Fish Passage Program

Environmental stewardship is at the heart of a WSDOT program to correct fish barriers at hundreds of locations throughout the Pacific Northwest Region.

WSDOT’s $4B+ Fish Passage Program improves fish passage, reconnects streams and restores fish habitat to maintain a healthy waterway ecosystem. Driven by the agency’s environmental commitment and compliance with a 2013 U.S. Court injunction, WSDOT’s fish passage barrier corrections program has already completed more than 300 projects and restored an estimated 1,170 miles of habitat across the state.

To support all aspects of fish passage delivery in its Northwest Region, WSDOT awarded HNTB a General Engineering Contract in late 2019. In this role, HNTB serves as WSDOT’s owner representative for more than $2B in improvements in King, Snohomish, Skagit, and Whatcom counties.

Dozens of HNTB team members – geomorphologists, stream design and environmental engineers, project and procurement managers, roadway and structural engineers, utility engineers – rise each morning to meet the great challenge of this work, knowing they are making a difference.

HNTB is providing a wide range of planning, environmental, and engineering services from our Bellevue office. This work includes:

  • Developing and managing preliminary and final hydraulic designs (PHDs and FHDs) for stream restoration
  • Supporting environmental compliance and permitting for barrier replacement projects
  • Providing conceptual engineering and design-build procurement
  • Providing final engineering design for construction of upgrades to culverts and/or new bridges

The HNTB team also fills numerous critical staff augmentation positions for WSDOT’s Northwest Region. We work alongside our WSDOT colleagues on permitting strategies, environmental compliance, and coordination with Tribal partners. This work positions fish passage projects for advertisement and construction.
