Healthy Watershed. Healthy Economy.


Industrial Stormwater

The Stormwater Community of Interest (SCOI) is a collaborative group focused on improving water quality in the Puyallup Watershed by rethinking how our communities approach stormwater management. The SCOI partners include individuals from a diverse group of organizations, businesses, and agencies located in the Puyallup River Watershed and the City of Tacoma. We have recently expanded the focus of our work so that we can include more stakeholders and approach stormwater issues from more angles.

The SCOI provides education and assistance to local businesses to support their work on mitigating environmental impacts and help share stories of their hard work and environmental victories with the public. We don’t enforce regulations; we work with businesses to help them comply with stormwater requirements and permits. We have also recently begun working with residents and community groups to find new ways to support positive change throughout the watershed in the ways that matter most to those who call the Puyallup Watershed home.
