As a member of a design team, Fain Environmental is performing geomorphic assessments for four culverts, three in the Southwest Region and one in the Olympic Region. We are preparing the Watershed and Site Assessment of the Preliminary Hydraulic Design Reports. We are working closely with the design team to ensure fish passage is achieved. Fain Environmental is providing information on grain size, determining the representative reference reach, and calculating the vertical and horizontal channel profile.
