Stormwater Utility

The Stormwater Utility, a section within the Public Works Department, ensures that stormwater systems are planned, developed and maintained to prevent flooding, protect water quality and preserve natural stormwater systems. The Stormwater Utility strives to provide leadership and a focus for other community efforts working toward improved stormwater management that causes as little short-term and long-term harm as possible to the environment.

2024 Draft Program Goals

Each year, Spokane County publishes a Stormwater Management Program Plan (Plan) that describes the programs and practices used by the County to operate and maintain the Municipal Separate Storm Sewer System (MS4), to operate and maintain municipal UICs (drywells), and to implement related Permit programs.  Spokane County’s Stormwater Management Program is designed to uphold the County’s long-term commitment to minimizing pollutants discharged to Waters of Washington State.

We would like to hear your thoughts and opinions about the draft program activities and goals for 2024, which are shared below.  Your feedback is invited through informal comments, which means that all input will be reviewed and given due consideration, but individual responses will not be provided at this time.  Thank you for your involvement in the task of stormwater management in Spokane County; your time and resources are valuable, and we appreciate you sharing them with us.
