Spokane Regional Stormwater Manual
About the Manual
The Spokane Regional Stormwater Manual (hereinafter called “SRSM”) establishes standards for stormwater design and management to protect water quality, natural drainage systems and down-gradient properties as urban development occurs. The purpose of the SRSM is to help communities in the Spokane region to protect water quality, prevent adverse impacts from flooding, and control stormwater runoff to levels equivalent to those that occurred prior to development.
This section will outline the basic requirements that an owner or project developer must follow in order to be in compliance with the SRSM.
