Document Description
The South Coast Water District, per it’s 2017 Master Plan, proposes pipeline improvements for approximately 2,000 linear feet of 6-inch and 8-inch water main near the Mission Hospital that is unable to provide the required 4,000 gallons per minute (gpm) of fire flow at a 20 pressure-per-square-inch (psi) residual pressure. The Project involves replacing 1,350 linear feet of 8-inch asbestos cement pipe (ACP) water main with 12-inch polyvinyl chloride (PVC) pipe, replacing 160 linear feet of 6-inch ACP water main with 12-inch PVC pipe, installing valves and valve clusters as required, and reconnecting service connections and fire hydrants as required. The pipeline alignment runs south along Mar Vista Avenue from 3rd Avenue to Sunset Avenue, south along Sunset Avenue to 8th Avenue, and also down a hill from Sunset Avenue to Mission Hospital. This Project is a part of the SCWD’s modified Capital Improvement Plan (CIP) to replace aging infrastructure and meet fire flow requirements to support wildfire mitigation efforts and increase fire water supply within the District’s 490 pressure zone located to the east of Pacific Coast Highway in the northern part of the District.
