Elliott Bay Seawall Project

The Seattle Department of Transportation (SDOT) and the U.S. Army Corps of Engineers (USACE) are in the process of designing the alternative for replacing the Elliott Bay seawall along the Seattle Waterfront. The seawall runs along Elliott Bay in downtown Seattle from South Washington Street to Broad Street. The replacement of the seawall, built between 1916 and 1934, has become necessary because of significant deterioration that could result in severe failure from either wind-driven storm waves or an earthquake. The design of the replacement seawall involves a new earthquake-resistant system that will support the street and right-of-way; protect the shoreline and waterfront from coastal erosion; provide access to waterfront piers; allow public access to Elliott Bay; improve marine habitat; and support upland uses, public spaces, utilities, and buildings.

As part of the consultant team working with SDOT and USACE to replace the seawall, Floyd|Snider is providing consulting services regarding the management of contaminated sediment, soil, groundwater, and stormwater that will be encountered during construction of the new seawall structure.
