(Wildlands) has reviewed the Division of Mitigation Services (DMS) comments from the Draft Monitoring Year 3 report for the Henry Fork Mitigation Project. The following Wildlands responses to DMS's report comments are noted in italics lettering. DMS comment; Executive Summary - While the detail is provided in Section 1.2.5, given the significance of the two MY02 fall storm events (Hurricane Florence and Tropical Storm Michael) in this region, it would be helpful to note in the ES that the site was evaluated following these events and that the results are in the narrative. Wildlands response; The requested verbiage was included in the Executive Summary. DMS comment; Section 1.2.2 — It is noted that a geomorphically significant event is still pending. Does Wildlands feel that Hurricane Florence and Tropical Storm Michael were not geomorphically significant events? Wildlands response, Wildlands agrees that Hurricane Florence and Tropical Storm Michael exceeded the geomorphic significant discharge (Qgs) for the site. However, Qgs documentation following these storm events was not completed due to the timing of the storm events. Wildlands is optimistic that it will be feasible to document at least two Qgs events within the remainder of the five-year monitoring period. DMS comment; Section 1.3 — It is noted that the Site has partially met the stream hydrologic success criteria; please describe what the criteria are. Wildlands response, Section 1.3 has been updated to describe the stream success criteria that has been met. "Multiple bankfull events were documented on both Vile Creek and UT1; therefore, the Site has partially met the stream hydrological success criteria of two or more bankfull events occurring in separate years within the restoration and enhancement reaches."

Mint Street, # 104 • Charlotte, NC 28203 kt� WILDLANDS ENGINEERING DMS comment; It would be helpful to show the station numbers on the CCPVs so the reader can match the narrative with the maps. Wildlands response; Wildlands has updated the CCPV maps to include the longitudinal stationing. DMS comment; Visual Assessment tables — Localized areas of scour /erosion are noted in Section 1.2.5; however, the visual assessment tables on some of these reaches indicate 100% performance. In addition, the "Totals" section for 'Bank' does not seem to be summed accurately in some instances. Please reexamine the visual assessment tables and provide an up-to-date and accurate depiction of areas of scour/erosion, undercut banks, etc. and totals following the fall 2018 major storm events. Wildlands response; Wildlands has updated the CCPVs to remove the stream areas of concern that do not meet the mapping threshold. The visual assessment tables (5a -5e) were also updated to reflect an accurate depiction of scour/erosion performance. Section 1.2.5 was updated to clarify the areas are under the mapping threshold and correct station numbers. DMS comment; As Wildlands has done in the past, please include a response to the comment letter and how/where the comments were addressed. Please insert this letter directly behind the cover page in the final deliverables. The IRT has requested that we include this letter with the final deliverables. The response letter will need to be included with all future monitoring deliverables. Wildlands response, Wildlands has included this response letter as part of the final report deliverable to DMS and the IRT.

Mint Street, # 104 • Charlotte, NC 28203 EXECUTIVE SUMMARY Wildlands Engineering, Inc. (Wildlands) completed a full -delivery stream and wetland mitigation project at the Vile Creek Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DMS) to restore and enhance a total of 8,056 linear feet (LF) of perennial and intermittent stream and to restore 6.40 acres of riparian wetlands in Alleghany County, NC. The Site is expected to generate 5,053 stream mitigation units (SMUs), and 5.70 riparian wetland mitigation units (WMUs) for the New River Basin (Table 1). The Site is located approximately one mile east of the Town of Sparta, NC in the New River Basin; eight -digit Cataloging Unit (CU) 05050001 and the 14 -digit Hydrologic Unit Code (HUC) 05050001030020 (Figure 1). The Site streams consist of Vile Creek and five unnamed tributaries (UT) to Vile Creek including UT1, UT1b, UT1c, UT2, UT3, and a portion of the Little River (Figure 2). Vile Creek flows into the Little River near the downstream site boundary. The land adjacent to the streams and wetlands is primarily maintained cattle pasture and forest. The Site is within a Targeted Local Watershed (TLW) identified in the New River Basin Restoration Priority (RBRP) plan (NCDENR, 2009). The Site is also located within the planning area for the Little River & Brush Creek Local Watershed Plan (LWP). The LWP identified the following stressors to watershed function: deforested buffers that are heavily grazed, livestock access to the streams, heavily eroded stream banks, land -disturbing activities on steep slopes, non -point source pollution from the Town of Sparta and surrounding areas, and drained and deforested wetland areas (NCDENR, 2007). The project goals defined in the mitigation plan (Wildlands, 2016) were established with careful consideration of goals and objectives that were described in the RBRP and to meet DMS mitigation needs while maximizing the ecological and water quality uplift with the watershed. The project goals established in the mitigation plan focused on permanent protection for the site, re-establishing natural hydrology and vegetation, reducing water quality stressors, and enhancing terrestrial and aquatic habitat. The Site construction and as -built survey were completed in February 2017. Monitoring Year (MY) 2 assessments and site visits were completed between April and November 2018 to assess the conditions of the project. Overall, the Site has met the required stream, vegetation, and hydrology success criteria for MY2. All restored and enhanced streams are stable and functioning as designed. Following the fall storm events (Hurricane Florence and Tropical Storm Michael), site conditions were evaluated, and the results are discussed later. During MY2, two bankfull events occurred on Vile Creek Reach 2 and one bankfull event occurred on UT1 Reach 2. UT1 pebble count reflected coarser material in both reaches. The overall average stem density for the Site is 502 stems per acre and is therefore on track to meet the MY3 requirement of 320 stems per acre for trees and 160 plants per acres for shrubs. All ten gages in the wetland re-establishment and rehabilitation areas are meeting or exceeding hydrology success criteria Vile Creek Mitigation Site Monitoring Year 2 Annual Report— FINAL VILE CREEK MITIGATION SITE Monitoring Year 2 Annual Report TABLE OF CONTENTS Section 1: PROJECT OVERVIEW.......................................................................................................1-1 Figure 2 1.1 Project Goals and Objectives.....................................................................................................1-1 Project Components and Mitigation Credits 1.2 Monitoring Year 2 Data Assessment..........................................................................................1-2 Table 3 1.2.1 Stream Assessment............................................................................................................1-2 Project Information and Attributes 1.2.2 Stream Hydrology Assessment..........................................................................................1-2 1.2.3 Vegetative Assessment......................................................................................................1-2 1.2.4 Wetland Assessment..........................................................................................................1-3 1.2.5 Areas of Concern/Adaptive Management Plan.................................................................1-3 1.3 Monitoring Year 2 Summary......................................................................................................1-4 Section2: METHODOLOGY.............................................................................................................2-1 Section3: REFERENCES................................................................................................................... 3-1 APPENDICES Appendix 1 Figures and Tables Figure 1 Project Vicinity Map Figure 2 Project Component Map Table 1 Project Components and Mitigation Credits Table 2 Project Activity and Reporting History Table 3 Project Contact Table Table 4 Project Information and Attributes Appendix 2 Visual Assessment Data Figure 3.0-3.4 Integrated Current Condition Plan View Table 5a -d Visual Stream Morphology Stability Assessment Table Table 6 Vegetation Condition Assessment Table Stream Photographs Vegetation Photographs Bog Vegetation Photographs Appendix 3 Vegetation Plot Data Table 7 Vegetation Plot Criteria Attainment Table 8 CVS Vegetation Plot Metadata Table 9a -b Planted and Total Stems and Planted Herbaceous Cover (Bog Cells) Appendix 4 Morphological Summary Data and Plots Table 10a -b Baseline Stream Data Summary Table 11 Morphology and Hydraulic Summary (Dimensional Parameters — Cross Section) Table 12a -b Monitoring Data — Stream Reach Data Summary Cross -Section Plots Reachwide and Cross-section Pebble Count Plots Appendix 5 Hydrology Summary Data and Plots Table 13 Verification of Bankfull Events Table 14 Wetland Gage Attainment Summary Groundwater Gage Plots & Stream Gage Plots Monthly Rainfall Data Vile Creek Mitigation Site Monitoring Year 2 Annual Report— FINAL Section 1: PROJECT OVERVIEW The Site is located approximately one mile east of the Town Sparta in eastern Alleghany County, NC. The project is within the New River Basin; eight -digit CU 05050001 and the 14 -digit HUC 05050001030020 (Figure 1). Located in the Blue Ridge Belt of the Blue Ridge Province (USGS, 1998), the project watershed primarily includes managed herbaceous, mixed upland hardwoods, and other forested land. The drainage area for the project streams range from 0.01 square miles to 2.69 square miles. The project streams consist of Vile Creek and five unnamed tributaries (UT) to Vile Creek including UT1, UT1b, UT1c, UT2, UT3, and a portion of the Little River. Stream restoration reaches include Vile Creek (Reaches 1 and 2) and UT1 Reach 2, which together comprising 3,047 linear feet (LF) of perennial stream channel. Stream enhancements reaches include UT1 Reach 1, UT1b, UT1c, UT2, UT3, and a portion of Little River, totaling 5,009 LF. Wetland components include 3.02 acres of wetland rehabilitation and 3.38 acres of wetland re-establishment. Construction activities were completed by Land Mechanic Designs, Inc. in February 2017. Planting and seeding activities were completed by Bruton Natural Systems, Inc. in February 2017. The land required for construction, management, and stewardship of the mitigation project included portions of five parcels resulting in 25.04 acres of the conservation easement. The project is expected to generate 5,053 stream mitigation units (SMUs) and 5.70 riparian wetland mitigation units (WMUs). Annual monitoring will be conducted for seven years with close-out anticipated to commence in 2024 given the success criteria are met. 1.1 Project Goals and Objectives The Site is intended to provide numerous ecological benefits within the New River Basin. While many of these benefits are limited to the Vile Creek project area; others, such as pollutant removal, reduced sediment loading, and improved aquatic and terrestrial habitat, have farther -reaching effects. Expected improvements to water quality and ecological processes are outlined below as project goals and objectives. These project goals were established with careful consideration of goals and objectives that were described in the RBRP and to address stressors identified in the LWP. The following project specific goals established in the mitigation plan (Wildlands, 2016) include: • Reduce pollutant inputs to streams including fecal coliform, nitrogen, and phosphorous; • Reduce inputs of sediment into streams from eroding stream banks; • Return a network of streams to a stable form that is capable of supporting hydrologic, biologic, and water quality functions; • Improve aquatic communities in project streams and provide improved habitat for trout migrating from Little River into Vile Creek. Note: Presence of aquatic organisms and trout will not be tied to project success criteria; • Raise local groundwater elevations and allow for more frequent overbank flows to provide a source of hydration for floodplain wetlands. Reduce shear stress on channels during larger flow events; • Restore wetland hydrology, soils, and plant communities; • Improve and expand Southern Appalachian bog habitat to support bog species such as bog turtles. Note: Presence of bog turtles will not be tied to project success criteria; • Create and improve riparian and wetland habitats by planting native vegetation. Provide a canopy to shade streams and reduce thermal loadings. Create a source of woody inputs for Vile Creek Mitigation Site Monitoring Year 2 Annual Report— FINAL 1-1 streams. Reduce flood flow velocities on floodplain and improve long-term lateral stability of streams. Improve bog habitat by planting herbaceous wetland plants; and Ensure that development and agricultural uses that would damage the site or reduce the benefits of project are prevented. 1.2 Monitoring Year 2 Data Assessment Annual monitoring and quarterly site visits were conducted during MY2 to assess the condition of the project. The stream, vegetation, and hydrologic success criteria for the Site follows the approved success criteria presented in the Vile Creek Mitigation Plan (Wildlands, 2016). 1.2.1 Stream Assessment Morphological surveys for the MY2 were conducted in April 2018. All streams within the site appear stable with some areas exhibiting minor scour. In general, the cross-sections show little change in the bankfull area, maximum depth ratio, and width - to -depth ratio. All cross-sections fell within the parameters defined for channels of the appropriate stream type (Rosgen, 1994 & 1996). Cross-section two shows slight scouring downstream of a vane/log sill which has created a micro -habitat within the chunky riffle structure. During MY1, cross-section seven reflected an increase in the cross-sectional area; however, there was no change during MY2. Wildlands will continue to watch these cross-sections in upcoming monitoring years. Pebble counts in Vile Creek indicated little to no change in substrate material, while UT1 indicates coarser materials in the riffle features from MY2. Refer to Appendix 2 for the visual stability assessment table, Current Condition Plan View (CCPV) map, and reference photographs. Refer to Appendix 4 for the morphological data and plots. 1.2.2 Stream Hydrology Assessment At the end of the seven-year monitoring period, two or more bankfull events and geomorphically significant (60%+ of bankfull flow) events must have occurred in separate years within the restoration and enhancement reaches. During MY2, the Vile Creek Reach 2 stream gage documented two bankfull events and the UT1 stream gage documented one bankfull event; however, no geomorphically significant events were documented. With multiple bankfull events recorded during MY1 and MY2 on both Vile Creek Reach 2 and UT1; the success criteria have partially been met for the restoration streams. Although the two fall storms were geomorphical significant events, the documentation for the success criteria was not completed due to the monitoring schedule and the timing of the events. The geomorphical significant event will be documented within the remainder of the five year monitoring period. The Refer to Appendix 5 for hydrology summary data and plots. 1.2.3 Vegetative Assessment A total of 17 woody vegetation plots were established during the baseline monitoring within the project easement area. The woody vegetation plots were installed using a 100 square meter quadrant (10m x 10m or 5m x 20m). The final woody vegetative success criteria will be the survival of 210 planted stems per acre in the planted riparian and wetland corridor at the end of the required monitoring period (MY7). The interim measure of vegetative success for the Site will be the survival of at least 320 planted stems per acre at the end of the third monitoring year (MY3) and at least 260 stems per acre at the end of the fifth monitoring year (MY5). Planted trees must average 10 feet in height in each plot at the end of the seventh year of monitoring. The success criteria for shrubs will be 160 surviving plants per acre at year 3, 130 at year 5, and 105 at year 7. There are no height criteria for shrubs. In addition, eight Vile Creek Mitigation Site Monitoring Year 2 Annual Report— FINAL 1-2 herbaceous vegetation bog plots were installed using a 20 square meter (5m x 4m) quadrant. The bog plots are assessed by visually estimating the percent coverage within each plot and must have 80% coverage for success criteria. The MY2 vegetative survey was completed in September 2018. The 2018 vegetation monitoring resulted in an average stem density of 502 stems per acre, which is greater than the interim requirement of 320 stems/acre required at MY3. During MY2, 15 of the 17 plots individually met the success criteria and the average stem height for the Site is 2.3 feet. With approximately 93% herbaceous coverage, the bog cells have become well established since project construction. Refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables. 1.2.4 Wetland Assessment A total of ten groundwater hydrology gages (GWGs) were established during the baseline monitoring within the wetland rehabilitation, wetland re-establishment, and bog areas. A barotroll logger (to measure barometric pressure used in the calculations of groundwater levels with gage transducer data) and a rain gage were also installed on Site. All monitoring gages are downloaded on a quarterly basis and maintained as needed. The final performance standard for wetland hydrology will be a free groundwater surface within 12 inches of the ground surface for 14 consecutive days (8.5%) of the defined 169 -day growing season which is measured under typical precipitation conditions. The final performance standard for bog areas will be a free groundwater surface within 12 inches of the ground surface for 20 consecutive days (12%) of the growing season. All ten GWGs met the success criteria for MY2; however, GWGs 2, 3 and 7-9 decreased from MY1. The decrease in water level for GWGs 7-9 may have been affected by lowering the most downstream berm that was initially backing up 6-10 inches of water. The measured hydroperiod ranged from 8% to 100% of the growing season. Wildlands will continue monitoring the change. Refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology summary data and plots. 1.2.5 Areas of Concern/Adaptive Management Plan Following Hurricane Florene and Tropical Storm Michael in Fall 2018, areas of minor scour and erosion were observed along several meander bends including, but not limited to Vile Creek Reach 3 station 124+00, Vile Creek Reach 1 and UT1 confluence, UT1 Reach 1 station 211+50, and UT2 station 306+50. The bank erosion areas were mostly associated with Enhancement I and Enhancement II streams. The UT2 stream, which is an Enhancement 11, was observed with bed aggradation at stations 308+75, 310+00, and station 311+25. Aggradation has resulted in sheet flow onto the flood plain rather than a single channel at station 311+25. While these areas are under the mapping threshold, Wildlands will continue to monitor the areas of concern during future site visits. The were some areas that required some remedial action after the IRT and DMS MY1 site walk, which appear to be stable and functioning properly. Specifically, the middle bog area on the left floodplain along Vile Creek Reach 1 contained concentrated flow paths that conveyed water through the bog. To prevent a potential headcut, the flow was dispersed by placing three coir logs across the concentrated flow paths. This was intended to be a temporary measure to prevent erosion until the vegetation was established, which was noted to have improved throughout this area in MY2. Wildlands will continue to monitor in subsequent years. Invasive species including Japanese barberry (eerberis thunbergii), Oriental bittersweet (Celastrus orbiculatus), and multiflora rose (Rosa multiflora) are present within and around the Site. These species are not impacting survival rates of planted stems at this time; however, 17.2% of the easement contained invasive plants that warranted treatment to prevent any future impact. The treatment Vile Creek Mitigation Site Monitoring Year 2 Annual Report— FINAL 1-3 included cutting to the plants and applying glyphosate the stumps or stems. Refer to Appendix 2 for the vegetation condition assessment table and the CCPV map. Less than 1% of the easement contains a few areas of poor herbaceous cover that are located between GWGs 7 and 8, along the right bank of UT2 around station 306+00 and the left bank of Vile Creek Reach 3 located at the boulder toe between stations 125+00 —126+00. These areas will require additional seeding, fertilizing and live stakes around the Vile Creek Reach 3 section. As stated earlier, multiple areas of erosion and scour have occurred throughout the Site. Wildlands will continue to monitor these areas and take necessary action to stabilize the bank, if the bank erosion advances. 1.3 Monitoring Year 2 Summary The streams within the Site appear to be stable and functioning as designed. Multiple bankfull events were documented on both Vile Creek and UT1; therefore, the Site has partially met the stream hydrological success criteria of two or more bankfull events occurring in separate years within the restoration and enhancement reaches. The average planted stem density for the Site is 502 stems per acres and is on track to meeting the MY7 success criteria and 15 of the 17 individual vegetation plots meet the MY3 success criteria as noted in the CCPV. Vegetation plots 9 and 14 may warrant a supplemental planting next winter. All groundwater gage met the success criteria for MY2; however, a change was observed in the hydrology for multiple gages. Planned management and maintenance will continue to address any areas of concerns that should advance or arise. Summary information and data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Mitigation Plan documents available on DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Vile Creek Mitigation Site Monitoring Year 2 Annual Report— FINAL 1-4 Section 2: METHODOLOGY Geomorphic data were collected following the standards outlined in The Stream Channel Reference Site: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). All Integrated Current Condition Mapping was recorded using either a Trimble or Topcon handheld GPS with sub -meter accuracy and processed using Pathfinder and ArcGIS. Crest gages were installed in surveyed riffle cross sections and monitored quarterly. Hydrologic monitoring instrument installation and monitoring methods are in accordance with the United States Army Corps of Engineers (USACE, 2003) standards. Planted woody vegetation is being monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2006).

The subject project site is an environmental restoration site of` - the North Carolina Department of Environmental Quality (DEQ) Division of Mitigation Services (DMS) and is encompassed by a recorded conservation easement, but is bordered by land under private ownership. Accessing the site may require traversing areas near or along the easement boundary and therefore access by the general public is not permitted. Access by authorized personnel of state and federal agencies or their designees/contractors involved in the development, oversight,and stewardship of the restoration site is permitted within the terms and timeframes of their defined roles. Any intended site visitation or activity by any person outside of these previously sanctioned roles and activites requires prior coordination with DMS. Directions to Site: To reach the site from Raleigh, NC, take 1-40 West toward US70/Greensboro/Winston-Salem. Keep right at the fork to continue on 1-40 Business West/US-421 North. Take exit 6B for US -52 North/US-311 North/NC-8 North toward Mount Airy/Smith Reynolds/Airport. Merge onto US -311 North/US-52 North and continue to follow US -52 North. Continue on 1-74 West. Take exit 6 for NC -89 toward Mount Airy. At the end of the exit ramp, turn left onto NC -89 West. Travel 13.7 miles, turn left onto NC -18 South. Travel 14.4 miles, cross over Vile Creek. Napco Road will be on the right. Take the next left onto a gravel farm road to access the Site.

The reductions are greater in the as -built compared to the mitigation plan. The as -built credit reductions follows the updated 2016 USACE Wilmington District Stream and Wetland Compensatory Mitigation update. 3Stream mitigation credits and stationg noted above are based on the as -built stream centerline.
