Foundation of Seattle's waterfront
The Seawall Project is constructing a replacement seawall along Seattle's waterfront to protect critical infrastructure and utilities while enhancing the habitat through this area. The new seawall meets current seismic standards and will last more than 75 years, serving as the foundation for projects transforming Seattle's future waterfront.
Construction continues between Lenora and Union streets
Construction work between Lenora and Union streets is underway. The Seattle Aquarium and other waterfront businesses will remain open and access will be maintained at all times. Click here more information about what you can expect in the coming months.

June 22nd, 2017 – Construction Update
With Tuesday marking the summer solstice, we move into summertime as permeation grout work continues. Permeation grout reinforces the seawall’s structure and is one of the last steps in reinforcing the seawall. Aside from permeation grouting, remaining work includes removing jet grout equipment from the work zone, along with restoration of utilities and roadway.
While construction continues north of Pike Street, we’re taking time to look back at construction activities over the years.
