Public engagement

Discover how King County is engaging the community around the West Duwamish Wet Weather Storage Facility, from public art to community meetings and events.

Our commitment to our local communities

Through this project, our team will seek opportunities to support community-driven initiatives in the nearby neighborhoods. After talking to community leaders and partners, we have identified some high priority neighborhood goals around water quality, river and community connections, and economic support. We will continue to engage community members to help us refine the opportunities for community benefits.

The storage facility and surrounding site will incorporate many sustainable elements. Some examples of design elements already added include new trees, solar panels, and rain gardens. Visit our recent online open houses to learn more:

We know that many South Park residents are excited about raingardens and other “green” solutions to keep polluted runoff or storm water out of the Duwamish. The RainWise program provides rebates that cover up to 100% of the cost of installing rain gardens and cisterns that will help manage runoff.

King County’s commitment to sustainability and Equity and Social Justice

King County has prioritized sustainable development and practices that support Equity and Social Justice (ESJ).

  • The County’s sustainability program provides a green building guide for infrastructure projects. On this project, we’ll look for sustainability opportunities at the storage tank site and in the South Park neighborhood. 
  • King County promotes Equity and Social Justice in design, construction and management of infrastructure projects so communities can thrive. This means we are committed to taking feedback from the community, and you can expect to see us working with community groups in the project area to ensure that the project reflects neighborhood values.
