San Gabriel River Coastal Basin Spreading Grounds Pump Station and Pipeline Project
MND - Mitigated Negative Declaration
Present Land Use
Los Angeles County Spreading Grounds and Collector Roadway
The proposed project would install approximately 6,000 linear feet of 78-inch rubber-gasketed reinforced concrete pipe between the Rio Hondo Coastal Basin Spreading Grounds (RHCBSG) and the San Gabriel Coastal Basin Spreading Grounds (SGCBSG). The pipeline would be installed beneath Mines Avenue and would include one concrete outlet structure at each Basin 2 of the Rio Hondo and San Gabriel Coastal Basin Spreading Grounds (SGCBSG) and three variable speed pumps and a sump in the cement-line canal at SGCBSG. The entire system would be linked through a telemetry system in order to ensure the proper operation of the gates when the pump is active.
