About the project

Working with community partner Alliance for Pioneer Square, we will design and construct improvements on portions of Main, Washington and King streets and Yesler Way between Alaskan Way and 2nd Avenue S, to prioritize pedestrians, improve sidewalks and increase greenery on these east-west streets.

The Washington Street Boat Landing and Beach will restore access to the waterfront for Pioneer Square and the South Downtown community. The landmark pergola structure has been a piece of Seattle's waterfront since the early 20th century, and with its recent restoration, it once again serves as a symbolic gateway to the city from the Puget Sound. The pergola has been fully restored, but it will remain closed to the public until the park promenade has been constructed. 

Between Colman Dock and Pier 48, a new habitat beach supports the waterfront ecosystem, including enhancing the salmon corridor by adding rocks and nearshore vegetation. These two together create an exciting destination and will help connect Pioneer Square and the South Downtown community back to the waterfront. Construction on the beach is complete, but to preserve the growing young vegetation, the beach is closed to the public and will be open once construction of the park promenade is complete.

Habitat Beach is a national winner of the American Public Works Association's 2020 Project of the Year Award!

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.
