Welcome to Snohomish County Public Works

Public Works is the largest department in Snohomish County and responsible for many services that affect residents’ lives on a daily basis.

Those services are divided into three main categories:
  • Roads: Developing and maintaining roads, bridges, traffic, and the general transportation system within unincorporated Snohomish County. 
  • Solid Waste: Overseeing the disposal of solid waste (trash and recycling) within all of Snohomish County.
  • Surface Water: Managing and monitoring surface water including storm water drainage and flooding, as well as water quality in rivers, streams, lakes, and aquatic habitat.

The mission of the department is to enhance the quality of life for present and future generations.

The department is committed to serving all residents by adhering to the Title VI section of the Federal Civil Rights Act of 1964 and the Americans with Disability Act. Visit the Public Works ADA page for more information.
