Land uses surrounding the area are primarily agriculture (pasture) with some forested land to the northeast (Figure 3). It will occur around the intersection of Deer Park Road (Old Ferry Road) and Dairy Road. Both of the streams to be restored (Dairy Branch and Sheep Branch) parallel and are in close proximity to these road right-of-ways. Dairy Branch flows into Sheep Branch, which then flows approximately 0.2 miles south to the French Broad River. Stream banks along both streams are eroding and much of the riparian vegetation is inadequate with native trees and shrubs mostly absent and exotic and invasive plants abundant. Representative photographs are included in Attachment B. Section 13.3d Explain the purpose of the proposed project. The purpose of the proposed project is to use natural materials and methods to restore two stream sections severely impacted by bank erosion and poor riparian cover. Improvements include channel modifications, slope adjustments, removing exotic and invasive plants in the riparian buffer, and planting native trees and shrubs. Section 13.3e Project Description — Details The total limits of disturbance for this project will be 1.6 acres, which includes the areas for stream channel restoration, riparian buffer improvements, and construction access and staging. See Attachments B (Engineering Sheets) and C (Supplemental Information) for engineering details. The project will impact 875 linear feet (0.13 ac) of existing stream channel; 640 linear feet (0.103 acres) will occur on Sheep Branch and 235 linear feet (0.027 acres) on Dairy Branch. On Dairy Branch, stabilization measures will include approximately 60 linear feet of geolift, an approximately three foot wide bench, and bank adjustments to a 2:1 slope (see Sheet 3 in Attachment B). Three constructed riffles will also be installed to improve instream habitat, each will be approximately 30 linear feet. On Sheep Branch, the upstream 450 linear feet will be adjusted and relocated within the existing channel or adjacent to it to create a series of meanders to improve channel sinuosity (see Sheet 4 in Attachment B). The streambank slopes will range from 2:1 to 3:1 and an approximately 40 foot long constructed riffle will also be installed. The downstream 190 linear feet will remain in its existing channel but the streambanks will be modified to a 2:1 slope. Additional improvements throughout the project area will include invasive plant removal and planting native grasses, shrubs and trees (lives stakes) in the riparian buffer. The buffer width will be approximately 25 feet wide and existing mature trees will be protected, where possible. Typical construction and grading equipment (trackhoe, dozer, drum -roller, etc.) will be used and operated from high ground as much as possible, and also stay within the limits of disturbance. In - stream work will be required to install channel plugs and constructed riffles. Erosion and sediment control measures will include silt fencing along streambanks and stockpiles, and working in the dry where new channels will be created. Section F.Sd Endangered Species and Designated Critical Habitat — Sources Information about federally threatened and endangered species was gathered using the USFWS and NC Natural Heritage Program on-line tools (Appendix D). The USFWS IPaC "Official Species List" lists six species as potentially occurring within the project boundary: Common Name Scientific Name Status Appalachian elktoe Alasmidonta raveneliana Endangered Bog turtle Glyptemys muhlenbergii Threatened (Similarity of Appearance) Gray bat Myotis grisescens Endangered Mountain sweet pitcher -plant Sarracenia rubra ssp. jonesii Endangered Northern long-eared bat Myotis septentrionalis Endangered Rock gnome lichen Gymnoderma lineare Endangered Habitat within and adjacent to the project area consists of pasture and upland forest. No naturally occurring suitable habitat for the gray bat (caves), bog turtle (mountain bog), mountain sweet pitcher plant (mountain bog), Appalachian elktoe (cool, well -oxygenated, medium-sized streams with moderate to fast flowing water), and rock gnome lichen (humid environments with rock outcrops at high elevation or deep river gorges) were observed in the project area. Also, no trees are expected to be removed, which could be inhabited by the northern long-eared bat. Therefore, it is ClearWater's opinion that the project is not likely to adversely affect any protected species. The NC NHP database indicated element occurrences of the Appalachian elktoe and bog turtle within one -mile of the project area. Suitable habitat for the elktoe and bog turtle are not present within the project area, but the elktoe is found within the French Broad River, which is approximately 0.2 miles downstream of the project area. With adequate erosion and sediment control measures in place, no impacts to this species are expected. The NHP database also indicated the federally endangered bunched arrowhead (Sagittaria fasciculata) was found within one -mile, though the last sighting was in 1896 and suitable habitat of shaded wetlands are not present within the project area. Therefore, it is ClearWater's opinion that no impacts will occur to this species. Section F.7b. Historic or Prehistoric Cultural Resources — Sources Data were gathered from National Register of Historic Places records maintained by the NC State Historic Preservation Office (SHPO) and available on SHPO's HPOWEB GIS Service (accessed November 30, 2022). The project site is within the Biltmore Estate AD & Boundary Reduction historic property (status: NR, site ID BN1835). The Biltmore Estate (status: NR; site ID BN004) is also approximately one mile to the southeast. Because construction activities will be confined to the project area, it is ClearWater's opinion that project activities will not adversely affect these historic properties.

The enclosed species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). Please note that new species information can change your official species list. Under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. The Service recommends you visit the ECOS-IPaC website at regular intervals during project planning and implementation to ensure your species list is accurate or obtain an updated species list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. A biological assessment (BA) or biological evaluation (BE) should be completed for your project. A BA is required for major construction activities (or other undertakings having similar physical impacts) considered to be Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)) (NEPA). For projects other than major construction activities, the Service suggests that a BE be prepared to determine effects of the action and whether those effects may affect listed species and/or designated critical habitat. E?ects of the action are all consequences to listed species or critical habitat that are caused by the proposed action, including the consequences of other 11/30/2022 activities that are caused by the proposed action. A consequence is caused by the proposed action if it is reasonably certain to occur and would not occur "but for" the proposed action.. Recommended contents of a BA/BE are described at 50 CFR 402.12. More information and resources about project review and preparing a BA/BE can be found at the following web link: https://www.fws.gov/ ffice/asheville-ecological-services/asheville-field-office-online-review- process-overview. If a Federal agency determines listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. The Service is not required to concur with "no effect" determinations from Federal action agencies. If consultation is required, the Service recommends that candidate species, proposed species, proposed critical habitat, and at -risk species be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or licensed applicants, can be found in the "Endangered Species Consultation Handbook" at the following web link: https://www.fws.gov/media/endangered-species-consultation- handhnnk_ Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Act, there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project - related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). More information about MBTA and BGEPA can be found at the following web link: https://www.fws.gov/program/migratory-birds. We appreciate your consideration of Federally listed species. The Service encourages Federal agencies to include conservation of threatened and endangered species in their project planning to further the purposes of the Act. Please contact our staff at 828-258-3939, if you have any questions. In any future correspondence concerning this project, please reference the Consultation Code which can be found in the header of this letter. Attachment(s): ■ Official Species List ■ USFWS National Wildlife Refuges and Fish Hatcheries ■ Migratory Birds ■ Wetlands 11/30/2022 Official Species List This list is provided pursuant to Section 7 of the Endangered Species Act, and fulfills the requirement for Federal agencies to "request of the Secretary of the Interior information whether any species which is listed or proposed to be listed may be present in the area of a proposed action".

Species on this list should be considered in an effects analysis for your project and could include species that exist in another geographic area. For example, certain fish may appear on the species list because a project could affect downstream species. IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA Fisheriesi, as USFWS does not have the authority to speak on behalf of NOAA and the Department of Commerce. See the "Critical habitats" section below for those critical habitats that lie wholly or partially within your project area under this office's jurisdiction. Please contact the designated FWS office if you have questions. 1.

INC DEPARTMENT OF no on NATURAL AND CULTURAL RESOURCES ■ son November 29. 2022 Eric Romaniszyn ClearWater Environmental Consultants, Inc. 145 7th Avenue West Hendersonville, NC 28792 RE: Sleepy Hollow Stream Restoration Dear Eric Romaniszyn: D_ Reid Wilson, Secretary Misty Burhanan Deputy Director, Natural Heritage Program NCNHDE-20106 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence, the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: httr)s://www.fws.ciov/offices/Di rectory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund easement, or Federally - listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rod nev.butlerLncdcr.govov or 919-707-8603.
