(Wildlands) has reviewed the Division of Mitigation Services (DMS) comments and observations from the Deep Meadow Mitigation Site Draft Year 1 Monitoring Report. The report text has been revised for the final draft to reflect the most current condition of the site. The following are your comments and observations from the report and are noted in Bold. Wildlands' response to those comments are noted in Italics. DMS Comment: Appendix 6- Please include written responses to the IRT comments from the 6/3/2020 IRT email indicating Initial Credit Release approval. These are referenced in the text however there should be a response letter coupled with the comment letter. Wildlands Response: A comment response to the IRT email indicating Initial Credit Release approval has been included in Appendix 6. DMS Comment: Please update the asset tables to reflect the MYO/baseline report format. (Project Components, Length and Area Summations, and Overall Assets Summary). Wildlands Response: The asset table matches the MY0/baseline report format. DMS Comment: If the annual mean for the permanent plots is 482, and the annual mean for the mobile plots is 465, how could the overall annual mean be higher (559) as indicated? Please QAQC the table numbers. Wildlands Response: The overall site annual mean was not calculated correctly in the draft report. The calculations have been QAQC'ed. The overall site annual mean for MY1 was 478. The text and appendices have been updated to reflect this change. DMS Comment: Wildlands notes 10 bankfull events for 2020. While it was a wetter than normal year, if there an explanation of why such an unexpected number of apparent bankfull events occurred in 2020? Please consider confirming bankfull elevations in the field in MY2 due to so many recorded bankfull events. Wildlands Engineering, Inc. • phone 704-332-7754 • fax 704-332-3306 • 1430 S. Mint Street, # 104 • Charlotte, NC 28203 k rV WILDLANDS E N G I N E E R I N G Wildlands Response: While the occurrence of such a large number of bankfull events is uncommon, a definitive explanation, other than it being an unusually wet year and that systems lying in the slate belt tend to be flashier than those in other areas of the Piedmont, is unknown. In order to verify the above average bankfull occurrences at the Site, we reviewed the number of bankfull events that occurred at our other restoration sites located in Union County. Each of them also experienced an unusually high number of gaged bankfull events in 2020, ranging from 8 —10+ occurrences. We feel confident that our results are accurate due to similar results experienced at other restoration sites in Union County and a similar pattern of bankfull occurrences among the stream gages on -site. In addition, there were multiple visual verifications of wrack lines, down vegetation, and alluvial deposition. However, we will re -confirm bankfull elevations at each gaged on -site riffle cross-section during the MY2 survey collection. DMS Comment: Digital Support File Comments: Please submit monitoring photos as JPEGS. Wildlands Response: The photographs have been converted to JPEGS. DMS Comment: Digital Support File Comments: Please add the figure for Stream Gage #1 to the report. Wildlands Response: The figure for Stream Gage #1 has been added to the report. Please note that the gage was accidentally installed above the bankfull elevation as reflected in the plot. Gage #1 will be lowered in the winter of 2020 to capture all events in MY2.

(Wildlands) implemented a full -delivery stream and wetland mitigation project at the Deep Meadow Mitigation Site (Site) for the North Carolina Department of Environmental Quality (DEQ) Division of Mitigation Services (DIMS). The project restored, enhanced, and preserved a total of 4,365 linear feet (LF) of perennial stream in Union County, NC. In addition, the project rehabilitated 0.58 acres and re-established 8.26 acres of riparian wetlands. The Site is located within the DIMS targeted watershed for the Yadkin River Basin HUC 03040105070060 and the NC Division of Water Resources (DWR) Subbasin 03-07-14. The project is providing 2,838.933 stream mitigation units (SMUs) and 8.647 wetland mitigation units (WMUs) for the Yadkin River Basin Hydrologic Unit Code (HUC) 03040105 (Yadkin 05). The Site's immediate drainage area as well as the surrounding watershed has a long history of agricultural activity. Stream and wetland functional stressors for the Site were related to both historic and current land use practices. Major stream stressors for the Site included channel incision and widening, a lack of stabilizing riparian vegetation, a lack of bedform diversity and aquatic habitat, and agricultural related impacts such as channel manipulation or straightening and concentrated run-off inputs from agricultural fields. The primary stressors to the wetlands on the Site were the lack of wetland vegetation, agricultural impact including ditching to drawdown the water table, and the lack of hydrologic connection to the floodplain tributaries and hillside seeps. The effects of these stressors resulted in channel instability, loss of floodplain connection, degraded water quality, and the loss of both aquatic and riparian habitat throughout the Site's watershed when compared to reference conditions. The project approach for the Site focused on evaluating the Site's existing functional condition and evaluating its potential for recovery and need for intervention. The project goals defined in the Mitigation Plan (Wildlands, 2018) were established with careful consideration of 2009 Lower Yadkin Pee Dee River Basin Restoration Priorities (RBRP) goals and objectives to address stressors identified in the watershed through the implementation of stream restoration and enhancement activities and wetland re-establishment and rehabilitation activities, as well as riparian buffer re -vegetation. 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 in -stream habitat, • Reduce sediment and nutrient inputs from adjacent agricultural 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 between September 2019 and November 2020. Monitoring Year (MY) 1 assessments and site visits were completed between August and November 2020 to assess the conditions of the project. Overall, the Site has met the required stream and vegetation success criteria for MY1. The overall average planted stem density for the Site is 478 stems per acre and is on track to meet the MY3 requirement of 320 stems per acre. Geomorphic surveys indicate that cross-section bankfull dimensions closely match the baseline monitoring with some minor adjustments, and streams are functioning as intended. At least one bankfull event was documented on EF1, WF1, and WF2 since the completion of construction. Ten of the eleven groundwater gages met the wetland hydrology success criteria. The MY1 visual assessment identified a few areas of concern including populations of invasive plant species and WDeep Meadow Mitigation Site Monitoring Year 1 Annual Report - FINAL isolated areas of bank scour. Wildlands will continue to monitor these areas, and an adaptive management plan will be implemented as necessary throughout the seven-year monitoring period to benefit the ecological health of the Site.

The project is located within the NC Division of Mitigation Services (DIMS) targeted watershed for the Yadkin River Basin Hydrologic Unit Code (HUC) 03040105070060 and NC Division of Water Resources (DWR) Subbasin 03-07-14. Located in the Slate Belt within the Piedmont physiographic province (NCGS, 1985), the project watershed is dominated by agricultural and forested land. The site contains Meadow Branch, three unnamed tributaries of Meadow Branch, two existing riparian wetlands and ten proposed riparian wetlands. The unnamed tributaries are referred to by Wildlands as West Fork 1 (WF1), West Fork 2 (WF2), and East Fork 1 (EF1). The existing wetlands are referred to as W-HI and W-H2, while the proposed wetlands are named W-El through W-E10. Meadow branch has a gentle (0.22%) unconfined alluvial valley. EF1 transitions from a gentle (1.00%) moderately confined valley at the upstream project limits to an unconfined valley as it approaches Meadow Branch. WF1 and WF2 are also located in unconfined valleys within the project. The two existing riparian wetlands are located in the floodplain of Meadow Branch at the toe of slope. The Site drains approximately 6.99 square miles of rural land. Prior to construction activities, the Site had a history of crop production with on -site stream's adjacent floodplains altered for agricultural uses. These practices resulted in degraded in -stream habitat, sedimentation, and erosion. EF1 was re-routed to the edge of the valley and shortened to join Meadow Branch at a perpendicular angle. Existing wetlands were ditched to improve field drainage and cleared for row crops. Riparian buffers also exhibited a lack of stabilizing streamside vegetation due to agricultural practices. Pre -construction conditions are outlined in Table 4 of Appendix 1 and Table 6 of Appendix 2. The final mitigation plan was submitted and accepted by DIMS in January of 2018 and the IRT in May of 2018. Construction activities were completed in September 2019 by Land Mechanic Designs, Inc. Kee Mapping and Surveying completed the as -built survey in December 2019. Planting was completed following construction in January 2020 by Bruton Natural Systems, Inc. A conservation easement has been recorded and is in place on 23.8 acres. The project is providing 2,838.933 stream mitigation units (SMUs) and 8.590 wetland mitigation units (WMUs) for the Yadkin River Basin HUC 03040105. Annual monitoring will be conducted for seven years with close-out anticipated to commence in 2027 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 DWR 2008 Yadkin River Basinwide Plan (NCDWR, 2008). The following project specific goals and objectives outlined in the Mitigation Plan (Wildlands, 2018) include: WDeep Meadow Mitigation Site Monitoring Year 1 Annual Report - FINAL 1-1 Goals Objectives Restore stream channels that will maintain a stable pattern and Improve stream channel stability. 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 Deep Meadow Mitigation Plan (Wildlands, 2018). 1.2.1 Vegetation Assessment Vegetation plot monitoring is being conducted in post -construction monitoring years 1, 2, 3, 5, and 7. Permanent plots are monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008) and the 2016 USACE Stream and Wetland Mitigation Guidance to assess the vegetation success. A total of 12 permanent vegetation plots were established within the project easement area using 10-meter by 10-meter square plots. In addition, 4 mobile vegetation plots were established in monitoring year 1 throughout the planted conservation easement to evaluate the random vegetation performance for the Site. These plots will be subsequently reestablished in different random locations in monitoring years 2, 3, 5, and 7. Mobile vegetation plot assessments will document stems, species, and height using 100-meter2 circular, square, or rectangular plots. The final vegetative performance standard will be the survival of 210 planted stems per acre in the planted riparian areas at the end of the required seven-year monitoring period. 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 MY3 and at least 260 stems per acre at the end of MYS. The MY1 vegetation survey was completed in August 2020, resulting in an average planted stem density of 478 stems per acre for all monitored permanent and mobile vegetation plots. The Site is on track to meet the interim MY3 requirement of 320 planted stems per acre, with all plots (100%) individually exceeding this requirement with densities ranging from 364 to 567 planted stems per acre. In the permanent vegetation plots and mobile vegetation plots stems appear to be thriving with a vigor of 3 or WDeep Meadow Mitigation Site Monitoring Year 1 Annual Report - FINAL 1-2 greater indicating that they have good or better plant health and damage is rare. Please refer to Appendix 2 for vegetation plot photographs and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern and Management Activity Overall, the herbaceous cover is becoming well established throughout the site and wetland vegetation has filled in nicely in wet seeps preventing the potential for rills or gullies from forming. No bare areas or areas of low woody stem density were noted. There are isolated areas of native in -stream vegetation on EF1, but this will likely be shaded out as the stream channel develops a stream canopy. The MY1 visual assessments did indicate that some invasive plant populations are present within the conservation easement. The predominant invasive species found on the Site is Johnson grass (Sorghum holepense) totaling 7.2% of the conservation easement acreage in MY1. Though these areas of Johnson grass had previously been treated before construction, they re -sprouted during MY1. Adaptive management activities will occur in MY2 to treat invasive plant areas, as needed. These vegetation areas of concern are documented on Table 7 and shown on the Current Condition Plan View (CCPV) Figures 3.0-3.2 in Appendix 2. 1.2.3 Stream Assessment Riffle cross -sections on the restoration and enhancement I reaches should be stable and show little change in bankfull area, maximum depth ratio, and width -to -depth ratio. All riffle cross -sections should fall within the parameters defined for the designated stream type. If any changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of instability. Indicators of instability include a vertically incising thalweg and/or eroding channel banks. Remedial action would not be taken if channel changes indicate a movement toward stability. Morphological surveys for MY1 were conducted in August 2020. Cross-section survey results indicate that channel dimensions are stable and functioning as designed on all restoration and enhancement I reaches with minimal adjustments. Minor changes occurring within some cross -sections include downcutting, narrowing of riffles, and alluvial deposition at the top of bank. All cross -sections on EF1 and WF1 are stable with minor adjustments to bankfull area, bankfull width and bankfull depth in MY1. Cross-section 6 has had a slight decrease in cross -sectional area and channel depth since MYO likely due to migration of sediment and gravels form the upstream crossing. See section 1.2.5 for additional information about the upstream crossing. Reachwide pebble counts along all restoration and enhancement I reaches indicate maintenance of coarser materials in riffle features and finer particles in the pool features. Please refer to Appendix 2 for the visual stability assessment tables, CCPV Figures 3.0 — 3.2, and stream photographs, and Appendix 4 for the morphological tables and plots. 1.2.4 Stream Hydrology Assessment Automated pressure transducers were installed to document stream hydrology and used on mitigation reaches that implement restoration and/or enhancement level I approaches throughout the seven-year monitoring period. Henceforth, these devices are referred to as "crest gages (CG)" for those recording bankfull events. At the end of the seven-year monitoring period, four or more bankfull flow events must have occurred in separate years within the restoration reaches. A total of 3 CGs were installed along restoration and enhancement I reaches, were programmed to record data every 3 hours, and captured many high flow events throughout the first year of monitoring. In MY1, at least one bankfull event was recorded on all monitored reaches (EF1, WF1, and WF2), with multiple events being documented on EF1 and WF2 by automated crest gages. Because the automated WDeep Meadow Mitigation Site Monitoring Year 1 Annual Report - FINAL 1-3 pressure transducer, CG1, was accidentally installed above the bankfull elevation along channel WF1 in MYO, only one bankfull event verified with photo documentation was included for Reach WF1 in Table 14. The photos capture deposition on plant material and wrack material around CG1 on WF1. CG1 will be lowered in the winter of 2020 to capture all events in MY2. Please refer to Appendix 5 for hydrology summary data, plots, and photographic evidence of bankfull events. 1.2.5 Stream Areas of Concern and Management Activity All streams on the Site remained stable during multiple large storm events that occurred during 2020. The Site's visual assessment was conducted the day after a 1.7-inch storm event that occurred on 11/13/2020 and the majority of the structures were still intact, and the channels had remained stable. However, MY1 visual stream assessments did reveal a few areas of concern and include localized instances of bank scour on WF2 and EF1. Currently, WF2 and EF1 are 96% and 97% stable, respectively, and performing as intended. Also, in the left floodplain, just upstream of the Meadow Branch ford crossing, an ephemeral drainage that begins outside of the conservation easement and leads to Meadow Branch is scouring the floodplain. The issues mapped on the CCPV figures are as follows: WF2 is experiencing slight aggradation from large storm events washing gravel from the upstream crossing into the channel. EF1 has one brush -toe structure issue located at station 212+00 where floodplain flows are washing behind the structure creating a scour pocket. On Meadow Branch the structure at 103+50 appears to have been washed out entirely. This area appears stable and will be monitored in future years for signs of instability. Wildlands will continue to monitor these areas and remedial actions will be implemented if areas of concern begin to threaten the stability of the project. Stream areas of concern that are noted in this report and on the CCPV figures will continue to be monitored in future years for signs of accelerated instability. If instability is observed, the area will be addressed and evaluated for effectiveness in the MY2 report. Please refer to Appendix 2 for stream stability tables, area of concern photos, and CCPV Figures 3.0— 3.2. 1.2.6 Wetland Assessment Eleven groundwater monitoring gages (GWGs) were installed during baseline monitoring within the wetland re-establishment area using In -situ Level TROLL® 100 pressure transducers. A reference gage was established in a nearby reference wetland and will be utilized to compare the hydrologic response within the restored wetland areas at the Site. All monitoring gages are downloaded on a quarterly basis and maintained as needed. Calibration was completed by manually measuring water levels on all gages which confirmed the downloaded data. The Site does not contain a rainfall gage; therefore, the daily precipitation data was collected from closest USGS gage, 3506270804 10645 CRN-39, located at the NCDOT facility in Matthews NC. The final performance standard for wetland hydrology will be a free groundwater surface within 12 inches of the ground surface for 23 consecutive days (10% percent) of the defined growing season for Union County (March 23 through November 6) under typical precipitation conditions. 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 analyzed in the Deep Meadow Mitigation Plan (2018) to assess whether atypical weather conditions occurred during the monitoring period. Of the eleven GWGs that were installed during baseline monitoring, all, except GWG 11 located in W-E6, met the success criteria for MY1 with a range of 10.9% to 100% of the growing season. GWG11 missed WDeep Meadow Mitigation Site Monitoring Year 1 Annual Report - FINAL 1-4 meeting the success criteria by 3 days this year. Monthly rainfall data in 2020 indicated higher than normal rainfall amounts occurred during the months of February, April, May, July and October. In response to a comment received from the Interagency Review Team (IRT) in reference to well locations documented in the Baseline Monitoring Report (Wildlands, 2020), GWGs 3 and 11 are located just outside of the wetland establishment areas for W-E6 and W-E8, respectively. The current location of these wells is as close to the Mitigation Plan's proposed gage location as possible. Multiple holes were bored in the areas surrounding the Mitigation Plan's proposed gage locations; however, installation was difficult due to a shallow layer of bedrock where refusal was reached at approximately 3 - 4 feet. Though the resulting locations for GWG3 and GWG11, at the edge of the proposed wetland boundary, is not optimal, it is the assumption that if the wetland meets criteria on the edge wetland boundary, the remainder of the wetland will also meet. This was the case for GWG3; however, GWG 11 just barely missed meeting the success criteria of 10% with a rate of 8.7%. If GWG11 continues to not meet the success criteria for wetland hydrology in subsequent monitoring years, Wildlands will install another well closer to the center of W-E6. Please refer to Appendix 2 for the groundwater gage locations on figures 3.0-3.2 and the groundwater gage photographs. Please refer to Appendix 5 for groundwater hydrology data and plots and Appendix 6 for documentation of IRT correspondence. 1.3 Monitoring Year 1 Summary Overall, the Site has met the required stream, vegetation, and hydrology success criteria for MY1. The overall average planted stem density for the Site is 478 stems per acre and is on track to meet the MY3 requirement of 320 stems per acre. Geomorphic surveys indicate that cross-section bankfull dimensions closely match the baseline monitoring with some minor adjustments, and the streams are functioning as intended. At least one bankfull event was documented on all project streams since the completion of construction. The MY1 visual assessment identified a few areas of concern including populations of invasive plant species and isolated areas of bank scour and aggradation. Wildlands will continue to monitor these areas, and an adaptive management plan will be implemented as necessary throughout the seven-year monitoring period to benefit the ecological health of the Site. WDeep Meadow Mitigation Site Monitoring Year 1 Annual Report - FINAL 1-5 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. Hydrologic monitoring instrument installation and monitoring methods are in accordance with the United States Army Corps of Engineers (USACE, 2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008).

Cross -sections were permanently marked with rebar to establish location. Surveys include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg. 2. Pattern and profile will be assessed visually during semi-annual site visits. Longitudinal profile was collected during the as -built baseline monitoring survey only, unless observations indicate widespread lack of vertical stability (greater than 10% of reach is affected) and profile survey is warranted in additional years to monitor adjustments or survey repair work. 3. Riffle 100-count substrate sampling were collected during the baseline monitoring only. A reach -wide pebble count will be performed on each restoration or enhancement I reach each year for classification purposes. 4. Crest gages and/or transducers will be inspected and downloaded quarterly or semi-annually. Evidence of bankfull events such as rack lines or floodplain deposition will be documented with a photo when possible. Transducers, if used, will be set to record stage once every three hours. 5. Permanent vegetation monitoring plot assessments will follow CVS Level 2 protocols. Mobile vegetation monitoring plot assessments will document number of planted stems, height, and species using a circular or 100 m2 square/rectangular plot. 6. Locations of exotic and nuisance vegetation will be mapped. 7. Locations of vegetation damage, boundary encroachments, etc. will be mapped. APPENDIX 2.

Good morning, The 15-Day Record Drawing review for the Deep Meadow Mitigation Site (SAW-2012-01077) ended May 30, 2020. Per Section 332.8(o)(9) of the 2008 Mitigation Rule, this review followed the streamlined review process. All comments received from the NCIRT are incorporated in this email. Please address IRT concerns in the MY1 Report. There were nc objections to issuing the initial credit release. Please find attached the current signed ledger. DWR Comments, Erin Davis: Groundwater gauges 3 and 11 appear to be located outside of wetland reestablishment credit areas. If these gauges were placed to demonstrate additional wetland area, that's fine. But DWR would like groundwater gauges installed within the reestablishment areas W-E6 and W-E8 as specified in the approved mitigation plan to demonstrate success of the wetland hydroperiod performance standard. EPA Comments, Todd Bowers: Thank you for the opportunity to review and provide feedback on the Deep Meadow Mitigation Site MY 0/As-Built Report as a component of the North Carolina Division of Mitigation Services In -Lieu Fee program modification (SAW- 2012-01077). The project, located in Union County NC, restored, enhanced and preserved a total of 4,365 linear feet of perennial stream and rehabilitated 0.58 acres and re-established 8.26 acres of riparian wetlands. The project is providing 2,838.933 stream mitigation units and 8.590 wetland mitigation units for the Yadkin River Basin Hydrologic Unit Code 03040105 (Yadkin 05). The Site construction and as -built surveys were completed between September and November 2019 and planting and baseline vegetation data collection occurred between November 2019 and January 2020. After a thorough review, the EPA Region 4 Oceans, Wetlands and Stream Protection Branch has no comments or concerns with the MYO Report for the Deep Meadow mitigation site. The report appears to be in order and presents a well built and thus far, well performing site with much potential for functional uplift of aquatic resources. Please contact the mitigation office if you have any questions.

(Wildlands) has reviewed the 15-Day Record Drawing review comments from the NC Interagency Review Team (IRT) associated with the Deep Meadow Mitigation Site Initial Credit Release. The MY1 report text includes responses to the IRT comments. Responses are also included below. The following are your comments and observations from the report and are noted in Bold. Wildlands' response to those comments are noted in Italics. DWR Comment, Erin Davis: Groundwater gauges 3 and 11 appear to be located outside of wetland reestablishment credit areas. If these gauges were placed to demonstrate additional wetland area, that's fine. But DWR would like groundwater gauges installed within reestablishment areas W-E6 and W-E8 as specified in the approved mitigation plan to demonstrate success of the wetland hydroperiod performance standard. Wildlands Response: The current location of these wells is as close to the Mitigation Plan's proposed gage location as possible. Multiple holes were bored in the areas surrounding the Mitigation Plan's proposed gage locations, however, installation was difficult due to a shallow layer of bedrock where refusal was reached at approximately 3 - 4 feet. Though the resulting locations for GWG3 and GWG11, at the edge of the proposed wetland boundary, is not optimal, it is the assumption that if the wetland meets criteria on the edge wetland boundary, the remainder of the wetland will also meet. Results from groundwater monitoring from MY1 are reflective of this assumption with GWG3 meeting the performance criteria and GWG11 just barely missing the success criteria of 10% with a rate of 8.7%. If GWG11 continues to not meet the success criteria for wetland hydrology in subsequent monitoring years, Wildlands will install another well closer to the center of W-E6.
