Overview

The Corps of Engineers has partnered with the City of Seattle Department of Transportation (SDOT) to conduct a fesaibility study under the Corps' Coastal Storm Risk Management authority.  The feasibility study is $9.5 million cost-shared study to evaluate the feasibility of replacing the current aging seawall structure that provides coastal storm protection for downtown Seattle's central waterfront.  The new seawall will protect critical transportation and freight corridors, public and private utilties, emergency services, local commerce infrastructure, and residential properties.  The study area extends from South Washington Street to Broad Street at the north end. 

The Corps and SDOT are currently evaluating several plans to provide protection to the central downtown waterfront. Shoreline stabilization for the seawall appears to be the most effective solution in addressing public safety needs. In addition, the Corps will continue to evaluate a no-action alternative as a requirement under the National Environmental Policy Act (NEPA).
