Our Services to You


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 two 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.
Note: Surface Water Management is now a division of the county's new Conservation and Natural Resources department.

The public can conduct all business by phone or through email. Staff will respond as promptly as possible, 8 a.m. to 5 p.m., Monday through Friday. Our Customer Service Center is open for in-person services from 8 a.m. to 3:30 p.m., Monday through Friday.
