FOR THE VINEYARD HILLS RESERVOIR AND ACCESS ROAD, CIP NO. 011023-W.T. AND ABANDON THE CITY'S TEMPORARY CONSTRUCTION EASEMENT ON THE THREEHAND LP PROPERTY SUMMARY Construction of the subject project is complete and is ready for acceptance. The project consisted of constructing a new 1.4 million gallon concrete water tank (reservoir) partially buried in the hills just south of Old Vineyard Avenue to serve new development in the Vineyard Corridor Specific Plan (VCSP) area as well as enhancing water supply to the Bonde water zone. The project also included the "rough-grading" of an access road to the tank in order to provide adequate access to the site during construction of the tank. A temporary construction easement on the Threehand LP property required for the access road work is no longer needed and can now be abandoned. This project was part of the overall water facilities identified in the VCSP which also included improvements to the Zone 7 turnout, a new water booster pump station, water pipeline and appurtenant infrastructure facilities. RECOMMENDATION 1. Accept the improvements for the Vineyard Hills Reservoir and Rough Grading of the Access Road (CIP 011023). 2. Authorize the City Clerk to file a Notice of Completion for the subject project. 3. Authorize final payment to Gateway Pacific Contractors, Inc. in the amount of $758.36. 4. Authorize payment of the retention in the amount of $197,687.35 to Gateway Pacific Contractors, Inc. thirty days after recordation of the Notice of Completion. 5. Authorize the City Manager to execute and file a quitclaim deed abandoning the City's temporary construction easement on the Threehand LP property. FINANCIAL STATEMENT This project is part of the City's water supply infrastructure planned and approved as part of the Vineyard Corridor Specific Plan area. It is expected that operation of this facility will add minimal costs to the City's annual water enterprise operating expenses. Construction of the water tank included new landscaping and an irrigation system around the tank, which will require ongoing maintenance activities estimated to be approximately $3,000 annually. In addition, routine cleaning and maintenance of the cathodic protection for the tank is estimated to be approximately $2,000 annually.
