5. Identify available fuming and timelines; 6. Report results and recommend optimum project scopes and sequencing. The first key element listed above has been discussed at several recent TAC meetings. The TAC has agreed to recommend using the newly developed Contra Costa Transportation Authority's (CCTA) travel demand and forecasting model with the following additional ref'mements: · Refine Tri-Valley land use to be consistent with each City's General Plans. The current land use is based on ABAG projections (2003) and still includes development in North Livermore, and excludes some east Dublin development. · Refine the roadway network to add Tri-Valley arterials and other significant roadways. · Update and refine the way the model treats traffic from San Joaquin County. · Add capacity constraints/peak spreading to the model at key gateways to the Tri- Valley. · Recalibrate the model after making the above adjustments. These recommendations were presented to the study's PAC, consist'rog of Tri-Valley Mayors/Councilmembers and CMA Board representatives, on January 31, 2005. The cost of making these refinements to the CCTA travel demand and forecasting model exceeds the CMA's budget by about $50,000. The second key element listed above has also been discussed by the TAC. There are two options emerging as a potential traffic operations model to use for this study. However, the TAC needs additional time and effort to fully explore the costs and benefits of the two alternatives before making a recommendation. Each of the alternatives will exceed the CMA's budget by an amount ranging from $20,000 to $125,000. Thus, the total cost of the study is expected to exceed the CMA's budget by an amount ranging from $70,000 to $175,000. In addition, the study budget only assumes the analysis of up to eight combinations of roadway network alternatives. Additional funds will be required if more than eight alternatives are desired. The consultant has been asked to provide a cost for adding additional alternative analysis. The CMA has asked each of the Tri-Valley cities to sign a letter of intent to fund these additional costs. The Consultants will be given a notice to proceed once the CMA receives the letters of intent. The share of the additional costs would be split between Pleasanton, Livermore and Dublin based on a future discussion among the three cities, and may not be split equally. The level of effort to refine the travel demand and forecast'mg model will not be equal for each city. Pleasanton's new traffic model already includes more local detail than the SR 05:050 Page 3 of 5
