Project description

King County is currently evaluating methods to reduce overflows from 5 combined sewer outfalls (shown on the map below) in accordance with Washington State law and the federal consent decree. These methods may include storage, treatment, or conveyance and will result in a variety of future projects.

During the planning phase, the project team will recommend an approach to control CSOs that considers a number of factors including regulatory, cost, environmental, and community priorities. King County’s regulators will review and approve plans before the projects move into design and construction.

We anticipate planning to end in fall 2025, with design and construction of projects associated with the Mouth of Duwamish Wet Weather Facilities to immediately follow.

 

The five King County outfalls included in this planning process are located in the east and west waterways of the Duwamish River on both sides of Harbor Island and along the shoreline of Elliott Bay generally in SODO.

King County is seeking to understand the feasible options to control pollution from these outfalls and meet regulatory and environmental requirements.
