AC was contracted by Parsons Brinkerhoff/WSP to provide the Bonneville Power Administration (BPA) with professional fisheries consulting services associated with this 98-mile transmission line rebuild project that extends from Eugene south to Coquille.
As part of NEPA planning and project permitting efforts, AC staff conducted initial fieldwork and prepared documentation for the Environmental Assessment for the project including fisheries technical reports. AC staff also conducted fisheries fieldwork for culvert and fish passage assessments, documenting site and channel conditions and making recommendations for bridge, culvert, and ford replacements associated with new road construction and existing road improvements. AC staff also prepared biological assessments for NMFS and USFWS to address potential impacts to ESA-listed fish species including UWR Chinook salmon, Oregon Coast Coho, and Oregon chub (subsequently de-listed).
As part of the project AC also provided design reviews for proposed culverts and bridges on fish streams to facilitate ODFW and NMFS Fish Passage Engineer approvals, prepared ODFW Fish Passage Plans for Stream-Road Crossings, conducted specifications reviews, and prepared planting plans and specifications for site restoration and revegetation.
