Endangered Species Act and Essential Fish Habitat

If a Washington State Department of Transportation (WSDOT) project has a federal nexus (the project receives federal funding, a federal permit, or occurs on federal land), work must comply with Section 7 of the Endangered Species Act (ESA) and the Magnuson-Stevens Fishery and Conservation Act (EFH). Use the webpages linked below to determine if your work has the potential to affect protected species and how to comply with the applicable laws.

If your project may affect a species or protected habitat, but does not have a federal nexus, contact the Fish & Wildlife Program Manager.

Find out how to comply with the ESA and EFH. Determine what documentation you will need for your project.

Find out if there are listed species and designated critical habitat in the project area. Find news about recent changes in ESA listings from U.S. Fish and Wildlife Service (USFWS) and NOAA Fisheries (NMFS).
