Mr. Knowles said there are two different issues. It is a tool that makes projections based on certain assumptions and scenarios. It doesn't mean all jurisdictions would agree on the same improvements. Sometimes an improvement would help one city to the detriment of another. The concept of the model is popular enough that Contra Costa County is using this software to prepare the countywide model. Livermore's model is similar and he believed the Livermore staff was using the same database. He related informal discussions among the staff of various agencies and he felt this was the way all would be going with regard to modeling. The Tri- Valley model is a sub-model of the Contra Costa model. Since Contra Costa is using the same software and consultant, he felt all the Valley cities would be using the same model. Mayor Pico referred to a regional meeting among Dublin, Livermore, Pleasanton, BART, CalTrans and other interested parties, to analyze the various transportation projects. They were trying to determine how best to allocate the Proposition 42 funds. At that meeting, the scope of projects was narrowed down to four or five: Highway 84 improvements, 1-580 HOV lanes, BART or other transit to Greenville Road, and on-ramp metering for the freeways. Those are the four major items that we can agree on. We are now trying to determine the phases, timing, and funding of those projects. One question was whether the group wanted to rely on the Pleasanton model in terms of helping to understand the various alternatives and where the most congestion relief can be achieved. The consensus at that time was that they were not comfortable yet, but agreed they would accept it as additional information. He acknowledged the model still has some bugs and needs more testing. Ms. Ayala referred to a figure she had heard that it would cost $500 million for improving Highway 84 to four lanes. How many billions are necessary for the four projects? Mayor Pico did not believe billions was accurate. BART would cost about $760 million and Highway 84 about $250-300 million. The cost of HOV lanes is difficult to estimate because it includes costs for BART rights of way and other related infrastructure. He felt it could be almost $250 million. Ramp metering could be installed throughout the entire 580 corridor for less than $15 million. There is a broad range of estimated costs and currently officials are looking at allocating $52-55 million a year over a period from 2008 to 2028. We are trying to find short term solutions to congestion in the Valley. Ms. McGovern felt that if Council wanted to get public acceptance of these solutions, it needs to assure the public that there is a regionally accepted model that all cities are using together. She felt if there was not a common model, it would be difficult to reach agreement on how to spend $50 million. She asked if there was a plan to get other cities to accept the model? Mr. Knowles said it is a step by step process. However, none of the consultants question the results; they are more interested in what the results are. Mayor Pico indicated that one of the things under discussion when considering how to spend Prop 42 money is whether to allocate a portion of that to establish a comprehensive new model that incorporates all the traffic models. He felt they were moving rapidly toward a regional consensus. Pleasanton City Council Special Meeting Minutes 3 08/22/02
