(Report attached) Member Seanor was contacted by Ms. Laura Cook in regards to the intersection of Mill and Carolyn �., Streets who had concerns about tall and oversized trucks parking on the street and at times blocking her TEC 5/10/11 Page 1 of 3 driveway. She cited City code section 7154.5. Member Seanor requested she send a letter stating her requests. Will Heimberg, neighbor of the affected area was present. Discussion ensued with the following comments: • Member Taylor commented that there have been several complaints regarding this same issue. • Mr. Heimberg commented that a chipper and tree truck are parked in front of each homeowner's house as is his truck. Mr. Heimberg also commented that in the past he has parked his truck on Carolyn Street but started parking it in Mill Street because his diesel tank was siphoned. • Mr. Heimberg said he does move his vehicles every day and utilizes them but is more than happy to comply with whatever is safe but the ordinance must be enforced evenly. Mr Heimberg said safety is the issue and the 6 foot vehicle height ordinance not address the safety issue. • Vice -Chair Baxter commented that looking at the photos', /�d be a sight hazard to see oncoming traffic. j/ . • Member Seanor commented that he thought the try / n parked in front of Ms. Cook's house.

Chair Turner requested a' t "'he bike corral. Member Seanor commented that several council members requested that the '� orks Department look into removing up to 3 parking spaces on Standley Street near Patrona. city will build an ADA approved surface to extend the seating and have room for bicycle parking. Member Kageyama said he had been researching a modular decking system that would rest on the surface of the pavement. Vice -Chair Baxter commented that the pavement on Airport Park Blvd is still deteriorating. The curb section appears to be separating from the pavement. Member Seanor commented that the City currently has a project in place that will fix the pavement and widen some of the turns. Member Kageyama informed the commission that the Clara Avenue project is complete; bulb -outs for crosswalks have been installed as well as new storm drains. Additional funds in the future will allow the } sidewalks to be repaired as well as more crosswalks and bulb -outs to be installed. Vice -Chair Baxter TEC 5/10/11 Page 2 of 3 congratulated Member Kageyama on his management of the project and for coordinating efforts amongst agencies. 8.

Jar TEC 5/10/11 Page 3of3 CITY OF UKIAH MEMORANDUM DATE: February 14, 2012 TO: Traffic Engineering Committee FROM: Rick Seanor, Deputy Director of Public Works SUBJECT: Discussion and Possible Action Regarding Gobbi St. — Oak Manor Dr. — Babcock Lane Intersection Agenda Item 5a. REQUEST: The Traffic Engineering Committee (TEC) received a request (Attachment "A ") from Tim and Krista Todd, 595 Oak Manor Drive, requesting evaluation of the intersection of Gobbi Street — Oak Manor Drive — Babcock Lane. In particular, Mr. & Mrs. Todd are concerned with the safety of their house because there have been two reported collisions where vehicles have run into their house. The traffic collision report for the collision at the Todd residence which occurred on December 25, 2011 stated that the driver had been drinking. A photo map of the area is included for reference as Attachment "B ". DISCUSSION: The Gobbi Street — Oak Manor Drive — Babcock Lane Intersection Realignment project was completed on December 13, 2010. This project realigned Babcock Lane with Oak Manor Drive through construction of two box culvert crossings of Gibson Creek. The intersection is signed with all -way STOP signs. In addition, each of the four street approaches is signed with STOP AHEAD signs. Oak Manor Drive is currently posted for a 25 -mph speed zone. Gobbi Street from Oak Manor Drive to Leslie Street is posted for a 30 -mph speed zone. Gobbi Street, east of its intersection with Oak Manor Drive, is a County road. Howard Dashiell, Mendocino County Director of Transportation, provided a written response to Mr. & Mrs. Todd regarding this intersection. Mr. Dashiell's letter is included as Attachment "C ". Mr. and Mrs. Todd have suggested a flashing red signal at this intersection. Per the Manual for Uniform Traffic Control Devices, a flashing red beacon is not warranted at this intersection. Also, Mr. and Mrs. Todd have suggested installation of bollards to protect their house. Staff does not support construction of bollards in the sidewalk or at the back of curb. However, construction of a fence, block wall, or bollards in back of the sidewalk would be acceptable to the City, provided that the height of the constructed items does not exceed three feet. RECOMMENDATION: 1) Discuss and provide recommendation for possible changes. 2) Refer to staff for further analysis. cc: file Jane Chambers City Manager 300 Seminary Avenue Ukiah, CA 95482 Re: Safety Concerns Dear Jane: Attachment # %%A Tim Todd, Computer Lab Technician, Mendocino College Krista Todd, RN, Ukiah Valley Medical Center 595 Oak Manor Drive Ukiah, CA 95482 RECEIVED 707/463 -2037 707/489 -7280 DEC 2 8 2011 CITY OF UKIAH DEPT. OF PUBLIC WORKS December 26, 2011 - It is with much concern and that we write this letter. We would like to meet and discuss what can be done to improve the safety of our house and of the Gobbi Street /Oak Manor Drive intersection. On December 25th, a drunk driver crashed into our house (Police report pending, case # 11- 3611). Thankfully no one was injured in the crash. Due to an illness, our Christmas festivities were cancelled. If they had not been cancelled, there would have been children sleeping in the bedroom that the car crashed into. It is highly likely that they would have been critically injured or killed. This is the second incident in 3 years in which a car has crashed into our house (The first incident was reported by the previous owner). The vehicles in both accidents followed the same trajectory path and both crashed into our west facing bedrooms. Consequently, we no longer feel safe having anyone stay in these bedrooms. Should we have children of our own, we do not have a safe place for them to sleep. Because of the recent construction at the Gobbi Street /Oak Manor Drive intersection, it is now used as more of a thoroughfare. The angles of the stop signs and the widening of the intersection make this especially dangerous at night. Stop signs at night are difficult to see, especially for drunk drivers or those traveling at a high rate of speed. We are eager to work together for possible solutions to these safety concerns. Would bollards and a flashing red signal be a possibility? We thank you for your consideration and look forward to hearing from you.

Our local road staff makes every attempt to regularly review our roads and our traffic safety engineer field reviews all 1016 miles of road — annually reviewing one third of these roads, on a rotation. However, we need the eyes and ears of the public to bring matters to our attention with so many roads to oversee. 2) We are sorry for the destruction of property caused by the recent accident (reckless driver) striking you house. We agree with you that a more tragic outcome was avoided because the bedrooms were not occupied. 3) As we discussed when you delivered your letter to my office, the subject intersection is entirely within the City of Ukiah. Gobbi Street does cross to county jurisdiction within a short distance where it becomes East Gobbi Street. Therefore, MCDoT does not control or have the responsibility for implementing the suggestions made in your letter. Nevertheless, because we spoke, and because MCDoT believed we needed to review the conditions to determine if we might be a part of the solution —I did field review of the intersection in the dark with the following observations: a. The City has recently improved the intersection in conjunction with their bridge project. The "squaring off' the four way stop with Babcock Lane which previously approached at an angel is consistent with good traffic engineering and standard practice in the industry. We note the City is using current standard retro reflective stop signs and pavement markings consistent with current industry standards. If the city were to consider some advance warning markings or signage which needed to be on the county legs of the intersection (Babcock and Sheet 2 of 2 Pietila Letter, 3 -8 -11 East Gobbi) the County would gladly corporate. However, it appears the City's intersection is proper. b. Regardless of signage issues the accidents in question occurred when eastbound Gobbi Street traffic failed to negotiate the left turn onto Oak Manor Drive — apparently in violation of several vehicle code provisions — speeding, running a stop sign and alleged impairment. Frankly, in is my opinion that the flashing red light you suggest would not correct that — at least I would not trust a flashing red light to protect children sleeping in the front bedrooms of your house. Traffic engineering research advises flashing lights for regional roads where thru traffic drivers are not aware of traffic controls. Nationwide studies have shown that local traffic become so accustomed to flashing lights that they have little benefit on local streets and roads. Furthermore, flashing lights in residential areas cause annoying background light pollution. c. In my opinion your idea of a barrier (bollards) is the sort of solution that would give me peace of mind as to safety of my house and occupants. However, guard rails would be the industry standard (not bollards). I would not recommend either bollards or guard rails on the street side of the sidewalk curb returns in front of your house. This is not conducive to standard design and would present a hazard to westbound Gobbi Street traffic turning right onto Oak Manor Drive that could possibly side swipe a bollard. \ My suggestion — and it is only a suggestion, as this property is not in the county - would be that you have a fence or wall professionally designed and constructed in your front yard behind the back of the sidewalk that could withstand an impact consistent with the two accidents you cite. It is likely that no design would protect from all possibilities (e.g. runaway truck, etc.) but having my own fence or wall with deep foundations of concrete and steel would be most reassuring to me. Please feel free to contact me with any questions or comments. Very truly yours, Howard N. Dashiell cc.

School St. and along North Oak Street between Standley Street and Smith Street Agenda Item 5b. REQUEST: Captain Trent Taylor, Ukiah Police Dept., notified staff of a conflict in parking designation at the Triple -S Camera store located at 260 S. School St. At this location there are two 24- minute parking spaces, indicated by green curb paint. Also there is a posted sign designating 1'/2 hour parking adjacent to the green curb. Captain Taylor has spoken to the owners of Triple -S Camera regarding this situation. The Triple -S Camera store owners do not object to the removal of the 24- minute parking. With the closing of the downtown Post Office, staff has requested to remove the 24- minute parking along North Oak Street between Standley Street and Smith Street and to establish 1'/2 hour parking in this block. DISCUSSION: For the 260 S. School St. there are two options to more correctly identify the parking designation at this location. The first option would be to remove the existing 24- minute parking designation. The second option would be to install appropriate signage to designate the 24- minute parking zones. Per Attachment "A ", City Code section 7161, twenty four minute parking zones are designated by either ordinance or resolution. Therefore, in order to remove the twenty four minute parking zones, staff will need to submit the TEC's recommendation on this matter to City Council. RECOMMENDATION: 1) Recommend to the City Council the removal of the 24- minute parking zone (two parking spaces) at 260 S. School St. and to establish 1'/2 hour parking for the same two spaces; 2) Recommend to the City Council the removal of the 24- minute parking along North Oak Street between Standley Street and Smith Street and to establish 1'/2 hour parking in the same block; 3) Refer to staff for further analysis. cc: file s aC9 la 0 0 � U U a� CW (� o "U o M t9 C� W Z O x 00- t �O � a ,N�� v fib � s S a s W -� � � V O d O a a� i f d � U z � CITY OF UKIAH MEMORANDUM DATE: April 14, 2009 TO: Traffic Engineering Committee FROM: Rick Seanor, Deputy Director of Public Works PV SUBJECT: Discussion and Possible Action Regarding Request for STOP signs on East Gobbi Street at Oak Manor Drive Agenda Item 5b. REQUEST: The Traffic Engineering Committee (TEC) received a letter from residents on Oak Manor Drive requesting posting of STOP signs on East Gobbi Street at Oak Manor Drive. Please refer to the request, Attachment "A ". A photomap of this intersection, Attachment "B ", has been provided for reference. A photograph of the intersection is provided as Attachment "C ". DISCUSSION: The residents cited recent traffic accidents as well as vehicles travelling at high rates of speed as reasons to support the requested STOP signs. At this intersection there is an existing STOP sign for southbound traffic on Oak Manor Drive. East Gobbi Street from Leslie Street to Oak Manor Drive is posted for a 30 mph speed zone. East of Oak Manor Drive, East Gobbi Street is posted with a 25 mph speed zone sign. The City of Ukiah is currently working on the design for a project to realign the intersection of East Gobbi Street — Oak Manor Drive — Babcock Lane. The project is scheduled to be advertised for bids this summer. Once constructed, Oak Manor Drive and Babcock Lane will align north to south. COLLISION HISTORY: Staff reviewed the Statewide Integrated Traffic Records System (SWITRS) to determine if there were any collisions at the intersection of East Gobbi Street at Oak Manor Drive. During the period from January 1, 2004 through June 30, 2007 there was only one reported collision at the intersection. However, staff is aware of two accidents at this intersection within the last year. In one accident a vehicle turning from Gobbi Street onto Oak Manor Drive ran into a street light. Another accident involved a vehicle running into the house located at the corner of East Gobbi Street and Oak Manor Drive. STOP SIGNS: Attached for reference are selected pages from the Manual on Uniform Traffic Control Devices ( MUTCD) and the MUTCD 2003 California Supplement regarding multi -way STOP sign applications (Attachment "D "). Also, please note Attachment "E ", Section 7061 of the City Code which authorizes the city traffic engineer (TEC) to post STOP signs.

Gobbi Street Dear Committee Members, We, the residents and homeowners of the Oak Manor neighborhood, are requesting that 2 stop signs be installed on eastbound and westbound directions of E. Gobbi Street at the corner of Oak Manor Drive. Cars traveling eastbound on E. Gobbi, turning left (northbound) onto Oak Manor Drive, consistently drive too fast. Residents attempting to back out of their driveways onto Oak Manor Drive and school children using these sidewalks are constantly at risk of being hit by these fast moving cars. Recently, there have been 2 serious car crashes on this corner. One car crashed into and took out the light pole located on the sidewalk, and another car actually crashed into the house damaging the studs and drywall in two bedrooms and taking out 6 feet of the concrete foundation. Will you please give some attention to this mater, before some person gets hurt?

Larger signs may be used when appropriate. 2. Dimensions are shown in millimeters followed by inches in parentheses and are shown as width x height. Section 2B.05 STOP Sign A.U.0cations Guidance: STOP signs should be used if engineering judgment indicates that one or more of the following conditions exist: A. Intersection of a less important road with a main road where application of the normal right -of -way rule would not be expected to provide reasonable compliance with the law; B. Street entering a through highway or street; C. Unsignalized intersection in a signalized area; and/or D. -High speeds, restricted view, or crash records indicate a need for control by the STOP sign. Standard: Because the potential for conflicting commands could create driver confusion, STOP signs shall not be installed at intersections where traffic control signals are installed and operating except as noted in Section 4D.01. Portable or part -time STOP signs shall not be used except for emergency and temporary traffic control zone purposes. Guidance: l STOP signs should not be used for speed control. J STOP signs should be installed in a manner that minimizes the numbers of vehicles having to stop. At intersections where a full stop is not necessary at all times, consideration should be given to using less restrictive measures such as YIELD signs (see Section 213.08). Sect. 213.05 November 2003 2003 Edition M A61 VUL P� Vt'1 I"1 pt o., rrKf F1 G CflYi +t Page 2,B--t Once the decision has been made to install two -way stop control, the decision regarding the appropriate \ street to stop should be based on engineering judgment. In most cases, the street carrying the lowest volume of > traffic should be stopped. A STOP sign should not be installed on the major street unless justified by a traffic engineering study. Support: The following are considerations that might influence the decision regarding the appropriate street upon which to install a STOP sign where two streets with relatively equal volumes and/or characteristics intersect: A. Stopping the direction that conflicts the most with established pedestrian crossing activity or school walking routes; B. Stopping the direction that has obscured vision, dips, or bumps that already require drivers to use lower operating speeds; C. Stopping the direction that has the longest distance of uninterrupted flow approaching the intersection; and D. Stopping the direction that has the best sight distance to conflicting traffic. The use of the STOP sign at highway - railroad grade crossings is described in Section 8B.08. The use of the STOP sign at highway -light rail transit grade crossings is described in Section 10C.04. Section 2B.06 STOP Sign Placement Standard: The STOP sign shall be installed on the right side of the approach to which it applies. When the STOP sign is installed at this required location and the sign visibility is restricted, a Stop Ahead sign (see Section 2C.29) shall be installed in advance of the STOP sign. The STOP sign shall be located as close as practical to the intersection it regulates, while optimizing its.. visibility to the road user it is intended to regulate. STOP signs and YIELD signs shall not be mounted on the same post. Guidance: Other than a DO NOT ENTER sign, no sign should- be mounted back -to -back with a STOP sign in a manner that obscures the shape of the .STOP sign. Support: Section 3A.16 contains additional information about separate and combined mounting of other signs with STOP signs.. Guidance: Stop lines, when used to supplement a STOP sign, should be located at the point where the road user should stop (see Section 3B.16). If only one STOP sign is installed on an approach, the STOP sign should not be placed on the far side of the intersection. Where two roads intersect at an acute angle, the STOP sign should be positioned at an angle, or shielded, so that the legend is out of view of traffic to which it does not apply. Where there is a marked crosswalk at the intersection, the STOP sign should be installed in advance of the crosswalk line nearest to the approaching traffic. Option: At wide - throat intersections or where two or more approach lanes of traffic exist on the signed approach, observance of the stop control may be improved by the installation of an additional STOP sign on the left side of the road and/or the use of a stop line. At channelized intersections, the additional STOP sign may be effectively placed on a channelizing, island. , Support: Figure 2A -2 shows examples of some typical placements of STOP signs. Section 2BA7 Maltiway Stop Applications Support: Multiway stop control can be useful as a safety measure at intersections if certain traffic conditions exist. Safety concerns associated with multiway stops include pedestrians, bicyclists, and all road users expecting other road users to stop. Muldway stop control is used where the volume of traffic on the intersecting roads is approximately equal. The restrictions on the use of STOP signs described in Section 2B.05 also apply to multiway stop applications. November 2003 Sect. 2B.05 to 2BA7 Page 2B -8 2003 Edition Guidance: The decision to install multiway stop control should be based on an engineering study. The following criteria should be considered in the engineering study for a multiway STOP sign installation: A. Where traffic control signals are justified, the multiway stop is an interim measure that can be installed quickly to control traffic while arrangements are being made for the installation of the traffic control signal.. B. A crash problem, as indicated by 5 or more reported crashes in a 12 -month period that are susceptible to correction by a multiway stop installation. Such crashes include right - and left -tam collisions as well as right -angle collisions. C. Minimum volumes: 1. The vehicular volume entering the intersection from the major street approaches (total of both approaches) averages at least 300 vehicles per hour for any 8 hours of an average day, and 2. The combined vehicular, pedestrian, and bicycle volume entering the intersection from the minor street approaches (total of both approaches) averages at least 200' units per hour for the same 8 hours, with an average delay to minor -street vehicular traffic of at least 30 seconds per vehicle during the highest hour, but 3. If the 85th- percentile approach speed of the major- -street traffic exceeds 65 -km/h or exceeds 40 mph, the minimum vehicular volume warrants are 70 percent of the above values. D. Where no single criterion is satisfied, but where Criteria B, C.1, and C.2 are all satisfied to 80 percent of the minimum values. Criterion C.3 is excluded from this condition. Option: Other criteria that may be considered in an engineering study include: A. The need to control left-turn conflicts; B. The need to control vehicle /pedestrian conflicts near locations that generate high pedestrian volumes; C. Locations where a road user, after stopping, cannot see conflicting traffic and is not able to reasonably safely negotiate the intersection unless conflicting cross traffic is also required to stop; and D. An intersection of two residential neighborhood collector (through) streets of similar design and operating characteristics where multiway stop control would improve traffic operational characteristics of the intersection. Section 2B.08 YIELD Sin-(RI-2) Standard: The YIELD ' (R1 -2) sign (see Figure 2B -1) shall be a downward - pointing equilateral triangle with a wide red border and the legend YIELD in red on a white background. Support: The 'YIELD sigri assigns right -of -way to traffic on certain approaches to an intersection. Vehicles controlled by a YIELD sign need to slow down or stop when necessary to avoid interfering with conflicting traffic. Section 2B.09 YIELD Sign Applications Option: YIELD signs may be used instead of STOP signs if engineering judgment indicates that one or more of the following conditions exist: A. When the ability to see all potentially conflicting traffic is sufficient to allow a road user traveling at the posted speed, the 85th - percentile speed, or the statutory speed to pass through the intersection or to stop in a reasonably safe manner. B. If controlling a merge -type movement on tht entering roadway where acceleration geometry and/or sight distance is not adequate for merging traffic operation. C. The second crossroad of a divided highway, where the median width at the intersection is 9 m (30 it) or greater. In this case, a STOP sign may be installed at the entrance to the first xoadway of a divided highway, and a YIELD sign may be installed at the entrance to the second roadway. D. An intersection where a special problem exists and where engineering judgment indicates the problem to be susceptible to correction by the use. of the YIELD sign.
