The Seattle Department of Transportation (SDOT) today announced the selection of a multi-disciplinary team led by Tetra Tech .

The firm has extensive experience with delivering multi-disciplinary design efforts, enhancing marine habitats, preparing environmental documentation and providing permit support for large, complex projects involving land and water. The city’s interview panel, which included representatives from SDOT, the Seattle Design Commission and several other city departments, ranked Tetra Tech as the top firm of four teams interviewed.

Built between 1916 and 1934, the seawall runs along Elliott Bay in downtown Seattle from South Washington St to Broad St. Tetra Tech will be responsible for assisting the city of Seattle in replacing the central portion from S Washington St to Pine St, which is anticipated to cost $285 million. SDOT is seeking to replace the seawall with a long-term solution that meets seismic standards, improves habitat, and provides effective protection for the public, waterfront facilities and economic activities.
