6. Approve the appropriation of $2,987,012 as detailed in Updated Draft Financing Plan for Vineyard Avenue Corridor Infrastructure Improvements (Updated Financing Plan) included as the companion report in this agenda. FINANCIAL STATEMENT Construction costs for these projects will be met as detailed in the Updated Financing Plan included as the companion report in this agenda. The operation of the new booster pump station and turnout will result in some additional staff operational, maintenance and energy costs. In addition, construction of these two facilities will add to the City's overall base cost used to determine replacement and improvement accrual charges for the entire City water system infrastructure. BACKGROUND When the VCSP was being developed in 1998-1999, City Public Works and Planning staff worked closely with the engineering consultants for the VCSP developers to determine the utility system needs (water, sewer and storm drainage) and projects necessary to serve the area. This effort resulted in the identification and preliminary design of a number of new water and sewer facilities in the area. All of these new utility improvement projects were needed since the existing utility systems on either side of the VCSP were either close to reaching, or had reached, their design capacities (as was the case for water facilities in the Ruby Hill and Vintage Hills areas), or were non- existent (as was the case of sewer facilities in the area). These preliminary designs formed the basis for the Public Facilities section of the VCSP. The new water facilities necessary to serve the VCSP area included improvements to an existing (but standby) Zone 7 turnout (a turnout is a large metering and valve vault used to control and meter water deliveries from the Zone 7 water transmission system into the City's transmission and distribution system), construction of a new water booster pumping station (to be located on the same site as the Livermore Pleasanton Fire Department Station No. 5), a new water storage reservoir located at an appropriate elevation and of an appropriate size within the VCSP area, and a new reservoir access road and pipeline to connect the reservoir to the new pump station, turnout and VCSP water infrastructure. All of these facilities, including the access road, need to be constructed in order to provide water to the developing VCSP area since the water facilities on either side of the area were unable to do so. That is, during the summer months, pumping stations on either side of the VCSP are overburdened, and have to use their spare or emergency pumps just to keep up with normal summer demands. This can lead to low water pressures, water service interruptions, and potentially inadequate water supply for the area. Sealed bids for the Turnout No. 6 Improvement Project were opened on October 17, 2006. Seven bids were received, with the low bid of $231,312 submitted by Gateway Pacific Contractors Inc. The Engineer's estimate for this project was $300,000. On November 30, 2006, sealed bids were opened for the Booster Pump Station. Seven bids were received, with the low bid of $1,785,700 submitted by JMB Construction, Inc. Page 2 of 6
