Our comments on this application are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). Wild trout reproduction should not be impacted by the project, and a trout moratorium is not required for the project. The project involves the stabilization of an unstable reach of stream. A number of features would be installed to arrest headcuts and reduce erosive flows, including two rock ramps at active headcuts, one rock sill, four woody checks, and six permeable large woody debris structures. On 9/15/2021, NCWRC staff attended a site visit with the project design team at Givens Estate, where a similar strategy was used. For the current project, we strongly recommend using much less riprap and more wood in the structures. We offer the following recommendations to minimize impacts to fish and wildlife resources: 1. Be vigilant with sediment and erosion control during site staging, construction, and cleanup. Disturbed areas should be stabilized at the end of each day. 2. Work should be done at low flows. 3. Any erosion control matting used should be free of nylon or plastic mesh, as this type of mesh netting frequently entangles wildlife and is slow to degrade, resulting in a hazard that may last for years.
