DUCKABUSH ECOSYSTEM RESTORATION

4CUI

PROJECT PURPOSE AND NEED

Puget Sound Nearshore Ecosystem Restoration study authorized in 2016 for implementation

To restore the natural function of the Duckabush Estuary so that it can create and maintain estuarine habitat in a self-sustaining manner.

This is to be accomplished by removing or modifying existing features so that natural habitat forming processes can be restored.

This project will reconnect the Duckabush River with adjacent floodplains and wetlands by removing existing roadway fill.

5CUI

Improved tidal wetland habitat for fish and wildlife, including Hood Canal summer chum and Chinook salmon, a main food source for endangered Southern Resident Killer Whales.

Reduced backwater flooding.

Improved water quality resulting from increased wetland area for natural water filtration and new road run-off treatment areas.

Modernized road and utility infrastructure resulting in improved resiliency to climate change and natural disasters.

Creation of approximately 1,300 jobs throughout construction of the project.

Increased habitat connectivity and reduced wildlife-vehicle collisions by creating a wildlife corridor under U.S. Highway 101.
