OUR PROJECTS

The Impact Design and NW Fish Passage Team provided project management, civil engineering design, hydraulic analysis, and permitting support for the construction of six failing culverts for the Sudden Valley Community Association. Two of the culverts were held to Fish Passage Standards by the Washington State Department of Fish and Wildlife and required Army Corps of Engineers JARPA permit and Hydraulic Project Approval. Our team prepared and submitted all permits including local Land Disturbance Permitting with Whatcom County. The project was supported by The Nooksack Salmon Enhancement Association (Contact Darrell Grey). The two fish passage culverts were permitted as concrete box culverts and additional open channel habitat. Other culverts were replaced with HDPE piping.
