Monterey Regional Storm Water Management Program (MRSWMP)

The Monterey Regional Storm Water Management Program (MRSWMP) was developed by the cities of Carmel-by-the-Sea, Del Rey Oaks, Monterey, Seaside, Sand City, Marina, Pacific Grove and Monterey County as a joint effort to monitor and reduce storm water pollution. In order to promote water quality, a series of best management practices (BMPs) were designed to reduce the amount of storm water runoff and pollution that enters the region's storm drains and watercourses that ultimately lead to Monterey Bay and the Pacific Ocean.

Please note that the MRSWMP document was retired on June 30, 2013.

On July 1, 2013, the Phase II Small Municipal Separate Storm Sewer System (MS4) Permit became effective for small municipalities throughout the State with populations less than 100,000.  The new Permit generally updates the requirements of the MRSWMP document by defining measures that municipalities are expected to perform to minimize the pollutants that discharge with the stormwater that leaves their drainage systems (MS4s).  The State Water Resources Control Board is required to review and update the Municipal Stormwater Permit on a five-year cycle to respond to new technologies that make treating stormwater possible.
