The Los Angeles County Municipal Stormwater National Pollutant Discharge
Elimination System (NPDES) Permit contains a requirement for Permittees
to develop and implement programs for stormwater management within the
County of Los Angeles. The Model Programs
provide guidance that Permittees can follow to implement their own
programs in compliance with the Permit.
One specific requirement from the Development Planning Model Program is
to develop a Standard Urban Storm Water
Mitigation Plan (SUSMP). The SUSMP serves as a model guidance
document for use by builders, land developers, engineers, planners, and
others in selecting post-construction Best Management Practices (BMPs)
and in obtaining municipal approval for the urban storm water runoff
mitigation plan for a designated project prior to the issuing of building
and grading permits.
Water Quality Reports and Data: The Stormwater
Quality Monitoring Reports provide status of implementation and results
of the monitoring program as required under the NPDES municipal stormwater
permit. You can download/view Stormwater Quality
Summary Data that represent land use distribution, hydrologic information,
bacteria counts, EMCs, pollutant loading, water quality statistics, etc.
