Pursuant to the State of California Public Resources Code (PRC) Article 7 of the California Environmental Quality Act (CEQA), as amended, the City of Los Angeles, Department of Public Works, Bureau of Sanitation and Environment (LASAN) and the Bureau of Engineering (BOE) has prepared a Final Environmental Impact Report (Final EIR) for the project described below. The City of Los Angeles is the Lead Agency under CEQA.

PROJECT LOCATION: The proposed project would occur within the southeastern area of MacArthur Park and in the public right-of-way on adjacent streets southwest of the park. MacArthur Park is a public park located at 2230 W. 6th Street in the Westlake neighborhood of central Los Angeles, approximately 1 mile northwest of downtown.

PROJECT DESCRIPTION: The proposed project, led by LASAN in partnership with the BOE and the Department of Recreation and Parks (RAP), would implement a regional multi-benefit stormwater project in MacArthur Park as part of the region’s efforts under Los Angeles County’s Safe Clean Water Program (SCWP) to meet water quality total maximum daily load (TMDL) limits for the Ballona Creek watershed and the current National Pollutant Discharge Elimination System (NPDES) permit. The proposed project would divert and treat portions of wet weather stormwater flows as well as dry weather flows from the existing underground storm drain system and discharge it into MacArthur Lake for storage or return it to the storm drain system. Some of the water stored in the lake would subsequently be discharged to the sanitary sewer.

Aboveground features of the project would consist of a new water feature near the southwest corner of the park and some equipment within and/or adjacent to an existing pump house located south of the lake. The underground diversion, capture, and pretreatment structures would be located in Lake Street south of the park. An additional underground stormwater treatment unit would be located along the southern edge of the park. Underground pipelines would be located in the park and in Lake Street, Grand View Street, and 7th Street.

The proposed project would divert and treat portions of wet weather stormwater flows as well as dry weather flows from the existing underground storm drain system and discharge it into MacArthur Lake for storage or return it to the storm drain system. In-lake storage would decrease the use of potable water to maintain the lake water level. Some of the water that is stored in the lake would subsequently be discharged to the sanitary sewer system. The project would reduce the amount of stormwater and dry weather flows, and their associated pollutant loads, that enter Ballona Creek and, ultimately, Santa Monica Bay. Additionally, the proposed project would enhance the park by creating a water feature and providing educational opportunities, such as signage and information boards about stormwater management.

Final EIR Certification

The BOE intends to present the CEQA findings to the City of Los Angeles Department of Public Works Board of Commissioners (BPW) on TBD to seek project approval as describe in the Final EIR. The BPW meeting date will be updated to this webpage once the date is determined. The public can also check https://dpw.lacity.gov/board-public-works-meetings for updates on the BPW meeting date.

Following recommendations from the BPW, the BOE intends to present CEQA findings to the Los Angeles City Council on TBD to adopt and certify the Final EIR. The City Council meeting date will be updated to this webpage once the date is determined. The public can also check https://lacity.gov/government/calendar/city-council-meetings for updates on the City Council meeting date.
