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.


  1. Draft 2023 Program Goals
  2. Proposed 2023 Budget

Each year, Spokane County publishes a Stormwater Management Program 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.

Below is a preliminary draft of the program goals specific to the calendar year 2023.  It does not include routine operations, such as spill response or drywell inspections and cleaning, but instead highlights featured programs or project targets.   Greater details about the County’s Stormwater Management Program may be found in the current Plan, published in March 2022, which can be accessed on the Stormwater Utility section of the Public Works page of the Spokane County website: Water Quality and Permits | Spokane County, WA
