A public comment period is open for the draft Supplemental Environmental Impact Statement (SEIS). Comments must be submitted by 5 p.m. on Feb. 20.  

The Duckabush draft supplemental environmental impact statement is available to download here. Comments can be submitted online here, or by visiting our WDFW SEPA page.

This Draft SEIS supplements the July 2016 Final Integrated Feasibility Report and Environmental Impact Statement. The Draft SEIS provides additional information and analysis of the impacts of the proposed Duckabush Estuary Restoration Project. A 30-day scoping comment period was held from June 27, 2019 through July 26, 2019.

The Washington Department of Fish and Wildlife (WDFW) selected four key elements of the environment for additional analysis in the Draft SEIS based on interest during the scoping process: Water; Plants & Animals; Transportation; and Noise.   

Public Hearing and Open House

A public hearing and open house with WDFW staff in attendance will be on Saturday Feb. 8 from 10 a.m. to 12 p.m at the Brinnon School (46 Schoolhouse Rd., Brinnon WA). Both oral testimony and written comments will be accepted.   

Project Background

WDFW, in partnership with the U.S. Army Corps of Engineers and the Hood Canal Salmon Enhancement Group (HCSEG), is proposing a restoration project on the Duckabush River estuary in Jefferson County. The project would occur primarily on public land at the Duckabush Wildlife Area Unit managed by WDFW.  

The project would reconnect the Duckabush River to neighboring floodplains and wetlands by modifying local roads and elevating Highway 101 onto a bridge spanning the area where freshwater from the Duckabush River meets saltwater of Hood Canal.  

The Duckabush River estuary is currently impacted by fill, dikes, and road infrastructure, which blocks water channels and limits critical habitat for fish and wildlife, including endangered salmon species.

This project would contribute to a Puget Sound-wide objective to restore river deltas and their wetlands. Over 50% of historical wetlands (57,823 acres) in Puget Sound’s 16 largest river deltas have been eliminated by development, which means there is significantly less natural habitat available for fish and wildlife to survive and thrive. 

Fortunately, the Duckabush estuary provides a valuable opportunity to restore important habitat that would provide long-lasting benefits to fish, wildlife, and people.  

Project-specific objectives

  • Reconnect and restore estuarine and freshwater tidal wetlands.
  • Re-establish channels to promote greater diversity of delta wetland habitats.
  • Restore mudflats and salt marsh.

Anticipated project benefits

  • Improved estuarine habitat for fish, birds, and wildlife, including endangered Hood Canal summer chum and chinook salmon, which is a main food source for endangered Southern Resident Killer Whales (Orcas).
  • Modernized highway design with updated safety features.
  • Improved opportunity for natural filtration of water flowing through the estuary.
  • Reduced seasonal flooding by eliminating existing water bottlenecks and allowing for natural tidal flows.

Community engagement

The Washington Department of Fish and Wildlife is committed to sharing timely project information with the local community, stakeholders, tribes and government agencies, as well as providing opportunities for comment during project planning.

Conceptual project design

A conceptual project design was developed as part of the Puget Sound Nearshore Ecosystem Restoration Project (PSNERP). The current design partnership with USACE, in conjunction with WSDOT and HCSEG, will incorporate site-specific data and public input to refine the conceptual design.

Project features include:

  • Relocate and elevate Highway 101 upstream to allow wetland habitat to be connected.
  • Remove existing Highway 101 fill, bridges and roadway to allow channels and wetlands to reconnect.
  • Remove levees/berms to allow channel migration.
  • Improve intersection of Highway 101 and Duckabush Road.
  • Modify Shorewood Road at Pierce Slough.
  • Excavate channels, increase habitat complexity, and plant native vegetation.
