Document Description
The proposed project would install a diversion structure that would divert storm drain flows from priority outfall LACC-155 (Reinforced Concrete Box [RCB] Junction of Los Angeles County Flood Control District [LACFCD] No. 635 and LABOE No. 19034) and outfall LACC-154 (California Department of Transportation 51-inch Reinforced Concrete Pipe [RCP]) to the sanitary sewer system during dry weather. Without the proposed project, the flow would otherwise discharge to Compton Creek in the City of Los Angeles. Project beneficiaries include community and stakeholder members, such as the Clean Rivers through Effective Stakeholders Total Maximum Daily Loads (TMDLs) (CREST) and the Upper Los Angeles River Enhanced Watershed Management Program, as the proposed project will improve water quality of Compton Creek and the Los Angeles River downstream from the diversion structure improving beneficial uses of the receiving water bodies.
