Stream restoration

Correcting high priority fish passage barriers and repetitive stream bank and shoreline erosion problems, also known as chronic environmental deficiency (CED) sites, reduces the state transportation system’s impact on fish and fish habitat. The Stream Restoration Program oversees and coordinates Washington State Department of Transportation (WSDOT) work to correct CED sites, and to deliver the multi-billion dollar fish passage barrier correction program.

Policies & procedures

Our policies and procedures describe the criteria for defining, nominating, and assessing a CED site, as well as the data driving the fish passage program and design guidelines to correct fish passage barriers.

Fish passage policies and procedures

The agency created the fish passage program in 1991 to inventory, prioritize, and correct fish passage barriers along Washington State Department of Transportation (WSDOT) highways. This program has dedicated funding to target correction of high priority fish passage barriers through stand-alone fish passage projects.

Chronic environmental deficiency (CED) policies & procedures

Chronic Environmental Deficiencies (CEDs) are locations along the state highway system where recent, frequent, and chronic maintenance repairs to the state transportation system are causing impacts to fish and fish habitat. In 2002, the Washington State Department of Transportation (WSDOT) established a partnership with the Washington Department of Fish and Wildlife (WDFW) to move away from the repetitive repair of WSDOT roads. CED site restoration concentrates on long-term solutions that will optimize improvements for fish and fish habitat, while also addressing transportation needs.
