Sharon Amity Road #411 Charlotte, North Carolina 28211 SUBJECT: Pre -Construction Notification Application for Reedy Fork Industrial at 5955 Summit Avenue in Browns Summit, Guilford County; USACE Action ID: SAW-2019-02059; DEQ Project No. 20210915v1. Dear Ms. Robertson, Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the subject document. Comments are provided in accordance with provisions of the Clean Water Act of 1977 (as amended) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667e), and North Carolina General Statutes (G.S. 113-131 et seq.). Atlas Environmental, on behalf of SL Reedy Fork LLC, has submitted Pre -Construction Notification (PCN) application and an Individual Water Quality Certification application for the proposed Reedy Fork Industrial project, an approximate 158.5-acre development located at 5955 Summit Avenue in Browns Summit, Guilford County, North Carolina. The proposed project would permanently impact a total of 0.193 acres of jurisdictional wetlands, 46 linear feet of intermittent streams, and 322 linear feet of perennial streams. Streams impacted by the project are unnamed tributaries of Reedy Creek in the Cape Fear River basin. Reedy Creek is classified as a Water Supply-V and Nutrient Sensitive Water by the NC Division of Water Resources. We have records for the state threatened triangle floater (Alasmidonta undulata), state special concern notched rainbow (Villosa. constricta), and state significantly rare eastern creekshell (V. delumbis) within Reedy Fork. Additionally, the state special concern Greensboro burrowing crayfish (Cambarus catagius) has been documented in Guilford County; however, the full extent of its distribution in this watershed is unknown due to lack of targeted surveys. The Greensboro burrowing crayfish has been found in all types of soils from sandy loams to hard clay and burrows are not usually directly associated with any drainage or stream flow (McGrath 1994). A portion of the site is designated as the Brown's Summit Forest/Hardy's Millpond Natural Heritage Natural Area (NHNA); natural areas are sites with special biodiversity significance. Overall, the lack of records from the site does not imply or confirm the absence of federal or state -listed species. An on -site survey for listed species is the only definitive means to determine if the proposed project would impact rare, threatened, or endangered species.

We offer the following recommendations minimize impacts to aquatic and terrestrial wildlife resources. 1. Further minimize impacts to streams and wetlands. 2. We request site inspections for the Greensboro burrowing crayfish. We have included an information sheet on preliminary site inspections for this species. Please notify Brena Jones, Central Aquatic Wildlife Diversity Coordinator (brena jones@ncwildlife.org, 919-707-0369), if any potential Greensboro burrowing crayfish or burrows are located. 3. Due to the presence of state -listed species and a NHNA, we strongly recommend a minimum 100-foot undisturbed buffer for perennial streams or the NHNA, whichever is greatest, and a 50- foot undisturbed buffer for intermittent streams and wetlands. 4. For any surface parking or roads, we recommend using bioretention cell in parking lot medians, for example, that can collect stormwater from the building and parking area. Additional information can be found at the NC State University's guide: http://www.onsiteconsortium.org/npsdeal/NC_LID_Guidebook.pdf. 5. The applicant should avoid the removal of large trees. Due to the decline in many tree -roosting bat populations, trees should not be removed during the maternity roosting season for bats (May 15 — August 15). 6. The directional bore stream crossing method should be used for utility crossings rather than open - cut stream crossing method to prevent the likelihood of future lateral movement of the stream, causing undercutting or erosion around the utility line. The open -cut stream crossing method should only be used when water level is low and stream flow is minimal. 7. All stormwater outlets should drain through a vegetated upland area prior to reaching any stream or wetland area. Sufficient retention designs should be implemented to allow for the slow discharge of storm water, attenuating the potential adverse effects of storm -water surges; thermal spikes; and sediment, nutrient, and chemical discharges. 8. Incorporate the following elements into erosion and sediment control plans: minimize clearing and grading, protect waterways, phase construction for larger construction sites (>25 acres), stabilize soils as rapidly as possible (<2 weeks), protect steep slopes, establish appropriate perimeter controls, employ advanced settling devices, implement a certified contractors program, and regularly inspect erosion control measures. Ensure all silt fencing is removed once vegetation has reestablished and soils have stabilized. 9. Disturbed areas should be reseeded with native seed mixtures that are beneficial to wildlife. The applicant should consider planting native, wildflower seed mixes and plants that will create pollinator habitat, which would also improve the aesthetics of the project and within rights -of - way. Bermudagrass, redtop, tall fescue, and lespedeza, which are invasive and/or non-native species, should not be used and these species provide little benefit to wildlife. In lieu of lawn or grassy areas, we recommend planting native pollinator species or other native vegetation. Avoid using invasive, non-native plants in seed mixtures or landscaping plants (http://www.ncwildflower.org/plant_galleries/invasivesiist). 10. Due to the presence of state -listed species downstream of the project and a NHNA, use strict sediment and erosion control measures, which should be installed prior to any land clearing or construction. The use of biodegradable and wildlife -friendly sediment and erosion control devices is strongly recommended. Silt fencing, fiber rolls and/or other products should have 20 September 2021 Reedy Fork Industrial USACE Action ID: SAW-2019-02059 Page 3 WRC Comments loose -weave netting that is made of natural fiber materials with movable joints between the vertical and horizontal twines. Silt fencing that has been reinforced with plastic or metal mesh should be avoided as it impedes the movement of terrestrial wildlife species. These measures should be routinely inspected and properly maintained. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. 11. We recommend using a bridge or using stream simulation design to install a bottomless culvert where footers are positioned outside the bankfull and storm surge. If a box culvert must be used, it must be designed to allow for aquatic life and fish passage. Generally, the culvert or pipe invert should be buried at least 1 foot below the natural streambed (measured from the natural thalweg depth). If multiple barrels are required, barrels other than the base flow barrel(s) should be placed on or near stream bankfull or floodplain bench elevation (similar to Lyonsfield design). These should be reconnected to floodplain benches as appropriate. This may be accomplished by utilizing sills on the upstream and downstream ends to restrict or divert flow to the base flow barrel(s). Silled barrels should be filled with sediment so as not to entrap wildlife or support mosquito breeding conditions. Sufficient water depth should be provided in the base flow barrel(s) during low flows to accommodate fish movement. If culverts are longer than 40-50 linear feet, alternating or notched baffles should be installed in a manner that mimics existing stream pattern. This should enhance aquatic life passage: 1) by depositing sediments in the barrel, 2) by maintaining channel depth and flow regimes, and 3) by providing resting places for fish and other aquatic organisms. In essence, base flow barrel(s) should provide a continuum of water depth and channel width without substantial modifications of velocity. If multiple pipes or cells are used, at least one pipe or box should be designed to remain dry during normal flows to allow for wildlife passage. Culverts or pipes should be situated along the existing channel alignment whenever possible to avoid channel realignment. Widening the stream channel must be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage. Riprap should not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage. Bioengineering boulders or structures should be professionally designed, sized, and installed. Thank you for the opportunity to comment on this permit application.
