The Public Works Department's - Environmental Programs and Operations Division manages the urban runoff and stormwater permit (MS4) for the City of Culver City.
The City is required to comply with the Municipal Separate Storm Sewer System (MS4) permit issued by the Los Angeles Regional Water Quality Control Board (LA RWQCB). The MS4 permit requires the City to implement Best Management Practices (BMPs) that would improve water quality in the Ballona Creek Watershed. The City joined the Ballona Creek Watershed Management Group (BC WMG) along with the cities of Beverly Hills, Inglewood, Los Angeles, Santa Monica, West Hollywood, and unincorporated areas of Los Angeles County.
To meet water quality requirements, the BC WMG drafted the Ballona Creek Enhanced Watershed Management Program (BC-EWMP) which addresses water quality issues by implementing institutional and infrastructure BMPs such as green streets and regional projects. Green streets and regional projects are designed to capture and treat runoff from all drainage areas in the Ballona Creek Watershed. To be in compliance, all agencies, including the City of Culver City, are required to manage runoff volume by implementing green streets or centralized regional projects.
The City will need to manage an equivalent volume of 99 acre-feet of runoff per storm event to meet water quality goals per BC-EWMP. The following is the recommended breakdown to achieve compliance:
- 62 ac-ft. from Regional Projects
- 20 ac-ft. from Green Streets
- 17 ac-ft. from Low Impact Development Projects
Based on planning estimates from the BC- EWMP, the City will need to invest approximately $140 million in implementation of capital stormwater projects to meet water quality compliance. Understanding the magnitude of compliance, on November 8, 2016, Culver City residents approved Measure CW, the Clean Water, Clean Beach Parcel Tax. The Measure established a dedicated fund source to improve water quality in Ballona Creek, Marina del Rey, Santa Monica Bay, and the Pacific Ocean.
The latest MS4 Permit was adopted by the Los Angeles Regional Water Quality Control Board on November 8, 2012, and became effective December 28, 2012. In addition to the LACFCD and County, the Permit is also issued to 84 municipalities within the County (the cities of Palmdale, Lancaster, Avalon, and Long Beach are excluded). Each Permittee is responsible for implementing its own stormwater program.
The new MS4 Permit presents major challenges including extensive monitoring requirements and the incorporation of 33 Total Maximum Daily Load regulations (learn more about TMDLs).
The new MS4 Permit also represents a shift in the way stormwater is regulated in the region. For the first time, a stormwater permit provides Permittees with incentives for integrated water planning. By combining water supply and water quality planning, Permittees can attract funding partners to build projects with multiple benefits. This new approach and look forward to working with stakeholders and partners to find, plan, and build exciting projects in the coming years.

Marina Del Rey
Construction to begin in summer 2019. For information on street closures during construction download our informational flyer.
Pursuant to the California Environmental Quality Act (CEQA) guidelines, an Initial Study (IS) determined that the project will not have a significant adverse impact on the environment with mitigation incorporation. A Mitigated Negative Declaration (MND) finding is adequate. The copy of the (IS/MND) and other documents are available at: City Hall, Engineering Division, Second Floor, 9770 Culver Blvd., Culver City, CA 90232 and at the Culver City Julian Dixon Library, 4975 Overland Ave., Culver City, CA 90230.

The Culver Boulevard Realignment Project is the continuation of the widening of Culver Boulevard that was completed by Caltrans as part of the 405 Freeway widening in 2009. This project will resolve traffic issues along this stretch of Culver Boulevard; and provide for a safer and more aesthetically pleasing street. The eastbound and westbound lanes of traffic is proposed to be separated with a new raised median.

Stormwater Quality Master Plan
The objective of the Master Plan is to develop a short-term (5 year) and long-term (10 year) planning tool that will identify potential Regional Projects, Green Streets Projects, and Low Impact Development Projects to collectively meet the City’s water quality compliance goals. The Master Plan shall incorporate factors in the BMP selection such as, but not limited to, City’s planned projects, Los Angeles Region Imagery Acquisition Consortium (LARIAC) to generate planimetric data, land use, hydrology, historical high groundwater levels, storm drain and sanitary sewer systems, in considering opportunities of potential projects. The Master Plan shall include for each project: cost estimates, summary pollutant reduction per project and BMP alternatives.
The City is proposing a dry weather diversion project that will capture low flow run-off from the Centinela Creek Channel (channel) by way of at grade trench drain into the City’s Mesmer Sewer Pump Station.
