The American River Basin (ARB) Stormwater Resource Plan (SWRP)
Maureen Kerner, P.E. Office of Water Programs California State University, Sacramento
What is a SWRP? • Manages runoff on a watershed scale ▫ Stormwater and dry weather runoff
• Required by Water Code §10563 /Senate Bill 985 ▫ Required to receive grants ▫ Incentive to use runoff as a resource to: Improve water quality Reduce localized flooding Increase water supplies for beneficial uses
• A Living Document ▫ An ongoing, adaptive program ▫ Methods to identify, plan, & implement projects
SWRP Requirements • Incorporate into IRWMP • Define Watershed(s) • Describe Stakeholder Involvement • Address Water Quality Compliance • Quantify (Multiple) Benefits ▫ Water Quality ▫ Water Supply ▫ Flood Management ▫ Environmental ▫ Community
• Identify and Prioritize Projects • Describe Implementation
