BMP Performance Report Library

What are best management practices?

Stormwater comes from rain or melting snow that does not soak into the ground. As it flows, stormwater runoff collects and transports potential pollutants that can harm our rivers, streams, lakes, and coastal waters.

To protect these resources, communities, construction companies, industries, and others, use stormwater controls, known as best management practices (BMPs). These BMPs filter out pollutants and/or prevent pollution by controlling it at its source.

Purpose of this library

As a supplement to the Riverside County BMP Design Handbook, this BMP Performance Report Library is provided as a reference for Permittees in their review and approval of  Water Quality Management Plans (WQMPs).


This BMP Performance Library includes references to independent third party reports/studies on the measured and/or anticipated performance of various proprietary and non-proprietary BMPs at reducing or eliminating the discharge of pollutants associated with urban runoff and stormwater. 

The identification of particular manufacturers, consultants, products, or services in the referenced reports in no way represents endorsement or guarantees acceptance by the District or the Permittees. Each Permittee has the discretion to determine which BMPs may be evaluated and are accepted on a case by case basis. The phrase “Best Management Practice” is a common term used in Federal, State, and local regulations to label these types of products. For any proprietary BMPs, please contact the product manufacturer and follow the manufacturers’ specifications for preparation, installation, and maintenance of their products.

This library will be updated/verified periodically.
