Map showing the three reaches of the Lower Duwamish Waterway Superfund Site

The Lower Duwamish Waterway Superfund site is divided into three reaches: upper, middle, and lower reach. The middle reach is a 1.4‑mile stretch of the waterway between Duwamish Waterway Park and about a quarter mile north of the 1st Avenue South Bridge (see yellow section on map).

Cleanup construction in the middle reach is expected to begin as soon as fall 2028 and continue each fall and winter for at least six years.

LDWG is still early in the process of designing the specific details of middle reach cleanup construction. We will make details of construction activities available to the public as soon as plans are final. See our website to learn more about what you can generally expect during construction.
