Stormwater Management Program
The Yuba County Storm Water Management Plan (SWMP) is being initiated by Yuba County and the City of Marysville to fulfill requirements of the National Pollutant Discharge Elimination System (NPDES) Phase II requirements for Small Municipal Separate Storm Sewer Systems (Small MS4s).  The Yuba County SWMP provides a plan for the affected agencies within the County to follow Best Management Practices (BMPs), measurable goals, and timetables for the implementation of the Six Minimum Control Measures required by the United States Environmental Protection Agency, and the State Water Resource Control Board.
