Document Description
South Coast Water District, per it’s 2017 Infrastructure 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 gpm of fire flow at a 20-psi residual pressure. The Proposed Project involves replacing approximately 2,000 linear feet of 6-inch and 8-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. Project construction would consist of excavation, backfill, pipeline installation, and repaving. The pipelines along Mar Vista Avenue and Sunset Avenue would be installed a minimum of 40-inches below ground level and the pipeline that runs down a hill from Sunset Avenue to 5th Avenue would be installed at 24-inches below ground level. Streets affected by construction would be repaved to their pre-disturbance conditions.
