I attended a design meeting on January 10, 2024. 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). There are Brook Trout and Brown Trout in the project vicinity, and in -stream activities should be avoided between October 15 and April 15 to minimize impacts to trout reproduction. The project site is part of the Bluff Mountain Natural Area, a NC Natural Heritage Program natural area rated as Exceptional due to the richness of rare species and its ecological significance. The Bog Turtle [Glyptemys muhlenbergii, US Threatened (T) due to Similarity of Appearance, NC T], Orange - barred Carpet Moth [Dysstroma hersilata, NC Significantly Rare (SR)], A Looper Moth (Polychrisia morigera, NC SR), and Roan Sedge (Carex roanensis, NC SR) are found in the ecologically important bog adjacent to the stream. In addition, Long-bracted Frog Orchid (Dactylorhiza viridis, NC Endangered) and Elliptic Shinleaf (Pyrola elliptica, NC T) are found near the project site. The application proposes to stabilize an unstable reach of stream that is threatening to encroach on the bog through installing j-hooks, boulder revetment, rootwads, and toewood, grading the banks, and excavating excess sediment deposition. A native riparian buffer will be planted, and a 50-ft conservation easement will be implemented. An additional 574 ft of channel where no in - stream work will be performed will be live -staked. Due to the size and geomorphology of the stream, in -stream work will be isolated either with a pump -around or with a temporary diversion structure. The work will be overseen by the project engineer. If flows are diverted from the Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 UT Three Top Creek Restoration Page 2 January 11, 2024 UT Three Top Creek, Ashe Co channel, construction staff should rescue any stranded Brook Trout from the affected reach. The bog will be completely avoided, with no equipment allowed within it. We appreciate the coordination with the project team. We offer the following recommendations to minimize impacts to the aquatic community: 1. 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. 3. In -stream activities should be done outside the October 15 to April 15 trout moratorium to minimize impacts to Brook Trout spawning. 4. When flows are diverted from the channel, construction staff should rescue any stranded Brook Trout from the affected reach. Thank you for the opportunity to review and comment on this project.
