What We Do


Improve ecosystem health in Pierce County by managing stormwater systems, monitoring watersheds and building partnerships.

Water Quality Monitoring: Monitor water quality, groundwater levels, stream flows and biology at more than 65 sites throughout Pierce County. This leads us to better understand the threats to local waterways and ways we can improve them. Monitoring some local waterways is required by state law. 

Technical Assistance for Stormwater Systems: Inspect more than 2,200 publicly and privately owned stormwater facilities per year and provide technical assistance for businesses.

Stormwater Pollution Inspection and Troubleshooting: Respond to, investigate and facilitate clean-up of pollution in stormwater systems and local waterways.

Municipal Stormwater Permit: Responsible for reporting, coordinating and administering the National Pollutant Discharge Elimination System (NPDES) permit for Pierce County.

Regional Coordination: Participation in regional boards and other groups related to recovery of Puget Sound and connected waterways.

Shellfish Protection: Conduct shellfish beach sampling and coordinate with the Tacoma-Pierce County Health Department and other partners on programs to keep pollutants out of shellfish beds.

Watershed Councils: Provide staff support and participate on four watershed councils: Nisqually River Council, Puyallup River Watershed Council, Chambers-Clover Watershed Council and Key Peninsula-Gig Harbor-Islands Watershed Council.

Salmon Recovery: Administer the Salmon Recovery Lead Entity funding for WRIA 10/12 and participate in salmon recovery efforts locally and regionally.
