(Wildlands) has reviewed the Division of Mitigation Services’ (DMS) comments from the Draft Monitoring Year (MY) 4 report for the Lone Hickory Mitigation Site. DMS’ comments are noted below in bold. Wildlands’ responses to those comments are noted in italics. DMS’ comment: General: Per the 12/8/2017 IRT approved mitigation plan; “If a gage does not meet the performance standard for a given monitoring year, rainfall patterns will be analyzed and the hydrograph will be compared to that of the reference wetlands to assess whether atypical weather conditions occurred during the monitoring period.” Based on a review of the draft report, reference wetland gauge data for the site has not been collected since November 2020 (MY2). As documented in the MY4 (2022) report, please make every effort to reestablish a functional reference wetland gauge for the site prior to the start of MY5 (2023). The reestablishment and location of the reference gauge should be documented in the MY5 (2023) report. Wildlands’ response: Wildlands will continue to make every effort to reestablish a functional reference wetland gage and will document efforts in the MY5 (2023) report. DMS’ comment: General: The Vegetation Condition Assessment Table (Table 7) indicates that no conservation easement encroachment areas were identified on the project site. In the comment response letter, please confirm that the entire project boundary was walked and assessed by Wildlands staff as part of the MY4 (2022) monitoring effort and no conservation easement encroachments currently exist on the site. Wildlands’ response: The entire project boundary was walked by Wildlands staff as part of the MY4 (2022) monitoring effort and no conservation easements encroachments currently exist on the site. DMS’ comment: Section 1: Project Overview: This section notes; “Tables 11a – 11d in Appendix 4 present the pre-restoration conditions in detail.” These tables are not provided in this year’s monitoring report. Please update the report text accordingly. Wildlands’ response: The text in Section 1 has been updated. Wildlands Engineering, Inc. phone 704-332-7754 fax 704-332-3306 1430 S. Mint Street, # 104 Charlotte, NC 28203 DMS’ comment: Section 1.2.4 Wetland Assessment: In the report text, please indicate that GWG 11, GWG 12, GWG 13, and GWG 14 were installed on 4/22/2022. Wildlands’ response: The text in Section 1.2.4 has been updated. DMS’ comment: Section 1.2.5 Areas of Concern and Management Activities: Please include the wetland indicator status for the species in the February 2022 supplemental planting list. Wildlands’ response: The wetland indicator status has been added for the species in the supplemental planting list. DMS’ comment: CCPV Maps: Please show the two (2) established soil temperature probes on the applicable CCPV map sheets and update the digital support files accordingly. Wildlands’ response: The locations of the two soil temperatures probes have been added to the applicable CCPV figures. The digital GIS files have been updated to include the soil temperature probe feature class. DMS’ comment: Stream Photos MY4 (2022) – The March 14, 2022 photos for UT2B indicate that the channel likely has flow more than 11 consecutive days per year. DMS recommends checking the flow gauge before the start on MY5 (2023) to confirm there are no monitoring equipment or calibration issues. A game camera should also be considered on this reach to document the 30 days of consecutive flow. Wildlands’ response: The photo points taken along UT2B on March 14, 2022 showing flow in the upper portions of the channel are consistent with the stream gage plot that documented consecutive flow between March 9, 2022 and March 18, 2022. Wildlands will be sure to check the stream gage to confirm no issues are present before the start of MY5 (2023) and will consider adding a game camera to document consecutive flow as well. DMS’ comment: Appendix 6 – Table 16: Please add a foot note to the table indicating that GWG 11, GWG 12, GWG 13, and GWG 14 were installed on 4/22/2022. Wildlands’ response: A foot note has been added to Table 16. Digital Support File Comments: DMS’ comment: None Wildlands’ response: Noted Two (2) hard copies of the Final Year 4 Monitoring Report and a full electronic submittal on a USB drive have been mailed to the DMS Western Field Office. Wildlands received a confirmation of approval of the monitoring bond on 1/6/2023 by Kristie Corson at DMS. Therefore, we are requesting approval from DMS to invoice for the completion of Task 10.

Mint Street, # 104 Charlotte, NC 28203 EXECUTIVE SUMMARY Wildlands Engineering, Inc. (Wildlands) implemented a full-delivery stream and wetland mitigation project at the Lone Hickory Mitigation Site (Site) for the North Carolina Department of Environmental Quality (DEQ) Division of Mitigation Services (DMS). The project restored and preserved a total of 12,621 linear feet (LF) of perennial and intermittent stream and restored 9.5 acres of riparian wetland in Yadkin County, NC. The Site is located within the DMS targeted watershed for the Yadkin River Basin Hydrologic Unit Code (HUC) 03040101130020 and the NC Division of Water Resources (NCDWR) Subbasin 03-07-02. The project is providing 13,164.574 stream mitigation units (SMUs) and 9.500 wetland mitigation units (WMUs) for the Yadkin River Basin HUC 03040101 (Yadkin 01). The watershed has a long history of agricultural activity and most of the stressors to stream functions are related to this historic and recent land use practices. The major stream stressors for the Site were concentrated agricultural runoff inputs, active stream incision and head cutting, lack of stabilizing streamside vegetation, extensive agricultural manipulation through ditching, and a lack of bedform diversity. The effects of these stressors resulted in degraded water quality and habitat throughout the watershed of the Site when compared to reference conditions. The project approach for the Site focused on evaluating the existing functional condition, potential for recovery, and need for intervention. The project goals defined in the Mitigation Plan (Wildlands, 2017) were established with careful consideration of 2009 Upper Yadkin Pee Dee River Basin Restoration Priorities (RBRP) goals and objectives to address stressors identified in the watershed. The established project goals include: Improve stream channel stability, Reconnect channels with historic floodplains and re-establish wetland hydrology and function in relic wetland areas, Improve instream habitat, Reduce sediment and nutrient input from adjacent farm fields, Restore and enhance native floodplain and wetland vegetation, and Permanently protect the project site from harmful uses. The Site construction and as-built surveys were completed in April 2019. Monitoring Year (MY) 4 is a reduced monitoring year, so vegetation plot and cross-section data were not collected. Assessments and site visits were completed between February and November 2022 to evaluate the current conditions of the project. The Site is meeting most of the required stream, vegetation, and hydrology success criteria for MY4. While vegetation plots were not assessed this year, the Site is expected to meet the interim MY5 requirement of 260 stems per acre. At least one bankfull event was documented along UT1 Reach 3, UT2 Reach 2, UT2A, and UT3 Reach 3 in MY4. Eleven of the thirteen groundwater gages installed on the Site met or exceeded the hydrologic success criteria for MY4. The MY4 visual assessment identified a few areas of concern including pockets of invasive species populations and isolated areas of bed/bank scour. Wildlands will continue to monitor these areas and adaptive management actions will be implemented as necessary throughout the seven-year monitoring period to maintain the ecological health of the Site.

The project watershed is dominated by agricultural and forested land and located in the Inner Piedmont lithotectonic belt within the Piedmont physiographic province (NCGS, 1985). The Site contains two valleys, separated by a ridge that runs north to south through the project limits. South Deep Creek flows along the northern boundary of the project. On the east side of the ridge (herein referenced as the East Side), UT1 flows through a steep, narrow valley that gradually widens and flattens in slope as it flows downstream to the South Deep Creek floodplain. UT1 is joined by UT1A and UT1B within the Site limits before flowing offsite to join South Deep Creek. On the west side of the ridge (herein referenced as the West Side), UT2 and UT3 flow out of steep, narrow valleys into the broad, flat floodplain of South Deep Creek. UT2B begins downstream of BMP4 and flows into UT2. UT2A and UT2 join UT3 before the stream’s confluence with South Deep Creek. The East Side of the Site drains 0.44 square miles, and the West Side of the Site drains 0.87 square miles of rural land. The Site was historically used for crop production and dairy farming which collectively contributed to degraded in-stream habitat and sediment erosion. On the East Side, streams were manipulated through ditching, impoundments, and land use changes. The West Side streams were ditched and re-routed within the adjacent floodplain which was previously altered for agricultural uses. The riparian buffers on both sides of the Site lacked stabilizing streamside vegetation due to agricultural practices. Construction activities were completed in April 2019 by KBS Earthworks, Inc. Turner Land Surveying, PLLC. completed the as-built survey in April 2019. Planting was completed following construction in the spring of 2019 by Bruton Natural Systems, Inc. A conservation easement has been recorded and is in place on 103 acres. The project is providing 13,164.574 Stream Mitigation Units (SMUs) and 9.500 Wetland Mitigation Units (WMUs) for the Yadkin River Basin 03040101 HUC (Yadkin 01). Annual monitoring will be conducted for seven years with close-out anticipated to commence in 2026 given the success criteria are met. Directions and a map of the Site are provided in Figure 1 and project components are illustrated for the Site in Figure 2. 1.1 Project Goals and Objectives The Site is providing numerous ecological benefits within the Yadkin Valley Basin. The project goals were established with careful consideration to address stressors that were identified in the NCDWR 2008 Yadkin River Basinwide Plan (NCDWR, 2008) and the RBRP (EEP, 2009). The following project specific goals and objectives outlined in the Mitigation Plan (Wildlands, 2017) include: Lone Hickory Mitigation Site Monitoring Year 4 Annual Report - Final1-1 GoalsObjectives Restore stream channels that will maintain a stable pattern and profile considering the hydrologic and sediment inputs to the system, the landscape setting, and the watershed conditions.

The stream, vegetation, and hydrologic success criteria for the Site follows the approved success criteria presented in the Lone Hickory Mitigation Plan (Wildlands, 2017). 1.2.1 Vegetation Assessment MY4 is a reduced monitoring year that does not require detailed vegetation inventory and analysis. Visual assessments reveal that herbaceous cover is becoming well established and planted bare roots and live stakes appear healthy. Previously noted areas of low stem density are improving and discussed further in Section 1.2.5. Please refer to Appendix 2 for visual assessment tables and Current Condition Plan View (CCPV) Figures 3.0-3.5. Lone Hickory Mitigation Site Monitoring Year 4 Annual Report - Final1-2 1.2.2 Stream Assessment MY4 is a reduced monitoring year that does not require morphological surveys; therefore, the stream cross-section surveys were not performed this year. Visual assessments reveal that project streams are functioning as designed. Refer to Appendix 2 for the visual stability assessment tables, CCPV figures, and reference photographs. 1.2.3 Stream Hydrology Assessment At the end of the seven-year monitoring period, four or more bankfull events must have occurred in separate years within the restoration reaches. At least one bankfull event was recorded on UT1 Reach 3, UT2 Reach 2, UT2A, and UT3 Reach 3 in MY4 using stream gage pressure transducers. UT3 Reach 3 has recorded four bankfull events in separate years, while UT1 Reach 3, UT2 Reach 2, UT2A, and UT2B have recorded three bankfull events in separate years thus far. Currently, the Site is on track to meet the hydrologic success criteria for bankfull events, and the criteria has been met for UT3 Reach 3. Consistent flow must be documented in the restored intermittent or low flow channels (UT1 Reach 1, UT2A, and UT2B) at the Site. Under periods of normal rainfall, stream flow must be documented to occur every year for at least 30 consecutive days during the seven-year monitoring period. In MY4, UT1 Reach 1 and UT2A exceeded the success criteria for stream flow with 304 and 123 consecutive days documented, respectively. UT2B was short of meeting the success criteria with 11 consecutive days of flow documented in MY4; however, UT2B did exceed success criteria in MY3 with 43 consecutive days recorded. Please refer to CCPV figures in Appendix 2 for the stream gage locations and Appendix 5 for hydrology summary data and plots. 1.2.4 Wetland Assessment Nine groundwater monitoring gages (GWGs) were initially installed during baseline monitoring within the wetland re-establishment area using In-situ Level TROLL® 100 pressure transducers. Following recommendations from the August 19, 2019 IRT site walk, an additional gage (GWG 10) was installed adjacent to GWG 4, outside of the former ditch location, at the end of October 2019. Reporting for GWG 10 began in MY2 to replace GWG 4. Monitoring for GWG 4 ended in MY2. On April 22, 2022, GWG 11 and GWG 12 were installed to capture groundwater hydrology data within the wetland re-establishment area, and GWG 13 and GWG 14 were installed to document potential additional wetland areas along UT2 Reach 1 that have been created by the project. All monitoring gages are downloaded on a quarterly basis and maintained as needed. Calibration was checked by manually measuring water levels on all gages to validate the recorded data from the pressure transducers. Two soil temperature probes were installed on the Site during baseline monitoring near GWGs 5 and 6. The Site does not contain a rainfall gage; instead, the daily precipitation data was collected from the nearest NC Climate Retrieval and Observations Network of the Southeast Database (NC CRONOS) Station, Yadkinville 0.2 E, NC. A reference gage was originally established in a nearby reference wetland to compare the hydrologic response within the restored wetland areas at the Site. In MY3, Wildlands made multiple attempts to contact the new landowner and obtain permission to access the gage but were unsuccessful. In MY4, Wildlands made several attempts to establish a new functional reference wetland gage within other nearby properties, but unfortunately landowners were unwilling to allow access. Wildlands will continue to make efforts to re-establish a reference wetland gage in MY5. The original performance standard for wetland hydrology from the Mitigation Plan (Wildlands, 2017) is the presence of groundwater within 12 inches of the ground surface for 19 consecutive days (9.2%) of the defined growing season for Yadkin County (April 4 through October 27) under typical precipitation conditions. Of the thirteen GWGs (GWG 1 – 3 and 5 – 14), eleven met or exceeded the success criteria for MY4 with the percentage of consecutive days of the growing season ranging from 9.2 to 56.3%. GWG Lone Hickory Mitigation Site Monitoring Year 4 Annual Report - Final1-3 6 and GWG 7 did not meet the success criteria this year with a result of 7.3% of the growing season for both. Daily rainfall data was obtained from the nearby Yadkinville 0.2 E station (CoCoRaHS NCYD004) which is located approximately 2 miles from the Site. Monthly rainfall data in 2022 indicated lower than normal rainfall amounts in April and June, while higher than normal amounts occurred in February, May, July, and August. The remaining months’ (January, March, September, and October) rainfall amounts fell thth between the 30and 70percentiles for Yadkin County. Please refer to CCPV figures in Appendix 2 for the groundwater gage locations and Appendix 5 for hydrology data and plots. In 2022, the soil temperature data from the onsite soil probes indicate soil temperatures consistently above 41 degrees Fahrenheit by the beginning of March 2022. This was similarly observed in 2021 as well. Onsite leaf out conditions were photo documented on March 30, 2022. Wildlands proposes the growing season be extended to begin a week earlier on March 28, 2022. A majority of the onsite leaves had visibly changed color by November 1, 2022; therefore, the modified growing season was not extended beyond the original end date. An analysis of the modified growing season concluded that of the thirteen GWGs, eleven would meet or exceed the success criteria. GWG 7 and GWG 12 were short of meeting the success criteria by only one day. GWG 12 was installed after the growing season had commenced on April 22, 2022, so it possibly would have met criteria at the beginning of the growing season. For comparison purposes, supplemental groundwater gage plots showing the modified growing season and soil temperature plots are provided in Appendix 6. Please refer to Appendix 2 for leaf out and leaf senescence photographs. 1.2.5 Areas of Concern and Management Activities Vegetation Invasive treatments have been successful in reducing previously noted areas of invasive species; MY4 visual assessments revealed that approximately 99% of the conservation easement is unaffected by invasive populations. However, when present, these species include kudzu (Pueraria montana), Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica), princess tree (Paulownia tomentosa), and tree of heaven (Ailanthus altissima). Additional invasive treatments occurred in July and August 2022 and primarily focused on treating kudzu re-sprouts on the West Side and the other invasive species within the existing wood line along the East Side. Asian spiderwort (Murdannia keisak) was also chemically treated within the project streams in July and August 2022. Additional treatments will continue as needed to help manage and eliminate remaining invasive species populations on the Site. Woody vegetation has become well established on over 99% of the planted acreage. Previously documented areas of low stem density (approximately 0.45 acres or 0.7% of the planted acreage) located around permanent vegetation plots 11 and 16 were supplementally planted in February 2022. See the table below for planting species and quantities. These areas were visually reassessed later in the growing season, and it appears that supplemental stems are surviving and healthy. Therefore, these areas are no longer of concern and should be on track to meet the MY5 density criteria. Soil amendments were also added to the floodplain between UT2A and UT2 to improve planted stem growth.

In MY4, bare areas were seeded and amended to prevent gullies and rills from forming along the left valley of UT1. Streams Repairs were previously completed in MY2 and MY3 to address areas of bank and bed instability along UT3 Reach 1, isolated structure issues along UT1 Reach 1, and headcuts that had formed at the inlets/outlets of BMP3 and BMP4. Please refer to previous monitoring reports for more detailed repair plans and documentation. Visual assessments in MY4 reveal that these repair areas continue to appear stable and functioning as designed. Beaver dams were removed in August 2022 along the very downstream portion of UT3 Reach 3 upstream of its confluence with South Deep Creek. The infrequent inundation caused by the beaver dams at the bottom of the Site has not appeared to have damaged floodplain vegetation or stream stability. Wildlands has contracted with USDA to manage beaver on the Site. Beaver activity will continue to be monitored and managed on the Site through closeout. A few additional minor stream areas of concern are noted were noted in MY4. Some piping was observed at two structures along UT1 Reach 1 but these structures are continuing to hold grade and the majority of structures along this reach are functioning as designed. Three constructed riffles are experiencing some bed scour along UT1 Reach 3 at station 147+50 (XS10) and along UT2 Reach 1 at stations 202+75 (XS15) and 203+10. Log structures located at the end of these riffles are maintaining grade and protecting from additional degradation. The remaining areas of concern are considered minor and will continue to be monitored for signs of instability. Quarterly site visits will continue to be conducted to monitor and address areas of concern. If necessary, future adaptive management will be implemented to improve herbaceous cover and woody stem densities, treat and control invasive plants, and address stream stability issues. Please refer to Appendix 2 for CCPV figures and stream stability and vegetation assessment tables. 1.3 Monitoring Year 4 Summary The Site is meeting most of the required stream, vegetation, and hydrology success criteria for MY4. While vegetation plots were not assessed this year, the Site is expected to meet the interim MY5 requirement of 260 stems per acre. At least one bankfull event was documented along UT1 Reach 3, UT2 Reach 2, UT2A, and UT3 Reach 3 in MY4. Eleven of the thirteen groundwater gages installed on the Site met or exceeded the hydrologic success criteria for MY4. The visual assessment identified a few areas of concern including pockets of invasive species populations and isolated areas of bed/bank scour. Wildlands will continue to monitor these areas and adaptive management actions will be implemented as necessary throughout the seven-year monitoring period to maintain the ecological health of the Site. Lone Hickory Mitigation Site Monitoring Year 4 Annual Report - Final1-5 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 a Trimble handheld GPS with sub-meter accuracy and processed using Pathfinder and ArcGIS. Stream gages were installed in riffles and monitored quarterly. Monitoring methods are in accordance with the United States Army Corps of Engineers (USACE, 2016) standards for mitigation. Vegetation monitoring follows the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008).
