BUILDING AND SAFETY DIVISION- DRAINAGE & GRADING SECTION STANDARD URBAN STORMWATER MITIGATION PLAN (SUSMP) REVIEW SHEET

Urban and storm water runoff is considered to be one of the largest sources of pollution to both local waterways and coastal areas of the United States. Los Angeles County was issued a National Pollutant Discharge Elimination System permit for municipal stormwater and urban runoff discharges within the County of Los Angeles on December 13, 2001, by the Los Angeles Regional Water Quality Control Board. Under this permit, the County is required to prohibit the discharge of pollutants from private property developments. Preventing these pollutants from entering stormwater discharge system will be accomplished by requiring the installation and maintenance of post-construction treatment control Best Management Practices (BMPs) on qualifying projects
