13. Review of the Tri-Valley Triangle Traffic Study final report Rob Wilson, Director of Public Works gave the staff report and noted the cities of Pleasanton, Livermore and Dublin, as well as the County of Alameda, have been involved with developing the Tri-Valley Triangle Traffic Study intended to evaluate and prioritize future regional traffic projects in the area mainly bounded by I-580, I-680 and State Route 84 (the triangle). To provide policy direction, the agencies established a Policy Advisory Committee (PAC), made up of elected representatives of the participating cities and the County. The PAC met on March 26, 2007 and adopted a final recommendation and the purpose of this report is to review its recommendation. Mr. Wilson noted the Study identified 13 regional traffic improvement projects which were placed in two implementation schedules. The only difference between the two implementation schedules, labeled Hybrid 1 and Hybrid 1A, is that Hybrid 1A includes the State Route 84 widening project from Pigeon Pass to I-680 including interchange and auxiliary lane improvements at I-680 and State Route 84. He noted staff has concerns with the final recommendation. The purpose of the Study, as adopted by the PAC, stated that a plan would be developed by "consensus." Instead, the plan being recommended was selected by majority vote. In response, staff recommends sending a letter to the CMA, with forwards to both the Plans and Program Committee and the Board, highlighting the following points: 1. The Study is not a consensus document as stated in the Study purpose. All PAC members have unanimously supported the consensus concept and deviating from this purpose at this time is counterproductive to addressing regional traffic issues. 2. The City will request that all future traffic modeling include both "with" and "without" State Route 84 improvements, in order to determine the level of impact of the projects on the City of Pleasanton's local traffic. 3. The City will need to more closely scrutinize all regional development projects which are planned without State Route 84 improvements. 4. Without a plan for State Route 84 improvements, the City will proceed with pending litigation regarding the I-680 northbound HOV lane project, since it will bring additional traffic to the I-680/1-580 project and result in additional cut through traffic in Pleasanton. Mayor Hosterman gave a history of the process and noted there are a number of regional agencies who came together two and half years ago with this Study funded largely by all involved. The CMA for Alameda County led the Study and at that time the purpose of the Study was to try to identify those freeway infrastructure improvements which would collectively benefit the entire region and get the failing surrounding freeway system moving and working. City Manager Fialho noted that State Route 84 has been found, when modeled, to alleviate cut-through traffic inside the city limits of Pleasanton. Every analysis that the City and CMA have done indicates that construction of Route 84 from I-680 to Pigeon Pass and beyond to the proposed interchange, also alleviates traffic on I-680, but more importantly I-580. Mayor Hosterman pointed out that staff from the City and the Congestion Management City Council Minutes 5 April 3, 2007
