LA River Low Flow Diversion (Compton Creek, LFD#1)


Project Location

The LA River Low Flow Diversion (Compton Creek, LFD#1) Project plans to divert dry weather runoff from the stormwater outfall Los Angeles Compton Creek (LACC) 155 near Main St and 107th St in Council District 8. The project will divert maximum dry-weather flow from a drainage area of approximately 2,732 acres.

Project Description

The Project, led by the City of Los Angeles Sanitation and Environment, is part of the Safe Clean Water Municipal Program. The LACC 155 Compton Creek stormwater outfall was deemed as a priority outfall in the Load Reduction Strategy document for dry weather bacteria discharges for Compton Creek developed by the Upper LA River Enhanced Watershed Management Group and the Cleaner Rivers through Stakeholder-led TMDL (CREST) group. Priority outfalls have consistent high bacteria loading that drive the storm drain loading rates above the Waste Load Allocation according to the monitoring-data-backed model developed from the study.

Project Goals and Benefits

The Project will:

  • Minimize or eliminate the discharge of potentially polluted dry weather runoff from the receiving waters;
  • Divert dry weather runoff in the stormwater collection system to the wastewater collection system to be conveyed to HWRP for treatment and reuse;
  • Improve health of local watersheds;
  • Improve health of marine life and of health of people that use beaches; and
  • Improve local water supply reliability.

Project Funding

The project is funded by the Los Angeles County Safe Clean Water Program.
