Document Description
The project would consist of the construction of: a 2.1-million gallon capacity equalization basin, two diversion structures to passively divert excess flows from the existing Linda Mar and Arguello sanitary sewer lines and transport the flow via a conveyance pipeline to the EQ basin during storm events, an effluent conveyance pipeline routing flows to the existing Crespi Drive sanitary sewer line and Linda Mar Blvd. pump station, a 10-foot tall motor control center building that is equipped with a 4-ft high metal antenna that would allow radio communication with the city's Calera Waste Water Treatment Plant and the Linda Mar Pump Station, a ventilation and odor-control system, and a potable-water supplied cleaning system within the EQ basin. The EQ basin would be located within the parking lot for the city of Pacifica's Skatepark located at 540 Crespi Drive.
