PROJECTS IN THIS AREA

New Alaskan Way Construction

Waterfront Seattle will be building a new Alaskan Way in the footprint of the former viaduct. Starting as soon as the week of November 4, our initial work zones will span from S King to Marion streets. Activities include establishing work zones, mobilizing equipment, potholing work, breaking pavement and excavation for utility installation. Work is scheduled Monday through Friday, 7 AM to 5 PM with occasional overnight and weekend work. For more information, view the Alaskan Way Construction Flyer.

Habitat Beach

Improvements to the marine habitat south of Colman Dock began in October 2018 thanks to an agreement between Washington State Ferries and the City of Seattle to make these improvements on State-owned property. The plantings on the shoreline will restore the function of a natural shoreline and improve ecosystem productivity. We will need to patiently wait for a few years for the plants to grow and habitat to adapt to the natural environment before Habitat Beach is open to the public.

HOW WE’RE BUILDING IT

Over 45,000 tons of material including; sand, gravel, soil, sand, shells, and rocks of varying sizes make up the intertidal shoreline.

The completed area will be made up of a variety of materials to mimic the existing ecosystem of Elliott Bay.

These habitat marine enhancements will foster young growing nearshore vegetation, providing hiding places for fish and improving conditions for salmon, in order to preserve the waterfront ecosystem.
