cities use something other than modeling or if this was the only strategy to get information. Deputy Director Tassano said this was the best practice. Pleasanton has the most involved model of any local agency he has seen and is the best way to gather information. Councilmember Thorne asked if staff were requested to do additional modeling, would the cost be covered under the existing professional services agreement. Deputy Director Tassano replied that the models set forth in the staff report are definitely covered. If 45-50 more runs are necessary, it may be necessary to draft a new agreement. Councilmember Thorne referred to the three left turn lanes from Santa Rita onto Valley Avenue and asked what would happen to Valley Avenue? He questioned if traffic moved quicker through the intersection if it would just back up on Valley? Deputy Director Tassano said one of the difficulties in reviewing levels of service is that the congestion points are always at the intersections. Traffic from a three lane road could turn onto a two lane road so long as there were no congestion points on the two lane road. Councilmember Thorne referred to the review of problems on Highway 84. He felt it was necessary to have an agreement among the cities involved in the Triangle Study regarding improvements before any consideration should be given to Stoneridge Drive. Mayor Hosterman said it has always been contemplated that at the end of the study there would be some sort of agreement among the agencies involved for purposes of lobbying with one voice for getting the necessary funding for the infrastructure improvements. Councilmember Thorne asked what was the East Dublin Properties Roadway Network? Deputy Director Tassano said that was the specific plan for East Dublin and staff has reviewed it. Councilmember McGovern believed the biggest decision for the city of Pleasanton is regarding its land use and circulation elements. She shared her concerns about accountability. She felt when future development is reviewed, there needs to be some safety valves in the conditions, especially with regard to funding mechanisms. She was concerned that if the traffic model was incorrect, there might not be funding available for a correction. She suggested adding that in all the conditions of new development. Commissioner Blank agreed and suggested posting a bond for relief in the event the traffic engineer's plan fails the city and nearby neighborhoods could get some relief. Councilmember McGovern expressed concerns about traffic signal synchronization and asked if there could be a staff presentation on that subject. City Council Minutes 5 January 30, 2007 Joint Workshop
