The City of Seattle is rebuilding Seattle’s central waterfront. Now that the Alaskan Way Viaduct removal is complete, the City is constructing a park promenade along the water, building a new surface street along Alaskan Way, rebuilding Pier 58 and Pier 62, building an elevated connection from Pike Place Market to the waterfront, and improving east-west connections between downtown and Elliott Bay. This effort, called Waterfront Seattle, is a $806M, multi-year investment between now and 2025. It is led by the City of Seattle’s Office of the Waterfront and Civic Projects.


The Waterfront Seattle Program began as a community vision to remove the Alaskan Way Viaduct and reconnect the city to its waterfront. Since 2010, over 10,000 people have participated in visioning sessions, community meetings, walking tours and environmental reviews to shape the project we are now building.

Environmental process overview

In accordance with the Washington State Environmental Policy Act (SEPA), the City of Seattle has completed evaluation of the potential impacts to the natural and built environment that could result from the planned improvements to the waterfront.

As of 2019, the City of Seattle has released the Final Environmental Impact Statements (EIS) for Alaskan Way, the park promenade and bike path, the Overlook Walk and the Seawall. Other infrastructure improvement projects along the waterfront, such as the public piers, will undergo SEPA review in the future as design progresses. More information will be added to this page as environmental review for these projects begins.

To learn more about the environmental review process, read our Environmental Process 101 fact sheet.

Alaskan Way, Promenade + Overlook Walk

Environmental review of Alaskan Way, Promenade and Overlook Walk began with EIS scoping in 2013, continued with the release of the Draft EIS in 2015 and the Supplemental Draft EIS in 2016, and concluded in 2016 with the release of the Final EIS.


Environmental review of Seawall began with EIS scoping in 2010, continued with the release of the Draft EIS in 2012, the Final EIS in 2013, the Draft Supplemental EIS in 2013, and concluded in 2014 with the release of the Final Supplemental EIS.
