Water Quality Management Plans


WQMPs are required for many construction and redevelopment projects. A WQMP describes all post-construction activities and Best Management Practices (BMPs) implemented to reduce stormwater pollution as required by the Santa Ana Regional Water Quality Control Board.

The following attachments can be used to describe why a WQMP is necessary, determine the priority of the project and also view the template for submittal.

  • City of Buena Park WQMP Screening Checklist: Provides a description of what a WQMP is, why one is required and what items to include in a submittal. The check list that City Plan Checkers use to determine WQMP approval is also included.

Please call the Public Works Department, Stormwater Division at (714) 562-3655 should you have any questions regarding submittals.


Priority Project Preliminary Water Quality Management Plan

A Preliminary Water Quality Management Plan (link is above) is required at the earliest phase of planning for new development and significant redevelopment projects that require approval by the Zoning, Planning Commission, or City Council. Applicants are required to submit the Preliminary WQMP for approval by the City prior to the Planning Commission hearing . For private developments that do not require discretionary approval by the Planning Commission or City Council, developers are also required to submit a Preliminary WQMP.
