Stream restoration activities will also cause permanent impacts to 0.03 acre and temporary impacts to 0.26 acre of wetland. 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 should not be impacted by the project, and project activities do not need to be avoided during a trout moratorium. However, the site is just upstream of Caney Fork, which is part of the Tuckasegee River Aquatic Habitat a natural area recognized by the NC Natural Heritage Program and rated Exceptional due to the richness of rare species it supports. In the vicinity of the project, these rare species include the Eastern Hellbender [Cryptobranchus alleganiensis, NC Special Concern (SC)], French Broad River Crayfish (Cambarus reburrus, NC SC), Smoky Dace (Clinostomus sp., NC SC), and Wounded Darter (Etheostoma vulneratum, NC SC). We support this project, as is intended to reconnect the stream to its floodplain, improve wetland hydrology, and enhance riparian, wetland, and stream habitat. The application proposes to remove a perched culvert, establish a new channel for a large portion of the stream reach, stabilize stream banks and improve habitat and bedform diversity with a combination of bank sloping, in -stream structures, brush toes, soil lifts, and planting native woody and herbaceous vegetation. I spoke with Grant Ginn of Stantec, and he stated that instream work will be performed in the dry. It is particularly important to use extra care with erosion and sediment control on this project due to the rare species present in Caney Fork and the Tuckasegee River.

In -channel work should be accomplished as quickly as possible and vigilance used in sediment and erosion control during site preparation, construction, and clean up. Disturbed areas should be seeded, mulched and/or matted as soon as possible, preferably at the end of each work day. 2. 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. Thank you for the opportunity to review and comment on this project. Please contact me at (828) 803-6054 if you have any questions about these comments.
