Document Description
The project is located on Los Coches Road between Via Diego and Ha Hana Road in the unincorporated community of Lakeside in San Diego County. An existing 30-inch reinforced concrete pipe (RCP) is located under Los Coches Road, which collects storm water runoff and discharges into a reinforced concrete triple box (RCB) culvert at Los Coches Creek. During the dry season, runoff from irrigation and other urban sources flows into the 30-inch RCP without receiving water quality treatment. The proposed Los Coches Low Flow Urban Runoff Diversion to Sewer Project would capture and divert dry weather flows to an existing County sewer line using a gravity flow system allowing the runoff water to be treated. The goal of the project is to improve water quality by reducing the non-storm water flows from entering the municipal separate storm sewer system (MS4) within the County road right-of-way.
