This project is a comprehensive restoration program for the entire Green/Duwamish ecosystem spanning the tidal estuaries to the spawning and wildlife habitat areas in the upper basin. Congress authorized 45 separate project elements located that emphasize the restoration of critical habitat within the Green/Duwamish River watershed. Several anadromous fisheries stocks and wildlife species are threatened or are listed endangered, significantly affecting the Puget Sound watershed.
The project was authorized in the Water Resources Development Act of 2000. Total implementation cost is currently estimated to be $292 million, cost shared 65% federal, 35% non-federal. This project has the full support of King County, the cities in the basin, Muckleshoot and Suquamish Indian Tribes, the Washington State Department of Fish and Wildlife, the U.S. Fish and Wildlife Service, Trout Unlimited, as well as numerous other local resource agencies.
