual wa[er savings calculated, it is estimated that the City mac be able [o reduce the design flow for future wastewater treatment needs by 6 percent. 73 DRAFT for review purpazes only.

Schedule: "1'he City has offered water savings kits in the past. However, due to lack of interest by customers, the Ciry has discontinued this pxogxam. Evaluation of DMM Effectiveness: The City offers xetxoflt kits iE requested by the public, but has not seen significant savings as a result from these kits. Table 7-4 summarizes the economic analysis Eox this DMM. The benefit to wst ratio is 3.4. See Appendix F fox full economic results Eox this DMM. DMM 3 System water audits leak detection and repair. Description: A system water audit, leak detection and repair pxogxam consists of ongoing leak detection and repair within the system, focused on the high probability leak areas. "Phis also includes an ongoing meter calibration and replacement program for all production and distribution meters. Schedule: The Ciry performs leak detection and repair on an ongoing basis. The Ciry, also, calculates system water losses annually and reports this information to D\X/R. In addition to calculating system losses, the City is currently replacing old meters in the system. The new meters will provide a more accurate reading of water use within the Citv. Evaluation of DMM Effectiveness: The City's annual report to DWR tracks the unaccounted for water Losses in the system. Anc reductions in water loss due to the replacement of old meters and water leak detection and repairs will be reflected in the annual report "I'he City does not record the number of miles of distribution lines surveyed, nor the expenditures. Tlils DMM is non-quantifiable and therefore, no results are provided in the economic analysis. DMM 4 Metering with commodity rates for all new connections and retrofit of existing connections. Description: The Ciry water distribution system is fully metered. The City is currently replacing old meters in ehe system in an effort to provide more accurate readings- of water use within its service area. Schedule: The Citv will continue to install and read meters on all new services and replace aging meters. Evaluation of DMM Effectiveness: F.Efectiveness of this DMM wIll be evaluated by comparison of prior water use to future water use. However, the City does not record the number of meter retrofits, me[exed and unmetexed accounts, nor the number of accounts without commodity rates. The City recently went through a rate xe-structuring that is believed will reduce water uses in the future.

Description: 'l'he high-efficiency washing machine rebate pxogxam would consist of distributing rebates to those customers who purchase a water conserving washing machine. Schedule: 1'he City does not currently have a high efficiency washing machine rebate program. Evaluation of DMM Effectiveness: Effectiveness of this llMM is not evaluated because the City- does not track the number of rebates. Table 7-4 summarizes the economic analysis Eox tits DMM. The benefit to cost ratio is 0.4. See Appendix E for Eull economic results Eox this DMM. DMM 7. Pubfic information programs. Description: pubhe information programs would consist of conservation news articles, fliers, media coverage, community events, etc. Schedule: The City believes public awareness of water conservation issues is an important factor in ensuring a reliable water supply. The City promotes public awareness of water conservation through occasional bdl smffecs, distribution of the Consumer Confidence Report, radio broadcasts, and the City web-site. In addition, Cih- staff discuss with atstomexs how the}' can conserve water. Evaluation of DMM Effectiveness: Savings from this pxogxam cannot be dirccdy quantified. "I'he activities pexfoxmed in this program fall under the conservation budget fox the Ciro. The conservation budge[ is $12,000. DMM S. School education programs. Description The City would prepare water conservation programs to target children at school. Schedule: The City offers local schools tours of its water treatment plant and also provides educational materials. Eoux science classes on pubhe water supply a[ [he high school axe offered once a yeaz. The cost of this pxogxam comes out of the City's conservation budget. Evaluation of DMM Effectiveness: Savings from [his program cannot be directly quantified. DMM 9 Conservation programs for commercial industrial and institutional accounts. Description: The City would develop a conservation program fox CIl accounts that includes water audits targeted to the top water users. 'flits program would include surveys of past pxogxam participants to determine if audit recommendations were implemented. This program would also include incentives related to [he use of efficient: wateo-use technologies. Schedule: The City' has only two industrial customers: Maverick Industries and Red Tai1:11e Brewery. The City surveys the water usage of these industries. tiny new commercial, industrial, ox institutional developments will be reviewed by the City Planning Department and must meet all requirements of the Municipal Code. Due to the lack of CII accounts, this DMM has not been economically analyzed. 7-6 DRAF t for review purposes only- P'1728000~128619-Ukah UWMP'Drefl Report-AUousi 200TDrafl UWMP f101220071.do '. 7: Demand Management Practices 2005 Urban Water Management Plan DMM 10. Wholesale agency assistance programs. Description: ~R7holesaler water suppliers would provide Einanual incentives, or equivalent resources, as appropriate, beneficial, and mutually agreeable to their retail water agency customers to advance water conservation efforts and effectiveness. Schedule: This DMM is not apphcable to [he City since it is not a wholesale agency. DMM 11. Conservation pricing; Description: Conservative pricing requires that water sates encourage conservative water use by all customers. Schedule: The Ciro recently increased and xe-structured its water rates to encourage more conservation, see Table 7-3. The City has simplified its rate structure by elixninafing rate codes and classifying customers according to their meter size. The new rate structure incorporates the American A~'ater AA'oxks .Association (AWWA) demand capacity guidelines so that price increases across meter size in proportion to the potential demand a customer can place on the water system. Evaluation of DMM Effectiveness: Effectiveness of this DMM will be evaluated by comparison of Ciry water use prior to and following the implementation of conservation pricing. Because the City has just implemented a new rate schedule, the effectiveness can not be evaluated. DMM 12. Conservation coordinator. Description: A amservation coordinator is an ongoing component of a City's water conservation program. 1'he conservation coordinator would be responsible for implementing and monitoring a City's water conservation actinides. Schedule: In practice, all staff members- encourage water conservation implementation. Water conservation coordinatlon fox the Ciro is established by the policies determined by the City Council and includes answering questions of the pubhc by maintenance and meter readers while in the field. Evaluation of DMM Effectiveness: AA'ater savings from this llMM cannot be directly quantified. Effectiveness of this DMM will be evaluated by the success of the Cittr's water conservation program. DMM 13. Water waste prohibition. Description: AA'ater waste prohibition will require the City [o adop[ its Dian set of wa[ex conservation regulations. Schedule: 'I1~e City has adopted regulations that state in part "AX/here negligent ox wasteful use of water exists on a customer's premises...the City may discontinue the service..." (City Municipal Code Article 7, Section 3571). The Ciry fast sends cus-tomexs a letter calling their attention to the wasteful practice and asking fox correction. If the condition is not corrected within five days after the written notice, service may be discontinued if necessan-. Evaluation of DMM Effectiveness: Water savings from this program cannot be directly quantified. DMM 14. Residential ULFT replacement pro>rams. Description: Since October ]992, the sale of toilets using more than 7.6 gallons per flush has been prohibited by State and Federal regulations. "I'he residential ULFT replacement program will reyuixe the City to hand out rebates- to those who buy an ULF-1' toilet.

Sec Appendix F for full economic results fox this DMM. 7.4 Economic Analysis Results An estimate of esisting conservation savings is not available. It is likely drat previous and ongoing conservation measures have cesuleed in water savings of approximately 2 to 5 percent of [otal water production. The water savings already achieved by esisting conservation measures will have some impact on the City's ability to further reduce demand. Nevertheless, the City anticipates achieving additional water savings by further implementation of DMMs in the future. Of the four DMMs analyzed, three appear to be cost effective fox the City. DMMs 1, 2, and 14 should be evaluated in the future to assess if the Cit}r has the capital to implement them.

These costs do not account for recycled water pumping, wlilch could add savings of about $5,250 per year on energy if energy costs $0.14 per kilowatt/hour. The City may also chose to run these programs on a less aggressive schedule to reduce the capital costs- during the first Ecw years. "I'he ULPT toilet replacement program saves the City the most water. Duc to natural attrition, many toilets will be replaced in the future even without a rebate program. The results of this economic analysis arc similar to the results of other economic analyses conducted Eor cities of similaz population. 7.5 Non-quantifiable DMMs Because the water savings from DMMs 3, 7, 8, I1, 12, and ]3 axe not quantifiable, an economic analysis was not completed. The schedules and implementation strategies must be determined by the City based on information provided in the MOL' ro determine the best water conservation practices.

The low-lying regions of the Ukiah and Redwood Valleys as well as those sloping areas along the valley edges that include Quaternary- and Tertiary-age sediments define the areal extent of this north-south trending basin. The basin surface elevation varies from approximately 1,000 feet in the upper portions of the Redwood Valley, to approximately S00 reef in the lower, southern areas of the Ukiah Valley. The Russian River traverses the entire length of the Ukiah Valley groundwater basin and is met by many tributaries from both the east and west sides of Redwood and Ukiah Valleys. The main tributaries include Fotsythe Creek, which joins with the Russian River north of the city of Calpella, and the East Fork of the Russian River, which joins the main branch of the Russian River north of Ukiah. Lake Mendocino, a reservoir created from the East Fork of the Russian River located between Redwood Valley and Ukiah Valley, is also an important feature of the surface hydrology of the region. Precipitation in the basin ranges from approximately 45 inches in the north to about 35 inches in the south. Ukiah is the largest city within the valley and is located on its southwest side. Other cities include Talmage, east o£ Ukiah, and Calpella on the south end of Redwood Valley. Highway ] Ol travels the length of the Ukiah Valley from the south and veers west away from Redwood Valley, paralleling Forsythe Creek. Highway 20 enters the valley from the east and intersects with Highway 101 at Calpella. Hydrogeologic Information Water Bearing Formations Groundwater-bearing units of primary importance within the Ukiah Valley Groundwater Basin include Recent alluvium, as well as alluvium of Pliocene and Pleistocene age. The terrace deposits and dissected alluvium of Pleisocene age are of lesser importance with regard to groundwater production. Underlying these deposits is moderately to highly fractured basement rock consisting of the Franciscan and Knoxville Formations. Even when highly fractured these formations have limited permeability, and are considered to yield only small quantities of water locally (Cardwell 1965). Information on water-bearing formations, hydrogeology, and storage capacity is available from Cardwell (t965), DWR, (1965), and Farrar (1986). Recent Alluvium. Alluvium within the basin is considered a principal source of groundwater and consists of unconsolidated gravel, sand, silt, and Cal'rfomia's Groundwater Bulletin 118 Last update 2/27/04 North Coast Hydrologic Region Ukiah Valley Groundwater Basin minor amounts of clay deposited in channels and on floodplains of the Russian River and its tributaries, on alluvial fans, and as colluvium on interfan slopes. A subdivision of Recent alluvium includes river-channel deposits defined by those areas where gravely stream channel deposits are currently being deposited. River-channel deposits are generally very high yielding loose gravels and sands; in some cases these deposits contain boulders. Recent alluvium is thickest in the central portion of the basin and extends from the surface to depths of 50 to 80 feet (Cardwell 1965). An average specific yield of 20 percent was used for the alluvium in two separate studies (Cardwell 1965, DWR 1965). Groundwater in the alluvium generally occurs under unconfined conditions. Pleistocene Terrace Deposits. Terrace deposits are characterized as alluvial deposits of primarily Pleistocene age, ranging from a thin veneer of red gravelly clay soil, to deposits of sandy or silty gravel up to 200 feet thick. Terrace ii?nncits oenerally overly the PhOeene- and.PlelstOCene-aCe allnVlum , ____o_ and occur discontinuously along the flanks of the Ukiah Valley and more continuously within the Redwood Valley on both sides of the Russian River. Groundwater in the terrace deposits is unconfined to locally confined (Cardwell 1965). Production from the terrace deposits is variable based on sediment thickness, depth to water, and percentage of fine grained material; however, dtese deposits generally yield enough water for domestic purposes if an appreciable thickness of the deposit occurs below the water table (Cardwell 1965). Pliocene/Pleistocene Alluvium. These deposits are described as continental deposits comprised of poorly consolidated and poorly sorted clayey and sandy gravel, clayey sand, and sandy clay. In general, thick lenses of moderately indurated gravel interfinger with large bodies of blue sandy silt and clay (Cardwell 1965). Overall, this alluvium has low permeability due to the relatively high percentage of fine sediments; however, wells can produce moderate amounts of water from these sediments if long sections of perforated (or screened) intervals are used. Bed thickness is variable, with the maximum thickness considered to be about 2,000 feet. Outcrops of this formation can be seen along the entire east side of the Ukiah Valley, as well as the southeast side of the Redwood Valley (Cardwell 1965). ]t is pussible that current groundwater use relies more heavily on Pleistocene- and Pliocene-age alluvium than reflected in this basin description due to ongoing trends in improved well construction techniques and deeper well seal requirements. Groundwater in the older alluvium deposits is generally confined (Cazdwell 1965). Dissected Alluvium. Dissected alluvium is gravelly sediment cemented by carbonate precipitation located along Sulfur Creek below Vichy Springs and along McNab Creek. These sediments yield only very limited quantities of water (Cardwell 1965). California's Groundwater Bulletin t 18 Last update 2/2711M North Coast Hydrdogic Region Ukiah Valley Groundwater Basin Groundwater Level Trends Based on hydrographs from DWR monitored wells, groundwater levels in the past 30 years have remained relatively stable. During drought conditions there is increased drawdown during summer months and less recovery in winter months. Post-drought conditions rebound to approximately the same levels as pre-drought conditions. Groundwater Storage Groundwater Storage Capacity. It is estimated that approximately 324,000 of of storage exists in the older continental deposits; however, it is probably not usable for short-term storage purposes due to the low-permeability nature of these deposits (DWR 1965). Groundwater in Storage. Groundwater in storage within the alluvium and younger rF,-race deposits is estimated to be about 75,000 to 100,000 of (Cardwell 1965).. Groundwater in storage within the river-channel deposits between 10 and 50 foot depths is estimated to be 35,000 of based on an average specific yield of20 percent (Cardwell 1965, DWR 1965). Farrar (1986) estimated that the quantity of groundwater stored in the upper 100 feet of the most productive area of valley fill (Type I) to be about 90,000 of using an average specific yield of 8 percent and an azea of 20 square miles. Farzar (1986) also estimated the quantity of groundwater stored along the margins of the valley (Type II area) and underlain by terrace deposits or thin alluvium at 45,000 af. This estimate is based on the upper 100 feet of Type II aquifer materials, an area of 19 squaze miles, and an average specific yield of 5 percent. Groundwater Budget (Type C) There is not enough data available to provide an estimate of [he basin's water budget. Groundwater Quality Characterization. Water quality is good in general, especially water derived from Recent alluvium deposits; however, locally the content of chemical wnstituents varies widely. Overall, water is moderately hard to hard bicarbonate. Based on limited data, calcium-bicarbonate groundwater occurs in the southern portion of the basin and magnesium-bicarbonate water occurs in the east-central portion of the basin (Cardwell 1965). Quality in the Recent formations is similar to Russian River water, with slightly higher TDS and chloride levels. Pliocene- and Pleistocene-age formations yield water with higher TDS and sodium than Recent-age formations. Water from springs ranges ftom highly mineralized to good in quality (Cardwell 1965). TDS values range from 108 to 401 mg/L and average 224 mg(L based on four wells (Cardwell 1965). Electrical conductivity ranges from 450 to 759 µmhos.cm and average 605 µmhoslem based on two wells (Cardwell 1965). Based on analyses of 22 water supply wells in the Ukiah Valley, TDS ranges From 87 to 301 mg/L and averages about 166 mg/L. Impairments. Wells with high boron concentrations are located in several areas along the Ukiah Valley edges and in the north end of the Redwood California's Gnwndwater Bulletin 118 Last update 1127104 North Coast Hydrologic Region Ukiah Valley Groundwater Basin Valley. Verbal reports indicate that (in general) poor quality water occurs on the west side of the basin. Flammable gas was reported in at least one well. Pressurized carbon dioxide gas was detected in two wells which probably penetrate bedrock (Cardwell 1965). Most poor quality water is believed to migrate into basin sediments from basement rock through fractures or fatdts.

I Nerrp Coos[ MydrolnaK Region Description of the Region The North Coast HR covers approximately 12.46 million acres (19,470 square miles) and includes all or portions of Modoc, Siskiyou. Del Norte, Trinity, Humboldt, Mendocino; Lake, and Sonoma counties (Figure 25). Small aeeas of Shasta, Tehama, Glenn, Colusa, and Mario counties aze also within the region. Extending from the Oregon border south to Tomales Bay, the region includes portions of four geomorphic provinces. The northern Coast Range forms the portion of the region extending from the southern boundary north to the Mad River drainage and the fault contact with the metamorphic rocks of the Klamath Mountains, which continue north into Oregon. East of the Klamath terrane along the State border are the volcanic terranes of the Cascades and the Modoc Plateau. In the coastal mountains, most of the basins are along the narrow coastal strip between the Pacific Ocean and the ragged Coast Range and Klamath Mountains and along inland river valleys; alleviated basin areas are very sparse in the steep Klamath Mountains. in the volcanic terrane to the east, mast of the basins are in block faulted valleys that once held Pleistocene-age lakes. The North Coast HR corresponds to the boundary of RWQCB 1. Significant geographic features include basin areas such as the Klamath River Basin, the Eureka/Arcata area, Hoopa Valley, Anderson Valley, and the Santa Rosa Plaiu: Othei sighiticant features include MounfShasra, forming the southern harder of Shasta Valley, and the rugged north coastal shoreline. The 1995 population ofthe entire region was about 606,D00, with most being centered along the Pacific Coast and in the inland valleys north of the San Francisco Bay Area. The northern mountainous portion of the region is rural and sparsely populated, primarily because of the rugged terrain. Most of the azea is heavily forested. Some irrigated agriculture occurs in the narrow river valleys, but most occurs in the broader valleys on the Modoc Plateau where pasture, grain and alfalfa predominate. In the southern portion of the region, closer to urban centers, crops like wine grapes, nursery stock, orchards, and truck crops are common. A majority of the surface water in the North Coast HR goes to environmental uses because of the "wild and scenic" designation of most of the region's rivers. Average annual precipitation ranges from I00 inches in the Smith River drainage to 29 inches in the Santa Rosa area and about 10 inches in the Klamath drainage; as a result, drought is likely to affect the Klamath Basin more than other portions of the region. Communities that are not served by the area's surface water projects also tend to experience shortages. Surface water development in the region includes the U.S. Bureau of Reclamation (USSR) Klamath Project, Humboldt Bay Municipal Water District's Ruth Lake, and U.S. Army Corps of Engineer's Russian River Project. An important factor concerning water demand in the Klamath Project area is water allocation for endangered fish species in the upper and lower basin. Surface water deliveries for agriculture in 2001, a severe drought year, were only about 20 percent of normal. Groundwater Development Groundwater development in the North Coast HR occurs along the coast, near the mouths of some of the region"s major rivers, on the adjacent narrow marine terraces, or in the inland river valleys and basins. Reliability of these supplies varies significantly from area to area. There aze 63 groundwater basins/ subbasins delineated in the region, two of which aze shared with Oregon_ These basins underlie approximately 1..022 million acres (1,600 square miles). Along the coast, most groundwater is developed from shallow wells installed in the sand and gravel beds of several of the region's rivers. Under California law, the water produced in these areas is considered surface water underflow. Water from Ranney collectors installed in the Klamath River, Rowdy Creek, the Smith 122 DWR-BULLETIN it& River, and [he Mad River supply the towns of Klamath, Smith River and Crescent City in Del Norte County and most of the Humboldt Bay area in Humboldt County. Except on the Mad River, which has continuous supply via releases from Ruth Reservoir, these supplies are dependent on adequate precipitation and flows throughout the season. In drought years when streamflows are tow, seawater intrusion can occur causing brackish or saline water to enter these systems. This has been a problem in the town of Klamath, which in 1995 had to obtain community water from a private well source. Towazd the southern portion of the region, along the Mendocino coast, the Town of Mendocino typifies the problems related to groundwater development in the shallow marine terrace aquifers. Groundwater supply is limited by the aquifer storage capacity, and surveys done in the Town of Mendocino in the mid-1980s indicate that about 10 percent of wells go dry every yeaz and up to 40 percent go dry during drought years. Groundwater development in the inland coastal valleys north of the divide between the Russian and Eet Rivers is generally of limited extent. Most problems stemming from reliance on groundwater in these areas is a lack of alluvial aquifer storage capacity. Many groundwater wells rely on hydrologic connection to the . _ __ _c.t _ .._A-_-- 'PL.- r':...

South of the divide, in the Russian River drainage, a significant amount of groundwater development has occurred on the Santa Rosa Plain and surrounding areas. The groundwater supplies augment surface supplies from the Russian River Project. In the north-central part of the North Coast HR, the major groundwater basins include the Klamath River Valley, Shasta Valley, Scott River Valley, and Butte Valley. The Klamath River Valley is shazed with Oregon. Of these groundwater basins, Butte Valley has the most stable water supply conditions. The historical annual agricultural surface water supply has been about 20,000 acre-feet. As farming in the valley expanded from the early I950s to the early 1990s, bringing nearly all the arable land in the valley into production, groundwater was developed to farm the additional acres. It has been estimated that current, fully developed demands are only about 80 percent of the available groundwater supply. By contrast, water supply issues in the other three basins are contingent upon pending management decisions regazding restoration of fish populations in the Klamath River and the Upper Klamath Basin system. The Endangered Species Act (ESA) fishery issues include lake level requirements for two sucker fish species and in-stream flow requirements for coho salmon and steelhead trout. Since about 1905, the Klamath Project has provided surface water to the agricultural community, which in rum has provided water to the wildlife refuges. Since the early 1990s, it has been recognized that surface water in the Klamath Project is over-allocated, but very little groundwater development had occurred. In 2001, which was a severe drought year, USBR delivered a total of about 75,000 acre-feet of water to agriculture in California, about 20 percent of normal. In dte Klamath River Groundwater Basin this translated to a drought disaster, both for agriculture and the wildlife refuges. In addition, there were significant impacts for both coho salmon and sucker fisheries in the Klamath River watershed. As a result of the reduced surface water deliveries, significant groundwater development occun'ed, and groundwater extraction increased from an estimated 6,000 acre-feet in 1997 [o roughly 60,000 acre-feet in 2001. Because of the complexity of the basin's water issues, along-term Klamath Project Operation plan has not yet been finalized. Since 1995, USBR has issued an annual operation plan based on estimates of available supply. The Scott River Valley and Shasta Valley rely to a significant extent on surface water diversions. In most years, surface water supplies the majority of demand, and groundwater extraction supplements supply as needed depending on wet or dry conditions. Discussions are under way to develop strategies to conjunctively use surface water and groundwater to meet environmental, agricultural, and other demands. n z b D N V z a z c x Ch UFO4NIF'S GP,CUPl ,?F'A7ER UPOFif 2003 123 Chapter] Norrh Coasi Hyaro loyic Region Groundwater Quality Groundwater quality characteristics and specific local impairments vary with regional setting within the North Coast HR. In general, seawater intrusion and nitrates in shallow aquifers are problems in the coastal groundwater basins; high total dissolved solids (TDS) content and general alkalinity are problems in the lake sediments of the Modoc Plateau basins; and iron, boron, and manganese can be problems in the inland basins of Mendocino and Sonoma counties. Water Quality in Public Supply Wells From 1994 through 2000, 584 public supply water wells were sampled in 32 of the 63 basins and subbasins in the North Coast HR. Analyzed samples indicate that 553 wells, or 95%, met the state primary Maximum Contaminant Levels (MCL) for drinking water. Thirty-one wells, or 5%, sampled have constituents that exceed one or more MCL.

Pr128000`.f 24619 Ukiah UWMPIDratt Report-August 200T1pratfUWMP (oH102007)tloc Ukiah, California City Code This code was last updated by ordinance 1080 passed June 14, 2006. ARTICLE 11. WATER SHORTAGE EMERGENCY 3600: FINDINGS: The City Council hereby finds and determines that the ordinary demands and requirements for water customers of the City may not, from time to time, be satisfied without depleting the water supply to the extent that there would be insufficient water for human consumption, sanitation, and fire protection. This ordinance is intended to prohibit any additional demands on the existing water supply, to prohibit all nonessential uses as defined herein, and to allocate the available water supply during any water shortage emergency to the end that sufficient water will be and remain available for human consumption, sanitation, and fire protection. (Ord. 691, §1, adopted 1977) 3607: DEFINITIONS: For the purpose of this Article the following terms, phrases, words, and their derivations shall have the meaning given herein: The word "shall" is always mandatory and never directory. A. Customer: The person using water supplied by the City. B. Director: The Director of Public Works of the City or his designated representative. C. Department: The Water Utilities Division of the Department of Public Works. D. Hand-Watering: Water supplied to a customer through a hose connected to the customer's piping system while such hose is hand held and such water used for exterior purposes. E. Irrigate: To water land, whether by channels, by flooding, by sprinkling, or any other means whatsoever except hand-watering. F. Water: Only water supplied by the City unless expressly provided otherwise or required by the context. (Ord. 691, §1, adopted 1977) E-I 3602: DECLARATION OF WATER EMERGENCY: When it appears that the City may be unable to supply the normal demands and requirements of water customers, the City Council may, by resolution declare a water emergency. The resolution shall specify the degree of emergency existing and shall place into effect the appropriate provisions of this ordinance. (Ord. 691, §1, adopted 1977) 3603: REQUESTS FOR VOLUNTARY RESTRICTIONS OF WATER USE STAGE I: Whenever the City Council, by resolution, declares Stage I water emergency to exist, the Mayor shall issue a proclamation urging citizens to institute such water conservation measures on a voluntary basis as may be required to reduce water demand to coincide with available supply. (Ord. 691, §1, adopted 1977) 3604: PROHIBITION OF NONESSENTIAL WATER USE STAGE II: It is unlawful for any person to use water for any nonessential use as hereinafter defined, whenever the City Council determines by resolution that a Stage II water emergency exists. (Ord. 691, §1, adopted 1977) 3605: NONESSENTIAL USES DEFINED: The following uses of water are nonessential: A. Use of water from public hydrants for any purpose other than fire protection and/or prevention. B. Use of water through any meter when the consumer had been given two (2) days notice to repair one or more leaks and has failed to complete such repairs. C. Use of water by a golf course to irrigate any portion of its grounds except those areas designated as tees and greens; except where the Director shall have determined that any such use is nonessential and written notice of such determination shall have been provided. D. Use of water to irrigate grass, lawns, ground cover, shrubbery, vegetable gardens, trees, or other outdoor vegetation. E. Use of water for the construction of any structure, including such use in dust control. E-2 F. Use of water to wash any sidewalk, walkways, driveway, street, parking lot, tennis court, or other hard surfaced area by hosing or by otherwise direct use of water from faucets or other outlets. G. Use of water to wash any motor vehicle, trailer, airplane, or boat by hosing or otherwise using water directly from a faucet or other outlet. H. Use of water to fill or refill any swimming pool. I. Use of water to add to any swimming pool not equipped with and using a pool cover. (Ord. 691, §1, adopted 1977) 3606: FURTHER NONESSENTIAL USES DEFINED STAGE 111: In addition to the nonessential uses set forth in §3605, the following additional uses are determined to be nonessential when the Council has, by resolution declared a State III emergency. A. Use of water in excess of the daily usage allotment hereinafter set forth: Single family or duplex (100 cu. ft. per 50 gallons -per permanent month) resident Multi-residential units (180 cu. ft. per 45 gallons -per permanent month) resident B. All other uses not expressly set forth in §3605 shall be limited to fifty percent (50%) of the prior water use for a similar period as determined by the Department from its records. Where no such records exist, prior water use shall be deemed to be the average prior water use of similar existing services as shall be determined by the Department from its records. C. Use of water to irrigate, the provisions of §3605 above to the contrary, notwithstanding. D. Use of water for hand-watering. (Ord. 691, §1, adopted 1977) 3607: NUMBER OF PERMANENT RESIDENTS: Each customer in whose name water is supplied to a residence shall upon request of the Director advise him under penalty of perjury the number of permanent residents using water supplied to that residence. If such a residential customer shall fail to so advise the Director, such residence shall be permitted the water allocation herein provided for one permanent resident. (Ord. 691, §1, adopted 1977) E-3 3608: TAMPERING WITH WATER METERS PROHIBITED: It is unlawful for any person to remove, replace, alter, damage, or otherwise tamper with any water meter or components thereof, including but not limited to the meter face, dials, or other water usage indicators, and any flow-restricting device installed thereon. (Ord. 691, §1, adopted 1977) 3609: VARIANCES: The Director may: A. Grant temporary variances for uses of water otherwise prohibited; or B. Adjust temporarily any or all consumer's allotment if he finds and determines that due to unusual circumstances to fail to grant such a variance would cause an emergency condition affecting health, sanitation, or fire protection of the applicant or the public; further, he may grant such adjustment in the case of a mixed residential/nonresidential use if he finds that such adjustment is necessary to place an equivalent allotment burden on said applicant. The City Council shall ratify or revoke any such variance or adjustment at its next scheduled meeting. No such variance or adjustment shall be retroactive or otherwise justify any violations of this ordinance occurring prior to issuance of said temporary variance or adjustment. (Ord. 691, §1, adopted 1977) 3610: VIOLATION OF WATER USE RESTRICTIONS; PUNISHMENT: It is a misdemeanor for any person to use or apply water received from the City contrary to or in violation of any restriction or prohibition specified in the Article, except both the first and second violations of this ordinance within any one year period shall be infractions.

Provide recommendations and install plumbing retrofit devices where needed. Assumptions: 1. The implementation schedule is assumed to be as defined for agencies signing the MOU in the year 2005. 2. Number of surveys necessary to complete is 15% of the baseline number of housing units in 2005. 15% of single-family units and 15% of multi-family units will be surveyed within 10 years of the date implementation is to commence. Surveys will be conducted according to the following schedule: 1.5% by end of the first reporting period, 3.6% by end of second reporting period, 6.3% by end of third reporting period, 9.6% by end of fourth reporting period, and 15% by end of the fifth reporting period. MOU, page 16 and page 17 Section E. d. California legislation requires that plumbing fixtures manufactured, sold or installed after early 1992 be low-water-use fixtures. Therefore, the greatest water savings can be achieved in pre-1992 homes. 3. Single-family water usage = 465 gpd/unit (60% is outdoor use) Single-family water usage was calculated based on historical water use per connection, and the projected number of/," connections in 2005 (based on Rate Study report that 8~% of connections are '/.'). It was assumed that the '/." connections were primarily single and multi-family units. Based on the General Plan for the City, 64% of the '/." connections were assumed to be single-family and 36% multi-family. The single and multi-family water usages were based on the assumption that the multi-family units use 40% of the water that the single family units use. Outdoor use is based on engineering judgment 4. Multi-family water usage = 186 gpd/unit (40% is outdoor use) See assumptions for single-family water usage. 5. Water savings from indoor leak detection, not including toilet leaks = 0.5 gpd per residence A & N Technical Services report (2000, page 2-20) (12.4 gpd per household repair; 4 percent of households audited have leaks). 6. Water surveys decrease outdoor water use by 10% MOU estimate is 10% (page 18, Section F)_ 7. Each water survey costs $55.00 This cost estimate is based on the Southern Califomia Water Company (SCWC) pilot exemption request filed with the CUWCC and dated June 29, 1999. The estimate includes marketing, contract labor, SCWC labor, overhead and materials. It is assumed that the City's cost would be similar to SCWC's. It is assumed that this DMM is done in conjunction with DMM 2. 8. The life span of a water survey is four years. A & N Technical Services report (2000, page 2-20) gives life spans for various components of a water survey. Four years was selected as a reasonable average value based on that information. 9. Water savings from indoor plumbing retrofits are tracked under DMM 2. Only water savings from a decrease in outdoor water use and water savings from indoor leak detection are tracked in DMM 1 to avoid double counting of water savings. P.A 128000V 128(77 - CAiah C W MPA D;am iAnalysisVappcndis D: - .Assump6nns 200idoc DMM 2 -Residential Plumbing Retrofit Description: Install plumbing retrofit devices in single- and multi- family residences. Assumptions: 1. Plumbing retrofit devices will be installed at a minimum of 10% of residences per reporting period until it can be demonstrated that 75% of pre-1992 single-family residences and 75% of pre-1992 multi-family residences have low Flow showerheads (LFSHS). Based on the low growth rate, it is assumed that the current residences were all built prior to 1992. MOU, page 19. 2. 22.5% of residences have low-water-use fixtures. We estimate, based on professional judgement, that 45% of plumbing fixtures in pre-1992 residences have been replaced with low-water-use fixtures due to natural attrition. Assuming that one-half of these plumbing fixtures have replaced all fixtures in some pre-1992 residences and one-half of these plumbing fixtures are spread out, replacing only a portion of the fixtures in some pre-1992 residences, then 22.5 percent ofpre- 1992 residences already have low-water-use fixtures. 3. It will take approximately 15 years to demonstrate that 75% of residences have LFSHs. We are assuming that two LFSHs in a residence must be replaced to meet MOU requirements. If 22.5% of the residences have low-water-use fixtures, then 52.5% of the pre-1992 residences must still be replaced. At 5% of the residences replaced per year (10% replaced per repoRing period) it would take 15 years to demonstrate that a total of 75% of residences have LFSHS. 4. There are an average of 1.1 showers, 1.6 toilets, and 2.4 faucets (1 kitchen faucet and 1.4 other faucets) per residence. For DMM 14, we determined that there is an average of 1.6 toilets per residence (see DMM 14 for details). Based on professional judgement, we assumed there are two-thirds the number of showers as toilets, and 1.5 times the number of faucets as toilets. This assumption will be modified based upon updated data gathered in the future. 5. Water savings from one low-flow showerhead = 5.5 gpd A & N Technical Services report (2000, page 2-16). 6. Water savings from one faucet aerator = 1.5 gpd A & N Technical Services report (2000, page 2-16). 7. Water savings from one toilet flapper = 8 gpd; assume 20 percent of toilets leak. A & N Technical Services report (2000, page 2-16). Percentage of toilets with leaks based on SCWC data. 8. Water savings from kitchen "flip" faucet aerator = 3.0 gpd. Based on SCWC data. Kitchen faucet water savings are due to the intermittent use of the flip feature during the rinse cycle. 9. Indoor water savings = 13.7 gpd/unit. We used the following equation to calculate indoor water savings, based on assumptions 4 through 8: [(1.l*5.5)+(L0*3.0+1.4*LS)+(1.6*8*0.20)~ 10. The DMM will cost an average of $20.00 per residence We based this cost estimate on information provided by SCWC. It is assumed that this DMM is done in conjunction with DMM 1. 11. The life span of the retrofit devices is four years. A & N Technical Services report (2000, page 2-16) gives life spans for various components of a water survey We selected four years as a reasonable average value based on that information.

Assumptions 1. Each rebate will cost $75. The MOU does not require implementation of this DMM if the maximum cost-effective rebate is less than $50 (MOU, page 31). A $50 rebate plus an additional $25 per rebate for program administration and overhead was assumed. 2. Each high efficiency washing machine will reduce water usage by 1,170 gallons per year. MOU, Section F, page 38. 3. Rebates will be accepted by one percent ofsingle-family residences per year for 20 years. Estimate based on professional judgment. 4.

Assumptions: 1. There are an average of 2.5 people per single-family residence and 2.5 people per multi-family residence. Based on information in the General Plan for the City. 2. There are an average of 1.6 toilets per single-family residence and 1.5 toilets per multi-family residence. Based on professional judgment, it was assumed a one bedroom unit has 1 toilet, a two bedroom unit has 1.5 toilets, a three bedroom unit has 2 toilets, a four bedroom unit has 2.5 toilets and a five bedroom unit has 3 toilets. Because multi-family units tend to have fewer toilets on average than single-family units, it was assumed 1.5 toilets per multi-family residence and calculated that the single-family units would need to have 1.6 toilets per unit to achieve an overall average of 1.58 toilets per dwelling unit. 3. Water savings from ULFTs are 36.5 gpd/unit for single-family residences and 49.0 gpd/unit for multi- family residences. MOU, Exhibit 6, Table 1 and Table 2. 4. Homes constructed after 1991 already have ULFTs. Based on the low growth rate, it is assumed that no residences were built after 1991. As of January 1992, California legislation requires that ULFTs be installed in all newly constructed homes. 5. The life span of the new ULFTS is 20 years. MOU, page 70. 6. Natural toilet replacement rate is 4% per year. MOU, page 70. 7. Average resale rate for single-family units in Mendocino County is 2.56% Assumption based on the 1996 single-family average resale rate for Mendocino County. This rate was obtained from the CUWCC Website, www.cuwcc.org, December 2005. 8. Average resale rate for multi-family units in Mendocino County is 1.2% Assumption based on the 1998 multi-family average resale rate for Mendocino County. This rate was obtained from the CUWCC Website, www.cuwcc.org, December 2005. 9. The cost of toilets, advertising, administration, overhead, and toilet recycling is $150 per ULFT. The cost does not include installation, which will be covered by the customer.

It is agendized at this meeting to answer any questions the Council may have regarding the process. SUMMARY: Because the City operates a water system with more than 3000 service connections, it is required to adopt and update every five years an urban water management plan. The attached draft plan updates the UWMP last updated in 2002. The plan covers various topics, which are identified in Water Code Section 10631, which is part of Attachment 1. In general, a plan covers the next 20 years in five year increments and attempts to project over that time period the water system service area, its existing and planned sources of water, the reliability of its water supply, including in average, single dry and multiple dry water years, and the quantity of water projected to be needed to meet expected demand. If there are deficiencies in the quantity or reliability of the supply, the RECOMMENDED ACTION: Review and provide any preliminary comments or questions regarding the draft UWMP; further discussion and comment to occur at the September 5 City Council meeting. ALTERNATIVE COUNCIL POLICY OPTIONS: N/A Citizens Advised: N/A Requested by: Public Utilities Department Prepared by: David J. Rapport, City Attorney Coordinated with: Candace Horsley, City Manager, Tim Banyai, Brown and Caldwell, Robert C. Wagner, Wagner and Bonsignore, Gary Weatherford Attachments: Attachment 1-Draft Urban Water Management Plan update Attachment 2- Water Code sections Approved: Candace Horsley, City Manager Agenda Summary Report Page 2 August 15, 2007, City Couneil meeting plan is supposed to propose means of addressing those deficiencies, including conservation. The draft plan, Attachment 2, includes the current City boundaries and the sphere of influence proposed by the City/County tax sharing subcommittee as the service area projected over the next 20 years. Based on population projections supplied by Leonard Charles, it calculates the use of water within that service area. The plan identifies the City's water rights and sources available to serve that area and estimates the amount of water that will be needed to meet that demand. Section 3.10 of the plan includes a preliminary analysis of the impact of reduced Eel River diversions on the City's water supply and system capacity. The plan notes that the City has requested assistance from the Sonoma County Water Agency to develop more accurate computer models which evaluate the impact of the changes in Eel River diversions. The formal process for adopting the plan requires a public hearing with 14 days prior notice published twice in a newspaper of general circulation. Water Code Section 10642 encourages public participation in the preparation of the plan. Accordingly, the City staff is sending the plan to numerous public agencies, which are identified in the plan, for comment' and is asking for those comments by September 15, 2007. The plan may be revised, based on those comments, before it is presented to the City Council for formal adoption after conducting the required hearing. Staff's goal is to schedule the public hearing for the second meeting in October. The Urban Water Management Plan is an important document. It is submitted to LAFCO for its consideration in approving spheres of influence and proposed annexations. Under Government Code §65352.5, the County is supposed to consider it, whenever water planning is involved in a substantial amendment to its general plan, as is the case with the proposed Ukiah Valley Area Plan currently being considered by Mendocino County. The water agency is required to implement the plan in accordance with a schedule set forth in the plan. (Attachment 1, Water Code § 10643.) 'See Table 1-1, p. 1-3 in Attachment 2.

ATTACHMENT 3 ITEM NO: 10b MEETING DATE: Sept. 19, 2007 AGENDA SUMMARY REPORT SUBJECT: REVIEW AND DISCUSS DRAFT UPDATE OF URBAN WATER MANAGEMENT PLAN; SCHEDULE HEARING FOR ADOPTION OF PLAN SUMMARY: The draft update of the City's Urban Water Management Plan (UWMP) was distributed and briefly discussed at the August 15, 2007 City Council meeting. The item is on the agenda for this September 19 meeting for further comment and discussion by the City Council. The Agenda Summary Report for the August 15 meeting also attached the sections from the California Water Code requiring and governing the preparation of Urban Water Management Plans. LEGAL REQUIREMENTS FOR URBAN WATER MANAGEMENT PLANS Water Code §10642 contains the procedural requirements that the City must satisfy before adopting an update of the plan. It "encourages the active involvement of diverse social, cultural, and economic elements of the population within the service area prior to and during the preparation of the plan." It also requires the City to make the plan available for public inspection and to hold a public hearing before adopting or updating the plan. Prior to the hearing, notice of the time and place of hearing must be published once a week for two successive weeks with at least 5 days between the first and second publications. The City must also provide notice of the time and place of the RECOMMENDED ACTION: Review and provide any comments or questions regarding the draft Urban Water Management Plan and schedule hearing for adoption of plan. ALTERNATIVE COUNCIL POLICY OPTIONS: N/A Citizens Advised: N/A Requested by: Public Utilities Department Prepared by: David J.

Wagner, Wagner and Bonsignore, Gary Weatherford Attachments: Attachment 1-List of agencies and interested parties Attachment 2- Wagner memorandum re: water rights Approved: Candace Horsley, City Manager Agenda Summary Report Page 2 September 19, 2007, City Council meeting hearing to the County of Mendocino. After the hearing, the plan shall be adopted as prepared or as modified after the hearing. Consultants to the City have consulted with the Mendocino County Planning Department, the Mendocino County Water Agency and the Sonoma County Water Agency in preparing the plan. The City has sent copies of the draft plan to numerous public agencies and other interested parties and made copies available at the Civic Center, the public library and on the City's website. The list of agencies and other interested parties who were sent copies of the plan is attached as Attachment 1. An accompanying letter, included in Attachment 1, requested comments by September 15. Comments will be accepted at any time up to the time that the City conducts the required hearing. Staff will distribute comments and any staff discussion of them at or prior to the September 19 meeting. It is staffs' intent to carefully consider all comments and consult with the commenters prior to finalizing the plan for consideration at the noticed public hearing. Staff has a goal of conducting the required hearing at the regular City Council meeting of October 17, but the City Council may schedule the hearing at a different time if it determines that additional time is needed to fully evaluate and respond to all the comments received. The Water Code requires an urban water management plan to be updated at least once every five years on or before December 31, in years ending in five and zero. (Water Code §10621.) The City's plan was last updated on October 13, 2002. The plan must describe and evaluate sources of water supply, reasonable and practical efficient uses of water, reclamation and demand management activities. The components of the plan may vary according to an individual community or area's characteristics and its capabilities to efficiently use and conserve water. The plan shall address measures for residential, commercial, governmental, and industrial water demand management. In addition, a strategy and time schedule for implementation shall be included in the plan. (Water Code §10615.) Water Code Section 10630 states that the Legislature intends the level of water management planning to be commensurate with the numbers of customers served and the volume of water supplied. In other words, small systems do not have to engage in the same level of planning as larger systems. A system must have more than 3000 connections before a plan is required. (Water Code §10617.) The City's system is a small system among urban water suppliers required to adopt a plan. The elements of an urban water management plan are set forth in Water Code Sections 10631-10635.) The draft plan update is organized to comply with these requirements. In general, a plan update covers the next 20 years in five year increments and attempts to project over that time period the water system service area, its existing and planned sources of water, the reliability of its water supply, including in average, single dry and multiple dry water years, and the quantity of water projected to be needed to meet expected demand. If there are deficiencies in the quantity or reliability of the supply, the Agenda Summary Report Page 3 September 19, 2007, City Council meeting plan is supposed to propose means of addressing those deficiencies, including conservation. DESCRIPTION OF PLAN EVALUATION OF WATER DEMAND AND AVAILABILITY This summary is not intended as a substitute for reading the plan update itself, including the executive summary. The plan covers a number of subjects not addressed here, including limitations on the City's present treatment and pumping capacity, proposed demand management practices, the effects of low rainfall or drought conditions, groundwater basin information and opportunities for using recycled water. The draft plan update includes the current City boundaries and the sphere of influence proposed by the City/County tax sharing subcommittee as the service area projected over the next 20 years. (See Plan, Figure 2-2, p. 2-3.) Based on population projections supplied by Leonard Charles, it calculates the use of water within that service area. The plan identifies the City's water rights and sources available to serve that area and estimates the amount of water that will be needed to meet that demand. The plan anticipates that, at a 1 % annual growth rate, the City will reach build-out within its existing boundaries and a population of 17,992 by the year 2015. It estimates a water demand at that point of 4,730 acre feet per year (AFY). The plan assumes that the City will annex its entire proposed sphere of influence within 20 years. Over that time, it projects the population within that area to reach 12,675 and a water demand of 3,332 AFY. Combining these two areas, it projects a total future water demand over the next 20 years of 8,062 AFA. (Plan, pp. ES-4 to ES-5.) It observes that this total demand is less than the City's right to divert up to 20 cubic feet per second (cfs) under its water rights permit. The plan converts the 20 cfs rate of diversion to approximately 8400 AFY. (Plan, p. ES-3.)' The plan states that the City's water sources currently include the Ranney Collector and Well Nos. 3 and 52 which draw from Russian River underflow pursuant to the City's appropriative water rights permit, and Well No. 4 which is classified as percolating groundwater. The City does not require a permit to use percolating groundwater. (See, e.g., ES-1 to ES-2.) It states that the City is currently undertaking a well siting study and that increased water demand will be satisfied by additional groundwater wells. (See Plan, ¶3.6, p. 3-6. See, also §3.10, p. 3-26.) Elsewhere in the Plan the 20 cfs entitlement is converted to 14,480 AFA, but this number is described as the "theoretical maximum." The Plan refers to the explanation in §3.10, p. 3-18, which states that the City will only use 8400 AFA, when it first puts the full 20 cfs to beneficial use. (Plan, Water Rights, p. ES- 3.) The theoretical maximum is derived by assuming a diversion of the full 20 cfs 24 hours/day, 365 day per year. In fact, the City will divert 20 cfs during its peak period of demand, which, in the past, has generally occurred in July. The 8400 AFA figure was derived by assuming the City would divert proportionally less water at other times of the year based on the City's historical pumping records. (Id.) The Plan recognizes that Well No. 5 is not currently included as a point of diversion under the permit and notes that the City has applied to add Well No. 5 as a POD under its permit. Agenda Summary Report Page 4 September 19, 2007, City Council meeting In Section 3.10, the plan update includes a preliminary analysis of the impact of reduced Eel River diversions on the City's water supply. The analysis was performed by Mr. Robert Wagner, a hydrologist and water rights specialist with the engineering firm of Wagner & Bonsignore. That analysis evaluates (1) whether, under the reduced diversions from the Eel River, sufficient water will be available in the Russian River below Lake Mendocino to meet the historic demand for water in the Russian River system, including the City's demand and (2) what effect it would have on water storage in Lake Mendocino, if the City diverted its full 20 cfs entitlement under its water rights permit. For the reasons previously stated, the analysis assumed that a diversion at 20 cfs under the City's permit would equate to approximately 8400 AFA. The analysis studied the 2004 amendments to PG&E's Federal Power Act license for the Potter Valley Project, which controls the diversions from the Eel River into the East Fork of the Russian River. It studied Water Resources Control Board decision D-1610 which establishes minimum flows in the Russian River below the Coyote Dam at Lake Mendocino. It used the actual diversions from Eel River and the flows measured at key gauging stations in the Russian River between 1961 and 2006. This data is presented in Tables 1-5 and Figures 1-10, attached to the report. Also attached are copies of the most important of the source documents relied upon in the analysis. Based on this review, the analysis predicts a 26% reduction in Eel River imports for power generation as compared to pre-2004 diversions. Without considering water rights, the analysis concludes that there is sufficient water in the Russian River system to meet the historic demands for water in the Russian River system and the future City diversions up to 8400 AFA in spite of these reduced Eel River imports to the East Fork Russian River. The analysis considered two scenarios for dry season (May through November) releases from Lake Mendocino, which it labeled Scenario A and Scenario B. Scenario A replicated historic releases from Lake Mendocino (up to 275 cfs). Scenario B reduced Lake releases so that, after river losses and diversions, the SWRCB Decision D-1610 minimum flow requirements were just met. Scenario B was predicated on the assumption that, historically, more water than necessary was released from the Lake. In both scenarios, there was sufficient water in the system to meet downstream demands on the Russian River, despite the reduced imports from the Eel River. However, water levels in Lake Mendocino were modeled as significantly lower due to the reduced imports (see Figure 6). Under Scenario B, late summer water levels would be approximately 6 feet lower than historical levels, on average. Scenario A late summer water levels were modeled as approximately 11 feet lower than historical levels, on average. Scenario B would require changes in how releases from Lake Mendocino are regulated by Sonoma County Water Agency (SWA), which has administrative control of releases from the lake. According to Mr. Chris Murray, a hydrologist with SWA with whom Mr. Wagner consulted, greater efficiency in operation of lake releases is achievable. Agenda Summary Repots Page 5 September 19, 2007, City Council meeting In each scenario, as reflected in Figures 8 and 10, a doubling of City diversions to approximately 8400 AFA could result in a lower average lake level in Lake Mendocino of approximately 1 foot under Scenario A and a negligible amount under Scenario B. The analysis assumed that any increased water extractions from the groundwater basin by the City would result in lower lake levels. The analysis points out, however, that the impact of the groundwater extractions may not result in an immediate reduction in stream flow. The stream flow reduction due to increased pumping in the dry season may well not be manifested until the following winter. In that event, sufficient water would be available from winter precipitation to replace the extractions. As a result, even the small predicted lake level reduction would not occur under those conditions. After the draft plan was circulated, the City Attorney asked Mr. Wagner to address the issue his analysis does not consider; namely, whether or not the City will infringe on Lake Mendocino storage rights that may be senior to the City, if the City exercises its full 20 cfs diversion right as authorized by its water right permit. Both the SWA and the Mendocino County Russian River Flood Control and Water Conservation Improvement District ("Flood Control District") have permits to the water stored in Lake Mendocino in the winter and released in the summer. Since the amount of water being imported into Lake Mendocino, especially in the spring and summer, is being substantially reduced, the City Attorney wanted Mr. Wagner to analyze whether increased diversions under the City's permit to its full 20 cfs entitlement would infringe on the water rights of the Flood Control District, the SWA, or other water rights which are senior to the City's. Attached as Attachment 2 is his response. In summary, he concludes that current city diversions from Russian River underflow of approximately 6.833 cfs in the summer can be met from: 1. pre-1949 water rights (2.8 cfs), which are senior to the rights to project water held by SWA and the Flood Control District, and 2. the City's contract with Flood Control District for project water (4.033 cfs). The City has a water supply contract with the Flood Control District (FCD) for 800 AFY of project water. Mr. Wagner estimates that if the City used the 800 AFY for 100 days in the summer, it would equate to a diversion of 4.033 cfs during that time. This contract right in combination with the City's pre-1949 right totals 6.833 cfs. In addition, Well No. 4 produces approximately 1.75 cfs year round, giving the City as much as 8.583 cfs to meet current demand without infringing senior water rights held by SWA or the FCD.3 As to future diversions to put the remaining water under the City's permit to beneficial use, Mr. Wagner concludes that the future diversion of up to 11.4 cfs will come from groundwater extracted from the Ukiah Valley groundwater basin, and that increased future extractions from the groundwater basin are not an infringement on East Fork water released from storage in Lake Mendocino. ' Mr. Wagner notes that additional non-project water may be available in the summer to pump under the City's permit,. including water from the West Fork, East Fork, infiltration of direct precipitation, groundwater accretion and return flow. His response does not rely on these additional sources. Agenda Summary Report September 19, 2007, City Council meeting Page 6 For these reasons, he concludes that the City can meet its present and future water demand without infringing on SWA or Flood Control District rights to project water, not already included in the City's current contract. He indicates that he is completing an analysis of other water rights that are senior to the City's 1954 priority date, and should have the analysis complete before the City Council is asked to adopt the final urban water management plan. At the September 19 meeting, staff will attempt to answer questions from the City Council and members of the public and will take comments back to the consultants for additional analysis, if needed or requested.

Wagner, P.E. Date: September 14, 2007 Re: Potential Infringement of Water Right Priorities on Releases from Storage in Lake Mendocino by the Full Exercise of the City's Water Right Permit. You asked us to address the question of whether or not the City will infringe on Lake Mendocino storage rights that may be senior to the City, if the City exercises its full 20 cfs diversion right as authorized by its water right permit. The analysis that we prepared for the Draft Urban Water Management Plan concluded that there was sufficient water in the Russian River system to meet the historic demands and the future City diversions in spite of the reduced Eel River imports to the East Fork Russian River, a source of water for Lake Mendocino. We evaluated two scenarios for dry season demands downstream on the Russian River: A) lake releases are equal to historical releases (up to 275 cfs) and B) lake releases can be decreased from historical rates so that, after river losses and diversions, the Decision 1610 required flow rates are just met. In both scenarios, there was sufficient water; however lake levels were predicted to be significantly lower in Scenario A than in Scenario B. "fhe difference between Scenario A and Scenario B is the underlying assumption that releases to satisfy D-1610, in the past have been inefficient. In essence Scenario B is a management change resulting in a more efficient lake operation. According to Mr. Chris Murray of the Sonoma County Water Agency such efficiency in operation is achievable. In each scenario our analysis concluded that the City's diversions in the past have no impact at all on lake levels in Lake Mendocino and do not result in a reduction of water in storage. Any predicted lake level changes based on past releases and reduced imports are a function of changed regulatory constraints. The City's water right permit is for 20 cfs to be diverted from Russian River underflow. The City's points of diversion are located downstream of Lake Mendocino and the water that is diverted or extracted includes water from the West Fork, East Fork, infiltration of direct precipitation, groundwater accretion and return flow. The City does not divert from the lake, nor is it reliant on the water supplied from the East Fork to satisfy diversions under its water right permit. 444Abrtl~ 77Nrrt.Shae4 Suae325, Swcamrre~Wl Cat~Ornla 958740228 Ptr: 976441.6850 N.r 916448-3866 Mr. David Rapport September 14, 2007 Page 2 A portion of the City's water right is derived from apre-1949 right for 2.8 cfs which can be satisfied from the East Fork of the Russian River. Water released from storage in Lake Mendocino and the source of the water to satisfy the water rights for the lake is restricted to the East Fork. The relative priority to the water of the East Fork between the City and the Flood Control District is first to the City for at least 2.8 cfs and second to the District for amounts in excess of the City's pre-1949 water right. The City also has a contract with the Flood Control District for 800 acre feet (assuming the contract was exercised every year for 100 days, the contract amount would equate to a rate of 4.033 cfs or about the same amount that the Ranney collector diverts). Therefore, the City's diversion of 6.833 cfs from the East Fork would constitute no infringement on the senior rights of the Flood Control District. The City's well number 4 pumps about I J5 cfs of groundwater from the Ukiah Valley groundwater basin. Consequently, the City has access to, at least, 8.583 cfs of water based on water rights that are either senior or equal in priority to the District or available from percolating groundwater. The remainder of the water to be diverted by the City in the future, about 11.4 cfs, will come from groundwater extracted from the Ukiah Valley groundwater basin (whether or not the groundwater is subject to SWRCB jurisdiction). With respect to priority between the City and the Flood Control District, the District's water right permit does not authorize it to divert from the Ukiah Valley groundwater basin, or from the West Fork, or any source other than the East Fork Russian River. We made an estimate of the flow at the forks and at Hopland absent storage regulation by Lake Mendocino and as reduced by the 2004 amended FERC license for Potter Valley Project. The area between forks and Hopland is roughly the area containing the Ukiah Valley groundwater basin. The average June and July flow at the forks flow would be about 95 cfs. The average July flow at Hopland would be 63 cfs. ]n some years the flow would be substantially greater and some years less. For example, at Hopland, 5 of the 46 years modeled, the surface flow would have been zero in July. June flows would average 85 cfs with zero flow in 5 out of 46 modeled and August flows would average 88 cfs with zero flow in 2 out of 46 years. September flows would average 156 cfs and May flows would average 202 cfs. It is important to restate that the City's future diversions will come from groundwater extractions and will not be dependent on the surface flow at the forks, since the City will be able to rely on water stored in the groundwater basin. The cursory evaluation of unregulated flow at the forks and at Hopland is an indicator that the groundwater basin recharges every year without the regulated storage releases from Lake Mendocino Additional evaluation of groundwater levels in the Ukiah Valley will need to be made to identify patterns of seasonal changes in groundwater storage. The City's future extractions from the groundwater basin, are not an infringement on the East Fork water rights. The City's permit was issued with a diversion season of January I to December 31 and is unconstrained by the D-1610 minimum flow conditions. The D-1610 flow conditions adopted in W~a~ner~Bonsignore Mr. David Rapport September 14, 2007 Page 3 1986, included an accounting of the existing water rights on the Russian River as of that time. The City's permit, with a priority date of 1954, was issued with the finding that there was 20 efs of water (Russian River Underflow) available to satisfy the demand. Additional questions regarding the relative priority of the City to Russian River Underflow will be addressed as we continue to evaluate the water right priorities that are senior to the City's water right and have a common source. We have compiled most of the data and we expect to finalize that work in the next three to four weeks. We are also updating the water level data we previously compiled to evaluate the seasonal and long term trends in changes in groundwater storage. Please contact me if you have any questions.

AGENDA SUMMARY REPORT ~urs~tcT: REVIEW AND DISCUSS DRAFT UPDATE OF URBAN WATER MANAGEMENT PLAN SUMMARY: The City Council continued this item to its meeting on October 3, 2007. Robert Wagner will present his analysis contained in Section 3.10 of the draft Urban Water Management Plan and his opinion as expressed in the memorandum attached to the Agenda Summary Report on this item that was prepared for the September 19 City Council meeting (Attachment 2). He will be available to answer questions from the Council and members of the public. Since the Council's previous consideration of this item, the City has received amark-up from Sonoma County Water Agency (SCWA). The mark-up is attached as Attachment 1. Most of the comments require clarification of the items addressed. Staff will be either providing clarifying language or recommending no change to Council. Four comments address Mr. Wagner's analysis. He will review those comments with the City Council and respond to them at the meeting. As stated at the last City Council meeting, the staff and consultants are reviewing the plan to make certain that terms such as "groundwater," "percolating groundwater," and "underflow" are defined properly and used consistently throughout the plan. As of this writing, staff has not received any other comments on the plan. To comply with the two week public notice requirements, staff has published notice of a public hearing on adopting the plan for the October 17, 2007, City Council meeting. If the City Council decides that it needs more time to act on the plan, the hearing can be continued on October 17 or a new notice can be published later.

The UWIvfP is prepared in compliance with the Urban \4'ater Management Planning Att {California \Y~ater Code Division G, Part 2.G, Sections 1OG10 through 1OG57). This act requires that all urban water suppliers providing water for municipal purposes to more than 3000 customers or supplying more than 3000 acre-fee[ annual!}' prepare an [JWIv1P update every flee years. The goal of the U1YRviP is to assure that every effort is made to provide the appropriate level of reliability in water service to meet the needs of the various customers during normal, dry, and multiple dry years. The LJ\K"MP documents the City's planning activities for the next 25-}'cars to ensure that this goal is met. The UWMP is submitted to the California Department of Water Resources (D\\72) for general compliance with the Urban IX~a[er Management Planning Act. The following sections provide a summary of this U\VIvfP. Water System Chapters 2 and 3 of the U\\QvCP present a description of the Ciry's existing water supply and veamaent facilities, water rights, and distribution system. \X'ater supply is defined as the amount of water available Crom a source or combination of sources (e.g., streams, rivers, ponds, lakes, groundwater, etc.) for use by a water purve}'or. Water supplies from die Russian River and its underfloor are subject to the State Water Resources Convol Board (SWRCB or Slate Water Board) requirements outlined in the Cit}%s water right permit. A water right permit or hcensc provides the legal entitlement to divert water from a defined channel by a user Crom a specified source (.eater supply) For a beneficial, non-wasteful, use. The permit or license spells out the point of diversion, place of use, purpose of use, the amount or rate of warer drat can be diverted, and the time allowed for putting water diverted under the permit to beneficial use. Sources, such as percolating groundwater, that are not from the Russian River or its underfloor, do not require a permit or license issued by the Slate Water Board. Just as a water right permit or license resvicts the amount of water available for use, pumping and veatment -' capacity can also limiit the amount of warer that can be diverted from a water supply. Pumping capacity is the amount of water the City can physically divert using its diversion works (wells, pumps, storage tanks, etc.) under its water right permit or from non-permitted sources such as percolating groundwater or water subject to pre-1914 water rights. The pumping capacity is dependent on the pump (low rating and aquifer yield. The water veatmem and its capaciry are regulated by the strict requuemehts of the California Department of hlealth Services (DHS). Water Supply. The Ciry obi ~ s it~vat r supply from the underfloor of the Russian River (surface water) and one groundwater well. The pu to ources for the disviburion system consist oC a Ranney collector and two wells (\Y~ells 3 and 5), which are considered underfloor of the Russian River and subject to the requirements of the water right permit, and one groundwater well (\tUell 4). Well 4 is believed to be from percolating groundwater and not underfloor of the Russian River; and therefore, is considered a groundwater source. \Y'ells 1, 2, and G are no longer used by the fit}' Well 1 has been out of service since the 1970's. Wells 2 and G (\\'ater from \X~ell G is pumped into Well 2) were removed Crom the Ciry's latest domesoc water supply ~._..~ ~. Fri s s' t s°,,~.r ,,,8 ~....

The Flood Convol Disvic[ can only terminate the convict with five years prior notice to the Ciry. Water Dlstrlbution System. The water distribution system consists of surface water well pumping, percolating groundwater well pumping, water vestment plant high sea=ice pumping station, storage reservoirs, and piping to and within the water distribution system. After chlorination, surface water \\tells 3 and 5 are pumped direcdy into the disrnbuuon system. Well A, following chlorination, also pumps directly into the water distribution system. The Ivgh service pumps are located at the water veatmcat plant and take stored vented water and pump it into the water disvbution system. The Cit}• has tight reservoirs. The combined storage capacity of the reservoirs is G.1 million gallons (18.7 AF). -the storage provides short [erm vested witcr storage [o be used on a daily basis and for emergency situations such as fve fighting. ]t is no[ recognized as a water suppl}' source. Water Use. Based on the average w•atcr use from 2000 through 2004, the City uses approxima[ely 4,070 AF. of water annually. Reliability. To evaluate the reliability of the system, afour-year draught that would yield 50 percent less water supply, based on the City's water right, was anal}'zed as the worst case scenazio. This anal}'sis was evaluated on an annual basis.

Historically, the Ciry has experienced slow population growth and this vend is expened to continue. An annual population growth rate of 1 percent was assumed (or the Cit}•. Based on a 1 percent population growth rate, the Ciry will reach abuild-out population of 17,992 in 2015. Tlus eouesponds to a water use of 4,592 AF annually. Based on estimates provided b}' the City, a rough estimate of unaccounted For water (e.g., water in the system that is tin-metered water use such as fve ES~4 pR4ri log review BupoSe=_ only F ~17NOW1; <R51y.

Therefore, the mtal protected water demand within the present City limits is 4,730 AF. The Ciry has plans to annex land within its sphere of influence widtin the next 20 years. The population within the sphere of influence is expected to increase from approximately 5,675 to 12,675. This is an increase of 7,000. At 2.86 people per connection, which is the average number of people per connection for [he City, the total number of connections for a population of 12,675 is 4,432. The City's average water use per connection is 0.73 AFY. Using dais same average water use For the connections within the sphere of infuence, the water use is 3,235 AhY. Including the 3 percen unaccounted for water loss, dais value increases to 3,332 AFY. ]t should be noted that some of the connections witiin the City's sphere of in (]uence arc served by other water districts. This U\Xn4P assumes that in the next 20 years, these connections will eventually be served by the City's water system. 1'he total water use for the City, including the City's sphere of influencq is 8,062 acre-feet per year (AFB. The City's demand falls below its total water rights of 8,400 AFY tlvough 2030. However, at times, the City has a difficult time meeting demands, especially peak demands during extended periods of hot weather or drouglu conditions. The reason die City's water system cannot meet the peak water demands during these periods is because the pumping capacity of the existing Ranney collector, surfacewater wells, and groundwater well is ]ir»ired. The City has increased storage capacity in the water distribution system that helps with short term emergency capacity. I-lowevet, DHS does not classif}' the City's water storage capauty as a water supply. To increase the pumping capacity to provide a more rehable and redundant water supply, the City is conducting a groundwater well siting study to increase groundwater well production by 1,500 gym. These improvements will help the City meet its peak demands. The City's water right includes Pre-1')49 and Post-1949 water rights. The Pre-7949 Appropriative water right of 2,027 AF annually is senior to Project \X/ater (water stored in Lake Mendocino, see §2.3.3.3). This water right is recognized by the State \water Board.'- The Post-1949 Appropriative Water Right has a 1954 priority date and is senior to subsequent appropriators. Water Supply Versus Demand Comparison Chapter G provides a comparison of projected water supplies versus demand. It also discusses water shortngc expectations. The water use, including the City's sphere of influence, will be approxvnately S,OG2 AFY compared to 8,550 AFY of water supply expected during amulti-year drought. The 5,550 AFY of water supply is based on a 50 percent reducdonin water supply based on [he City's water right. This analysis shows that during severe drought conditions, the City has sufficient wat~~ p~l~baged on its water right. Although not likely, iC the State Water Board denies the City's T uapglt~[ta3' ~ ~7n!/toNextcnd the time [o put water authorized by its permit to beneficial use, the Ciry would have to fmd other methods to meet water demands. These methods could include use of recycled water, greater water conservation, and use of groundwater wells. Demand Management Practices Chapter 7 discusses water conservation and demand management practices. This chapter presents a description of the City's water conservation program. Included m the discussion is an economic analysis oC water conservation Demand Management Measures (DMMs) for DMM 1, 2, G, and 14. ~ As previously noted, the City also has pre-7774 water rights that pre-dated the Writer Commission Act.

INTRODUCTION Phis chapter provides an overview of the Urban Water Aanagement Plan (U\t(rhiP), discussion of pre~~ous reports, the Cit}~'s policy on public participation, and coordination efforts with other agencies. Table 7-1 summarizes the toordinauonwith other agencies. 1.1 Purpose The purpose of this UWMP is ro ensure efficient use and promote conservation of urban water supplies within the City of Ukiah (City), California. The U\~m7P describes the availability of water and discusses water use, reclamation, and water conservation activities. 1.2 Urban Water Management Planning Act Brown and Caldwell prepared this plan for submission to the California Department of \8rater Resources (D\\~R) on behalf of the City as requu~ed b}' the Urban Water Management Planning Act (Act) (California Water Code Division G, Part 2. G, Sections 10610 through 10657). \Yrater Code Section ]0620 requires any water supplier chat provides water to 3,000 or more customers, or that provides over 3,000 acre-fee[ of water annually, to prepare an Urban Water Management Plan that comphes with Water Code Sections 10630 and following. Urban water suppliers are required to develop water management plans to activcl}' pursue the efficient use of available water supplies to meet the needs of its various categories of customers during normal, dry, and muldple dry years. The Act describes the contents of the UWMP as well as how urban water suppliers should adopt and unplement the UV:RvIP. It is the intenfion oC the Legislatum, in enac[ing this par[, to permit levels of water management planning commensura[e with the numbers of customers served and dte volume of water supphed. For ease of review, the D\\~R Review Sheets arc located in Appendix A. 1.3 Previous Reports Two reports and the Ciry and Mendocino County (County) general plans were used in preparing this U\X/MP. Also, Barde \\!ells and \Y/agner and Bosignore were contacted. Barde Wells is a consulting Earn that specializes in financing and \Vagner and Bosignore specialize in water right issues. Included in this U\XT4P is a preliminary analysis completed by Wagner and Bosignore on the reduction of flow in the Eel Rivet This analysis is located at the end of Chapter~3. The reports and information obtained from the consulting fums address the water supply and demand for dte City. An understanding of the results of these previous documents provides a broader context for preparing an updated water management plan. The following paragraphs provide a summary of the documents.

This fmancing plan recommends updates to the water utility rate swcture and connection fee. Urban Water Management~Plan 2002. The 2002 UWMP was prepared by Kennedy Jenks, an engineering ronsulting firm hued by the City to Fulfill 2000 CJ\C~Iv(P requirements. The main purpose of this plan is to analyze the Citp's water supply and demand for [he following 25 }'ears during normal and drought years. The Plan also summarizes the City's water shortage contingency plan and water conservation program. 1-1 ORD.rt Im,enew pmaasss only P <II2003J 78fit9 Ukiyn Va'MlV6rdll Repcnl- hnCuL 70.t71D,cM1 VWMP IOC10709;1 Oa CITY OF UKfAH-.URBAN WATER MANAGEMENT PLAN 2.

The area is centrally located between San Francisco, Eureka, and Sacramento. The City is surrounded by coastal ranges in southern Mendocino County and situated in the fertile Yoka}'o Valley with rich vineyards and pear orchards. The valley is bordered on the west by the Mendocino Range and on the east by the Mayacamas Moumains. Elevations m the mountains are over 1,800 feet mean sea level (MSL), w(rile elevations in the valley range from about 670 feet MSL in the norh near Calpella to about SGO feet MSL in the south near EI Robles Ranch.

The City has developed a hypothetical four-year worst-case scenario to prepare for any conditions that may cause water supply shortages. From this scenario, afour-yeaz drought has been analyzed. It was assumed that the severity of this hypothetical period would yield 50 percent less water supply to die City. The estimated water supply and resulting water supply deficiencies caused by this extreme case are shown in Table 3-10. It can be seen from [his example that deficiencies in overall water supphes would not create a shor[age for City customers based on approximately 4,200 AP normal demand as [night be expected to occur in 2005 - 200G. However, die City's pumping capacity from its Ranne}' collector, surface water wells, and percolated groundwater well may be affected. During peak flow oc drought periods, when the water table is lower, the pumping capacity may be limited even more [han normal water years! The City has water rights to meet its demand, however, only the Pre-1949 2,027:\FY azeconsidered senior rights.. The City also has, on a contraceual basis, S00 AFY from the Flood Concro] District. The remairwtg water right is Post 1949 and is not senior to project water for the Last Pork of the Russian River andRussian River underflow. Demands are discussed in greater derail in Chapter i.

The Citv holds, amone other water riehts. a 1954 ~r ~ `~ appropriative water right permit for 20 cfs from Russian River Underfloor. This amount corresponds to approximately double the current water use. Physical water availability is expected to be affected by significant reductions in Eel River imports to the Russian River basin. Analyses were conducted to assess impacts to Lake Mendocino operations in response to reduced Eel River impons and to determine the effect on future water supply downstream of Lake Mendocino. The results show sufficient water supply available for the City and that increased diversions by the City will have only minor effects on Lake Mendocino operations. The City does not control Lake Mendocino and can not cause changes [o [Ile release requirements or the amount of Eel River imports. Those decisions are controlled by other agencies. The fallowing analysis shows that under a given set of assumptions there is sufficient water to mimic past releases during the summer months with the result that the reduced imports from the Eel River that are expected will not substantially affect the flow in the River. Lake Mendocino may experience significant changes in seasonal water surface due to reductions in imports, but since the City does not take water out of the lake directly it does not directly affect water levels or storage. It is important to note that the source of the City's water right is Russian River Underfloor which has several components including, Russian River (West Fork), ungaged tributary inflow, groundwater accretion, return flow, percolation of direct precipitation and natural flow from the East Fork Russian River and Eel River imports. In addition, the City pumps percolating groundwater from at least one of its wells. The following analyses treat all water supplies and all water diversions as having an equal effect on the system. This particular assumption as explained in more detail below is a simplifying and conservative assumption; the actual impacts are very likely to be less than the modeled impacts attributable to the City. Completed by Wagner and Bonsignore ~ 3-17 River basin and even with such a tool, considerable discretion for diversions remains to PG&E. t Based on the assumption that PG&E would be able and willing to maximize flow through the Potter Valley Project tunnel for power generation, it was decided that using historical imports for the July 18 through March 4 period would be a reasonable assumption in this.analysis f lpr,tl6.

A USACE database provided a daily record of outflow from the lake for water years 1961 through 2006. A monthly summary of Lake Mendocino historical outflow is provided in Table 5. Note that releases from the lake were much higher in the wet season of December through April. These high flows were not intended to meet downstream demand but rather resulted from flood control operations in Lake Mendocino. Downstream demands on the Russiatt River to Dry Creek during the wet season of December through Apri] were estimated based on application of the D-1610 minimum streamflow requirements to the period of record, 1961 through 2006. Downstream demands on the Russian River to Dry Creek for instream flow, recreation, agricultural use and municipal use during [he dry season of May through November were estimated in two different ways, leading to two Scenarios. In both scenarios, historical Lake ~ In a June 8, 2007, letter (attached) from Randy Poole (General Manager, SCWA) to David Moller (Manager of Relicensing, PG&E), Mr. Poole states, "The Agency and the County still do not know how PG&E is operating the Project, or whether operating the project using other criterion that is also consistent with the existing Federal Energy Regulatory Commission (FERC) license could have resulted in higher Lake Mendocino storage." Mr. Moller responded to Mr. Poole in a June 22, 2007 letter (attached) and acknowledged [hat "the reduction in diversions from the Eel River into the EBRR [East Branch Russian River] required by the license amendment was considerably greater than what had been anticipated during the amendment proceeding" but did not provide an ezplana[ion of how PG&E is operating the Potter Valley Project. Completed by Wagner and Bonsignore 3_22 releases during the dry season were used as a guide. Table 5 shows historical lake releases in the period May through November were typically in the range of 12,000 to 18,000 acre-feet per month. That corresponds to a rate of 200 to 250 cfs. Figure 4 shows the distribution of historical daily releases from Lake Mendocino during the months of May through November. This figure shows the percent of days during May through November that the Lake release exceeded the given value. The median flow was 230 cfs. Only 27 percent of the daily releases were greater than 275 cfs. The higher release rates suggest that there were surplus releases and thus were not considered to represent demands on the Russian River. Scenario A estimated downstream demands on [he Russian River for release from Lake Mendocino as the historical daily release capped at 275 cfs. In other words, historical daily releases less titan 275 cfs during the dry season of May through November were assumed to be the measure of downstream demand for fisheries, recreation, akricultural and municipal uses. On days when the May though November release exceeded 275 cfs, the downstream demand was assumed to be 275 cfs. D-1610 specifies a minimum instream flow from fire East Fork Russian River to Dry Creek far all months of rite year. If any of the historical Lake releases during May through November were insufficient to meet the D-1610 minimum requirement, the downstream demand in Scenario A was adjusted to satisfy the D-1610 requiremett. The D-1610 minimum streamtlow requirement was instrumental in estimating downstream demands in Scenario B. Review of historical gage records on the Russian River between Lake Mendocino and Dry Creek show river flow in excess of the D-] 610 requirement. Scenario B downstream demand for release from Lake Mendocino was estimated as the historical Lake release minus the amount that the minimum gaged flow in the river exceeded the D-1610 requirement. Both estimates (Scenarios) of downstream demand on the Russian River were based on historical Lake releases rather than a cataloguing of water tights or water diversions on the Russian River. In Scenario A, [he assumption was that historical Lake releases (up to 275 cfs) Completed by Wagner and Bonsignore 3-23 7/23/2007 TABLE 3 Projected Hydrological Classification for Inflows to Lake Pillsbury Potter Valley Project (FERC 77-110) JAN FEB MAR APR MAY JUN-DEC 1961 Normal Normal Normal Normal Normal Normal 1962 Normal Normal Normal Normal Normal Normal 1963 Normal Normal Normal Normal Normal Normal 1964 Normal Normal Normal Normal Normal Normal 1965 Normal Normal Normal Normal Normal Normal 1966 Normal Normal Normal Normal Normal Normal 1967 Normal Normal Normal Normal Normal Normal 1968 Normal Normal Normal Normal Normal Normal 1969 Normal Normal Normal Normal Normal Normal 1970 Normal Normal Normal Normal Normal Normal 1971 Normal Normal Normal Normal Normal Normal 1972 Normal Normal Normal Normal Normal Normal 1973 Normal Normal Normal Normal Normal Normal 1974 Normal Normal Normal Normal Normal Normal 1975 Normal Normal Normal Normal ~ Normal Normal 1976 Dry Critical Dry Dry Dry Dry 1977 Dry Critical Critical Critical Critical Critical 1978 Normal Normal Normal Normal Normal Normal 1979 Normal Dry Normal Normal Normal Normal 198D Normal Normal Normal Normal Normal Normal 1981 Normal Normal Normal Normal Normal Normal 1982 Normal Normal Normal Normal Normal Normal 1983 Normal Normal Normal Normal Normal Normal 1984 Normal Normal Normal Normal Normal Normal 1985 Normal Normal Normal Normal Normal Normal 1986 Normal Normal Normal Normal Normal Normal 1987 Dry Dry Normal Normal Normal Normal 1988 Normal Normal Normal Normal Normal Normal 1989 Normal Normal Normal Normal Normal Normal 1990 Normal Normal Normal Normal Dry Dry 1991 Dry Critical Critical Dry Dry Dry 1992 Critical Dry Normal Normal Normal Normal 1993 Normal Normal Normal Normal Normal Normal 1994 Normal Normal Normal Dry Dry Dry 1995 Dry Normal Normal Normal Normal Normal 1996 Normal Normal Normal Normal .Normal Normal 1997 Normal Normal Normal Normal Normal Normal 1998 Normal Normal Normal Normal .

However, the City's pumping capacity is limited. The City plans on adding two groundwater wells in the near Ettture and will need to add more wells as needed for connections within i[s sphere of influence. 6.3 Water Shortage Summary The City is not expected to have any water shortages in terms of wamr rights within the next 25 years. I-lowcver, the City is Currently limired by its pumping capacity, not its water supply. This analysis shows that even with a 50 percent reduction in water supply, the City still has sufficient water supply to meet its (orecas[ed demands without any water conservation.

DMM ]0 is not analyzed because the tv[-(' City is not a wholesaler. ~. Assumptions used in the economic analysis for each DMM analyzed are described in Appendix F. Directly beneath each assumption is a brief description oC the rationale and/or supporting evidence for that assumption. Common assumptions for all DMMs aze that the value of conserved water is $1,206/AF, the real discount rate is 6.15 percent, and [he overhead rate is 13 percent. The real discount rate is ca]culated from the assumed real cost of money (8.67 percent) and the assumed long-term inflation rate (2.52 percent) using the precise conversion method (A&N Technical Services 2000, pg A-2). The economic analysis was performed using Microsoft® Excel 2003, a spreadsheet program. A separate, customized worksheet Cor each DMM is presented in Appendix F. Each DMM economic analysis spreadsheet calculates, on an annual basis, the number of interventigns and the dollar values of the benefits and costs that would result from implementing a particulaz DMM. Terms and formulas that are common to all the workshee[s are defined in Table 7-2.

The November 2005 rate of 50.91 per 748 gallons (see Tab1c 7-3) was used plus 52,471 per million gallons to treat the water when it becomes wastewater. Because 80 percent of ¢eatment costs aze attributed to flow, only 80 percent of the cost to treat the wastewaer was used. The remaining 20 percent of the wastewater treatment costs are associated with organic and solids loading. This equated to a total value of wa[er of 51,206 per acre-Feet. This calculated value for conserved water does not include the capital cost Eor improvements to the wasrewater tteaunem plant to recycle all of City's wastewater in the future if the City is not allowed to dischazge into the Russian River. Based on the total annual water savings calculated, it is estimated that the City maybe able to reduce the design flow Cor furum wastewater raeatment needs by G percent.

The item is on the agenda for this September 19 meeting for further comment and discussion by the City Council. The Agenda Summary Report for the August 15 meeting also attached the sections from the California Water Code requiring and governing the preparation of Urban Water Management Plans. LEGAL REQUIREMENTS FOR URBAN WATER MANAGEMENT PLANS Water Code §10642 contains the procedural requirements that the City must satisfy before adopting an update of the plan. It "encourages the active involvement of diverse social, cultural, and economic elements of the population within the service area prior to and during the preparation of the plan." It also requires the City to make the plan available for public inspection and to hold a public hearing before adopting or updating the plan. Prior to the hearing, notice of the time and place of hearing must be published once a week for two successive weeks with at least 5 days between the first and second publications. The City must also provide notice of the time and place of the RECOMMENDED ACTION: Review and provide any comments or questions regarding the draft Urban Water Management Plan and schedule hearing for adoption of plan.

After the hearing, the plan shall be adopted as prepared or as modified after the hearing. Consultants to the City have consulted with the Mendocino County Planning Department, the Mendocino County Water Agency and the Sonoma County Water Agency in preparing the plan. The City has sent copies of the draft plan to numerous public agencies and other interested parties and made copies available at the Civic Center, the public library and on the City's website. The list of agencies and other interested parties who were sent copies of the plan is attached as Attachment 1. An accompanying letter, included in Attachment 1, requested comments by September 15. Comments will be accepted at any time up to the time that the City conducts the required hearing. Staff will distribute comments and any staff discussion of them at or prior to the September 19 meeting. It is staffs' intent to carefully consider all comments and consult with the commenters prior to finalizing the plan for consideration at the noticed public hearing. Staff has a goal of conducting the required hearing at the regular City Council meeting of October 17, but the City Council may schedule the hearing at a different time if it determines that additional time is needed to fully evaluate and respond to all the comments received. The Water Code requires an urban water management plan to be updated at least once every five years on or before December 31, in years ending in five and zero. (Water Code §10621.) The City's plan was last updated on October 13, 2002. The plan must describe and evaluate sources of water supply, reasonable and practical efficient uses of water, reclamation and demand management activities. The components of the plan may vary according to an individual community or area's characteristics and its capabilities to efficiently use and conserve water. The plan shall address measures for residential, commercial, governmental, and industrial water demand management. In addition, a strategy and time schedule for implementation shall be included in the plan. (Water Code §10615.) Water Code Section 10630 states that the Legislature intends the level of water management planning to be commensurate with the numbers of customers served and the volume of water supplied. In other words, small systems do not have to engage in the same level of planning as larger systems. A system must have more than 3000 connections before a plan is required. (Water Code §10617.) The City's system is a small system among urban water suppliers required to adopt a plan. The elements of an urban water management plan are set forth in Water Code Sections 10631-10635.) The draft plan update is organized to comply with these requirements. In general, a plan update covers the next 20 years in five year increments and attempts to project over that time period the water system service area, its existing and planned sources of water, the reliability of its water supply, including in average, single dry and multiple dry water years, and the quantity of water projected to be needed to meet expected demand. If there are deficiencies in the quantity or reliability of the supply, the Agenda Summary Report Page 3 September 19, 2007, City Council meeting plan is supposed to propose means of addressing those deficiencies, including conservation. DESCRIPTION OF PLAN EVALUATION OF WATER DEMAND AND AVAILABILITY This summary is not intended as a substitute for reading the plan update itself, including the executive summary. The plan covers a number of subjects not addressed here, including limitations on the City's present treatment and pumping capacity, proposed demand management practices, the effects of low rainfall or drought conditions, groundwater basin information and opportunities for using recycled water. The draft plan update includes the current City boundaries and the sphere of influence proposed by the City/County tax sharing subcommittee as the service area projected over the next 20 years. (See Plan, Figure 2-2, p. 2-3.) Based on population projections supplied by Leonard Charles, it calculates the use of water within that service area. The plan identifies the City's water rights and sources available to serve that area and estimates the amount of water that will be needed to meet that demand. The plan anticipates that, at a 1 % annual growth rate, the City will reach build-out within its existing boundaries and a population of 17,992 'by the year 2015. It estimates a water demand at that point of 4,730 acre feet per year (AFY). The plan assumes that the City will annex its entire proposed sphere of influence within 20 years. Over that time, it projects the population within that area to reach 12,675 and a water demand of 3,332 AFY. Combining these two areas, it projects a total future water demand over the next 20 years of 8,062 AFA. (Plan, pp. ES-4 to ES-5.) It observes that this total demand is less than the City's right to divert up to 20 cubic feet per second (cfs) under its water rights permit. The plan converts the 20 cfs rate of diversion to approximately 8400 AFY. (Plan, p. ES-3.)' The plan states that the City's water sources currently include the Ranney Collector and Well Nos. 3 and 52 which draw from Russian River underflow pursuant to the City's appropriative water rights permit, and Well No. 4 which is classified as percolating groundwater. The City does not require a permit to use percolating groundwater. (See, e.g., ES-1 to ES-2.) It states that the City is currently undertaking a well siting study and that increased water demand will be satisfied by additional groundwater wells. (See Plan, ¶3.6, p. 3-6. See, also §3.10, p. 3-26.) Elsewhere in the Plan the 20 cfs entitlement is converted to 14,480 AFA, but this number is described as the "theoretical maximum." The Plan refers to the explanation in §3.10, p. 3-18, which states that the City will only use 8400 AFA, when it first puts the full 20 cfs to beneficial use. (Plan, Water Rights, p. ES- 3.) The theoretical maximum is derived by assuming a diversion of the full 20 cfs 24 hours/day, 365 day per year. In fact, the City will divert 20 cfs during its peak period of demand, which, in the past, has generally occurred in July. The 8400 AFA figure was derived by assuming the City would divert proportionally less water at other times of the year based on the City's historical pumping records. (Id.) The Plan recognizes that Well No. 5 is not currently included as a point of diversion under the permit and notes that the City has applied to add Well No. 5 as a POD under its permit. Agenda Summary Report Page 4 September 19, 2007, City Council meeting In Section 3.10, the plan update includes a preliminary analysis of the impact of reduced Eel River diversions on the City's water supply. The analysis was performed by Mr. Robert Wagner, a hydrologist and water rights specialist with the engineering firm of Wagner & Bonsignore. That analysis evaluates (1) whether, under the reduced diversions from the Eel River, sufficient water will be available in the Russian River below Lake Mendocino to meet the historic demand for water in the Russian River system, including the City's demand and (2) what effect it would have on water storage in Lake Mendocino, if the City diverted its full 20 cfs entitlement under its water rights permit. For the reasons previously stated, the analysis assumed that a diversion at 20 cfs under the City's permit would equate to approximately 8400 AFA. The analysis studied the 2004 amendments to PG&E's Federal Power Act license for the Potter Valley Project, which controls the diversions from the Eel River into the East Fork of the Russian River. It studied Water Resources Control Board decision D-1610 which establishes minimum flows in the Russian River below the Coyote Dam at Lake Mendocino. It used the actual diversions from Eel River and the flows measured at key gauging stations in the Russian River between 1961 and 2006. This data is presented in Tables 1-5 and Figures 1-10, attached to the report. Also attached are copies of the most important of the source documents relied upon in the analysis. Based on this review, the analysis predicts a 26%~ reduction in Eel River imports for power generation as compared to pre-2004 diversions. Without considering water rights, the analysis concludes that there is sufficient water in the Russian River system to meet the historic demands for water in the Russian River system and the future City diversions up to 8400 AFA in spite of these reduced Eel River imports to the East Fork Russian River. The analysis considered two scenarios for dry season (May through November) releases from Lake Mendocino, which it labeled Scenario A and Scenario B. Scenario A replicated historic releases from Lake Mendocino (up to 275 cfs). Scenario B reduced Lake releases so that, after river losses and diversions, the SWRCB Decision D-1610 minimum flow requirements were just met. Scenario B was predicated on the assumption that, historically, more water than necessary was released from the Lake. In both scenarios, there was sufficient water in the system to meet downstream demands on the Russian River, despite the reduced imports from the Eel River. However, water levels in Lake Mendocino were modeled as significantly lower due to the reduced imports (see Figure 6). Under Scenario B, late summer water levels would be approximately 6 feet lower than historical levels, on average. Scenario A late summer water levels were modeled as approximately 11 feet lower than historical levels, on average. Scenario B would require changes in how releases from Lake Mendocino are regulated by Sonoma County Water Agency (SWA), which has administrative control of releases from the lake. According to Mr. Chris Murray, a hydrologist with SWA with whom Mr. Wagner consulted, greater efficiency in operation of lake releases is achievable. Agenda Summary Report Page 5 September 19, 2007, City Council meeting In each scenario, as reflected in Figures 8 and 10, a doubling of City diversions to approximately 8400 AFA could result in a lower average lake level in Lake Mendocino of approximately 1 foot under Scenario A and a negligible amount under Scenario B. The analysis assumed that any increased water extractions from the groundwater basin by the City would result in lower lake levels. The analysis points out, however, that the impact of the groundwater extractions may not result in an immediate reduction in stream flow. The stream flow reduction due to increased pumping in the dry season may well not be manifested until the following winter. In that event, sufficient water would be available from winter precipitation to replace the extractions. As a result, even the small predicted lake level reduction would not occur under those conditions. After the draft plan was circulated, the City Attorney asked Mr. Wagner to address the issue his analysis does not consider; namely, whether or not the City will infringe on Lake Mendocino storage rights that may be senior to the City, if the City exercises its full 20 cfs diversion right as authorized by its water right permit. Both the SWA and the Mendocino County Russian River Flood Control and Water Conservation Improvement District ("Flood Control District") have permits to the water stored in Lake Mendocino in the winter and released in the summer. Since the amount of water being imported into Lake Mendocino, especially in the spring and summer, is being substantially reduced, the City Attorney wanted Mr. Wagner to analyze whether increased diversions under the City's permit to its full 20 cfs entitlement would infringe on the water rights of the Flood Control District, the SWA, or other water rights which are senior to the City's. Attached as Attachment 2 is his response. In summary, he concludes that current city diversions from Russian River underflow of approximately 6.833 cfs in the summer can be met from: 1. pre-1949 water rights (2.8 cfs), which are senior to the rights to project water held by SWA and the Flood Control District, and 2. the City's contract with Flood Control District for project water (4.033 cfs). The City has a water supply contract with the Flood Control District (FCD) for 800 AFY of project water. Mr. Wagner estimates that if the City used the 800 AFY for 100 days in the summer, it would equate to a diversion of 4.033 cfs during that time. This contract right in combination with the City's pre-1949 right totals 6.833 cfs. In addition, Well No. 4 produces approximately 1.75 cfs year round, giving the City as much as 8.583 cfs to meet current demand without infringing senior water rights held by SWA or the FCD.3 As to future diversions to put the remaining water under the City's permit to beneficial use, Mr. Wagner concludes that the future diversion of up to 11.4 cfs will come from groundwater extracted from the Ukiah Valley groundwater basin, and that increased future extractions from the groundwater basin are not an infringement on East Fork water released from storage in Lake Mendocino. Mr. Wagner notes that additional non-project water may be available in the summer to pump under the City's permit,. including water from the West Fork, East Fork, infiltration of direct precipitation, groundwater accretion and return flow. His response does not rely on these additional sources. Agenda Summary Report September 19, 2007, City Council meeting Page 6 For these reasons, he concludes that the City can meet its present and future water demand without infringing on SWA or Flood Control District rights to project water, not already included in the City's current contract. He indicates that he is completing an analysis of other water rights that are senior to the City's 1954 priority date, and should have the analysis complete before the City Council is asked to adopt the final urban water management plan. At the September 19 meeting, staff will attempt to answer questions from the City Council and members of the public and will take comments back to the consultants for additional analysis, if needed or requested.

Date: September 14, 2007 Re: Potential Infringement of Water Right Priorities on Releases from Storage in Lake Mendocino by the Full Exercise of the City's Water Right Permit. You asked us to address the question of whether or not the City will infringe on Lake Mendocino storage rights that may be senior to the City, if the City exercises its full 20 cfs diversion right as authorized by its water right permit. The analysis that we prepared for the Draft Urban Water Management Plan concluded that there was sufficient water in the Russian River system to meet the historic demands and the future City diversions in spite of the reduced Eel River imports to the East Fork Russian River, a source of water for Lake Mendocino. We evaluated two scenarios for dry season demands downstream on the Russian River: A) lake releases are equal to historical releases (up to 275 cfs) and B) lake releases can be decreased from historical rates so that, after river losses and diversions, the Decision 1610 required flow rates are just met. In both scenarios, there was sufficient water; however lake levels were predicted to be significantly lower in Scenario A than in Scenario B. The difference between Scenario A and Scenario B is the underlying assumption that releases to satisfy D-7610, in the past have been inefficient. In essence Scenario B is a management change resulting in a more efficient lake operation. According to Mr. Chris Murray of the Sonoma County Water Agency such efficiency in operation is achievable. In each scenario our analysis concluded that the City's diversions in the past have no impact at all on lake levels in Lake Mendocino and do not result in a reduction of water in storage. Any predicted lake level changes based on past releases and reduced imports are a function of changed regulatory constraints. The City's water right permit is for 20 cfs to be diverted from Russian River underflow. The City's points of diversion are located downstream of Lake Mendocino and the water that is diverted or extracted includes water from the West Fork, East Fork, infiltration of direct precipitation, groundwater accretion and return flow. The City does not divert from the lake, nor is it reliant on the water supplied from the East Fork to satisfy diversions under its water right permit. 444 A6rfh nad.srieer, Suile,325, .Saaunierva, Ca!lfomfa 95879-0228 Ph: 916-44 1 6450 ~ 97G-448--',&'i~ Mr. David Rapport September 14, 2007 Page 2 A portion of the City's water right is derived from apre-1949 right for 2.8 cfs which can be satisfied from the East Fork of the Russian River. Water released from storage in Lake Mendocino and the source of the water to satisfy the water rights for the lake is restricted to the East Fork. The relative priority to the water of the East Fork between the City and the Flood Control District is first to the City for at least 2.8 cfs and second to the District for amounts in excess of the City's pre-1949 water right. The City also has a contract with the Flood Control District for 800 acre feet (assuming the contract was exercised every year for 100 days, the contract amount would equate to a rate of 4.033 cfs or about the same amount that the Ranney collector diverts). Therefore, the City's diversion of 6.833 cfs from the East Fork would constitute no infringement on the senior rights of the Flood Control District. The City's well number 4 pumps about 1.75 cfs of groundwater from the Ukiah Valley groundwater basin. Consequently, the City has access to, at least, 8.583 cfs of water based on water rights that are either senior or equal in priority to the District or available from percolating groundwater. The remainder of the water to be diverted by the City in the future, about 1 1.4 cfs, will come from groundwater extracted from the Ukiah Valley groundwater basin (whether or not the groundwater is subject to SWRCB jurisdiction). With respect to priority between the City and the Flood Control District, the District's water right permit does not authorize it to divert from the Ukiah Valley groundwater basin, or from the West Fork, or any source other than the East Fork Russian River. We made an estimate of the flow at the forks and at Hopland absent storage regulation by Lake Mendocino and as reduced by the 2004 amended FERC license for Potter Valley Project. The area between forks and Hopland is roughly the area containing the Ukiah Valley groundwater basin. The average June and July flow at the forks flow would be about 95 cfs. The average July flow at Hopland would be 63 cfs. In some years the flow would be substantially greater and some years less. For example, at Hopland, 5 of the 46 years modeled, the surface flow would have been zero in July. June flows would average 85 cfs with zero flow in 5 out of 46 modeled and August flows would average 88 cfs with zero flow in 2 out of 46 years. September flows would average 156 cfs and May flows would average 202 cfs. It is important to restate that the City's future diversions will come from groundwater extractions and will not be dependent on the surface flow at the forks, since the City will be able to rely on water stored in the groundwater basin. The cursory evaluation of unregulated flow at the forks and at Hopland is an indicator that the groundwater basin recharges every year without the regulated storage releases from Lake Mendocino Additional evaluation of groundwater levels in the Ukiah Valley will need to be made to identify patterns of seasonal changes in groundwater storage. The City's future extractions from the groundwater basin, are not an infringement on the East Fork water rights. The City's permit was issued with a diversion season of January 1 to December 3 l and is unconstrained by the D-1610 minimum flow conditions. The D-] 610 flow conditions adopted in ~' il~.,UT1C'Fr`:~O]lS1c~T1 ](>I"e ~~., ~,. Mr. David Rapport September 14, 2007 Page 3 1986, included an accounting of the existing water rights on the Russian River as of that time. The City's permit, with a priority date of 1954, was issued with the finding that there was 20 cfs of water (Russian River Underflow) available to satisfy the demand. Additional questions regarding the relative priority of the City to Russian River Underflow will be addressed as we continue to evaluate the water right priorities that are senior to the City's water right and have a common source. We have compiled most of the data and we expect to finalize that work in the next three to four weeks. We are also updating the water level data we previously compiled to evaluate the seasonal and long term trends in changes in groundwater storage. Please contact me if you have any questions.

City Council: Mayor Mari Rodin Phil Baldwin Doug Crane John McCowen Benj Thomas City Manager Candace Horsley Re: City of Ukiah's Draft 2005 Urban Water Management Plan (UWMP) After review of the City's 2005 UWMP, I am providing the following extended comments. 1. Reason For Extended Comments One of the mandated purposes of LAFCO is to °make studies and to obtain and furnish information which will contribute to the logical and reasonable development of local agencies in each county and to shape the development of'local agencies so as to advantageously provide for the present and future needs of each county and its communities. " (G.C. 56301) Making studies would include the review of other agency studies and reports, such as the City's Urban Water Management Plan, for the purpose of using that information in LAFCO studies or for the purpose of responding to those studies while in development so as to indicate LAFCO interests or concerns. If LAFCO is to use this infotma±ion for fut~.rre SOI/MSR studies, annexation studies or ether such reports, providing comments at the development stage of the UWMP would be an important effort for the record. 2. Current Information The UWMP only provides use or consumption information through 2004. It is now October of 2007. Clearly the City has information for 2005, 2006 and most of 2007. I realize that this document is in fact the 2005 UWMP that was due by December of 2005, but given that it was not completed by the statutory date and it is being reviewed by the public and agencies now, why not provide the most current information available? It would seem that it would be in the best interest of the City to do so, given the potential issues around proposed developments and lawsuits. It would also seem that the City has a fiduciary duty to do so. Comment letter for City of Ukiah's 2005 U WMP Local Agency Formation Commission of Mendocino County--LAFCO 3. UWMP-Foundational Plannin¢ Document Urban Water Management Plans can serve as an important source for updating General Plans. Conversely, General Plans can be and should be source documents as the City updates the UWMP. These two planning documents are linked and their accuracy and usefulness are interdependent. As well, the City's SOI determination by LAFCO is linked to the General Plan and thus to the UWMP. UWMPs also can be useful planning documents for Municipal Service Reviews; proposed annexations, Master Service- Capital Improvement Plans and other such processes. 4. SB 610 and SB 221 The California Department of Water Resources also views the UWMP as a foundational planning document for compliance with SB 610 and SB 221. These two statutes are companion measures which seek to promote more collaborative planning between water suppliers and planning agencies (cities-counties). Both identify the UWMP as a planning document to be used by water suppliers to meet the standards set forth in both statutes. The City may need to meet the requirements of SB 610 and SB221 for the Brush St. Triangle development and proposed annexation to the City. The City should review the UWMP to see if the supply and demand analysis in the UWMP meets the requirements of SB610andSB221. Any proposed development immediately adjacent to the City (Lovers Lane, Masonite) may well use elements of this document to draw conclusions for support of the proposed development (e.g. UWMP statements about the ground water basin and available water). This being the case, it is critical that the City's UWMP be rigorously developed and that it accurately describes the true condition or circumstances of water availability from the Russian River and from the Ukiah Valley Groundwater Basin. 5. Other Related Documents It is instructive to review previously published documents (General Plan, 2002 UWMP, Water Rights Permit Extension Application, Proposed UVAP, etc.) for purposes of understanding consistency of presentation of information, to determine any changes that have occurred over time and to understand potential impacts from other planning documents. As well, it can be instructive to review the cited studies in the Draft UWMP (DWR 118, USGS-1985) and some other non-cited documents (Sommazstrom-1986, LAFCO Interim Water Report-2007, LAFCO Policy and Procedures, etc.) for understanding parts of the discussion that occur in the 2005 Draft UWMP. Some of my comments will cross reference these other sources. 6. Citv's Sphere of Influence (SOI) A sphere of influence is defined as a "plan for the probable physical boundaries and service area for a local agency, as determined by the commission." (G.C. 56076) Comment letter for City of Ukiah's 2005 UWMP 2 Local Agency Formation Commission of Mendocino County--LAFCO City's General Plan In 1995, the City adopted its present General Plan. The General Plan (including the SOI) was adopted after a three yeaz effort, review and advice of a Citizens Advisory Committee composed of individuals from within the City and from azeas adjacent to the City. This statement is on page I 1 of Section II of the City's General Plan: "One of the components of the General Plan is an identification of the Sphere of Influence. The Sphere is a boundary that represents the ultimate City limits for the City of Ukiah. The Sphere of Influence is proposed in the General Plan bur must be approved by the Mendocino County Local Agency Formation Commission. LAFCO is an independent body created in State law. The Commission has the power to approve or deny annexations, incorporations, or formation of most special districts. LAFCOs also must approve spheres of influence for all cities and special districts. A city cannot annex land that is not a part ofits sphere. " (Underline-added) Before the 1995 General Plan was adopted, the City's sphere was quite lazge. The General Plan stated the following: "When the 1981 version of the General Plan was adopted, the sphere of influence was basically the entire Ukiah Palley. During the process of preparing the 1992 revision to the General Plan, it was determined that this boundary was too large for a sphere of influence. "Therefore, in 1995 when the City adopted the General Plan it adopted the SOI that was proposed in the General Plan which is considerably reduced over the 1981 version. This eliminated 1981 SOI is similar to the area that the City is proposing as the Place of Use for extension of its water rights permit. Post adoption of the General Plan, the City never approached LAFCO for the purpose of approving their sphere. The City is now in the curious place of having eliminated its 1981 sphere while not having its 1995 sphere approved by LAFCO. In essence, the City is in SOI limbo land with no approved sphere. Had the City applied immediately to LAFCO in 1995, LAFCO would have approved the sphere as adopted in the General Plan. However, since that time, LAFCO law has changed, requiring a much more rigorous approach and review before a SOI is determined. (See G.C. 56425 & 56430) Recent Discussions on SOI In recent months, the City Council has held discussions on a SOI not indicated in the General Plan. These discussions were in context of a proposed Tax Shaze Agreement with the County, proposed future annexations (Brush St. Triangle) and proposed development in the County adjacent to the City (Masonite, Lovers Lane). And, in context of a renewal application to the State for its expired Water Rights Permit. In documents circulated by the City, (water rights permit, Draft UWMP), the City identified this "discussed sphere" as a "proposed sphere." On page 2-3 the UWMP provides a map labeled, "Figure 2-2 City of Ukiah Sphere of Influence Map (Map provided by Wagner and Bosignore). The territory depicted on this map is considerably different than the territory for the SOI that is depicted on page 6 of Section II of the General Plan. This UWMP map may depict a "discussed sphere" by the Council but it is not a "proposed sphere", either by General Plan determination or by application to Comment letter for City of Ukiah's 2005 UWMP Local Agency Formation Commission of Mendocino County--LAFCO LAFCO. In point of fact, the "discussed sphere" becomes a "proposed sphere" when the City actually makes application to LAFCO to "develop and determine" it's SOI. LAFCO's Policv on Sots LAFCO's policy provides that: "Territory will not be considered for inclusion within a city's sphere of influence unless the area is included within the city's general plan land use or annexation element. " (Page 62) Therefore, the lazQest sphere that LAFCO could consider for the City would be that which was reviewed and considered in the General Plan. A general plan amendment would be required for a proposed sphere that was lazger than that included in the adopted General Plan (determination of a smaller sphere would not require an amendment). Plus, completion of the MSRs (general and regional-fire, water, and sewer) will be required before any determination can be made by LAFCO. Water Interim Report In February of 2007, the Commission adopted an Interim Report regarding water in the Ukiah Valley/Russian River Watershed. Adoption of that report included the understanding that given the current conditions and circumstances and provided that those conditions continued, it would be difficult to justify a sphere for any water provider agency, including the City of Ukiah, greater than its presentjurisdictional boundaries (i.e. a co-terminus sphere). This direction of the Commission is an important indicator to the City as to its potential SOI. The Commission's direction is much different than what is presented in the UWMP or the City's Water Rights extension application to the State. It is the more likely SOI given present Valley circumstances for water. 7. Why is the Sphere Discussion Important? On page ES-5 of the UWMP the following statement is found: "The City has plans to annex land within its sphere of inRuence within the next 20years. The population within the sphere of influence is expected to increase from approximately S, 675 to 12, 675. This is an increase of 7, 000_ At 2.86 people per connection, which is the average number of people per connection for the City, the total number of connections for a population of I2, 675 is 4, 432. The City's average water use per connection is 0.73 AFY. Using this same average water use for connections within the sphere of influence, the water use is 3,235 AFY. Including the 3 percent unaccounted for water loss, this value increases to 3,332 AFY. !t should be noted that some ottee connections within the Citv's s hn ere of influence are served by other water districts. This UWMP assumes that in the next 20 years, these connections will eventually be served by the City's water svstem " (Underline, bold-added) This is not the only thing assumed in these statements: (I) A sphere of influence is assumed that is not part of the record of the General Plan or an application to LAFCO; (2) Annexations are assumed as occurring; it is not a given that they will and; (3) The City assumes that it can better its position as to water use (and thus its water rights permit) at the cost of harm to other agencies. All the verbiage about population, connections, and use is just a smokescreen to these assumptions and would otherwise be useless and non-pertinent without these assumptions. As Comment letter for City of Ukiah's 2005 UWMP 4 Local Agency Formation Commission of Mendocino County--LAFCO indicated, these assumptions are not necessarily valid or accurate to the present circumstances of the City. 8. Annexations Except for hillside lands in the western hills, the City is generally surrounded by areas which include urban level development that is served by independent fire, sewer and water districts. For the City to annex lands to the north or south of the City would require detachment of these lands from these districts. As indicated in the quoted passage above, this seems to be the City's plan. This would occur at great harm to those districts. The City's General Plan was adopted 12 years ago without a subsequent request to LAFCO for approving the proposed SOI. Airport Pazk was the last City annexation (about 25 years ago). This area has yet to be fully developed and serviced by the City. With the exception of the Brush SL Triangle, no landowners have come forward seeking annexation for two decades or so. The 90 acres or so of the Brush St. Triangle is the one area contiguous to the City that could be annexed without much harm to other service agencies. Although the City has received a letter of request for annexation from the owners of the Brush St. Triangle, it has not provided an annexation application to LAFCO (there are valid reasons for this). If annexation occurs, as with Airport Park, it could take many years for this area to be fully developed and serviced by the City. The potential demand for services could well preclude the City's ability to annex other azeas. In making its decisions LAFCO must understand the potential for harm to others and moderate its decisions accordingly. Regarding SOIs, LAFCO's policies indicate: "Inclusion of territory within an agency's sphere of influence does not assure annexations of that territory into that agency. There are a number of factors the Commission must review before it can approve an annexation. "One of those "factors" is the potential impact on affected agencies and other social and economic communities. Any annexation that LAFCO would be willing to approve is subject to the review and approval of voters and landowners via a prescribed protest process and; depending on the outcome of the protest hearing, possibly an election process. In the past, landowners and voters from areas immediately outside City boundaries have emphatically indicated that they were not interested in annexation. Given all the indicated circumstances, it is not predictive that the City will annex this area in the next 20 yeazs. As indicated previously, it is not even predictive that this azea will be included in the City's SOI. At the time of a SOI application from the City, LAFCO could, via a "sense of the community" survey, proactively seek an understanding from these landowners, voters and agencies as to their interest in being included in the City's SOI and possible future annexations. This effort would be consonant with the general provisions of G.C. Section 56428 which allows persons or agencies to seek amendments to the SOI. Such an effort could potentially provide clear direction to the Commission and the City for this issue and would be the best approach for determining the future possibilities for annexation. Comment letter for City of Ukiah's 2005 UWMP Local Agency Formation Commission of Mendocino County--LAFCO Based on the City's track record for annexations for the past twenty years, predicted annexations for the next twenty years would be zero; not the area described in the passage above. The UWMP should not be so casual about the possibility of annexing this territory and should more realistically explore all of the circumstances and issues as to the City's potential SOI and annexations. 9. Harm to Others-.Water Code No Iniurv Rule The "no injury" rule is shorthand for several sections of the Water Code related to changes in existing rights (See W.C. 1700-1707). There is a general rule that applies to all water right changes; water right changes cannot cause'`injury to any legal user of the water involved." (W.C. 1702) In general, California water law protects senior water users from junior diverters while protecting junior water rights holders from the expansion of senior water rights. For example, junior water rights holders could be harmed if senior water rights holders should increase the amount of water they divert under their senior water priority. Generally, the Water Code contains wording that protects prior users. Section 1702 indicates "any legal user." This is significant to the City, given that: (1) The State has determined that the Russian River is fully appropriated; (2) The natural flow of the River is being fully used; there is no extra water and; (3) The City in fifty years has not beneficially used the amount of water available in its permit. There are a number of downstream users (both in time and in place) who could be harmed if the City substantially increased its use under its permit. If the City's Water Right Permit change of Place of Use could adversely affect the availability of water for the downstream users (regardless of their priority), this change may not be allowed under the "no injury' rule. The UWMP should adequately explain and examine this possibility and the harm to existing service providers within territory the City wants to put in its Place of Use and claims it will annex. Willow CWD's letter to the City protesting the placement of Willow's territory in the City's proposed Place of Use is an early warning to the difficulty of annexations for the City and potential complaints as to harm or injury. 10. Citv's Water Right Permit Extension According to Table 3-2 (page 3.3) in the UWMP, the City consumed a total of 4,131 AF in 2004; of which 976 AF was groundwater, which the City considers to be percolated groundwater. Thus the actual amount consumed under its Water Rights Permit was 3,155 AF. The City is projecting that by 2010 it will be using 1,895 AF of ground water. Additionally, it has a contract for 800 AF from Russian River Flood Control. The City has had a number of extensions of its permit since it was received: "The City's Water Right Permit has been assigned number 12952 and has a priority date of 1954. Each water rights permit issued by the State Water Board gives the permittee a set amount of time to actually use the water authorized for diversion under the permit. The Comment letter for City of Ukiah's 2005 UWMP Local Agency Formation Commission of Mendocino County--LAFCO City was origlnal[y issued the permit in 1961 and the City had 10 years to put the full amount of water to beneficial use. That time has been extended several times. The latest extension gave the Ciry until December 31, 2000. Prior to that date, the Ciry fzled another Petition for Ezlension of Time to put the water to beneficial use. The most recent request asks to extend the lime to 2015. " (Page ES-3 of UWMP) The count as indicated in this paragraph suggests that there have been at least four or five extensions, including the latest request. "The face value of the City's Pre-1949 and Pos[-1949 appropriative water rights is approximately 14,480 AFannually". (page 2-7) As indicated above, the City has had multiple extensions of time for proving its permit. In fifry plus years of holding its water rights the City is beneScially using (as of 2004) approximately 22% of its appropriative water rights. Based on projections of increased groundwater use and its contract with Russian River, it seems that the City has plans to use even less. Water rights can be lost through non-use (see Water Code Section 1241). The State in review of the Ciry's request for extension and change to its permit can make one of three possible decisions: (1) IC can grant all of the requested changes; (2) It can require the City to go to license for present use and circumstance or; (3) It can modify the City's request as to place of use, amount of use and other issues. The UWMP assumes that the State will allow an extension of time, continued water rights for the full face value of 14,480 AF and allow a substantial increase of territory for the POU. [f the City has communications from the State indicating that this is a probability; then this would be good information for the UWMP. If not, a realistic discussion of these possibilities should be provided in the UWMP. 11. DWR Bulletin 118 and the UWMP The DWR Bulletin 118 for the Ukiah Valley Groundwater Basin (Number 1-52) is five pages in length; not much information for the complexity of circumstances of this basin. The UWMP on page 3-3 indicates that Bulletin 118 "concludes" that there is 90,000 AF of potential groundwater in the Ukiah basin. Bulletin 118 provides some "estimates" taken from the USGS report (Farraz 1986); they are not conclusions. These "estimates" aze simply arithmetical calculations based on a series of assumptions. Assumptions Example (1) Assume an azea of 20 squaze miles for the aquifer, (2) Assume 100 feet of uniform depth, composition, compaction, permeability, inflow and outflow of the aquifer; (3) Assume 8% uniform yield; (4) Assume a fudge factor and; (5) Assume the math result is the estimate. The fudge factor Farraz used was based on anecdotal reports that water was not found in the first fifteen feet of the aquifer; thus there was not 100 feet of storage. Math Example-Fun With Numbers (Values used are taken from the bulletin): 20 sq. miles X 640 acres per squaze mile X 100 feet of depth X .85 storage X .08 of yield equals 87,040 AF and Comment letter for City of Ukiah's 2005 U WMP Local Agency Formation Commission of Mendocino County--LAFCO -you have an estimate of 90,000 AF. There have not been field studies that "ground truth" this "estimate" which otherwise should be known as an exercise in fourth grade math. More Fun With Numbers Based on anecdotal information, Farrar assumed that the first fifteen feet of the basin understory would not store water. This assumption was before gravel extraction and undercut of the streambed occurred. Present estimates aze that the streambed has been undercut by 15 to 20 feet. This could certainly alter the storage opportunity in the aquifer. Obviously, the Farrar report does not include information from the past 25 yeazs of development and consumption. Present anecdotal information indicates that water once found at 20 feet is now found at 50 to 60 feet. Using that information in Farraz's computations would significantly alter the results of the math exercise: New Math Example: 20 sq. miles X 640 acres per square mile X 100 feet of depth X .65 storage X .08 of yield equals 66,650 AF; a significant difference with the change of one variable. How many other variables are there that we don't understand? How simplistic is it to use an arithmetical exercise in lieu of real knowledge? Conclusions- Not Estimates The one conclusion that Bulletin 118 emphatically provides is: "There is not enough data available to provide an estimate of the basin's water budget. " Therefore, the Groundwater Budget for the Ukiah Valley Groundwater Basin was designated as Type C. The Groundwater Budget is simply the following formula: Inflow minus Outflow equals Change in Storage (presuming that the actual storage of the aquifer is known). A groundwater basin can have one of three designations by the State: (1) A Type A budget indicates that much of the information needed to characterize the groundwater budget for the basin is available; (2) A Type B budget indicates that enough data aze available to estimate the groundwater extraction to meet local needs and (3) A Type C budget indicates a low level of knowledge of anxof the budget components for the basin. A Type C designation indicates that we do not have the elementary knowledge about the Groundwater Basin that is needed for the purpose of making use decisions. 12. Need for Groundwater Basin Studv The USGS report was published in 1985; presumably the gathering of information occurred some time in advance of the publication. It has been nearly 25 years since that effort was made. In that time, numerous new wells for in•igation and for development Comment letter for City of Ukiah's 2005 UWMP Q Local Agency Formation Commission of Mendocino County--LAFCO have been drilled along with increased opportunities for pollution. Any information in those reports having to do with the Water Budget is almost certainly behind the curve. Dama¢e to the Groundwater Resource-Willful Ignorance In some areas of the state, the groundwater resource has been harmed by high rates of extraction, inadequate recharge, contamination as a result of land use practices, and in some cases subsidence. This occurred because of the refusal to understand the true values of the aquifer and the impact of growth decisions on this resource; so the resource was destroyed because of willful ignorance. Past conventional (but erroneous) wisdom, was that anything dumped on the ground would be cleaned by flowing through the ground. Thus, much present contamination is from indiscriminate but accepted past practices of handling chemicals and disposing of wastes. Excessive development using septic tanks is another medium for contamination. Illegal meth lab waste is one of the more horrific possibilities for contamination. Ofren this waste is disposed via septic systems which can provide a direct connection to the aquifer. Every new development becomes a potential discharge point for contamination and/or an elimination of rechazge area. Depending on the aquifer, it can take decades to hundreds to thousands of years for water to move from a recharge area to a dischazge azea. Therefore, it may take years before contaminants aze detected; often detection occurs afrer a community well has been polluted. Once contaminated, aquifers can remain contaminated for decades to hundreds of years. There are tremendous costs involved in cleaning or remediating an aquifer. As in most things, the best cure is prevention. Management of Groundwater Management of groundwater resources is more complex than management of surface resources. Once developed, drained, or damaged it is extremely difficult to rebuild and recharge an aquifer. We have no idea of the true circumstances of our Groundwater Water Basin; yet, planning for development is occurring that is assuming that plenty of water will be available and that conditions and circumstances are fine. The City of Ukiah must provide realistic information about the Ukiah Groundwater Basin by conducting the requisite field studies. This must be done before any new development is allowed and before greater dependency occurs for the use of this resource. Ouestions to Be Asked There are many questions to be answered about our groundwater basin, such as: • What is the actual storage of the basin? • What is the recharge rate? • What is the safe yield? • How long will it take to extract the water? • What is the present quality of water, (i.e. contamination and natural occumng chemicals)? Comment letter for City of Ukiah's 2005 UWMP 9 Local Agency Formation Commission of Mendocino County--LAFCO • How do you protect the quality of the groundwater? • Does the recharge rate need to be managed? • What has been the effect of gravel extraction from the streambed and gravel mining adjacent to the streambed? • Do we need a groundwater management plan? • What about overlying property rights to groundwater? • Should we go forward with any development until we have answers to these questions? • And a whole lot more that a more technically aware person would know to ask. The UWMP indicates thaf the City is planning on using ever more groundwater for its needs. The City cannot assume that water is there or will be there on the basis of a Shazam estimate. A Groundwater Basin Field Study is critically needed. Here is an idea: Partner with the Mendocino County Water Agency and the water districts to fund and conduct a complete Ukiah Groundwater Basin Study. Do not go forward with any planning processes (e.g. City's UWMP, UVAP, and Water Element for County General Plan) or approve any major development until we clearly understand the present circumstances and future possibilities for this precious resource. 13. Other Studies Sommarstrom In September of 1986, Sazi Sommazstrom, Ph.D. published a report entitled, AN INVENTORY OF WATER USE AND FUTURE NEEDS IN THE RUSSIAN RIVER BASIN OF MENDOCINO COUNTY. This report was prepared for the Mendocino County Flood Control and Water Conservation Improvement District. The number one recommendation that Dr. Sommazstrom made was: "A specific ground- water study of the Ukiah (/alley is needed to determine the relative amounts of surface andground-water currently used, irrigation recharge rates and movement, and the safe yield of the ground-water basin. "That study was never done. As noted above, since that time many new irzigation and development wells have been drilled and much gravel mining has occurred. Citv's 2002 Update to the UWMP The City's 2002 Update to the Urban Water Management Plan in discussing the issue of underflow versus percolated groundwater indicates: "Any attempt to resolve the issue may need a complete geo-hydrologic investigation of the area. " (page b) It further states: "The preparation of a groundwater management plan is not merited at this time because of the modest increases in demand and the low potential need for groundwater." (page 7-underline added) Yet the 2005 UWMP update indicates that the. City expects to double its use of groundwater by 2010 (a mere three years from now). It is cleaz that the City is aggressively moving towards groundwater use; it should just as aggressively move toward completing the needed studies. Comment letter for City of Ukiah's 2005 UWMP 1 ~ Local Agency Formation Commission of Mendocino County--LAFCO The inescapable conclusion for the Ukiah Groundwater Basin and its present circumstances is that field studies are required before increased groundwater extraction occurs. Given that the City plans on increasing groundwater extraction to nearly 2,000 AF by 2010, it would seem that the City would make a major effort to perform these studies. At the very least the City should not be representing in the UWMP that ample water is available without making these studies. 14. Is There Water in the River or is it Shazam Water Too The City's appropriative Water Rights Permit has a face value of 14,480 AF. According to the UWMP, in 2004, the City used 3,155 AF of its appropriative rights. On the basis of its paper water rights, it would appeaz that the City has ample water. But, is there water in the River? The City is aggressively moving toward the use of "percolated groundwater" for its needs. The City also entered into a contract for 800 AF from Russian River Flood Control and Water Conservation Improvement District in December of 2004. Given these two circumstances, it begs the question as to why the City is purchasing water from a wholesaler and using more and more groundwater instead of using water from its appropriative rights. If water is there for its appropriative rights, why bother with drilling more wells for percolated groundwater and with contracts from wholesalers? The answer appeazs to be that the water is not physically available. If that is not the answer; why contract for 800 AF from Russian River and prevent some other needy agency (e.g. Redwood Valley) from having the water? Natural Water and Crisis Appropriative water rights apply to naturally available water in a stream or other body. In 1998, the State determined that the Russian River was fully appropriated. For the past 75 years or so, users of water along the River have been consuming water from the Eel River brought to the Russian via the Potter Valley Tunnel. This water is not natural flow water and is not part of appropriative water rights provided for the Russian. Due to regulatory issues that water was mostly not available this year. The past 25 years have seen increased consumption from grape irrigation and development. Major development is being discussed for the Valley, faz beyond anything that has occurred previously. The 2005-2006 winter was a wet winter; followed by a mildly dry winter in 2006-2007. This dry year along with the reduction in flow from the Eel has required water use control and water conservation measures from the water suppliers and for users. If one mildly dry year that followed a wet yeaz puts us in a use reduction conservation semi-crisis mode, what will be the effect of a series of dry yeazs (normal for California) or the complete shut down of the Potter Valley Tunnel? What will be the effect of such circumstances if increased development occurs? r**** Comment letter for City of Ukiah's 2005 UWMP 11 Local Agency Formation Commission of Mendocino County--LAFCO Conclusion• The UWMP does not provide accurate or complete information, misrepresents actual conditions or circumstances, makes assumptions that aze not supportable and in general provides an inaccurate picture of water circumstances. Recommendation: Understand that the UWMP is a foundational planning document. Do not see this process as a passive exercise. Do not practice willful ignorance. Conduct the needed studies. Partner with the County and districts on the Groundwater Basin Study. Take a Leadership role on water via the UWMP. The 2007 LAFCO Water Interim Report used the term "train wreck" to indicate our present water circumstance in the Valley; perhaps not the best metaphor for water but it does indicate the problem. The City can take a leadership role on water issues by leading the discussion in its UWMP and by seeing that the needed studies are completed.

The City has no right to pump water that has been stored in lake Mendocino and later released into the East Fork RR. Page 3.77 -General Comment This analysis assumes that shortfalls in available t ~ supply from natural flow and Potter Valley imported water are made up from Sonoma County Water Agency supplies stored in Lake Mendocino. Ukiah The 800 AF that the City can purchase from MCRRFCWCID is listed as project water in this UWMP. No further action will be completed on this comment. The City agrees with this comment as it pertains to the East Fork Russian River. The City has no intention of using stored water from Lake Mendocino. No further action will be completed on this comment. The future Ukiah extractions under its water right permit will come from The Ukiah Valley groundwater basin. SCWA's permit 12947A is limited to water originating in the East Fork Russian River. SCWA comment does not make it clear why it considers the future extractions by the City to be project water City of Ukiah Urban Water Management Plan does not have a contract with SCWA River Underflow, Jan 1 to December 31 without a bypass condition. It is not necessary for Ukiah to enter into a contract with SCWA to extract water from the groundwater basin (or the subterranean stream). During very dry years, same of the City's water use can be made under its contract with the Flood Control District, to the extent that it is necessary, The contract, for 800 acre feet, is roughly 4 cfs during the dry season.

Wagner background and qualifications Purpose of Workshop: Discussion of the Hydrology portion of the Urban Water Management Plan Items for Discussion A) What did we model and why? B) future supply limitations C) Ukiah's water rights D) Regulatory constraints for perfecting Ukiah's water rights E) Management constraints and regional water planning. F) Public Comments on UWMP Item A We developed a spreadsheet model to predict the impacts on water supply and operations of Lake Mendocino due to reduced Eel River imports based on the FERC E-5 condition (2004). The model evaluates historic releases from Lake Mendocino, as an indicator of historic demand. The model assumes that D-1610 applied for the entire period of record, not just since D-1610 was implemented in 1986 and that the E-5 condition was in place during the entire period of record (1961-2006) The model's output is end -of- day water surface elevation enabling a comparison of future conditions to past conditions. The City's historic demand is included in the historic evaluation. The model's prediction of lower lake Levels in the future is not connected to or affected by the increased pumping by the City. We estimated return flow from the City's pumping based on wastewater discharge data and distributed the return flow in the future in the same pattern that it occurs now. The City's future demand was based on a peak pumping demand of 20 cfs which results in an annual demand of 8400 acre feet. We assumed that the City's future demand would be satisfied by groundwater extractions. While acknowledging that there will likely be a time lag between groundwater extractions and any stream flow reduction, we ignored the time lag Item B Future water supply is based on the past hydrologic record adjusted to account for the FERC E-5 condition. It is possible, due to possible climate change that the past hydrology may not repeat. Future climate may be wetter, drier or distributed differently and in such a pattern that results in different water supply conditions. It would be necessary to develop criteria to evaluate different patterns of water supply for the purpose of estimating future impacts due to climate change. Those changes will probably be felt further in the future than the 20 year planning period covered by the City's UWMP update and any adverse impact to water supply should be lessened by reliance on groundwater pumping to meet increased demand In consideration of the uncertainties of climate, a detailed evaluation of multiple dry years with less than average runoff should be made of the future operations and possible impacts on the groundwater basin since the basin is a more reliable long term supply for drought insurance. Water level hydrographs in the Ukiah Valley that we have inspected do not show indications of long term or wide seasonal variation. Item C The City's water rights consist of groundwater (well #4), a State Water Board permit for 20 cfs, a contract with the Flood Control District for 800 acre feet per year and apre- 1949 right referenced in Decision D-1030 as 2.8cfs This right is based; in part, on a pre- 1914 appropriative right and may be larger than 2.8 cfs as D-1030 also references the City's maximum pumping at the that time to be 6.4 cfs. Cities generally have some latitude in the development of water rights over time, including pre-1914 water rights. Thus, the City's pre-1949 water right might be greater than 2.8 cfs.. Item D Ukiah's water right permit expired in 2000 and is currently subject to review by the State Water Board pursuant to a petition for time extension which was filed prior to expiration. The last time extension was approved in 1986. Subject to completing a CEQA document, in my opinion, based on my experience and other Water Board decisions, the time extension should be granted. Item E Reduced imports from the Bel River will cause lower lake levels in Lake Mendocino unless downstream demands are either curtailed or better managed. While the predicted lake level reductions are not the responsibility of Ukiah, lower than historic lake levels represent a significant impact to recreation. The development of the City's water right to its full potential will not cause adverse lake level declines (and the reduction or elimination of City's water right would not have a positive lake impact). However better management of lake releases could have a significant effect on predicted water levels in the future. SCWA has estimated that by timing irrigation diversions during dry periods it could preserve up to 20,000 acre feet per year in storage. Our analysis demonstrated that if the river could be managed to meet the minimum flow regime indicated in D-16] 0, the future result would be about 5 feet of additional water in storage at the end of September. An important factor that we could incorporate into the mode] is conservation in the form of targets tied to water supply conditions during the year. Item F Summary of criticisms/comments received thus far 1) Future extractions by the City will come from Project Water 2) River is fully appropriated and thus Ukiah can't expand into its 20 cfs water right 3) In dry years there will be no pre-1949 water, only project water 4) Need for Contract with Sonoma County Water Agency 5) The water will be extracted from a subterranean stream not a groundwater basin 6) Return flow should not be included in the analysis 7) Future inflow ignored PVID diversions Response to Item #1 The City's future water use, if expanded, will come from groundwater wells extracting water from the groundwater basin. The basin has been described by USGS (1985) as having up to 90,000 acre feet of storage. Groundwater levels indicate stability over time. There has been sufficient water available from direct recharge of precipitation, ungaged tributary inflow, inflow from the west fork, inflow from the East Fork in the winter months, to ensure a recharged groundwater basin. The City has not been reliant on Project Water to meets its water rights or it water supply needs. Project Water is restricted to water originating in the East Fork Russian River and diverted as either direct diversion or releases from storage to meet Flood Control District's contracts (8,000 acre foot Mendocino County reservation) downstream obligations (Sonoma County 10,000 acre foot reservation) Sonoma County Water Agency's instream flow obligations, and SCWA's water rights at Wohler. Project Water under the Flood Control District and SCWA's permit is restricted to the East Fork Russian River. Response to Item #2 Fully Appropriated streams declarations apply to applications to appropriate water pending at the time the stream or stream system is declared to be fully appropriated. Water Right Order 98-08, Order Revising Declaration of Fully Appropriated Streams by the State Water Resources Control Board states at paragraph 4.7, "No Provision of law provides that the Declaration is to affect existing water rights, regardless of their basis in legal doctrine. This would include rights in the process of being pertected, i.e., rights initiated under permits to appropriated un-appropriated water." Paragraph 7.0 of the Order states, "Nothing in this order shall be interpreted as affecting, or intending to affect, existing rights, regardless of their basis in legal doctrine." The City's permit was approved by D-1030 of the State Water Rights Board August 17, 1961 prior to the Fully Appropriated Stream listing (FAS) of the Russian River main stem in the summer months. The FAS listing imposes no constraint on the City's using up to the maximum 20 cfs allowed by its permit. Response to Item #3 Some have contended that in dry years, there is only Project Water available for diversion and that riparian, pre-1949 diverters and entities such as the City will not be able to exercise their water rights because they will be diverting water to which they have no right. We are not aware of any hydrological studies or basis to support that contention. The exceedance curves show the percent of years that water is available from inflow to Lake Mendocino and from gauged and ungauged tributary inflow for the summer months, for Ukiah (2.8 cfs), Mendocino County (8100 acre feet less the acre foot equivalent of 2.8 cfs), and for Sonoma County (20,000 acre feet). The analysis excludes Project Water. The amounts are based on the amount of pre-1949 water indicated in D-1030. The State Water Board recognized that occasionally pre-1949 diverters may benefit from project water but indicated that such occurrences would be rare. The analysis of water available for pre- 1949 diversions confirms the State Water Board's analysis (letter dated October 9, 1997 from Division Chief Edward C. Anton to Sonoma County Water Agency). Response to Item #4 Sonoma County Water Agency indicated that future diversions will come from Project Water and that Ukiah doesn't have a contract with SCWA. The future Ukiah extractions under its water right permit will come from The Ukiah Valley groundwater basin. SCWA's permit 12947A is limited to water originating in the East Fork Russian River. SCWA did not make it clear why it considers the future extractions by the City to be project water. The City's water right permit authorizes diversions from Russian River Undertlow, Jan 1 to December 31 without a bypass condition. It isn't necessary for Ukiah to enter into a contract with SCWA to extract wafer from the groundwater basin (or the subterranean stream). Response to Item #5 Ukiah's permit authorizes diversions from Russian River Undertlow, or what would be considered groundwater flowing in a subterranean stream within known and defined bed and banks. For prudent planning, our analysis assumes (without the City waiving any right to prove otherwise) that future extractions would be counted against the City's water right permit as pumping from a subterranean stream. Response to Item #6 The unused portion of any diversion is return flow. Almost every use of water including irrigation, and municipal and industrial use returns a portion of the diversion to the original source or to a different source or alternate use. The City's waste water treatment plant discharges water to percolation ponds that return water to the groundwater basin. At the point of discharge, the groundwater basin may be disconnected from the river but the treated water will return to the hydrological system to be re-used by the City, or others downstream. Response to Item #7 SCWA indicated that our analysis of inflow to Lake Mendocino under the FERC E-5 condition understates the future reduction in imports because we did not account for diversions by PVID. The data we used in our evaluation takes into account the diversions made by PVID. Mendocino County Russian River Flood Control & Water Conservation Improvement District 151 Laws Avenue, Suite D Ukiah, CA 95482 Phone (707) 462-5278 FAX (707) 462-5279 October 15, 2007 Members, City Council City of Ukiah 300 Seminary Ukiah, CA 95482 Re: 2007 Draft Urban Water Management Plan Dear Council Members: Thank you for allowing the Mendocino County Russian River Flood Control and Water Conservation Improvement District the opportunity to comment on the Draft Urban Water Management Plan for the City of iJkiah. Brown and Caldwell evidently subcontracted to Wagner &Bonsignore to prepare a report on the "Effect of Reduced Eel River Imports on Future Water Supply for City of Ukiah Urban Water Management Plan." This fatally flawed report, in the opening paragraph, states the water supply available for the City, as well as increased diversions, will have only minor effects on Lake Mendocino operations. This statement is not true and materially misrepresents the nature, extent, and substance of the water rights and the water rights holders who have the water rights in the reservoir. Any and all references by the consultant to the effects of increased diversions on the water supplies in Lake Mendocino are misplaced, erroneous, and become moot since the City of Ukiah has no water sunply in Lake Mendocino. The only two agencies that have any water supply in Lake Mendocino are the Sonoma County Water Agency (SCWA) and the Mendocino County Russian River Flood Control and Water Conservation Improvement District (MCRRFCD). Since this is the mistaken basis of Wagner & Bonsignore's entire report, we feel the necessity to point out that the entire report is inaccurate and flawed and, therefore, not admissible in the City's Urban Water Management Plan. Wagner &Bonsignore has looked at Lake Mendocino and has not evaluated the Russian River (including downstream users) who would be directly, and adversely, affected by additional diversions by the City unless the City initiated a major retrofit and conservation program to mitigate its increased diversions prior to the commencement of the new diversions. City Council City of Ukiah October 15, 2007 Page 2 One example of this inaccuracy is Wagner & Bonsignore's statement that the "...since the City does not take water out of the lake directly it does not directly affect water levels or storage." This emphasizes the consultants' failure to understand the nature and priority of the existing senior water rights and senior water rights holders on the river. Further, they are evidently not aware of the water supply functions of Lake Mendocino. As more water is diverted from the main channel of the Russian River, it becomes necessary to release water from Lake Mendocino (storage) to meet the mandatory downstream flow demands of the senior diverters and the mandated fish flow requirements for endangered anadromous fish. The basis of right of this released water belongs to either the MCRRFCD, or SCWA, or downstream appropriators with water rights that may have an earlier (senior) priority date than the City of Ukiah, or the fisheries under the public trust doctrine of the State of California. Obviously, the City of Ukiah's diversion would have a direct and adverse effect on water levels or storage, and additional municipal diversions from the river would require release of water from storage. This stored water would, of course, be water belonging to the Russian River Flood Control District, or the SCWA, and not to the City of Ukiah. It is unfortunate that the consultants missed this point since this proposal has the potential to adversely affect the water supplies of virtually every major agricultural enterprise and every domestic/urban water retailer in the Ukiah Valley. We believe that your consultants and staff must disclose the detailed truth to your Council regarding these grave issues before you are asked to make a decision. In an attempt to simplify the water system, there are three types of water in the Russian River that are available for diversion, rediversion, and/or appropriation. These types of water are natural flow, imported water, and project water belonging to MCRRFCD and SCWA. This water has different water classifications, namely Riparian, which carries the highest priority; Pre 1949; 1949 or District water; and Post 1949. (See attached Exhibit "A" for further description.) To give you an idea of how much water was available at the point of diversion of the City of Ukiah, attached is a spreadsheet (Exhibit "B") showing water availability from April through June of this year. It must be remembered, however, that this amount of water, along with accretion from tributaries (which is natural flow) also supplies all downstream users and streamflow requirements. The source of the data on this spreadsheet is the U.S. Army Corps of Engineers' monthly report (Exhibit "C"). Another area of disagreement is the reference to return flows to the Russian River. There are no return flows to the Russian River in the summer months. Wagner & Bonsignore estimate that approximately 15% of outdoor water use in the summer returns to the river system. This estimate is, we believe, inaccurate and overly inflated. As you know, pursuant to your permits, there can be no releases from the City's wastewater ponds in the summer and if there is a 15% City Council City of Ukiah October 15, 2007 Page 3 rate of percolation, the City is probably in violation of its Wastewater Permit, especially, if you include intrusion and infiltration. Also, any rancher along the Russian River will tell you that there is no return flow during the summer. The assertion of "return flows" that the city may rely on lacks any evidentiary support. The above points explain why we feel the Mr. Wagner's report is fatally flawed, inappropriate for inclusion in your Plan, and inaccurate. In order to accurately prepare an Urban Water Management Plan, which is a tool for planning, the study areas that must be fully evaluated, addressed, and mitigated for should be the Russian River, not Lake Mendocino. Sincerely, Barbara Spazek Executive Director /bs encl. EXHIBIT "A" MENDOCINO COUNTY RUSSIAN RIVER FLOOD CONTROL & WATER CONSERVATION IMPROVEMENT DISTRICT I. WATER CLASSIFICATION A. NATURAL FLOW Runoff originating within the watersheds tributary to the East Branch, West Branch and Main Stem of the Russian River. This flow would be proportional to the hydrographic area of each watershed. The amount of flow would be dependent on the rainfall and runoff characteristics of the rainfall season and would vary from substantial flows in the winter to minimal flows in the summer. The total natural flow within the Mendocino County Russian River Flood Control and Water Conservation District (District) could be quantified as five times the West Branch gage reading since the tributary area above the gage near Cummiskey Creek near the downstream boundary of the District is five times that above the West Branch gage. The West Branch gage can be used to calculate natural flows since it is not affected by Eel River water importations or Lake Mendocino releases. GAGES (a) West Branch - "Russian River Near Ukiah" Gage #4610 -Tributary Area - 100 square miles (b) East Branch Below Lake Mendocino - "Russian River East Fork Near Ukiah" Gage #4620 -Tributary Area - 105 square miles (c) East Branch Above Lake Mendocino - "East Fork Russian River Near Calpella" Gage #4615 -Tributary Area - 93 square miles (d) Cummiskey Creek - "Russian River Near Cloverdale" Gage #4630 -Tributary Area - 502 square miles B. IMPORTED FLOW The total amount of imported Eel River water net to Che District can be calculated as the flow entering Lake Mendocino less a natural tlow equal to the West Branch flow. Subtracting the West Branch flow quantity is reasonable since the East and West Branch tributary areas are approximately the same. This flow would be net to the District since it is measured below the Potter Valley diversions. C. PROJECT WATER Project Water is the amount of water in the Russian River that is present due to the operation of the Coyote Valley Dam/Lake Mendocino Project. The Project Water quantity can be calculated by subtracting the amount of Lake Mendocino inflow from the release flows. A negative number would indicate water being diverted to storage with no Project Water present in the Main Stem of the Russian River below the Dam. D. CALCULATIONS N = Natural Flow I = Imported Flow P = Project Flow "a" - "d" = Location of Gages AT FORKS N = 2 x "a" I = .~c„ _ «a„ AT CUMMISKEY CREEK N = 5 x "a" The above calculations would be unimpaired flows and would not reflect the amount of water diverted between these calculation points. II. WATER DIVERSIONS A. RIPARIAN The Riparian diversions would be diversions made to lands abutting upon the Russian River under the conditions for riparian usage. Only Natural Flow would be available for Riparian diversions. The Riparian diversions would be senior to appropriative diversions. B. 1949 APPROPRIATIVE In 1949, the State Department of Finance filed an application to appropriate the water generated by the construction and operation of the Coyote Valley Dam/Lake Mendocino Project. This application and permit was subsequently assigned to the Sonoma County Water Agency (SCWA) and the Mendocino County Russian River Flood Control and Water -2- Conservation Improvement District (District). The amount of water under the original permit has been allocated to the SCWA (27,544 AF), District (8000 AF) and individual diverters in Sonoma County (10,000 AF). The District's permit is subject to certain fishery streamflow requirements which may, in part, be satisfied by project water. District water may be put to beneficial use by individuals who redivert District water at defined locations along the Russian River. The District accounts for this rediverted water under its permit. C. PRE ]949APPROPRIATIVE When the 1949 permit was issued, it was estimated that approximately 8100 acre feet of water was being utilized within the District. The source of this water was natural Russian River water and imported Eel River water. The 1949 permit was subject to the rights of these Pre-1949 diverters. During and after construction of the project, there was a concerted effort to have the Pre- 1949 diverters submit water rights applications to the State to formalize their usage. The District records the usage amount and locations of these points of diversions. At certain times, there may be insufficient natural and imported water available to satisfy the Pre-1949 usage. During these periods, Pre-1949 deficiency would consist of project water and would be accounted for under the District's permit. D. POST 1949 APPROPRIATIVE Applications for new diversions after 1949 are for non-project water which is available during certain times of the year. The location and amount of each Post-1949 diversion is recorded by the District. During periods when "Post-1949" water is unavailable, water taken at these locations is considered re-diverted project water and is reported under the District's permits. E. STREAMFLOW As a condition of the 1949 Russian River permits, a fishery streamflow regime is required. This streamflow varies by time of year, water availability and location along the River. At certain times of the year, the streamflow may in part be made up from project water III. WATER USE ACCOUNTING Water use accounting within the District is accomplished by recording the amount pumped from each point of diversion (or re-rediversion) and classifying the diversion as Riparian, Pre-1949 Appropriative, 1949 Appropriative (District), or Post 1949 Appropriative. This classification will depend on the location of the diversion, the permit held by the diverter and the availability of water for that permit. All individuals and municipalities who have water agreements with the Russian River Flood Control District have meters on their pumps as required by said agreement. -3- Apri12007 Available For West Fork Riparian of cfs of Riparian 2312 \ 4624 East Fork Riparian 2312 / Potter Valley (Imported) 3464 8088 Riparian Available 4624 2331.42 Ripartian Used -3000 -1512.60 Escess Natural Flow 1624 818.82 Potter Valley (Imported) ~ 3464 1746.55 Available for Pre 1949 5088 2565.37 Only excess Natural Flow is available for Post 1949 May 2007 West Fork of cfs of Riparian 1090 2180 East Fork Riparian 1090 I Potter Valley (Imported) 5394 7574 of cfs Riparian Available 2180 1099.16 Ripartian Used -3000 -1512.60 Escess Natural Flow -820 -413.44 Potter Valley (Imported) 5394 2719.65 Available for Pre 1949 4574 2306.21 Only excess Natural Flow is available for Post 1949 June 2007 West Fork of cfs of Riparian 253.03 \ \ 506.06 East Fork ~ Riparian 253.03 / Potter Valley (Imported) 6244.97 6751.03 of cfs Riparian Available 506.06 255.16 Ripartian Used -3000 -1512.60 Escess Natural Flow -2493.94 -1257.44 Potter Valley (Imported) 6244.97 3148.71 Available for Pre 1949 3751.03 1891.27 Only excess Natural Flow is available for Post 1949 nussian nrver riooo convm uisma Comments on City of Ukiah U WMP ¢ U ~ < o - ~ E 5y w A Jzh w J 00 a -° o U q w ~ 0 0 0 0 0 0 0 0.0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 E a 3 0 i rc ~ ~ 3 °° 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 m mmm m ~, o o ~ %~ ' ~` o << ~ ~ ~ ~ m Q f rc" Q U ~ a `m J _~ Z y U ~ a Z - m m m m m w m w m m m m m m m m m m b m. m mmm m m m m mm m q K E W 'Y r r r r r r ~ r r r ~ r r n r r rr r r r r n ~ ~ ~ ~ n r c 7 d ~ z n m v u~ m r ` .- n. aV e~ N N n r rv n m m N Q c ~ ? tt O O O H F r LL _ V `~ m m m m m m m m m m m m m m m m m m m m m m m m m o> m m m 3 N_ m m ~ m m m mmm m n n n n rv n rv rv N N n n rv iv iv nn n n ITEM NO: 9b DATE: October 17. 2007 AGENDA SUMMARY REPORT SUBJECT: INTRODUCTION OF TWO ORDINANCES AMENDING PORTIONS OF DIVISION 3, CHAPTERS 1 AND 2 OF THE UKIAH CITY CODE AND DIVISION 6, CHAPTER 3, ARTICLES 1 AND 2, PERTAINING TO THE ADOPTION OF THE BUILDING CODES AND THE SAFETY/FIRE CODE AND AMENDMENTS THEREOF. SUMMARY: The purpose of this Agenda item is to introduce two ordinances that would make amendments to the City Code provisions related to Building and Fire regulations. The amendments are prompted by changes at the State level that will be occurring on January 1, 2008. The proposed amendments to Division 3, Chapters 1 and 2 (Building) and Division 6 Chapter 3 (Safety/Fire) concern the adoption of the California Code of Regulations (Title 24) with appendices, amendments, repeals, and one International Model Code. The proposed amendments are summarized below along with background information. (continued on page 2) RECOMMENDED ACTIONS: 1) Introduce by title only the ordinance amending to portions of Division 3, Chapters 1 and 2 of the Ukiah City Code pertaining to Building; and 2) Introduce by title only the ordinance amending Division 6, Chapter 3, Articles 1 and 2 of the Ukiah City Code pertaining to Safety/Fire. ALTERNATIVE COUNCIL POLICY OPTION: Do not introduce ordinances and provide direction to Staff. Citizen Advised: Advertized and held Public Workshop and noticed meeting in Ukiah Daily Journal. Requested by: David Willoughby, Building Inspector and Chuck Yates, Fire Marshal Prepared by: David Willoughby, Building Inspector and Chuck Yates, Fire Marshal Coordinated with: Candace Horsley, City Manager, David Rapport, CityAttomey, Charley Stump, Director of Planning and Community Development and Tony Clarabut, Fire Chief Attachments: 1. Ordinance for Adoption for Building Codes 2. Ordinance for Adoption for Safety/Fire Code 3. Bold and Strike-out Illustrated Version of Ordinance for Building Codes 4. Bold and Strike-Out Illustrated Version of Ordinance for Fire Code APPROVED: Can ace Horsley, City Mana ier Proaosed Amendments to Division 3. Chanter 1 and 21Buildina) The following list is a summary of the primary proposed changes: 1. References to various codes have been changed to reflect the Codes being adopted by the State, as well as for the Intemational Code being adopted. 2. In the Modifications to the Building Code section, the term "Demolition" was defined and an amendment to the Building Code concerning expired permits was added. 3. Exemption of political bodies from permit fees was repealed. This was requested by the participants at the public workshop. 4. In the Unreinforced Masonry Building section, the Existing Building Code was added as a standard intended to improve retrofitting these structures and the signage requirements were changed to reflect the current State requirements. Proaosed Amendments to Division 6. Chaater 31Safety/Fire) The Ukiah Fire Department and the Ukiah Valley Fire District have jointly worked on these modifications to make them common where overlapping issues exist for both agencies (i.e. fire sprinklers). 1. Much of the prior codes have been eliminated due to redundancy with the new Fire Code. Examples are duplicate definitions, requirements forflammable and combustible operations, and the uses of motor fuel and fuel fired appliances. 2. Requirements for sprinklers have been clarified. Previously they used a 1974 computation to figure fire flow. This recommendation proposed that Table B105.1 (appendix B of the CFC) be used to determine the fire flow for particular buildings, according to their type and size. It provides consistency and ease of application for the building community. This was one of the requests from the citizens at the ordinance review. BACKGROUND: Development in the methods and materials in the building industry and the degree of public safety required has constantly changed over the years. Because of this, the codes regulating buildings have also changed. In orderto speed up the code changing process, Califomia and other states have implemented a triennial review, modification, and adoption process. On January 1, 2008 California will adopt the new Title 24 Code of Regulations which includes the Administrative, Building, Electrical, Mechanical, Plumbing, Energy, Elevator Safety, Historical Building, Fire, Existing Building and the Referenced Standards Code. Califomia Building Standards (Title 24 Code of Regulations) are applicable to all occupancies throughout California, whether or not the local government takes an affirmative action to adopt those California Building Standards. By locally adopting an ordinance pertaining to Building and Fire Codes the City of Ukiah is: 1) Affirming the California Building Standards, 2) Able to add appendices and amendments to these Standards and 3) Able to add an additional Intemational Model Code. Aoaendices: Adopting the appendices allows the City to include important regulations including the Administrative portion of the Building and Fire Code as well as other pertinent regulations not contained in the body of the various codes. An example of this is the appendix on Signs. 2 Amendments to Standards: Adopting amendments to the California Building Standards allows the City of Ukiah to establish more restrictive standards which are reasonably necessary because of local climatic, geological, ortopographicalcnnditions. An example ofthis includes the requirement for a fire sprinkler system in certain cases for existing buildings. Intemational Model Code: Adopting the additional Intemational Model Codes allows the City to include information and regulations not contained in the California Building Standards. For example, the Intemational Property Maintenance Code which regulates the minimum requirements and standards for safety, maintenance, and the administration, enforcement and penalties associated with them. Once an ordinance is adopted locally, it must be filed with the California Building Standards Commission before the changes to the Codes become effective. ENVIRONMENTAL (CEQA) DETERMINATION: Staff has determined that the code amendment project is exempt from the requirements of the California Environmental Quality Act, pursuant to Section 15061(b)(3) because based on the information contained in the record, it can be seen with certainty that there is no possibility that the code amendments would cause a significant effect on the environment. RECOMMENDATION: 1) Introduce by title only the ordinance amending to portions of Division 3, Chapters 1 and 2 of the Ukiah City Code pertaining to Building; and 2) Introduce by title only the ordinance amending Division 6, Chapter 3, Articles 1 and 2 of the Ukiah City Code pertaining to Safety/Fire. 3 Attachment # ORDINANCE NO.

The section of the California Building Code, relating to applications for building permits is modified to require in an application to demolish a building, the date when the building was first constructed, if known. The terms "demolish" or "demolition," as used in this section, shall mean (1) the tearing down of all or part of a building or (2) the cumulative alteration of a building pursuant to one or more building permits issued over a five year period, where 50% or more of the structural or exterior components of the building are removed or replaced. The review required by this section shall occur with the application for the permit that (1) results in the tearing down of all or part of the building or (2) authorizes the cumulative alteration of the building that equals or exceeds the specified percentage. B. The section of the California Building Code, relating to the issuance of a building permit, is modified to require that, as to buildings constructed fifty (50) years or more prior to the date of application, the Director of Planning or his/her designee shall determine whether: 1. The building is an accessory building such as, but not limited to, a garage, storage shed, or carport, whether attached or detached to a main building; except that certain accessory buildings, such as carriage houses, which are presumed to have historic or architectural significance shall be subject to further review as provided in subsection D of this Section, unless the building is subject to demolition under subsection 62 of this Section. 2. Immediate demolition of the building is necessary to protect the public health or safety and the failure to immediately demolish the building would constitute a serious threat to the public health or safety. C. If subsection B1 or 62 of this Section applies to the building, no further review shall be required under this Section and the permit shall be issued in accordance with the provisions of the California Building Code. D. if the Planning Director finds that neither of the exceptions in subsection 61 or B2 of this Section applies to the building, a building permit to demolish a building shall be subject to further review in accordance with this Section. The Planning Director shall transmit the proposal to the Demolition Review Committee, or other official reviewing body established by the City Council, for review, comment, and a recommendation to the City Council. Once the Demolition Review Committee formulates a recommendation concerning the disposition of the proposed permit, the Planning Director shall schedule and duly notice the matter for a public hearing and decision by the City Council. The public i-s noticing shall indicate the day, time, place, and purpose of the public hearing, and how additional information about the subject matter can be obtained. The public noticing shall be accomplished in the following manner: 1. Publication in a newspaper of general circulation in the City at least ten (10) days prior to the hearing. 2. Mailing or delivery at least ten (10) days prior to the hearing to the owner(s) of the subject property, or his/her agent, and to the project applicant, if the applicant is not the owner. 3. First class mail notice to all owners (as shown on the latest available Mendocino County Tax Assessor's equalized assessment roll) of property within three hundred feet (300') of the subject property. E. In reviewing proposed permits, and formulating recommendations to the City Council, the Demolition Review Committee shall consider any information provided during the meeting, and shall use the following criteria. The structure: 1. Has a special or particular quality such as oldest, best example, largest, or last surviving example of its kind; or 2. Exemplifies or reflects special elements of the City's cultural, social, economic, political, aesthetic, or architectural history; or 3. Is strongly identified with persons or events significant in local, State, or national history. F. If the Demolition Review Committee finds that any of the criteria listed in subsection E of this Section apply to the building proposed for demolition, it shall recommend denial of the permit to the City. G. 1. The City Council shall conduct a public hearing pursuant to subsection D of this Section to consider the recommendation of the Demolition Review Committee, and to determine if any of the criteria listed in subsection E of this Section applies to the building proposed for demolition. If the City Council determines that any one of the criteria applies, it shall make a corresponding finding to that effect. ~-~ 2. At the hearing, the applicant shall have the opportunity to present evidence that a viable market does not exist for the building, taking into account the condition of the building, the probable cost to put the building into marketable condition, and the uses of the property allowed under existing or probable future zoning regulations. The City Council shall consider such evidence offered by the applicant and any other information presented at the meeting by any interested party or by staff, to determine whether or not a viable market exists. "Viable market" means that it is reasonably likely that the building could be sold within a commercially reasonable period of time for more than the seller would be required to invest in the purchase of the property and preparing the property for sale, or that the property could produce a reasonable return on the amount of money it would take to purchase the property and prepare the building for income producing purposes. "Reasonable return" means the average rate of return on real estate investments in the Ukiah Valley. 3. If the City Council determines that a viable market exists: a. It shat{ so notify the Building Official who shall not issue the permit. The City Council shall determine whether a viable market exists based on substantial evidence presented at the hearing, or, it may assume that a viable market exists, if the applicant fails to present substantial evidence that a viable market does not exist; b. Not more than once within any twelve (12) month period, the applicant may submit a new application for a permit and the City Council may reconsider whether a viable market exists: (1) Upon a showing by the applicant that market conditions have changed; or (2) Based upon new information that in the exercise of reasonable diligence the applicant could not have produced at the first hearing. 4. If the City Council determines, based on substantial evidence, that a viable market does not exist, the issuance of the permit shall be stayed for a period of ninety (90) days. a. During that ninety (90) day period, the City shall do the following: (1) Determine whether other alternatives to demolition exist, which are acceptable to the applicant, that would preserve the historic, architectural or cultural significance of the building; _~ (2) Determine whether funds are available from any private source for the acquisition and preservation of the building through a negotiated purchase on terms acceptable to the applicant; or (3) If sufficient funds are available from any private source and a negotiated purchase is not possible, determine whether to acquire the building through eminent domain. b. If within the ninety (90) days, the City does not reach agreement with the applicant or commence acquisition of the building, the Building Official may issue the permit in accordance with the provisions of the California Building Code. c. If within the ninety (90) day period, the City either: 1) reaches agreement with the applicant or 2) commences acquisition of the building, the Building Official shall not issue the permit. d. However, the Building Official shall continue to process the application for the permit in accordance with the California Building Code, if the City and the applicant terminate their agreement or the City fails to diligently pursue or abandons acquisition of the building. e. The City Manager or his/her designee shall inform the Building Official whenever the City and the applicant terminate their agreement or the City fails to diligently pursue or abandons acquisition of the building. f. If the Building Official has issued a permit under this subsection and the permittee applies to extend the permit an additional one hundred eighty (180) days in accordance with the applicable provisions of the California Building Code then in effect, the Building Official shall refer the application to the City Manager for an initial determination as to whether market conditions have changed. The City Manager shall make the determination within ten (10) days after the application is referred by the Building Official. If the City Manager determines that market conditions may have changed and that a viable market may exist for the property, he or she shall schedule the matter for a hearing before the City Council to be noticed and conducted in accordance with subsections D and G of this Section. However, at the hearing the City shall have the burden of proving by a preponderance of the evidence that market conditions have changed and a viable market exists. If the City Manager determines that market conditions have not changed, he or she shall so notify the Building Official and the applicant. Upon such notification, the Building Official shall further process the application to extend the term of the permit in accordance with the requirements of the ~ ~~ California Building Code then in effect. If the City Council conducts a hearing upon referral by the City Manager, the City Clerk shall provide written notification to the Building Official and the applicant of the City Council decision. If the City Council decides that a viable market exists, the Building Official shall not issue the permit, but the provisions of subsection Gab of this Section shall apply. If the City Council decides that a viable market does not exist, the Building Official immediately shall proceed to further process the application in accordance with the applicable provisions of the California Building Code then in effect. 5. "Diligently pursue acquisition" means taking all steps within the time required by law to acquire the building by eminent domain. 6. References to "applicant" herein shall include the building owner. H. The Planning Director shall provide a written notice of the City Council determination to the applicant. The written notification shall be mailed or hand delivered within five (5) days from the date of the City Council's decision.

The building is an accessory building such as, but not limited to, a garage, storage shed, or carport, whether attached or detached to a main building; except that certain accessory buildings, such as carriage houses, which are presumed to have historic or architectural significance shall be subject to further review as provided in subsection D of this Section, unless the building is subject to demolition under subsection B2 of this Section. 2. Immediate demolition of the building is necessary to protect the public health or safety and the failure to immediately demolish the building would constitute a serious threat to the public health or safety. C. If subsection B1 or B2 of this Section applies to the building, no further review shall be required under this Section and the permit shall be issued in accordance with the provisions of the 13a+#ere} California Building Code. D. If the Planning Director finds that neither of the exceptions in subsection B1 or 62 of this Section applies to the building, a building t#ae-deaaelit~e+~ permit to demolish a building shall be subject to further review in accordance with this Section. The Planning Director shall transmit the proposal to the Demolition Rerreit Review Committee, or other official reviewing body established by the City Council, for review, comment, and a recommendation to the City Council. Once the Demolition Remit Review Committee formulates a recommendation concerning the disposition of the proposed dea~elitiea permit, the Planning Director shall schedule and duly notice the matter for a public hearing and decision by the City Council. The public noticing shall indicate the day, time, place, and purpose of the public hearing, and how additional information about the subject matter can be obtained. The public noticing shall be accomplished in the following manner: 1. Publication in a newspaper of general circulation in the City at least ten (10) days prior to the hearing. 2. Mailing or delivery at least ten (10) days prior to the hearing to the owner(s) of the subject property, or his/her agent, and to the project applicant, if the applicant is not the owner. 3. First class mail notice to all owners (as shown on the latest available Mendocino County Tax Assessor's equalized assessment roll) of property within three hundred feet (300') of the subject property. E. In reviewing proposed deaaelitiea permits, and formulating recommendations to the City Council, the Demolition Rerrait Review Committee shall consider any information provided during the meeting, and shall use the following criteria. The structure: 5 3 -- ~ 1. Has a special or particular quality such as oldest, best example, largest, or last surviving example of its kind; or 2. Exemplifies or reflects special elements of the City's cultural, social, economic, political, aesthetic, or architectural history; or 3. Is strongly identified with persons or events significant in local, State, or national history. F. If the Demolition tt Review Committee finds that any of the criteria listed in subsection E of this Section apply to the building proposed for demolition, it shall recommend denial of the deaae4itiea permit to the City. G. 1. The City Council shall conduct a public hearing pursuant to subsection D of this Section to consider the recommendation of the Demolition Refrait Review Committee, and to determine if any of the criteria listed in subsection E of this Section apply to the building proposed for demolition. If the City Council determines that any one of the criteria apply applies, it shall make a corresponding finding to that effect. 2. At the hearing, the applicant shall have the opportunity to present evidence that a viable market does not exist for the building, taking into account the condition of the building, the probable cost to put the building into marketable condition, and the uses of the property allowed under existing or probable future zoning regulations. The City Council shall consider such evidence offered by the applicant and any other information presented at the meeting by any interested party or by staff, to determine whether or not a viable market exists. "Viable market" means that it is reasonably likely that the building could be sold within a commercially reasonable period of time for more than the seller would be required to invest in the purchase of the property and preparing the property for sale, or that the property could produce a reasonable return on the amount of money it would take to purchase the property and prepare the building for income producing purposes. "Reasonable return" means the average rate of return on real estate investments in the Ukiah Valley. 3. If the City Council determines that a viable market exists: a. It shall so notify the Building Official who shall not issue the deraelitiea permit. The City Council shall determine whether a viable market exists based on substantial evidence presented at the hearing, or, it may assume that a viable market exists, if the applicant fails to present substantial evidence that a viable market does not exist; b. Not more than once within any twelve (12) month period, the applicant may submit a new application for a deaaelitier~ permit and the City Council may reconsider whether a viable market exists: (1) Upon a showing by the applicant that market conditions have changed; or (2) Based upon new information that in the exercise of reasonable diligence the applicant could not have produced at the first hearing. 3~~ 4. If the City Council determines, based on substantial evidence, that a viable market does not exist, the issuance of the der~eiitier~ permit shall be stayed for a period of ninety (90) days. a. During that ninety (90) day period, the City shall do the following: (1) Determine whether other alternatives to demolition exist, which are acceptable to the applicant, that would preserve the historic, architectural or cultural significance of the building; (2) Determine whether funds are available from any private source for the acquisition and preservation of the building through a negotiated purchase on terms acceptable to the applicant; or (3) If sufficient funds are available from any private source and a negotiated purchase is not possible, determine whether to acquire the building through eminent domain. b. If within the ninety (90) days, the City does not reach agreement with the applicant or commence acquisition of the building, the Building Official may issue the permit in accordance with the provisions of the lifer-rrt California Building Code. c. If within the ninety (90) day period, the City either: 1) reaches agreement with the applicant or 2) commences acquisition of the building, the Building Official shall not issue the deaaeiitiea permit. d. However, the Building Official shall continue to process the application for a deaael+tiee the permit in accordance with the 13ai#eF~ California Building Code, if the City and the applicant terminate their agreement or the City fails to diligently pursue or abandons acquisition of the building. e. The City Manager or his/her designee shall inform the Building Official whenever the City and the applicant terminate their agreement or the City fails to diligently pursue or abandons acquisition of the building. f. If the Building Official has issued a dereeiitiea permit under this subsection and the permittee applies to extend the permit an additional one hundred eighty (180) days in accordance with the applicable provisions of the li#erm California Building Code then in effect, the Building Official shall refer the application to the City Manager for an initial determination as to whether market conditions have changed. The City Manager shall make the determination within ten (10) days after the application is referred by the Building Official. If the City Manager determines that market conditions may have changed and that a viable market may exist for the property, he or she shall schedule the matter for a hearing before the City Council to be noticed and conducted in accordance with subsections D and G of this Section. However, at the hearing the City shall have the burden of proving by a preponderance of the evidence that market conditions have changed and a viable market exists. If the City Manager determines that market conditions have not changed, he or she shall so notify the Building Official and the applicant. Upon such notification, the Building Official shall further process the application to extend the term of the deaaeiitiea permit in accordance 3- ~ with the requirements of the t3ai#errr~ California Building Code then in effect. If the City Council conducts a hearing upon referral by the City Manager, the City Clerk shall provide written notification to the Building Official and the applicant of the City Council decision. If the City Council decides that a viable market exists, the Building Official shall not issue the permit, but the provisions of subsection Gab of this Section shall apply. If the City Council decides that a viable market does not exist, the Building Official immediately shall proceed to further process the application in accordance with the applicable provisions of the >Ja+fe~ California Building Code then in effect. 5. "Diligently pursue acquisition" means taking all steps within the time required by law to acquire the building by eminent domain. 6. References to "applicant" herein shall include the building owner. H. The Planning Director shall provide a written notice of the City Council determination to the applicant. The written notification shall be mailed or hand delivered within five (5) days from the date of the City Council's decision. The notice shall include the finding(s) and decision made by the City Council and a copy of this Section. I. The applicant for a deraelitiea permit for a building determined to have historic, architectural or cultural significance shall salvage the building materials for reuse to the maximum extent feasible, and shall ensure that upon completion of the demolition, the site is left in a safe, presentable, and clutter free condition. J. Reconsideration aof Decisions: 1. Grounds For Reconsideration: The City Council may reconsider a decision under this Section within sixty (60) calendar days from the date the decision was made, if information that may have materially affected the decision was: a) misrepresented by the applicant, or b) not disclosed by the applicant, if the applicant knew or should have known that the information may have affected the City Council decision. "Information" as used herein means matters of fact or law. A decision may not be reconsidered, if all three (3) of the following have occurred. The derwe4+tien permit: a) has been issued, b) did not at the time it was issued violate any provision of the f3ni#errr~ California Building Code, as adopted by the City, or any other City ordinance or State or Federal law, and c) the permittee has commenced demolition in good faith reliance on the permit. 2. Procedure On Reconsideration: Reconsideration of a decision under this Section may be placed on the agenda for a regular City Council meeting by any member of the City Council who voted in favor of the original decision. Notice of any meeting where reconsideration is on the agenda shall be provided in accordance with subsection D of this Section. If already issued, the permit shall be suspended from the date that an eligible City Council member requests that the matter be placed on the agenda and until the City Council makes a final decision upon reconsideration.

Introduced by title only on , 2007, by the following roll call vote: AYES: NOES: ~, ABSENT: ABSTAIN: Adopted on , 2007 by the following roll call vote: AYES: NOES: ABSENT: ABSTAIN: Mari Rodin, Mayor ATTEST: Linda Brown, City Clerk ITEM NO: l0a MEETING DATE: October 17, 2007 AGENDA SUMMARY REPORT SUBJECT: FURTHER DISCUSSION AND POSSIBLE ACTION REGARDING PETITION TO CHANGE PLACE OF USE AND POINTS OF DIVERSION IN RESPONSE TO LETTERS FROM WILLOW AND MILLVIEW COUNTY WATER DISTRICTS SUMMARY: The City Council recently decided to revise the petition it has filed with the State Water Resources Control Board ("Water Board") to change the place of use and points of diversion under the City's appropriative water rights permit. The Council decided to exchange points of diversion with Millview County Water District ("Millview") and Willow County Water District ("Willow") to address the emergency intertie issue. It also decided to add to the City's place of use the area encompassed by the sphere of influence as discussed with Mendocino County in connection with a tax sharing agreement. A draft map prepared by Wagner and Bonsignore, showing these proposed changes, is attached as Attachment 1. A map prepared by the City's Public Works Department (Attachment 2) shows the differences between the sphere of influence as described in the City's 1995 General Plan and the Sphere of Influence (SOI) recently discussed with Mendocino County. On September 14, 2007, the City received a letter from the General Manager of Willow, saying that Willow is opposed to the City changing its place of use to include the Willow County Water District service area. (A copy of the letter is Attachment 3 to this report.) In a subsequent phone call with Willow's General Manager, the City Manager learned Continued on oaae 2 RECOMMENDED ACTION: Discuss and provide staff with direction. ALTERNATIVE COUNCIL POLICY OPTIONS: N/A Citizens Advised: N/A Requested by: City Council Prepared by: David J. Rapport, City Attorney Coordinated with: Candace Horsley, City Manager, Wagner and Bonsignore, Attachments: Attachment 1-Draft Amended Map to Accompany Change Petition Attachment 2 -Public Works Map Attachment 3- Letter from Willow County Water District Attachment 4- Letter from Millview County Water District Approved: Candace Horsley, Cit Manager Agenda Summary Report Page 2 June 20, 2007, City Council meeting that Willow would not agree to exchange points of diversion, if the City sought to include Willow's service area in the City's place of use. In objecting to the City's change petition, the General Manager relied on a map depicting the sphere of influence area within Willow's service area. He indicated to the City Manager that most of Willow's customers are located within that area. The City has received a similar letter from Mlllview's General Manager (Attachment 4). However, in a recent conservation with Millview's General Manager, the City Manager learned that Millview will still exchange points of diversion to address the emergency intertie issue. Staff is bringing these recent developments to the City Council for direction on how to proceed. The following are among the City Council's options: 1. It could proceed with the petition to change the place of use as approved by the City Council and continue to exchange points of diversion with Millview. This would address future annexations and the emergency interie between Millview and the City. Under this option, the City would have to rely on Urgency Change Petitions to exchange water with Willow through the emergency interie, and Willow and Millview would presumably oppose the petition to the extent it included any of their service areas. 2. It could pursue exchanging points of diversion with Willow and not seek to change its place of use to include any areas currently (1) served by Willow or (2) within the current boundaries of Willow. This could involve negotiating an agreement with Willow to address water service in the event of future City annexations in that area. Millview may continue to oppose the petition to the extent it includes Millview's service area. The City could pursue similar negotiations with Millview. It may be that either or both districts would not oppose a petition to change the City's place of use to include their service areas, if the City agreed that in any annexation, the districts could continue to serve their existing connections. 3. It could proceed with place of use as currently described in the petition on file with the Water Board, which includes all of Millview and Willow in the City's place of use, and seek to include the condition previously discussed with the Council that would limit the use of the interties to emergencies only.

At Willow's last regular Board Meeting the Board of Directors went on record stating that they do not support any action by the City of Ukiah that includes expanding the City of Ukiah's Place of Use into any portion of Willow's service area, and will vigorously protest any application by Ukiah to the State Water Resources Control Board to do so. The City's action is all the more frustrating because there is no rational support for the action other than the City's desire to pursue development within the boundaries of Willow County Water District. The City's June 20, 2007 Agenda Summary Repoli acknowledges that: "Both Millview and Willow prefer solution to the intertie problem that involve the least amount of changes to the physical environment and which, therefore, minimize the environmental review under the California Environmental Quality Act." Nevertheless, the City has taken the most aggressive action, including in its proposed place of use areas that it may want to annex in the future, which will require a CEQA evaluation of the growth inducing impacts of furnishing City water to those areas. The City's action is not required by its desire to implement the existing Emergency [ntertie Agreement among Ukiah, Willow and Millview. Implementation of this agreement can be accomplished at the time of an emergency through a Petition for "A California Special District" An efficient and responsive form of local government. Temporary Urgency Action. This is the more conservative alternative Willow has decided to pursue. If the City wants assurances ahead of time that it will be able to use water immediately, the issue can be addressed by simply adding Willow's wells to the City's authorized points of diversion under its permit. Exchanging points of diversion has no growth inducing effects because it does not make any more water available to the agencies involved. The City's action goes beyond that, however, and includes area that it wishes to annex in the future in its petition to change its place of use. These proposed azeas include Willow, and significant lands to the south and west of Willow. The proposed amendment to the City's place of use is premature. Before any annexation can take place the City must obtain the approval of the Mendocino County LAFCO. LAFCO is the appropriate entity to determine which governmental agencies can provide services in the most efficient way to the people and property in any given azea. At this point the lands proposed to be added to the City's place of use are not even within the City's sphere of influence. Once again, LAFCO makes the determination of the appropriate sphere of influence, not the City, and this has not yet been accomplished. LAFCO's determination of the appropriate sphere of influence for a public agency works to discourage urban sprawl by preventing overlapping jurisdictions and duplications of services. We would urge the City to follow the appropriate order of things and refrain from including lands within its proposed place of use that aze currently within the boundaries of other public agencies, because LAFCO has not yet made a determination that these lands aze appropriately included within the City's sphere of influence.

The original intent of expanding the azea of use was to provide water under the emergency inter-tie agreements. The expanded area of use the city council has approved only includes areas within both Districts that aze already densely populated or zoned for future development. At the Districts March 28, 2007 Board of Directors meeting, the decision to file amended water right petitions that limited the place of use to the existing District boundaries and the former lands of Masonite was made. The District presented a letter (see attached) to the City Manager informing her of this decision and presented an alternative to minimize the environmental review process. It appears the City is more interested in contemplating future annexation of select azeas within the boundaries of the Millview and Willow Water Districts. There is no viable reason to expand the City's area of use to include any portion of the Millview District.

ITEM NO: 10b MEETING DATE: October 17, 2007 AGENDA SUMMARY REPORT SUBJECT: DISCUSSION AND POSSIBLE APPROVAL OF R.W. BECK RECOMMENDATIONS FOR GOBBI SUBSTATION CAPACITY UPGRADE AND HYDRO EXPRESS FEEDER (PHASE II) IN THE AMOUNT OF $490,287; AUTHORIZE CITY MANAGER TO NEGOTIATE CONTRACT; AUTHORIZE BUDGET AMENDMENT FOR SAME. Background: On December 20, 2006 the City Council approved the award of a consulting contract to R.W. Beck (Beck) for Phase I -Study of Alternatives and Design for Gobbi Substation (Gobbi) in the amount of $53,300. The Phase II portion of Beck's proposal was not awarded due to the need to complete the initial Phase I assessment in order to provide an accurate budget for engineering services based on the specific needs for the City of Ukiah. An estimate of $253,055 for the Phase II portion was provided as a reference amount based on the work Beck expected to perform for a very similar project in the City of Healdsburg. Beck completed Phase I and presented options to the City Council on September 19, 2007. At that meeting the City Council directed Beck to develop the Phase II engineering proposal for immediate, short term and long term needs; including the addition of a third transformer at Gobbi, System Control and Data Acquisition (SCADA) and an express feeder from Gobbi to the Lake Mendocino Hydroelectric Power Plant. Continued on Paae 2 RECOMMENDATION: Discussion and possible approval of R.W. Beck recommendations for Gobbi Substation Capacity Upgrade and Hydro Express Feeder (Phase II) as outlined in attached proposal (Attachment 1) in the amount of $490,287; Authorize City Manager to negotiate contract; Authorize budget amendment for same.

Beck Phase II Proposal - to be delivered 2 -October 3, 2007 Agenda Summary Report which includes December 20, 2006 Agenda Summary Report and proposal. Approved: ../`t/`~~~~_~~~ ,~ Candace Horsley, City Manager At the October 3, 2007 City Council Meeting Beck presented a proposal for Phase II - Implementation of the System Improvements for the City of Ukiah in the amount of $490,287. The proposal included engineering services for project management, preliminary engineering, detailed engineering, construction contract procurement, major equipment procurement, engineering during construction, SCADA implementation, and distribution line design. In order to make a comparative analysis the City Council directed Beck to provide a more detailed list itemizing the costs associated with the tasks for the initial preliminary $253,055 estimate and the $490,287 proposal generated after completion of the Phase I work in order to make a comparative analysis. Subsequent Action: On October 8, 2007 a conference call with Councilmembers Crane and McCowen, staff and Beck was held to discuss the City Council's request of October 3rd. The parties came to an understanding that the initial Phase II proposal was intended as a 'ballpark' figure based solely on a similar project at Healdsburg, rather than being derived from actual engineering services specific to the City of Ukiah. Beck also provided an overall project estimate of $5M to include their Phase II engineering services and construction costs, with an understanding that this figure is based on the proposal outlined at the October 3, 2007 City Council Meeting. After the Preliminary Engineering has been completed, Beck will provide an updated report to the City Council. In addition, Councilmembers requested a detailed breakdown of the proposed charges which included proprietary information. As such, the consultants are currently preparing a revised version of the information requested which will be delivered prior to the Council meeting on October 17, 2007. Staff recommends approving Beck's Phase II recommendations for Gobbi Substation Capacity Upgrade and Hydro Express Feeder in order to expedite the necessary improvements required to maintain reliable electric service for the city's electric customers. Staff further recommends the City Manager be authorized to negotiate a contract for same and approve budget amendment transferring $490,287 from Electric Fund 800 Fund Balance to 800.3642.800.000.

Recent equipment failures and a lengthy outage at Gobbi Substation support the need to proceed with the consulting evaluation and redesign/construction of the Gobbi Substation to ensure Ukiah continued reliable electric service and to provide additional capacity to accommodate increasing electric loads. Interim repairs have been completed; however, the substation is in need of a number of upgrades for long term reliability. _ Continued on Gage 2 RECOMMENDED ACTION: Approve award of consulting contract to R. W. Beck in the amount of $53,300 for the initial assessment portion of the work. ALTERNATIVE COUNCIL OPTIONS: Select an alternate consultant or reject all bids. FUNDING: Amount Budgeted $300,000 Account Number Additional Funds Requested 800.3642.250.000 NA Citizens Advised: NA Requested by: Jeff Gould, interim Public Utilities Director Prepared by: Jeff Gould, Interim Public Utilities Director Coordinated with: Candace Horsley, City Manager Attachments 1 -Gobbi Substation Consultant Comparison Approved: Candace Horsley, City Manager Staff developed a Request for Proposal (RFP) and solicited proposals from 12 consultants, and received 4 responses. The RFP required the consultants to perform the work in two phases: Phase I: Initial Evaluation of Gobbi Substation condition and investigation of alternatives for increasing the total substation capacity for Ukiah. A. Consultants will review the Gobbi Substation equipment condition, configuration of the substation connections and make recommendations for improvements to Gobbi Substation. B. As part of the initial consulting effort staff required the consultant to consider three alternatives for increasing Ukiah's substation capacity: 1. Replace the two existing Gobbi Substation transformers with larger units; 2. Addition of a third transformer at Gobbi Substation (and associated reconfiguration of the Gobbi Substation); and, 3. Evaluate the costs and benefits of developing a new (additional) substation at a separate location (further north in Ukiah) to provide increased capacity and a new transmission delivery point. This approach, while more expensive, would enhance Ukiah's system reliability by providing a backup to the Gobbi Substation in the event of another substation outage. Once the Phase I work effort is completed the consultant will submit a report with recommendations and make a presentation to City Council. Council will be requested to provide guidance on the options for the substation capacity upgrade. Phase II: Design of the Gobbi Substation upgrades and SCADA svstem The consultant would proceed with design of the recommended/approved upgrades for Gobbi Substation. Depending upon which capacity upgrade option is selected; the Gobbi Substation upgrade may include replacement addition of transformer capacity. However, if Council elects Option #3 (the new substation), the upgrades at Gobbi Substation would not include increasing transformer capacity. The design of the new substation (Option #3) is not part of this contract and is not funded in the current budget. A separate consulting contract RFP process would be developed if the new substation option is approved by Council. The new RFP would include procurement of a new substation site, transmission connection arrangements, and design of the new substation. Consulting Costs The cost of the Phase I consultant work (initial evaluation and capacity options) is $53,300. The Phase II design and project management costs are estimated to be an additional $253,000; however, the actual Phase II cost will have to be determined once the capacity alternatives decision is made (upon completion of the Phase I report). Staff will bring back the Phase II scope of work for Council approval after the completion of Phase I. Staff believes it is important to have the design work performed by the same firm that completes the assessment to insure continuity of the information and cost control. Staff is requesting that Council approve the Phase I (initial evaluation) contract in the amount of $53,300. Staff reviewed the four proposals considering similar experience, approach to the project, compliance with the RFP, and cost of the Phase I work. Attachment #1 is a comparison evaluation of the four proposals. Staff recommends the contract be awarded to R. W. Beck. The R. W. Beck proposal complied with the RFP and provided all services including seismic design and oil containment considerations in their design work scope. The consultant has extensive experience with similar projects and their overall services include project management of the construction. While the other bidders had similar capabilities, the R. W. Beck proposal provided the best combination of scope, compliance with the RFP, and Phase I cost. I I I I ~; I EI I I L. '~ I UI A Q C ~ A E ~ I ~ r 1 y u r ~.

R.W. Beck Executive Summary 2. R.W. Seck Power Point Presentation Approved: Candace Horsley, City M ager Atluci invent # _~______ City of Ukiah Gobbi Substation Upgrade Study by R. W. Beck EXECUTIVE SUMMARY The City of Ukiah depends upon a single point of interconnection with Pacific Gas and Electric Company at Gobbi Substation for the delivery of electric power. The substation was constructed more than 20 years ago and is now operating at its maximum reliable capacity. In July 2006, the substation experienced a major malfunction which disrupted service to the entire City. The cause of the failure appears to have been a malfunctioning electric switch. To address concerns about the long term reliability of the substation, earlier this year, the Electric Department engaged the engineering firm R. W. Beck to perform a condition assessment of the Substation and to identify and evaluate alternatives to extend the useful life of the substation. R. W. Beck's initial condition assessment and report are complete. The report finds that the substation needs immediate, short term and long term improvements to ensure the reliable, safe and cost-effective supply of electricity to the City. Key findings of the R. W. Beck Study include: ^ The City's electrical demand has reached the maximum reliable capacity of the substation. Additional transformer capacity is needed at Gobbi Substation to ensure reliable service for increasing electric demand. ^ The substation does not comply with federal environmental requirements for oil spill containment. A Spill Prevention, Contro] and Countermeasures Plan and secondary oil containment for the power transformers. ^ The substation fence is closer to the high voltage electrical conductars than allowed by industry standards. The westerly fence should be relocated to maintain safe clearances. ^ The substation configuration of distribution circuit breakers limits the operating flexibility of the substation and inhibits the ability of electric crews to perform necessary maintenance. An additional 12-kV circuit breaker should be added to relieve this constraint. ^ The protection and control systems in the substation are showing signs of failure and should be replaced with a modern protection system to ensure reliable electric service. ^ The City's hydroelectric power generating station shares a 12-kV distribution feeder with customer loads which creates an operating constraint for the hydroelectric plant. A dedicated distribution feeder should be constructed to the hydroelectric plant to R. W. Beck ES-1 maximize the economic value of the plant and minimize the adverse operating conditions to electric customers and the substation. ^ If the City's electric demand increases to more than about 50-MW, the City should consider a second point of interconnection with PG&E and a second substation to serve City loads. A second substation as an alternative to increasing the capacity of the existing substation was considered. The cost and time to develop a second substation are not desirable alternatives when compared to the proposed recommendations. Evaluation of Alternatives R. W. Beck evaluated the following four options for increasing the capacity of Gobbi Substation: 1. Upgrade the existing power transformers to increase their capacity 2. Replace the existing power transformers with new, higher capacity power transformers 3. Add a third power transformer and metal-clad switchgear. 4. Construct a new substation, with a second point of interconnection to PG&E. The following table summarizes the key attributes of each of these options. Table E-1 Comparison of Capacity Expansion Alternatives and Design for Gobbi Substation Capacity Reliability Operation Estimated Increase/ Flexibility Cost Option #1- Upgrading Transformers 2 x 2-3 MVA Medium Low $90,000 Long- Lead Term Time Prospects 2-4 years 8 weeks Option #2- Replace 2 x 13 MVA Medium to Medium $3 Million 15 years 70 weeks Transformers High Option #3- Add a 1 x 37 MVA Medium Medium $1.9 Million 10 years 90 weeks Third Transformer Option #4- Add a 2 x 50 MVA High High $4 Millions 30 years 125 + New Substation weeks 1. Not Including Land Costs R. W. Beck ES-2 Option #I provides only a slight increase in capacity but has several associated technical uncertainties, and may not even be technically feasible. This alternative should be further considered as an operational mechanism to address the time to implement a longer term significant increase in load serving capability Option # 2 would solve the capacity issue, but has a higher cost than Option #3, which provides similar benefits. Further Option #2 does not provide the reliability advantage of Option #3 Option #4, while providing many benefits, has a significantly higher cost than the other options, and the implementation time could be substantially longer than any of the other options. Recommendations In order to provide adequate long-term reliability and capacity to serve load and extend the useful life of the substation, demand driven improvements are recommended which would: ^ Address immediate capacity and reliability concerns at Gobbi Substation by: ^ Increasing substation capacity by - splitting the load between both transformers, or - running Gobbi's two transformers in parallel during the summer peak load periods; ^ Preparing a Spill Prevention, Control and Countermeasure Plan meeting the requirements of CFR 40 112. ^ Moving the removable chain-link fence's west side one (1) foot closer to the street, to comply with ANSI C37.32-1946 Outdoor Electrical sub-station clearances; ^ Obtaining a spare 121-kV circuit switcher with disconnect switch; ^ Developing an effective operating and maintenance program for the substation; ^ Conducting a thermographic substation survey and repairing{correcting abnormalities, including rusted galvanized steel electrical connectors; ^ Installing a fifth feeder breaker and restoring the bus tie breaker to its original function; and ^ Perform preliminary engineering to confirm the feasibility of adding a third transformer and metal-clad switchgear; This work should commence as soon as possible in order to be completed before the 2008 peak load season.

TO APPROVE SALE, ASSIGNMENT OF WASTE COLLECTION AGREEMENT AND RESTRUCTURING OF COMPANIES BY BUYERS SUMMARY: The City received a request from Solid Waste Systems, Inc. ("SWS") to approve a sale of the company, an assignment of the waste collection contract and a restructuring of companies by the buyers to operate the Taylor Drive Transfer Station and to collect solid waste in the City. The City currently has two agreements with SWS: (1) A Transfer Station Agreement for the operation of the solid waste transfer station on Taylor Drive and (2) a Waste and Recyclables Collection Franchise Agreement ("Waste Collection Contract") for the collection of waste and recyclables within the City. North Bay Corporation, as the owner of the Taylor Drive property, is also a party to the Transfer Station Agreement Under both agreements, any change in ownership or control or assignment of the agreements requires the City Council's approval. SWS and North Bay Corporation are both owned by the Ratto Holding Company which is owned by Jim Ratto and his wife (collectively, "Ratto"). Ratto has entered agreements to sell companies it owns in Sonoma County, Lake County and Ukiah to David Carroll, John Shay and Bruce RECOMMENDED ACTION: Receive status report, discuss, provide direction to the subcommittee and schedule an adjourned regular or special meeting to consider a subcommittee recommendation on the request. ALTERNATIVE COUNCIL POLICY OPTIONS: N/A Requested by: Solid Waste Systems, Inc. Prepared by: David J. Rapport, City Attorney Coordinated with: Vice Mayor Doug Crane, Council member John McCowen, Candace Horsley, City Manager, Emmett Jones, Consultant, and Gordon Elton, Interim Finance Director Approved: Candace Horsley, ity Manager Agenda Summary Report October 17, 2007, City Council meeting Page 2 McCracken (collectively, "Buyers"). In Ukiah, Ratto and Buyers are seeking approval from the City Council for the following: 1. The sale of the stock in SWS to Buyers with the result that the Transfer Station will be operated by SWS, then to be owned by Buyer rather than Ratto. Since they are buying the stock and SWS will continue to operate the Transfer Station, this does not require an assignment of the Transfer Station agreement or any other agreements used by SWS to operate the Transfer Station. 2. An assignment of the Waste Collection Contract to a new corporation owned by Buyers. The new corporation is called Ukiah Waste Systems, Inc. ("UWS") with the result that UWS rather than the SWS collection division will perform waste collection in the City. 3. Transfer of the ownership of the Taylor Drive property from North Bay Corporation to a new limited liability company owned by Buyers called Yalupa Investments, LLC ("Yalupa"). 4. Most of the equipment now used to operate the Transfer Station and collect waste in the City and additional equipment to be owned by a new corporation called Mendocino leasing Company and leased to the other entities owned by Buyers. 5. Permission under the Transfer Station agreement to take green waste and wood waste to a facility on North State Street operated by a company owned by Buyers called Pacific Recycling Solutions, Inc. ("PRS"). 6. Permission under the Waste Collection Contract to take single stream recyclables directly to PRS at the North State Street location rather than to the Transfer Station, once the North State Street operation is fully permitted and equipped to operate a materials recovery facility ("MRF"). The Buyers' proposed business plan involves some significant changes to the current arrangement for collecting and disposing of solid waste in the City, Currently, all waste and recyclables are taken to the Transfer Station. From there, green waste and wood waste is trucked to Cold Creek Composting in Potter Valley for processing. Single stream recyclables are trucked from the Transfer Station to a MRF in Sonoma County operated by a Ratto company called Timber Cove Recycling. Under the Buyers' business plan, green waste and wood waste would be collected in the City and taken directly to PRS at the North State Street facility for grinding. That green and wood waste grinding facility is already fully permitted and operating. Once PRS is operating a MRF at North State Street, single stream recycling would be collected in the City and taken directly to the North State facility for processing. Separated and bailed recyclables would be sold directly into the market by the PRS. To respond to these requests, the City formed a subcommittee composed of Vice Mayor Crane and Council member McCowen to conduct a due diligence review and make a Agenda Summary Report Page 3 October 17, 2007, City Council meeting recommendation to the City Council. An outside consultant, Emmett Jones, Gordon Elton and the City Attorney have acted as staff and advisers to the subcommittee. Under a confidentiality agreement, the subcommittee has obtained from the Buyers all of the transaction documents involved in this sale and considerable financial information about the proposed new companies. Based on a review of this material, the subcommittee has requested and received additional information and there have been several written exchanges between the attorney representing the Buyers and the City Attorney to address concerns raised by the subcommittee. This process is on-going. Through their attorney, the Buyers have indicated that the bank which is providing a "credit facility" to finance these transactions has notified the Buyers that the current purchase agreements must close by the end of October or the bank's loan commitment will expire. The Buyers have received approval for the sale from the jurisdictions in Lake County. If they don't have the City's approval by the end of the month, they will have to exclude Ukiah and close on the purchase of the other companies. At a minimum, this will complicate the financing of the Ukiah transaction, increasing the costs to the Buyer. The due diligence review began at the end of July and has taken longer than the Buyers and their bank originally anticipated. Staff recommends that the City Council attempt to make a decision within this time frame, if that can be done without adversely affecting the City's legitimate interests. For that reason, the subcommittee will ask the Council to consider calling an adjourned regular or special meeting for later in October to allow additional time for the subcommittee to finalize its due diligence review and to formulate a recommendation to the City Council. The subcommittee has conducted its review with the following principles in mind: 1. The City should have the same contractual rights and protections under this new arrangement as it has under the existing one; 2. The new companies and SWS should have adequate resources and a viable business plan to successfully pertorm for the full term of the Transfer Station and Waste Collection Contracts; 3. The rates for waste collection should not increase, because of new costs arising from the purchase of these businesses. In other words, the rate base should not include costs which would not exist, but for the sale of the companies to the Buyers; and 4. Any significant deficiencies in the existing contracts should be revised as a condition of approving the sale. These principles have guided the subcommittee in requesting additional information and in proposing conditions on the City's approval of the sale. It is possible, but not likely, that the outstanding issues raised by the subcommittee will Agenda Summary Report October 17, 2007, City Council meeting Page 4 be resolved in time to make a recommendation to the City Council for consideration at the October 17 meeting. The subcommittee and staff will present any additional information at the City Council meeting and prior to any adjourned regular or special meeting that may be called by the City Council. ITEM NO: > oa DATE: October 17, 2007 AGENDA SUMMARY REPORT SUBJECT: STATUS REPORT, DISCUSSION AND DIRECTION CONCERNING THE HISTORIC RANCH HOUSE STRUCTURE LOCATED AT 1325 AIRPORT PARK BOULEVARD SUMMARY: On June 6, 2007, the City Council adopted a Mitigated Negative Declaration and approved a Building Permit to demolish (relocate) the old Dutton Ranch house located at 1325 Airport Park Boulevard to the Kushner property at 504 North Oak Street. The Kushner's have decided not to pursue relocating the ranch house, and the property owner has revised the required plan for preserving the structure. The purpose of this Agenda Item is to provide a status report of the project and to receive Council direction. BACKGROUND: On May 2, 2007, the City Council made the determination that the original ranch house structure located at 1325 Airport Park Boulevard was historically significant and pursuant to the Ukiah City Code, stayed the issuance of the proposed Building Permit to demolish the house for up to ninety days to allow time for possible preservation. The Council also directed Staff to prepare the required Initial Environmental Study and determine if a Mitigated Negative Declaration or Environmental Impact Report should be prepared for the project. (continued on page 2) RECOMMENDED ACTION: 1) Find the revised Preservation Plan consistent with the require mitigation measure contained in the adopted Mitigated Negative Declaration; and 2) Approve the Building Permit to disassemble and relocate the structure to 270 Kunzler Ranch Road. ALTERNATIVE COUNCIL POLICY OPTION: Provide alternative direction to Staff. Citizen Advised: Gary Ackerstrom Requested by: Property owner FYHRCO, Inc.

RECOMMENDED ACTION: 1) Receive Status Report; and 2) Review and provide direction regarding the review and c N E .c a Q Attachment # v STRUCTURE PRESERVATION PLAN The purpose of this Plan is to outline a proposal to preserve the historical portion of the structure located at 1325 Airport Park Boulevazd,Ukiah,California(AP#180-110-10). The remainingportion ofthe structure, which was used as a residence by the Dutton/Langley family, consists of atwo-story section having a ground footprint of approximately 400 SF. The structure could be saved by relocation to a different site since it is not economical to restore the structure at its current location. Also, moving the structure as a single, intact unit is not feasible due to its height. This Plan involves the disassembling of the structure and storing the components at North Counties Development Corporation Yazd located at 270 Kunzler Ranch Road, Ukiah, CA, until a different site can be found for later reconstruction. The plan for this work would be as follows: 1. Make a visual record of the structure at its current location by means of photographs. 2. Remove and store the undeteriorated doors, windows, trim, posts, and siding from the structure. 3. Remove and dispose of deteriorated items such as roofing, interior wall sheeting, wall covering, wiring and plumbing systems. 4. Remove and save the roof and floor structural components. Remove the walls in sections for later reassembling. Remove and dispose of the foundation. By utilizing the above outlined procedure, this structure could be reassembled as an addition to a structure having essentially the same architectural appearance. Obviously deteriorated or substandazd structural components would have to be disposed, reconfigured or replaced for safety purposes. Also, as a new structure, provisions would have to be made for modern electrical, plumbing, HVAC, fire safety, foundation, and insulation systems. The anticipated time frame for this work would be to disassemble the structure within a month and reassemble the structure within a year after the permit is issued. toiaio~ Attachment ~' 3 Redwood Business Park (FYHRCO) Proposed Demolition -1886 Ranch House 1325 Airport Park Blvd., APN 180-110-10 1 ITEM NO: loe DATE: October 17, 2007 AGENDA SUMMARY REPORT SUBJECT: RECEIVE STATUS REPORT CONCERNING CODE COMPLIANCE ACTIVITIES SUMMARY: This Agenda Item is intended to provide the Council with a brief status report concerning recent code enforcement activities.

FOR TEST HOLE DRILLING TO EVALUATE POTENTIAL AQUIFER FOR MUNICIPAL WELLS AT A COMPENSATION OF $30,600.00 AND AUTHORIZE STAFF TO NEGIOTIATE A CHANGE ORDER FOR THE PUMPING CAPACITY AND WATER SAMPLE ANALYSIS NOT TO EXCEED A FUNDING LEVEL OF $10,000 The bidder's two deviations from the project specifications pertained to two optional items: 1. Sieve analysis, catalog, shipping and report, and 2. Pumping capacity and water sample for analysis. Obviously, the purpose of the test hole drilling is to determine if there is an aquifer of sufficient quantity and quality to support the placement of municipal wells at two defined areas. Of all the optional work services, the pumping capacity and water sample analysis is extremely important. The Bidder qualified this optional work task to include the disposal of any extracted water from the wells onto the respective drill sites, the air lifting of the water sample by the Contractor, and providing the City a best guess estimate of the flow currently produced under a snap shot test of 2 minute duration time. Multiple tests and water samples would be taken and submitted to the City for water analysis at the City's expense. The cost for the qualified option is $500.00 per well. The RFB, under Scope of Work Item No. 16, requires the Contractor to conduct a preliminary pumping capacity test for each aquifer encountered sufficient to provide an estimate of developed pumping capacity. It requires that water samples be collected from each aquifer encountered in accordance with proper water quality sampling procedures to prevent contamination and ensure the integrity of the samples. The Contractor shall submit the samples to the City for analysis. Staff has included in this agenda summary report a recommendation to authorize staff to negotiate a change order for both well sites to perform the pumping tests as qualified by the bidder at a funding level not to exceed $1,000. The recommended award at $30,600 would cover the following scope of work items: • Drill Test Hole at $50 per foot up to 200 ft for each well site at potential total cost of $20,000.00 • Mobilization, demobilization, final cleanup, temporary shutdown ,filling of test hole, and incompletion of test hole at $8,600 for well site 1 and $2,000 for well site 2 for total of $10,600 irrespective of the actual location of the site. The first well site is the first site chosen for drilling. The optional work tasks and associated costs are as follows: • Collection of drill cutting samples at $1,000 per well site • Sieve analysis of drill cutting samples at 500 per well as was qualified to exclude a State certified Soils Lab. • Geophysical logging at $3,000 per well site • Pumping capacity and water samples at $500 per well as qualified and described above • Well log at $500 per well site • Daily drillers report at $500 per well site With winter weather approaching, the City Council is advised that any further delay in this matter may result in the work being performed in the spring of next year.
