Mitigation Bank Project Sites

—Credits available mid-2022—

The Duwamish River People’s Park and Shoreline (formerly known as Terminal 117) is the first habitat project built as part of the mitigation bank that will allow third parties to invest in Port habitat projects via purchase of mitigation credits.

The project is restoring 14 acres of habitat, includes forested buffer, emergent marsh, mudflat, shallow subtidal, and deep subtidal areas along nearly half a mile of Duwamish River shoreline. The restoration creates valuable off-channel habitat in the marine-freshwater transition zone, enhancing a high-priority migratory corridor for Chinook salmon. In this habitat, out-migrating juveniles can seek refuge while acclimating to saltwater environments before navigating into Puget Sound.
