Stormwater Management

Riverside County Watershed Protection Program is a partnership between Riverside County, the Flood Control & Water Conservation District, Coachella Valley Water District and 27 cities that manage watershed programs which protect, preserve and enhance the quality of the water and the natural environment of our watersheds.

We manage three watersheds under separate MS4 Permits:

  1. Santa Ana MS4 Permit
  2. Santa Margarita River Regional MS4 Permit
  3. Whitewater River MS4 Permit

LID BMP Design Handbooks

The Design Handbooks for Low Impact Development Best Management Practices (LID BMP Design Handbooks) were developed by the Riverside County Flood Control and Water Conservation District, for use on development projects in Riverside County, as a supplement to be used in conjunction with the Riverside County Water Quality Management Plans (WQMPs). 

Water Conservation Tracking Tool

This useful tool (also known as the “Geodatabase”) was created to support stormwater management tracking and decision making by the MS4 Copermittees. It is also useful to Developers, Planners, Engineers, Utility Companies and other businesses and can be used to help guide you through the development process.

Municipal Training

Municipal training information as required by our National Pollutant Discharge Elimination System (NPDES) Permits.
