Help shape the look and feel of clean water facilities in SODO!

King County has proposed clean water facilities to reduce combined sewer overflows (CSOs) at five outfall locations at the mouth of the Duwamish River. These facilities will help control the stormwater and wastewater that is sometimes released into the Duwamish River during heavy storms. The proposed solution includes:

  • A new wet weather treatment station in SODO
  • A new storage tank in West Seattle (Industrial District West)
  • A new outfall for cleaned water
  • New pipes and supporting facilities to connect flows along the way

This survey will help inform the look and feel of the new wet weather treatment station in SODO. It will also help us understand how we may align project goals.

We’ll also offer opportunities in the future to give input on the West Seattle storage tank, in alignment with the schedule for that work.

What will happen with my feedback?

We consider all feedback and determine what makes sense for the project’s design.  Design decisions must balance many factors, including:

  • Cost
  • Schedule impacts
  • Long-term operations and maintenance
  • Environmental impacts
  • Community and social impacts

By the end of the year, we’ll share what we heard from the community and explain how that feedback shaped the look and feel of the new wet weather treatment station. If we receive feedback that we cannot use, we will explain why.

What happens next?

You can share your contact information at the end of the survey. If you do, we can reach you for future feedback opportunities. If you opt to not share your contact information, your input will remain anonymous.

We also plan to bring together a Community Sounding Board whose input will inform future design decisions.
