Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The properties are located approximately 3 miles southwast of the town of Zionville, NC in westerm Watauga County. The properties are located along Old US Highway 421. Dominant landuses in the general vicinity of the Subject Property include residential (suburban) and agricultural (crop/pasture). The sub -watershed draining to the project site includes farms and residential developments. The project site occurs approximately 4.5 miles upstream of Cove Creek's confluence with the Watauga River. The proposed Cove Creek Restoration Project Site is located along the riparian corridor of Cove Creek (river left & right), which traverses mulitple properties from north to south (approx). The Subject Properties contain houses and crop land. Streambanks at the project site are highly eroded and vertical in areas. Streambank vegetation is generally grassy with medium trees and some herbs.The topography at the site is gently sloping in the project area with elevations ranging from —2,775 - 2,785 ft. above mean sea level, becoming steeper to the east away from the project site exending up to 3,075 ft. above mean sea level. 3b. List the total estimated acreage of all existing wetlands on the property: 0 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: --2,313 In ft of Cove Creek on Subject Properties 3d. Explain the purpose of the proposed project: The goal of this project is to enhance and restore 2,313 In ft of Cove Creek. Streambank sloping and benching will occur throughout the reach to restore floodplain connectivity and decrease erosive incisement of the channel. Riffle -pool sequencing, natural channel structures, and a forested riparian buffer will also be restored along the reach. 3e. Describe the overall project in detail, including the type of equipment to be used: The restoration work proposed at the site will implement Natural channel design measures including streambank sloping and creation of a stable bankfull bench, j -hook, cross vane, wing deflectors, root wad structures, and riparian corridor planting. Streambank sloping/benching, construction of j -hook structure and wing deflectors, and reforestation of the buffer will occur along river left of all properties along the creek, and along river right in the uppermost extent of the project on the Winebarger property. Streambank sloping/benching will occur on the majority of river left areas on all properties. Equipment likely to be used for this proposed construction include track -hoes, skidsteers, and dump trucks for hauling equipment, building materials, and fill material.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The proposed work and associated impacts are intended to restore instream structure and floodplain connectivity at Cove Creek along the stream reach while minimizing impacts to aquatic resources. Design measures which minimize impacts include j -hook, toe wood, wind deflectors, and cross -vane structures intended to enhance stream diversity and decrease site sedimentation. Streambanks will then be planted with appropriate native species (see re-veg detail). Disturbed buffer areas will be immediately seeded upon completion (temporary - annual ryegrass), matted (coconut coir matting), and stabilized at the close of each construction day. Following construction, the banks of the restored channel will be seeded with a native floodplain mix (permanent seed). Live stakes and matting staples will be used to secure the coconut matting in these high - stress areas. Riparian buffer will be planted with a variety of native 1 -gallon trees following construction. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. All heavy equipment will be kept out of the stream channel during project construction except where absolutely necessary to install in -stream structures. Any entering of the channel or immediate riparian area will be done with new equipment, no hydraulic leaks tolerated. Disturbance of channel bottom, banks and equipment access areas shall be held to the minimum necessary to allow for bank stablization sufficient to restore the hydraulic capacity of the stream channel. 2.

Office of Archives and History Deputy Secretary Kevin Cherry There are four previously recorded archaeological sites at or in close proximity to the project area. The National Register eligibility of these sites has not been evaluated. The project area has never been systematically surveyed to determine the location or significance of archaeological resources. Based on the topographic and hydrological situation and the density of archaeological sites in Cove Creek valley, there is a high probability for the presence of prehistoric or historic archaeological sites. We recommend that a comprehensive survey be conducted by an experienced archaeologist to identify and evaluate the significance of archaeological remains that may be damaged or destroyed by the proposed project. The archaeological survey need only be conducted in those portions of the project area where ground disturbance is proposed. Potential effects on unknown resources must be assessed prior to the initiation of construction activities. Two copies of the resulting archaeological survey report, as well as two copies of the appropriate site forms, should be forwarded to us for review and comment as soon as they are available and well in advance of any construction activities. A list of archaeological consultants who have conducted or expressed an interest in contract work in North Carolina is available at www.archaeology.ncdcr.gov/ncarch/resource/consultants.htm. The archaeologists listed, or any other experienced archaeologist, may be contacted to conduct the recommended survey. Prior to initiation of fieldwork the archaeologist should consult with Western Office staff archaeologist, Linda Hall, at 828/296-7230 or linda.hallAncdcr�. We have determined that the project as proposed will not have an effect on any historic structures.

Thank you for your cooperation and consideration. If you have questions concerning the above comment, contact Renee Gledhill -Earley, environmental review coordinator, at 919-807-6579 or environmental.reviewAncdcr.gov.

Bartos United States Department of the Interior FISH AND WILDLIFE SERVICE Asheville Field Office 160 Zillicoa Street Asheville, North Carolina 28801 February 2, 2017 Emily Morris Brushy Fork Environmental Consulting, Inc. 5902 Highway 421 South Mountain City, Tennessee 37683 Dear Ms. Morris: Subject: Cove Creek Stream Restoration Project; Watauga County, North Carolina Log No. 4-2-17-176 The U.S. Fish and Wildlife Service (Service) has reviewed the information provided in your correspondence dated January 4, 2016 wherein you request our technical assistance regarding potential occurrences of federally protected species in the proposed project vicinity. The Service submits the following comments in accordance with the provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e); the National Environmental Policy Act (42 U.S.C. §4321 et seq.); and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). Project Description According to the information provided, you are seeking a NWT 27 for proposed impacts to 2,313 linear feet of Cove Creek near West Jefferson, North Carolina. The proposed project would incorporate natural stream channel design methodologies and instream structures including j - hooks, root wads, and riparian planting. Federally Listed Endangered and Threatened Species According to Service records, suitable summer roosting habitat may be present on site for the federally threatened northern long-eared bat. However, the final 4(d) rule (effective as of February 16, 2016), exempts incidental take of northern long-eared bat associated with activities that occur greater than 0.25 miles from a known hibernation site, and greater than 150 feet from a known, occupied maternity roost during the pup season (June 1 — July 31). Based on the information provided, the project (which may require tree clearing) would occur at a location where any incidental take that may result from associated activities is exempt under the 4(d) rule. The Service has record of no other federally protected species in the project area. Please be aware that in accordance with the Act, it is the responsibility of the appropriate federal agency or its designated representative to review its activities or programs and to identify any such activities or programs that may affect endangered or threatened species or their habitats. If it is determined that the proposed activity may adversely affect any species federally listed as endangered or threatened, formal consultation with this office must be initiated. We offer the following recommendations in the interest of protecting fish, wildlife, and other natural resources. Stream Channel and Bank Reconstruction/Restoration Activities A natural, stable stream system is one that is able to transport a wide range of flows and associated bed load (sediment) while maintaining channel features and neither degrading (accelerating the erosion of banks and scour of the channel bed) nor aggrading (accelerating the deposition of sediment within the channel). The majority of property damage associated with flood events in areas that contain, or are adjacent to, streams often can be tied to human -caused alterations within the stream corridor, such as the removal of streambank vegetation, channelization, and/or dredging of the stream and the placement of fill within floodplains. To avoid future damage and associated costs, it is critical that proposals to repair storm -damaged property within stream corridors emphasize the restoration of natural, stable stream conditions. Accordingly, we recommend the following: 1. Where possible, work in or adjacent to stream waters should be conducted in a dry work area by implementing stream diversions, barriers, and/or pump -around systems. 2. Reconstruction work should be staged such that disturbed areas would be stabilized with seeding, mulch, and/or biodegradable (coir) erosion -control matting prior to the end of each workday. No erosion -control matting or blankets should contain synthetic (netting) materials. Matting should be secured in place with staples; stakes; or, wherever possible, live stakes of native trees. If rain is expected prior to temporary seed establishment, additional measures should be implemented to protect water quality along slopes and overburden stockpiles (for example, stockpiles may be covered with plastic or other geotextile material). 3. We recommend planting deep -rooting woody vegetation along riparian areas where any channel work is accomplished. Tree and shrub plantings should be spaced at intervals no greater than 10 feet along stream banks. Vegetated riparian zone widths should be as wide as practical but should extend at least 30 feet from the stream channel. Invasive Exotic Species Without active management, including the revegetation of disturbed areas with native species, project corridors may become corridors for the movement of invasive exotic plant species. Exotic species are a major contributor to species depletion and extinction, second only to habitat loss. Exotics are a factor contributing to the endangered or threatened status of more than 40 percent of the animals and plants on the Federal List of Endangered and Threatened Wildlife and Plants.' It is estimated that at least 4,000 exotic plant species and 2,300 exotic animal species are now established in the United States, costing more than $130 billion a year to 1D.S. Wilcove, D. Rothstein, J. Dubow, A. Phillips, and E. Losos. 1998. Quantifying threats to imperiled species in the United States. Bioscience 48:607-615. control.' Additionally, the U.S. Government has many programs and laws in place to combat invasive species (see www.invasivespecies.gov). Specifically, Section 2(a)(3) of Executive Order 13112 - Invasive Species (February 3, 1999) directs federal agencies to "not authorize, fund, or carry out actions that it believes are likely to cause or promote the introduction or spread of invasive species in the United States or elsewhere." Despite their short-term erosion -control benefits, many exotic species used in soil stabilization seed mixes are persistent once they are established, thereby preventing the reestablishment of native vegetation. Many of these exotic plants' are also aggressive invaders of nearby natural areas, where they are capable of displacing already -established native species. Therefore, we strongly recommend that only species native to the natural communities within the project area be used in association with all aspects of this project. The Service supports the restoration objectives of this project. Please contact Mr. Byron Hamstead of our staff at 828/258-3939, Ext. 225, if you have any questions.

IkEISOUIRICE I `: STTT_Lrt'}N RC S : INSPECTION AND MAINTENANCE: This consists primarily of two components, stream stabilization structures (J -Hooks, Cross vanes, etc.) and planting of the stream banks and riparian areas. In the event that the stream structures shift, wash away, settle, or otherwise physically cannot function as designed, contact the area NRCS Agent. If the new plantings experience a mort ality rate of greater than 25%, the dead/dying plants will need to be replaced.
