5.3 Hopyard Dougherty Rd Traffic Signal
4:17 Dill3CP‘P 62 00-44D AGENDA STATEMENT Meeting Date: December 27, 1982 SUBJECT Traffic Signal Agreement - Hopyard/Dougherty Road at I-580 EXHIBITS ATTACHED : Environmental Negative Declaration; Letter from CalTrans dated 12/1/82; Letter from TJKM dated 12/17/82 & Attachments; Traffic Signal Agreement; Resolution RECOMMENDATION 1 ) Make necessary finding and approve Negative Declaration. 2) Adopt Resolution authorizing Mayor to execute traffic signal agreement with the City of Pleasanton. FINANCIAL STATEMENT: Estimated project cost of $175,000 and future modification, maintenance and operation will be borne by the City of Pleasanton. DESCRIPTION : At its meeting of September 13, 1982, the City Council approved in concept the installation of a traffic signal on Dougherty Road and I-580 along with related improvements. The City Council. directed Staff to work out an agreement with the City of Pleasanton • and proceed with the environmental review. The City Council 's approval of this traffic signal was conditioned on the installation of a traffic signal on the south side of I-580 at the same time. Since that meeting, Staff and the City Attorney have developed an agreement with repre- sentatives from the City of Pleasanton (see attached). The significant conditions of that agreement are as follows: 1 . All costs of installation, maintenance, operation and future modifications will be borne by the City of Pleasanton. 1 2. The proposed traffic signal will not be made operational until the traffic signals at the intersection of Hopyard and the I-580 eastbound off ramp are installed and made operational . 3. The proposed signal will be interconnected with the Dublin Dougherty Signal subject to approval by State of California Department of Transportation. 4. Dublin retains the right of final review on the project plans, and the phasing of the proposed signal and the Dublin Boulevard Dougherty Road signals. The attached agreement is mutually acceptable to both the City of Pleasanton and the City of Dublin Staffs. In addition to the agreement, the Dublin Planning Director has conducted an environmental review of the signal project and has prepared a Negative Declaration which finds that the project will not have a significant effect on the environment. Staff has published adequate notice regarding the Negative Declaration, and has received comments from the State of COPIES TO: City of Pleasanton ,.+ TJ KM Trrne nin /1 AGENDA STATEMENT - Traffic Signal Agreement Page 2 California Department of Transportation (see attached) . Mr. Chris Kinzel , TJKM has responded to the comments of CalTrans. Staff believes that Mr. Kinzel 's response adequately addresses the comments of CalTrans. It is Staff's recommendation that the City Council make the necessary findings and approve the Negative Declaration, and further, adopt a resolution authorizing the Mayor to execute the traffic signal agreement with the City of Pleasanton. t-2 -025 THE CITY OF DUBLIN P.O.

Upon review, the following comments were generated: 1 . We are coordinating the project with the City of Dublin and the City of Pleasanton. We have no objection to the project providing that Caltrans is not responsible for any project construction cost. Our understanding is that this is a locally funded project paid for by the City of Pleasanton. 2. For our Highway Operations Branch review, we would like a plan of the proposed westbound off-ramp/Dougherty Road signalized inter- section, plus TJKM's traffic report. 3. "Factlal Explanation" says the Dublin Blvd./Dougherty Road inter section will remain at Level of Service "E". At this LOS, will there be northbound Dougherty Road back-ups from this intersection through the off-ramp intersection? 4. For our Transportation Planning Branch review we need diagrams showing existing and proposed geometrics and signal locations, also traffic diagrams showing ADT and AM and PM peak hour volumes for the existing and proposed lane configurations and with existing and full build-out volumes of the North Pleasanton Area as analyzed by TJKM, per refer- ence under "Factual Explanation" to item B.6.1 .

Reynolds District CEQA Coordinator CalTrans District 4 P. 0. Box 6310 San Francisco, Ca. 94120 Dear Mr. Reynolds: This is in response to your December 1, 1982, letter to Laurence Tong, Planning Director of the City of Dublin regarding the negative declaration for the I-580/Dougherty Road Westbound 0ff-Ramp Traffic Signal (your file Ala-580-19.86) . Mr. Tong has asked me to respond directly to you concerning your comments. 1. Your understanding that the proposed project is entirely funded by the City of Pleasanton is correct . 2. We have enclosed copies of the draft project report for the proposed improvement , including a plan of the improvements . The report was prepared in September but not forwarded to you until this time pending environmental clearance by the City of Dublin. As has been the case on past projects involving TJKM and your highway operations branch, we are available to respond to any additional technical questions CalTrans may have. 3. The Dublin Boulevard/Dougherty Road intersection is currently operating at Level of Service E and is projected to remain at that level . The principal point of congestion in the intersection at the present time is back-up from the eastbound to southbound right turn movement . The reverse movement , the northbound to westbound left turn and its associated northbound through and right turn movements have a satisfactory combination of adequate capacity and distance from the proposed signal to preclude back-ups into the new signalized intersection . 4. We have enclosed the a .m . and p .m . peak hour volumes at the intersection along with the 2005 design volumes for the a .m. and p.m. peak hours . Generalized short-term lane configuration changes are shown in the plan included in the project report . Long-term proposals for the area , currently being coordinated with Clarence Yee , are in accordance with lane configurations proposed in the North Pleasanton Traffic Study Volume 3, enclosed. Mr. Yee has received working documents of the proposed improvements to the 675 Ygnacio Valley Road,Suite 211 /Walnut Creek, California 94596 • (415)938-2200 Darnall Reynolds -2- December 17 , 1982 Hopyard Road interchange. We believe that the City of Pleasanton is in general concurrence with the conceptual details of the Hopyard interchange but the City of Dublin has not formally reviewed or approved the proposed interchange modification . It is our understanding that this interchange improvement along with others in the Dublin/Pleasanton area will be the subject of a comprehensive CalTrans prepared EIS. Existing and proposed traffic signal locations in the general area are also indicated in Volume 3. We will be happy to respond to any additional questions that may arise.

The City will advertise and administer the contract under an encroachment permit. The cost of this project is to be funded 100 percent by private monies. Project Category This is a Category 5 project because the work involved will have minimal economic, social or environmental significance. Background Flo? The City of [ rb-1-i-n requested that the traffic signal be installed and the intersection improved to mitigate existing traffic congestion and provide additional traffic capacity for a recently approved industrial development in the adjoining City of Pleasanton. The signalization and improvements were earlier required by the City of Pleasanton as a condition of approval for the project until it was discovered that the intersection was in the jurisdiction of the City of Dublin . Subsequently, the City of Dublin concurred with the previous mitigation requirements and formally assumed responsibility for administrating the project. 1 The industrial development referred to is the 573 acre Hacienda Business Park which is located between Hopyard road and Santa Rita Road in the City of Pleasanton as shown in Figure 1. The project was approved by the Pleasanton City Council on May 19, 1982, and is described as Planned Unit Development 81-30. -1- The City of Pleasanton required a comprehensive traffic study to be done in conjunction with the approval of the Hacienda Business which analyzed the complete traffic implications of the build-out of North Pleasanton. The traffic study concluded that the existing local transportation system would need upgrading and proposed substantial roadway improvements both in the City of Pleasanton and on State right-of-way. A private assessment district is being formed to fund the street improvements with a total estimated cost of 81 million dollars. Two of the proposed roadway improvements will have direct effects on the Dougherty Road/Hopyard Road interchange to I-580. Hopyard Road will be widened between I-580 and Valley Avenue from four to six lanes, and extensive capacity improvements are proposed for the interchange including a second overpass structure. Construction on Hopyard is already in progress and the conceptual designs for the Hopyard Road interchange modification have been prepared. For these reasons, the proposed traffic signal installation and related roadway widening is considered to be an interim project. Existing Facility At the location of the intersection proposed for signalization , Dougherty Road is a two-lane asphalt concrete roadway which serves as an arterial road. The westbound off-ramp from I-580 that intersects Dougherty Road is a single lane asphalt concrete ramp which splits to allow 2 free flowing right-turn lanes onto northbound Dougherty Road and a single lane regulated by a stop sign for left turns onto southbound Dougherty Road/Hopyard Road toward the City of Pleasanton. North of the intersection, Dougherty Road has five lanes ( three northbound, two southbound) and a raised concrete median. Dublin Boulevard, an arterial street that serves the Dublin central business district intersects with Dougherty approximately 800 feet north of the proposed signalized intersection. The Dublin-Dougherty intersection is regulated by 4-phase traffic signals. -2- South of the intersection Dougherty Road continues as a two-lane road and crosses the freeway overpass into the City of Pleasanton where the road changes names to Hopyard Road. A third element of the intersection is the westbound on-ramp to I-580 from southbound Dougherty Road which begins about 120 feet north of the intersection with the westbound off-ramp. Traffic Data Existing Conditions Twelve hour volume counts were taken at the intersection on August 25, 1982, on all approaches. There were 15,518 vehicles on Dougherty Road in both directions and 1 ,308 vehicles from the off-ramp. From these counts, the highest eight one-hour volumes were collated and compared to the traffic signal warrants as shown on the attached Traffic Signal Evaluation Sheet. As can be seen, the exiting volumes satisfy 97% of Warrant 1 , and they satisfy 100% of Warrant 2 for Interruption of Continuous Traffic. The a.m. and p.m. peak hour turning movements were recorded in July 1982. Excessive delays were observed for vehicles on the off-ramp with queues in the morning of 18 to 20 vehicles and 8 to 10 vehicles in the evening peak hour. The delay time for these vehicles in the evening peak hour was as long as 5 minutes . Using a capacity analysis that assumes a two-phase signal operation, the p.m. volume-to-capacity ratio is 1.10 which corresponds to Level of Service F. Apparently, the actual hourly lane volume capacities for the approaches are higher than the assumed capacities (through movement = 1 ,500 vehicles per lane hour, turning movement = 1,250 vehicles per lane hour. The accident history at this intersection for the past 3 years is unavailable at this time. At a later date, these records will be analyzed to determine what, if any, problem accident patterns exist. -3- • Future Conditions A traffic impact study was done as part of the comprehensive environmental impact review for the Hacienda Business Park. The study entitled North Pleasanton Traffic Study, Volume 3, March 1982 by TJKM of Walnut Creek analyzed the traffic consequences of full build-out of the North Pleasanton area. The future build-out daily volumes at this intersection were estimated i to be 26,200 vehicles per day (vpd) on Dougherty Road (an increase of about 2,850 vpd) and 3,025 vpd on the westbound off-ramp (an increase of about 1,800 vpd) . The primary route for traffic bound for the North Pleasanton developments will be from the west on 1-580 to the south on Hopyard Road. Thereby, the interchange ramps serving those moves will have the greatest impacts. Ultimately, the interchange is proposed to be modified to provide a new three-lane overpass on the east side of the existing structure along with widening on several ramps . The ultimate improvements at the intersection of the westbound off-ramp and Dougherty Road in conjunction with the new overpass structure will involve additional widening to the east side of Dougherty Road beyond the improvements proposed for this project. Proposal Description The following measures are proposed to mitigate the excessive delays at the intersection of Dougherty Road and I-580 westbound off-ramp. 1. Widen the Dougherty Road approaches to provide two through lanes on each approach. 2. Widen the westbound off-ramp to provide two left turn lanes with an 8-foot breakdown shoulder. -4- 3. Install complete traffic signal system with multi-phase full traffic actuated controller. The traffic signal will operate in two phases as shown on the preliminary plan. 4. Construct new raised concrete island to serve as a protected area on which to mount traffic signal hardware and to provide direct line-of-sight for optically programed traffic signal equipment for the southbound Phase 2 approach. 5. Install wood post guardrail to protect traffic signal controller and adjacent traffic signal standard. 6. Install cantilever "Prepare to Stop" warning signs south of the intersection to warn northbound vehicles of upcoming traffic signal . The flashing beacon is required because the sight distance is reduced by the freeway overpass structure which begins 400 feet south of the intersection. 7. Install interconnect equipment so that the new signal can be coordinated with the existing Dublin-Dougherty intersection approximately 800 feet to the north. 8. Install pavement markers, signs and lane striping. Project Reviews -5- Right of Way No additional right of way is required . I have reviewed the right-of-way data contained in this project report and find it to be complete, current and accurate. R. A. Speck Deputy District Director Right of Way Utility Relocation No utility relocation is anticipated. Distribution of Maintenance Cost The Cities of Dublin and Pleasanton have entered into an agreement in which the City of Pleasanton agrees to pay for the City' s share of maintenance costs. The City of Pleasanton is establishing a maintenance district to fund the expenses for various maintenance activities, including traffic signals. Environmental Statement The City of Dublin approved a negative declaration of environmental impacts of this Project (No. ) on , 1982. A copy of this document is attached. -6- • Estimate of Cost A detailed estimate is not available at this time. It is estimated that the cost of the project will be approximately $175,000. Financing The cost of the roadway improvements and the complete traffic signal installation will be funded. 100 percent by the developers of the Hacienda Business Park in the City of Pleasanton. Recommendation It is recommended that this project be approved so that its implementation may proceed. The design will be prepared by a private consultant. It is also recommended that after the State approves the final plans, the City be allowed to advertise the project and install the traffic signals by encroachment permit. Attachments 1.
