Mitigation area through the years
Until the late 1800s, the shores along Steamboat Slough had an estuarine habitat where the fresh water mixed with the saltwater of Puget Sound and provided excellent habitat for salmon and other marine life. In the 1950s and ’60s fill was put on this site to build the northbound lanes of SR 529, then I-5. This buried the original habitat. Now WSDOT is restoring the land to its natural state, providing an additional 12 acres of habitat for salmon and other wildlife. This restoration project will mitigate another WSDOT project that requires about 2.5 acres of marshland to build a new off-ramp from northbound I-5 to northbound SR 529, and from southbound SR 529 to southbound I-5.
