Axiom Environmental, Inc. 218 Snow Avenue Raleigh, North Carolina 27603 Contact: Grant Lewis 919-215-1693 (phone) "This mitigation plan has been written in conformance with the requirements of the following: • Federal rule for compensatory mitigation project sites as described in the Federal Register Title 33 Navigation and Navigable Waters volume 3 Chapter 2 Section § 332.8 paragraphs (c)(2) through(c)(14). • NCDEQ Division of Mitigation Services In -Lieu Fee Instrument signed and dated July 28, 2010 These documents govern NCDMS operations and procedures for the delivery of compensatory mitigation." This document was assembled using the June 2017 DMS Stream and Wetland Mitigation Plan Template and Guidance and the October 24, 2016 NC Interagency Review Team Wilmington District Stream and Wetland Compensatory Mitigation Update. Slingshot Mitigation Plan Comment Responses: DWR Comments, Mac Haupt and Erin Davis: This site is in the Jordan Lake watershed, are there any plans to pursue riparian buffer or nutrient offset strategy? • No, RS has not been contracted by DMS for buffer or nutrient credits. 2. The number of crossings for the size of the site is a negative aspect of this site. Is there any way at least one crossing could be removed? • No, the conservation easement has already been recorded. The farthest downstream crossing was originally 45' in width and scaled down to a 25' width based on the IRT field notes. The additional crossings are required by the landowner. 3. Section 3.5- DWR noted that there is only one soil profile boring listed in the Appendix. Given that this site has wetland restoration credit, a much more thorough soil characterization will need to occur before DWR will approve the proposed wetlands in this mitigation plan. During the site visit, DWR field notes stated that many of our soil cores did not see lower chromas required for hydric soils. • Additional soil profiles have been added to the appendix, with the locations depicted on Figure 4. 4. Section 8.1.1- Outfall Structures- DWR does not support the use of the Terracell drop structure. DWR prefers the utilization of natural materials in the channel bed. Moreover, DWR does not believe the slope change is so drastic that the artificial structure is warranted. • Terracel has been changed to Drop Structure in Figure 513, Figure 713, and in the text of the document. 5. Section 8.3- Wetland Restoration — the plan states that, "...the construction of ephemeral pools will add an important component to groundwater restoration activities. These activities will result in the restoration of 1.02 acres of jurisdictional ....riverine wetlands." DWR would like to stress that if ephemeral pools are counted as wetland restoration then they will need to be constructed so that there is periodic drying. • Ephemeral pools will be constructed such that they dry during the summer and will have woody debris habitat incorporated into the feature. 6. Table 14 Planting Plan- DWR is recommending a cap of 5% in the planting of Green Ash due to the green ash borer. • The planting list has been updated to include species ordered for the Site. The final planting list includes 400 green ash, which is less than 4% the total number of planted stems. 7. Table 16- Monitoring Table-DWR requires a stream gauge on UT3 in the upper third of the reach. • This is an EII reach added by the IRT/DMS. As the channel was identified by the IRT, confirmed to be a stream by NCDWR and the Corps of Engineer during a PDJ, and no channel alternation work is to be conducted within, or adjacent to the channel, we respectfully request to leave this gauge off the monitoring protocol for the Site. 8. Table 16- DWR likes the fact that benthic macroinvertebrates will be monitored. • Good. 9. From a landscape position standpoint, DWR would rather not have mitigation sites draining (in close proximity) into ponds or lakes. • This is an unavoidable aspect of this Site and was discussed during our initial Site visit. Note: Downstream, Lake Reidsville, is a municipal drinking water source for the Town of Reidsville and the local government is very appreciative of the project for the water quality benefit. 10. Figure 513- there are areas which appear to be in green where the current channel exists. Are these areas meant to be proposed for wetland restoration credit? If these areas are proposed for wetland credit, DWR believes restoration credit may not be appropriate. RS has successfully performed and received R credit in old stream channels in the past. We have data from many similar projects that shows that these areas are successfully converted back to wetlands. 11. DWR notes that there were no photos of the site in the mitigation plan. It is often beneficial in the review of the document to have the photos, especially if it has been awhile since the site visit. In addition, DWR would like to see photos associated with the cross sections (Appendix B) if at all possible. • Appendix J has been added to the document and contains Site photographs. Photographs of existing conditions cross sections is not available. 12. Design sheet 2C- shows an engineered riffle with rip rap being placed on the bank slope. DWR does not approve of rip rap being placed on the banks. • This has been removed from the plans set. 13. Design sheet 4- DWR needs to see a scale on these sheets. Also, the thick dashed black line, is that limits of disturbance? DWR prefers that significant markings on the plan view be clearly labeled. • Completed 14. Design sheet 8- DWR does not believe the utilization of a Terracell structure is warranted when the rest of the project was using log cross vanes. • Terracel has been changed to Drop Structure in Figure 513, Figure 713, and in the text of the document. 15. Design sheet E2- What activities will be done to return the areas utilized as haul roads back to natural conditions? • See construction notes, these will be added to the haul road sheets. 16. What percentage of this project has less than 50 foot buffers? UT 4 has less than a 50-foot buffer on its right bank, as it enters the property. UT 4 is a preservation reach and accounts for less than 2% of the buffer area. All other streams have a minimum 50-foot buffer on both stream banks. USACE Comments, Kim Browning: 17. The correct USACE Action ID is SAW-2018-01170. Please correct the cover page. • The USACE Action ID has been updated. 18. Please depict photo points/digital image stations on Figures 10. If the fixed cross-section locations are to be used, please describe that in the text in section 7.1. • A note was added to Table 15 indicating the following. "Visual Assessment will be complimented by permanent photographic points located at each permanent cross section and vegetation plot." 19. Section 8.3- Wetland Restoration — The inclusion of ephemeral/vernal pools is acceptable, and should be 8-14" depressions that dry up yearly so that predatory species cannot colonize. • Ephemeral pools will be constructed no deeper than 12 inches, will incorporate woody debris for habitat, and will be expected to dry during summer months. 20. This section also discusses filling drainage ditches. If ditches are to be filled, please show these areas on the construction plans, and the length of the ditch plug. • Channel plugs will be added to the construction plans. 21. It would be beneficial to add some coarse woody debris to the depressional areas in the buffers and throughout the adjacent wetlands for habitat, and to help store sediment, increase water storage/infiltration, and absorb water energy during overbank events. • Woody debris will be included as small piles in the riparian and wetland areas for habitat. 22. Please discuss how fescue will be treated within the buffer establishment area. RS acknowledges that this site does face challenges based on the existing vegetation. These challenges will be overcome through a combination of herbicide applications and mechanical site prep techniques. Preliminary herbicide treatments have already been made targeting woody non-native invasive species (NNIS) including Kudzu, Tree of Heaven, Privet, and Multiflora Rose (September 2019) both within the site boundaries and along the margins of the site on the parent tract. An additional herbicide treatment for privet and fescue is planned before the end of 2019 (pre -construction). During construction mechanical site prep techniques including ripping will be used to diminish any remaining undesired pasture grasses and facilitate tree establishment. The planned permanent seed mix will also mitigate the regrowth of fescue by including cool season forbs. After construction a regular herbicide program will be implemented targeting both dense pasture grasses and NNIS. This integrated approach will provide a high level of control of fescue and other undesired species and will support establishment of the desired hardwood forest community. 23. UT3- should have a flow gauge in the upper third of the reach. • This is an EII reach added by the IRT/DMS. As the channel was identified by the IRT, confirmed to be a stream by NCDWR and the Corps of Engineer during a PDJ, and no channel alteration work is to be conducted within, or adjacent to the channel, we respectfully request to leave this gauge off the monitoring protocol for the Site. 24. Section 7.0- Potential constraints... the last sentence is unclear. Section 7.0 was altered to clarify work conducted for the document. 25. Table 1- Are additional credits for macroinvertebrate sampling being sought? If so, please clarify this table. RS is not seeking extra credit for macroinvertebrate sampling on this project. 26. Table 16- Will fixed photo points be monitored annually? If so, please indicate if they will be at all cross- sections, or depict on monitoring map. • A note was added to Table 15 indicating the following. "Visual Assessment will be complimented by permanent photographic points located at each permanent cross section and vegetation plot." 27. Table 17 Success CriteriaStreams, please add a statement (regarding UT3) at least 30-days continuous surface water flow for intermittent streams. • The statement was added to Table 17 Success Criteria for streams. 28. Stream restoration will bisect existing wetlands where Slingshot Creek intersects with GA Wetland, and where UT intersects with GE Wetland. At least one wetland gauge should be installed in wetland GE to ensure no functional loss. • An additional groundwater gauge was added to Wetland GE to ensure no functional loss. In addition, Table 16 was updated to include 10 groundwater gauges, instead of 9 groundwater gauges. 29. Figure 3 in the JD —All streams are referred to as Troublesome Creek. Isn't this Slingshot Creek? Was this what it was called when proposed as a bank site? Please use consistent labeling throughout the review period, and it's especially important for the PCN to track impacts. • During our NCDMS review it was requested we change the name from Troublesome Creek (as designated in the PJD submittal) to Slingshot Creek. 30. When submitting the PCN, please include an estimate of the number of trees, or acres, to be cleared for the NLEB 4(d) Rule. • We will include an estimate of the number of trees, or acres to be cleared in our PCN submittal. 31. Table 14--Please confirm that one target community is being proposed for the entire Project Site (stream side, wetland, and upland areas). If multiple planting zones are proposed, please show zones on a figure/design sheet and reference in the planting table. • Figures 8A and 8B (Planting Plan) depict the locations of planting zones and the number of species to be planted within each planting zone. The table depicted in the figures match Table 14 in the document, which specifies species and number of seedlings to be planted in each planting zone.

The Site is located approximately 2 miles west of Reidsville, just east of Lake Hunt, and north NC Highway 158 in Rockingham County (Figures 1 and 2, Appendix A). 1.1 Directions to Site Directions to the Site from Raleigh, North Carolina. ➢ From Raleigh travel west on I-40 for 45 miles, ➢ Take exit 148 onto NC-54W toward Graham/Chapel Hill and turn right onto Harden Street, ➢ Travel 1.6 miles, then turn right onto NC-87 N/W Elm Street, ➢ After 5 miles, turn right onto NC-87 N/Ossipee Road, ➢ Travel 19.3 miles, then turn left and stay on NC-87 N, ➢ After 4.1 miles, turn left toward US-158, then turn left onto US-158 W, ➢ After 0.9 mile, take a slight right onto Iron Works Road, then take a right onto Harbor Road, ➢ The Site is located north of the end of Harbor Road. o Site Latitude, Longitude 36.334687°N, 79.711665°W (WGS84) 1.2 USGS Hydrologic Unit Code and NCDWR River Basin Designation The Site is located within the Cape Fear River Basin in 14-digit United States Geological Survey (USGS) Cataloging Unit and Targeted Local Watershed 03030002010010 of the South Atlantic/Gulf Region (North Carolina Division of Water Resources [NCDWR] subbasin number 03-06-01) [Figures 1 and 2, Appendix A]). Topographic features of the Site unnamed tributaries to Troublesome Creek (Lake Hunt), which has been assigned Stream Index Numbers 16-6-2-(1), and a Best Usage Classification of WS-III, B, NSW (NCDWR 2013). Site tributaries are not listed on the final 2016 NC 303(d) lists (NCDWR 2018). 1.3 Physiography and Land Use The Site is located in the Northern Inner Piedmont Ecoregion of the Piedmont Physiographic Province within Rockingham County, North Carolina. Regional physiography is characterized by dissected irregular plains, low to high hills, ridges, and isolated monadnocks. Streams are low to moderate gradient with mostly cobble, gravel, and sand substrates (Griffith et al. 2002). Onsite elevations range from a high of 780 feet National Geodetic Vertical Datum (NGVD) at the upper reach of Slingshot Creek to a low of approximately 740 feet NGVD at the Site outfall (USGS Reidsville, North Carolina 7.5-minute topographic quadrangle) (Figures 1 and 3, Appendix A). The Site provides water quality functions to an approximately 0.42-square mile (270-acre) watershed at the outfall; Site tributary watershed sizes range from 0.01 square mile (9 acres) to 0.10 square miles (65 acres) (Figure 3, Appendix A). The watershed is dominated by pasture, agricultural land, and sparse residential property. Impervious surfaces account for less than 5 percent of the upstream watershed land surface. Mitigation Plan (Project No. 100058) page I Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 Land use at the Site is characterized by livestock pasture, hay fields, and disturbed forest. Livestock have unrestricted access to Site streams. A narrow riparian fringe has developed on the stream margins that is composed of opportunistic species, invasive species, and a few mature tree species. 1.4 Project Components and Structure The Site encompasses 11.6 acres along warm water, unnamed tributaries to Troublesome Creek (Lake Hunt). In its current state, the Site includes 3944 linear feet perennial stream and 172 linear feet of intermittent stream (based on the approved PJD), 0.69 acre of degraded wetland, and 1.02 acre of drained hydric soil (Figure 4, Appendix A). Proposed Site restoration activities include the construction of meandering, E/C-type stream channel resulting in 2501 linear feet of Priority I stream restoration, 587 linear feet of stream enhancement (Level I), 635 linear feet of stream enhancement (Level II), 391 linear feet of stream preservation, 1.018 acre of riparian wetland restoration, and 0.606 acre of riparian wetland enhancement (Table 1) (Figures 5A-513, Appendix A). Completed project activities, reporting history, completion dates, project contacts, and background information are summarized in Tables 1-4.

More specifically, considerations included: desired aquatic resource functions; hydrologic conditions; soil characteristics; aquatic habitat diversity; habitat connectivity; compatibility with adjacent land uses; reasonably foreseeable effects the mitigation project will have on ecologically important aquatic and terrestrial resources; and potential development trends and land use changes. Site specific characteristics are summarized below, in addition to development trends and land use changes within the watershed. Currently, the proposed Site is characterized by disturbed forest, hay fields, and livestock pasture. A summary of existing Site characteristics in favor of proposed stream and wetland activities include the following. Mitigation Plan (Project No. 100058) page 7 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 • Streams and wetlands are accessible to livestock • Stream banks are trampled by livestock • Streams and wetlands have been cleared of forest vegetation • Site receives nonpoint source inputs including agricultural chemicals and livestock waste • Wetland soils have been compacted by livestock and agricultural equipment • Wetland hydrology has been removed by stream channel entrenchment • Streams are classified as nutrient sensitive waters In addition to the opportunity for ecological improvements at the Site, the use of the particular mitigation activities and methods proposed in the Design Approach & Mitigation Work Plan (Section 8.0) are expected to produce naturalized stream and wetland resources that will be ecologically self-sustaining, requiring minimal long-term management (Long-term Management Plan [Section 11.0]). Development Trends and Land Use Changes in Cape Fear 03030002 (Cape Fear 02) Between the 2000 and 2010 censuses, the Cape Fear 02 population increased approximately 17 percent. These data suggest land development activities will increase in frequency, as will aquatic ecosystem impacts related to such development. Therefore, there is an immediate and prolonged need for compensatory stream mitigation in the watershed. Of further benefit, aquatic ecosystem restoration projects are capable of reducing nutrient loading in sensitive downstream receiving waters such as Jordan Lake. According to the Cape Fear River Basinwide Water Quality Plan (NCDWQ 2005), all land uses and discharges of wastewater and stormwater in the Cape Fear 02 subbasin 03-06-01 potentially contribute nutrients to B. Everett Jordan Lake. B. Everett Jordan Lake provides low -flow augmentation, flood control, recreation, fish and wildlife habitat, and water supply. The lake is impaired for aquatic life due to excessive levels of chlorophyll a in violation of current standards in all segments of the reservoir. In addition, the Site has a supplemental water quality classification of Nutrient Sensitive Waters, which designates areas with water quality problems associated with excessive plant growth resulting from nutrient enrichment. The proposed mitigation activities will reduce sediment and nutrient levels, and improve water quality within the Site and downstream watersheds. Mitigation Plan (Project No. 100058) page 8 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 The project is located within the Troublesome Creek and Little Troublesome Creek Local Watershed Planning area (NCEEP 2004); the project activities address priorities associated with the LWP as follows with Site specific information following the LWP goals in parenthesis. 1. Protect and improve water quality by restoring wetland, stream, and riparian area functions and values, which may have been, or may be, lost through historic, current, and future impacts (4114 linear feet of stream restoration/enhancement/preservation, 1.624 acres of wetland restoration/enhancement, and 11.6 acres of riparian buffer restoration/enhancement). 2. Achieve a net increase in riparian zone buffers and wetlands acreage, functions, and values (11.6 acres of riparian buffer restoration/enhancement, and increased wetland acreage by 0.934 acres). 3. Promote a comprehensive approach for the protection of natural resources (protection of the Site, streams, wetlands, and riparian buffer through a permanent conservation easement). In addition to the defined Troublesome Creek LWP goals, additional goals for the area generally revolve around reduction of stressors to water quality. Stressors and how each will be addressed by project activities is as follows. 1. Nutrient Inputs — (nutrient model [Section 3.3] - livestock removal from streams will result in a direct reduction of 474.7 pounds of nitrogen, 39.3 pounds of phosphorus per year, and 4.7 x 1011 colonies of fecal coliform; eliminate fertilizer application; and install marsh treatment areas). 2. Streambank Erosion — (sediment model [Section 3.2] — reduction of 220 tons/year after mitigation is complete). 3. Stormwater — (reduction of bank height ratio and installation of marsh treatment area will reduce stormwater pulses). 4. Disturbed Riparian Buffer — (restoration/enhancement of 11.6 acres of riparian buffer along 4114 linear feet of stream). 5. Floodplain Alteration — (elimination of straightened, entrenched streams and the removal of spoil material deposited in the floodplain). Site specific mitigation goals and objectives have been developed through the use of North Carolina Stream Assessment Method (NC SAM) and North Carolina Wetland Assessment Method (NC WAM) and are discussed further in Section 6.0 (Functional Uplift and Project Goals/Obj ectives). 3.0 BASELINE AND EXISTING CONDITIONS 3.1 Soils and Land Form Soils that occur within the Site, according to the Web Soil Survey (USDA 2017) are described in Table 5. Mitigation Plan (Project No. 100058) page 9 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 Table 5. Web Soil Survey Soils Mapped within the Site Map Unit Map Unit Name Hydric Description S mbol Classification Status This series consists of well -drained, moderately CgB2 Clifford sandy clay loam Non-hydric eroded soils found along 2-8 percent slopes.

The parent material is (Typic Fragiudults) residuum from felsic igneous or metamorphic rock. This series consists of well -drained soils found Poplar Forest sandy clay loam along 8-15 percent slopes. The parent material is PpD2 (Typic Kanhapludults) Non-hydric residuum from felsic or intermediate, high-grade metamorphic or igneous rocks high in mica content. Hydric soils and jurisdictional wetlands were delineated and mapped by a licensed soil scientist in October 26 and 27, 2017. Based on soil delineations approximately 0.69 acre of disturbed jurisdictional wetland occur within the Site boundaries. Wetlands have been disturbed by livestock grazing and clearing of vegetation within pastureland. In addition, 1.02 acre of drained hydric soil occurs within the Site boundaries. These hydric soils have been effectively drained by stream channel incision and/or relocation of stream channels to the margins of the floodplain. 3.2 Sediment Model Sediment load modeling was performed using methodologies outlined in A Practical Method of Computing Streambank Erosion Rate (Rosgen 2009) along with Estimating Sediment Loads using the Bank Assessment of Non point Sources Consequences of Sediment (Rosgen 2011). These models provide a quantitative prediction of streambank erosions by calculating Bank Erosion Hazard Index (BEHI) and Near -Bank Stress (NBS) along each Site reach. The resulting BEHI and NBS values are then compared to streambank erodibility graphs prepared for North Carolina by the NC Stream Restoration Institute and NC Sea Grant. Streambank characteristics involve measurements of bank height, angles, materials, presence of layers, rooting depth, rooting density, and percent of the bank protected by rocks, logs, roots, or vegetation. Site reaches have been measured for each BEHI and NBS characteristic and predicted lateral erosion rate, height, and length to calculate a cubic volume of sediment contributed by the Mitigation Plan (Project No. 100058) Slingshot Creek Stream and Wetland Restoration Site Rockingham County, North Carolina page 10 Restoration Systems, LLC November 2019 reach each year. Data forms for the analysis are available upon request and the data output is presented in Appendix B. Results of the model are presented in the following table. Table 6.

The equation for nutrient reduction for this model includes the following: TN reduction (lbs/yr) = 51.04 (lbs/ac/yr) x Area (ac) TP reduction (lbs/yr) = 4.23 (lbs/ac/yr) x Area (ac) Where: TN — total nitrogen; TP — total phosphorus; and Area — total area of restored riparian buffers inside of livestock exclusion fences. Equations for fecal coliform reduction for this model include the following. Fecal coliform reduction (col) = 2.2 x 10" (col/AU/day) x AU x 0.085 Where: Col - quantities of Fecal Coliform bacteria AU - animal unit (1000 lbs of livestock) Results of the NCDMS analysis indicate approximately 474.7 lbs/yr of nitrogen, 39.3 lbs/yr of phosphorus, and 4.68 x 10" col of fecal coliform/day will be reduced due to exclusion of livestock from the easement area. 3.4 Project Site Streams Streams targeted for restoration include unnamed tributaries to Troublesome Creek, which have been cleared, dredged of cobble substrate, straightened, trampled by livestock, eroded vertically and laterally, and receive extensive sediment and nutrient inputs from livestock. Approximately Mitigation Plan (Project No. 100058) page 11 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 55 percent of the existing stream channel has been degraded contributing to sediment export from the Site resulting from mechanical processes from livestock hoof shear. In addition, streamside wetlands have been cleared and drained by channel downcutting and land uses. Current Site conditions have resulted in degraded water quality, a loss of aquatic habitat, reduced nutrient and sediment retention, and unstable channel characteristics (loss of horizontal flow vectors that maintain pools and an increase in erosive forces to channel bed and banks). Site restoration activities will restore riffle -pool morphology, aid in energy dissipation, increase aquatic habitat, stabilize channel banks, and greatly reduce sediment loss from channel banks. 3.4.1 Existing Conditions Survey Site stream dimension, pattern, and profile were measured to characterize existing channel conditions. Locations of existing stream reaches are depicted in Figure 4 (Appendix A) and cross- section locations are depicted in Figure B 1 (Appendix B). Stream geometry measurements under existing conditions are summarized in Table 7 (Essential Morphology Parameters) and presented in detail in Table B 1 (Appendix B).

Mitigation Plan (Project No. 100058) page 13 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 3.4.2 Channel Classification and Morphology Stream geometry and substrate data have been evaluated to classify existing stream conditions based on a classification utilizing fluvial geomorphic principles (Rosgen 1996). Existing Site reaches are classified as unstable G-type streams with variable sinuosity. Existing Site reaches are characterized by sand substrate as the result of channel impacts including livestock trampling, channel straightening, and riparian vegetation removal. 3.4.3 Channel Evolution Site streams targeted for restoration have been channelized and are continually trampled by livestock resulting primarily in channels classified as channelized (Class II), degraded (Class III), and degraded and widened (Class IV) channels throughout the Site (Simon and Hupp 1986). 3.4.4 Valley Classification The Site is characterized by small stream, headwater, confined, alluvial valleys with approximately 20- to 100-foot floodplain valley widths. Valley slopes of restoration reaches are typical for the Piedmont region and range from 0.0176-0.0315. Typical streams in this region include C- and E- type streams with slightly entrenched, meandering channels with a riffle -pool sequence. 3.4.5 Discharge This hydrophysiographic region is characterized by moderate rainfall with precipitation averaging approximately 41.7 inches per year (USDA 1992). Drainage basin sizes range from 0.01- to 0.42- square mile. The Site's discharge is dominated by a combination of upstream basin catchment, groundwater flow, and precipitation. Based on regional curves (Harman et al. 1999), the bankfull discharge for the Site (0.01- to 0.42-square mile watershed) ranges from 3.2 to 47.8 cubic feet per second. Based on indicators of bankfull at reference reaches and on -Site, the designed channel will equal approximately 93 percent of the channel size indicated by Piedmont regional curves; this is discussed in Section 5.2 (Bankfull Verification). 3.5 Project Site Wetlands Jurisdictional wetlands/hydric soils within the Site were delineated in the field following guidelines set forth in the Corps of Engineers Wetlands Delineation Manual and subsequent regional supplements, and located using GPS technology with reported submeter accuracy (Environmental Laboratory 1987). A jurisdictional wetland delineation was completed and verbally approved by United States Army Corps of Engineers (USACE) representative David Bailey during a meeting on August 22, 2018; the signed Notification of Jurisdictional Determination can be found in Appendix D. Existing jurisdictional wetlands are depicted in light blue and green stripes, and drained hydric soils are depicted as black cross hatch on Figure 4 (Appendix A). 3.5.1 Hydrological Characterization Construction activities are expected to restore approximately 1.018 acre of drained riparian hydric soils, and enhance 0.606 acre of cleared riparian wetlands. Areas of the Site targeted for riparian Mitigation Plan (Project No. 100058) page 14 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 wetlands will receive hydrological inputs from periodic overbank flooding of restored tributaries, groundwater migration into wetlands, upland/stormwater runoff, and, to a lesser extent, direct precipitation. Hydrological impairment in drained soils has resulted from lateral draw -down of the water table adjacent to existing, incised stream channels. 3.5.2 Soil Characterization Detailed soil mapping conducted by a North Carolina Licensed Soil Scientist (NCLSS) in October 26 and 27, 2017 indicate that the Site is currently underlain by hydric soils of the Worsham Series (Figure 4, Appendix A). Wetlands have been disturbed by livestock grazing and cleared of vegetation within pastureland. These hydric soils have been effectively drained by stream channel incision or relocation of stream channels to the floodplain margins. Onsite hydric soils are grey to gley in color and are compacted and pockmarked by livestock trampling. Livestock trampling, grazing, and clearing has resulted in an herbaceous vegetative community. Groundwater springs and surface runoff contribute hydrology to these areas, although the dominant hydrological influence is the lateral draw -down of the water table adjacent to incised stream channels or streams relocated to the floodplain margins. A detailed soil profile conducted by a NCLSS is as follows; the location is depicted on Figure 4 (Appendix A). Table 8. Profile Description Depth (inches) Color Texture 0-5 10 YR 3/3 10 YR 4/1 mottles 10% Silt loam 5 - 8 10 YR 511 Loamy clay 8-14 10 YR 6/1 Sandy clay 14+ 10 YR 6/1 Loamy sand 3.5.3 Plant Community Characterization Areas proposed for wetland restoration and enhancement are primarily vegetated by fescue and opportunistic herbaceous species with very little vegetative diversity. 4.0 REFERENCE STUDIES 4.1 REFERENCE STREAMS Two reference reaches were identified for the Site. The first reference stream (Flint Rock Farm) is located approximately 6 miles southwest of the Site on an unnamed tributary to Troublesome Creek. The second reference stream (Caswell Game Land) is located approximately 25 miles east of the Site on unnamed tributaries to South Country Line Creek. 4.1.1 Channel Classification The streams were measured and classified by stream type (Rosgen 1996). The reference reaches are characterized as E-type and Cg-type streams; Flint Rock Farm is a moderately sinuous (1.22) channel dominated by sand substrate and Caswell Game Land had slightly lower sinuosity, due to a higher valley slope, with a gravel -dominated substrate. Mitigation Plan (Project No. 100058) page 15 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 4.1.2 Discharge Field indicators of bankfull predict an average discharge of 24.4 and 71.7 cfs, respectively for the Flint Rock Farm and Caswell Game Lands reference reaches, which is 50 and 110 percent of that predicted by the regional curves. 4.1.3 Channel Morphology Dimension: Data collected at Flint Rock Farm and Caswell Game Land indicate bankfull cross - sectional areas of 6.1 and 17.6 square feet, respectively. Flint Rock Farm was significantly smaller than the regional curves (12.1 square feet) and Caswell Game Land was slightly larger than predicted by regional curves (16.0 square feet). Flintrock Farm may not be a suitable reference site for determination of cross -sectional area; however, the channel is very stable and was useful in determination of pattern and slope ratios for design calculation. Flint Rock Farm and Caswell Game Land exhibit a bankfull width of 7.5 and 18.4, a bankfull depth of 0.8 and 1.0 feet, and width -to -depth ratios of 9.6 and 19.6, respectively (see Table B 1, Morphological Stream Characteristics). The reference reaches exhibit a bank -height ratio of 1.0 and 1.8, respectively. The Caswell Game Land reference reach was slightly incised; however, defined bankfull indicators were present, which assisted with determining the appropriate cross -sectional area. Pattern and Profile: In -field measurements of the reference reaches have yielded an average sinuosity of 1.22 at Flint Rock Farm and 1.14 at Caswell Game Land (thalweg distance/straight- line distance). Onsite valley slopes of Site restoration reaches range from 0.0176-0.0315. Valley slopes exhibited by reference channels range are characterized by similar slopes (0.0060 at Flintrock Farm and 0.0114 at Caswell Game Lands), providing a good range of slopes to compare existing and proposed Site conditions. Although slightly incised, the Caswell Game Land reference reach had a suitable pattern with no shoot cutoffs, eroding outer bends, or excessively tight radius of curvatures, in addition to appropriate pool -to -pool spacing and meander wavelengths. Substrate: Reference channels are characterized by substrate dominated by gravel and sand sized particles, respectively. 4.2 Reference Forest Ecosystem A Reference Forest Ecosystem (RFE) is a forested area on which to model restoration efforts at the Site in relation to soils and vegetation. RFEs should be ecologically stable climax communities and should be a representative model of the Site as it likely existed prior to human disturbances. Data describing plant community composition and structure should be collected at the RFEs and subsequently applied as reference data in an attempt to emulate a natural climax community. The RFE for this project is located at the Abbey Lamm Stream and Wetland Mitigation Site. The RFE supports plant community and landform characteristics that restoration efforts will attempt to emulate. Tree and shrub species identified within the reference forest and outlined in Table 9 will be used, in addition to other relevant species in appropriate Schafale and Weakley (1990) and Schafale (2012) community descriptions.

Reference reach values for stream power and shear stress are slightly lower than the Site due to flatter valley and water surface slopes resulting in lower stream power and shear stress values. Existing, Site streams are characterized by a wide range of water surface slopes and varying degrees of degradation. In general, stream power values of existing streams are slightly elevated as compared to proposed values, and shear stress values of existing streams are significantly elevated as compared to proposed and reference reach values. Proposed stream power and shear stress values appear adequate to mobilize and transport sediment through the Site, without aggradation or erosion on proposed stream banks. Important input values and output results (including stream power, shear stress, and per unit shear power and shear stress) are presented in Table 10. Results of the analysis indicate the proposed channel reaches are expected to maintain stream power as a function of width values of approximately 2.89-3.77 lbs/sec3 and shear stress values of approximately 0.64-0.82 lbs/ft2 (Table 10).

For this study, the bankfull channel is defined as the channel dimensions designed to support the "channel forming" or "dominant" discharge (Gordon et al. 1992). Based on available Piedmont regional curves, the predicted bankfull discharge for the reference reaches averages approximately 48.4 and 65.2 cubic feet per second (cfs) for Flint Rock Farm and Caswell Game Land, respectively (Harmen et al. 1999). The USGS regional regression equation for the Piedmont region indicates that bankfull discharge for the reference reaches at a 1.3-1.5 year return interval average approximately 38-68 and 66-89 cfs, respectively (USGS 2006). Field indicators of bankfull, primarily topographic breaks identified on the banks, and riffle cross - sections were utilized to obtain an average bankfull cross -sectional area for the reference reaches. The Piedmont regional curves were then utilized to plot the watershed area and discharge for the reference reach cross -sectional area. Field indicators of bankfull approximate an average discharge of 24.4 and 71.7 cfs, respectively for the reference reaches, which is 50 and 110 percent of that predicted by the regional curves. Ultimately, on -site and reference cross sections with good indicators of bankfull cross sectional areas should match close to the regional curves, which is verified by the range approximated by the USGS regional regression equation. Based on the above analysis of methods to determine bankfull discharge, proposed conditions at the Site will be based on reference reaches and onsite indicators of bankfull (UT 1 cross -sections 3 and 7, Appendix B). Based on field indicators of bankfull at the Site (93 percent of the curves), Mitigation Plan (Project No. 100058) page 18 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 and the Reference Reaches, the designed onsite channel restoration area will equal approximately 93 percent of the channel size indicated by Piedmont regional curves. Therefore, Site bankfull discharges range from approximately 15.5-44.4 cfs. Table 11 summarizes all methods analyzed for estimating bankfull discharge. Table 11.

The RBRP report documents benthic ratings vary between "Fair" and "Good - Fair" possibly due to cattle, dairy, and poultry operations. The project is located within the Troublesome Creek and Little Troublesome Creek Local Watershed Planning area (NCEEP 2004); project activities address priorities associated with the LWP as follows with Site specific information following the LWP goals in parenthesis. 1. Protect and improve water quality by restoring wetland, stream, and riparian area functions and values, which may have been, or may be, lost through historic, current, and future impacts (4115 linear feet of stream restoration/enhancement/preservation, 1.71 acres of wetland restoration/enhancement, and 11.6. acres of riparian buffer restoration/enhancement). 2. Achieve a net increase in riparian zone buffers and wetlands acreage, functions, and values (11.6 acres of riparian buffer restoration/enhancement, and increased wetland acreage by 1.02 acres). 3. Promote a comprehensive approach for the protection of natural resources (protection of the Site, streams, wetlands, and riparian buffer through a permanent conservation easement). Mitigation Plan (Project No. 100058) page 19 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 In addition to the defined Troublesome Creek LWP goals, additional goals for the area generally revolve around reduction of stressors to water quality. Stressors and how each will be addressed by project activities is as follows. 1. Nutrient Inputs — (nutrient model [Section 3.3] - livestock removal from streams will result in a direct reduction of 474.7 pounds of nitrogen, 39.3 pounds of phosphorus per year, and 4.7 x 1011 colonies of fecal coliform; eliminate fertilizer application; and install marsh treatment areas). 2. Streambank Erosion — (sediment model [Section 3.2] — reduction of 220 tons/year after mitigation is complete). 3. Stormwater — (reduction of bank height ratio and installation of marsh treatment area will reduce stormwater pulses). 4. Disturbed Riparian Buffer — (restoration/enhancement of 11.6 acres of riparian buffer along 4115 linear feet of stream). 5. Floodplain Alteration — (elimination of straightened, entrenched streams and the removal of spoil material deposited in the floodplain). Site specific mitigation goals and objectives have been developed through the use of North Carolina Stream Assessment Method (NC SAM) and North Carolina Wetland Assessment Method (NC WAM) analyses of existing and reference stream systems at the Site (NC SFAT 2015 and NC WFAT 2010). These methodologies rate functional metrics for streams and wetlands as high, medium, or low based on field data collected on forms and transferred into a rating calculator. Using Boolean logic, the rating calculator assigns a high, medium, or low value for each metric and overall function. Site functional assessment data forms are available upon request and model output is included in Appendix B. Tables 12A and 12B summarize NC SAM and NC WAM metrics targeted for functional uplift and the corresponding mitigation activities proposed to provide functional uplift. Metrics targeted to meet the Site's goals and objectives are depicted in bold.

The evaluation focused primarily on the presence of hazardous materials, utilities and restrictive easements, rare/threatened/endangered species or critical habitats, and the potential for hydrologic trespass. Existing information regarding Site constraints was acquired and reviewed. In addition, field surveys were conducted to confirm if constraints occur within, or adjacent to the Site boundaries. No known Site constraints that may hinder proposed mitigation activities were identified during background research or field surveys. Potential constraints reviewed include the following. 7.1 Threatened & Endangered Species Three federally protected species are listed as occurring in Rockingham County (USFWS 2018); the following table summarizes potential habitat and preliminary biological conclusions for each. Table 13. Threatened and Endangered Species Species Habitat Potential Biological Habitat at Site Conclusion This freshwater mussel is limited to the James River drainage and the Dan/Mayo James spinymussel River drainage within the Roanoke River (Pleurobema collina) basin in Virginia, North Carolina, and West No No Effect Virginia. This species' range does not include the Site, which is located in the Upper Ca e Fear River drainage. In North Carolina, this species is found in Roanoke logperch the Dan and Mayo rivers, as well as Big (Percina rex) Beaver Island Creek. This species' range No No Effect does not include the Site, which is located in the Up er Cape Fear River drainage. This species grows in calcareous, basic, or circumneutral soils on roadsides, clear cuts, Smooth coneflower and power line right-of-ways where there is (Echinacea laevigata) abundant light and little herbaceous Yes No Effect* competition. Fire -maintained woodlands also appear to provide potential habitat for the coneflower. *Detailed field surveys for this species were conducted during the optimum survey window. Survey methodology and results are included in Appendix E. Neither the James spinymussel nor the Roanoke logperch have ranges that extend into areas adjacent to or within the Site; therefore, this project will have no effect on these federally protected species. Suitable habitat for the smooth coneflower exists at the Site; therefore, surveys were conducted in May 2018, during the optimal survey window for this plant. Correspondence concerning survey methodology and results are presented in Appendix E. 7.2 Cultural Resources The term "cultural resources" refers to prehistoric or historic archaeological sites, structures, or artifact deposits over 50 years old. "Significant" cultural resources are those that are eligible or Mitigation Plan (Project No. 100058) Slingshot Creek Stream and Wetland Restoration Site Rockingham County, North Carolina page 24 Restoration Systems, LLC November 2019 potentially eligible for inclusion in the National Register of Historic Places. Evaluations of site significance are made with reference to the eligibility criteria of the National Register (36 CFR 60) and in consultation with the North Carolina State Historic Preservation Office (SHPO). Field visits were conducted at the Site late 2017 to ascertain the presence of structures or other features that may be eligible for inclusion on the National Register of Historic Places. No structures were identified within proposed easement boundaries; however, coordination with State Historic Preservation Office will occur prior to construction activities to determine if any significant cultural resources are present. 7.3 North Carolina Natural Heritage Elements A query of the North Carolina Natural Heritage Program (NCNHP) database indicates there are no records for rare species, important natural communities, natural areas, or conservation/managed areas within the proposed project boundary. Within a one -mile radius of the project boundary NCNHP lists an element occurrence, a natural community, and a natural area, which are summarized in the NCNHP correspondence in Appendix E. In addition, North Carolina Division of Mitigation Services (NCDMS) Sharpe property wetland preservation Site is located within close proximity of the Site. 7.4 FEMA Inspection of the FEMA Flood Insurance Rate Map 3710798400J, Panels 7984 and 7994, effective September 3, 2007, indicates that Site streams are not located in a Special Flood Hazard Area, and the project should not alter FEMA flood zones. Therefore, a "Conditional Letter of Map Revision" (CLOMR) is not necessary for this project. 7.5 Utilities No utilities are located on the Site. 7.6 Air Transport Facilities One air transport facility is located within 5 miles of the Site. Warf Airfield is located approximately 0.5 mile south of the Site. 8.0 DESIGN APPROACH AND MITIGATION WORK PLAN 8.1 Stream Design Onsite streams targeted for restoration have endured significant disturbance from land use activities such as land clearing, livestock grazing, straightening and rerouting of channels, and other anthropogenic maintenance. Site streams will be restored to emulate historic conditions at the Site utilizing parameters from nearby, relatively undisturbed reference streams (see Section 4.1 Reference Streams). Primary activities designed to restore Site streams include 1) stream restoration, 2) stream enhancement (Level I), 3) stream enhancement (Level II), 4) stream preservation, 5) wetland restoration, 6) wetland enhancement, and 7) vegetation planting (Figures 5A-513, Appendix A). Mitigation Plan (Project No. 100058) page 25 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 8.1.1 Stream Restoration Stream restoration efforts are designed to restore a stable stream that approximates hydrodynamics, stream geometry, and local microtopography relative to reference conditions. Restoration at the Site will be Priority I restoration; therefore, bankfull elevations will be raised to meet the adjacent valley floodplain elevation. Stream restoration is expected to entail 1) channel excavation (Figure 6, Appendix A), 2) spoil stockpiling, 3) channel stabilization, 4) channel diversion, and 5) channel backfill. In -stream Structures The use of in -stream structures for grade control and habitat is essential for successful stream restoration (Figure 7A, Appendix A). In -stream structures may be placed in the channel to elevate local water surface profiles in the channel, potentially flattening the water energy slope or gradient and directing stream energy into the center of the channel and away from banks. The structures will consist of log cross -vanes or log j-hook vanes; however, at the discretion of the Engineer, rock cross -vanes or rock j-hook vanes may be substituted if dictated by field conditions. In addition, the structures will placed in relatively straight reaches to provide secondary (perpendicular) flow cells during bankfull events. Piped Channel Crossings Landowner constraints will necessitate the installation of 4 piped channel crossings within breaks in the easement to allow access to portions of the property isolated by stream restoration activities. The crossings may be constructed of properly sized pipes and hydraulically stable rip -rap or suitable rock. Crossings will be large enough to handle the weight of anticipated vehicular traffic. Approach grades to the crossing will be at an approximate 10:1 slope and constructed of hard, scour -resistant crushed rock or other permeable material, which is free of fines. Outfall Structures One drop structure is proposed at the outfall of Slingshot Creek. The drop structure may be constructed out of large cobble depending upon anticipated scour from the restored stream channels (Figure 713, Appendix A). The structure should be constructed to resist erosive forces associated with hydraulic drops proposed at the Site. Marsh Treatment Areas No areas of concentrated flow have been identified at this time; however, if during construction a point of concentrated flow is identified then a shallow wetland marsh treatment area will be excavated in the floodplain to intercept surface waters draining through agricultural areas prior to discharging into the Site. Marsh treatment areas are intended to improve the mitigation project and are not generating mitigation credit. The proposed marsh treatment area will consist of shallow depressions that will provide treatment and attenuation of initial stormwater pulses (Figure 713, Appendix A). The outfall will be constructed of hydraulically stable rip -rap or other suitable material that will protect against headcut migration into the constructed depression. It is expected that the treatment area will fill with sediment and organic matter over time. Mitigation Plan (Project No. 100058) page 26 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 8.1.2 Stream Enhancement (Level 1) Stream enhancement (level I) will occur on reaches accessible by livestock. Stream dimension will be restored in these reaches, fencing will be erected to exclude livestock, and planting riparian buffers with native forest vegetation will occur where needed. 8.1.3 Stream Enhancement (Level 11) Stream enhancement (level II) will occur on reaches are characterized by channels with patches of mature riparian vegetation, good channel bed substrate, and little bank erosion. The reaches are accessible by livestock and will have fence erected to exclude livestock. Planting riparian buffers with native forest vegetation will occur where needed. 8.1.4 Stream Preservation Stream preservation will occur on the upstream reaches of Slingshot Creek and the entirety of UT 4. These reaches are characterized by channels with mature riparian vegetation, good channel bed substrate, and little bank erosion. The reaches are not accessible by livestock and are included in the project to protect the upstream reaches from future impacts. 8.2 Individual Reach Descriptions Mitigation strategies proposed for each reach are presented below. 8.2.1 Slingshot Creek (UT to Troublesome Creek) Slingshot Creek enters the Site from the upstream property and extends for 2920 linear feet in its current location. The upper reach of Slingshot Creek is fenced from livestock and surrounded by mature vegetation. Once the stream enters pastureland, remnants of a breached impoundment are situated across the floodplain. Livestock have impacted the channel above and below the impoundment; however, the channel retains suitable pattern. The channel descends the valley to a nick point where the channel becomes deeply incised and appears to have been dredged and straightened. Adjacent to the majority of the straightened reach, vegetation remains in successional in patches, with unmaintained pasture comprising the rest of the channel banks and floodplain. The lower reaches of channel were dredged and straightened, as evidenced by oxbow wetlands in the floodplain. This reach was historically crossed by an elevated road bed. An undersized or blocked pipe beneath the road bed appears to have failed, resulting in extensive erosion above and below the road bed. The lower reach is characterized by mature vegetation on the left bank and pasture on the right bank. In its current state, Slingshot Creek is classified as a G-type channel with entrenchment ratios averaging 1.6. Although entrenchment ratios exhibit some connection to the floodplain, the majority of the channel is incised, as evidenced by bank -height -ratios ranging from 1.3 to 4.5. Incision varies across the reach, with deep incision occurring in areas that appear to have been dredged and straightened, particularly downstream from the nick point. Dredging and straightening of the channel have resulted in a loss of riffle pool morphology. Slingshot Creek is proposed for four mitigation treatments; 1) stream restoration, 2) stream enhancement (level I), 3) stream enhancement (level II), and 4) stream preservation. Mitigation Plan (Project No. 100058) page 27 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 Stream Restoration Stream restoration is proposed for the majority of Slingshot Creek where the channel has been straightened, is deeply incised, and is heavily impacted by livestock. The reach is proposed for Priority 1 restoration on new location, reconnecting the channel to degraded/drained wetlands or hydric soils. Channel construction is expected to entail filling ditches/drainage features, installation of three piped crossings, excavating a channel that connects stream overbank events with adjacent wetlands, installation of grade control and habitat structures, and connecting the channel with downstream reaches. Stream Enhancement (Level I) Stream enhancement (level I) is proposed for the upper reaches of Slingshot Creek where channel pattern appears to exhibit suitable sinuosity and pool -to -pool spacing; however, the channel is relatively incised, impacted by livestock, and is characterized by low radius of curvature values in several bends. Mitigation in these areas will focus on elevating the stream bed, providing the proper channel dimension, and reducing shear on tight meander bends. Structures will be strategically placed to reduce pressure on channel banks and focus scour into the center of the channel. This reach will ultimately reconnect the channel to the floodplain and adjacent wetlands, and bring the channel to a suitable elevation. Stream Enhancement (Level II) The upper reaches of Slingshot Creek are proposed for stream enhancement (level II) through the removal of livestock, supplemental planting with native hardwood species, removal of remnants of a breached dam, and placement of a permanent conservation easement. Stream Preservation The upper reaches of Slingshot Creek and UT 4 are proposed for stream preservation. These areas are stable and livestock do not access the channels, or stream buffer. Preservation reaches will have invasive species treatment, fence upgrades to ensure livestock exclusion, and placement of a conservation easement. 8.2.2 UT 1 UT 1 enters the Site from the upstream property and extends for 968 linear feet in its current location. The upper reaches of UT 1 are crossed by an elevated road with a failing pipe. Currently, the upper reaches are impounded to a depth of approximately 3 feet. Stream flow overtops the road bed and is eroding the channel. A bedrock sill has reduced erosion and UT 1 maintains pattern for approximately 150 feet below the road, before the bedrock sill ends and the channel becomes incised. Historically, this reach below the bedrock sill may have been impounded, as evidenced by remnants of an earthen dam. Below the earthen dam, the channel appears to have been manipulated in the past and livestock have impacted the channel banks. The entire reach of UT 1 is surrounded by sparse mature trees and successional vegetation associated with neglected pastureland. Livestock have access to the entirety of UT 1 and channel banks are eroding from hoof shear. In its current state, UT 1 is classified as a G-type channel with entrenchment ratios averaging 2.0. Although entrenchment ratios exhibit some connection to the floodplain, the majority of the Mitigation Plan (Project No. 100058) Slingshot Creek Stream and Wetland Restoration Site Rockingham County, North Carolina page 28 Restoration Systems, LLC November 2019 channel is incised, as evidenced by bank -height -ratios ranging from 1.2 to 3.7. Incision varies across the reach, with deep incision occurring in areas downstream from the nick point. UT 1 is proposed for three mitigation treatments; 1) stream restoration, 2) stream enhancement (level I), and 3) stream enhancement (level II). During field reviews with Interagency Review Team (IRT) members it was discussed that a mix of mitigation treatments throughout the entire reach of UT was is likely to occur. However, large sections of mitigation treatment is proposed rather than many short alternating sections of mitigation treatments. Ultimately, UT 1 will include various mitigation strategies throughout each reach. Stream Restoration Stream restoration is proposed for the lower, downstream sections of UT 1 as the channel enters wetlands associated with the larger, Slingshot Creek floodplain. This reach of channel is currently incised (BHR of 2.3 and 1.6 in cross sections 1 and 2 [Appendix B]) and will be reconnected to the adjacent floodplain wetlands. In addition, as UT 1 meets Slingshot Creek floodplain the channel is proposed to be redirected across the floodplain to the natural topographic location, the lowest portion of the floodplain. The reach is proposed for Priority 1 restoration on new location. Channel construction is expected to entail excavating a channel that connects stream overbank events with adjacent wetlands, installation of grade control and habitat structures, and connecting the channel with downstream reaches. Stream Enhancement (Level I) Stream enhancement (level I) is proposed for the middle reaches of UT 1, below the bedrock sill and above the restoration reach. As stated above, this reach of channel will likely also include enhancement (level II) and restoration measures. Reaches of the channel where pattern appears to exhibit suitable sinuosity and pool -to -pool spacing, in channel manipulation of dimension and profile will be conducted. These reaches are incised; therefore, enhancement efforts are expected to rehydrate drained jurisdictional wetland within the narrow floodplain. Several tight meander bends will be eased to reduce erosion. In addition, the remnants of a historic dam will be removed to allow floodwaters to access floodplains below the dam. Mitigation in these areas will focus on elevating the stream bed, providing the proper channel dimension, and reducing shear on tight meander bends. Structures will be strategically placed to reduce pressure on channel banks and focus scour into the center of the channel. This reach will ultimately reconnect the channel to the floodplain and adjacent wetlands, and bring the channel to a suitable elevation. In addition, a piped channel crossing will be installed in the upper reaches. Stream Enhancement (Level II) The upper reaches of UT 1 are impounded by a failing road crossing/culvert. This section of stream is proposed to have the road crossing upgraded with a new, appropriately sized piped crossing and the channel constructed to the proper dimension and slope. As stated above, this reach is proposed for multiple mitigation treatments, including restoration, enhancement (level I), and enhancement (level II) and has been lumped as one mitigation treatment for discussion and crediting purposes. Mitigation Plan (Project No. 100058) page 29 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 8.2.3 UT 2 UT 2 enters the Site from the upstream property and extends for 130 linear feet in its current location. UT 2 is a relatively short reach that has been dredged and straightened. The channel is excessively deep and parallels a driveway and metal structure outside of the easement boundaries. Both banks of UT 2 are characterized as agriculture pasture, with the left bank providing a holding pen for loading cattle into trailers. In its current state, UT 2 is classified as a G-type channel with entrenchment ratios averaging 1.6. The entire reach is incised as evidenced by bank -height -ratios ranging from 2.5 to 3.9. Dredging and straightening of the channel have resulted in a loss of riffle pool morphology. UT 2 is proposed for one mitigation treatment; 1) stream restoration. Stream Restoration Stream restoration is proposed for the entirety of UT 2 which will excavation of channel on new location. Channel construction is expected to entail filling ditches/drainage features, upgrading a forded channel crossing, excavating a channel that connects stream overbank events with adjacent wetlands, installation of grade control and habitat structures, and connecting the channel with downstream reaches. 8.2.4 UT 3 UT 3 enters the Site from the upstream property and extends for 189 linear feet in its current location. UT 3 is a relatively short reach that was dredged and straightened many years ago and has naturalized in its current location. The channel has disturbed forest on its left bank and pasture on its right bank. The channel is characterized by an intermittent flow regime. Livestock have access to the entire reach. UT 3 is proposed for one mitigation treatment; 1) stream enhancement (level II). Stream Enhancement (Level II) The entire reach of UT 3 is proposed for stream enhancement (level 11) through the removal of livestock with fencing, supplemental planting with native hardwood species, and placement of a permanent conservation easement. 8.2.5 UT 4 UT 4 enters the Site from the upstream property and extends for 86 linear feet in its current location. UT 4 is a relatively short reach that is characterized by mature forest vegetation and is isolated from livestock. The IRT specified this reach for preservation credit. UT 4 is proposed for one mitigation treatment; 1) stream preservation. Stream Preservation UT 4 is proposed for stream preservation. These areas are stable and livestock do not access the channels, or stream buffer. Preservation reaches will have invasive species treatment, fence upgrades to ensure livestock exclusion, and placement of a conservation easement. Mitigation Plan (Project No. 100058) page 30 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 8.3 Wetland Restoration Wetland restoration activities are designed to restore a fully functioning wetland system, which will provide surface water storage, nutrient cycling, removal of imported elements and compounds, and will create a variety and abundance of wildlife habitat. Portions of the Site underlain by hydric soils have been impacted by drainage ditch excavation, vegetative clearing, agriculture plowing, herbicide application, and other land disturbances associated with land use management. Wetland restoration will focus on the restoration of vegetative communities, filling drainage ditches, the reestablishment of soil structure and microtopographic variations, and redirecting normal surface hydrology from streams back into the Site floodplains. In addition, the construction of (or provisions for) surface water storage depressions (ephemeral pools) will also add an important component to groundwater restoration activities. These activities will result in the restoration of 1.02 acres of jurisdictional riparian riverine wetlands. Restoration of Historic Groundwater Elevations Hydric soils appear to have been drained due to lowering of the groundwater tables and a lateral drainage effect from stream channel incision and straightening. Reconstructing streams at a natural depth, increasing stream sinuosity, and directing surface flow from adjacent properties across the ground surface is expected to rehydrate hydric soils within the Site, resulting in the restoration of jurisdictional hydrology to riparian wetlands. Hvdrophvtic Vegetation Site wetland areas have endured significant disturbance from land use activities such as land clearing, livestock trampling, herbicide application, and other anthropogenic maintenance. Wetland areas will be revegetated with native forest vegetation typical of wetland communities in the region. Emphasis will focus on developing a diverse plant assemblage. 8.4 Wetland Enhancement Wetland enhancement will focus on the removal of livestock and restoration of vegetative communities resulting in the enhancement of 0.606 acre of riparian riverine wetland. 8.5 Soil Restoration Soil grading will occur during stream restoration activities. Topsoil will be stockpiled during construction activities and will be spread on the soil surface once critical subgrade has been established. The replaced topsoil will serve as a viable growing medium for community restoration to provide nutrients and aid in the survival of planted species. 8.6 Natural Plant Community Restoration Restoration of floodplain forest and stream -side habitat allows for development and expansion of characteristic species across the landscape. Ecotonal changes between community types contribute to diversity and provide secondary benefits, such as enhanced feeding and nesting opportunities for mammals, birds, amphibians, and other wildlife. Reference Forest Ecosystem (RFE) data, onsite observations, and community descriptions from Classification of the Natural Mitigation Plan (Project No. 100058) page 31 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 Communities ofNorth Carolina (Schafale and Weakley 1990) were used to develop the primary plant community associations that will be promoted during community restoration activities. 8.6.1 Planting Plan Stream -side trees and shrubs include species with high value for sediment stabilization, rapid growth rate, and the ability to withstand hydraulic forces associated with bankfull now and overbank flood events. Stream -side trees and shrubs will be planted within 15 feet of the channel top of bank throughout the meander belt -width. Shrub elements will be planted along the reconstructed stream banks, concentrated along outer bends. Piedmont Alluvial Forest is the target community for Site floodplains and Dry-Mesic Oak -Hickory Forest is the target community for upland side -slopes. Bare -root seedlings within the Piedmont Alluvial and Dry-Mesic Oak -Hickory Forests will be planted at a density of approximately 680 stems per acre on 8-foot centers. Shrub species in the stream -side assemblage will be planted at a density of 2720 stems per acre on 4-foot centers. Table 14 depicts the total number of stems and species distribution within each vegetation association (Figures 8A and 8B, Appendix A). Planting will be performed between December 1 and March 15 to allow plants to stabilize during the dormant period and set root during the spring season. Permanent seed mixes will be planted that quickly establish a low -growing groundcover on the Site which will reduce erosion, provide streambank stability, benefit wildlife, and facilitate the successful establishment of the planned hardwood tree community. Species mix is subject to commercial availability at time of planting; however, the general diversity and function of permanent seed mix will remain. Seed mix components will include the following. Upland Seed Mix (2 lbs/ac) 1. Redtop (Agrostis alba) 2. Creeping Bentgrass (Agrostis stolonifera) 3. Winter Bentgrass (Agrostis hyemalis) 4. Purple Coneflower (Echinacea laevigata) 5.

No other nuisance species controls are proposed at this time. Inspections for beaver and other potential nuisance species will occur throughout the course of the monitoring period. Appropriate actions may be taken to ameliorate any negative impacts regarding vegetation development and/or water management on an as -needed basis. The presences of nuisance species will be monitored over the course of the monitoring period.

Mitigation Plan (Project No. 100058) page 36 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 9.1 Success Criteria Monitoring and success criteria for stream restoration should relate to project goals and objectives identified from on -site NC SAM and NC WAM data collection. From a mitigation perspective, several of the goals and objectives are assumed to be functionally elevated by restoration activities without direct measurement. Other goals and objectives will be considered successful upon achieving success criteria. The following summarizes Site success criteria. Table 17. Success Criteria Streams • All streams must maintain an Ordinary High -Water Mark (OHWM), per RGL 05-05. • Bank height ratio (BHR) cannot exceed 1.2 at any measured cross-section over the monitoring period. • BHR at any measured riffle cross-section should not change by more than 10% from baseline condition over monitoring period. • A minimum of 30-days continuous surface flow for intermittent streams. • The stream project shall remain stable and all other performance standards shall be met through four separate bankfull events, occurring in separate years, during the monitoring ears 1-7. Wetland Hydrology • Saturation or inundation within the upper 12 inches of the soil surface for, at a minimum, 10 percent of the growing season, during average climatic conditions. Note: Growing season length will be confirmed with a continuous recording temperature gauge that will measure from February to April each monitoring year. Vegetation • Within planted portions of the Site, a minimum of 320 stems per acre must be present at year 3; a minimum of 260 stems per acre must be present at year 5; and a minimum of 210 stems per acre must be present at year 7. • Trees must average 7 feet in height at year 5, and 10 feet in height at year 7 in each plot. • Planted and volunteer stems are counted, provided they are included in the approved planting list for the site; natural recruits not on the planting list may be considered by the IRT on a case -by -case basis. Note: BHR will be calculated using procedures outlined in the latest approved guidance from NCDMS. 9.2 Contingency In the event that stream success criteria are not fulfilled, a mechanism for contingency will be implemented. 9.2.1 Stream Contingency Stream contingency may include, but may not be limited to 1) structure repair and/or installation; 2) repair of dimension, pattern, and/or profile variables; and 3) bank stabilization. The method of contingency is expected to be dependent upon stream variables that are not in compliance with success criteria. Primary concerns, which may jeopardize stream success, include 1) structure failure, 2) headcut migration through the Site, and/or 3) bank erosion. Structure Failure In the event that structures are compromised the affected structure will be repaired, maintained, or replaced. Once the structure is repaired or replaced, it must function to stabilize adjacent stream banks and/or maintain grade control within the channel. Structures which remain intact, but exhibit flow around, beneath, or through the header/footer will be repaired by excavating a trench on the upstream side of the structure and reinstalling filter fabric in front of the pilings. Structures which have been compromised, resulting in shifting or collapse of a header/footer, will be removed and replaced with a structure suitable for Site flows. Mitigation Plan (Project No. 100058) page 37 Slingshot Creek Stream and Wetland Restoration Site Restoration Systems, LLC Rockingham County, North Carolina November 2019 Headcut Migration Through the Site In the event that a headcut occurs within the Site (identified visually or through measurements [i.e. bank -height ratios exceeding 1.4]), provisions for impeding headcut migration and repairing damage caused by the headcut will be implemented. Headcut migration may be impeded through the installation of in -stream grade control structures (rip -rap sill and/or log cross -vane weir) and/or restoring stream geometry variables until channel stability is achieved. Channel repairs to stream geometry may include channel backfill with coarse material and stabilizing the material with erosion control matting, vegetative transplants, and/or willow stakes. Bank Erosion In the event that severe bank erosion occurs within the Site, resulting in incision, lateral instability, and/or elevated width -to -depth ratios locally or systemically, contingency measures to reduce bank erosion and width -to -depth ratio will be implemented. Bank erosion contingency measures may include the installation of log -vane weirs and/or other bank stabilization measures. If the resultant bank erosion induces shoot cutoffs or channel abandonment, a channel may be excavated to reduce shear stress to stable values. 9.2.2 Wetland Contingency Hydrological contingency will require consultation with hydrologists and regulatory agencies if wetland hydrology enhancement is not achieved. Floodplain surface modifications, including construction of ephemeral pools, represent a likely mechanism to increase the floodplain area in support of jurisdictional wetlands. Recommendations for contingency to establish wetland hydrology will be implemented and monitored until Hydrology Success Criteria are achieved. 9.2.3 Vegetation Contingency If vegetation success criteria are not achieved, supplemental planting may be performed with tree species approved by regulatory agencies. Supplemental planting will be performed as needed until achievement of vegetation success criteria. 9.3 Compatibility with Project Goals The following table outlines the compatibility of Site performance criteria described above to Site goals and objectives that will be utilized to evaluate if Site goals and objectives are achieved.

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. Funding will be supplied by the responsible party on a yearly basis until such time an endowment is established. The NCDEQ Stewardship Program is developing an endowment system within the non -reverting, interest -bearing Conservation Lands Conservation Fund Account. The use of funds from the Endowment Account will be governed by North Carolina General Statute GS 113A-232(d)(3). Interest gained by the endowment fund may be used for the purpose of stewardship, monitoring, stewardship administration, and land transaction costs, if applicable.

SAW-2018-01170 County: Rockingham U.S.G.S. Quad: NC -Reidsville NOTIFICATION OF JURISDICTIONAL DETERMINATION Property Owner: NCDEQ DMS Attn: Tim Baumgartner Address: 1619 Mail Service Center Raleigh, NC 27699-1619 Size (acres) —12 Nearest Town Reidsville Nearest Waterway UT to Troublesome Creek / Lake Hunt River Basin Cane Fear USGS HUC 03030002 Coordinates 36.333480 N,-79.715103 W Location description: The proiect area is located approximately 0.1 mile north of the northern terminus of Harbor Road, near Reidsville, Rockingham Countv, North Carolina. The Proiect Area is shown as the "Slingshot Creek Stream Restoration Site Easement" on the attached Figure 3, titled "Slingshot Creek Stream and Wetland Mitigation Site Potential Waters of the US." Indicate Which of the Following Apply: A. Preliminary Determination ® There appear to be waters including wetlands, on the above described project area, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters including wetlands, have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. The approximate boundaries of these waters are shown on the enclosed delineation map dated August 2018. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further instruction. ❑ There appear to be waters including wetlands, on the above described project area/property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the waters including wetlands, have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWA/RHA jurisdiction over all of the waters including wetlands, at the project area, which is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters including wetlands, on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B. Approved Determination ❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ There are waters including wetlands, on the above described project area/property subject to the permit requirements of Section 404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ We recommend you have the waters including wetlands, on your project area/property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. ❑ The waters including wetlands, on your project area/property have been delineated and the delineation has been verified by the Corps. The approximate boundaries of these waters are shown on the enclosed delineation map dated MAP DATE. If you wish to have the delineation surveyed, the Corps can review and verify the survey upon completion. Once verified, this survey will SAW-2018-01170 provide an accurate depiction of all areas subject to CWA and/or RHA jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years. ❑ The waters including wetlands, have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official identified below on SURVEY SIGNED DATE. Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ There are no waters of the U.S., to include wetlands, present on the above described project area/property which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. ❑ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA). You should contact the Division of Coastal Management in Morehead City, NC, at (252) 808-2808 to determine their requirements. Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit may constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material, construction or placement of structures, or work within navigable waters of the United States without a Department of the Army permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If you have any questions regarding this determination and/or the Corps regulatory program, please contact David Bailev at (919) 554-4884 X 30 or David.E.Bailev2C&usace. army.mil. C. Basis For Determination: See the Preliminary Jurisdictional Determination form dated 5/7/2019. D. Remarks: None. E. Attention USDA Program Participants This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the particular site identified in this request. The delineation/determination may not be valid for the wetland conservation provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation in USDA programs, you should request a certified wetland determination from the local office of the Natural Resources Conservation Service, prior to starting work.

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.

Version: May 2017 Page 3 Jurisdictional Determination Request F. JURISDICTIONAL DETERNIINATION (JD) TYPE (Select One) ❑✓ I am requesting that the Corps provide a preliminary 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.

(Axiom) federally protected species survey at the Slingshot Creek Mitigation site in Rockingham County. The approximately 12-acre site is located north of Highway 158, 2 miles west of Reidsville, NC. Smooth Coneflower Smooth coneflower (Echinacea laevigata) is typically found on calcareous, basic, or circumneutral soils within clearcuts, power line right-of-ways, roadsides, and open woodlands where there is abundant light and little herbaceous competition. Suitable habitat for smooth coneflower occurs within open areas of the site, field borders, woodland edges, and forested areas along stream channels. Systematic surveys performed within areas of suitable habitat were performed by Axiom biologists Allison Keith and Andrew Radecki on May 21, 2018, and identified no individuals. As of May 25, 2018, the NCNHP has no record of this species within 1.0 mile of the site. The proposed project will have No Effect on smooth coneflower. We appreciate the opportunity to assist with this project. If you have any questions about this information, please let us know.

(Axiom) is pleased to provide you with this summary letter of the results of a survey for federally protected species on an approximately 12-acre tract (hereafter referred to as the site) planned for Slingshot Creek Mitigation Site in Reidsville, NC (see attached map). The survey was conducted by three Axiom biologists, Kenan Jernigan, Ryan Gibbons, and Allison Keith, on May 28, 2015. Site Description The site is in the Piedmont physiographic region of the state in southeastern Rockingham County. The site contains dissected, irregular plains with moderate to steep slopes and low to moderate gradient streams. Land use at the site is characterized by livestock pastures where livestock have unrestricted access to the streams. The majority of the site is dominated by herbaceous vegetation with some scattered shrubs, although, a narrow riparian fringe has developed along the stream margins that contains opportunistic species as well as a few mature trees. Dominant herbaceous species include a multitude of grasses, common pokeweed (Phytolacca americana), oxeye daisy (Leucanthemum vulgare), grape (Muscadinia sp.), and Japanese honeysuckle (Lonicera japonica). The scattered shrubs include winged sumac (Rhus copallinum), sweetgum (Liquidambar styracifZua), redbud (Cercis canadensis) and flowering dogwood (Corpus florida). The riparian fringes support narrow forests dominated by a canopy of loblolly pine (Pious taeda), eastern red cedar (Juniperus virginiana), sweetgum (Liquidambar styracifZua), and a mix of oaks (Quercus sp.). Federally Protected Species The U.S. Fish and Wildlife Service (USFWS) has identified one species with ranges that extend into Rockingham County: Smooth coneflower (Echinacea laevigata). A brief description of the species' habitat requirements follows, along with the Biological Conclusion rendered based on survey results in the study area. Habitat requirements for this species are based on the current best available information from referenced literature and/or USFWS. Smooth coneflower USFWS optimal survey window: late May -October Habitat Description: Smooth coneflower, a perennial herb, is typically found in meadows, open woodlands, the ecotonal regions between meadows and woodlands, cedar barrens, dry limestone bluffs, clear cuts, and roadside and utility right-of-ways. In North Carolina, the species normally grows in magnesium- and calcium -rich soils associated with gabbro and diabase parent material, and typically occurs in Iredell, Misenheimer, and Picture soil series. It grows best where there is abundant sunlight, little competition in the herbaceous layer, and periodic disturbances (e.g., regular fire regime, well-timed mowing, and careful clearing) that prevents encroachment of shade producing woody shrubs and trees. On sites where woody succession is held in check, it is characterized by a number of species with prairie affinities. Biological Conclusion: No Effect. Suitable habitat for smooth coneflower occurs throughout the study area within utility line corridors, along woodland edges, and within residential yards. A review of NCNHP records, updated April 2015, indicates no known smooth coneflower occurrences within 1.0 mile of the study area. Axiom biologists visited the UNC Botanical Garden on May 28, 2015 and found their smooth coneflowers to be in bloom. Subsequently, systematic surveys were performed in all areas of suitable habitat on the same day and no individuals of this species were identified within the study area. I hope this summary is sufficient for your review. Should you have any questions, please do not hesitate to send me an email (j ernigangaxiomenvironmental.org) or give me a call (919-215-9465).

Hamilton NCNHDE-4944 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. A query of the NCNHP database, based on the project area mapped with your request, indicates that there are no records for rare species, important natural communities, natural areas, or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists and is included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the project area, if any, are also included in this report. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement, or Federally -listed species are documented near the project area.

The Slingshot Stream and Wetland Mitigation Site proposes the restoration and enhancement of approximately 3,827 linear feet of stream, and the enhancement and reestablishment of 1.65 acres of wetlands. Stream restoration activities will include restoring appropriate dimension, pattern, and profile with Priority 1 restoration, which will improve wetland hydrology. Stabilization structures will be installed, which will also provide habitat. Native riparian buffers will be established, and all reaches will have fencing for livestock exclusion. Enhancement activities will include cattle exclusion, installing bed structures to enhance pool habitat, invasive treatment, and establishing a native woody riparian buffer.

Biologists with NCWRC have reviewed the provided documents. Comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667e) and North Carolina General Statutes (G.S. 113-131 et seq.). The Slingshot Stream & Mitigation Site is located north of the terminus of Harbor Road near Reidsville, Rockingham County, North Carolina. The project occurs on approximately 12 acres of livestock fields and disturbed forests. The project will provide in -kind mitigation for unavoidable impacts to streams and wetlands within the Cape Fear River Basin (HUC 03030002). The project will restore portions of unnamed tributaries of Lake Hunt. The site occurs within the Water Supply Watershed of Troublesome Creek, which is classified as a Water Supply III and Nutrient Sensitive Water by the N.C. Division of Water Resources (NCDWR). The U.S. Fish and Wildlife Service lists the federally endangered smooth coneflower (Echinacea laevigata) as having the potential to occur if suitable habitat is present. We have no records of rare, threatened, or endangered species within or near the mitigation site, although the lack of records from the project area does not imply or confirm the absence of federal or state protected species. Based upon the information provided to NCWRC, it is unlikely that stream and wetland mitigation will adversely affect any federal or state -listed species. However, we recommend leaving snags and mature trees or if necessary, remove tees outside the maternity roosting season for bats (May 15 — August 15). We recommend that riparian buffers are as wide as possible, given site constraints and landowner needs. NCWRC generally recommends a woody buffer of 100 feet on perennial streams to maximize the Mailing Address: Habitat Conservation • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 Page 2 20 June 2018 Slingshot Mitigation Rockingham County benefits of buffers, including bank stability, stream shading, treatment of overland runoff, and wildlife habitat. Stream restoration projects often improve water quality and aquatic habitat. Establishing native, forested buffers in riparian areas will help protect water quality, improve aquatic and terrestrial habitats, and provide a travel corridor for wildlife species. Provided measures are taken to minimize erosion and sedimentation from construction/restoration activities, we do not anticipate the project to result in significant adverse impacts to aquatic and terrestrial wildlife resources. Thank you for the opportunity to review this proposed project. If I can be of additional assistance, please call (336) 290-0056 or email olivia.munzer&ncwildlife.org.

Review@ncdcr.gov Re: Slingshot Stream & Wetland Mitigation Site, Columbus County, NC Dear Renee, The purpose of this letter is to request written concurrence from the State Historic Preservation Office (SHPO)for the Shaw's Run Stream & Wetland Mitigation Site in Columbus County, a Full -Delivery project for the N.C. Davison of Mitigation Services. Please review and comment on any possible issues that might emerge with respect to SHPO from a potential stream restoration project depicted on the attached mapping. Project Name: Slingshot Stream & Wetland Mitigation Site Project Location: 222 Harbor Rd. Reidsville, NC Project Contact: JD Hamby, Restoration Systems LLC, 1101 Haynes St. Suite 211, Raleigh, NC 27604 Project Description: The project has been identified for the purpose of providing in -kind mitigation for unavoidable stream channel and wetland impacts. Permits from the NC DWR and USACE will be obtained to restore waters of the US. Soil and erosion control permits will also be obtained. The project encompasses 9 acres of drained hydric soils, and cleared riparian buffer area currently used for row crop production. Approximately 2200 linear feet of stream and 4.4 acres of riparian wetland will be restored. The term "cultural resources" refers to prehistoric or historic archaeological sites, structures, or artifact deposits over 50 years old. "Significant" cultural resources are those that are eligible or potentially eligible for inclusion in the National Register of Historic Places. Evaluations of site significance are made with reference to the eligibility criteria of the National Register (36 CFR 60) and in consultation with the North Carolina State Historic Preservation Office (SHPO). Field visits were conducted in January 2017 to conduct evaluations for presence of structures or features that may be eligible for the National Register of Historic Places. No structures were identified within the Site boundaries that may be eligible for the National Register. In addition to field reviews for historically relevant structures, a records search was conducted at the SHPO office to determine if documented occurrences of historic structures or artifacts occur within, or adjacent to the Site. The SHPO records identify no features within the Site boundaries and seven features within a 1.0 mile radius of the Site, listed here: • RK1436 Carter House • RK1829 D.C. Smith Farm (DOE: 2005) • RK1589 Bartee Log House (DOE: 2005) • RK1430 Reid School • RK1437 House • RK1431 Alfred Reid House • RK1440 Pritchard -Tuttle House Typical SHPO coordination will occur prior to construction activities to determine if any significant cultural resources are present; however, no constraints are expected at this time. We thank you in advance for your timely response and cooperation. Please feel free to contact me with any questions that you may have concerning the extent of site disturbance associated with this project.

One of the earliest tasks to be performed by IRS is completion of an environmental screening and preparation/submittal of a Categorical Exclusion (CE) document. This document is specifically required by the Federal Highway Administration (FHWA) to ensure compliance with various federal environmental laws and regulations. DMS must demonstrate that its projects comply with federal mandates as a precondition to FHWA reimbursement of compensatory mitigation costs borne by the North Carolina Department of Transportation to offset its projects' unavoidable impacts to streams and wetlands. In order for the project to proceed, IRS is obligated to coordinate with the NRCS to complete Form AD-1006 in compliance with the Farmland Protection Policy Act on behalf of the FHWA. The purpose of this letter is to request your assistance in completion of the Form. Project Location & Description The Slingshot Creek Stream & Wetland Mitigation Site (hereafter referred to as the "Site"), is located approximately 2 miles west of Reidsville, NC, east of Lake Hunt, and north NC Highway 158. Site land use consists of disturbed forest, hay fields, and livestock pasture. All Site hydrology drains to unnamed tributaries to Lake Hunt. The proposed conservation easement area contains approximately 12 acres. The Site is located within Targeted Local Watershed (TLW) 03030002010010 and subbasin 03-06-01. According to the Cape Fear River Basinwide Water Quality Plan (NCDWQ 2005), all land uses and discharges of wastewater and stormwater in subbasin 03-06-01 potentially contribute nutrients to B. Everett Jordan Lake. B. Everett Jordan Lake provides low -flow augmentation, flood control, recreation, fish and wildlife habitat, and water supply. The lake is impaired for aquatic life due to excessive levels of chlorophyll a in violation of current standards in all segments of the reservoir. In addition, the Site has a supplemental water quality classification of Nutrient Sensitive Waters, which include areas with water quality problems associated with excessive plant growth resulting from nutrient enrichment. The proposed mitigation activities will reduce sediment and nutrient levels, and improve water quality within the Site and downstream watersheds. The project is located within the Troublesome Creek and Little Troublesome Creek Local Watershed Planning area (NCEEP 2004). Restoration Means & Methods Stream restoration efforts are designed to restore a stable stream that approximates hydrodynamics, stream geometry, and local microtopography relative to reference conditions. Restoration at the Site will be Priority I restoration; therefore, bankfull elevations will be raised to meet the adjacent valley floodplain elevation. Stream restoration is expected to entail 1) channel excavation, 2) channel stabilization, 3) channel diversion, and 4) channel backfill. The use of in -stream structures for grade control and habitat is essential for successful stream restoration. In -stream structures may be placed in the channel to elevate local water surface profiles in the channel, potentially flattening the water energy slope or gradient and directing stream energy into the center of the channel and away from banks. The structures will consist of log cross -vanes or logj-hook vanes; however, at the discretion of the Engineer, rock cross -vanes or rockj-hook vanes may be substituted if dictated by field conditions. In addition, the structures will placed in relatively straight reaches to provide secondary (perpendicular) flow cells during bankfull events. One drop structure is proposed at the Site outfal I; the drop structure may be constructed out of Terracell, or large cobble depending upon anticipated scour from the restored stream channels. The structure should be constructed to resist erosive forces associated with hydraulic drops proposed at the Site. Stream enhancement (level 1) will occur on reaches accessible by livestock. Stream dimension will be restored in these reaches, fencing will be erected to exclude livestock, and planting riparian buffers with native forest vegetation will occur where needed and will extend a minimum of 50 feet from the top of stream banks to facilitate stream recovery and prevent further degradation of the stream. Stream enhancement (level 11) will occur on reaches are characterized by channels with patches of mature riparian vegetation, good channel bed substrate, and little bank erosion. The reaches are accessible by livestock and will have fence erected to exclude livestock. Planting riparian buffers with native forest vegetation will occur where needed and will extend a minimum of 50 feet from the top of stream banks to facilitate stream recovery and prevent further degradation of the stream. Alternatives for wetland reestablishment are designed to restore a fully functioning wetland system, which will provide surface water storage, nutrient cycling, removal of imported elements and compounds, and will create a variety and abundance of wildlife habitat. Portions of the Site underlain by hydric soils have been impacted by stream degradation (incised and ditched channels), vegetative clearing, agriculture plowing, livestock compaction, herbicide application, and other land disturbances associated with land use management. Wetland reestablishment options should focus on the restoration of vegetative communities, restoration of stream corridors and historic groundwater tables, and the reestablishment of soil structure and microtopographic variations. In addition, the construction of (or provisions for) surface water storage depressions (ephemeral pools) will also add an important component to groundwater restoration activities. These activities will result in the reestablishment 0.96 acre and the enhancement of 0.69 acre of jurisdictional riparian riverine wetlands. Wetland enhancement will focus on the removal of livestock and restoration of vegetative communities resulting in the enhancement of 0.69 acre of riparian wetland Restoration of floodplain forest allows for development and expansion of characteristic species across the landscape. Ecotonal changes between community types contribute to diversity and provide secondary benefits, such as enhanced feeding and nesting opportunities for mammals, birds, amphibians, and other wildlife. Revegetating floodplains will provide overall system stability, shade, and wildlife habitat. In addition, viable riparian communities will improve system biogeochemical function byfiltering pollutants from overland and shallow subsurface flows and providing organic materials to adjacent stream channels. Variations in vegetative planting will occur based on topography and hydraulic condition of soils. Vegetative species composition will be based on RFEs, site -specific features, and community descriptions from Classification of the Natural Communities of North Carolina (Schafale and Weakley 1990). Community associations to be utilized include: 1) Piedmont/Low Mountain Alluvial Forest, 2) Dry-Mesic Oak -Hickory Forest and 3) Streamside Assemblage. Bare -root seedlings within the Piedmont Alluvial Forest and Dry-Mesic Oak -Hickory Forest will be planted at a density of approximately 680 stems per acre on 8-foot centers, and in the stream -side assemblage at a density of approximately 2720 stems per acre on 4-foot centers. Planting will be performed between November 15 and March 15 to allow plants to stabilize during the dormant period and set root during the spring season.

Threatened & Endangered Species Three federally protected species are listed as occurring in Rockingham County (USFWS 2015); the following table summarizes potential habitat and preliminary biological conclusions for each. Threatened and Endangered Species Species Habitat Potential Biological Habitat at Site Conclusion This freshwater mussel is limited to the James River drainage and the Dan/Mayo River drainage within the Roanoke River James spinymussel basin in Virginia, North Carolina, and West No No Effect (Pleurobema collina) Virginia. This species' range does not include the Site, which is located in the Upper Cape Fear River drainage. In North Carolina, this species is found in the Roanoke logperch Dan and Mayo rivers, as well as Big Beaver Island Creek. This species' range does not No No Effect (Percina rex) include the Site, which is located in the Upper Cape Fear River drainage. This species grows in calcareous, basic, or circumneutral soils on roadsides, clear cuts, Smooth coneflower and power line right-of-ways where there is (Echinacea laevigata) abundant light and little herbaceous Yes No Effect* competition. Fire -maintained woodlands also appear to provide potential habitat for the coneflower. *Detailed field surveys for this species were conducted during the optimum survey window. Smooth coneflower (Echinacea laevigata) is typically found on calcareous, basic, or circumneutral soils within clearcuts, power line right-of-ways, roadsides, and open woodlands where there is abundant light and little herbaceous competition. Suitable habitat for smooth coneflower occurs within open areas of the site, field borders, woodland edges, and forested areas along stream channels. Systematic surveys performed within areas of suitable habitat were performed by Axiom biologists Allison Keith and Andrew Radecki on May 21, 2018, and identified no individuals. As of May 25, 2018, the NCNHP has no record of this species within 1.0 mile of the site. The proposed project will have No Effect on smooth coneflower. Neither the James spinymussel nor the Roanoke logperch have ranges that extend into areas adjacent to or within the Site; therefore, this project will have no effect on these federally protected species. Suitable habitat for the smooth coneflower exists at the Site; therefore, surveys were conducted in May 2015, during the optimal survey window for this plant.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16U.S.C. 1531 etseq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. Section 7 of the Act requires that all federal agencies (or their designated non-federal representative), in consultation with the Service, insure that any action federally authorized, funded, or carried out by such agencies is not likely to jeopardize the continued existence of any federally -listed endangered or threatened species. A biological assessment or evaluation may be prepared to fulfill that requirement and in determining whether additional consultation with the Service is necessary. In addition to the federally -protected species list, information on the species' life histories and habitats and information on completing a biological assessment or 05/18/2018 Event Code: 04EN2000-2018-E-01667 evaluation and can be found on our web page at http://www.fws.gov/raleigh. Please check the web site often for updated information or changes If your project contains suitable habitat for any of the federally -listed species known to be present within the county where your project occurs, the proposed action has the potential to adversely affect those species. As such, we recommend that surveys be conducted to determine the species' presence or absence within the project area. The use of North Carolina Natural Heritage program data should not be substituted for actual field surveys. If you determine that the proposed action may affect (i.e., likely to adversely affect or not likely to adversely affect) a federally -protected species, you should notify this office with your determination, the results of your surveys, survey methodologies, and an analysis of the effects of the action on listed species, including consideration of direct, indirect, and cumulative effects, before conducting any activities that might affect the species. If you determine that the proposed action will have no effect (i.e., no beneficial or adverse, direct or indirect effect) on federally listed species, then you are not required to contact our office for concurrence (unless an Environmental Impact Statement is prepared). However, you should maintain a complete record of the assessment, including steps leading to your determination of effect, the qualified personnel conducting the assessment, habitat conditions, site photographs, and any other related articles. Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws. o� rg atoI3 birds/CurrentBirdIssues/Hazards/towers/ comtow.html. Not all Threatened and Endangered Species that occur in North Carolina are subject to section 7 consultation with the U.S Fish and Wildlife Service. Atlantic and shortnose sturgeon, sea turtles,when in the water, and certain marine mammals are under purview of the National Marine Fisheries Service. If your project occurs in marine, estuarine, or coastal river systems you should also contact the National Marine Fisheries Service, http://www.nmfs.noaa.gov/ We appreciate your concern for threatened and endangered species.

May 28, 2015 Worth Creech Restoration Systems 1101 Haynes St #211 Raleigh, NC 27604 Re: Federally Protected Species Assessment Results 15-007.05 Slingshot Creek, Reidsville, Rockingham County Dear Mr. Creech Axiom Environmental, Inc. (Axiom) is pleased to provide you with this summary letter of the results of a survey for federally protected species on an approximately 12-acre tract (hereafter referred to as the site) planned for Slingshot Creek Mitigation Site in Reidsville, NC (see attached map). The survey was conducted by three Axiom biologists, Kenan Jernigan, Ryan Gibbons, and Allison Keith, on May 28, 2015. Site Description The site is in the Piedmont physiographic region of the state in southeastern Rockingham County. The site contains dissected, irregular plains with moderate to steep slopes and low to moderate gradient streams. Land use at the site is characterized by livestock pastures where livestock have unrestricted access to the streams. The majority of the site is dominated by herbaceous vegetation with some scattered shrubs, although, a narrow riparian fringe has developed along the stream margins that contains opportunistic species as well as a few mature trees. Dominant herbaceous species include a multitude of grasses, common pokeweed (Phytolacca americana), oxeye daisy (Leucanthemum vulgare), grape (Muscadinia sp.), and Japanese honeysuckle (Lonicera japonica). The scattered shrubs include winged sumac (Rhus copallinum), sweetgum (Liquidambar styracifZua), redbud (Cercis canadensis) and flowering dogwood (Corpus florida). The riparian fringes support narrow forests dominated by a canopy of loblolly pine (Pious taeda), eastern red cedar (Juniperus virginiana), sweetgum (Liquidambar styracifZua), and a mix of oaks (Quercus sp.). Federally Protected Species The U.S. Fish and Wildlife Service (USFWS) has identified one species with ranges that extend into Rockingham County: Smooth coneflower (Echinacea laevigata). A brief description of the species' habitat requirements follows, along with the Biological Conclusion rendered based on survey results in the study area. Habitat requirements for this species are based on the current best available information from referenced literature and/or USFWS. Smooth coneflower USFWS optimal survey window: late May -October Habitat Description: Smooth coneflower, a perennial herb, is typically found in meadows, open woodlands, the ecotonal regions between meadows and woodlands, cedar barrens, dry limestone bluffs, clear cuts, and roadside and utility right-of-ways. In North Carolina, the species normally grows in magnesium- and calcium -rich soils associated with gabbro and diabase parent material, and typically occurs in Iredell, Misenheimer, and Picture soil series. It grows best where there is abundant sunlight, little competition in the herbaceous layer, and periodic disturbances (e.g., regular fire regime, well-timed mowing, and careful clearing) that prevents encroachment of shade producing woody shrubs and trees. On sites where woody succession is held in check, it is characterized by a number of species with prairie affinities. Biological Conclusion: No Effect. Suitable habitat for smooth coneflower occurs throughout the study area within utility line corridors, along woodland edges, and within residential yards. A review of NCNHP records, updated April 2015, indicates no known smooth coneflower occurrences within 1.0 mile of the study area. Axiom biologists visited the UNC Botanical Garden on May 28, 2015 and found their smooth coneflowers to be in bloom. Subsequently, systematic surveys were performed in all areas of suitable habitat on the same day and no individuals of this species were identified within the study area. I hope this summary is sufficient for your review. Should you have any questions, please do not hesitate to send me an email (j ernigangaxiomenvironmental.org) or give me a call (919-215-9465).

Hamilton NCNHDE-4944 The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. A query of the NCNHP database, based on the project area mapped with your request, indicates that there are no records for rare species, important natural communities, natural areas, or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists and is included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the project area, if any, are also included in this report. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement, or Federally -listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodney.butler(d).ncdcr.gov or 919.707.8603.

NCDMS Full Delivery Conservation Easement Template adopted 5 May 2017 Page 5 of 11 III. GRANTEE RESERVED USES A. Right of Access, Construction, and Inspection. The Grantee, its employees and agents, successors and assigns, receive a perpetual Right of Access to the Conservation Easement Area over the Property at reasonable times to undertake any activities on the property to restore, construct, manage, maintain, enhance, protect, and monitor the stream, wetland and any other riparian resources in the Conservation Easement Area, in accordance with restoration activities or a long-term management plan. Unless otherwise specifically set forth in this Conservation Easement, the rights granted herein do not include or establish for the public any access rights. B. Restoration Activities. These activities include planting of trees, shrubs and herbaceous vegetation, installation of monitoring wells, utilization of heavy equipment to grade, fill, and prepare the soil, modification of the hydrology of the site, and installation of natural and manmade materials as needed to direct in -stream, above ground, and subterraneous water flow. C. Signs. The Grantee, its employees and agents, successors or assigns, shall be permitted to place signs and witness posts on the Property to include any or all of the following: describe the project, prohibited activities within the Conservation Easement, or identify the project boundaries and the holder of the Conservation Easement. D. Fences. Conservation Easements are purchased to protect the investments by the State (Grantee) in natural resources. Livestock within conservations easements damages the investment and can result in reductions in natural resource value and mitigation credits which would cause financial harm to the State. Therefore, Landowners (Grantor) with livestock are required to restrict livestock access to the Conservation Easement area. Repeated failure to do so may result in the State (Grantee) repairing or installing livestock exclusion devices (fences) within the conservation area for the purpose of restricting livestock access. In such cases, the landowner (Grantor) must provide access to the State (Grantee) to make repairs. E. Crossing Area(s). The Grantee is not responsible for maintenance of crossing area(s), however, the Grantee, its employees and agents, successors or assigns, reserve the right to repair crossing area(s), at its sole discretion and to recover the cost of such repairs from the Grantor if such repairs are needed as a result of activities of the Grantor, his successors or assigns. IV. ENFORCEMENT AND REMEDIES A. Enforcement. To accomplish the purposes of this Conservation Easement, Grantee is allowed to prevent any activity within the Conservation Easement Area that is inconsistent with the purposes of this Conservation Easement and to require the restoration of such areas or features in the Conservation Easement Area that may have been damaged by such unauthorized activity or use. Upon any breach of the terms of this Conservation Easement by Grantor, the Grantee shall, except as provided below, notify the Grantor in writing of such breach and the Grantor shall have ninety (90) days after receipt of such notice to correct the damage caused by such breach.

Credit Release Schedules The standard release schedule for mitigation bank and ILF credits generated through stream and wetland mitigation projects has been modified to meet the new standards for the monitoring timeframes provided in this guidance document. For mitigation banks, the first credit release (15% of the bank's total stream restoration and/or enhancement credits) will occur upon establishment of the mitigation bank, and upon completion following criteria: 1) Execution of the MBI or UMBI by the Sponsor and the USACE 2) Approval of the final Mitigation Plan 28 3) The mitigation bank site must be secured 4) Delivery of the financial assurances described in the Mitigation Plan 5) Recordation of the long-term protection mechanism and title opinion acceptable to the USACE 6) Issuance of the 404 permit verification for construction of the site, if required. For mitigation sites that include preservation -only credits, 100% of the preservation credits will be released with the completion of the six criteria stated above. For ILF sites (including all NCDMS projects), no initial release of credits (Milestone 1) is provided because ILF programs utilized advance credits, so no initial release is necessary to help fund site construction. To account for this, the 15% credit release associated with the first milestone (bank establishment) is held until the second milestone, so that the total credits release at the second milestone is 30%. In order for NCDMS to receive the 30% release (shown in the schedules as Milestone 2), they must comply with the credit release requirements stated in Section IV(I)(3) of the approved NCDMS Instrument. The following conditions apply to the credit release schedules: A. A reserve of 10% of a site's total stream credits will be released after four bankfull events have occurred, in separate years, provided the channel is stable and all other performance standards are met. In the event that less than four bankfull events occur during the monitoring period, release of these reserve credits is at the discretion of the NCIRT. B. For mitigation banks, implementation of the approved Mitigation Plan must be initiated no later than the first full growing season after the date of the first credit transaction (credit sale). C. After the second milestone, the credit releases are scheduled to occur on an annual basis, assuming that the annual monitoring report has been provided to the USACE in accordance with Section IV (General Monitoring Requirements) of this document, and that the monitoring report demonstrates that interim performance standards are being met and that no other concerns have been identified on -site during the visual monitoring. All credit releases require written approval from the USACE. D. The credits associated with the final credit release milestone will be released only upon a determination by the USACE, in consultation with the NCIRT, of functional success as defined in the Mitigation Plan. 29 The schedules below list the updated credit release schedules for stream and wetland mitigation projects developed by bank and ILF sites in North Carolina: Credit Release Schedule and Milestones for Wetlands Credit Banks ILF/NCDMS Release Release Activity Interim Total Interim Total Milestone Release Released Release Released Site Establishment (includes all required criteria 1 15% 15% 0% 0% stated above) Completion of all initial physical and biological 2 improvements made pursuant to the Mitigation 15% 30% 30% 30% Plan Year 1 monitoring report demonstrates that 3 10% 40% 10% 40% interim performance standards have been met Year 2 monitoring report demonstrates that 4 ° 10 /° ° 50 /° ° 10 /° ° 50/° interim performance standards have been met Year 3 monitoring report demonstrates that 5 15% 65% 15% 65% interim performance standards have been met Year 4 monitoring report demonstrates that 6 interim performance standards have been met 5% 70% 5% 70% Year 5 monitoring report demonstrates that 7 ° 15 /° ° 85 /° ° 15 /° ° 85/° interim performance standards have been met Year 6 monitoring report demonstrates that 8 ° 5 /° ° 90 /° ° 5 /° ° 90/° interim performance standards have been met Year 7 monitoring report demonstrates that 9 10% 100% 10% 100% performance standards have been met *Please note that vegetation plot data may not be required with monitoring reports submitted during these monitoring years unless otherwise required by the Mitigation Plan or directed by the NCIRT.

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: Component/Feature Maintenance through project close-out Routine channel maintenance and repair activities may include securing of loose coir matting and supplemental installations of live stakes and other target Stream vegetation along the channel. Areas where stormwater and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head -cutting. 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 Vegetation plant species shall be controlled 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. Beaver and associated dams are to be removed as they colonize and until the Beaver project is closed. Site boundaries shall be identified in the field to ensure clear distinction between the mitigation site and adjacent properties. Boundaries may be identified by Site Boundary 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. Road crossings within the site may be maintained only as allowed by Road Crossing Conservation Easement or existing easement, deed restrictions, rights of way, or corridor agreements. Terracell Drop Routine maintenance and repair activities may include removal of debris and supplemental installation of live stakes and other target vegetation along the Structure channel. Undermining of the structure may require repair or replacement.
