Water Quality Management Plan

Water Quality Requirements for Development Projects (WQMP)

To help you determine whether or not your project must comply with the current (2010) Permit and use the 2012 WQMP Template and Guidance Document, the following is provided:

  • If your project did not have an approved PRELIMINARY or FINAL WQMP on APRIL 22, 2013, according to section XII.E.1 of the Permit, all projects that meet the criteria of Table 1-1 that are not Pre-Approved, are required to prepare a Project-Specific WQMP that fully meets the requirements of the 2012 WQMP Guidance Document.

The City's Municipal Separate Storm Sewer System (MS4) National Pollutant Discharge Elimination System (NPDES) Permit, issued by the Santa Ana Regional Water Quality Control Program outlines the regulations and prescribes the programs that the City must implement in order to control pollution to the Maximum Extent Practicable (MEP).

Water quality requirements for specific "priority" development and redevelopment projects are detailed in the Riverside County Drainage Area Management Plan (DAMP).
