The revised documents are submitted with this letter. Below are responses to each of the comments. For your convenience, the comments are reprinted with responses in italics. 1. Table 2 a. First row states that there are no performance criteria for stream stability. The criteria are BHR below 1.2, ER over 2.2, etc. Response: Stream stability performance criteria in Table 2 has been updated. b. Second row regarding exclusion of livestock. There should be functional uplift associated with removal of livestock. Response: Functional uplift associated with livestock removal has been updated and is included in Table 2. c. Last row indicates that there was no encroachment in MY1 which conflicts with Section 2.2 and the discussion there of the Greensboro Science Center encroachment. Response: The last row of Table 2 has been updated to include the Greensboro Science Center vehicle encroachment. 2. Section 2.6 – States that the growing season for this project was approved at the April 2023 credit release meeting, but this site was not on the April 2023 credit release meeting agenda and the IRT as-built site visit was in May. Was this site discussed at credit release? Please clarify. st – Response: The growing season was approved in the Mitigation Plan and is March 1 th November 21 each year. Section 2.6 has been updated. 3. Figure 1 & 1b – Please show your best estimation of the vehicle encroachment location. Response: Figure 1b has been updated to include approximate location of the vehicle encroachment extent. 4. Can the multiflora rose and privet treatment indicated in Section 2.2 be shown on the CCPV, or were these scattered occurrences? Response: These were small, sporadic occurrences all below the mapping threshold. This has been clarified in the report text. Wildlands Engineering, Inc.

Response:Parrot feather treatment extended over 0.13acres; Table 5 has been updated to include this. 6.Mussel survey indicates that downstream reaches (A & B) and an upstream reach were surveyed. There are only results for 2 reaches. Were the downstream reaches combined? Was this intended? The mitigation plan (Figure 11) shows 3 distinct mussel monitoring locations (upstream of the site, Reach 1, and Reach 2). We suggested requesting a map from the subconsultant that performed the mussel survey showing survey locations. Response:Per the Technical Memorandumsent to the IRT (12/15/2020) in the Liberty Rock Mitigation Plan, only the upstream off-site reach along with a secondoff- sitereach downstream of restoration activities are surveyed in Monitoring Year 1. The 3 sampling points included in the Mitigation Plan (Figure 11), depict which reaches sampling willtake place in. Transects within the reach of those pointsare sampled, as opposed to returning to aspecific riffle. The off- site reach downstream of restoration activities sampled for MY1 is not called out in the Mitigation Plan (Figure 11). Reaches A and B mentioned in the Mussel Survey Report represent the two stream transectsthat were surveyed within theoff-sitereach downstream of restoration activitiesduring MY1. This has been confirmed with the consultant, TranSystems. Amap of MY1 mussel survey locations has been added to this report and will be included withfuture monitoring reports as well.

The Site is located within the Rocky River Headwaters targeted local watershed (TLW) Hydrologic Unit Code (HUC) 03030003070010 and the NC Division of Water Resources (DWR) Subbasin 03-06-12. The Site will provide stream and wetland credits to the Cape Fear River Basin Cataloging Unit (CU) 03030003 through restoration, enhancement, and preservation of the Rocky River and four unnamed tributaries to the Rocky River (referred to as Schist Creek, Gypsum Creek, Dolomite Creek, and Mica Creek for the project) and riparian wetland re-establishment, rehabilitation, and enhancement. The Site is located on 2 parcels owned by one landowner and a conservation easement was recorded on 41.12 acres. 1.1Project Quantities and Credits The Wilmington District Stream Buffer Credit Calculator (updated (1/19/2018) was used to determine final crediting for the “Additional Credit from Extended Buffers” shown in Table 1 below.

As referenced in the Liberty Rock Mitigation Site Final Mitigation Plan, historic aerials indicate that on-site streams have existed in their same approximate location for over 75 years, with some changes to the agricultural management of the land. Aerials show that the riparian buffers for Dolomite, Gypsum, and Schist Creeks have remained undisturbed since prior to 1943. The riparian buffer of Mica Creek was timbered and converted to agricultural use in the 1960’s and the riparian buffer and floodplain of Rocky River was timbered and converted to agricultural use in the 1980’s. The Rocky River was straightened and moved to the south valley edge during that time. Land use and buffer extents have remained consistent since then. A review of historic imagery for the greater Rocky River Watershed draining to the Site shows little land use change since 1993 as well. Nearly 4% of the watershed area is planted pine trees for future harvesting. According to aerial photography, the most recent logging event occurred between 2006 and 2008 when approximately 75 acres of pines in the upper watershed were timbered.

Liberty Rock Mitigation Site Monitoring Year 1 Annual Report - Final1-5 Section 2:MONITORING YEAR 1 DATA ASSESSMENT Annual monitoring and site visits were conducted during MY1 to assess the condition of the project. The vegetation and stream success criteria for the Site follow the approved success criteria presented in the Mitigation Plan (Wildlands, 2021). Performance criteria for vegetation, stream, and hydrologic assessment are located in Section 1.2 Table 2: Goals, Performance Criteria, and Functional Improvements. Methodology for annual monitoring is described in the Monitoring Year 0 Annual Report (Wildlands, 2022). 2.1Vegetative Assessment The MY1 vegetative survey was completed in August 2023. Vegetation monitoring resulted in a stem density range of 364 to 688 planted stems per acre which is well above the interim requirement of 320 stems per acre required at MY3. Average stem density across all vegetation plots was 560 planted stems per acre. All 19 vegetation plots met the interim success criteria and are on track to meet the final success criteria required for MY7. Additionally, herbaceous groundcover has become well established across the site. Refer to Appendix A for Vegetation Plot Photographs and the Vegetation Condition Assessment Table and Appendix B for Vegetation Plot Data. 2.2Vegetation Areas of Concern Vegetation management and herbicide treatments were applied prior to construction in sporadic areas across the site to prevent the spread of invasive species that could potentially compete with planted native species. To further establish invasive treatment effectiveness, small, scattered occurrences of multiflora rose (Rosa multiflora) and Chinese privet (Ligustrum sinense) received follow-up chemical and physical supplemental treatments throughout March-May 2023. Secondly, a vigorous approach has been taken to eradicate Parrot feather (Myriophyllum aquaticum) from the Site and a huge reduction has been observed along Rocky River, with only a 0.13 acre area requiring treatment. Parrot feather treatment included alternating between physical and chemical removal, utilizing glyphosate and triclopyr several times although imazapyr was ultimately most effective for sporadic populations within isolated wetlands. Treated sporadic wetland areas have been reseeded with a wetland winter cover crop mix that has already germinated and begun to grow. Additional physical and chemical removal is planned for these areas throughout 2024. Invasive populations will continue to be monitored and retreated as necessary. Prior to construction, the floodplain along Mica Creek was dominated by pasture grasses. Wildlands proactively treated these areas by chemically burning pasture grasses with 2% glyphosate before seeding in Fall 2022. To further ensure trees outcompete dense herbaceous vegetation, Wildlands has continued to treat these areas with herbicide ring sprays and tree boosters at the drip line around planted trees. This was completed in April 2023 and will continue in this area in early Spring to reduce vegetative competition and promote tree growth. During a Site visit on April 12, 2023, an easement encroachment created by tire tracks was observed along the eastern side of Mica Creek leading toward the confluence of Mica Creek and Rocky River. It has been determined that this was an error made by the Greensboro Science Center, during a NCWRC approved mussel relocation effort. A vehicle was driven inside the conservation easement to the Rocky River stream bank to relocate mussels. Wildlands has contacted the Greensboro Science Center, and this should not be a continued concern. Liberty Rock Mitigation Site Monitoring Year 1 Annual Report - Final2-1 2.3Stream Assessment Morphological surveys for MY1 were conducted in April 2023. Visual assessment shows all streams on Site are stable and functioning as designed. Cross-sections show minimal change in max depth and bankfull cross-sectional area. Cross-sections only show slight deviations from as-built due to sediment deposition and establishment of vegetation post-construction. Cross-section 9 shows slight deviation in bank shape from as-built due to natural settling of the underlying sod mats and sediment. Cross-sections show entrenchment ratios within an acceptable range of the design parameters and bank height ratios are less than 1.2. Specific entrenchment ratio numbers are not included in this report template but are available upon request. Refer to Appendix A for the Visual Stream Morphology Stability Assessment Table and Stream Photographs. Refer to Appendix C for Stream Geomorphology Data. Post-construction mussel surveys for MY1 were conducted by TranSystems on June 9, 2023. Visual and tactile surveying located six different freshwater mussel species. Refer to Appendix F for Additional Documentation and Mussel Survey Report. 2.4Stream Areas of Concern No stream areas of concern were identified, all streams are stable and functioning as intended. 2.5Hydrology Assessment By the end of MY7, four bankfull events must have occurred in separate years on Rocky River and Mica Creek. Two crest gauges were installed initially, one on Rocky River Reach 2 (Enhancement I) and another on Mica Creek. An additional crest gauge was installed on Rocky River Reach 1 on February 21, 2023 during MY1 to better reflect the interaction of flow conditions within the restored portion of the site. A bankfull event was recorded on all three crest gauges in April 2023 and additional events were captured on both Rocky River Reach 2 and Mica Creek during MY1. Additionally, the presence of baseflow must be documented annually on intermittent reaches (Gypsum Creek) for a minimum of 30 consecutive days during a normal precipitation year. Gypsum Creek exceeded this criterion, maintaining baseflow for 199 consecutive days during MY1. Refer to Appendix D for hydrology summary data and the Recorded Bankfull Events Plot. 2.6Wetland Assessment Eleven groundwater gauges were installed in wetlands across the Site. The performance criterion for wetland hydrology is groundwater within 12 inches of the ground surface for 12.0% (31 days) of the growing season consecutively. The growing season for this project has been set as March 1 through November 21 (265 days) and was approved by the IRT in the Mitigation Plan (Wildlands 2021). Per IRT request, groundwater gauge 6 will be relocated to higher ground during winter 2023-2024; the updated location and data will be reported in MY2. Of the eleven groundwater gauges, seven exceeded the success criteria during MY1 with hydroperiods ranging from 12.8% (34 consecutive days) to 55.8% (148 consecutive days). Groundwater gauges 2, 7, 9, and 11 missed the performance criteria with hydroperiods ranging from 1.1% (3 consecutive days) to 5.7% (15 consecutive days). After construction of the stream channel, it is anticipated that the groundwater table will take some time to recharge. Although continued hydrology observation throughout upcoming monitoring years is needed to evaluate success, it is expected that groundwater gauges 2, 7, 9, and 11 will show a positive trend in future monitoring years. 2.7Monitoring Year 1 Summary Overall, the Site looks great, is performing as intended, and is on course to meet success criteria. All vegetation plots are individually on track to exceed the MY3 interim requirement of 320 planted stems Liberty Rock Mitigation Site Monitoring Year 1 Annual Report - Final2-2 per acre. MY1 vegetation plot data shows an average density of 560 planted stems per acre across the Site. Dense herbaceous vegetation has filled in across the floodplain. Ring sprays will be applied around the base of trees in early spring 2024 to continue to help planted trees compete with herbaceous vegetation. Invasive species will continue to be assessed and treated as necessary in future monitoring years. All project streams are stable, functioning as intended, and meeting project goals. Several bankfull events were documented on both Rocky River Reach 2 and Mica Creek and one bankfull event was captured on Rocky River Reach 1. Gypsum Creek had 199 consecutive days of flow, far exceeding success criterion. Seven of the eleven groundwater well gauges surpassed the success criterion, although the remaining four have yet to recharge post-construction and meet criteria. After construction of the stream channel, it is anticipated that the groundwater table will take some time to recharge. They are expected to show a positive trend in subsequent monitoring years. The easement boundary has been walked and no signage issues were observed. One vehicular access easement encroachment from a NCWRC approved mussel relocation effort was observed in April, has been resolved, and is no longer a concern. 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. All raw data supporting the tables and figures in the appendices are available from DMS upon request.

Tagged Freshwater Mussels 1.0INTRODUCTION TranSystems conducted Monitoring Year 1 Post-Construction surveys to evaluate the freshwater mussel communities downstream and upstream of the Liberty Rock stream restoration reach. 2.0SURVEY EFFORTS Survey Efforts Freshwater mussel surveys were completedonJune 9, July 5, 6, and 18, 2023 in the downstream reaches (Reaches A & B), and in the upstream relocation reach to locate and identify resident and relocated freshwater mussels. Surveys were completed using visual and tactile methods. All individuals found were identified and placed back in the stream. Tagged species that were re-captured from pre-construction relocation efforts were recorded, measured and noted as a recaptured individuals. Common species marked during pre- construction relocation efforts that were re-captured were identified and recorded. A catch per unit effort (CPUE) for each species was estimated for each reach. 3.0RESULTS Rocky River-Downstream Reach A total of 1871 freshwater mussels including five species were observed including Eastern Elliptio (Elliptio complanata), Carolina Slabshell (Elliptio congaraea), Florida Pondhorn (Uniomerous carolinianus), Eastern Creekshell (Villosa delumbis), and the Notched Rainbow (Venusticoncha constricta) (Table 1).

Riffle, run, and pool habitats were present throughout the reach. Substrate was dominated by sand, cobble, gravel, and bedrock. No tagged individuals were observed. Three Eastern Creekshell shells and one Notched Rainbow shell were found. Freshwater mussels were observed throughout the stream channel in stable gravel substrate and silty banks. Liberty Rock Enhancement Reach Mussel Survey Report December 2023 Page 1 Rocky River-Upstream Relocation Reach A total of 829 freshwater mussels composed of five species were observed including Eastern Elliptio (Elliptio complanata), Eastern Floater (Pyganodon cataracta), Florida Pondhorn (Uniomerous carolinianus), Eastern Creekshell (Villosa delumbis), and the Notched Rainbow (Venusticoncha constricta) (Table 2).

Riffle, run, and pool habitats were present throughout the surveyed area. Substrate was dominated by sand, silt, cobble, gravel, boulder, and bedrock. A total of 379 marked individuals were recaptured in the relocation reach. 4.0DISCUSSION Six freshwater mussel species were observed during the survey efforts including Eastern Elliptio, Notched Rainbow, Eastern Creekshell, Florida Pondhorn, Carolina Slabshell, and Eastern Floater. The Downstream Reach appeared to be stable with condition similar to the pre- construction period species diversity and abundance. The Upstream Relocation Reach appeared stable with conditions similar to the pre-construction period. 53% of the Eastern Creekshell individuals detected in the relocation reach were recaptures from pre-construction relocation efforts. 75% of Notched Rainbow individuals detected in the relocation reach were recaptures from pre-construction relocation efforts(Appendix A). 45% of the Eastern Elliptio individuals detected were recaptures from pre-construction relocation efforts. 18% of the Florida Pondhorn individuals detected were recaptures, and one untagged Eastern Floater was observed.
