HAPPENING NOW
PROJECTS IN THIS AREA
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
Work on marine habitat at the intertidal area began in October 2018 with the arrival of a work barge and deployment of the containment boom.
Barge mounted cranes installed the foundation of the marine habitat with rocks.
A rock slinger was used to place various sizes of rocks.
A clamshell bucket was used to place different sizes of rocks.
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.
