The Spokane Regional Stormwater Management Manual (SRSM) applies to development projects and establishes design standards for stormwater design and management to protect water quality, natural drainage systems, and down-gradient properties. The SRSM was jointly developed by Spokane County, the City of Spokane Valley and the City of Spokane.
