Ballona Creek Bacteria TMDL Project

Ballona Creek Bacteria TMDL Project

The Ballona Creek Bacteria Total Maximum Daily Load (TMDL) Project is being proposed to meet water quality objectives established by the Los Angeles Regional Water Quality Control Board that address elevated bacteria levels and the water quality impairments of Ballona Creek and Estuary during dry weather.

The project proposes utilizing treatment and low-flow diversion technology at three existing locations along Ballona Creek, Sepulveda Channel and Centinela Creek where water treatment or water quality facilities are already in place.

This project will achieve compliance with TMDL water quality mandates, improve public health and the beneficial uses of Ballona Creek and Estuary, while providing a new source of water to offset potable water use by diverting a portion of the runoff to the Hyperion Water Reclamation Plant.

The County of Los Angeles and the cities of Los Angeles, Beverly Hills, Culver City, Inglewood and West Hollywood are partnering together on this project with the City of Los Angeles, LA Sanitation in the role as the lead agency.

A California Environmental Quality Act (CEQA) environmental review process is being conducted for this project with the City of Los Angeles, LA Sanitation preparing an Environmental Impact Report (EIR).

Interested agencies, organizations and parties may review the Draft EIR and other documents via the links provided below.


LA Sanitation released the Draft EIR on August 17, 2017 for public comment. The comment period concluded on October 16, 2017 and LA Sanitation is currently reviewing the public comments and amending the Draft EIR to produce a Final EIR. The Final EIR is anticipated for release at the end of 2017. LA Sanitation will notify stakeholders when the Final EIR is released.
