Suggest using decimal degrees throughout the report; this is what IRT and others use to navigate to the site. • Review of the document indicates that decimal degrees were used on the Site location map, Table 4, directions to the site, NC WAM and SAM forms, and soil profiles. Suggest removing text that defines industry standards, such as definition of Rosgen classification system; it is not necessary and may lead to some confusion such as the statement that E type stream channels often occur in narrower valleys as stated in section 4.1.1.2. • Rosgen discussions of channel classification has been removed from Sections 4.1.1.2 and 4.1.2.2 Specific 3. Page 6, Valley confinement is indicated in Table 4 to be confined to moderately confined however the text describes the site as having wide, flat alluvial valleys with 100' floodplains. Revise or explain • Table 4 has been updated to read "Wide and flat alluvial valley". 4. Page 4, table 2: update Institution date to specific 4/18/2019 The institution date has been updated to 4/18/2019 5. Page 9, nutrient model: please include livestock type and number in the herd used to calculate nutrient and fecal loading. Total N and P have been calculated based on an area of pasture converted (5 acres) as stated in the document. Fecal coliform values have been based on two goats, a small donkey, and a horse. Text has been added to the document to clarify. 6. Page 10. 3.4 Project site Streams —Suggest mentioning re-establishing buffers and excluding livestock to this paragraph since these two activities contribute greatly to water quality benefits of the project. Text has been added to the paragraph to indicate the following "Site restoration activities including re-establishing buffers, excluding livestock, and restoring stream channels will....." 7. Page 11 Table 7.0-Given the size, classification, and parameters presented in Table 7.0 and text that indicates that comparison of small and large drainage area comparison will assist in site design parameters, please briefly explain how the Jordan Creek reference reach was used to develop proposed design parameters. • The comparison of various sized streams/watersheds is conductea using dimensionless ratios (example Lp-p/Wbkf, Rc/Wbkf). These dimensionless ratios allow comparison of Site channels and are presented in Table 131 (Appendix B). Table 7.0 does not ask for dimensionless ratios in the DMS templates. However, Table 131 provides a significant amount of information concerning these ratios and their subsequent design use. Text has been added to the Jordan Creek Reference Reach narrative (Section 4.1.2.1, pg. 16) to include the following. "The comparison of a small and large drainage area will assist in development of appropriate Site design parameters using dimensionless ratios (see Table B-1(Appendix B) Morphological Stream Characteristics. Dimensionless ratios allow for comparison of smaller and larger streams (see ratio variables presented in Table B-1)." 8. Page 12, 3.4.4 Valley Classification —There is a typo in the middle of the paragraph. Please change "slopwe" to "slope." • The typo has been fixed. 1101 Haynes St., Suite 211 • Raleigh, NC 27604 • www.restorationsystems.com • Ph 919.755.9490 • Fx 919.755.9492 9. On page 19 Table 12 — In the table, it listed UT1, UT3, and UT 6. However, there were only UT 1, UT 2, and UT 3 in the project. Please make necessary changes. • The table has been updated to include data for UT 1 upstream, UT 1 downstream, UT 2, and UT 3. 10. On page 20 Table 13 — In the table, it seems that both the Coastal Plain regional curve and the USGS regional model underestimated the bank full discharge comparing to the field indicate for McRea Land Company reference reach. However, the Coastal Plain regional curve over estimated while the USGS regional model was close to the bank full discharge comparing to the field indicator for Jordan Creek reference reach. Please explain which method was used to estimate the bank full discharge for the proposed condition. • i exi nas peen added to clarify the aesign bankfull cross sectional area. The text now reads as follows. "The designed onsite channel restoration area has been calculated using field indicators of bankfull at the reference reaches (average value) and bankfull indicators identified at the Site. This analysis indicates that design bankfull cross sectional area will equal 115 percent of the channel size indicated by Coastal Plain regional curves." 11. On page 23 Table 16 — In the table, it stated one of project goals was "minimize downstream flooding to the maximum extent possible". Please explain whether downstream flooding is an issue for the project watershed since majority of watershed is under the forest land use. Section 2 (Watershed Approach and Site Selection) outlines the Lumber River RBRP restoration goals for the CU include "buffering waterways and implementation of stormwater and agricultural BMPs". In addition, the upstream Site watershed is ditched dominated by agriculture fields that significantly increase downstream flooding. The DMS comment is valid due to the existence of the pond dam that historically would attenuate stormwater pulses. Yet the dam has been breached which during the breach caused extensive downstream flooding and no longer functions to stop excessive stormwater flows. 12. Page 24, Table 17. The biological conclusions shown on this table are ESA determinations. Rename this tab 'ESA determinations' or update the table with the biological conclusions listedon your table submitted to USF&W. i aole 17 has been renamed "Enaangered Species Hct ueierminations". 13. Page 26, Instream structures: Please clarify the intent to create perpendicular flow cells during bankfull events; is this perpendicular to stream banks? Vertical flow cells cause stream bank scour during turbulent flow. One purpose of in stream structures (vanes and cross vanes) is to change the flow cells perpendicular to the stream bed and banks which contribute to sediment transport and channel bar formation and maintenance. 14. Page 29, Table 18: UT 3 work proposed lists erase radius of curvatures along the channel. Please explain if this will be replaced by more stable sinuosity as opposed to removing all sinuosity. This was a typo. The text has been changed to read "ease" radius of curvatures. 15. Page 27, there is a piped channel crossing described here as inside the easement, but it is not shown on the restoration plan. Explain what this paragraph is describing or update to explain that these are outside of the easement. Text has been added to the document to indicate the crossings will be located upstream, and outside of the easement. 16. Page 27, Section 8.1.1. describes "not for credit" marsh treatment areas and indicates those are shown on Figure 6A and 613, but they are not visible on those pages or plan sheets. Please check that this paragraph is accurate to this project and shown on design. The marsh treatment area discussion has been removed from the document. There are no marsh treatment areas in this project. 17. Page 29, paragraph on wetland rehabilitation indicates that there are gauges installed in the rehabilitation areas (Appendix A and Figure 4). Please indicate when those gauges were installed and provide that data if Page 2 of 5 it is available. Also, please describe how hydrology will be improved in those areas to justify rehabilitation instead of enhancement. For example, the restoration plan (Figure 6) indicates that those areas of rehabilitation where UT2, UT3, and UT1 come together show that the channel depth will be decreased by approximately 1 foot, which should be mentioned in the text for the hydrologic and vegetative functional improvement. • Text has been added to the document including the following statements. - "These areas had preconstruction groundwater gauges installed in late May 2020." - "Groundwater gauge data will be included in as -built and annual monitoring reports for comparison to preconstruction gauge data." • At this time groundwater gauge data has not been collected or processed for inclusion into the detailed restoration plan. 18. The project credits table uses the terms, re-establishment, rehabilitation, and enhancement for wetlands. Section 8.3 page 29 is not clear on the plan for these three mitigation types, the text indicates that wetland restoration will occur through the creation of ephemeral pools and indicates that wetland rehabilitation will result in extended hydroperiod; there is no description of how wetland enhancement is to occur. Please update this section for more specificity and explanation. This section has been updated to break out each of the wetland mitigation types. A paragraph for wetland enhancement has been added to the document. Please note that ephemeral pools may be a part of the wetland reestablishment strategy; however, the strategy also lists the following activities. "Wetland reestablishment options will focus on the restoration of vegetative communities, restoration of stream corridors and historic groundwater tables, as well as the reestablishment of soil structure and microtopographic variations." 19. Page 32, Monitoring. It is likely that the IRT will require a flow gauge on UT2 because this is a pond removal and based on field conversations/discussions. Suggest addition of flow gauge for this reach in this section. UT 2 is characterized by a 263-acre drainage area and is considered a perennial stream. During the multiple IRT walkthrough visits of the Site, the flow regime of this tributary was not questioned. We will defer to IRT recommendations concerning monitoring of the flow regime; however, perennial streams typically do not require flow monitoring gauges. 20. Page 33, Table 21. Monitoring Summary. Continuous State Recorders are required for any reaches where Priority I restoration has occurred, the table lists number/extent in this column as NA and lists visual evidence, photo documentation and or rain data below this; that will not meet the 2016 requirements. This table also uses the term wetland restoration, please verify that this is intended to include both re- establishment and rehabilitation. Please include the source of the growing season and note that if soil temperature is used to validate a non- standard season; both temperature and bud burst /senescence will be necessary to document beginning and end of the season. Table 21, stream hydrology refers to flow gauges that monitor consecutive days of stream flow. As all the channels are perennial, there are no continuous monitoring flow gauges proposed at the Site. Bankfull event monitoring gauges (crest gauges) have been included in the Site and are included in Table 21. We have three crest gauges proposed for the Site located on UT 1 upstream, UT1 Downstream, and UT 2. • Text has been added for the wetland growing season to include the following. "*Soil temperature will be monitored using a continuous recording soil probe located at the rain gauge. The growing season will be initiated once bud burst has been documented on two or more species (excluding red maple and sambucus) and suitable soil temperatures have been documented with the soil probe. The earlies growing season initiation date will be March 1, assuming other growing season criteria has been met." 21. Page 33-34, Table 21 indicates 13 groundwater gauges, but there are 15 gauges showing on the monitoring plan map (Figure 15). • The table has been updated to include 15 groundwater gauges. Page 3 of 5 Construction Plan Sheets 1. Include a construction sequence sheet in the plan sheets. A preliminary erosion control construction sequence in the plans (Sheet C8.05). 2. Ensure to label wetlands in the plan sheets as the approved JD. • Wetland labels have been updated. 3. Show locations of proposed constructed riffles. • As the Site is a sand bed stream, there are no constructed riffles proposed for the project. The Typical detail for constructed riffles has been removed from the plan set. 4. Include a planting plan in the plan sheets. • The planting plan has been added to the plan set. 5. Explain how ephemeral pools and marsh treatment areas will be constructed as they are not shown on the plan sheets. • There are no marsh treatment areas proposed at the Site; therefore, no detail has been included in the plan set. Ephemeral pools are to be include as a field adjustment in areas of wetland that may need additional hydrology, or in abandoned channel backfill areas. These areas are to be less than 1 foot in depth and are to be elliptical in shape. At this time, we have no areas of expected ephemeral pools and do not have a detail for the depressions. Digital Data 1. Provide the proposed monitoring features displayed in Fig. 10 (e.g. cross sections, veg plots, etc). Monitoring equipment have been included in the digital submittal data. 2. The provided stream features for UT3 Reach 2 and UT2 Reach 2 do not connect to UT1 Reach 3. Please provide continuous stream features that accurately represent the Mitigation Plan Footage reported in Table 1. • The features have been added to the digital data submittal. Appendices/Figures 1. Appendices/Figures: Add a figure that shows the RFE and the two reference stream sites in relation to this project. This is especially important since the text of the Mitigation Plan relies heavily on the description and analyses of these systems. Figure 1A has been added to the document that shows the location of the Site and the adjacent reference sites. 2. Appendix D. Update to insert the with Beecher signature or email on the PJD, mitigation plan may not be approved without this document. Mr. Gary Beecher from the USACE has provided us with emailed approval that is now included but we have not received the tear sheet. We will update the document once we receive his signature. 3. Appendix H, I, and J are missing. Update these for final draft submission. • These appendices will be added for the final document. 4. Appendix K. — Add Tugwell and Haupt a -mails response to the final site visit minutes (11/7/2019 and 11/8/2019 e-mails). • The requested emails have been added to the site visit minutes.

The Site is located approximately 4 miles northwest of Rowland and 2.5 miles southwest of Alfordsville along the southwest edge of Robeson County near the North Carolina and South Carolina border (Figures 1 and 2, Appendix A). 1.1 Directions to Site Directions to the Site from Raleigh, North Carolina. ➢ Follow 1-40 for 29 miles, ➢ Take exit 328A to merge onto 1-95 South, ➢ After 79 miles, take exit 2 toward Rowland and turn right onto NC-130 West, ➢ After 2.5 miles, turn left onto Ashpole Church Road, then right onto Persimmon Road, ➢ After 2 miles, turn left onto Kitchen Street, ➢ The Site is on the right after approximately 0.5 mile and can be accessed from Rhein Drive. o Site Latitude, Longitude 34.56399N,-79.34909W (WGS84) 1.2 USGS Hydrologic Unit Code and NCDWR River Basin Designation The Site is located within Targeted Local Watershed (TLW) 03040204048010 (North Carolina Division of Water Resources [NCDWR] subbasin number 03-07-55. The Site is not located in a Local Watershed Plan (LWP), Regional Watershed Plan (RWP), or Targeted Resource Area (TRA) [Figures 1 and 2, Appendix A]). Site hydrology drains to unnamed tributaries to Wilkinson Creek (Stream Index Number 14-34-11), which has been assigned a Best Usage Classification of C, Sw (NCDWR 2013). Wilkinson Creek is not listed on the NCDENR draft 2018 or final 2016 303(d) lists (NCDEQ 2018a, NCDEQ 2018b). 1.3 Physiography and Land Use The Site is in the Atlantic Southern Loam Plains portion of the Southeastern Plains ecoregion of North Carolina. Regional physiography is characterized by dissected, smooth and irregular plains; broad interstream divides; Carolina bays; and mostly gentle side slopes dissected by many small, low to moderate gradient sandy -bottomed streams (Griffith et al. 2002). Onsite elevations range from a high of 140 feet National Geodetic Vertical Datum (NGVD) at the upper reaches to a low of approximately 115 feet NGVD at the Site outfall (USGS Rowland, North Carolina 7.5-minute topographic quadrangle) (Figure 3, Appendix A). The Site provides water quality functions to watersheds ranging from approximately 0.41 square mile (263 acres) on UT2 to 1.53 square miles (977 acres) at the outfall (Figure 3, Appendix A). The watershed is dominated by agricultural land, forest, and sparse residential development. Impervious surfaces account for less than 2 percent of the upstream watershed land surface. Land use at the Site is characterized by a breached agriculture ponds, row crops, livestock pasture, and disturbed forest. The agriculture ponds were breached in August 2018 during hurricane Florence and were in the process of being repaired for irrigation purposes when the site was identified for mitigation. Row crops are currently soybeans, but other crops are rotated regularly. Livestock including horses, donkeys and goats graze fields along the northern and eastern boundaries of the breached agriculture pond and have unrestricted access to the streams. Mitigation Plan (Project No. 100115) page 1 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 1.4 Project Components and Structure The Site encompasses 24.4 acres of drained pond, disturbed forest, and livestock pasture along unnamed tributaries to Wilkinson Creek. In its current state, the Site includes 3941 linear feet of degraded stream channel (based on the approved PJD), 15.9 acre of degraded wetland, 5.4 acres of drained, or otherwise impacted hydric soil (Figure 4, Appendix A). Proposed Site restoration activities include the construction of meandering, E/C-type stream channel resulting in 2403 linear feet of stream restoration, 1494 linear feet of stream enhancement (Level 1), 235 linear feet of stream enhancement (Level 11), 5.32 acres of riparian wetland re-establishment, 2.73 acres of riparian wetland rehabilitation , and 12.34 acre of riparian wetland enhancement (Table 1) (Figures 6 and 6A-6D, 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. Currently, the proposed Site is characterized as a drained pond surrounded by disturbed forest and livestock pasture. A summary of existing Site characteristics in favor of proposed stream and wetland activities include the following. • Streams and wetlands are accessible to livestock • Streams and wetlands subject to ditching/dredging and incision • Streams and wetlands have been cleared of forest vegetation • Streams and wetlands were impounded • 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 Mitigation Plan (Project No. 100115) page 7 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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]). The Lumber River Basin Restoration Priorities 2008 (RBRP) report (NCEEP 2008) documents restoration goals developed for the Lumber River Basin. The RBRP report documents restoration goals for the 03040204 catalog unit include buffering waterways and implementation of stormwater and agricultural BMPs. 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/Objectives). 3 BASELINE AND EXISTING CONDITIONS 3.1 Soils and Land Form Soils that occur within the Site, according to the Web Soil Survey (USDA 2020) are described in Table 5. Table 5. Web Soil Survev Soils Manned within the Site Map Map Unit Name Unit (Classification) Hydric Status Description Symbol This series consists of well -drained soils found on Aycock very fine broad interstream divides and flats on marine AyA sandy loam Non-hydric terraces with 0-2 percent slopes. The parent material (Typic Paleudults) is loamy and silty marine deposits. Depth to the water table is 48-72 inches. Depth to restrictive features is more than 80 inches. This series consists of poorly drained soils found on Bibb soils floodplains with 0-2 percent slopes. The parent BB (Typic Hydric material is sandy and loamy alluvium. Depth to the Fluvaquents) water table is 0-12 inches. Depth to restrictive features is more than 80 inches. This series consists of well -drained soils found on Faceville fine sandy ridges on marine terraces with 2-6 percent slopes. FaB loam Non-hydric The parent material is clayey marine deposit. Depth (Typic Kandiudults) to the water table and depth to the restrictive features is more than 80 inches. This series consists of well -drained soils found on Wagram loamy broad interstream divides and ridges on marine WaB, sand Non hydric terraces with 0-10 percent slopes. The parent WaC (Arenic material is loamy marine deposits. Depth to the Kandiudults) water table is 60-80 inches. Depth to restrictive features is more than 80 inches. The Web Soil Survey (USDA 2020) indicates the Site is mapped as Bibb soils with Wagram soils on the Side slopes. The Web Soil Survey mapping depicts the Site as impounded; however, the impoundment was breached during past hurricanes. Floodplain portions of the Site were confirmed as Bibb soils with impacts from sediment deposition in the pond and liquification/sloughing along side -slopes of the historic impoundment. Seepage slopes encroach upon the Wagram soils which indicate that Bibb soils, or other Mitigation Plan (Project No. 100115) page 8 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 hydric unmapped soils extend up the valley walls. These soils have been present for some time, as evidenced by drain tile extending up to agriculture fields. Detailed soil profiles collected by a licensed soil scientist appear to confirm that Site soils are hydric in nature and are characterized by F3 (depleted matrix) hydric soil indicators. The F3 indicator includes soils with 60 percent or more chroma 2 or less within the upper 6 inches or starting within the upper 10 inches of the soil profile. 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 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 Table 6. Table 6. BEHI and NBS Modeling Summary Stream Reach Proposed Mitigation Treatment Predicted Sediment Contribution (tons/year) UT 1 Restoration and Enhancement (Level I and 11) 241.0 UT 2 Restoration and Enhancement (Level I and 11) 2.0 UT 3 Restoration and Enhancement (Level I and 11) 1.1 Total Sediment Contribution (tons/year) 244.0 Based on this analysis, mitigation of Site streams will reduce streambank erosion and subsequent pollution of receiving waters. 3.3 Nutrient Model Nutrient modeling was conducted using a method developed by North Carolina Division of Mitigation Services (NCDMS) (NCDMS 2016) to determine nutrient and fecal coliform reductions from exclusion of livestock from the buffer. The equation for nutrient reduction for this model includes the following: TN reduction (Ibs/yr) = 51.04 (Ibs/ac/yr) x Area (ac) TP reduction (Ibs/yr) = 4.23 (Ibs/ac/yr) x Area (ac) Mitigation Plan (Project No. 100115) page 9 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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 1011 (col/AU/day) x AU x 0.085 Where: Col - quantities of Fecal Coliform bacteria AU - animal unit (1000 Ibs of livestock) Results of the NCDMS analysis indicate approximately 5 acres of easement are grazed by livestock, which contribute 255.2 Ibs/yr of nitrogen, 21.2 Ibs/yr of phosphorus, and 0.1 x 1011 col of fecal coliform/day that will be reduced due to exclusion of livestock from the easement area. Fecal coliform values have been based on two goats, a small donkey, and a horse. 3.4 Project Site Streams Streams targeted for restoration include unnamed tributaries to Wilkinson Creek, which have been cleared, impounded, dredged and straightened, trampled by livestock, eroded vertically and laterally, and receive extensive sediment and nutrient inputs from agriculture activities. Approximately 38 percent of the existing stream channel has been degraded contributing to sediment export from the Site resulting from mechanical processes from ditching of streams, clearing of vegetation, and liquification from impoundment. In addition, streamside wetlands have been cleared and drained by channel downcutting, drain tile installation, 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 including re-establishing buffers, excluding livestock, and restoring stream channels 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). Stream geometry measurements under existing conditions are summarized in Table 7 (Essential Morphology Parameters) and presented in detail in Table B1 (Appendix B).

Existing Site reaches are classified as unstable F, Eg-, and Cg-type streams with variable sinuosity. Existing Site reaches are characterized by sand substrate. 3.4.3 Channel Evolution Site streams targeted for restoration have been cleared of forest vegetation, channelized, and impounded resulting primarily in channels classified as channelized (Class III), degraded (Class IV), and aggraded and widened (Class V) channels throughout the Site (Simon and Hupp 1986). 3.4.4 Valley Classification Site Streams are characterized by moderately sized, second order, wide and flat alluvial valley with approximately 100-foot floodplain valley width. Valley slopes are typical for the Coastal Plain region and range from 0.0036 to 0.0062. UT 3 has a short valley that is characterized by a slope of 0.0125; however, this is artificially elevated by a combination of short reach, an offsite dam, and sediment deposits on the breached pond margins. Valley slopes in UT 3 should not hinder proposed water surface slopes, which are expected to be 0.0039 upon completion of the project. 3.4.5 Discharge This hydrophysiographic region is characterized by moderate rainfall with precipitation averaging approximately 45.6 inches per year (USDA 1987). Drainage basin sizes range from 0.41-square mile on UT2, and 1.53 square miles at the Site outfall. The Site's discharge is dominated by a combination of upstream basin catchment, groundwater flow, and precipitation. Based on indicators of bankfull at reference reaches and on -Site, the designed channel will equal the channel size indicated by Coastal Plain regional curves (Sweet et al. 2003); this is discussed in Section 5.2 (Bankfull Verification). Based on bankfull studies, the bankfull discharge ranges from 4.5-12.1 cubic feet per second for UT2 and the Site outfall, respectively. 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). Ajurisdictional wetland delineation was completed and verbally approved by United States Army Corps of Engineers (USACE) representative Gary Beecher during a field meeting on June 9, 2020. At this time Mr. Beecher has not given us the tear sheet, but has provided email approval of the delineation, included with the PJD in Appendix D, and the package will be updated upon receipt from the USACE. Existing jurisdictional wetlands are depicted in light blue cross hatch and drained hydric soils are depicted in yellow on Figure 4 (Appendix A). 3.5.1 Groundwater Model For this study, the Boussinesq equation was utilized to predict groundwater impacts associated with stream incision within the middle reaches of UT 1 (Reach 3) and the lower reaches of UT 2 and 3. These reaches are currently incised to a depth of 2.0 to 2.8 feet based on measured cross sectional data. Proposed channel depths are expected to be approximately 0.7 to 1.2 feet. Mitigation Plan (Project No. 100115) page 12 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 The Boussinesq equation was applied to Site streams to predict the linear distance of groundwater drawdown that exceeds 1 foot for 12-percent of the growing season. The percentage of the growing season (12 percent) was selected based upon guidance from the Wilmington District Stream and Wetland Compensatory Mitigation Update (IRT 2016). Results from the Boussinesq equation predicted lateral effects; results of the Boussinesq equation are summarized in Table 8. Table 8.

These gauges will record groundwater depth for approximately 1 year prior to construction activities. Depth to water table was noted in each gauge boring hole and additional mapping within the reach was conducted to ascertain model accuracy. Field review and boring data indicates the model slightly overpredicts drainage effects, with a 2-foot channel draining approximately 50 feet in the farthest extent. Mapping of the drainage effect was updated and is depicted in Figure 6 (Appendix A). 3.5.2 Hydrological Characterization Construction activities are expected to reestablish approximately 5.32 acre of drained/impacted riparian hydric soils, rehabilitate 2.73 acres of riparian wetlands, and enhance 12.34 acre of cleared riparian wetlands. Areas of the Site targeted for riparian 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, ditches, and/or drain tile installation. Other areas of hydric soil impairment result from overburden from dam, road, or pond construction. 3.5.3 Soil Characterization Detailed soil mapping conducted by a North Carolina Licensed Soil Scientist (NCLSS) in late 2019 and early 2020 indicate that the Site is currently underlain by hydric soils of the Bibb series (Figure 4, Appendix A). Soils have been disturbed by impoundment, livestock grazing, vegetation clearing, and conversion to pastureland. Soils in the historic impoundment are characterized by sedimentation associated with valley wall liquification and sloughing, as well as from improper sediment transport capacity. Dense herbaceous vegetation is colonizing the historic pond bed and trapping the sediment on the floodplain. Areas upstream of the historic pond bed have been drained by ditching, drain tile installation, and channel incision. A portion of these soils have been effectively drained; however, seeps and springs (as well as Mitigation Plan (Project No. 100115) page 13 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 collapsed drain tile) pockmark the area and are expected to have hydrology enhanced by proposed activities. Hydric soils within the historic pond bed are experiencing a drainage effect along the newly formed flow path following the breach of the dam. These hydric soils have also been partially buried in some areas as the result of sediment, mostly coarse sand, dropping out as the stream entered the former pond. This is particularly evident along the margins and upper extents of the former pond where streams entered the former pond. The soils in the historic pond are mapped as the Bibb series; however extended inundation has caused a build-up of organic material resulting in a mineral subsoil with a mucky modifier. Likewise the surface horizon in some areas is sand rather than the normally associated sandy loam due to the lack of sediment transport and aggradation from the adjacent stream channel. Onsite hydric soils are grey to gley in color and are predominantly associated with the F3-Depleted Matrix hydric soil field indicator. Eight detailed soil profiles conducted by a NCLSS are as follows; the location of these profiles are representatives of soils throughout the project (Figure 4 Appendix A). Table 9.

In addition, dimension, pattern, and profile variables have not been altered or degraded, allowing for assistance with the proposed restoration reaches (Figure 5A-B, Appendix A). Mitigation Plan (Project No. 100115) page 14 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 4.1.1 McCrea Land Company Reference Reach 4.1.1.1 Watershed Characterization The McCrea Land Company Reference Site is located in western Robeson County within the same physiographic province and similar landscape position as the Site. The reference reach is approximately 5 miles north of the Site in a topographic crenulation flowing to a significantly larger stream (Heel Creek). Alterations, development, and impervious surfaces within the watershed are minimal. 4.1.1.2 Channel Classification Stream geometry and substrate data have been evaluated to classify the reference reach based on a classification utilizing fluvial geomorphic principles (Rosgen 1996a). This classification stratifies streams into comparable groups based on pattern, dimension, profile, and substrate characteristics. The reference reach is characterized as an E-type, moderately sinuous (1.13) channel with a sand -dominated substrate. Reference reaches that are characterized by E-type channels typically have a dense herbaceous understory that resists erosive forces associated with deep, sinuous channels. 4.1.1.3 Discharge The reference stream has an approximately 0.20-square mile watershed and a bankfull discharge of 4.3 cubic feet per second based on bankfull indicators. 4.1.1.4 Channel Morphology Stream cross -sections and profiles were measured along the reference stream (Figure 5A, Appendix A). The stream reach is transporting its sediment supply while maintaining stable dimension, pattern, and profile. Stream geometry measurements for the reference stream are summarized in the Morphological Stream Characteristics Table (Table 131). Dimension: Data collected at the reference reach indicates a bankfull cross -sectional area of 4.8 square feet, a bankfull width of 6.0 feet, a bankfull depth of 0.8 feet, and a width -to -depth ratio of 7.5. Regional curves predict that the stream should exhibit a bankfull cross -sectional area of approximately 2.8 square feet for the approximate 0.20-square mile watershed (Sweet and Geratz 2003), above the 4.8-square feet displayed by channel bankfull indicators identified in the field. For a more detailed discussion on bankfull verification see Section 3.5 (Bankfull Verification). The reference reach exhibits a bank -height ratio averaging 1.0. In addition, the width of the floodprone area is approximately 75 feet giving the channel an entrenchment ratio of 11.4 to 13.9, typical of a stable E-type channel. Pattern: In -field measurements of the reference reach have yielded an average sinuosity of 1.13 (thalweg distance/straight-line distance). Other channel pattern attributes include an average pool -to -pool spacing ratio (Lp_p/Wbkf) of 3.5, a meander wavelength ratio (L,n/Wbkf) of 5.9, and a radius of curvature ratio (Rc/Wbkf) of 1.1. These variables were measured within a stable, forested reach, which did not exhibit any indications of pattern instability such as shoot cutoffs, abandoned channels, or oxbows. Profile: Based on elevational profile surveys, the reference reach is characterized by a valley slope of 0.0087 (rise/run). Ratios of the reference reach riffle, run, pool, and glide slopes to average water surface slope are 0.30, 0.78, 0.30, and 0.03, respectively. Substrate: The channel is characterized by a channel substrate dominated by sand -sized particles. Mitigation Plan (Project No. 100115) page 15 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 4.1.2 Jordan Creek Reference Reach 4.1.2.1 Watershed Characterization Jordan Creek is located approximately 17 miles north of the Site, in Central Scotland County. This reference reach is located in the same physiographic province and landscape setting. However, the channel is significantly larger than Site tributaries. The comparison of a small and large drainage area will assist in development of appropriate Site design parameters using dimensionless ratios (see Table B-1 (Appendix B) Morphological Stream Characteristics. Dimensionless ratios allow for comparison of smaller and larger streams (see ratio variables presented in Table B-1). 4.1.2.2 Channel Classification The reference reach is characterized as an E-type, high sinuosity (1.60) channel with a sand -dominated substrate. 4.1.2.3 Discharge The reference stream has an approximately 16.9-square mile watershed and a bankfull discharge of 44.3 cubic feet per second based on bankfull indicators. 4.1.2.4 Channel Morphology Stream cross -sections and profiles were measured along the reference stream (Figure 513, Appendix A). The stream reach is transporting its sediment supply while maintaining stable dimension, pattern, and profile. Stream geometry measurements for the reference stream are summarized in the Morphological Stream Characteristics Table (Table B1, Appendix B). Dimension: Data collected at the reference reach indicates a bankfull cross -sectional area of 44.9 square feet, a bankfull width of 20.8 feet, a bankfull depth of 2.2 feet, and a width -to -depth ratio of 9.7. Regional curves predict that the stream should exhibit a bankfull cross -sectional area of approximately 76.4 square feet for the approximate 16.9-square mile watershed (Sweet and Geratz 2003), below the 44.9-square feet displayed by channel bankfull indicators identified in the field. Low bankfull cross sectional area may result from high bedload and low slope conditions for the Site; however, these conditions appear to be in equilibrium as the channel width -to -depth ratio is typical for the area. For a more detailed discussion on bankfull verification see Section 3.5 (Bankfull Verification). The reference reach exhibits a bank -height ratio of 1.0, which is representative of a stable E-type channel. In addition, the width of the floodprone area is approximately 250 feet giving the channel an entrenchment ratio of 11.6-12.4, typical of a stable E-type channel. Pattern: In -field measurements of the reference reach have yielded an average sinuosity of 1.60 (thalweg distance/straight-line distance). Other channel pattern attributes include an average pool -to -pool spacing ratio (Lp_p/Wbkf) of 4.3, a meander wavelength ratio (L,n/Wbkf) of 5.5, and a radius of curvature ratio (Rc/Wbkf) of 1.3. These variables were measured within a stable, forested reach, which did not exhibit any indications of pattern instability such as shoot cutoffs, abandoned channels, or oxbows. Profile: Based on elevational profile surveys, the reference reach is characterized by a valley slope of 0.0013 (rise/run). Ratios of the reference reach riffle, run, pool, and glide slopes to average water surface slope are 1.1, 0.8, 3.5, and 0, respectively. Substrate: The channel is characterized by a channel substrate dominated by sand -sized particles. Mitigation Plan (Project No. 100115) page 16 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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 RFEs for this project are located on the two reference reaches and the downstream floodplain of Wilkinson Creek. The RFEs support 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 10 will be used, in addition to other relevant species in appropriate Schafale and Weakley (1990) community descriptions. i ame iv. rcererence rorest tcosystem Cypress -Gum Swamp Coastal Plain Small Stream Swamp (Brownwater Subtvoe) (Brownwater Subtvoe) Nyssa aquatica Taxodium distichum Nyssa biflora Nyssa aquatica Taxodium distichum Quercus michauxii Salix nigra Quercus shumardii Populus herophylla Quercus pagoda Carya aquatica Quercus laurifolia Fraxinus caroliniana Quercus nigra Celtus laevigata Platanus ocidentalis Betula nigra Salix nigra Nyssa biflora Liriodendron tulipifera The cypress -gum swamp (brownwater subtype) vegetative community is proposed for the downstream areas adjoining the larger floodplain of Wilkinson Creek. These are the lowest and wettest portion of the floodplain. This vegetative community is slow to recover from disturbance and due to inundation and poor nutrients is typically characterized by slow growth of tree species. This community grades upstream to the Coastal Plain small stream swamp vegetative community, but the boundary is indistinct and arbitrary. The Site should be classified as a blackwater subtype; however, sediment washing from upstream agriculture operations makes the system function more typical of a brownwater subtype community. Significant overlap in these two communities should not pose a problem as species in both communities may be planted in the overlap. 4.3 Freshwater Marsh Some portions of the Site are expected to be dominated by an open, herbaceous vegetative community characteristic of a Coastal Plain semipermanent impoundment as described in Schafale and Weakley (1990). Overbank flooding appears to occur and may result in extended periods of open water and emergent vegetation. Species listed in Table 11 below will be included in permanent seeding mix for stabilization.

The amount of degradation or aggradation is a function of relative magnitude of these forces over time. The interaction of flow within the boundary of open channels is only imperfectly understood. Adequate analytical expressions describing this interaction have yet to be developed for conditions in natural channels. Thus, means of characterizing these processes rely heavily upon empirical formulas. Traditional approaches for characterizing stability can be placed in one of two categories: 1) maximum permissible velocity and 2) tractive force, or stream power and shear stress. The former is advantageous in that velocity can be measured directly. Shear stress and stream power cannot be measured directly and must be computed from various flow parameters. However, stream power and shear stress are generally better measures of fluid force on the channel boundary than velocity. Stream power and shear stress were estimated for 1) existing dredged and straightened reaches, 2) the reference reaches, and 3) proposed Site conditions. Important input values and output results (including stream power, shear stress, and per unit shear power and shear stress) are presented in Table 10. Average stream velocity and bankfull discharge values were calculated for the existing Site stream reaches, the reference reach, and proposed conditions. In order to maintain sediment transport functions of a stable stream system, the proposed channel should exhibit stream power and shear stress values so the channel is neither aggrading nor degrading. Results of the analysis indicate the proposed channel reaches are expected to maintain stream power as a function of width values of approximately 0.12-0.17 and shear stress values of approximately 0.11-0.16 (Table 12).

Jordan Creek reference reach values for stream power and shear stress are slightly lower due to flatter valley and water surface slopes resulting in slightly 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 elevated compared to proposed values. 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. 5.2 Bankfull Verification Discharge estimates for the Site utilize an assumed definition of "bankfull" and the return interval associated with that bankfull discharge. 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). Current research also estimates a bankfull discharge would be expected to occur approximately every 0.1 to 0.3 years (Geratz et al. 2003). This is much shorter than previous state and nationwide estimates in other ecoregions of approximately every 1.3 to 1.5 years (Rosgen 1996, Leopold 1994). The shortened recurrence interval may be attributed to precipitation inputs onto wide, nearly level land with a large surface storage capacity, an elevated water table, and slow flushing rates (Geratz et al. 2003) Based on available Coastal Plain regional curves, the predicted bankfull discharge for the McRae Land Company and Jordan Creek Reference Reaches is 2.5 and 75.4 cubic feet per second (cfs) for the reference reaches (Sweet and Geratz 2003). 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 Coastal Mitigation Plan (Project No. 100115) page 19 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 Plain 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 4.3 and 44.3 cfs, respectively for the for the McRae Land Company and Jordan Creek Reference Reaches, which is 59 and 170 percent of that predicted by the regional curves. The USGS regional regression equation for the Coastal Plain region indicates that bankfull discharge at a 0.1-0.3 year return interval averages approximately 2-5 and 40-90 cfs, respectively (USGS 2006); similar to that predicted by bankfull indicators. Based on the above analysis of methods to determine bankfull discharge, proposed conditions at the Site will be based on reference reaches. Indicators of bankfull were used at the reference reaches to compare the bankfull cross -sectional area to that predicted by the curves. The designed onsite channel restoration area has been calculated using field indicators of bankfull at the reference reaches (average value) and bankfull indicators identified at the Site. This analysis indicates that design bankfull cross sectional area will equal 115 percent of the channel size indicated by Coastal Plain regional curves. Table 13 summarizes all methods analyzed for estimating bankfull discharge. Table 13.

The Site is located within Targeted Local Watershed (TLW) 03040204048010 (Figure 2, Appendix A). The RBRP report documents restoration goals for the 03040204 cataloging unit include buffering waterways and implementation of stormwater and agricultural BMPs. 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 Mitigation Plan (Project No. 100115) page 20 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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 14 through 16 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. Table 14.

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, any Site conditions that have the potential to restrict the restoration design and implementation were documented during the field investigation. No known Site constraints, that may hinder proposed mitigation activities, were identified during field surveys. Potential constraints reviewed include the following. 7.1 Threatened & Endangered Species Four federally protected species is listed as occurring in Robeson County as of February 21, 2020 (USFWS 2018); the following table summarizes potential habitat and a preliminary biological conclusion.

In the central Piedmont, it occurs on clayey soils derived from mafic rocks. The plant is shade intolerant and, therefore, grows best where disturbance (e.g., mowing, clearing, grazing, periodic fire) maintains its open habitat. 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 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 in December 2018 and December 2019 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 SHPO 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 two state listed species (significantly rare) including the coppery emerald (Somatochlora georgiana) and the Mitigation Plan (Project No. 100115) page 25 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 phantom darter (Triacanthagyna trifida). No natural areas or managed areas are documented within a one -mile radius of the Site (Appendix C). 7.4 FEMA Inspection of the FEMA Flood Insurance Rate Map 3710828800J, Panel 8288, effective January 19, 2005, indicates that downstream of the dam at the Site outfall the floodplain of Wilkinson Creek is mapped as AE floodplain. As the dam historically may have inhibited floodwaters (and therefore the AE floodplain) from extending upstream into the Site, the current breach in the dam may result in the Zone AE floodplain extending into the Site. The Site is not mapped by FEMA as AE floodplain. Correspondence with the local floodplain administrator Dixon Ivey (attached in Appendix F) indicates that no action will be required by FEMA for the project. An EEP floodplain requirement checklist is also include in the Appendix F. 7.5 Utilities A powerline located parallel to the upper reaches of UT 1 is expected to be moved outside of the proposed conservation easement. This utility is not expected to hinder mitigation activities. No other utilities are located within the proposed conservation easement. 7.6 Air Transport Facilities No air transport facility is located within 5 miles of the Site. 8 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 impoundment, land clearing, livestock grazing, straightening and rerouting of channels, ditching within the floodplain, 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 1), 3) stream enhancement (Level 11), 4) wetland reestablishment, 5) wetland rehabilitation, 6) wetland enhancement, and 7) vegetation planting (Figures 6A-6D, Appendix A). 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 a combination of Priority I and II restoration. Bankfull elevations will be raised to meet the adjacent valley floodplain elevation as soon a tie in elevations may be achieved. Stream restoration is expected to entail 1) channel excavation, 2) channel stabilization, 3) channel diversion, and 4) channel backfill. In -stream Structures In -stream structures will be used for grade control, habitat, and to elevate local water surface profiles in the channel, 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 Mitigation Plan (Project No. 100115) page 26 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 dictated by field conditions. In addition, the structures will be placed in relatively straight reaches to provide secondary (perpendicular) flow cells during bankfull events. Piped Channel Crossing Landowner constraints will necessitate the installation of two piped channel crossings upstream, and outside of the easement boundary, to allow access to portions of the property isolated by stream restoration activities Figure 5 (Appendix A). The crossings have been blown out during flooding/dam breach or are currently perched and serve as a barrier to wildlife crossing. The crossings will be constructed with suitable sized pipes to allow for stormwater flows, with adjacent floodplain pipes to allow for overflow discharge onto the floodplain. Materials will include hydraulically stable rip -rap or suitable rock. The crossings will be large enough to handle anticipated vehicular traffic. Approach grades to the crossings 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. 8.1.2 Stream Enhancement (Level 1) Stream enhancement (level 1) will entail restoration of stream dimension, installation habitat and grade control structures, easement markers, and planting riparian buffers with native forest vegetation to facilitate stream recovery and prevent further degradation of the stream. 8.1.3 Stream Enhancement (Level 11) Stream enhancement (level 11) will entail installation of easement markers and planting riparian buffers with native forest vegetation to facilitate stream recovery and prevent further degradation of the stream. 8.2 Individual Reach Discussions Mitigation strategies proposed for each reach are presented in Table 18.

Wetland Enhancement Wetland enhancement includes areas of existing wetlands (based on the approved PJD) that have been cleared of forest vegetation, have been impounded, or are pasture for livestock grazing. These areas will be planted with native forest vegetation and will have livestock removed/fenced from the area. Planting and livestock removal will enhance 12.331 acres of existing wetland within the Site boundaries. Wetland Reestablishment Portions of the Site underlain by hydric soils have been impacted by stream dredging, drain tile installation, vegetative clearing, agriculture grazing, and other land disturbances associated with land use management. Wetland reestablishment options will focus on the restoration of vegetative communities, restoration of stream corridors and historic groundwater tables, as well as 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 of approximately 5.32 acres of jurisdictional riparian riverine wetlands. Wetland Rehabilitation Wetland Rehabilitation will occur in areas of the Site that are currently jurisdictional; however, are currently being affected by groundwater drawdown from ditches, drain tiles, and channel incision. These areas had preconstruction groundwater gauges installed in late May 2020. The location of groundwater gauges are depicted on Figure 4 (Appendix A). Wetland rehabilitation areas should show and improvement in hydrology including increased hydroperiod of the gauge during normal climactic conditions and/or increased stream connectivity from stream overbank flooding. A series of nested groundwater gauges have been installed in the pond bed (Figure 6C, Appendix A). These gauges have been installed at a distance of 10, 20, and 45 feet from the stream top of bank. Nested gauges are installed to show a groundwater drawdown from incised streams in the pond bed. Wetland rehabilitation activities will result in approximately 2.73 acres of improved jurisdiction riparian wetlands. Groundwater gauge data will be included in as -built and annual monitoring reports for comparison to preconstruction gauge data. Mitigation Plan (Project No. 100115) page 29 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 8.4 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. 8.5 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 Communities of North Carolina (Schafale and Weakley 1990) were used to develop the primary plant community associations that will be promoted during community restoration activities. 8.5.1 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 flow 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. Cypress -Gum Swamp (Brownwater Subtype) is the target community for the lowest portions of the Site with Coastal Plain Small Stream Swamp (Brownwater Subtype) targeted for portions of the Site adjacent. Significant overlap in species for each planting community allows for a broad fringe between the ecological zones. Table 19 depicts the total number of stems and species distribution within each vegetation association (Figure 9, 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. Due to floodplain soils being of the Bibb series, scattered openings dominated by herbs and shrubs are likely to develop overtime. These areas are each expected to be less than an acre in size and encompass less than 20% of the Site. The general location of the herbaceous dominated wetlands are depicted on Figure 9 (Appendix A). As the wetland matures, poorly drained soils will make conditions favorable species like those described in a Coastal Plain Semipermanent Impoundment to thrive.

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. Appropriate actions will be taken to ameliorate any negative impacts regarding vegetation development and/or water management on an as -needed basis. 9 MONITORING AND SUCCESS CRITERIA Monitoring will be conducted by Axiom Environmental, Inc based on the schedule in Table 20. A summary of monitoring is outlined in Table 21(Figure 10, Appendix A). Annual monitoring reports will be submitted to the NCDMS by Restoration Systems no later than December 31 of each monitoring year data is collected. Table 21.

Mitigation Plan (Project No. 100115) page 34 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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 23. 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. • BHR at any measure riffle cross-section should not change by more than 10% from baseline condition during any given monitoring period. • 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 years 1-7. Wetland Hydrology • Saturation or inundation within the upper 12 inches of the soil surface for, at a minimum, 12 percent of the growing season, during average climatic conditions. 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. 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 mayjeopardize 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. 100115) page 35 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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. Ronk Frnsinn 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. Beaver and other Invasive Species Indications of beaver establishment will be monitored throughout the 7-year monitoring period. If beaver are identified in the Site, the location of the dam will be depicted on CCPV mapping and the beaver will be trapped during the following fall/winter. Once beaver have been trapped, the dam will be removed. Removal of the dam is expected to occur by hand to minimized disturbance to the adjacent mitigation areas. When invasive species controls are required by the IRT, species such as multiflora rose (Rosa multiflora), Russian olive (Eleagnus angustifolium), Chinese privet (Ligustrum sinense), and tree of heaven (Ailanthus altissima) will be treated by cutting and directly treating the stump with Garlon 4A (or other similar materials) to minimize re -sprouting. Appropriate actions to ameliorate any negative impacts regarding vegetation development and/or water management will occur on an as -needed basis. Additional monitoring, or other contingency measures will be determined by consultation with the IRT. Road/Culvert Maintenance Observation of road crossings/culverts will occur during regular monitoring visits conducted at the Site. Culverts will be monitored primarily for blockage; however, if erosion is occurring it will also be noted. Roadbeds, culverts, and crossings will be monitored for the seven-year monitoring period to ensure that no additional sediment deposition is occurring within the Site. Once the seven-year monitoring period has expired, maintenance of the crossing will be the responsibility of the landowner. Development/Logging Topographic re-entrants discharging into the conservation easement typically are directed into marsh treatment areas that treat the initial stormwater pulse to capture sediment and nutrients from adjacent runoff. These areas will naturalize over time into small wetland depressions. If the property adjacent to the Site is developed or logged such that excessive sediment enters the Site, the marsh treatment area may be re -excavated to capture additional drainage effluent. Maintenance of the marsh treatment area is not expected to occur over an extended period of time; however, short term maintenance may occur until stabilization of the adjacent landscape features occurs. Mitigation Plan (Project No. 100115) page 36 Swamp Grape Stream and Wetland Restoration Site Restoration Systems, LLC Robeson County, North Carolina September 2020 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 Table 23 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.

JURISDICTIONAL DETERMINATION (JD) TYPE (Select One) ❑f 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"ion 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 detennined to be jurisdictional under the Clean Water Act and/or Rivers and Harbors Act. Approved .1Ds 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.

REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLY): ❑ Office (Desk) Determination. Date: ❑ Field Determination. Date(s): 1 1. The Corps of Engineers believes that there may be jurisdictional waters of the United States on the subject site, and the permit applicant or other affected party who requested this preliminary JD is hereby advised of his or her option to request and obtain an approved jurisdictional determination (JD) for that site. Nevertheless, the permit applicant or other person who requested this preliminary JD has declined to exercise the option to obtain an approved JD in this instance and at this time. 2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general permit verification requiring "pre -construction notification" (PCN), or requests verification for a non -reporting NWP or other general permit, and the permit applicant has not requested an approved JD for the activity, the permit applicant is hereby made aware of the following: (1) the permit applicant has elected to seek a permit authorization based on a preliminary JD, which does not make an official determination of jurisdictional waters; (2) that the applicant has the option to request an approved JD before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an approved JD could possibly result in less compensatory mitigation being required or different special conditions; (3) that the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) that the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) that undertaking any activity in reliance upon the subject permit authorization without requesting an approved JD constitutes the applicant's acceptance of the use of the preliminary JD, but that either form of JD will be processed as soon as is practicable; (6) accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a preliminary JD constitutes agreement that all wetlands and other water bodies on the site affected in any way by that activity are jurisdictional waters of the United States, and precludes any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an approved JD or a preliminary JD, that JD will be processed as soon as is practicable. Further, an approved JD, 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, and that in any administrative appeal, jurisdictional issues can be raised (see 33 C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary to make an official determination whether CWA jurisdiction exists over a site, or to provide an official delineation of jurisdictional waters on the site, the Corps will provide an approved JD to accomplish that result, as soon as is practicable. This preliminary JD finds that there "maybe" waters of the United States on the subject project site, and identifies all aquatic features on the site that could be affected by the proposed activity, based on the following information: 2 SUPPORTING DATA.

Bodenhammer; 18-002 Dear Phillip Perkinson: The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database, indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence, the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Rodney A. Butler at rodnev.butlerWncdcr.aov or 919-707-8603.

This [document] provides a summary of the results of an Axiom Environmental, Inc. (Axiom) federally protected species survey at the Swamp Grape Mitigation Site. The approximately 20.5-acre site is located east of N.C. Highway 501 in Robeson County, NC. *Red -cockaded Woodpecker Habitat for red -cockaded woodpecker typically occupies open, mature stands of southern pines, particularly longleaf pine, for foraging and nesting/roosting habitat. The red -cockaded woodpecker excavates cavities for nesting and roosting in living pine trees, aged 60 years or older, and which are contiguous with pine stands at least 30 years of age to provide foraging habitat. The site supports scattered pines greater than 30 years old and a few pines greater than 60 years old. These pines are located sparsely among a primarily hardwood forest, resulting in unsuitable nesting and foraging habitat for red -cockaded woodpeckers. In addition, an investigation of these pines on May 21, 2019, found no evidence of red -cockaded woodpecker nesting/roosting. A review of NCNHP records dated May 24, 2019 indicates no occurrences of this species within 1.0 mile of the site. **%A1nnr4 ctnrk Wood stork is primarily associated with freshwater and estuarine habitats that are used for nesting, roosting, and foraging. Wood storks do not breed in North Carolina, however, a few disperse to southeastern North Carolina following the breeding season. Because of their specialized feeding behavior, wood storks forage most effectively in shallow -water areas with highly concentrated prey. Ideal foraging conditions are characterized by water that is relatively calm, open, and having water depths between 5 and 15 inches. The western side of site supports a small open water area with wetlands occurring throughout the entire site. This is considered suitable habitat. An investigation of the site was conducted by Axiom biologists on May 21, 2019 and found no evidence of wood stork foraging or roosting. As of May 24, 2019, the NCNHP has no record of this species within 1.0 mile of the site. ***Michaux's Sumac Habitat for Michaux's sumac consists of rocky, open, upland woods on acidic or circumneutral, well - drained sands or sandy loam soils, particularly where disturbance (such as mowing, grazing, clearing, or periodic fire) maintains an open habitat. Suitable habitat for Michaux's sumac occurs within open areas of the site, residential yards, and the edge of agricultural fields and the remnant pond. Systematic surveys performed within areas of suitable habitat were performed by Axiom biologists on May 21, 2019, and identified no individuals. As of May 24, 2019, the NCNHP has no record of this species within 1.0 mile of the site. ex hSai k 4YYFJiYJft United States Department of the Interior AWMWT FISH AND WILDLIFE SERVICE Raleigh Ecological Services Field Office Post Office Box 33726 Raleigh, NC 27636-3726 Phone: (919) 856-4520 Fax: (919) 856-4556 In Reply Refer To: February 05, 2020 Consultation Code: 04EN2000-2019-SLI-0818 Event Code: 04EN2000-2020-E-01352 Project Name: Swamp Grape Subject: Updated list of threatened and endangered species that may occur in your proposed project location, and/or may be affected by your proposed project To Whom It May Concern: The species list generated pursuant to the information you provided identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. 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 (16 U.S.C. 1531 et seq.). 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 02/05/2020 Event Code: 04EN2000-2020-E-01352 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/CurrentBirdlssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratory birds/CurrentBirdlssues/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. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Swamp Grape, 18-002.10 Dear Allison Keith: The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide information about natural heritage resources for the project referenced above. Based on the project area mapped with your request, a query of the NCNHP database indicates that there are no records for rare species, important natural communities, natural areas, and/or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence, the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile radius of the project area, if any, are also included in this report. If a Federally -listed species is found within the project area or is indicated within a one -mile radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here: https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water Management Trust Fund easement, or Federally -listed species are documented near the project area.

Box 149 Hoffman, NC 28347 Re: Swamp Grape Stream and Wetland Mitigation Project, Robeson County, NC Dear Ms. Garrison: The purpose of this letter is to request concurrence from the North Carolina Wildlife Recourse Commission concerning a stream and wetland restoration project located in Robeson County for the N.C. Division of Mitigation Services. The project will restore stream channels and riparian wetlands in a drained lake bed and forested areas. Please review and comment on any possible issues that might emerge with respect to the Fish and Wildlife Coordination Act from the potential stream restoration project. Attached is a USGS base map with the projects 21.5 acre footprint identified. The Site is located approximately 4 miles northwest of Rowland and 2.5 miles southwest of Alfordsville along the southwest edge of Robeson County near the North Carolina and South Carolina border. Site land use consists of a breached agriculture pond, disturbed forest, horse pasture, and row crops. The pond was breached in August 2018 during hurricane Florence. All Site hydrology drains to warm water, unnamed tributaries to Wilkinson Creek. The Site is located in the Atlantic Southern Loam Plains portion of the Southeastern Plains ecoregion of North Carolina. Regional physiography is characterized by dissected, smooth and irregular plains; broad interstream divides; Carolina bays; and mostly gentle side slopes dissected by many small, low to moderate gradient sandy -bottomed streams (Griffith et al. 2002). Onsite elevations range from a high of 140 feet National Geodetic Vertical Datum (NGVD) at the upper reaches to a low of approximately 115 feet NGVD at the Site outfall (USGS Rowland, North Carolina 7.5-minute topographic quadrangle) The Site is proposed to include 3,701 feet of combined restored and enhanced stream channel along with 10.1 acres of reestablished and enhanced riparian wetlands. Site alterations include the cessation irrigation source for row crop production, removal of the earthen dam, restoration of wetlands, and planting native, woody vegetation within the entire 21.5 acre Site easement. Mitigation outlined in this report will result in net gains in hydrology, water quality, and habitat functions, and are designed to provide 3,061 Stream Mitigation Units and 10.0 Non -riparian Wetland Mitigation Units. We thank you in advance for your timely response and cooperation. Please feel free to contact the below referenced Project Manager with any questions that you may have concerning the extent of site disturbance associated with this project.

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: Swamp Grape Stream and Wetland Mitigation Project Project Location: Site Latitude, Longitude 34.335125,-79.205717 (WGS84) 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 —20 acres of drain hydric soils, formerly used as an irrigation. Several thousand feet of stream and several acres of wetlands 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 Spring 2019 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 no features within a one mile radius of the Site. 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 isto request your assistance in completion of the Form. Project Location & Description The Site is located approximately 4 miles northwest of Rowland and 2.5 miles southwest of Alfordsville along the southwest edge of Robeson County near the North Carolina and South Carolina border. Site land use consists of a breached agriculture pond, disturbed forest, horse pasture, and row crops. The pond was breached in August 2018 during hurricane Florence. All Site hydrology drains to warm water, unnamed tributaries to Wilkinson Creek. The Site is located in the Atlantic Southern Loam Plains portion of the Southeastern Plains ecoregion of North Carolina. Regional physiography is characterized by dissected, smooth and irregular plains; broad interstream divides; Carolina bays; and mostly gentle side slopes dissected by many small, low to moderate gradient sandy -bottomed streams (Griffith et al. 2002). Onsite elevations range from a high of 140 feet National Geodetic Vertical Datum (NGVD) at the upper reaches to a low of approximately 115 feet NGVD at the Site outfall (USGS Rowland, North Carolina 7.5-minute topographic quadrangle) 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 entail 1) notching the dam to dewater sediments; 2) removal of the dam to the elevation of the adjacent floodplain; 3) excavating sediment that is unsuitable for channel bank construction; 4) backfilling areas of sediment removed with soil suitable for channel construction (if necessary); 5) excavation of the design channel, 6) stabilization of the channel with coir matting, seed, and mulch; and 7) installation of structures. The dam was breached in the summer of 2018 during hurricane Florence; however, landowners are reconstructing the dam for irrigation purposes. Therefore, the dam will be notched and the pond bed will be seeded with temporary grasses to stabilize sediments remaining in the pond. Care will be taken during notching of the dam to drain the maximum amount of water, thereby allowing sediments to dewater. Once the pond has dewatered and sediments have stabilized, the dam will be removed with finished grades matching elevations of the valley and floodplain above and below the dam location. Material removed from the dam, if suitable, may be used as channel backfill for reaches of stream to be abandoned during Priority I stream restoration efforts. If additional backfill remains, the material will be stockpiled outside of the easement, or spread evenly across the adjacent property and seeded for stabilization. Erosion control measures, such as silt fence, seeding, and mulching will be implemented on all stockpiled or spread soil materials. A determination on sediment quantity and quality within the abandoned pond will be made concerning the ability to work within, or to stabilize the sediment for stream construction. If sediment is deemed unsuitable for channel construction, the sediment will be removed from the vicinity of the design channel and spread along the outer margins of the pond. Subsequently, suitable soil material will be placed in the location of the design channel such that design channel banks will be stabilized without liquefaction. The removal of unsuitable material, installation of suitable material, and excavation of the design channel may occur simultaneously to reduce impacts of machinery on the pond bed. Excavation of the design channel will occur in the pond bed similar to other reaches of restored stream, with stabilization using approved erosion control materials and techniques. Bare -root seedlings will be planted at a density of approximately 680 stems per acre on 8-foot centers. Plantingwill be performed between November 15 and March 15 to allow plants to stabilize during the dormant periodandset root during the spring season. Potential species planted within the Site may include the following.

The Site encompasses approximately 26.7 acres of breached agriculture pond, disturbed forest, horse pasture, and row crops along unnamed tributaries to Wilkinson Creek. Proposed activities at the Site include the restoration of perennial and stream channels, enhancement of perennial stream channel, and restoration/enhancement of riparian wetlands. Stream reaches are depicted on the attached figures and lengths/priority are as follows: Reach Length Priority UT 1 2966 Restoration and Enhancement Level I and II UT 2 826 Restoration and Enhancement Level I UT 3 149 Restoration and Enhancement Level I FEMA mapping was reviewed to determine if the project is located in a FEMA study area (DFIRM panel number 8288). Based on existing floodplain mapping, the lower reaches of the Site below the breached dam are in Special Flood Hazard Area. Flood elevations in the Special Flood Hazard Area are likely to be controlled by the discharge of Wilkinson Creek and are not expected to be altered by proj ect activities; however, we request guidance from your organization as to how to mover forward with the project. We thank you in advance for your timely response and cooperation. Please feel free to contact the below referenced NC DMS Project Manager with any questions that you may have concerning the extent of site disturbance associated with this project.

The performance bonds must be obtained from a company licensed in North Carolina as shown in the Federal Treasury Listing of Approved Sureties (Circular 570). The maximum allowable amount provided by a surety may not exceed the "underwriting limitation" for the surety as identified in the Federal Treasury Listing. Although this RFP is a request for mitigation and not construction, the performance bonds shall follow the prescribed wording provided in N.C.G.S. § 44A-33. The Offeror must provide two performance bonds. The first bond must be for 100% of the total value of the contract and must be in effect and submitted with the Task 3 deliverable (see Section 8. SCOPE OF WORK —Task 3) before NC DMS will authorize payment for that deliverable. The bond must remain in effect until the Offeror has received written notification from the NC DMS that the requirements of Task 6 (submittal of baseline monitoring report) have been met. After the successful completion of Task 6, the bond can be retired and a second bond must be substituted for the first. The second bond must be for 40% of the value of the contract, which covers the monitoring period. The Monitoring Phase Performance Bond can be reduced yearly concurrent with the payment schedule once the yearly deliverable is approved by NC DMS and credits are released by the IRT. 2) Letters of Credit- LOCs must be drawn from a reputable Bank identified by the FDIC as "Well Capitalized" or "Adequately Capitalized" and follow the submittal timing, contract amounts and schedules for reduction as those described above for the performance bonds. Evergreen or irrevocable Letters of Credit shall be required to provide a 120 day notice of cancellation, termination or non -renewal. 3) Casualty Insurance on underlying performance of Credits or Units of Restoration — Must follow the same submittal timing, contract amounts and reduction schedules as those described above in performance bonds. The insurance must contain the following information. a) The "NC DENR" must be named as the "Regulatory Body'. NC DENR shall have the sole right to place a claim against the policy. NC DENR shall have the sole right and obligation as the responsible "regulatory body' to approve any claim settlement. b) Initial insurance must be for a 10 year period. The process of evaluating these options is underway. Once obtained, IRS will provide digital and hard copies of the assurance of distribution to IRT members.

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 above the site may be maintained only as allowed by Road Crossing Conservation Easement or existing easement, deed restrictions, rights of way, or corridor agreements. Routine maintenance and repair activities may include removal of debris and Drop Structure supplemental installation of live stakes and other target vegetation along the channel. Undermining of the structure may require repair or replacement.

One thing I just wanted to note is that I don't believe the majority of the wetland within the old pond bed will be rehabilitation, and the minutes seem oriented toward demonstrating that these areas will be rehabilitation. There may be some areas where sufficient uplift can be justified, but overall I think the functions within the pond bed are already present, so planting may be the major source of uplift (meaning enhancement). Also, the last bullet about removal of the infrastructure, including pipe and dock, would not really be justification for significant uplift.

As you said, this will be dependent upon the PJD. Also, I agree with Todd that the wetlands in the pond bottom are mostly enhancement. Also, as Erin suggested at the end of the site visit it would be preferable to extend the wetlands to the wood -line upstream of UT2. This would rely on the landowner willing to move the crossing they wanted in this area.

Swamp Grape Stream & Wetland Mitigation Site IRT Site Visit: 10-29-2019 NC DMS Contract # 7869 RFP # 16-007705 Supplementary Site Visit Notes TO: NC DMS FROM: Restoration Systems DATE: November 6, 2019 RE: Swamp Grape Stream & Wetland Mitigation Site Visit, October 29t", 2019 On May 30t", 2019, Restoration Systems (RS) held a post -contract site visit for the Swamp Grape Mitigation Site (Site) with the North Carolina Inter -agency Review Team (IRT). A significant portion of the Site encompasses a breached agricultural pond. Failure of the pond's earthen impoundment occurred during Hurricane Florence in September of 2018. RS and its consultant Axiom Environmental (Axiom) assessed the Site leading up to the May visit as if the breached impoundment was restorable, and the agricultural pond could be re-established. Though evaluated for compensatory mitigation, IRT members raised concerns regarding the permitting of the pond in 1999. Todd Tugwell of the U.S. Army Corps (Corps) relayed the IRT's concerns to the local Corps representative, Mickey Sugg, who conducted an internal review of the property. Mr. Sugg determined the Corps did not permit the construction but concluded the Corps would take no action against the landowner given the property's current condition. Moreover, if the landowner wanted to reconstruct the earthen impoundment, a Section 404 Permit would be required for the entire footprint of the pond. With clarity regarding the historical permitting, RS re-evaluated the Site based on its current condition. RS presented on preliminary findings during the September 2019 state-wide IRT meeting, and IRT members requested a second site visit, which occurred on October 29t", 2019. The following notes are a summary of the October site visit. Attendees: USACE: - Todd Tugwell NC DWR: - Mac Haupt - Erin Davis Axiom Environmental: - Grant Lewis NC DMS: - Lindsay Crocker - Jeff Schaffer - Jeremiah Dow - Tim Baumgartner Restoration Systems: - JD Hamby - Alex Baldwin - Raymond Holz Site Visit Notes: - Under RFP 16-007705, DMS awarded RS' Option 2, consisting of 3,061 SMUs and 10 RWMUs within a 20.5-acre easement. Under the revised evaluation, the easement size increased to 25.25 acres. The revised acreage is within the total amount Proposed under Option 1 of RS technical proposal, which proposed a 26.7-acre easement. The expanded footprint is aimed at generating sufficient wetland mitigation credit to satisfy contract thresholds with DMS. - DMS noted that due to the nature of impacts, 75% of the contracted wetland credit must be derived from "R" credit type (Re-establishment, Rehabilitation, or Creation). Page 1 of 4 Stream Notes: - UT-1: - UT-2: - UT-3: Swamp Grape Stream & Wetland Mitigation Site IRT Site Visit: 10-29-2019 NC DMS Contract # 7869 RFP # 16-007705 The condition of the upper reach calls for more design and channel work than currently proposed. An E1 approach or even R would be more favorable than E2. The slope of the banks should be shallower, and the channel brought up to at least the elevation of the culvert. Todd wants to see the justification of the channel design at the lower end of the reach just above the confluence, with defined success criteria in the mitigation plan (this goes for all E1/E2 reaches). The channel banks will be rebuilt following the low point in the valley. Mac does not want to see parallel channels unless the topography would justify it. IRT agreed that removing the dam at the property line would benefit the reach. - Main Channel (below the confluence of tribs 1, 2, & 3) Todd and Mac had concerns as to the level of work to be done, and whether thatjustified E1 at a ratio of 1.5:1. E2 at a ratio of 2.5:1 might be more appropriate in some areas. The mitigation plan will match the proposed design to the needs of the stream rather than the needs of the crediting. Lots of trees, wood, cross -veins, etc. will be added in this reach to improve habitat. The entire dam will be removed to achieve floodplain access. The clay will be used throughout the site for ditch plugs, and for stream structures. Justification will be needed as to the design below the dam. It was agreed below the dam is within the broader floodplain of Wilkinson Creek, which may drive the appropriate approach within this area. An ordinary high-water mark and channel exist currently. Wetland Notes: - The wetland mitigation potential and crediting strategy were discussed at length. Several areas shown as enhancement may fall under the definition of Rehabilitation if functional improvements are justified, but at a lower ratio (2:1). These should be explored in the Mitigation Plan as applicable. - Erin encouraged us to include removing deep areas of legacy sediment within pond bed and downstream of breached dam for wetland Creation at a 3:1 ratio, especially in areas where non- hydric sandy sediments have deposited in order to promote tree growth. - Prior to the start of 2020 growing season it was agreed that wells should be placed in existing wetland pockets proposed for Rehabilitation to determine a baseline condition. Page 2 of 4 Swamp Grape Stream & Wetland Mitigation Site IRT Site Visit: 10-29-2019 NC DMS Contract # 7869 RFP # 16-007705 Mac voiced concern about the source of hydrology in the drained hydric soils above the furthest upstream ditch along UT-1. A majority of the drained area along UT-1 was highly manipulated soils with hydrological inputs from springs at the top of the slope directed into the existing ditch network. - It was agreed that the mitigation plan should include verbiage about "Marsh like areas" that will likely develop in the wetter areas throughout the site. The mitigation plan will include success criteria for these areas based on the percentage of the wetland area; a threshold percentage will be determined for these areas not to exceed. Erin indicated that management of monoculture of Juncus could be tied to rehabilitation credit success. - Todd stated that sandy sediment removal could only provide Re-establishment credit if Johnston or Bibb soils could be documented below, but overall he discouraged seeking Rehabilitation credit in those areas but would consider creation at a 3:1 ratio. - Re-establishment of wetlands in the dam footprint at a 1:1 ratio would need to be justified - Removal of the dock, irrigation pipe, and other remnant infrastructure should be incorporated areas as part of the project's wetland approach.

Based on aerials and absence of any record of Corps dealings on the property, I informed him that authorization from our office would be required to replace/repair the breach and re -impound the site. In regards to the existing berm and pre -Florence work in the stream & wetlands, it is outside our 5-year statute of limitation for unauthorized work so no enforcement action will be taken for that past work. Informing me that there was an old breached berm (impounded in the 30s), he confirmed that the pond was reconstructed —2000 at the advice of Robeson County Ag. Dept (think he may be referring to NRCS) when he purchased the property. With this said, we will likely send the Bodenhamer's a letter restating our permit requirements. Not sure what that does to the mitigation proposal, but I'll leave that up to the IRT. If you have any questions, call me.
