The attached plan includes several important modifications from the Prospectus to incorporate suggestions from the IRT site visit in October 2017. In total the Draft Mitigation Plan presents 3,418 warm stream credits (versus 3,529 in the Prospectus). These modifications are based on an IRT site visit with Kim Browning, Mac Haupt, Andrea Leslie, and Olivia Munzer on October 16, 2017, a JD site visit with William Elliott, subsequent regulatory guidance, and changes from design inputs. The alterations are detailed below: • All stream origins in the project have been verified by the USACE and accurately mapped. • Reach FF4 has been broken into an Enhancement I section, and a Restoration section based on existing conditions and design. • Per IRT feedback Reach FF1-C is Enhancement II at a 3:1 ratio, which includes cattle exclusion, buffer planting, and leaving the stone wall in place. Coordination with SHPO has occurred and allows this approach. • Reach FF1-D has been designed for the valley and powerline constraints. • Per IRT feedback Reach FF5 is Enhancement III at a 7.5:1 ratio, except at the tie-in with Reach FF1-D (restoration). • Reaches FF3-A and FF3-B have been combined into Reach FF3-A with a treatment of Enhancement III at 7.5:1. • Reach FF2 is preservation at a 10:1 ratio and the upstream portion of the stream will fence out cattle up to the crossing adjacent to the property boundary. • Reach FF1-A is Enhancement II at 2.5:1; however, there will be some areas of bank stabilization done. • The easement boundary has been altered slightly based on conversations with the Landowner and restoration reach alignment. • The non-standard buffer width guidance was utilized for the Site. We look forward to discussing this project with you in more detail as your review progresses.

" EXECUTIVE SUMMARY The Green Mesa Mitigation Site ("the Project") is located in Yadkin County, approximately two miles south of Boonville, NC. Water quality stressors currently affecting the Project include livestock production, agricultural production, and lack of riparian buffer. The Project presents 9,335 linear feet (LF) of stream restoration, enhancement, and preservation, generating 3,418 Warm Stream Mitigation Units (SMU) along five unnamed tributaries. The Project is located in the Yadkin River Basin within Cataloging Unit 03040101, Hydrologic 12 - digit USGS HUC 03040101130010, and NCDWR sub -basin 03-07-02. This HUC ultimately drains into Deep Creek, which has a State classification as Class C waters (NCDWQ 2011). Consisting of agricultural fields, livestock pastures and wooded areas, the Project's total easement area is approximately 33.46 acres within the overall drainage area of 1,011 acres. Grazing livestock have historically had access to all stream reaches within the Project. The lack of riparian buffer vegetation, deep-rooted vegetation, and unstable channel characteristics have contributed to the degradation of stream banks throughout the Project area. Goals for the Project include an increase to hydrologic function and restoration to ecological function within the existing stream and riparian corridor and protect these features in perpetuity. These will be accomplished by returning the existing streams into stable conditions by constructing an E/C type stream with appropriate dimensions and pattern, reconnecting the channel to the floodplain, and backfilling the abandoned channel. In -stream structures will be utilized for vertical stability and to improve habitat. Buffer improvements will filter runoff from agricultural fields, thereby reducing nutrient and sediment loads to the channel. Livestock exclusion fence will be installed along the easement boundary. The widening and restoration of the riparian areas will also provide wildlife corridors throughout the Project area. Benefits to be accrued from these activities include improved water quality, and terrestrial and aquatic habitat. The stream design approach for the Project is to combine the analog method of natural channel design with analytical methods to evaluate stream flows and hydraulic performance of the channel and floodplain. The analog method involves the use of a reference reach, or "template" stream, adjacent to, nearby, or previously in the same location as the design reach. The template parameters of the analog reach are replicated to create the features of the design reach. The analog approach is useful when watershed and boundary conditions are similar between the design and analog reaches (Skidmore et al., 2001). Hydraulic geometry is developed using analytical methods to identify the design discharge. After completion of all construction and planting activities, the Project will be monitored on a regular basis throughout the seven-year post -construction monitoring period, or until performance standards are met. Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to Unique Places to Save (UP2S). This party shall serve as conservation easement holder and long-term steward for the property and will conduct periodic inspection of the site to ensure that restrictions required in the conservation easement are upheld. Endowment funds required to uphold easement and deed restrictions will be finalized prior to site transfer to the responsible party.

The Project lies within the Yadkin River Basin, North Carolina Department of Water Resources (NCDWR) sub -basin 03-07-02 and United States Geological Survey (USGS) 14 -digit hydrologic unit code (HUC) 03040101130010 (Figure 1). The Project is being designed to help meet compensatory mitigation requirements for stream impacts in the HUC 03040101. The Project proposes to restore 1,891 linear feet (LF), enhance 6,842 LF, preserve 602 LF of existing stream, and provide water quality benefit for 1,011 acres of drainage area. The Project is in the Northern Inner Piedmont Level IV ecoregion. The Project consists of a single landowner on six parcels. It is comprised of five unnamed tributaries totaling 9,315 existing linear feet, which eventually drain into the Yadkin River. The stream mitigation components are summarized in Table 1 and Figure 10. The Project is accessible from Baptist Church Road. Coordinates for the Project are as follows: 36.213246, -80.718195. 1.2 Project Outcomes The streams proposed for restoration have been significantly impacted by livestock production, agricultural practices, and a lack of riparian buffer. Proposed improvements to the Project will help meet the river basin needs expressed in the 2009 Upper Yadkin Pee -Dee River Basin Restoration Priorities (RBRP) as well as ecological improvements to riparian corridor within the easement. Through stream restoration, enhancement, and preservation, the Project presents 9,335 LF of proposed stream, generating 3,418 Warm Stream Mitigation Units (SMUT) (Table 1). This mitigation plan is consistent with the October 20, 2017 IRT site visit (Appendix H). Table 1.

The Project resides in the North Deep Creek HUC (03040101130010), which ultimately drains to the South Deep Creek Targeted Local Watershed (TLW 03040101130020). The Yadkin River headwaters exhibit both the need for wetland, steam, and riparian buffer restoration; more specifically the goals in the 2009 RBRP for the watershed include: 1. Restoration of water quality and aquatic habitat in impaired stream segments; 2. Protection of high -resource value waters, including HQ W, OR W, and WSW designated waters and those containing large numbers of rare and endangered species (Natural Heritage Element Occurrences); 3. Continuation of existing watershed restoration and protection initiatives and projects, including efforts funded by Clean Water Management Trust Fund (CWMTF), DWQ's 319 Program, NC EEP, Ag Cost Share Program (A CSP) and Community Conservation Assistance Program (CCAP); 4. Collaborative efforts with local resource agencies, land trusts and willing landowners to implement new stream, riparian buffer and wetland restoration, enhancement and preservation projects within TLWs; S. Improved management ofstormwater runoff (including the implementation of stormwater BMP projects), especially in urban and suburban areas contributing to downstream degradation of stream habitat and impairment of water quality; and 6. Implementation of agricultural BMPs in order to limit inputs of sediment, nutrients, and fecal coliform to streams from active farming operations. 2.1 Site Selection The Project was identified as a stream and buffer restoration opportunity to improve water quality, habitat, and hydrology within the Yadkin River Basin within the 2009 Upper Yadkin Pee -Dee RBRP. The site lends itself to accomplish multiple RBRP goals along Project reaches due to an absence of riparian buffers, livestock access to the stream, and the historic land use, which has led to channelization. Many of the Project design goals and objectives will address major watershed stressors identified in the 2009 RBRP. Project -specific goals and objectives will be addressed further in Section 5. A project watershed map with the Project's drainage areas is shown on Figure 2 and watershed planning priority boundaries are shown on Figure 1. The Project will address two of the six goals outlined in the 2009 Upper Yadkin Pee -Dee RBRP. Establishing riparian buffers, instream structures, and increasing bedform diversity will help address RBRP Goal 1, but achievement will not be quantified. The Project will include the use of agricultural BMPs to limit inputs of sediment, nutrients, and fecal coliform to streams from active farming operations (RBRP Goal 6). The land required for the construction, management, and stewardship of this Project includes six parcels in Yadkin County with the following ownership in Table 2 & Figure 3. Once finalized, a copy of the Green Mesa Mitigation Plan 2 August 2018 land protection instrument will be included in Appendix C. The Wilmington District Conservation Easement model template will be utilized to draft the site protection instrument. Table 2.

The total drainage area for the Project is 1,011 acres (1.58 mi'). Primary land use within the rural watershed consists of approximately 28 percent forest and 62 percent agricultural land. Impervious area covers less than two percent of the total watershed (Table 3 & Figure 4). Within the agricultural land use, pastureland accounts for approximately two percent of the area and cropland comprises 55 percent of the area. Historic and current land -use within the immediate Project area have had direct livestock access to the streams. These activities have negatively impacted both water quality and streambank stability along the Project streams. The resulting observed stressors include excess nutrient input, streambank erosion, sedimentation, livestock access to streams, channel modification, and the loss of riparian buffers. Table 3. Project Watershed Summary Information Level IV Ecoregion 45e — Northern Inner Piedmont River Basin Yadkin USGS Hydrologic Unit 8 -digit 03040101 USGS Hydrologic Unit 14 -digit 03040101130010 DWR Sub -basin 03-07-02 Project Drainage Area (acres) 1,011 Percent Impervious Area <2% Surface Water Classification The project drains into Deep Creek, which has been classified as Class C Waters (NCDWQ 2011). Class C waters are protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. Secondary recreation includes wading, boating, and other uses involving human body contact with water where such activities take place in an infrequent, unorganized, or incidental manner (NCDWQ 2011). 3.2 Landscape Characteristics The Project is located in the Northern Inner Piedmont Level IV ecoregion, which is characterized by rolling to hilly higher elevations than the Southern Outer Piedmont, more rugged topography, and more monadnocks or mountain outliers than other areas of the Piedmont. It has colder temperatures, more snowfall, and a shorter growing season than in Southern Inner, Southern Outer, Northern Outer, and Carolina Slate Belt Piedmont regions. It has mostly mesic soils rather than the thermic soils that cover other regions of the Carolina Piedmont. The region contains more Virginia pine and less shortleaf pine than Southern Outer Piedmont and Carolina Slate Belt, more chestnut oak, and many mountain disjunct plant species. Streams tend to have higher gradients than in the Outer Piedmont regions and contain many mountain -type macroinvertebrate species. Existing Vegetation Vegetation around the unbuffered reaches of the Project are primarily composed of herbaceous vegetation and some scattered trees. In general, these riparian zones are disturbed due to regular land management activities. On June 21, 2018 three 100m2 plots were surveyed along the floodplain of the Green Mesa Mitigation Plan 4 August 2018 Project to categorize the existing vegetation communities. Forested riparian areas along the majority of the Project have been intermittently livestock -grazed and lack a well-developed understory and shrub strata, while short reaches of enhancement and preservation represent more natural community assemblages. For this reason, representative plots were surveyed along reaches FF1-C, FF1-D, and FF2 (Appendix B). Within each vegetation plot, all trees >5 inches (12.7cm) diameter at breast height (DBH) were identified, measured, and used to calculate both basal area and stems per acre. Trees >54 inches (137cm) in height were used to quantify tree species diversity. Canopy species data was calculated to quantify the existing natural community (Schafale, 2012) (Table 4). Shrub species and herbaceous species were also identified, and the percent cover was estimated. Table 4. Green Mesa Vegetation Plot Summary Plot Basal Area (m2/ha) Avg.

Sub - canopy species included green briar (Smilax rotundifolia), service berry (Amelanchier arborea), poison ivy (Toxicodendron radicans), lowbush blueberry (vaccinium angustifolium), and sawtooth blackberry (Rubus argutus). Native herbaceous species in the enhancement and preservation reaches included Christmas fern (Polystichum acrostichoides), Virginia creeper (Parthenocissus quinquefolia), little heartleaf (Hexastylis minor), wild yam (Dioscorea villosa), American hog peanut (Amphicarpaea bracteate), common blue violet (Viola sororia), sessileleaf bellwort (Uvularia sessilifolia), yellow star grass (Hypoxis hirsute), white lettuce (Prenanthes alba), New York fern (Thelypteris noveboracensis), devil's grandmother (Elephantopus tomentosus), strawberry bush (Euonymus americanus), spear leaved violet (Viola hastata), frostweed (Verbesina virginica), long leaved bluet (Houstonia longifolia), Cinquefoil (Potentilla sp), ebony spleenwort (Asplenium platyneuron), white snake root (ageratina altissima), jewelweed (Impatiens capensis), smartweed (Polygonum sp.), tearthumb (Polygonum arifolium), golden rod (Solidago sp.), hairy agrimony (Agrimonia gryposepala), dogfennel (Eupatorium capillifolium), annual ragweed (Ambrosia artemisifolia), horse nettle (Solanum carolinense), sweetscented joe pye weed (Eutrochium purpureum), and common boneset (Eupatorium perfoliatum). Native grasses, sedges, and rushes present on preservation and enhancement reaches included deer -tongue (Dichanthelium clandestinum), globe flatsedge (Cyperus echinatus), and common sedge (Carex sp.). Invasive species were also found within the vegetation survey plots, and in the vicinity of the site: tree of heaven (Ailanthus altissima), Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiflora), and Japanese honeysuckle (Lonicera japonica). Non-native species included red clover (Trifolium pratense), white clover (Trifolium repens), Japanese stiltgrass (Microstegium vimineum), annual meadow grass (Poa annua), tall fescue (Festuca arundinacea), red fescue (Festuca rubra), bush clover (Lespedeza sp.), ox -eye daisy (Leucanthemum vulgare), pigweed (Amaranthus albus), and common stork's -bill (Erodium cicutarium). Green Mesa Mitigation Plan 5 August 2018 Existing Wetlands A survey of existing wetlands was performed on November 8, 2017. Wetland boundaries were delineated using current methodology outlined in the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987). Soils were characterized and classified using the Field Indicators of Hydric Soils in the United States, Version 7.0 (USDA-NRCS 2010). Within the boundaries of the proposed Project, two jurisdictional wetlands are present near Reach FF1-B, FF1-C, and FF3 (Appendix F & Figure 5), and are labeled as WA (Wetland A) and WB (Wetland B). WA is approximately 5.4 acres in size and WB is approximately 0.28 acres in size. WA is well forested, and WB is under active management for livestock. Vegetation within WA was made up of black willow (Salix nigra), red maple, eastern red cedar, American holly, and sawtooth blackberry. Vegetation within WB was made up of sawtooth blackberry, Pennsylvania smartweed (Persicaria pensylvanica), tearthumb (Persicaria sagittate), soft rush (Juncus effuses), broom sedge (Carex scoparia), and purple stem aster (Symphyotrichum puniceum). A preliminary jurisdictional determination (PJD) request was sent to the USACE on December 8, 2017 and a final PJD has not yet been received (SAW -2017-01466). Wetland forms are included in Appendix F. The US Fish and Wildlife Service (USFWS) National Wetland Inventory Map (NWI) depicts two potential wetland areas within the Project, and these were surveyed during the wetland delineation (Figure 6). Moreover, the soils mapped along reaches FF1 and FF4 are considered predominately hydric, and the soils downstream of the project pond are considered predominantly nonhydric and have the potential to be hydric (Figure 7). Geology According to geology data from the North Carolina Geologic Survey, published in 1985, the Project is located at the boundary of two different map units, OCg and CZma2, both occurring within the Inner Piedmont, Chauga Belt, Smith River Allochthon, and Sauratown Mountain. OCg. This map unit is associated with intrusive rock types of the metamorphosed granitic rock formation that forms in the Paleozoic between 455 and 540 million years ago. This formation is equigranular to megacrystic, foliated to massive; includes Toluca Granite. CZma2. This map unit is associated with metamorphic rocks of the Metagraywacke formation that formed in the later Proterzoic-Paleozoic between 500 and 900 million years ago. This formation contains quartz and microcline porphyroblasts. Soil Survey Existing soil information from the Natural Resource Conservation Service (NRCS) shows the property is located within the Cecil-Appling soil association. This association is deep, well -drained, medium - textured soils found over gneiss, granite, and schist, located on broad, gently rolling ridges. The Yadkin County Soil Survey shows several mapping units across the project. Map units include seven soil series. The soil series found on the Project are described below and summarized in Table 5. Project soil series are mapped by the NRCS as Clifford, Codorus, Dan River sandy loam, Fairview, Hatboro, Rhodhiss-Stott Knob, and Siloam (Figure 7). The Clifford, Fairview, Rhodhiss, and Siloam soils are considered well drained; Codorus soils are somewhat poorly drained; and Hatboro soils are poorly drained. Clifford Sandy Clay Loam. This map unit is found on interfluves and uplands. It formed from saprolite residuum weathered from schist and/or saprolite residuum weathered from gneiss. This map unit is well drained with moderate runoff, moderate permeability, and with no flooding or ponding. Major uses are Green Mesa Mitigation Plan 6 August 2018 row crops, pasture, and forest. Where cultivated, dominant vegetation includes small grains, corn, soybeans, hay, tobacco, and orchards. Where forested, dominant vegetation is Eastern white pine, Virginia pine, red oak, white oak, post oak, hickory, blackgum, red maple, yellow poplar, and dogwood. Codorus Loam. This map unit is found on floodplains and valleys. It formed in recently deposited alluvial materials derived from upland soils materials weathered from mostly metamorphic and crystalline rocks.

The southern portions of the easement have remained forested. A federal flood control pond was built between the northern and southern portions of the easement and was built in 1963. Several watershed characteristics, such as groundwater, vegetation, surface drainage, and potentially soil parameters have been modified. Soil structure and surface texture have been altered from intensive agricultural operations. The Project area is currently still in agricultural use and is being used as pasture for livestock. Livestock have full access to most of the project reaches, and these reaches remain heavily impacted. Outside the Project area is also mostly in agricultural use. The future land use for the Project area will include an established 33.46 -acre conservation easement, that will be protected in perpetuity. The Project easement will have 9,335 linear feet of high functioning streams, a minimum 50 -foot riparian buffer, and will be protected with fencing. Outside the Project will likely remain in agricultural use. 3.4 Regulatory Considerations and Potential Constraints Property, Boundary, and Utilities There are six planned crossings within the Project. These crossings will occur at easement breaks and will allow landowners to continue current land -use and access as needed. There will be two new crossings: a 30 -foot culvert on FF5 and a 70 -foot ford on FF4-A. Four ford crossings are already in place and will be improved. One 30 -foot ford crossing on FF 1-A will be improved; this crossing occurs on an easement break adjacent to the property boundary. One 50 -foot ford crossing on FF2 will be improved; this crossing occurs on an easement break adjacent to the property boundary. One 50 -foot ford crossing on FF3 will be improved. One 30 -foot ford crossing on FF1-C will be improved. There is a powerline easement present at the northern part of the project. The powerline easement crosses the proposed conservation easement in four places and is approximately 70 feet wide (Figure 5). This powerline easement crosses between FF4-A and 17174-13, and FF1-D in three places. There is also an approximate 40 -foot wide utility line to the south of these powerlines that crosses two stream reaches, FF1-C and FF5 (Figure 5). There is a pond present between the project areas. This pond will not be altered, as it is a federal flood control dam, as listed on the USACE National Inventory of Dams (NID) (USACE, 2016). All dams included in the NID consist of dams that meet at least one of the following criteria: high hazard potential classification - loss of human life is likely if the dam fails; significant hazard potential classification - no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns; equal or exceed 25 feet in height and exceed 15 acre-feet in storage; equal or exceed 50 acre-feet storage and exceed 6 feet in height. According to the North Carolina Dam Inventory, this dam is a low hazard (NCDEQ, 2017). The dam was constructed in 1963 and was designed by the USDA NRCS. The dam name is Deep Creek W/S #14 (PL -566; USACE, 2016), it has a height of 26.2 feet, a length of 410 feet, a hydraulic height of nine feet, and a storage capacity of 211 acre-feet. Additional details in reference to this dam can be found in Appendix B. Federal Emergency Management Agency (FEMA)/ Hydrologic Trespass According to the North Carolina Floodplain Mapping Information System, the Project is entirely outside of the FEMA 100 -year flood zone (Zone AE, one percent annual chance of flooding) (Figure Green Mesa Mitigation Plan 9 August 2018 9). No regulated floodway is mapped. Hydraulic modeling will not be required to determine whether restoration activities will have an effect on 100 -year flood elevations downstream. The design and permitting of the mitigation does not require coordination with the Yadkin County Floodplain Administrator, and a No -Rise Certification or CLOMR/LOMR will not be necessary. No hydrologic trespass will be permitted to adjacent properties upstream or downstream of the project. The Project can be found on Flood Insurance Rate Map (FIRM) Panel 4990 (map number 3 7 1 1 0499000J) and Panel 4888 (map number 3710488800J), effective date May 18, 2009. Environmental Screening and Documentation To ensure that a project meets environmental screening, scoping letters were sent to the regulatory agencies of the IRT (Appendix H). Threatened and Endangered Species Plants and animals with a federal classification of endangered or threatened are protected under provisions of Sections 7 and 9 of the Endangered Species Act of 1973 (ESA), as amended. The USFWS database lists one Federally listed species that may occur in proximity to the Project: the Northern long- eared bat (Myotic septentrionalis). No protected species or potential habitat for protected species was observed during preliminary project evaluations. Species and species habitat listed in the USFWS database was inspected during the field investigation to determine whether they occur at the Project. No individual species or habitats were identified on site. Potential impacts to species and habitat off site, downstream, and within the vicinity of the Project were also considered. Formal USFWS consultation for the Northern long-eared bat (NLEB) is not required for this site since it is entirely located outside of the confirmed hibernation and maternity site for the species. Therefore, this Project has met the criteria for the 4(d) rule, and any associated take is therefore exempt. Furthermore, the USFWS encourages tree removal outside the pup season (June 1 to July 31) and/or active season (April 1 to October 31) to reduce the chance of impacting unidentified maternity roosts; and to avoid clearing habitat within a five mile radius of hibernation sites when bats are emerging from or preparing for hibernation (April 1 to May 15 and August 15 to November 14, respectively). The Fish and Wildlife Coordination Act requires consultation with state fish and wildlife agencies when "waters of any stream or other body of water are proposed or authorized, permitted or licensed to be impounded, diverted ... or otherwise controlled or modified." The North Carolina Wildlife Resource Commission (NCWRC) responded to the USACE Public Notice, issued on September 6, 2017, on October 26, 2017. The NCWRC indicated that the old dam structure downstream of the pond may serve as bat habitat and NCWRC biologist may perform bat surveys there in 2018. There hasn't been any update from NCWRC regarding a field investigation to determine if the species is present. Documentation is included in Appendix H. Cultural Resources A review of North Carolina State Historic Preservation Office (SHPO) GIS Web Service (accessed June 11, 2017 and June 13, 2018) database did not reveal any listed or potentially eligible historic or archeological resources on the proposed Project property. There are no documented structures within a half mile of the proposed easement. There are two unlisted features on the Project that the IRT requested further coordination with SHPO. The SHPO has been consulted about these structures. One structure is present on the left bank of FF1- A and is remnants of a stone wall. The second structure is a stone wall crossing on FF1-C and was constructed by the landowner's ancestors. Following consultation, the SHPO recorded these features with the North Carolina Office of State Archaeology as sites 31YD224 (present on reach FF1-A) and Green Mesa Mitigation Plan 10 August 2018 31YD225 (present on reach FF1-C). Since no earthwork or heavy equipment are planned in the immediate vicinity of either site, the proposed mitigation with have no effect. Correspondence with the SHPO is presented in Appendix H. The mitigation treatment on both reaches is Enhancement II and would involve livestock exclusion and riparian buffer planting. Table 6. Regulatory Considerations Regulation Applicable? Resolved?

The easement has six agricultural crossings: one on FF5, one on FF4-A, one on FF3, one on FF1-C, and two are easement breaks adjacent to the property line (FF2 and FF1-A) The stream channels include five unnamed tributaries, split into eleven reaches based on proposed treatment type (Figure 5). Results of the preliminary data collection are presented in Table 7. In general, all or portions of FF 1-A, FF 1-B, FF 1-C, FF 1-D, FF 1-E, F173, F174, and F175 do not function to their full potential; whereas FF2 seems to have functionality and is proposed for preservation only. Current conditions demonstrate significant habitat degradation as a result of impacts from agriculture, livestock production, and lack of riparian buffer. Being heavily eroded and incised, some of the streams do not access their floodplains as frequently as they naturally would have prior to agricultural operations. In the proposed restoration areas, the riparian buffer is in poor condition where much of the riparian buffer is devoid of trees or shrubs and row crops are present up to the edge of the existing channel. In the enhancement areas, trees are present, but understory riparian buffer has been impacted by livestock. Habitat along the majority of the restoration reaches is poor in that there is little woody debris or overhanging vegetation for fish cover or protection for other aquatic species. Morphological parameters are located in Appendix B. Green Mesa Mitigation Plan 11 August 2018 Table 7.

Channel characteristics are summarized in Table 7 and Appendix B. Stream determinations have been verified by the USACE. Discharge Estimating flows (discharge) for the Project is difficult due to the channelization and agricultural impacts of the existing streams. Several models, regression equations, and the Piedmont regional curves were used to estimate existing bankfull discharges. Land use and slope were considered when the discharge calculations were developed. All hydraulic and hydrologic analyses are discussed in Section 6.2. Data and analysis of the hydrologic and hydraulic models are included as Appendix B. Existing Channel Morphology FF1 Reach FF1-A is 1,118 linear feet and begins at the property line in the southwest corner of the Project area and flows east to FF1-B. The reach is sparsely wooded along the channel and has pasture adjacent to the left bank of the channel. Bed material in the channel is primarily bedrock along the upper section of the reach before transitioning to a cobble, gravel, and sand dominated system. There are sections of incised bank areas along the channel. Livestock have access to the entire reach and there is evidence of an old stone dam on this reach. The average channel width is approximately 23 feet with an average depth of approximately one and a half feet. The drainage area for the reach is approximately 498 acres. Reach FF1-B is 922 linear feet and is located in the southern portion of the Project area and flows east into a federal flood control dam. This reach is wooded along the channel and has pasture to the north of the easement. Bed and bank stability is decent throughout the reach. There is obvious evidence of beaver activity at the downstream portion of this reach and riparian wetlands are present. The average channel width is approximately 12 feet with an average depth of approximately nine inches. The drainage area for the reach is approximately 583 acres. Reach FF 1-C is 740 linear feet and begins below the federal flood control dam. The reach flows through an open livestock pasture with minimal tree cover along the channel until tying in with Reach FF1-D. Bed and bank stability are low throughout the reach due to heavy livestock access. A powerline crosses this reach. There is a large intact stone wall on this reach near the downstream end. The average channel Green Mesa Mitigation Plan 12 August 2018 width is approximately 16 feet with an average depth of approximately two feet. The drainage area for the reach is approximately 686 acres. Reach FF1-D is 1,452 linear feet and starts just south of the Baptist Church Road crossing and flows to the east. The reach ultimately drains into Deep Creek. This reach is extremely incised and over - widened. The buffer is devoid of a wooded buffer and has pasture on both sides. Bed and bank stability are low throughout the reach due to heavy livestock access. There is a large powerline that cuts across the stream in multiple locations. The average channel width is approximately 15 feet with an average depth of approximately one foot. The drainage area for the reach is approximately 1,011 acres. Reach FF1-E is 58 linear feet and is the last segment of Reach FF1 on the Project area. The left bank is pasture and the right bank is wooded. This reach for the Project ends at the property boundary. FF2 Reach FF2 is 602 linear feet and located along the southernmost portion of the Project and flows in a northerly direction into reach FF1-B. This reach is wooded on both sides of the channel and does not have livestock access. Bed and bank stability throughout this reach are high. The average channel width is approximately six and a half feet with an average depth of approximately one foot. The drainage area for the reach is approximately 63 acres. FF3 Reach FF3 is 1,943 linear feet and begins at the property line in the southeast portion of the Project area and flows in a northerly direction into a federal flood control dam and riparian wetland area. The entire left bank is wooded, and the right bank has moderate buffer. The reach is adjacent to an actively managed pasture, and historically has served this purpose. There is a current road crossing on this reach. The upstream portion of the reach has signs of bank erosion and instability, while the downstream section is more stable. The average channel width is approximately seven feet with an average depth of around one foot. The drainage area for this section of the reach is approximately 75 acres. FF4 Reach FF4-A is 474 linear feet and begins at the property boundary at the northwest portion of the Project area and flows east toward FF -B. The existing buffer along the upper section is row crop up to the banks of the channel. The upper portion of the reach has bedrock in the channel. The average channel width is approximately eight feet with an average depth of approximately one and a half feet. The drainage area for the reach is approximately 222 acres. Reach FF4-B is 375 linear feet and begins after FF4-A and the powerline easement, and flows east toward FF1-D. After crossing an existing powerline easement, the buffer becomes livestock pasture and active signs of erosion and down -cutting are apparent. The average channel width is approximately eight feet with an average depth of approximately two and a half feet. The drainage area for the reach is approximately 242 acres. FF5 Reach FF5 is 1,631 linear feet and located in the eastern portion of the Project area and flows in a northly direction to FF1-D. The left bank is entirely wooded, and the right bank is moderately wooded and adjacent to an actively managed pasture. Bed and bank stability are good throughout the reach. There is a high density of Chinese privet and black walnut. The average channel width is approximately six feet with an average depth of approximately three inches. The drainage area for the reach is approximately 34 acres. Green Mesa Mitigation Plan 13 August 2018 Channel Stability Assessment A modified version of the channel stability assessment method ("channel assessment") provided in "Assessing Stream Channel Stability at Bridges in Physiographic Regions" by Johnson (2006) was used to assess channel stability for the Project's existing channels. This method may be rapidly applied on a variety of stream types in different physiographic regions having a range of bed and bank materials. The original channel assessment method was designed to evaluate 13 stability indicators in the field. These parameters are: watershed characteristics (frequency of watershed disturbances such as agricultural activities, urbanization, etc.), flow habit, channel pattern, entrenchment/channel confinement, bed material, bar development, presence of obstructions/debris jams, bank soil texture and coherence, average bank angle, bank vegetation/protection, bank cutting, mass wasting/bank failure, and upstream distance to bridge. See Appendix B for a detailed description of the stability indicators. As this method was initially developed to assess stability at bridges, a few minor adjustments were made to remove indicators that contradict stability characteristics of natural channels in favor of providing hydraulic efficiency at bridges. First, the "channel pattern" indicator was altered such that naturally meandering channels scored low as opposed to straightened/engineered channels that are favorable for stability near bridges. Secondly, the last indicator, "upstream distance to bridge", was removed from the assessment as bridges are not a focus of channel stability for this project. The 12 indicators were then scored in the field, and a rating of excellent, good, fair, or poor was assigned to each project reach based on the total score. The channel assessment results (scores and ratings) for the Project are provided in Table 8. Two of the eight project stream reaches received "Good" ratings, one reach received "Excellent" rating, while the remaining five reaches received "Fair" ratings. Most Project streams were observed to have relatively high bank angles and many were found to be actively eroding. A majority of the channels have been impacted by farming practices or livestock production and are slightly entrenched. These characteristics are reflected in the higher channel assessment scores for average bank angle and bank vegetation/protection. Most reaches also scored poorly for watershed characteristics since the surrounding land use is dominated by agriculture activities. Green Mesa Mitigation Plan 14 August 2018 Table 8. Channel Stability Assessment Results ** Excellent (0 < Score <= 36), Good (36 < Score <= 72), Fair (72 < Score <=108), Fair (108 < Score <= 144) Bankfull Verification Bankfull is difficult and often times impossible to accurately identify on actively maintained channels and agricultural ditches. The usual and preferred indicators rarely exist, and other factors may be taken into consideration in order to approximate a bankfull stage. Other factors that may be used are wrack lines, vegetation lines, scour lines, or top of a bankfull bench; however, complete confidence should not be placed on these indicators. Along the proposed restoration reaches, the channel is generally entrenched and actively maintained, which means bankfull indicators were very limited or non-existent. Therefore, bankfull stage was estimated by using Piedmont Regional Curves and other hydrologic analyses, existing cross sections, and in-house spreadsheets to estimate bankfull area and bankfull discharge.

The Framework separates stream functions into five categories, ordered into a hierarchy, which communicate the interrelations among functions and illustrate the dependence of higher level functions (biology, physiochemical and geomorphology) on lower level functions (hydrology and hydraulics). Functions that affect the greatest number of other functions are illustrated at the base of the Pyramid, while functions that have the least effect on other functions are illustrated at the top. The Pyramid is illustrated below Chart 1. Stream Functions Pyramid A Guide for Assessing & Restoring Stream Functions » nvEnvi Ew Chart 1. Stream Functions Pyramid Whdrald a�SS I fEdM-MC §anicscmn IN StreamMechanics Fischenich (2006) found that the most critical functions include those that address hydrodynamic processes, sediment transport processes, stream stability and riparian buffer restoration. By addressing these fundamental functions and processes, a restored stream and riparian system are capable of supporting more dependent functions that typically require time to establish, such as diverse biological communities, chemical and nutrient processes, diverse habitats and improved water and soil quality. The objectives of the Project will address the most critical functional objectives that will allow for a more restored stream and riparian buffer over time. While traditional mitigation approaches have generally relied on surrogate measures of success (i.e. linear feet of restoration) for determining SMU credit yields, a function -based approach provides a Green Mesa Mitigation Plan 19 August 2018 more objective and flexible approach to quantify the expected ecological benefits of a mitigation design. Additionally, a functional based approach broadens the reach -scale goals of a restoration project by contextualizing the functional uplift to the watershed scale. The proposed Project will provide numerous ecological and water quality benefits within the Yadkin River Basin by applying an ecosystem restoration approach. The restoration approach at the reach scale of this project will have the greatest effect on the hydraulic and geomorphology function of the system but will benefit the upper-level functions (physiochemical and biology) over time, and in combination with other projects within the watershed. Anticipated functional benefits and improvements within the Project area, as based on the Function -Based Framework are outlined in Table 9. 4,1 Anticipated Functional Benefits and Improvements Hydrology According to the Stream Functions Pyramid Framework, hydrology is defined as the transport of water from the watershed to the channel. Therefore, this Project intends to make significant improvements to the already functioning hydrology, making it high functioning. Much of the improvement will come from altering land use within these reaches' catchment areas. By converting land -use for a significant percentage of the catchment area from pasture to riparian forest, curve numbers will decrease and reach runoff will improve. Hydraulic The hydraulic function of the Pyramid is defined as transport of water in the channel, on the floodplain, and through sediments. Perhaps the greatest potential uplift at the Project will be achieved through establishing healthy floodplain connectivity. Some of the reaches in the Project do not have functioning floodplain connectivity or stable flow dynamics. Reaches where floodplain connectivity is not - functioning or functioning -at -risk will be improved to functioning by reducing bank height ratios and increasing entrenchment ratios. Reaches in which stable flow dynamics are not -functioning or functioning -at -risk will be improved to functioning by constructing a new channel that is geometrically stable based on the Project's hydrology inputs. Additionally, instream structures will be installed to address the energy and erosive power of the water so that a stable base flow is achieved post -project. Geomorphology Geomorphology as defined within the Pyramid Framework, is the transport of wood and sediment to create bed forms and dynamic equilibrium. Sediment Transport will be improved in reaches that currently function -at -risk or not -functioning by designing channels that transport sediment until it reaches an appropriate place to settle like a point bar. Large Woody Debris Transport and Storage will be improved using woody debris such as log vanes, root wads, log weirs, and log toes for in -stream structures on restoration reaches. The restoration reaches are also designed to accumulate woody debris by having defined shallow riffles where cobble catches and holds woody debris and leaf packs. Riparian vegetation is functioning in some areas but is either functioning -at -risk or not -functioning on most reaches. Therefore, riparian buffers will be planted out to a minimum of 50 feet to improve the riparian vegetation to functioning levels. Bed form diversity will be improved in restoration areas by using a natural riffle pool sequence from the reference reach to inform design of functioning riffle pool sequences in constructed channels based on reference reach conditions. This bed form diversity will also further improve aquatic habitat. These functional parameters are interconnected and ultimately depend on each other in order to function properly. Therefore, by focusing improvements to these parameters, the restored channels will achieve dynamic equilibrium and provide maximum geomorphic functional uplift. Green Mesa Mitigation Plan 20 August 2018 Physiochemical The Pyramid Framework defines the physicochemical category as temperature and oxygen regulation and the processing of organic matter and nutrients. Although this Project would support the overarching goal in the Yadkin Pee -Dee River Basin Priorities to promote nutrient and sediment reduction in agricultural areas, it is difficult to measure nutrient and sediment reduction at this project level because they can be affected by so many variables. However, several restoration actions are known to help reduce nutrients and sediment even though they may not be measurable at the project level. These activities include livestock exclusion and direct removal of fecal inputs, filtering of runoff through buffer areas, the conversion of active farm fields to forested buffers, and improved denitrification and nutrient uptake through buffer zones. Additional benefits may also come from functional uplift of the lower level stream functions (hydraulics and geomorphology), which will reduce sediment and nutrients in the system through bank stabilization and reforesting. Temperature regulation will also be improved through the restoration of canopy tree species to the stream buffer areas. Oxygen regulation will occur through two actions: first, the temperature of the water directly impacts the amount of gas held by the water. Therefore, through planting the buffer to shade the channel the temperature is decreased and dissolved oxygen is increased. Second, the log structures placed in the stream create mixing zones where oxygen dissolves much faster than the standard exchange rate of oxygen to dissolved oxygen. The processing of organic matter will be improved once healthy riffles are shallow enough to catch twigs and branches that then retain leaves. Many of these physiochemical benefits occur slowly over time and are dependent on multiple variables within the stream ecosystem. Therefore, it is not practical or feasible to directly measure these parameters within the monitoring time -frame of this project. With that said, it is logical to use existing riparian buffer and visual performance standards to demonstrate the positive correlation between geomorphic parameters and physicochemical parameters. For example, as riparian buffer trees grow, as represented in annual monitoring reports, it is anticipated that canopy cover is actively shading the stream channel and reducing water temperature. This is not a substitute for direct physicochemical monitoring, but it is a useful tool to help project the long-term benefits of the Project in terms of its functional uplift. Biology The highest category of the Pyramid is biology and is defined as the biodiversity and life histories of aquatic and terrestrial life, specifically referring to animals. As mentioned for the physiochemical stream function, it will be difficult to measure the functional uplift of the biological functions at this site within the monitoring period of the project. However, since the life histories of many species likely to benefit from stream and wetland restoration are depending on all the lower -level functions, the functional uplift from the hydraulic and geomorphic levels would have a positive effect to the biology over time and in combination with other projects within the watershed is anticipated. Again, there is no substitute for direct biological monitoring, but it is important to understand the hierarchy of the Stream Functions Pyramid Framework in order to help project long-term benefits of the Project though only categories two and three (hydraulics and geomorphology) will be directly measured during the seven- year monitoring period. Green Mesa Mitigation Plan 21 August 2018 5 MITIGATION PROJECT GOALS AND OBJECTIVES Through the comprehensive analysis of the Project's maximum functional uplift using the Stream Functions Pyramid Framework, specific, attainable goals and objectives will be realized by the Project. These goals clearly address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2009 Upper Yadkin Pee -Dee River RBRP. The Project will address outlined RBRP Goals 1 and 6 (listed in Section 2). The Project goals are: • Improve water transport from watershed to the channel in a non-erosive manner in a stable channel; • Improve flood flow attenuation on site and downstream by allowing for overbank flows and connection to the active floodplain; • Improve instream habitat; • Restore and enhance native floodplain vegetation; and • Indirectly support the goals of the 2009 Upper Yadkin Pee -Dee RBRP to improve water quality and to reduce sediment and nutrient loads. The Project objectives to address the goals are: • Design and construct stable stream channels with appropriate pattern, dimension, and profile based on reference reach conditions; • Add in -stream structures and bank stabilization measures to protect restored and enhanced streams; • Install habitat features such as brush toes, constructed riffles, woody materials, and pools of varying depths to restored and enhanced streams; • Reduce bank height ratios and increase entrenchment ratios to reference reach conditions; • Increase forested riparian buffers to at least 50 feet on both sides of the channel along the project reaches with a hardwood riparian plant community; • Treat exotic invasive species; • Establish a permanent conservation easement on the Project that will exclude future livestock from stream channels and their associated buffers. Anticipated functional uplift, benefits, and improvements within the Project area, as based on the Function Based Framework are outlined in Table 9. Limitations to achieving these watershed goals arise by remaining constrained to the project boundaries. While we are restoring the habitat and streams to stable and effective conditions that achieve our goals within the Project parcels, we are unable to influence the effect of poor riparian buffers and livestock impact in other areas within the watershed. However, the overall watershed functionality and health will improve to meet the RBRP goals. Best Management Practices (BMPs) A suite of agricultural BMPs will be utilized for the Project to reduce direct effluent inputs, pollutant contamination, and sediment loading. The combination of the following agricultural BMPs: riparian buffer planting, bank stabilization, stream restoration, livestock exclusion, livestock watering facilities, and pipeline, will ultimately lead to the functional uplift of the site, while still allowing livestock production to persist through the installation of alternative water sources. Green Mesa Mitigation Plan 22 August 2018 The riparian buffer will be restored along all project reaches, except some of the enhancement reaches and preservation reach. Restored riparian buffers are established adjacent to and up -gradient from watercourses of water bodies to improve water quality. The main advantages of the restored riparian buffer will be to provide water quality treatment, erosion control, and water temperature benefits. Moreover, there will be significant reductions in sedimentation, nutrient input, and fecal coliform input. Approximately 12,00 linear feet of livestock exclusion fencing will be installed along the easement boundary; therefore, livestock will no longer have stream access. The type of exclusion fence installed will be based on landowner preference. The main advantages of exclusion fence are that there will be significant reductions in sediment, nutrients, and fecal coliform. To account for eliminating livestock water access, landowners will be provided an alternate water source. Three new wells will be installed, and up to 12 watering facilities will be installed, along with the associated pipeline to supply high quality drinking water to livestock.

Portions of the Project were historically diverted to form poorly -functioning stream channels. Physical parameters of the Project were used, as well as other reference materials, to determine the target stream type. The "Classification of the Natural Communities of North Carolina" was also used to narrow the potential community types that would have existed at the Project (Schafale, 2012). An iterative process was used to develop the final information for the Project design. Targeted reference conditions included the following: • Located within the Physiographic Region and ecoregion, • Similar watershed size, • Similar land use on site and in the watershed, • Similar soil types on site and in the watershed, • Ideal, undisturbed habitat — several types of woody debris present, • Similar topography, • Similar slope, • Pattern common among Piedmont streams, and • Minimal presence of invasive species. Obtaining property owner information and owner authorization for access was another factor in locating suitable reference sites for the Project. There was no predetermined amount of reference sites needed as long as the site was suitable and met the parameters. Many streams in this watershed are impacted by cattle and agricultural practices, having a minimal riparian buffer, making it difficult to find an ideal reference for the Project site. Parts of reference stream parameters for the site proves to be ideal in both geomorphology and habitat is located just upstream of the preservation Reach FF2 as well as off-site reference reaches UT to Mill Creek and UT to Grassy Creek. Reference Watershed Characterization The first reference reach, UT to Mill Creek, is also located within the Yadkin Pee -Dee River Basin. This reach is 225 feet in length, with a drainage area of 1.44 square miles (921 acres). The land use is characterized by mostly forest (64%), herbaceous/shrub (27%), and a small amount of cultivated land. The second reference reach, UT to Grassy Creek, is also located within the Yadkin Pee -Dee River Basin. This reach is 318 feet in length, with a drainage area of 0.67 square miles (426 acres). The land use is characterized by mostly agricultural, with mixed pines and hardwoods, and a small amount of residential Reference Discharge Several hydrologic models/methods were used to develop a bankfull discharge for each reference reach. Existing drainage area, land use, slope, roughness, and cross-sectional area were all factors considered when performing the calculations. Using a combination of regional curves, in-house spreadsheet tools, and a project specific regional flood frequency analysis, the existing bankfull discharge for the references reaches was estimated at 113-122 cubic feet per second (ft3/s) and 50 cubic feet per second for UT to Mill Creek and UT to Grassy Creek respectively. See Section 6.2 for a more detailed description of the hydrologic analyses performed for this project. Green Mesa Mitigation Plan August 2018 25 Reference Channel Morphology In comparison to the restoration reaches, both the onsite reference reach and the UT to Mill Creek and UT to Grassy Creek reaches are similar is basin size and basin characteristics. When comparing pattern, dimension and profile, dimensionless ratios were computed for proper scaling to the design based on on-site verified bankfull widths. The designed reach would then have the necessary dimensions of either a smaller or larger stream corresponding to differences in drainage area. The onsite reference reach for FF4-B was typically 12-14 feet wide and 1.5 feet deep. The cross sectional area was typically around 15.6 square feet with a width to depth ratio around 9.0. For Reach FF1-D, the reach was typically 12- 16 feet wide and 2.3 feet deep. The cross sectional area was typically around 27-34 square feet with a width to depth ratio around 8.0. For Reach FF5 the Channel Slope (S) versus Pool to Pool Spacing to Bankfull Riffle Width (Ps/Wbkf) was used for the step pool system.

Typical cross-sections for all reaches within the Project were collected and analyzed for bankfull area, width, depth and discharge. The cross-sections were plotted against the Piedmont Regional Curves for verification and analysis along with the hydrologic analysis. Evidence that can further support the location of bankfull is the lack of any bench or berm features within the channel, and wrack lines present within the floodplain. Based on the analysis, the data collected lined up with in the 95% confidence interval for the cross-sectional area further lowering the uncertainty in the proposed design bankfull area.

On June 21, 2018 one 100m2 plot was surveyed along Reach FF2, to categorize the existing vegetation community. Forested riparian areas along the reference reach have not been heavily disturbed and remain relatively intact. Project vegetation included tulip -poplar (Liriodendron tulipifera), white oak, sourwood, red maple, American holly, black tupelo, American beech, pignut hickory, flowering dogwood, eastern red cedar, black walnut, American sycamore, and black cherry. The average basal area was approximately 4.77m2 per hectare, and the average stems per -acre was 202 stems/ac. There was a high species diversity in the herbaceous stratum, including: Christmas fern, Virginia creeper, little heartleaf, wild yam, American hog peanut, common blue violet, sessileleaf bellwort, yellow star grass, white lettuce, New York fern, devil's grandmother, strawberry bush, spear leaved violet, frostweed, long leaved bluet, Cinquefoil, ebony spleenwort, white snake root, j ewelweed. Some invasive species we present at the reference reach, most notably Chinese privet and Japanese honeysuckle. It is anticipated that a local seed source for high dispersal species is present upstream at the Project and will disperse across much of the Project area. These species are often found in early successional communities and quickly fill disturbance gaps. Because many of these high dispersal species often become aggressive in these sites, they are not included in the Restoration Planting List (Section 6.3). Hardwood species typical of the target community were observed in adjacent and nearby communities and were judged to be more appropriate for this site. 6.2 Design Parameters Stream Restoration Approach Stream restoration efforts along the tributaries of the Project will be accomplished through analyses of geomorphic conditions and watershed characteristics. The design approach applies a combination of analytical and reference reach based design methods that meet objectives commensurate with both ecological and geomorphic improvements. Proposed treatment activities may range from minor bank Green Mesa Mitigation Plan August 2018 27 grading and planting to re-establishing stable planform and hydraulic geometry. For reaches requiring full restoration, natural design concepts have been applied and verified through rigorous engineering analyses and modeling. The objective of this approach is to design a geomorphically stable channel that provides habitat improvements and ties into the existing landscape. The Project will include priorities I and II stream restoration, enhancement 1, enhancement 11, enhancement 111, and preservation. Stream restoration will incorporate the design of a single -thread meandering channel, with parameters based on data taken from reference sites, published empirical relationships, regional curves developed from existing project streams, and NC Regional Curves. Analytical design techniques will also be a crucial element of the project and will be used to determine the design discharge and to verify the design as a whole. A conceptual plan view is provided in Figure 10. Current stream conditions along the proposed restoration reaches exhibit habitat degradation as a result of impacts from livestock and channelization performed to promote agricultural activities. Additionally, the riparian buffer is in poor condition throughout the sections of FF4-B and parts of FF1-D, where much of it is devoid of trees or shrubs, and active pasture is present up to the edge of the existing channel. The Project design approach began with a thorough study of existing conditions, including the onsite streams, valleys, and watershed. Design parameters, including active channel, habitat and floodplain features were developed from analyses performed on the reference site data. Analytical design techniques were used to determine the design discharge and to verify the design as a whole. Geomorphic and habitat studies will be performed concurrently with the engineering analyses. While stream design will be verified by simulations of hydrology and fluvial processes, analogs of desirable habitat features will be derived from reference sites and integrated into the project design. Both in - stream and riparian habitat features will be designed. In -stream structures will be used throughout the project to act as grade control and for bank stabilization by dissipating and redirecting the stream's energy. Bank stability may further be enhanced through the installation of brush mattresses, live stakes and cuttings bundles. Sections of abandoned stream channel will be backfilled with material excavated from on site to the elevation of the floodplain in areas adjacent to the new channel, installing channel plugs where necessary. The floodplain will be planted with native species creating a vegetated buffer, which will provide numerous water quality and ecological benefits. Stream banks will be stabilized using a combination of grading, erosion control matting, bare -root plantings, native material revetment techniques (i.e., bioengineering) and structure placement. The stream and adjacent riparian areas will be protected by a minimum 50 -foot conservation easement (where feasible) which will be fenced to exclude livestock as needed. The Project has been broken into the following design reaches: Reach FF1-A - This reach begins on the southwest end of the project, flows east to FF1-B, and totals 1,118 linear feet of Enhancement II. Sparse woodland is located on the left bank, and actively managed pasture lies just outside of the wood line. Enhancement activities will include improving habitat through riparian buffer planting and livestock exclusion. While there are areas for spot stabilization, this is the best approach based on the amount of bedrock in this reach. Moreover, this reach will have riparian buffers wider than the 50 -foot minimum and up to 125 -feet in some places. Green Mesa Mitigation Plan August 2018 28 Reach FF1-B - This reach begins on the southwest end of the project from FF1-A, flows east to an impoundment, and totals 922 linear feet of Enhancement III. Enhancement activities will include improving habitat through supplemental planting, protection of fringe wetlands, livestock exclusion, and beaver removal. Moreover, this reach will have riparian buffers wider than the 50 -foot minimum, and up to 150 -feet in some places. Reach FFl-C —This reach begins downstream of the impoundment that FF 1-B flows into. This reach flows north to FF1-D. This reach totals 740 linear feet of Enhancement II. This reach is broken up into multiple sections due to the presence of a powerline easement and an existing agricultural crossing. Actively managed pasture is located adjacent to the reach. Enhancement activities will include improving habitat through buffer plantings and livestock exclusion fencing. Minimal bank grading and buffer re-establishment is also proposed along this reach. There is a large stone wall intact on this reach that will remain in place. The restoration of the riparian areas and buffers along this reach will filter runoff from adjacent pasture, reduce sediment loads, and provide wildlife corridors throughout the Project area. Reach FF1-D - This reach begins on the north end of the project, just downstream of Baptist Church Road and Reach FF4-B and totals 1,391 linear feet of Restoration. Actively managed pasture is located adjacent to the reach. Restoration activities will include constructing anew channel within the natural valley with appropriate dimensions and pattern and backfilling the abandoned channel. In -stream structures such as constructed riffles, brush toes, boulder riffles, and j -hooks will be installed for stability and to improve habitat. Habitat will further be improved through buffer plantings, livestock exclusion, and invasive species treatment. Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. There are four easement breaks along this reach to account for crossings associated with a Duke Power transmission line and a telephone line. The riparian buffer will be less than the minimum 50 -feet due in some locations due to the presence of the aforementioned utility lines and their rights-of-way. However, there are also portions of the buffer that exceed the minimum 50 -feet and reach up to 125 - feet in width in some areas. Reach FF1-E - Reach FF1-E is 59 linear feet and is last segment of Reach FF1 on the Project. The left bank is pasture and the right bank is wooded. This reach for the Project ends at the property boundary. Reach FF2 - This reach begins on the south end of the project, flows north to FF1-B. This reach totals 602 linear feet of Preservation. Dense woodland is located adjacent to the bedrock controlled reach. Preservation activities will include improving habitat through livestock exclusion fencing. The livestock exclusion fencing will provide wildlife corridors throughout the Project area and will remove livestock access to the riparian areas. Moreover, this reach will have riparian buffers wider than the 50 - foot minimum, and up to 75 -feet in some places. Reach FF3 - This reach begins on the south end of the project and flows north to the pond impoundment on site. The totals 1,943 linear feet of Enhancement III. Enhancement activities will include improving habitat through livestock exclusion, invasive species treatment, and supplemental buffer planting. The downstream section of this reach will be enhancing wetland areas, but no credit for wetlands is being claimed. The livestock exclusion fencing will provide wildlife corridors throughout the Project area and will remove livestock access to the riparian areas. Moreover, this reach will have riparian buffers wider than the 50 -foot minimum, up to 150 -feet in some places. Reach FF4-A — This reach begins on the west end of the project, and flows southeast to FF4-B. This reach totals 474 linear feet of Enhancement I. Actively managed pasture is present on both sides of the reach. Enhancement activities will include improving habitat through livestock exclusion, buffer Green Mesa Mitigation Plan August 2018 29 plantings, and the installation of in -stream structures such as log sills and brush toes. Additional enhancement activities will include constructing a floodplain bench along the right bank and laying back the left bank at the upstream end of the reach. Moreover, this reach exceeds the 50 -foot minimum buffer requirement on the left bank. Reach FF4-B - This reach begins on the west end of the project at a power line easement break just downstream of reach FF4-A and flows east to Baptist Church Road. This reach totals 444 linear feet of restoration and begins at the bedrock section. Actively managed pasture is present on both sides of the reach. Restoration activities will include constructing a new channel within the natural valley with appropriate dimensions pattern and backfilling the abandoned channel. Native bed material will be harvested when possible. In -stream structures such as constructed riffles, brush toes, boulder riffles, and j -hooks will be installed for stability and to improve habitat. Habitat will further be improved through buffer plantings and livestock exclusion. Proposed buffer activities will improve riparian areas that will filter runoff from adjacent pastures, thereby reducing nutrient and sediment loads to the channel. Moreover, portions of this reach will have riparian buffers wider than the 50 -foot minimum, up to 125 -feet in some places. Reach FF5 -This reach begins on the southeast end of the project and flows north to FF 1-D. This reach totals 1,586 linear feet of Enhancement III and 56 linear feet of restoration at the tie-in with FF1-D. Woodland and actively managed pasture is located adjacent to the reach. Enhancement activities will include improving habitat through livestock exclusion, invasive species treatment, removal of approximately 90 percent of the black walnut stems, and buffer planting in areas where black walnut has been removed. Planted stems along FF5 will be black walnut tolerant; these species are indicated on the planting plan (K -State Research and Extension, 2015). Moreover, this reach will have riparian buffers wider than the 50 -foot minimum. Design Methods There are three primary methods that have demonstrated success in stream restoration: analog, empirical, and analytical. All three methods have advantages and limitations, and it is often best to utilize more than one method to address site-specific conditions or to verify the applicability of design elements. This is particularly true in developed watersheds where existing conditions do not always reflect current inputs and events, and sediment and hydrologic inputs may remain unstable for some time. Combinations of analytical, empirical, and analog methods were used to develop the stream designs for the Project. Analytical Approach Analytical design is based on principles and processes considered universal to all streams and can entail many traditional engineering techniques. The analytical approach utilizes continuity, roughness equations, hydrologic and hydraulic models, and sediment transport functions to derive equilibrium conditions. Because the Project is located within a rural watershed, restoration designs are based on hydrologic and hydraulic analyses, including rainfall -runoff models to determine design discharges coupled with reference reach techniques. Analog Approach The analog method of natural channel design involves the use of a "template" or reference stream located near the design reach and is particularly useful when watershed and boundary conditions are similar between the design and analog reaches (Skidmore et al., 2001). In an analog approach, the pattern, dimension, and profile are used to inform design parameters for the subject stream. Green Mesa Mitigation Plan August 2018 30 Empirical Approach Empirical design is based on regional mathematical relationships among measured channel variables. The flood frequency analysis and regional curve evaluation described above are examples of empirical design methods to select a range of channel forming discharges for a given watershed area. Typical Design Sections Typical cross sections for riffles and pools are shown on the design plan sheets in Appendix A. The cross-section dimensions were developed for the three design reaches by using an in-house spreadsheet described in Section 6.2 of this report. The cross sections were altered slightly to facilitate constructability; however, the cross-sectional area, width to depth ratio, and side slopes were preserved. Typical pool sections include pools located on straight reaches and pools on meander bends. Meander Pattern The design plans showing the proposed channel alignment are provided in Appendix A. The meander pattern was derived directly from the analog reach and was altered in some locations to provide variability in pattern, to avoid on site constraints, to follow the valley pattern, and to make the channel more constructible. The morphologic parameters summarized in the Appendix B were applied wherever these deviations occurred. Longitudinal Profiles The design profiles are presented in Appendix A. These profiles extend throughout the entire project for the proposed channel alignment. The profiles were designed using the analog reach bed features as a template for feature lengths and slopes. The bed slopes and bankfull energy gradients were determined for each design reach based on the existing valley slope and the sinuosity of the design reach. Log and rock structures will be utilized in the design to control grade, divert flows, and provide additional habitat diversity and stability. In -Stream Structures Structures will be incorporated into the channel design to provide additional stability and improve aquatic habitat. Native materials and vegetation will be used for revetments and grade control structures where applicable. Additionally, log and rock structures will be utilized intermittently along all reaches to provide increased stability and habitat. Typical rock structures that will protect the channel bed and/or banks will include riffle grade controls and cross -vanes. Woody debris will be placed throughout the channel at locations and at a frequency that is similar to those observed in the analog reaches. Woody habitat features installed will include root wads, brush toes, and log vanes. Other bank stability measures include the installation of coir matting along stream banks, live stakes, log sills, and log toes. Typical details for proposed in -stream structures and revetments are in Appendix A. Data Analysis Design Discharge Based upon the hydrologic analyses described below, design discharges were selected that fall between model results for the 1.1 -year and 1.5 -year flood frequency analysis for each reach. The selected flows for the restoration reach FF4-B is 50 ft'/s, 15 ft3/s for FF5-B and 125 ft3/s for FF1-D. These discharges will provide frequent inundation of the adjacent floodplain. The design discharges were selected based on the following rationale: • The calculated bankfull discharge for the analog/reference reach and existing reaches fall between the results of the 1.1 -year and 1.5 -year flood frequency analysis, Green Mesa Mitigation Plan August 2018 31 The results of the 1.1 -year flood frequency analysis are slightly higher than the NC regional curve (Doll et al., 2002), and Selecting design discharges slightly higher than the 1.1 -year storm events allows frequent inundation of the adjacent floodplain. Stream Hydrologic Analysis Hydrologic evaluations were performed for the design reaches using multiple methods to determine and validate the design bankfull discharge and channel geometry required to provide regular floodplain inundation. The use of various methods allows for comparison of results and eliminates reliance on a single model. Peak flows (Table 10) and corresponding channel cross sectional areas were determined for comparison to design parameters using the following methods: • Regional Flood Frequency Analysis, • NC and VA Regional Curves for the Rural Piedmont, and • USGS regional regression equations for rural conditions in the Blue Ridge -Piedmont. Regional Flood Frequence A flood frequency analysis was completed for the study region using historic gauge data on all nearby USGS gauges with drainage areas less than 6,400 acres (10 mit) which passed the Dalrymple homogeneity test (Dalrymple, 1960). This is a subset of gauges used for USGS regression equations. Regional flood frequency equations were developed for the 1.1-, 1.5-, and 2 -year peak discharges based on the gauge data. Discharges were then computed for the design reach. These discharges were compared to those predicted by the discharge regional curve and USGS regional regression 2 -year discharge equations. Regional Curve Regression Equations The North Carolina Piedmont regional curves by Harman et al. (1999) and Doll et al. (2002) and the Virginia Rural Piedmont regional curves by Lotspeich (2009) for discharge were used to predict the bankfull discharge for the Project. The NC regional curves predicted flows that are similar to those predicted by the 1.1 -year flood frequency, while the VA curves are comparable to flows predicted by the 1.5 -year flood frequency equation. The regional curve equations for NC discharges by Doll et al. (2002): (1) Qbkj�=89.04*(DA)033 (Harman et al., 1999) (2) Qbkj=91.62*(DA)0_71 (Doll et al., 2002) (3) Gbk= 43.895*(DA)0.9472 (Lotspeich, 2009) Where Qbkf=bankfull discharge (ft3/s) and DA=drainage area (mit) USGS Regional Regression Equations USGS regression equations estimate the magnitude and frequency of flood -peak discharges. The regression equations were developed from gauge data in different physiographic regions of the Southeastern United States. For this analysis, there was only concern for the 2 -year return interval. The equation for the rural Piedmont/Foothills (Hydrologic Region 1) (4) is: (4) Q2=158*(DA)0.649 Green Mesa Mitigation Plan August 2018 32 Table 10.

Typically, sediment transport is assessed to determine a stream's ability to move a specific grain size at specified flows. Various sediment transport equations are applied when estimating entrainment for sand and gravel bed streams found in the piedmont. The US Army Corps of Engineers (USAGE) report, Stability Thresholds for Stream Restoration Materials (Fochenich, 2001), was used to obtain permissible shear stresses and velocities. Data found in this document was obtained from multiple sources using different testing conditions. The following methods and published documents were utilized during the sediment transport analysis: • Permissible Shear Stress Approach, and • Permissible Velocity Approach. Shear Stress Approach Shear stress is a commonly used tool for assessing channel stability. Allowable channel shear stresses are a function of bed slope, channel shape, flows, bed material (shape, size, and gradation), cohesiveness of bank materials, vegetative cover, and incoming sediment load. The shear stress approach compares calculated shear stresses to those found in the literature. Shear stress is the force exerted on a boundary during the resistance of motion as calculated using the following formula: (1) i = yRS T = shear stress (lb/ft') y = specific gravity of water (62.4 lb/ft') R = hydraulic radius (ft) S = average channel slope (ft/ft) Table 11. Comparison of Allowable and Proposed Shear Stresses '(Fischenich, 2001) Review of the above table shows that the proposed shear stresses for the Project design reaches fall between the critical shear stress (shear stress required to initiate motion) and the allowable limits. Therefore, the proposed channel should remain stable. Green Mesa Mitigation Plan August 2018 33 Allowable Shear Stress' Proposed Shear Stress at Critical Shear Stress Reach Bankfull Stage (lbs/ft') (lbs/ft2) Coarse Gravel Cobble Vegetation (lbs/ft2) (lbs/ft2) (lbs/ft) 0.74 >0.54 0.33 to 0.67 0.67 to 2.0 0.7 to 0.1.7 17175-13 1.32 >0.54 0.33 to 0.67 0.67 to 2.0 0.7 to 0.1.7 FF1-D 0.58 >0.54 0.33 to 0.67 0.67 to 2.0 0.7 to 0.1.7 '(Fischenich, 2001) Review of the above table shows that the proposed shear stresses for the Project design reaches fall between the critical shear stress (shear stress required to initiate motion) and the allowable limits. Therefore, the proposed channel should remain stable. Green Mesa Mitigation Plan August 2018 33 Velocity Approach Published data are readily available that provide entrainment velocities for different bed and bank materials. A comparison of calculated velocities to these permissible velocities is a simple method to aid in the verification of channel stability. Table 12 compares the proposed velocities calculated using Manning's equation with the permissible velocities. Table 12. Comparison of Allowable and Proposed Velocities Manning's "n" Design Velocity Permissible Velocity' Reach Value (ft/s) Bed Material (ft/sec) FF4-13 0.04 2.9-3.2 Coarse gravel to cobble 2.5-7.5 17175-13 0.04 3.8-4.7 Coarse gravel to cobble 2.5 - 7.5 FF1-D 0.04 2.7-3.0 Coarse gravel to cobble 2.5 -7.5 '(Fischenich, 2001) Sediment Supply In addition to the stability assessment, a qualitative analysis of sediment supply was performed by characterizing watershed conditions. A combination of field reconnaissance and windshield surveys, existing land use data, and historical aerial photography were analyzed to assess existing and past watershed conditions to determine if any changes occurred that would significantly impact sediment supply. As discussed in Section 3.3, the land use throughout the site has changed little over the past 60 years, with much of the project area being used primarily for agricultural purposes. Much of the forested areas are located within the southern portions of the project reaches. Land use has remained relatively constant within this rural watershed, and significant land disturbing activities are not anticipated for the future. Observations and assessments of these reaches upstream and/or in the preservation reaches show little signs of aggradation (deposition) or degradation, and that the streams appear physically stable. This indicates the reaches are able to effectively transport the sediment supplied by their respective watersheds. There are several localized areas of instability and erosion along the channels, which appear to be a result of livestock activity and agricultural activities occurring up to and along channel banks and not from watershed activities. It is anticipated that sediment supply from agricultural land adjacent to the project will decrease as buffers are enhanced and widened, and flow from existing agricultural ditches will be diffused before entering the proposed channel. Since little deposition or degradation (scour) was observed along the restoration reaches, it appears that the channels are able to effectively move the sediment supplied from the surrounding watershed. Because observed areas of degradation can be attributed to farming practices adjacent to the channel and not watershed activities, a threshold channel design approach was used. This approach assumes minimal movement (vertical or lateral migration) of the channel boundary during design flow conditions, and that the channel is not sensitive to sediment supply. Additionally, grade controls have been integrated throughout the design to provide vertical stability in the event scour should occur. 6.3 Vegetation and Planting Plan Plant Community Restoration The restoration of the plant communities is an important aspect of the restoration project. The selection of plant species is based on what was observed at the reference reach, species present in the forest Green Mesa Mitigation Plan August 2018 34 surrounding the restoration site, and what is typically native to the area. Several sources of information were used to determine the most appropriate species for the restoration project. The reference stream is located within an intact Piedmont Headwater Stream Forest community. Dominant tree species included tulip -poplar, white oak, sourwood, red maple, American holly, black tupelo, American beech, pignut hickory, flowering dogwood, eastern red cedar, black walnut, American sycamore, and black cheery. The reference site was chosen due to the stability of the channel, the physical structure of the forest community, and to evaluate stream habitat. A Piedmont Alluvial Forest will be the target community along all project reaches and will be established to include a diverse mix of species. These target communities will be used for the planting areas within the project, shown in Appendix A. The plant species list has been developed and can be found in Table 13. Specifically, along FF5 species targeted for planting will be black walnut tolerant (K -State Research and Extension, 2015). Species with high dispersal rates are not included because of local occurrence, adjacent seed sources, and the high potential for natural regeneration. The high dispersal species include red maple, tulip poplar, and sweetgum. The restoration of plant communities along the Project will provide stabilization and diversity. For rapid stabilization of the stream banks (primarily outside meanders), silky dogwood (Cornus amomum) and black willow (Salix nigra) were chosen for live stakes along the restored channel because of their rapid growth patterns and high success rates. Willows grow at a faster rate than the species planted around them, and they stabilize the stream banks. Willows will also be quicker to contribute organic matter to the channel. When the other species are bigger, the black willows will slowly stop growing or die out because the other species would outgrow them and create shade that the willows do not tolerate. The live stake species will be planted along the outside of the meander bends three feet from the top of bank, creating a three-foot section along the top of bank. The live stakes will be spaced one per linear foot with alternate spacing vertically. Green Mesa Mitigation Plan August 2018 35 Table 13.

Invasive species will require different and multiple treatment methods, depending on plant phenology and the location of the species being treated (Appendix G). All treatment will be conducted as to maximize its effectiveness and reduce chances of detriment to surrounding native vegetation. Treatment methods will include mechanical (cutting with loppers, clippers, or chain saw) and chemical (foliar spray, cut stump, and hack and squirt techniques). Plants containing mature, viable seeds will be removed from the Project and properly disposed. All herbicide applicators will be supervised by a certified ground pesticide applicator with a North Carolina Department of Agriculture and Consumer Services (NCDA&CS) license and adhere to all legal and safety requirements according to herbicide labels, and NC and Federal laws. Management records will be kept on the plant species treated, type of treatment employed, type of herbicide used, application technique, and herbicide concentration and quantities used. These records will be included in all reporting documents. Soil Restoration After construction activities, the subsoil will be scarified and any compaction will be deep tilled before the topsoil is placed back over the Project. Any topsoil that is removed during construction will be stockpiled and placed over the Project during final soil preparation. This process should provide favorable soil conditions for plant growth. Rapid establishment of vegetation will provide natural stabilization for the Project. Green Mesa Mitigation Plan August 2018 36 6.4 Mitigation Summary Natural channel design techniques have been used to develop the restoration designs described in this document. The combination of the analog and analytical design methods was determined to be appropriate for this Project because the watershed is rural, the causes of disturbance are known and have been abated, and there are minimal infrastructure constraints. The original design parameters were developed from the measured analog/reference reach data and applied to the subject stream. The parameters were then analyzed and adjusted through an iterative process using analytical tools and numerical simulations of fluvial processes. The designs presented in this report provide for the restoration of natural Piedmont gravel -bed channel features and stream bed diversity to improve benthic habitat. The proposed design will allow flows that exceed the design bankfull stage to spread out over the floodplain, restoring a portion of the hydrology for the existing wetlands. A large portion of the existing stream will be filled using material excavated from the restoration channel. However, many segments will be left partially filled to provide habitat diversity and flood storage. Native woody material will be installed throughout the restored reach to reduce bank stress, provide grade control, and increase habitat diversity. Forested riparian buffers of at least 50 feet on both sides (when feasible) of the channel will be established along the Project reach. An appropriate riparian plant community (Piedmont Alluvial Forest) will be established to include a diverse mix of species. within the Project. The plant species list has been developed and can be found in Table 13. Replanting of native species will occur where the existing buffer is impacted during construction. Due to the nature of the project, complete avoidance of stream and wetland impacts is not possible. Proposed stream impacts, including stream relocation and culverts, will be replaced on site. Wetland impacts associated with restoration and enhancement efforts will only temporarily impact wetlands and will provide an overall increase in wetland function with the addition of native trees and shrubs along the stream banks, and restored hydrology. All stream impacts will be accounted for in the Pre - Construction Notification (PCN) form. 6.5 Determination of Credits Mitigation credits presented in Table 14 are projections based upon site design (Figure 10). Upon completion of site construction, the project components and credits data will only be revised to be consistent with the as -built condition if there is a large discrepancy and with an approved mitigation plan addendum. This will be approved by the USACE. Green Mesa Mitigation Plan August 2018 37 Table 14. Mitigation Credits *SMUs are adjusted in accordance with Section XI(C)- "Wilmington District Stream Buffer Credit Calculator", supplied to Providers in the January 2018, from the USA CE. A detailed description of the methodology and calculations is described below and in Figure(s) 11. 6.6 Credit Calculations for Non -Standard Buffer Widths Buffer measurements for additional credit were made horizontally, beginning from the edge of the wetted perimeter and extending to easement boundary. Due to the minimum required widths, additional credit was not generated until a stream is at least 50 feet inside the edge of the buffer. Table 15 describes the adjustments in stream credit based on buffer widths. Areas within the project that are being used to generate additional credit are solely being used for the generation of stream mitigation credits and will not be used for the generation of any other credit type (i.e., the same square foot of buffer cannot be used to generate wetland credit, nutrient offset credits or state buffer credits).

To perform this calculation GIS analysis was performed to determine the area (in square feet) of ideal buffer zones and actual buffer zones around all streams within the project. Minimum standard buffer widths are measured from the top of bank (50 feet in Piedmont and Coastal Plain counties or 30 feet in mountain counties) and do not generate additional credit. The ideal buffers are the maximum potential size (in square feet) of each buffer zone measured around all creditable stream reaches, calculated using GIS, including areas outside of the easement. The actual buffer is the square feet in each buffer zone, as measured by GIS, excluding non -forested areas, all other credit type (e.g., wetland, nutrient offset, buffer), easement exceptions, open water, areas failing to meet the vegetation performance standard, etc. Additional credit is given to 150 feet in buffer width, so areas within the easement that are more than 150 feet from creditable streams should were not included in this measurement. Non -creditable stream reaches within the easement are removed prior to calculating this area with GIS (for both ideal and actual). The stream lengths, mitigation type, ideal buffer, and actual buffer are all entered into the calculator. This is data is processed, and the resulting credit amounts are totaled for the whole project (Table 14, Figure 11, Appendix B). Green Mesa Mitigation Plan August 2018 39 7 PERFORMANCE STANDARDS The success criteria for the Project will follow accepted and approved success criteria presented in the 2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation Update and subsequent agency guidance. Specific success criteria components are presented below. 7.1 Stream Restoration Success Criteria Bankfull Events Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull events have been documented in separate years. Crest gauges will be installed FF1-D and FF4-B. Cross Sections There should be little change in as -built cross sections. If changes do take place, they should be evaluated to determine if they represent a movement toward a less stable condition (for example down - cutting or erosion) or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross sections shall be classified using the Rosgen stream classification method, and all monitored cross sections should fall within the quantitative parameters defined for channels of the design stream type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 1.4 within restored reaches. Channel stability should be demonstrated through a minimum of four bankfull events documented in the seven-year monitoring period. Digital Image Stations Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should not indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A series of images over time should indicate successional maturation of riparian vegetation. 7.2 Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the Project will follow IRT Guidance. The interim measures of vegetative success for the Project will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3, five-year old trees at seven feet in height at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre with an average height of ten feet at the end of Year 7. Volunteer trees will be counted, identified to species, and included in the yearly monitoring reports, but will not be counted towards the success criteria of total planted stems. Moreover, any single species can only account for up to 50 percent of the required number of stems within any vegetation plot. Any stems in excess of 50 percent will be shown in the monitoring table, but will not be used to demonstrate success. Supplemental planting transects will follow the same success criteria except the height requirement, and stems per acre will be total stems and not just planted stems. Green Mesa Mitigation Plan August 2018 40 8 MONITORING PLAN Annual monitoring data will be reported using the NCIRT monitoring template. The monitoring report shall provide a project data chronology that will facilitate an understanding of project status and trends, research purposes, and assist in decision making regarding project close-out. Monitoring reports will be prepared annually and submitted to the USACE. Monitoring of the Project will adhere to metrics and performance standards established by the USACE's April 2003 Wilmington District Stream Mitigation Guidelines and the NC IRT's October 2016 Wilmington District Stream and Wetland Compensatory Mitigation Update. Table 16 outlines the links between project goals, objectives, and treatments and their associated monitoring metrics and performance standards within the context of functional uplift based on the Stream Functions Pyramid Framework. 8.1 As -Built Survey An as -built survey will be conducted following construction to document channel size, condition, and location. The survey will include a complete profile of thalweg, water surface, bankfull, and top of bank to compare with future geomorphic data. Longitudinal profiles will not be required in annual monitoring reports unless requested by USACE. Stream channel stationing will be marked with stakes placed near the top of bank every 200 feet. 8.2 Visual Monitoring Visual monitoring of all mitigation areas will be conducted a minimum of twice per monitoring year by qualified individuals. The visual assessments will include vegetation density, vigor, invasive species, and easement encroachments. Visual assessments of stream stability will include a complete streamwalk and structure inspection. Digital images will be taken at fixed representative locations to record each monitoring event, as well as any noted problem areas or areas of concern. Results of visual monitoring will be presented in a plan view exhibit with a brief description of problem areas and digital images. Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal photos should indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral photos should not indicate excessive erosion or continuing degradation of the banks over time. A series of photos over time should indicate successional maturation of riparian vegetation. 8.3 Hydrology Events Crest gauges will be installed to document the occurrence of bankfull events. A minimum of one gauge will be installed on each tributary that is greater than 1,000 feet in length, with one gauge required for every 5,000 feet of length on each tributary and a maximum of five gauges per tributary. Reaches with Priority 1 Restoration (designed to reconnect the stream to its floodplain), gauges will be capable of tracking the frequency and duration of overbank events. Where restoration or enhancement activities are proposed for intermittent streams, monitoring gauges should be installed to track the frequency and duration of stream flow events. 8.4 Cross Sections Permanent cross sections will be installed at a minimum of one per 20 bankfull widths with half in pools and half in riffle on all Restoration and Enhancement I reaches. All cross section measurements will include bank height ratio and entrenchment ratio. Cross sections will be monitored in Years 1, 2, 3, 5, and 7. There should be little change in as -built cross sections. If changes do take place, they should be evaluated to determine if they represent movement toward a less stable condition (for example down - Green Mesa Mitigation Plan August 2018 41 cutting or erosion) or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). 8.5 Vegetation Monitoring Vegetation monitoring plots will be a minimum of 0.02 acres in size and cover a minimum of two percent of the planted area. There will be 12 plots within the planted area (13.7 acres). Plots will be a mixture of fixed and random plots, with eight fixed plots and four random plots. Planted area indicates all area in the easement that will be planted with trees. Existing wooded areas, including supplemental planting areas are not included in the planted area. The following data will be recorded for all trees in the fixed plots: species, height, planting date (or volunteer), and grid location. For random plots, species and height will be recorded for all planted woody stems. The location (GPS coordinates and orientation) of the random plots will be identified in the annual monitoring reports. Random transects (50 meters by 2 meters) will occur in the supplemental planting areas (roughly seven acres). There will be two transects on Reach FF1-B and two transects on Reach FF5 for a total of four transects. To measure these transects, a 50 -meter tape is stretched diagonally across the buffer corridor and any native volunteer or planted tree/shrub that falls within one meter of either side of the tape is recorded. The transects will be mapped and new locations will be monitored in subsequent years. Vegetation will be planted and plots established at least 180 days prior to the initiation of the first year of monitoring. Monitoring will occur in Years 1, 2, 3, 5, and 7 between July 1 st and leaf drop. Invasive and noxious species will be monitored and so that none become dominant or alter the desired community structure of the Project. If necessary, RES will develop a species-specific treatment plan. 8,6 Scheduling/Reporting A baseline monitoring report and as -built drawings documenting stream restoration activities will be developed within 60 days of the planting completion on the Project. The report will include all information required by IRT mitigation plan guidelines, including elevations, photographs and sampling plot locations, gauge locations, and a description of initial species composition by community type. The report will also include a list of the species planted and the associated densities. Baseline vegetation monitoring will include species, height, date of planting, and grid location of each stem. The baseline report will follow USACE guidelines. The monitoring program will be implemented to document system development and progress toward achieving the success criteria. The restored stream morphology will be assessed to determine the success of the mitigation. The monitoring program will be undertaken for seven years or until the final success criteria are achieved, whichever is longer. Monitoring reports will be prepared in the fall of each year of monitoring and submitted to the IRT. The monitoring reports will include all information and be in the format required by USACE.

Project maintenance will be performed as described previously in this document. If, during the course of annual monitoring, it is determined that the Project's ability to achieve performance standards are jeopardized, RES will notify the USACE of the need to develop a Plan of Corrective Action. Once the Corrective Action Plan is prepared and finalized RES will: 1. Notify the USACE as required by the Nationwide 27 permit general conditions. 2. Revise performance standards, maintenance requirements, and monitoring requirements as necessary and/or required by the USACE. 3. Obtain other permits as necessary. 4. Prepare Corrective Action Plan for review and approval by IRT. 5. Implement the Corrective Action Plan. Provide the IRT a Record Drawing of Corrective Actions. This document shall depict the extent and nature of the work performed. Green Mesa Mitigation Plan August 2018 44 10 LONG-TERM MANAGEMENT PLAN Upon approval of the Project by the IRT, the Project will be transferred to Unique Places to Save (UP2S): Unique Places to Save (585) 472-9498 PO Box 1183 Chapel Hill, NC 27514 info@uniqueplacestosave.org UP2S will be responsible for periodic inspection of the site to ensure that restrictions required in the Conservation Easement or the deed restriction document(s) are upheld. Easements will be stewarded in general accordance with the guidelines published by the National Land Trust Alliance. Specific responsibilities include: • Monitoring of site is conducted on an annual basis. • An on-site inspection is conducted once per year. Visits to the site are coordinated with landowner when possible. Annual monitoring reports are sent to the landowner when possible. Signage for the easement boundary is maintained. Violations and potential violations of the conservation easement deed are promptly communicated to the landowner. A model conservation easement and engagement letter from UP2S are included in Appendix C. The engagement letter includes itemized annual cost accounting of long-term management, total amount of funding, and the manner in which the funding will be provided. Green Mesa Mitigation Plan August 2018 45 11 CREDIT RELEASE SCHEDULE All credit releases will be based on the total credit generated as reported in the approved mitigation plan of the site. Under no circumstances shall any mitigation project be debited until the necessary DA authorization has been received for its construction or the District Engineer (DE) has otherwise provided written approval for the project in the case where no DA authorization is required for construction of the mitigation project. The DE, in consultation with the IRT, will determine if performance standards have been satisfied sufficiently to meet the requirements of the release schedules below. In cases where some performance standards have not been met, credits may still be released depending on the specifics of the case. Monitoring may be required to restart or be extended, depending on the extent to which the site fails to meet the specified performance standard. The release of Project credits will be subject to the criteria described in Table 17. 11.1 Initial Allocation of Released Credits The initial allocation of released credits, as specified in the mitigation plan can be released by the IRT with written approval of the DE upon satisfactory completion of the following activities: a) Execution of the UMBI by the Sponsor and the USACE; b) Approval of the final mitigation plan; c) Mitigation site must be secured; d) Delivery of financial assurances; e) Recordation of the long-term protection mechanism and title opinion acceptable to the USACE; f) Issuance of the 404 -permit verification for construction of the site, if required. 11.2 Subsequent Credit Releases The second credit release will occur after the completion of implementation of the Mitigation Plan and IRT approval of the Baseline Monitoring Report and As -built Survey. All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a determination that required performance standards have been achieved. As projects approach milestones associated with credit release, the Sponsor will submit a request for credit release to the DE along with documentation substantiating achievement of criteria required for release to occur. This documentation will be included with the annual monitoring report. Green Mesa Mitigation Plan August 2018 46 Table 17.

Green Mesa Mitigation Plan August 2018 47 12 MAINTENANCE PLAN The Project will be monitored on a regular basis and a physical inspection will be conducted a minimum of once per year throughout the post construction monitoring period until performance standards are met. These site inspections may identify site components and features that require routine maintenance. Routine maintenance should be expected most often in the first two years following site construction and may include the following: Table 18. Maintenance Plan Component/Feature Maintenance through project close-out Stream Routine channel maintenance and repair activities may include chinking of in -stream structures to prevent piping, securing of loose coir matting, and supplemental installations of live stakes and other target vegetation along the channel. Areas where stormwater and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head -cutting. Stream maintenance activities will be documented and reported in annual monitoring reports. Stream maintenance will continue through the monitoring eriod. Vegetation Vegetation shall be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be treated by mechanical and/or chemical methods. Any vegetation control requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. Vegetation maintenance activities will be documented and reported in annual monitoring reports. Vegetation maintenance will continue through the monitoring period. Site Boundary Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries will be marked with signs identifying the property as a mitigation site and will include the name of the long-term steward and a contact number. Boundaries may be identified by fence, marker, bollard, post, tree -blazing, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as -needed basis. Easement monitoring and staking/signage maintenance will continue in perpetuity as a stewardship activity. Road Crossing Road crossings within the site may be maintained only as allowed by Conservation Easement or existing easement, deed restrictions, rights of way, or corridor agreements. Crossings in easement breaks are the responsibility of the landowner to maintain. Livestock Fencing Livestock fencing is to be placed outside the easement limits. Maintenance of fencing is the responsibility of the landowner. Beaver Routine site visits and monitoring will be used to determine if beaver management is needed. If beaver activity poses a threat to project stability or vegetative success, RES will trap beavers and remove impoundments as needed. All beaver management activities will be documented and included in annual monitoring reports. Beaver monitoring and management will continue through the monitoring period. Green Mesa Mitigation Plan August 2018 48 13 FINANCIAL ASSURANCES CONFIDENTIAL The Sponsor will provide financial assurances in the form of a $681,000 Construction Performance Bond to the USACE to assure completion of mitigation construction and planting. Construction and planting costs are estimated to be at or below $681,000 based on the Engineer's construction materials estimate and recent bid tabulation unit costs for construction materials. Following completion of construction and planting the Construction Performance Bond will be retired and a $105,000 Monitoring Performance Bond will be provided to assure completion of seven years of monitoring and reporting, and any remedial work required during the monitoring period. The $105,000 amount includes contingency and estimated monitoring costs from the Engineer. The Monitoring Performance Bond will be reduced by $15,000 following approval of each annual monitoring report. The Monitoring Performance Bond will be retired in total following official notice of site close-out from the IRT. Financial assurances shall be payable to a standby trust or other designee at the direction of the obligee. Financial assurances structured to provide funds to the USACE in the event of default by the Bank Sponsor are not acceptable. A financial assurance must be in the form that ensures that the USACE receives notification at least 120 days in advance of any termination or revocation. The Performance Bonds will be provided by a surety listed with the U.S. Treasury and has an A.M. Best Rating of B or above. All Performance Bonds will be submitted to the USACE in draft form for approval prior to execution. In the event of Sponsor default, UP2S has agreed to receive the funds and ensure the work is successfully completed. Table 19.

Each plot is a 5m X 20m belt transect, positioned parallel to the channel in the floodplain or adjacent upland. Take a GPS point at the origin and set the bounds with 5m as the "x-axis" and 20m as the "y-axis." Set the plot with the y-axis as the side parallel to the stream channel. Record the y-axis azimuth to allow for future resampling. Conclude selection and set-up with a representative photo of the plot taken from the origin. Data Collection Identify each plant in the plot to the species level. Sort and measure tree species by height class and diameter at breast height (DBH). Count seedlings <54in (137cm) in height into height categories 0-9cm, 10-50cm, 51-100cm, or 101-137cm. Count saplings >54in (137cm) in height into DBH categories 0-lcm, 1-2.5cm, 2.5-5cm, or 5-12.7cm. Measure the DBH of all trees >5in (12.7cm) DBH. Shrubs, vines, and herbaceous taxa receive an estimation of their percent cover over the substrate within the plot. If the personnel are unable to identify to the species level, collect voucher photos and/or specimen(s) for later identification. Record these on the data sheet as UNK-1, UNK-2, etc. Data Processing Begin processing collected data by identifying the unknown species observed from voucher photos and specimen(s) collected. When species present are sufficiently identified, use the dominant canopy species assemblages and ecological region to identify a habitat type from Schafale (2012). Calculate both basal area and stems per acre for each plot surveyed using the formulas below. These metrics help to inform the existing conditions of the canopy on-site and inform the development of the project's planting plan. Basal Area Formula: Basal area of each tree (m2) = 0.00007854 X (DBHcm)2 Basal area of plot (m2/ha) = (sum of basal areas for all trees in plot) X 100 •100 is to scale up from our 0.01ha plot to lha Stems per Acre Formula: Stems/Acre = (# of stems)/0.02471 VP -3 .4 t*v\ 10 11w L w o ` +) EUJ O f N N L In In N Cu iT A II .r cor- n A LU r� ELU c H 0 N .I N Ln U LQ N N V C O = m Ln ei � N � i Q o v z v3 m.

An important aspect of achieving this is to conduct our stewardship monitoring practices in a professional, accurate, and efficient manner. The following procedures and guidelines will help ensure that staff will have the guidance and expertise to properly monitor UP2Save's conservation easements. UP2Save's stewardship monitoring procedures and guidelines are separated into three stages: (1) pre -monitoring due diligence; (2) monitoring of the easement property; and (3) post -monitoring due diligence. Each stage in the monitoring process is crucial in employing sound monitoring practices and creating accurate and reliable documentation. Pre -monitoring Due Diligence: Pre -monitoring due diligence includes components that prepare the monitor for the impending field work and documentation of their stewardship activities. The following procedures shall be followed prior to all conservation easement monitoring visits: 1. Contact the landowner to schedule a monitoring visit at least one to two weeks prior to the scheduled visit either by phone, email, or letter (make an effort to group monitoring visits to multiple easements in the same general area in one trip). 2. Make an effort to invite the landowner to be involved in the monitoring process. Usually having the landowner available for questions or discussion of issues before and after monitoring is fine. It is not necessary that the landowner accompany the monitor around the property unless the landowner prefers to do So. 3. If unknown, acquire any information needed to access the property (e.g. lock combinations, gate locations, road/trail locations, contact information for land managers and neighboring landowners). 4. A few days prior to the monitoring visit, make an effort to contact the landowner to confirm the monitoring date. 5. Prior to the monitoring date, review the conservation easement deed, baseline documentation report, most recent monitoring report, and any other pertinent information (e.g. landowner correspondence, older monitoring reports). 6. Create a monitoring map of the property using aerial imagery or a topo map as the base layer. Ensure that the property boundary is clearly depicted on the map as well as any building envelopes or other important boundaries or landscape features (e.g. stream buffers, forest management plots, property points of access). 7. Enter the property boundary and BDR photopoint locations (if available) into a GPS unit for field reference. 8. Inform at least two staff members of your schedule and destination(s). Have an emergency contact phone number available at the office. 9. Monitoring material that is needed on the monitoring visit includes: a. Stewardship Binder b. Monitoring map c. GPS unit (with extra batteries) d. Compass e. Camera (with extra batteries) f. Notepad 10. Prepare for your field work. Bring necessary field equipment to conduct a safe and effective monitoring visit. Field equipment should include: Required a. Sunscreen b. Extra water c. Extra clothing d. Extra food e. Extra cash f. Topo map of greater area g. First Aid/Survival Kit h. Blanket(s) i. Shovel j. Spare tire(s) k. Cell phone 1. Flares in. Bolt cutters n. Crowbar Optional a. Tent b. Sleeping bag c. Firearm(s) d. Stove e. Laptop computer f. Bear spray Approximate pre -monitoring due diligence completion time: 3 hours Monitoring of the Easement Property The field portion of the monitoring effort should be interpreted as (1) an opportunity to maintain and improve relations with landowners and/or landowner representatives; (2) a small-scale duplication effort of the baseline documentation report; (3) an opportunity to enhance, alter, or correct any deficiencies or errors in past monitoring efforts; and (4) a check on the activities within and conditions of the property under easement. The following procedures and guidelines will help ensure the efficiency, accuracy, and safety of a monitoring visit: 1. The monitor should have a clear strategy of how the property will be monitored prior to the site visit. 2. Meet with the landowner if possible prior to engaging in field work. Ask about land management activities (past, present or future), activities on adjacent lands, and any other issues related to the terms of the conservation easement. 3. Invite the landowner to accompany the monitor in the field. This is not necessary, but it is polite to ask. 4. Enact the monitoring strategy laid out prior to the visit using all tools available (e.g. GPS, compass, maps, photos). 5. Use GPS to track the monitoring route and take coordinates of photopoint locations. Use the compass to take azimuth readings at the photopoint locations (direction photo was taken). All photopoint coordinates must be taken in UTM coordinates, Zone 13. All azimuth reading must be taken using the 3 -digit method (0 to 360°) to decrease ambiguity as opposed to using quadrants. For example, recording a bearing of 192° is much clearer than 12° W of S, or S12°W. 6. Walk or drive as much of the property as possible making an effort to visit all access points, boundary lines, and property corners. Pay special attention to building envelope areas and other areas that may have more restrictive covenants (e.g. stream corridors, no - timbering zones, high quality habitat areas). 7. Duplicate the photopoint locations that are depicted in the BDR. If new photopoint locations are required; develop the new photopoint locations based upon current landscape conditions and activities. Document these new locations in the monitoring report and make notes that future monitoring efforts should follow the new photopoint format. Note: the original photopoints portrayed in the BDR must always be replicated unless the BDR is amended to not include certain photopoint locations. 8. TAKE FIELD NOTES! Do not rely on memory to complete the monitoring report. 9. Make an effort to meet with the landowner after the field visit to discuss any minor, non - violation issues or other observations made while conducting the field visit. Do not, under any circumstances, discuss potential minor or major violations to the conservation easement with the landowner. UP2Save has specific procedures to follow when addressing potential violations (see UP2Save's Conservation Easement Violations Policy). Approximate monitoring completion time: 4-16 hours depending upon driving time and size/complexity of property. Post -monitoring Due Diligence: - Post -monitoring due diligence primarily consists of developing documentation of the monitoring visit. This documentation consists of - 1 . £ 1. Filling out the monitoring report 2. Creating a monitoring map including the photopoints, access points, monitoring track, and any other points of interest. 3. Writing a letter to the landowner that summarizes the monitoring visit and also states that the landowner is in compliance with the terms of the conservation easement. If the landowner is not in compliance with the terms of the conservation easement, then staff will follow the UP2Save's Conservation Easement Violations Policy. 4. Properly duplicate the monitoring report and file all copies according to the UP2Save's Stewardship Records Management Policy. Mail the signed monitoring report and compliance letter to the landowner and any representatives listed in the baseline or that have received monitoring reports in the past. Schedule the next monitoring visit based upon observations in the field and seasonal access to the property.

As part of this scope of work, RES is submitting this request to the U.S. Army Corps of Engineers (Corps) for a confirmation of the limits of Waters of the U.S. on the subject site. The Green Mesa Site is a part of the Yadkin 01 Stream and Wetland Umbrella Mitigation Bank. The proposed umbrella structure of the Bank is designed to initially permit five mitigation sites, and establish the umbrella banking instrument for future mitigation sites. The first five sites are Gideon, Compass Point, Green Mesa, Twiman, and Scout. These sites are identified as having potential to help meet the compensatory mitigation requirement for stream impacts in hydrologic unit 03040101 of the Yadkin River Basin. The purpose of the proposed Site is to generate compensatory mitigation credits for inclusion in the RES Yadkin 01 Stream and Wetland Umbrella Mitigation Bank in hydrologic unit 03040101 of the Yadkin River Basin associated with Department of the Army permit authorizations pursuant to Section 404 of the Clean Water Act. The stream channels on the site have been classified using the North Carolina Division of Water Resources methodology. Current stream conditions along the proposed reaches demonstrate habitat degradation as a result of impacts from livestock and a lack of riparian buffers. The restoration approach for this project will be a combination of restoration, enhancement, and preservation. Proposed treatment activities may range from minor bank grading and planting to re-establishing stable planform and hydraulic geometry. The objective of this approach is to design a geomorphically stable channel that provides habitat improvements and ties into the existing landscape. Within the boundaries of the proposed project, two jurisdictional wetlands are present. The Restoration Plan for both sites is currently in development.

Further, an AJD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA.

(Property Owner Authorized Signature) (Property Owner Printed Name) 710 Date Date Jurisdictional Determination Request F. JURISDICTIONAL DETERMINATION (JD) TYPE (Select One) ❑� I am requesting that the Corps provide a preliminarX JD for the property identified herein. A Preliminary Jurisdictional Determination (PJD) provides an indication that there may be "waters of the United States" or "navigable waters of the United States"on a property. PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all waters and wetlands on the property will be treated as if they are jurisdictional "waters of the United States". PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is "preliminary" in the sense that an approved JD can be requested at any time. PJDs do not expire. ❑ I am requesting that the Corps provide an approved JD for the property identified herein. An Approved Jurisdictional Determination (AJD) is a determination that jurisdictional "waters of the United States" or "navigable waters of the United States" are either present or absent on a site. An approved JD identifies the limits of waters on a site determined to be jurisdictional under the Clean Water Act and/or Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be posted on the Corps website. A landowner, permit applicant, or other "affected party" (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years (subject to certain limited exceptions explained in Regulatory Guidance Letter 05- 02). I am unclear as to which JD I would like to request and require additional information to inform my decision. G. ALL REQUESTS Map of Property or Project Area.

These site inspections may identify the presence of invasive vegetation. RES will treat invasive species vegetation within the project area and provide remedial action on a case by- case basis. Common invasive species vegetation, such as Chinese privet (Ligustrum sinense), multiflora rose (Rosa multiflora), tree -of -heaven (Ailanthus altissima), and Japanese honeysuckle (Lonicera japonica), will be treated to allow native plants to become established within the conservation easement. Invasive species vegetation will be treated by approved mechanical and/or chemical methods such that the percent composition of exotic/invasive species is less than 5% of the total riparian buffer area. Any control methods requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. If areas of invasive species exist within the easement, they will be monitored yearly as part of the monitoring protocol, and treated if necessary. If required, problem areas will continue to be treated until the project easement shows overall trending towards meeting all monitoring requirements.

The purpose of this notice was to solicit the views of interested State and Federal agencies and other parties either interested in or affected by the proposed work. In addition, the Corps and members of the Interagency Review Team (IRT) conducted field reviews of the proposed mitigation sites on October 16 - 18, 2017. Attached are comments received in response to the public notice from the North Carolina Wildlife Resource Commission, and a field visit memo incorporating comments from the attending IRT members. The Corps has reviewed the information provided and considered the comments received in response to the public notice and the field site visits. We have determined that the proposed mitigation bank appears to have the potential to restore and protect aquatic resources within the Upper Yadkin 8 -digit Hydrologic Unit Code (HUC) 03040101 of the Yadkin River Basin. Therefore, the bank sponsor may proceed with preparation of a draft Mitigation Banking Instrument (MBI). We appreciate your interest in restoring and protecting waters of the United States. If you have questions concerning the path forward for the proposed mitigation bank, please do not hesitate to contact me at (919) 554-4884 extension 59.

NCWRC staff attended site visits with regulatory agency staff October 16-18. The prospectus proposes stream restoration, enhancement, and preservation on over 29,800 feet of stream to net over 18,000 SMUs in the Yadkin River Basin (03040101). The bank includes five sites, and general comments on each site follow: • Gideon Site. Located on a 76 -acre parcel and sandwiched between two Division of Mitigation Services (DMS) sites, this agricultural site will involve restoration, enhancement, and preservation on 4,092 ft of Mill Creek and unnamed tributaries (UTs) to Mill Creek, netting 2,664 SMUs. The site is less than a mile upstream of the Mitchell River, which serves as habitat for Brook Floater (Alasmidonta varicosa, US Federal Species of Concern, NC Endangered). Excellent erosion and sediment control is especially important at both this site and the adjacent DMS sites to minimize impacts to this mussel. • Compass Point Site. This site is located on a 209 -acre parcel in agricultural and forestry uses. It was recently logged. The project will involve restoration and enhancement on 5,024 ft of UTs to the Yadkin River, netting 3,709 SMUs. The downstream end of the site is at the confluence with the Yadkin River, and protection and enhancement of riparian habitat at this location is especially ecologically beneficial, as it will provide a wildlife corridor that is connected to the Yadkin River. We recommend that the landowner expand the forested riparian area along the Yadkin River, as well. Two rare mussels [Creeper (Strophitus undulatus, NC Threatened) and Brook Floater] are found in the Yadkin River in the vicinity Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 RES Yadkin 01 Mitigation Bank Page 2 October 26, 2017 Davie, Yadkin, Surry Counties of the project, and erosion and sediment control is especially important at this site to minimize impacts to these species. Green Mesa. This site is on a 273 -acre parcel in agricultural use, and project activities include restoration, enhancement, and preservation on 7,776 ft of UTs to North Deep Creek, netting 3,531 SMUs. The old dam structure downstream of the present dam may serve as bat habitat, and NCWRC biologists may perform bat surveys there in 2018. Twiman. This site is comprised of 10 parcels totaling 266 acres in agricultural use, and project activities include restoration, enhancement, and preservation on 10,477 ft of UTs to North Deep Creek, netting 5,766 SMUs. Scout. This site is on two parcels totaling 522 acres in agricultural use, and project activities include restoration on 2,467 ft of Hauser Creek, netting 2,467 SMUs. Detailed comments on the mitigation approach are captured in RES staff's October 16-18 site visit summary. NCWRC staff has reviewed this summary and has provided comments on it in a separate email.

While each project could be developed independently of the other, the combined easements will result in a much larger contiguous protected corridor and high- quality aquatic habitat. WRC mentioned that there are known occurrences of the brook floater (Alasmidonta varicosa) in the Mitchell River, approximately 0.5 miles downstream of the project area which RES mentioned in the Prospectus. Connecting the Gideon and Little Sebastian Sites offer opportunities to create and protect habitat for the State protected species. IRT members agreed the Gideon site is acceptable for compensatory mitigation, and final credit ratios will be determined in the Approved Mitigation Plan. Reach specific comments are below. • DWR requested that RES determine the potential wetlands on site. RES is currently delineating the site. • MC3-A: Group agreed to restoration at 1:1 ratio as originally proposed in prospectus. RES explained that cows have full access and the landowner has historically moved the channel. RES affirmed that construction sequencing would harvest native bed material when possible (e.g. cobble). The crossing will be a culvert. • JN5 — Group thought that Enhancement I at a 1.5:1 ratio would be more appropriate approach for this reach instead of Enhancement II. Enhancement measures will include grading banks, installing grade control structures (including at the tie-in with MC3-A), planting the buffer, and cattle exclusion. • JN4 — Similar to JN5, the Group thought that Enhancement I at a 1.5:1 ratio would be a more appropriate approach for below the crossing. Enhancement measures will include removing pipe in old channel, fixing current culvert, grading banks, installing grade control structures, planting the buffer, and cattle exclusion. Enhancement III at a 5:1 ratio is the approach for above the crossing and includes cattle exclusion and light supplemental planting. • MC3-B: RES originally proposed Enhancement II at 2.5:1, but the Group agreed to change the approach to Enhancement III at 5:1 ratio because of channel condition and cattle access. Enhancement measures will include planting the buffer on the left bank and cattle exclusion. • JN6-C — RES originally proposed restoration on this reach and Group agreed to that approach. However, proposed alignment and restoration approach will need to be dictated by topographic survey data. RES is in process of data collection, including delineating slough feature. WRC suggested fencing slough area if not in alignment of proposed restoration area. Barns will likely be removed and the culvert at the driveway will be reset to improve hydrologic connection to JN6-B. WRC Comment: At the break between JN6-B & JN6-A, there is an old road that is eroding. RES agreed to stabilize this road. • JN6-B — RES originally proposed Enhancement II on this reach. DWR did not agree to 2.5:1 ratio due to buffer being intact, but does agree this reach should be part of the overall project. The consensus was Enhancement III at a 5:1 ratio with an approach of removing the crossing and cattle exclusion. • JN6-A — RES originally proposed preservation on this reach. Group agreed to including this top part of the reach as preservation. The JD will determine the limits. Compass Point Site —10/16/17 IRT members agreed the Compass Point site is acceptable for compensatory mitigation, and final credit ratios will be determined in the Approved Mitigation Plan. Reach specific comments are below. • DW6: RES originally proposed Enhancement II at 2.5:1 ratio. WRC and DWR recommended more of an Enhancement I approach (ranging from a 1.5 to 2 ratio), which would include bank work (spot stabilization), riparian buffer planting, and livestock exclusion. • DW1-A: RES originally proposed restoration at 1:1 ratio and Group agreed, with the exception being the upstream most portion that ties into DW6. Group agreed that a mix of Enhancement I and II would be best approach on the first 250 feet of DWI -A. • DW2: Group agreed to Enhancement II at 2.5:1 ratio as originally proposed in prospectus. RES confirmed that cows have access. Enhancement measures will include planting the riparian buffer and cattle exclusion. DWR and RES agreed to installing a stream gauge midway on the reach to monitor hydrology. • DW1-B: RES originally proposed Enhancement II at 2.5:1 ratio. Group discussed Enhancement I at a 1.5:1 ratio with enhancement measures including a combination of bed and bank work, complete riparian buffer planting, and cattle exclusion. DWR Comment: there was some discussion of E1, however, if that ratio is proposed vs the E2, then the work needs to be justified in the mit plan. For the reach DWI -D, DWR believes while it is a benefit to have a corridor connect to the Yadkin River, however, the ratio that is appropriate would be no better than 7.5:1. USACE Comment: This will transition from restoration in DWI -A at bedrock point. Buffered on one side, some areas do need bank shaping. EII only if the banks are addressed. The existing road may cause the buffer to be pinched to less than 50' at the end of the reach. • DW1-C: RES originally proposed restoration at 1:1 ratio. This reach has patches of high quality bed material including cobble and bedrock. Group agreed a Priority II Restoration approach, including benching to aid in floodplain connectivity, would be the best measure. • DW1-D — RES originally proposed Enhancement III at a 5:1 ratio on this reach. WRC wants to see this reach protected and included in the project. DWR and USACE recommended a 7.5:1 ratio. The approach will be cattle exclusion and installing a boulder grade control structure below the limits of restoration on DWI -C. WRC Comment: We support the protection and riparian buffer enhancement of this reach, which would protect a riparian corridor that would connect the Yadkin River to the site. Green Mesa Site —10/17/17 Overall the site has clear potential for functional uplift, but there are a few notable constraints including powerline easement and a large pond that will remain (landowner will not allow pond to be part of project). Because the pond will remain in place, RES and USACE discussed potentially retrofitting the riser structure to include a bottom pond drain to release cooler water. IRT members agreed the Green Mesa site is acceptable for compensatory mitigation, and final credit ratios will be determined in the Approved Mitigation Plan. Reach specific comments are below. • FF4 and FFI-D: RES originally proposed restoration at a 1:1 ratio. The approach is a mix of Priority I and II restoration with potential for enhancement level I above the powerline based on bedrock in the channel. USACE said clearly justify rationale for restoration measures. • FF 1-C: RES originally proposed enhancement II at a 2.5:1 ratio. DWR and USACE stated if channel was left in place and enhancement II approach was taken that it was likely for no credit to be given due to powerline and lack of buffer near the road. Group discussed starting restoration immediately below Baptist Church Road and RES agreed this was best option if feasible. WRC Comment: There was discussion of raising the bed elevation to lessen the DOT culvert perch. The discussion on lower FFI-C being too close to the road also applies to upper FFI-D. Turning the channel into the field upstream of where it turns now could allow R credit for both. • FF1-C (below pond): RES originally proposed enhancement II at a 2.5:1 ratio with an approach of cattle exclusion, buffer planting, and tying into the restoration area. There is a large stone wall in this reach with a culvert that might need to be retrofitted (if possible). Group agreed the best approach is probably to leave the wall in place and credit the enhancement at 3:1. USACE Comment: I agree with your summary for both areas above and below the pond. It's recommended that SHPO review this area (and the area where the other historic wall is in the buffer in FF1-A). • FF5: RES originally proposed enhancement III at a 5:1 ratio with an approach of cattle exclusion, invasive species treatment, and supplemental planting on right bank. DWR stated there is no cattle pressure and there is decent buffer on the banks, but invasives are problematic (high density of privet). WRC would like some of the black walnut removed and those areas replanted with a more diverse mix of native hardwood vegetation. USACE and DWR suggested a ratio of 7.5:1; however, if buffer planting and easement was extended to at least 100 feet a higher ratio could be approved. • FF3-A: RES originally proposed enhancement II at a 2.5:1 ratio with an approach of cattle exclusion and buffer planting. During the site visit RES suggested enhancement I at a 1.5:1 ratio with an added measure of bank stabilization to reduce shear stress and in - channel erosion. WRC agreed to rationale for enhancement I approach, but DWR stated that there isn't much work needed on this reach and a ratio of 5:1 is likely most appropriate (see FF3-B below). DWR Comment: I had FF3A and B combined at a ratio of 7.5:1. WRC Comment: We did not agree with the E1 approach, as this reach has a stellar riparian forest; definitely agree on an E3 approach here, as light tough is needed and riparian area is too nice to justify getting heavy equipment to address channel erosion. USACE Comment: Widening the buffer and invasives control are necessary here. My notes indicate a ratio of 5-7:5:1, depending on justification of functional uplift. The historic house in the buffer should be addressed. • FF3-B: RES originally proposed enhancement III at a 5:1 ratio with an approach of cattle exclusion and light supplemental planting. IRT suggested combining FF3-A and FF3-B into one reach and having the entire crediting approach be enhancement III at a 5:1 ratio. This area might be generating wetlands that RES would not be claiming credit. RES is currently delineating the site. DWR Comment: I had FF3A and B combined at a ratio of 7.5:1. USACE Comment: Widening the buffer and invasives control are necessary here. My notes indicate a ratio of 5-7:5:1, depending on justification of functional uplift, especially considering these enter the pond. A narrative of historical farming practices would be beneficial. • FF1-B: RES originally proposed enhancement III at a 5:1 ratio and Group agreed and stated to justify the uplift in the mitigation plan. WRC Comment: There is evidence of beaver here. • FF2: RES originally proposed preservation and Group agreed to a 7.5:1 ratio with an approach of fencing where needed. DWR Comment: DWR could go with 7.5:1 on the preservation (FF2) but would like to see the reach extended above the crossing at the top and fenced out. WRC Comment: There was a discussion on preserving a little more above the fence line and whether the old road would be planted/fenced. There was a question on the location of the property line and end of preservation. USACE Comment: Channel in good condition, USACE feels preservation at 10:1 is appropriate. The discussion of 7.5:1 would be entertained if the upstream portion excluded cattle, as well. • FF 1-A: RES originally proposed enhancement II at a 2.5:1 ratio with an approach of cattle exclusion and buffer planting. While there might be some opportunities for bank work, the group agreed that the enhancement II approach was best based on the amount of bedrock in this reach. Twiman Site —10/17/17 IRT members agreed the Twiman site is acceptable for compensatory mitigation, and final credit ratios will be determined in the Approved Mitigation Plan. Reach specific comments are below. • TC2-A: RES originally proposed Enhancement I at 1.5:1 ratio with an approach of cattle exclusion, buffer planting, and bank stabilization. Group agreed to this approach. • TC2-B: RES originally proposed restoration at 1:1 ratio. Group generally agreed with this approach, but did note there is a section of potential enhancement I below the pond. Upon further data collection/analysis, RES will determine the best approach for this section of TC2-13. WRC Comment: The group discussed establishing the break between EI and R at the bedrock nickpoint. • TC1-A: RES originally proposed restoration at 1:1 ratio. Group agreed to this approach. • TC3-A: RES originally proposed Enhancement II at 2.5:1 ratio with an approach of cattle exclusion, buffer planting, invasive species treatment and spot stabilization. Group agreed to this approach with a ratio ranging from 2.5 to 3 to be justified in the mitigation plan. • TC1-B: RES originally proposed Enhancement III at 5:1 ratio with an approach of cattle exclusion and buffer planting. IRT suggested restoration as the approach. RES is open to examining restoration along this reach based on watershed size and design discharge. DWR Comment: these reaches should be restoration. If RES decides that restoration not feasible then the ratio for enhancement would be greater than 5:1, could be as high as 8:1. Planting outer 20 feet just does not do a lot for this system. USACE Comment: This channel is incised, poor substrate, no buffer, channelized, with an available floodplain. USACE & DWR feel restoration is appropriate. • TC4: RES originally proposed Enhancement III at 5:1 ratio with an approach of cattle exclusion and buffer planting. IRT suggested restoration as the approach. RES is open to examining restoration along this reach based on watershed size and design discharge. DWR Comment: these reaches should be restoration. If RES decides that restoration not feasible then the ratio for enhancement would be greater than 5:1, could be as high as 8:1. Planting outer 20 feet just does not do a lot for this system. USACE Comment: This channel is incised, poor substrate, no buffer, channelized, with an available floodplain. USACE & DWR feel restoration is appropriate. • TC5-B: RES originally proposed Enhancement II at 2.5:1 ratio with an approach of cattle exclusion, buffer planting, and minor spot stabilization. IRT suggested a lower ratio of 3:1 in some areas based on existing buffer condition. RES recommends potentially splitting the reach into different treatments based on level of intervention and will justify rationale in mitigation plan. • TC7: RES originally proposed Enhancement II at 2.5:1 ratio with an approach of cattle exclusion, buffer planting, invasive species treatment and spot stabilization. Group agreed to this approach with a ratio ranging from 2.5 to 3 to be justified in the mitigation plan. USACE Comment: 3:1 ratio would be more appropriate. • TC6: RES originally proposed Enhancement II at 2.5:1 ratio with an approach of cattle exclusion and buffer planting. This reach is in a deeply formed gully, but is currently stable with the exception of multiple headcuts at the top of the reach. DWR suggested "filling in" the reach to bring the bed up and credit as restoration with a 1:1 ratio. RES expressed concerns with filling in the gully because thee stream might lose jurisdictional status after construction with such a small watershed (roughly 20 acres). DWR Comment: Reach TC6 may not be a creditable reach. While I feel that the only beneficial treatment would be filling like a RSC approach it is likely the stream would lose flow. Planting the outer 20 feet for this reach would not be creditable enhancement either. USACE Comment: I would question whether there would be flow if the bed was raised with restoration. USACE would not release credit if the restored channel was not jurisdictional. The channel is part of the larger system, and the lower portions of this reach would benefit from cattle exclusion. I would suggest a lower EII ratio of 5-7.5:1. • TC5-A: RES originally proposed Enhancement III at 5:1 ratio with an approach of cattle exclusion and buffer planting. IRT agreed that this is an appropriate approach, but RES needs to clearly justify the rationale for the enhancement on this reach. DWR Comment: IRT suggested 7.5:1, would consider 5:1 if justified in mit plan. WRC Comment: RES will need to address the issue of cattle accessing land via passage under the bridge and the associated erosion. USACE Comment: USACE and DWR agreed that 7.5:1 would be more appropriate, unless 5:1 can be justified. Scout Site- 10/18/17 The Scout Site is located just upstream of the lower portion of the recently contracted DMS Mockingbird Site. While each project could be developed independently of the other, the combined easements will result in a better project and most importantly provide the opportunity to add over 2,000 linear feet of priority I restoration and limit the amount of priority II restoration on the Mockingbird Site. IRT members agreed the Scout site is acceptable for compensatory mitigation, and final credit ratios will be determined in the Approved Mitigation Plan. Reach specific comments are below. • HC3: Group agreed that restoration at 1:1 ratio is the best approach for this reach and including it will improve the development of the Mockingbird project. USACE commented that a hunting blind within the proposed easement area will need to be removed. There is an existing crossing that will be removed as part of the design. RES also showed a tributary that was not included in the prospectus that would be eligible for potential restoration credit at the tie-in with HC3, but would more likely be Enhancement II for the rest of the reach. a North Carolina Department of Natural and Cultural Resources State Historic Preservation Office Ramona h1.

Andrea, Thank you for the opportunity to provide feedback and comments on the Public Notice (SAW - 2017 -01462) for the RES Yadkin 01 Umbrella Mitigation Bank (Bank) Prospectus. The bank Sponsor, Environmental Banc and Exchange, LLC wishes to establish a commercial umbrella mitigation bank to generate mitigation banking credits to provide compensatory mitigation for unavoidable impacts to aquatic resources associated with Section 404 permits within the Upper Yadkin River Basin HUC 03040101. The Bank consists of establishing five mitigation sites expected to provide approximately 6,373 cool Stream Mitigation Units (SMU) and 11,764 warm SMUs by restoring, enhancing and preserving over 29,800 linear feet of stream and riparian corridor. The project is designed to address stressors identified in the watershed and provide improvements and ecological uplift to water quality, hydrologic function and both aquatic and terrestrial habitat. The EPA Region 4 Ocean, Wetlands and Stream Protection Branch offers the following comments as they pertain to RES Yadkin 01 Umbrella Mitigation Bank Final Prospectus dated July, 2017 and the Public Notice dated September 6, 2017. Section 1.4/Page 3: The project goals stated are too broad and somewhat vague. For example, the goal: "Nutrient removal" and a few others may be better presented as "Intercept, filter, minimize and potentially eliminate nutrients (such as...), sediment and other pollutants/pathogens before entering the aquatic environment". o The goal of "Improved aquatic and terrestrial habitat" is also vague and does not address any particular habitat or species of interest. Since we have cool water habitats being presented for restoration/enhancement then the goals should address the habitat types and rationale for considering them. o "Invasive species treatment" is more of an objective or action (and is stated as such in the document) to address the real goal of "Eliminate competition to native vegetation from exotic and invasive floral species". o I understand that many of the "goals" presented are at the prospectus level and not necessarily applicable to each site but without clear goals, the establishment of objectives and performance standards that relate back to the goals and functional uplift of the site becomes more challenging. • Section 3.7/Page 6: The last sentence should read: "If planted tree mortality affects 40 percent or greater of the initial planting in a stream or wetland restoration or enhancement area, then a remedial/supplemental planting plan will be implemented for the affected area(s)." This addresses "planted" vs. "volunteer" mortality and defines the starting point to consider mortality. • Section 5.1/Page 9: Be sure to continue coordinating the work at the Gideon Site with the Little Sebastian sites and ensure the Mitigation Plan is updated with relevant information about the adjacent restoration site. NCDMS' Little Sebastian site is now out on Public Notice, SAW -2017-01507, dated September 21, 2017. The Mitigation Plan should address how the Gideon Site will tie in with the adjacent restoration work so that the projects connect seamlessly and minimize disturbance to one another. • Section 5.4.7/Page 13: Be sure to identify the adjacent restoration work at the Little Sebastian site upstream and downstream of the project as a potential constraint. See comment above. • Section 5.5/Page 14: Table 6 does not match Figure 8. Be sure not to carry error forward into the Mitigation Plan for Gideon Site. • Section 5.5.1/Page 14: Second paragraph should state Enhancement Level II instead of Level I. 1 also recommend 50 -foot riparian buffers be considered for this site due to the high potential for nutrients and fecal pathogens to enter the stream from the adjacent pasture. • Section 7.1/Page 21: SMU discrepancy should be corrected to match Table 6 on page 26. • Section 7.4.2/Page 22: Information on FF -5 is missing. • Section 7.5.1/Page 26: Enhancement Level I is not being utilized at the Green Mesa Site. Level II is proposed for Reach FF3-A. • Section 8.5.1/Page 34: Priority Level I is proposed for TC3-13 only. Be sure to note pond removals in this paragraph and restoration plan in general. • Section 8.5.1/Page 35: Enhancement Level II includes TO -A also. • Section 9.1/Page 36: Recommend continuing to coordinate with NCDMS and the adjacent Mockingbird site currently out on Public Notice (SAW -2017-01505) dated September 15, 2017. The Mockingbird site is considering a Priority II approach to restoration along Hauser Creek at the terminus of the Scout Site which is considering Priority I approach on Hauser Creek (HC3). I agree that the sites can be developed independently but they should complement each other and provide for a seamless transition as one moves downstream from Scout to Mockingbird. • Section 9.4.7/Page 39: See comment above. Thank you for the opportunity to provide feedback, comments and concerns with the RES Yadkin 01 Umbrella Mitigation Bank Prospectus and associated proposed sites to provide compensatory mitigation in the Upper Yadkin River watershed of North Carolina. I believe the sponsor has provided a viable plan to offset warm and cool water stream impacts that will be incurred within the proposed service area.

The proposed project involves the restoration, enhancement, and preservation of approximately 8,350 linear feet of stream. The prospectus for the RES Yadkin 01 Stream Umbrella Mitigation Bank was submitted to the NC Interagency Review (IRT) Team in July 2017. As part of that process SHPO responded on November 7, 2017 that a review of the project has been conducted and are not aware of any historic resources which would be affected by the project (Tracking #ER17-1991). The five sites under the proposed RES Yadkin 01 Umbrella Bank had IRT site visits October 16-18, 2017. During the site visit it was noted that the Green Mesa Site has two stone walls that would need further coordination with SHPO. One stone wall is located on Reach FF1-C (north of the pond) and this entire wall is intact and has a culvert. It was noted during the site visit to possibly retrofit this culvert, but the IRT and RES agreed to leave the culvert in place and adjust the credit ratio. The mitigation treatment on this reach is Enhancement II and would involve cattle exclusion and riparian buffer planting. There will not be any earthwork or equipment in this area. The other stone wall is remnants of a stone wall on Reach FF1-A (reach to the farthest west). The mitigation treatment on this reach is also Enhancement II with an approach of cattle exclusion and riparian buffer planting. There will not be any earthwork or equipment in this area. These two areas are called out on the attached map and photos of both areas are included in this letter. If you would like the regular size photo for any of these please let me know. The landowners have lived on the property for four generations. The current landowner, Arlene Frazier said her great grandfather (Duke Frazier) helped build the lower dam crossing with paid laborers on Reach FF1-C. It was built as a creek crossing and the driveway crossed it until the USACE dam was built. The current landowners do not have any information about the dam/stone wall remnants on Reach FF1-A.

After our initial review request was sent to SHPO we had a follow- up site visit with the stream engineer and there is some proposed minor bank stabilization work to be done on Reach FF1-A to prevent future erosion and instability. The proposed work would involve grading the banks and there are three proposed spots for this. Page 3 of the attached PDF shows the zoomed in area on Reach FF1-A (this was in original correspondence). One area is about 75 feet upstream of the wall on the opposite side of the stream bank (the wall is on the left bank and the proposed grading is on the right bank). Another spot is about 75 downstream of the wall and we'd be smoothing the banks. The third spot is about 400 feet downstream of the wall and would involve grading the banks. The stone wall remnants would not be impacted and no work is proposed immediately in the vicinity of the wall (75 feet away). Please let me know if you need any additional information.

We have reviewed the information provided and offer the following comments. One dry -stacked stone wall feature (31YD224) is located in Reach FF1-A of the subject mitigation site. Based on the information provided, earthwork will take place 75 feet from 31YD224, but not in the immediate vicinity of the wall itself. We find this 75 -foot distance sufficient to buffer site 31YD224 from disturbance associated with the proposed stream bank grading. Therefore, the proposed mitigation activities will have no effect on any historic properties eligible for listing in the National Register of Historic Places.
