DMS has completed the review of the Little Pine Creek II Draft MY02 Monitoring Report. Following are the review comments/questions: • The report overall is clear, accurate and error free, DMS appreciates EWS's efforts on the project and report. • Please add a footnote to Table 12 (bank full events) indicating that the multiple listed dates for 2021 (and represented by the some photo) were based on precipitation and stage recorder data were recorded over the specified time period. Footnote added. • If possible please include one photo each of the three scoured/eroded "areas of concern" on LPC (110+25, 120+75, and 121+50). DMS has observed these recently as well and will continue to assess them over time. Photos and descriptions added to Appendix B. • Vegetation — please indicate that DMS is currently under a 4-year contract to manage and treat the various small pockets of invasive vegetation. Text added. DIGITAL SUPPORT FILES Please include the random plot data across all years in the input template so that these data are included in the output Vegetation Performance Standards Summary Table. Random Plot data collected during MY1 was mistakenly collected using warranty plot methodology and is not compatible with entry into the DMS Veg Tool. Random Plot data will be retained within the input 37 Haywood Street, Suite 100 Asheville NC 28801 828.253.6856 www.equinoxenvironmental.com EQUINOX balance through proper planning table in future monitoring reports. The MY1 stem density table for random plots has been included in the digital support files. Before calculating the BHR, all points outside of the main channel (as defined by the low bank height) must be excluded from the cross -sectional area using Omit BKF. Otherwise, when the user adjusts the bankfull elevation to determine the elevation that achieves the MYO bankfull area, those areas outside of the main channel will be included. For example, XS11 should exclude point stations 0.00-18.38 and 25.02-42.1 before adjusting the bankfull stage to achieve a cross sectional area of 6.5. The resulting BHR would be 0.6. Please ensure this is done consistently for all cross sections. Data and BHR calculations checked for consistency and revised within the tables and figures. • Please report the current year's cross -sectional area rather than the MYO cross sectional area in cross section figures and Table 11a. Updated tables to reflect field identified BKF. Please submit two final hard copies, in addition to a flash drive or CD with a PDF of the report and all digital support files (addressing any comments) in the correct file structure. Please include a copy of your response letter, inserted inside the front cover of each hard copy report (and included in the final PDF). If you have any questions about these comments, please contact me at (828) 545-7057 or email me at harry.tsomides@ncdenr.gov before running any final copies."

Project Setting and Background The Site is located in eastern Alleghany County, NC, approximately eight miles east of the Town of Sparta, NC and approximately four miles south of the Virginia border. The Site is within the New River Basin; 14- digit Hydrologic Unit Code (HUC) 05050001030030 and located in the Blue Ridge Belt of the Blue Ridge Province (USGS, 1998), (Figure 1). The Site is located within a TLW in the New River RBRP plan (NCDENR, 2009), and is identified in the Little River and Brush Creek LWP Project Atlas (NCDENR, 2007). Numerous stressors were identified including heavily grazed buffers, livestock access to streams, eroded stream banks, land -disturbing activities on steep slopes, and storm water runoff. The LWP Project Atlas identified the Little Pine Creek 11 Stream and Wetland Restoration Project (LPC1-04, LPC1-W10) as a stream and wetland restoration opportunity with the potential to improve water quality, habitat, and hydrology within the Brush Creek watershed. Tables 1-4 in Appendix A present the project details. 1.2. Goals and Objectives The following goals are outlined in the Final Mitigation Plan, and include: • Restore riparian buffers • Exclude cattle • Stabilize eroding banks • Construct stream channels that are laterally and vertically stable • Improve stream habitat • Improve channel and floodplain connectivity • Permanently protect the project site from harmful uses The following project objectives are proposed for accomplishing the goals as outlined in the Final Mitigation Plan: • Plant native tree and understory species in the riparian zone. • Install fencing along the conservation easement and cattle pasture boundaries • Reconstruct stream channels with stable dimensions, add bank revetments and in -stream structures to protect restored/enhanced streams. • Construct stream channels that will maintain a stable pattern and profile considering the hydrologic and sediment inputs to the system, landscape setting and the watershed condition. • Install habitat features such as constructed riffles and brush toed into restored/enhanced streams, add woody materials to channel bed, and construct pools of varying depth. • Reconstruct stream channels with bankfull at or near the floodplain elevation and bank height ratios ranging from 1.0- 1.1. • Establish a conservation easement on the site. 1.3. Restoration Type and Approach The project includes six restoration reaches; three Priority 1 (P1) reaches on Little Pine Creek, one Priority 2 (P2) reach on Tributary A, one P1 reach on Tributary B, and one P1 reach on Tributary C. The preservation portion of the Site includes Tributaries D, E, and F. The wetland portion of the LPC II Site includes three wetland zones. Wetland 1 is a riparian, non-riverine wetland enhancement zone. Wetland 2A is a riparian, non-riverine wetland enhancement zone. Wetland 2B is preservation only. 1.4. Project Components and Success Criteria The LPC II Site is expected to provide 3,195 SMUs and 1.484 WMUs. The components and mitigation credits Project credits reflect those approved as part of the March 13, 2020 Little Pine Creek II -Project As - Built Update and Mitigation Plan Addendum (downward adjustment), Appendix F. Refer to the Project Assets Map (Figure 2) for the stream and wetland features and Table 1 and 4 for the project components, assets, and mitigation credit information for the LPC II Site (Appendix A). The initial credit release for LPC II was received on April 3, 2020 1.5. Project Performance 1.5.1 Vegetation Visual assessment of vegetation indicates that the herbaceous vegetation is well established throughout the project. MY2 stems/acre and ranged from 243 to 729 planted stems per acre. Eight species were documented within the vegetation monitoring plots. A supplemental planting of 1450, 18-24" bare root seedlings was conducted on February 9, 2021. Species planted included tulip poplar (Liriodendron tulipifera), swamp chestnut oak (Quercus michauxiij, river birch (Betula nigra), sycamore (Platanus occidentalis, and water oak (Quercus nigra). Monitoring of both permanent (n=8) and random vegetation plots (n = 4) was completed in October 2021. Summary tables and photographs associated with MY2 vegetation monitoring are located in Appendix B and Appendix C. MY2 monitoring data indicates that all but vegetation plot 6 were meeting the MY3 interim success criteria of 320 planted stems per acre (Table 7 and 8, Appendix C.) Three areas of low stem density were identified in MY2. The first area of concern is overbank scour located mid -reach at STA 112+00 has some vegetation reestablishment but was still considered a problem area in MY2. The second area was located adjacent to Veg Plot 7 and is an area of poor soil with limited ground cover establishment. The third area called out in MY2 is located at Station 124+50, the downstream boundary of the project and is an area of bank scour with sparse vegetation (Table 6 and CCPV, Appendix B). An area noted in MY1 between Cross -sections 3 and 5 continues to receive overbank deposition but impacts to existing planted stems seem to be less in MY2. Thus, this area was removed from the areas of concern. These areas will continue to be monitored in future site visits for further signs of instability. Vegetation problem areas continue to be restricted to the immediate floodplain of Little Pine Creek Some of the low stem density areas noted in MYO and MY1 are still present, particularly within the channel belt width on Reach 2A (Table 6 and CCPV, Appendix B). Areas of exotic vegetation are depicted within the CCPV (n=29). Multiflora rose (Rosa multiflora), Oriental bittersweet (Celastrus orbiculatus) and Japanese honeysuckle (Lonicera japonica) were the dominant observed species. Some pockets of cat tail (Typha latifolia) were identified in the wetter areas of the right descending floodplain. Invasive vegetation was identified in low density pockets throughout LPC Reach 1 and 2A. The most contiguous area of invasives noted within the CCPV contains a significant density of oriental bittersweet. The location and density of invasive vegetation will continue to be monitored in future site visits. DMS is currently under a 4-year contract to manage invasive vegetation within the site. 1.5.2 Geomorphology Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. Reaches 1 and portions of Reach 2A continue to experience overbank deposition (Cross Section figures, Tables 11a and b, Appendix D). The floodplain erosion noted in MY1 at the left descending bank of Cross-section 1 has filled in somewhat and appeared stable in MY2 (Cross-section graphics and photos, Appendix D). The transverse riffle near STA 101+50 identified in MY1 is still present but is not contributing any problems to the area. This area will continue to be monitored for any changes in stability. Geomorphic data for MY1 was collected during October 2021. Summary tables and cross-section data plots related to stream morphology are located in Appendix D. Cross -sectional dimensions remained relatively stable between baseline conditions and MY1 monitoring efforts. All Little Pine Creek Reach 1 cross -sections and Tributaries A, B, and C showed evidence of sediment deposition and/or bank forming (Appendix D, Cross -Section overlays and Table 11a). Cross -sections 10 and 12 showed the most drastic difference in dimension due to deposition from multiple storm events during MY2. Riffle dimensions for Reach 2 remained relatively similar between baseline conditions and MY2 monitoring. Similar to Reach 1, new overbank deposits are evident from the cross -sectional surveys (Appendix D, Table 11b). Three areas of bank scour or slumping (110+25, 120+75, and 121+50) were identified at the LPC II Project in MY2. At Station 110+25 the outside bend has notable scour and some bank slump. The second area of instability (Station 120+75) has a similar amount of scour along the outer bend leading to the confluence with Trib D. At the final problem area (Station 121+50) in Reach 2b, the bank at the first set of log -drop structures has a significant amount of scour (Problem area photos and Table 5, Appendix B). This scour is not currently impacting the stability of the structure. The site will continue to be monitored for signs of instability. The water -gate at the beginning of Reach 2A had been damaged during a high flow event and was no longer intact. No areas of encroachment or fence failure were observed during the assessment. The next site visit is planned for spring 2022. 1.5.3 Hydrology Since project completion in late 2019, twelve bankfull events have been documented at the LPC II Site (Table 12, Appendix E). Six events were recorded on Little Pine Creek, and one event was recorded at the Tributary C, and one at Tributary B. Visual evidence of at least one bankfull event was recorded on Trib A during MY2, evidence from wrack lines. This event was not recorded on the crest gauge due to a significant amount of deposition and plugging of the intake orifices. Based on precipitation and stage recorder data the events were recorded over 6 days: March 25t", June 12t", July 2nd, August 8t", August 18t", and October 91", 2021. Groundwater data from both wetland gages met established criteria during MY2. MW 1 at Wetland 1 recorded 142 consecutive days (84.5%) during the MY2 growing season. MW 2 at Wetland 2 recorded 66 consecutive days (39%). Hydrology will continue to be monitored throughout the life of the project. 2.0 METHODS 2.1 Geomorphology Geomorphic measurements were taken during low flow conditions using a Nikon NPR 332 Total Station. Three-dimensional coordinates associated with cross-section data were collected in the field and geo- referenced (NAD83 State Plane feet FIPS 3200). Morphological data were collected at 13 cross -sections. Survey data was imported into CAD, ArcGIS, and Microsoft Excel for data processing and analysis. Channel substrate was characterized using a Wolman Pebble Count as outlined in Harrelson et al (1994) and processed using Microsoft Excel. 2.2 Vegetation Vegetation success in MY2 was monitored at 8 permanent monitoring plots in conjunction with 4 random vegetation plots. Permanent vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008). Data was processed using the NC DMS vegetation tool. In the field, the four corners of each permanent plot were permanently marked with metal t-posts and PVC pipe. Photos of each plot were taken from the plot origin each monitoring year. Random vegetation plots were monitored as per Section V of the Wilmington District Stream and Wetland Compensatory Mitigation Update (USACE 2016). Data is processed analogous to the CVS data entry tool. In the field, the origin corner of each plot were temporarily marked. 2.3 Hydrology Two crest gages, two continuous stage recorders, two groundwater gages, and a rain gage were used to monitor, meteorological, surface, and groundwater within the site. Additionally, visual observations of bankfull event indicators will be documented throughout the project. Data will be recorded and reported through subsequent monitoring reports. 3.0 REFERENCES Harrelson, Cheryl C., Rawlins, C.
