Donald C. Tillman Water Reclamation Plant Japanese Garden Discharge Reuse Project

Pursuant to the State of California Public Resources Code Article 7 of the California Environmental Quality Act (CEQA), as amended, the City of Los Angeles, Department of Public Works, Los Angeles Sanitation and Environment has prepared an Initial Study (IS) for the project described below. Under CEQA, the City identified no significant impacts and proposes to adopt a Negative Declaration (ND).

PROJECT LOCATION: The proposed project is located at the Japanese Gardens area of the Donald C. Tillman Water Reclamation Plant, located at 6100 Woodley Ave in the Sepulveda Basin within the City of Los Angeles (City).

PROJECT DESCRIPTION: The City, acting by and through the Department of Public Works, Los Angeles Sanitation and Environment (LASAN), and the Los Angeles Department of Water and Power (LADWP), intends to change the place of use and purpose of use of up to 4,820 acre-feet per year (AFY) of recycled water (Subject Recycled Water) from the Donald C. Tillman Water Reclamation Plant (DCTWRP) (the Project). This Initial Study (IS) has been prepared to evaluate the potential environmental impacts of the City’s proposed Project and seek authorization from the State Water Resources Control Board (SWRCB) to proceed. LADWP is the City department responsible for managing and controlling all of the City’s water rights. LASAN is the owner and operator of the DCTWRP.

Currently, the Subject Recycled Water from the DCTWRP is discharged into the Japanese Garden Lake and then into the Los Angeles River, immediately downstream of the Sepulveda Dam. The predominant source of the Subject Recycled Water is imported water from the State Water Project and the Los Angeles Aqueduct System. The City intends to seek authorization from the SWRCB for LASAN to recirculate recycled water in the Japanese Garden Lake back to DCTWRP, and to provide the Subject Recycled Water to LADWP to recharge the San Fernando Groundwater Basin (SFB) to enhance local water supplies. If authorized, the City’s repurposing of the Subject Recycled Water would result in decreased discharges into the Los Angeles River.

: The Draft IS/ND for the Project will be circulated for a forty-five (45) day public review period, beginning on December 14, 2021, and ending on January 28, 2022. Copies of the document are available for review at the following locations:
