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 needed. Cane Creek supports the Creeper mussel [Strophitus undulatus, NC Threatened (T)], Blotched Chub (Erimystax insignis, NC T), and Ohio Lamprey (Icthyomyzon bdellium, NC Special Concern). Excellent erosion and sediment control are needed to minimize impacts to these sensitive species. The project involves the establishment of a large residential development in the 100-year floodplain. The NCWRC does not support commercial or residential development within the 100-year floodplain. The filling of floodplains increases the potential for flooding and degrades in -stream habitats for fish and other aquatic organisms. Two reinforced concrete pipe (RCP) culverts are proposed along with riprap within the channel beds upstream and downstream of these pipes. Four wetland areas would be filled.

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. 2. Any erosion control matting used should be free of plastic or nylon 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. The application proposes using RCP culverts. We recommend against using smooth -walled RCP or high density polyethylene (HDPE) material, as these smooth materials are less likely to hold stream substrate and provide for movement of aquatic organisms like fish and salamanders. 4. Limit impervious surface to less than 10% or use stormwater control measures to mimic the hydrograph consistent with an impervious coverage of less than 10%. 5. Use non-invasive native species and Low Impact Development (LID) technology in landscaping. Using native species instead of ornamentals should reduce the need for water, fertilizers and pesticides. Using LID technology in landscaping will not only help maintain the predevelopment hydrologic regime, but also enhance the aesthetic and habitat value of the site. 6. Protect and plant native riparian buffers on the site and set aside non -developed areas as green space. Maintain open space areas with native vegetation.
