EXHIBIT A
CITY OF UKIAH RECYCLED WATER SYSTEM:
PHASES 3& 4 WATER BALANCE, ZERO DISCHARGE, AND ALTERNATIVES ANALYSES;
AND PHASE 3 DESIGN
SCOPE OF WORK
February 25, 2016
BACKGROUND
The City of Ukiah (OWNER) has requested that Carollo Engineers, Inc. (ENGINEER) develop a
scope and budget for preparation of a water balance and zero discharge report, and a
refinements analysis technical memorandum for the Phase 3 and Phase 4 Recycled Water
System Project. The City wishes to determine if it is more cost effective to increase recycled
water usage and storage or to make changes to its wastewater treatment plant (WWTP) to
potentially allow increases in effluent discharges to the Russian River and its percolation ponds.
OWNER has also requested that ENGINEER develop a scope and budget to prepare the design of
the Phase 3 recycled water pipeline from its connection to the Phase 2 pipeline, currently under
final design, to a termination point adjacent to the eastern side of Highway 101 at the City's
Little League park / water treatment plant site. The ENGINEER will also include changing the
Phases 1 and 2 3- million gallons (MG) recycled water storage pond design to a combined Phases
1, 2 and 3 72 -MG pond on City -owned land directly south of and adjacent to the City's WWTP.
Carollo recently completed the Preliminary Design Report for the associated Phases 1 and 2
project, and final design is underway. With a completed State Revolving Funds (SRF) application,
the City wishes to proceed with Phases 1- 3 and eventually 4. Phase 4 is planned with a
separate SRF loan application due to the currently undefined storage volume and location
(possibly zero discharge). Phases 1 through 4 are generally defined in the Recycled Water
Feasibility Study, Carollo, December 2012. The Phases have been refined as the project(s) move
forward into design efforts.
A water balance and zero discharge study is initially needed for two purposes: 1) to ensure that
the finalized Phases 3 and 4 project is fully integrated with the Phases 1 and 2 project; and 2) to
see if zero discharge can reasonably be achieved instead of nitrogen removal from the WWTP
discharge to the river. The Phases 1 and 2 project is being designed assuming Phases 3 and 4 will
be built. The integration relates primarily to the amount of recycled water storage, and the
associated pumping facilities, to be provided. Preparing this study at this time also allows any
minor changes to Phases 1 and 2 to be included in that project's bid documents. In addition,
there are other considerations that need to be analyzed prior to finalizing the Phase 3 project
and the selected project for Phase 4, including:
• Potential future revisions to the City's WWTP NPDES discharge permit and the Basin
1
Plan that could impact or remove the use of percolation ponds and / or direct discharge
to the Russian River. This could lead to a zero discharge regulatory requirement. The
City also wants to determine if zero discharge is economically viable even if it does not
become a legal requirement.
• Flow and treatment constraints at the WWTP, including the Advanced Water Treatment
(AWT) facility and particularly the chlorine contact basins. A review is needed to
determine what the most cost - effective solution is balancing any WWTP improvements
against the amount of recycled water storage to be provided.
• Constraints on recycled water production imposed by low raw wastewater inflows to
the WWTP at certain times of the year.
• Recent increases in demand for recycled water for agricultural and landscaping use, and
the potential for more use on City -owned land. This considers both irrigation and frost
protection.
• Availability and future use of existing storage facilities, including privately -owned ponds
and possible conversion of the WWTP sludge lagoon and some or all of the WWTP
percolation ponds to recycled water storage.
• Possible provision and the location of additional storage facilities at the end of the
Phase 4 pipeline.
• Potential for extension of the recycled water system, including possible storage, further
south from the current end of the Phase 1 and 2 pipeline.
Work under this scope is organized under seven Tasks as follows:
Phases 3 and 4 - Water Balance and Zero Discharge Report
• Task 1 - Project Management
• Task 2 - Water Balance and Zero Discharge Analysis
• Task 3 - Phases 3 and 4 Refinement
Phase 3 Permitting and Design
• Task 4 - Phase 3 Survey, Geotechnical Investigation, Utilities, Easement Requirements
& Environmental
• Task 5 - Phase 3 Final Design
• Task 6 - Phase 3 Permitting
• Task 7 - Phase 3 Right -of -Way Acquisition Assistance
The following design phase tasks for Phase 3 are already included within the work being carried
out for the Phases 1 and 2 final design:
• Project management for Tasks 4 -7;
• SRF funding assistance;
• CDPH Engineer's Report revision;
• Bid phase services.
At the completion of Task 3, the water balance assessment will have been completed, the
viability of zero discharge solutions addressed, and a series of project refinements evaluated
2
and recommended. Tasks 4 through 7 will run concurrently with Tasks 1 through 3 as the City
wishes to include the Phase 3 project with Phases 1 and 2, currently in final design, in a single
Phases 1, 2 and 3 bid package. The results of Task 3 will be included as agreed upon within the
Phase 3 final design. It is envisioned that preliminary and final design of the selected Phase 4
project will be carried out under a subsequent scope and budget following City approval.
Carollo will continue to lead the planning and engineering effort for Phases 1 -3 of the recycled
water project, with SMB Environmental providing input on environmental factors impacting the
analyses and design. SMB will also prepare an Addendum to the Initial Study / Mitigated
Negative Declaration (IS / MND) to include the expanded Phases 1, 2 and 3 recycled water
storage pond. For the Phase 3 and subsequent Phase 4 project designs, local consultants LACO
Associates and Rau & Associates will provide similar field and engineering services to the Phases
1 and 2 project.
SCOPE OF WORK
TASK 1— PROJECT MANAGEMENT
Task 1 includes for project management for Tasks 2 and 3. Project management for Tasks 4
through 7 is included in the Phases 1 and 2 project.
Task 1.1- Project Administration
The ENGINEER will administer the project and subconsultants to maintain project schedule and
budget. The project progress and budget status will be included in monthly progress reportsthat will
be attached to billing invoices. Additionally, the monthly progress reportwill include a list of work
completed forthetime period and what is expected inthe coming period.
Task 1.2 - Meetings
The ENGINEER will coordinate project tasks between the OWNER, subconsultants, stakeholders
and other agencies as required through project meetings. The ENGINEER will prepare an agenda
and brief meeting summaries for each of the meetings. Anticipated project meetings are
identified below:
• Project Kick -off Meeting (OWNER offices)
• Monthly Project Status Meetings (Conference call) (Assume two (2) total)
• Draft Water Balance and Zero Discharge Report Review Meeting (OWNER offices)
• Stakeholder and Agency Meetings (Assume two (2) total - assumed to coincide with
other meetings under this project and under Phases 1 and 2 final design) (OWNER
offices and Sacramento or Walnut Creek). These could include the RWQCB, SWRCB, or
others.
• Phases 3 and 4 Refinements Brainstorming Workshop (OWNER offices)
• Draft Phases 3 and 4 Refinements Analysis Technical Memorandum Review Meeting
(OWNER offices)
3
Task 1.3 — Quality Control
Quality control will be monitored throughout the entirety of the Project. The ENGINEER will
review deliverables provided by subconsultants prior to forwarding to the OWNER'S staff. Any
document developed by the ENGINEER will be peer- reviewed internally prior to delivery to the
OWNER.
Task 1: Deliverables:
• Monthly status reports
• Meeting agendas and brief summaries
TASK 2 - WATER BALANCE AND ZERO DISCHARGE ANALYSIS
Task 2.1 - Data Collection and Review of Previous Water Balance Report
The ENGINEER will review relevant data and information provided by the OWNER, including the
previous water balance reporting contained in the City of Ukiah 2011 NPDES Permit Renewal
Plan of Disposal Report of December 2011; the Recycled Water Feasibility Study of 2012; and the
finalized Phases 1 and 2 Preliminary Design Report of December 2015. The ENGINEER will also
review WWTP influent and effluent flow and other operational data provided by the OWNER.
Task 2.2 - Review and Confirm Phases 1 - 4 Recycled Water Demands
The ENGINEER will review and update the recycled water demands for all four phases using data
extracted from previous reports, information previously provided by the OWNER, and recent
agreements between the OWNER and stakeholders to supply recycled water. These finalized
demands will be used in analyses to be carried out as part of later Tasks.
Task 2.3 - Review WWTP Constraints and Potential NPDES Permit Revisions
With the assistance of, and data and information provided by, the OWNER'S Engineering and
Maintenance and Operations staff, the ENGINEER will examine and review current and
anticipated constraints on the WWTP's ability to produce recycled water. This will include a
review of historical raw wastewater inflows, the hydraulic performance of the AWT and the
chlorine contact basins, effluent flows, available capacity of the percolation ponds over time,
percolation rates, and historical discharges to the Russian River.
Under this Task, the ENGINEER will also examine and review the potential impact on design of
the City's proposed recycled water system caused by potential future changes in the WWTP's
NPDES Discharge Permit and /or the Basin Plan. While not immediately envisioned under the
current permit renewal cycle, there could be significant impacts if the North Coast Regional
Water Quality Control Board was, for example, to prohibit the use of the percolation ponds
adjacent to the Russian River, or require zero discharge to the river. The potential for these
changes and the economic impact must be considered when determining the build -out storage
and pumping requirements of the Phases 3 and 4 recycled water system project. The results of
4
this review will be used in the analyses to be undertaken under subsequent Tasks.
Task 2.4 - Prepare Draft Water Balance and Zero Discharge Report
Using the data and information provided by the OWNER and the results of reviews and analyses
carried out under earlier Tasks, the ENGINEER will construct a water balance model in order to
define proposed recycled water storage and pumping requirements for all phases of the City's
Recycled Water System Project. Analysis using the model will address current and projected
future conditions and will be based upon available data from 2011 until the present. The
ENGINEER will also review the data and conclusions detailed in the City of Ukiah 2011 NPDES
Permit Renewal Plan of Disposal Report of December 2011, which covered the period from 2006
to 2010. Data will include WWTP inflows and effluent discharges, river flows, percolation pond
levels / available capacity, and current recycled water demand projections.
Findings and conclusions will be presented in a draft Water Balance and Zero Discharge Report.
In addition to the primary goal of defining storage and pumping requirements, the report will
also address the technical and economic viability of a zero discharge alternative. The results of
the water balance and zero discharge studies will be used as part of the Phases 3 and 4
refinements analyses to be carried out under Task 3.
The draft report will be submitted to the OWNER for review and subsequent discussion at a
workshop.
Task 2.5 - Draft Water Balance and Zero Discharge Report Workshop
A workshop will be held with the OWNER to consider the conclusions of the draft Report and to
address the OWNER'S review comments. Once comments for incorporation have been agreed,
the Report will be finalized.
Task 2.6 - Prepare Final Water Balance and Zero Discharge Report
The Water Balance and Zero Discharge Report will be finalized under this Task, incorporating the
OWNER'S agreed review comments.
Task2:Assumptions
• Water balance modeling of current conditions will use data from the period 2011 to the
present, and results will be compared to the historical water balance modeling results
and conclusions presented in the 2011 Basis of Disposal Report; the data used in the
Change in Point of Use permit, and to the design flows presented in the Phases 1 and 2
Preliminary Design Report. Future conditions modeling will be based on flow projections
and on finalized recycled water demands.
• Recycled water demand projections current at the end of Task 2.2 will be used in Task 2
modeling and analyses. Any increases in demand due to further signed recycled water
agreements after the end of Task 2.2 will be considered during the Phases 3 and 4
design.

Task 2: Deliverables:
• Draft Water Balance and Zero Discharge Report (1 pdf copy)
• Final Water Balance and Zero Discharge Report (2 hard copies and 1 pdf)
• Comments log
• Workshop agenda and minutes
TASK 3 - PHASES 3 AND 4 REFINEMENT
Task 3.1 - Prepare Initial List of Phase 3 and Phase 4 Refinements
Using the recycled water demand projections and the storage and pumping facility
requirements defined in the final Water Balance and Zero Discharge Report prepared under
Task 2, the ENGINEER will prepare an initial list of potential refinements (up to 15) to the Phases
3 and 4 project. The list will include zero discharge options if these were found to be technically
and economically viable under previous Tasks. If zero discharge is not found cost - effective,
alternatives for expansion of the recycled water system that consider the cost of permit- driven
improvements to the WWTP will be developed. The refinements will consider various locations
for recycled water storage (on private and City -owned land), conversion of WWTP percolation
ponds to recycled water storage if found viable, intermediate pumping options, use of an
upstream reservoir at the head of Phase 4, and various pipeline routes, including across the river
to serve irrigated lands there. The ENGINEER will prepare descriptions and maps depicting the
refinements for use at a brainstorming workshop with the City to be undertaken under the
following Task.
Task 3.2 - Brainstorming Workshop
The OWNER and the ENGINEER will review the initial list of refinements to Phases 3 and 4
prepared under Task 3.1 at a brainstorming workshop. Other potential options will also be
considered. The intent is to agree at the workshop on a shortlist of up to 5 project refinements
for subsequent detailed evaluation. The brainstorming workshop will broadly consider any fatal
flaws to each refinement, relative construction and life cycle costs, ease of operation and
maintenance, flexibility for future modification and expansion, environmental considerations,
public impacts, possible impacts in the Russian River floodway, and requirements and costs for
right -of -way and land acquisition. Conclusions from the workshop and definition of the
shortlisted project refinements will be recorded in meeting minutes for future inclusion in the
Phases 3 and 4 Refinements Analysis Technical Memorandum (TM) to be prepared under a later
Task.
Task 3.3 - Detailed Evaluation of Shortlisted Phase 3 and Phase 4 Refinements
The ENGINEER will undertake a detailed evaluation of the (up to 5) shortlisted Phases 3 and 4
refinements defined at the Task 3.2 Brainstorming Workshop. This detailed evaluation will
include:
• Capital, operation, maintenance, power, and life cycle (net present value) costs.
6
• Right -of -way and / or land availability, and acquisition costs.
• Ease of operation and maintenance.
• Flexibility for expansion.
• Impacts on Phases 1 and 2.
• Environmental / visual and aesthetic impacts during and after construction.
• Public and stakeholder impacts during and after construction, including traffic and
impacts on agricultural operations.
A Triple Bottom Line (TBL) analysis model addressing the above financial, environmental, and
social factors will be used as part of the detailed evaluation. The model will allow these factors
to be weighted, so the sensitivity of the ranking of the refinements can be assessed. A summary
matrix will be developed that defines the above listed criteria.
Task 3.4 - Prepare Draft Phases 3 and 4 Refinements Analysis TM
Using the results of the detailed evaluation of the shortlisted project refinements and the TBL
modeling under the previous Task, the ENGINEER will prepare a draft Phases 3 and 4
Refinements Analysis TM. This TM will describe the identification of the initial list of
refinements, the process, and results of the brainstorming workshop to produce the shortlist of
Phases 3 and 4 refinements, and the detailed evaluation of that shortlist. The TM will present
findings and conclusions, and recommend modifications to the Phase 3 design and the preferred
Phase 4 project for subsequent preliminary and detailed design. The TM will also address
compatibility between the Phases 3 and 4 projects and the Phases 1 and 2 project under final
design, and define any proposed minor revisions to the Phases 1 and 2 project design for
discussion and agreement with the OWNER.
The draft TM will be submitted to the OWNER for review and subsequent discussion at a
workshop.
Task 3.5 - Draft Phases 3 and 4 Refinements Analysis TM Workshop
A workshop will be held with the OWNER to consider the conclusions of the draft TM and to
address the OWNER'S review comments. Once comments for incorporation have been agreed,
the TM will be finalized.
Task 3.6 - Prepare Final Phases 3 and 4 Refinements Analysis TM
The Phases 3 and 4 Refinements Analysis TM will be finalized under this Task, incorporating the
OWNER'S agreed review comments.
Tosk3: Assumptions:
• The initial list of Phases 3 and 4 project refinements will be limited to a maximum of 15,
and detailed evaluation of shortlisted refinements will be limited to 5.
• Analysis will be limited to a "desktop" evaluation. No fieldwork will be conducted as part
of this effort.

TASK 4 - PHASE 3 SURVEY, GEOTECHNICAL INVESTIGATION, UTILITIES, EASEMENT
REQUIREMENTS & ENVIRONMENTAL
Under Task 4, the ENGINEER will perform pre -final design activities for the Phase 3 pipeline and
the expanded Phases 1, 2 and 3 recycled water storage pond to the south of the WWTP. These
include topographic survey and mapping; geotechnical and corrosion investigation; existing
utilities research; identification of permit and easement requirements; and environmental
studies and preparation of an Addendum to the existing IS / MND. Deliverables prepared as part
of this task will be used for design in subsequent tasks.
Task 4.1- Topographical Survey and Mapping
The ENGINEER'S sub consultant Rau and Associates, Inc. (RAU) will establish project survey
control and prepare encroachment permit area and easement mapping for the Phase 3 project.
The work will be coordinated with RAU's previous work on the Phases 1 and 2 project. RAU will
set approximately 25 durable (1/2" iron pipes or reinforcement bars in undeveloped areas; PK
nails or pipes in pavement) horizontal and vertical control points for project mapping in
accordance with City of Ukiah horizontal and vertical control requirements. This will include
searching for, and locating, monuments from adjacent records of survey. These survey control
points will be exhibited on a "Survey Control Data Sheet" and will be semi - permanent in nature
so as to serve as project control during the construction of the project, or subsequent survey
activities.
Field measurements will be performed using GPS methods on the same horizontal basis as the
topographic mapping control survey. All surveying and mapping shall be in compliance with City
of Ukiah standards, or with Caltrans standards when not otherwise specified by the City.
The horizontal datum will be based on the North American Datum 83 (NAD 83). The vertical
datum shall be based on the North American Vertical Datum of 1988 (NAVD 88).
Pipeline Topographic Surveys
RAU will perform ground surveys using electronic total station methods to complete a
topographic survey of a strip, approximately 40 feet wide, over the length of the Phase 3
pipeline route. The topographic mapping will be done concurrently with boundary survey work,
using the control network described above, for efficiency.
Survey data will be processed and rendered into a Digital Terrain Model (DTM) and CAD base
map. The project base map will include:
8
• Terrain (1 foot contours).
• Sufficient pipeline project area length to verify proposed future alignment at ends.
• Existing utilities and structures present within the project mapping limits, or that may
affect the project because of their close proximity.
• Trees greater than 4" in diameter at breast height (dbh) that may be affected by the
project.
• Existing right -of -way lines within, or in close proximity to, the project limits.
• Project control.
• Height of overhead utility lines that may conflict with the project.
Detailed Topographic Surveys at the Recycled Water Pond, and Select Structures at the WWTP
RAU will perform ground surveys to supplement information provided by the City to detail the
outlets from the WWTP Chlorine Contact Basins (flume, overflow weir level), buried pipes, and
structures up to, and including, the outline of the Dechlorination Facility. An effort will be made
to establish the invert elevations of the buried outlets and piping between the Chlorine Contact
Basins and the Dechlorination Facility from construction plans, from interviews with plant
personnel, and from direct measurements where possible.
More detailed topographic mapping will be done between the sludge lagoon and Percolation
Pond #2, including the tops of embankments and slopes of embankments, parallel with the
recycled water pipeline route. The top of embankment and slope of the embankment, both
north and south of the south side of Percolation Pond #2 is also included in this more detailed
mapping. In addition to the surface profile of the embankment, the location of a fence along the
south side of the embankment and the detailed topography of a swale south of this
embankment which conveys storm water to the Russian River will be mapped.
Detailed topographic mapping out to the top of the bank of the Russian River will be conducted
to the east. Approximately 15 to 20 feet beyond the top of bank will be included to provide
some information as to the slope of the river bank in this area. To the west, there is already
detailed mapping across the North Coast Railroad Authority (NCRA) right -of -way (80'). The
supplemental mapping at Percolation Pond #2 will provide detailed topography north of the
proposed pond for a distance of 80 to 100 feet. To the south, the detailed topographic mapping
will extend approximately 100 feet beyond the proposed pond limits.
RAU will provide detailed topographic and facility mapping of selected WWTP features, a
recycled water pond site map and a DTM in AutoCAD Civil 3D format, that includes:
• Terrain (1 foot contours with spot elevations for tops of berms;
• Embankments between the Chlorine Contact Basin and Percolation Pond #2;
• Embankment along the south side of Percolation Pond #2;
• Drainage channel parallel and south of Percolation Pond #2;
• Bottom elevation of Percolation Pond #2 from record data (no surveys from boats).
• Bottom Elevations of Chlorine Contact Basins with side slope location and gradient adjacent
to the Dechlorination Facility;
• Outline of the Dechlorination Facility and elevations of critical inverts;
9
• Invert elevations of piping crossing the recycled water pipeline route;
• Sufficient channel length and detail to evaluate the hydraulics of the storm water drainage
conveyance channel south of Percolation Pond #2;
• Existing utilities and structures present within the project mapping area, or that may affect
the project because of their close proximity;
• Trees greater than 4" in dbh that may be affected by the project, and significant riparian
vegetation adjacent to the storm water drainage conveyance channel south of Percolation
Pond #2, and within 10 feet of top of the bank of the Russian River.
• Project control points;
• Ordinary High -Water Mark for the storm drainage conveyance channel only;
• Height of overhead utility lines that may conflict with the project.
Detailed Topographic Surveys at Watercourse Crossings
RAU will perform ground surveys using electronic total station methods to complete a detailed
topographic survey of up to 4 watercourse crossings, approximately 60 feet to 80 feet along the
thread of the watercourse or drainage ditch, and appropriately by 40 feet to 60 feet wide. This
mapping is to provide exhibit maps for permits where needed, and for directional boring
installations.
The detailed watercourse crossing topographic mapping will be done on the same basis as the
boundary survey work, using the control network described above. It will be done after the
permit requirements are defined so that all relevant information can be collected. Location of
visible utilities, trees over 4 inches in dbh, and significant riparian vegetation, within the detailed
mapping limits will be included in this task. The survey data will be processed and rendered into
a DTM and CAD base map.
RAU will provide a topographic watercourse site map and DTM in AutoCAD Civil 3D format that
includes:
• Terrain (1 foot contours);
• Thalweg (flowline) location and gradient;
• Sufficient channel length and detail to evaluate hydraulics;
• Existing utilities and structures present within the project mapping area, or that may
affect the project because of their close proximity;
• Trees greater than 4" in dbh that may be affected by the project and significant riparian
vegetation;
• Existing right -of -way lines if in close proximity;
• Project control;
• Ordinary High -Water Mark;
• Height of overhead utility lines that may conflict with the project.
Prepare and File Record of Survey Map — Babcock Lane Right -of -Way
In order to establish the right -of -way of Babcock Lane (aka River Road) during Phases 1 and 2
survey, RAU had to extend the boundary survey from near Talmage Road to Gobbi Street. There
was no definitive evidence along nearly 1,800 feet of Babcock Lane to establish the right -of -way.
10
There are no records of survey along this segment of River Road (as it was originally known)
since the original subdivision map prepared for Hasting's Suburban Addition filed October 16,
1891.
RAU will set a number of durable right -of -way monuments and file a Record of Survey Map,
since the evidence is sparse and may be lost soon.
Task 4.1 Deliverables
• Survey Control Data Sheets — (1 sheet at 1 "= 400')
• Boundary and topographic mapping (9 Sheets at 1 "= 50'), including:
o Boundary location of properties, including the recycled water storage pond,
where Record Maps exist.
o Boundaries of street or state highway rights -of -way where the Phase 3 pipeline
route is in close proximity to project limits.
o Approximate private property boundaries where no Record Maps exist, or
where monuments of record are not found.
• Electronic Files in AutoCAD Civil 3D .dwg file format with point files and the DTM surface
model.
• Record of Survey Map, which will extend from the southern end of Babcock Lane near
Talmage Road to East Gobbi Street, showing existing monuments in or near Talmage
Road and East Gobbi Street. It will also show new right -of -way monuments set at
intervals of 500 to 700 feet along Babcock Lane. The monuments will consist of 5/8"
diameter reinforcing bars with a 2 inch diameter aluminum cap stamped "ROW — RCE
21908 ". The map will be submitted to the County Surveyor for checking and then to the
County Recorder to be recorded.
Task 4.1 Assumptions
• Potholing of the underground facilities at the route of the recycled water pipeline is not
included in this task;
• Title reports shall be obtained on an as- needed basis and all fees for same shall be
reimbursed as an added "Expense ", or will be supplied by the City of Ukiah at no cost;
• Mapping will be consistent with deeds and maps of record; no significant discrepancies
or ambiguities requiring a Record of Survey Map to disclose them will be required
(unless otherwise included);
• Mapping of wetland delineations or other botanical or biologic resources, except
obvious riparian vegetation, is not included;
• Fees for checking and recording are not included in the fee estimate.
Task 4.2 - Geotechnical and Corrosion Investigation
The ENGINEER's subconsultant LACO Associates (LACO) will review available existing geologic
maps, soils reports, and geologic reports forthe project area. LACO will review the project area and
markthe boringlocationsfor Underground Service Alert (USA).
11
For the Phase 3 pipeline route, LACO will perform a total of 24 borings along the alignment (18 to
a depth of 10 feet in the area of the pipeline trench, and 6 up to 50 feet deep in the area of jack
and bore crossings). For the revised footprint for the recycled water storage pond, LACO will perform a
further 10 borings (6 between 30 and 50 feet deep in the area of the pond, and 4 to a depth of 10 feet in
potential borrow areas). LACO will install temporary standpipe piezometers in select borings to
measure relaxed groundwater elevations, log the borings, and obtain disturbed and relatively
undisturbed soil samples for laboratory testing. Sampling locations /depths will be determined in
the field by the project geologist based on subsoil conditions encountered.
A laboratory testing program will beconductedto characterize the soil properties. LACO will
perform laboratory tests on selected soil samples that may include direct shear and /or triaxial
shear strength, particle size, moisture content, dry density, Atterberg limits, consolidation, and
corrosion potential (resistivity, pH, sulfate, chloride, and redox potential).
LACO will perform engineering evaluations to develop conclusions and recommendations
regarding geologic hazards affecting the proposed improvements, excavatability, thrust -block
bearing capacity, and corrosion potential of soils.
LACO will prepare a Phase 3 TM, as a supplement to the Phases 1 and 2 Geotechnical Report
that documents the results of the geotechnical investigation and addresses requirements of
both the California Building Code and the Mendocino County Grading Regulations (current
versions as of the date the TM is prepared). The TM will include soil logs, results of laboratory
analysis, results of geohazard evaluation, and geotechnical recommendations to support design
and construction of proposed improvements.
Task 4.2 Assumptions
• A maximum of 34 geologic borings will be performed.
• An environmental assessment oranyexplorationforthe presence orabsenceofany
hazardous ortoxic materials is not included.

LACO will contact USA, priortofield survey, so that utility location markings can besurveyed and
shown on the plans. LACO will identify all utilitieswithin the project corridor and walk the sitewith
12
each contactto verify preliminary locations and identify potential conflicts. Notify all utility contacts
and provide them with a set of30% plans. A utility contact log will be maintained. Develop
potholing plan andstartcoordinatingwith utilitycontactsandtheOWNERforpotholingservices
Task 4.4 - Identification of Permit and Easement Requirements
Basedonthefinalalignment ,diameters, and construction methods, permitandeasement
requirements will be identified and confirmed. A list of identified required permits will be provided.
Task 4.5 - Environmental Studies and IS / MND Addendum
The ENGINEER'S sub consultant SMB Environmental will prepare an Addendum to the City of
Ukiah's Initial Study /Mitigated Negative Declaration (IS /MND) on its Recycled Water Project
which was approved by the City Council on June 5, 2013. The addendum will focus on the
proposed changes in storage capacity and location. The Addendum will be prepared and will
include an updated biology and cultural resources investigation to meet the requirements of the
State Water Resources Control Board through the State Revolving Fund (SRF) loan program. The
Addendum will undergo a 15 -day public review period and will need to be formally adopted by
the City Council through a Resolution process. Once adopted by the City, SMB Environmental
will file the Notice of Determination with the State Clearinghouse and the County of Mendocino
