This web page describes how WSDOT works with FHWA to evaluate potential highway impacts to public parks, recreation areas, wildlife or water fowl refuges, or historic sites. This process is required by Section 4(f) of the federal Department of Transportation Act (49 USC 303).
The information on this page is designed for a technical audience.
WSDOT's policy is to comply with FHWA's procedure for completing a Section 4(f) analysis. Chapter 457 of the Environmental Manual provides policy guidance.
