Site work for a civil project in Boulder Creek, California. Conceptual plans call for site work for a water / sewer project.

The Department of Water Resources Urban Community Drought Relief (DWR) Water Storage Tanks Replacement Project includes the design of five tank sites to replace existing tanks and design of a new pump station at one of the tank sites for the San Lorenzo Valley Water District (SLVWD) system. The District's intent is to enter into a single design agreement to an engineering firm qualified to prepare the required design plans, details, and specifications; for construction of the project to be bid as three separate packages. The District proposes to construct five new potable water storage tanks with usable 120,000- gallon water storage to replace existing tanks that are undersized, leaking and extremely vulnerable to wildfire at five District sites. The Consultant shall evaluate each site to determine if the increased tank capacity is feasible, and shall coordinate any change in proposed tank volume with the District. The project will generally include design of site improvements for construction of the new tank, design of a new SCADA system to integrate with the existing District SCADA system, design of a new pump station and all required piping and appurtenances necessary to connect proposed facilities to the existing District facilities. The District anticipates the prefabricated tank design will be provided by the tank manufacturer as a deferred submittal by the Contractor meeting the design requirements specified in the contract documents. The scope of tank design generally includes: tank dimensional sizing, to include seismic analysis and slosh volume; geotechnical analysis of tank sites; foundation or footing design; tank design requirements, to include access, venting, and mixing system design; yard piping and valving design; tank site layout; stormwater and erosion control design, both temporary for construction and permanent infrastructure. The scope of pump station design will be predicated on tank site elevations. At a minimum, the scope shall include analysis of required pump specifications; design of fire-hardened pump station; foundation or footing design; associated piping; vaults; valving; SCADA and electrical power connections. Since the pump station is not financed with the DWR grant the costs for the design and construction of the pump station will need to be tracked separately for the project. All tanks, pumps, distribution mains, transmission mains, and services shall be designed in accordance with CA-DDW Waterworks Standards. All materials, appurtenances, installation and testing procedures shall comply with ASTM and/or AWWA standards, as well as the SLVWD's water system construction standards. All designed work to be in conformance with District, County, State, and AWWA requirements.
