Stormwater Best Management Practice (BMP) Handbooks The California Stormwater Best Management Practice Handbooks have provided excellent guidance to the stormwater community since their publication by the Stormwater Quality Task Force (SWQTF) in 1993. The SWQTF became the California Stormwater Quality Association (CASQA) in 2002 and in 2003 CASQA published an updated and expanded set of four BMP Handbooks. These Handbooks reflect the current practices, standards, and significant amount of knowledge gained since the early 90s about the effectiveness of BMPs. For additional information, please visit the CASQA website.   Click on the links below to view and download the individual handbooks. This website has been updated for access to the 2004 Errata of the Handbooks.

The California Stormwater Quality Association (CASQA) is an independent advisory group. The statements, views, and contents of this site do not necessarily reflect those of the State Water Resources Control Board or the Regional Water Quality Control Boards.
