Former Stillaguamish Clean Water District

SWM District Consolidation

Effective July 21, 2017, Snohomish County consolidated the Stillaguamish River Clean Water District (CWD) with the Snohomish and South County Watershed Management Areas (WMAs) into one county-wide Surface Water Management (SWM) Utility District. For more information about this change, see the SWM consolidation ordinance (17-020) (PDF).

Snohomish County Council’s approval of the SWM consolidation ordinance repealed Title 25A of the Snohomish County Code and dissolved the CWD Advisory Board. However, the county will continue to provide staff support for CWD Advisory Board meetings through the end of 2017. While the Advisory Board no longer has an official role, SWM is seeking the Advisory Board’s input as we transition to the new county-wide SWM Utility District. The Advisory Board’s knowledge and experience will help shape new county-wide policies and services, including the new small grants program that will replace the CWD Discretionary Fund and expansion of shellfish protection to the Snohomish and South County areas. This important work will guide SWM priorities and investments for the next five to ten years.


In 1993, the Snohomish County Council created the Stillaguamish River Clean Water District (CWD) to “provide a comprehensive approach to managing and regulating surface water in order to respect and preserve the county’s rivers, streams, lakes, and other waterbodies” (Snohomish County Code Title 25A.05). Here's how it worked:

  • Landowners within the former CWD paid annual fees that have enabled the county to provide water quality and water quantity management services in the Stillaguamish River Basin.
  • The Clean Water District Advisory Board, comprised of CWD ratepayers, agencies, and businesses, was created to guide the spending of CWD revenues. The advisory board has provided recommendations to the County and partner organizations working on water quality, water quantity, and aquatic habitat issues within the Stillaguamish River watershed.
  • Snohomish County has used CWD revenues to provide numerous surface water services to landowners within the CWD. These public services have included: technical and financial assistance to landowners, shellfish protection, water quality monitoring and pollution control, drainage and flooding assistance, and salmon recovery projects.
