Salisbury St. Archdale Building -9th Floor Raleigh, North Carolina 27699-1617 2Q 1 51 327 Subject: Pre -Construction Notification Pursuant to Nationwide Permit No. and Water Quality Certification No. 3885 Western Stream Initiative — Barrier Stream Enhancement Project Avery County, North Carolina Dear Ms. Higgins: DEC 2 902015 The Barrier Stream Enhancement Project area is located in Avery County, North Carolina near the intersection of US Route 19 East and Old Hanging Rock Road (Figure 1). The Barrier Stream Enhancement Project is part of the Western Stream Initiative (WSI) program which is a partnership between Resource Institute (RI) and the Natural Resource Conservation Service (NRCS) in its second year of implementation. The program seeks to complete projects on agricultural lands that have been identified by NRCS staff in Western North Carolina. These projects are typically somewhat longer and more challenging, in one or more respects, than traditional NRCS-funded projects. NRCS federal grants fund WSI and similar bank stabilization projects as agricultural best management practices for the purpose of reducing erosion and sedimentation into streams, installing complementary practices such as fencing and watering, and in some cases for habitat enhancement. NRCS approved Technical Services Providers (TSPS) are selected by, and contract with, RI to provide design and engineering services for the WSI projects. The designs adhere to NRCS standard practices. Sites generally seek to achieve stable banks and/or channel stability through bank sloping, structure installation or other minimally invasive methods. All bank slope and structural improvements are accompanied by stream bank planting. Existing buffers and vegetation are typically maintained or enhanced. On some project sites, more substantial work is required to abandon up -valley meanders orto otherwise correct instability related to pattern where such work can be justified. Construction work is being conducted by pre -qualified stream restoration contractors, selected by RI. These contractors have substantial experience in stream restoration projects and work in partnership with TSPS and RI to complete high quality bank and channel stabilization efforts under this program. RI has an agreement (attached) with landowners that agrees that RI will be the applicant. An Agent Authorization Form is attached which provides verification that Aaron Earley, the TSP for Wildlands Engineering, is acting for RI. Project Overview The Barrier Stream Enhancement Project proposes a combination of bank grading and channel stabilization work to approximately 1,813 linear feet (LF) of the North Toe River. Proposed channel stabilization includes the construction of in -stream structures and slight adjustments to stream pattern and profile (Figures 2 & 3). The project reach is experiencing bank erosion, especially along outside meanders, as a result of tight channel pattern and minimal stream bank vegetation. In -stream structures including log vanes, boulder spurs, constructed riffles, and boulder/stone toes will help stabilize bed and banks and create conditions for natural recovery. Previous stream Wildlands Engineering, Inc. • phone 704-332-7754 • fax 704-332-3306 • 1430 S. Mint Street, # 104 • Charlotte, NC 28203 stabilization efforts including two rock vanes and one root wad were installed by others to address channel instability that occurred after large flooding events approximately ten years ago. One existing rock vane that is no longer functional will be removed and material reused fortoe protection. The project also proposes to lay back eroding banks to a stable bank angle that can be matted and re -vegetated for long-term stability. There are two unnamed tributaries (UTi & UT2) that enter the North Toe River within the project reach. Minor grading may be necessary along UT2 to tie the channel into the slightly adjusted pattern of the North Toe River. No other work is proposed to these tributaries. Jurisdictional Determination WSI project sites being permitted by Wildlands Engineering (Wildlands) were discussed with Tasha Alexander of the US Army Corps of Engineers (USACE) Asheville Field Office in June, 201-4. Sites are on large streams and the primary activities are occurring on the large streams. On some sites, small tributaries/ditches are affected. In all instances, it appeared likely that tributaries were intermittent or perennial. When affected, impacts were included in the total. Ms. Alexander indicated that USGS topographic mapping (provided) and photographs should be sufficient when affected tributaries are present, and in order to verify the jurisdiction on the main stream. Wildlands Engineering performed a field delineation for the Barrier Site on October 29, 201-5. In addition to the North Toe River, two unnamed tributaries (UTI. & UT2) and two wetlands (Wetland A & B) were identified. The two tributaries exhibited continuous bed and bank, baseflow, and supported a variety of aquatic life (including macroinverterbrates, amphibians, aquatic mollusks, and fish). The two tributaries were classified as perennial using North Carolina Division of Water Resources Stream Identification Form (Version 4.1-1-). Wetlands A and B exhibited surface water, water stained leaves, high water table, algal mats, and/or saturation within 12 inches of the ground surface. These areas have been historically manipulated by agricultural practices and lack canopy and understory vegetation. The herbaceous layer within Wetland A was primary switchgrass (Panicum virgatum) and common rush (luncus effusus). Wetland B is a concave depression devoid with indicators of hydrology and hydric soils. A USACE Approved Jurisdictional Determination Form, USACE Wetland Determination Forms (DP1-- DP4), and North Carolina Division of Water Resources Stream Identification Forms are included in the package. Soil mapping based on the U.S. Department of Agriculture (USDA) NRCS Soil Survey for Avery County indicates soils within the project area are mapped as Dellwood cobbly sandy loam (DeB), Rosman loam (RoA), and Rosman sandy loam (RsB) (See Figure 4). The Dellwood cobbly sandy loam is described as a moderately drained soil found on floodplains that are occasionally flooded. These units are described as moderately to well -drained soils found on floodplains that experience occasional to frequent flooding. Proposed Impacts The proposed stream enhancement work will temporarily impact 1-,81-3 linearfeet of the North Toe River. Stream enhancement would include minor pattern and profile adjustments and in -stream structure installation to stabilize the stream and banks. Stream work will be conducted with trackhoes and tracktrucks. Stream crossings and in - stream work will be minimized to the extent feasible however in -stream work will be necessary to construct structures. Due to the large stream size (74 square miles drainage area), continuous pump around is not an option and some of the work will be performed in the wet. Final plans will prescribe to use off-line construction or short- term pump arounds whenever feasible, to avoid working in the wet. In -stream sediments are primarily sand, gravel, and cobble and, as such, are not susceptible to generate excessive turbidity or downstream impacts. Bank grading will be done with caution to avoid spillback and transport of graded sediments into the river. Impacts to the unnamed tributaries in the project area will be avoided as much as possible. An existing ford crossing of UTI. may be utilized to access the project area from Old Hanging Road. A mud mat may be installed over the channel during construction to minimize impacts however temporary impacts of approximately 15 LF are being accounted for on UTI.. Temporary impacts of 16 LF to UT2 will be necessary for construction access. Mud mats will be used for the temporary UT2 crossing. The channels at the crossings will be restored to pre-existing conditions after construction. A larger cross-sectional area and thalweg alignment at Station 1-1-0+85 of the North Toe River is proposed to establish a larger, stable cross-section in a tight meander bend. This will require laying back the right bank and result in a 0 - reduction of 20 LF of UT2 at its confluence with the North Toe River. The reduction will be classified as a permanent impact but result in a functional improvement to the North Toe River.

Barrier Site Stream Enhancement Project Page 1 Site Photographs Barrier Site Stream Enhancement Project Page 2 Site Photographs Mutual Agreement for Stream Restoration Project Resource Institute (RI) is a non-profit organization that assists organizations and individuals in carrying out projects to protect natural and human resources while promoting economic development. RI can assist with projects in a variety of ways, including, but not limited to, fund-raising, administering project funds, and contracting for services needed to complete a project. RI has recently adopted a project referred to as the Western North Carolina Stream Initiative to help farmers and landowners address eroding stream banks that are negatively affecting them through loss of property, hazards for livestock, sediment transport into a stream and degraded aquatic habitat. The farmer/landowner has either initiated an application for assistance through USDA/NRCS's EQIP program or has already signed an agreement/contract for assistance with USDA/NRCS's EQIP program. RI's role is to help attain the funding, for the design, construction oversight and unmet construction needs of the work for sites with current EQIP program agreements/contracts through USDA/NRCS. RI will assist the farmer/landowner by helping to address issues related to managing and contracting for the required design, planning, permitting and construction work for stream enhancement practices on the site, as well as necessary structure work, and bank stabilization. RI's t objective is to help address current water quality degradation issues; however, work cannot be guaranteed for acts of nature related to flood events. RI is working with NRCS, Conservation Districts and the farmer/landowner to help reduce those impacts as much as possible. In providing services to the farmer/landowner on this tract of land for stream restoration/stabilization activities to be performed we thereby mutually agree to the following items: 1. The farmer/landowner will allow ingress and egress for all activities related to the stream restoration/stabilization such as: surveys, engineering; construction, monitoring, etc. for RI and its agents. 2. Farmer/landowner will follow the contractual guidance in the EQIP program with USDA, NRCS. 3. Farmer/landowner will allow NRCS to provide RI with a copy of the associated NRCS EQIP, application, contract and/or contract modifications, and appendix for the purpose of allowing RI to sh e . 's other funders in an effort to help obtain matching dollars. (Initial/date) 4. RI will serve as the financial manager for all funds related to the stream restoration/stabilization activities received for the project. 5. RI will provide project management services such as, obtaining the technical resources, bidding and contracting of project elements, and project construction oversight. 6. RI will work with farmers/landowners to resolve differences between construction costs and payment schedule rates.

Non-regulated waters/wetlands (check if applicable):' Q Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Boxes checked below shall be supported by completing the appropriate sections in Section III below. '- For purposes of this form, an RP W is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 7 Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section HI.A.1 and Section III.D.I. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section HI.D.1.; otherwise, see Section HI.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non -navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section HI.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody4 is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: square miles Drainage area: 74 square miles Average annual rainfall: 49.62 inches Average annual snowfall: 42.8 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through l tributaries before entering TNW.

Explain: Project reach is located in a rural watershed where primarily land uses are forest and agriculture. Project reach was clear during site visit. Identify specific pollutants, if known: 6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 7Ibid.

Wetland A also captures some of the pasture runoff before it enters the North Toe River. C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1.
