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.

March 23rd, 2017 – Construction Update: 

After weeks of prep work, jet grout installation has begun north of Pine Street. This is exciting because it marks a major construction milestone on the last section of the seawall. The jet grout will form underground columns that protect the seawall against seismic activity and provide the foundation for the future waterfront.
