NCWRC staff have visited the site multiple times. 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 Rainbow Trout are found in the project vicinity, and in -stream work should be avoided between January 1 and April 15 to minimize impacts to trout reproduction. In addition, the Eastern Hellbender [Cryptobranchus alleganiensis, US Federal Species of Concern (FSC), NC Special Concern] is found in the Swannanoa River in the project footprint. Due to the sensitivity of these species to fine sediments, it is essential that excellent erosion and sediment control be maintained during the project. This site was the subject of a 2021 stream restoration project, but subsequent storms destabilized the site. The current project involves the stabilization of an eroding reach of river at four main work areas. Work will involve riffle adjustments (including adding riprap to existing riffles), log sills at existing log vanes, bank grading, toewood, and rock toe. The site would be planted in a native riparian buffer. It is extremely important to avoid existing hellbender habitat, as multiple hellbenders were captured on the site at the time of the last stream restoration project. Due to the potential for the project reach to support hellbenders, NCWRC biologists will survey for and relocate animals before the project begins.

In -stream work should be avoided between January 1 and April 15 to minimize impacts to trout reproduction. 2. The applicant should notify Lori Williams (lori.williams&ncwildlife.org) and Andrea Leslie (andrea.leslie(d),ncwildlife.org) at least 3 weeks before project construction is to begin so the affected reach can be surveyed for hellbenders and found animals relocated. 3. Be vigilant with sediment and erosion control during site staging, construction, and cleanup. Disturbed areas should be stabilized at the end of each day. 4. Work should be done at low flows. 5. Flows should be diverted away from work areas with coffer dams or other diversion devices. 6. 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. 7. Avoid disturbing large rocks as much as possible, as hellbenders can use them for shelters. Do not harvest in -stream boulders to create habitat structures, as these boulders may already provide hellbender habitat. 8. Avoid heavy equipment access in the channel as much as possible. This is especially important where larger rock is present that could harbor hellbenders. 9. If Eastern Hellbenders are disturbed during construction, they should be captured in a bucket and moved away from the area of disturbance. Contact Lori Williams (lori.williams(ancwildlife.org) if animals are seen. 10. Due to the possibility of hellbender impacts, we request a pre -construction meeting with the construction and design firms that involves the commenting agencies, including NCWRC. Thank you for the opportunity to review and comment on this project. Please contact me at (828) 400-4223 if you have any questions about these comments.
