(Wildlands) has reviewed the Division of Mitigation Services (DMS) comments from the Draft Monitoring Year 6 report for the Henry Fork Mitigation Project. DMS' comments are noted below in bold. Wildlands' responses to those comments are noted in italics. DMS' comment: 1.2.3 Vegetative Assessment: Please include a brief discussion regarding the average vegetation height in the three vegetation plots established in the potential wetland areas. The IRT indicated in an email dated December 18, 2020 (Appendix 6) that a vigor standard of 10' high by MY7 is expected. Does WEI think this standard will be met by MY7? Wildlands' response: Text regarding the average vegetation height in the three vegetation plots in the potential wetland areas was added to Section 1.2.3. The average stem heights have also been added to the bottom of Table 9d. The average stem heights for each plot ranged from 3.4 to 4.9 feet, with an overall average of 4.3 feet. Wildlands is undecided if the standard will be met by MY7. DMS' comment: 1.2.4 Wetland Assessment: GWG4 did not meet success criteria due to a malfunction. The data trend prior to the malfunction indicates that GWG4 would have likely met success criteria if not for the malfunction. DMS recommends downloading gage data prior to the 2022 credit release meeting if possible to provide an update. Wildlands' response: Wildlands agrees that GWG4 would have likely met success criteria if not for the transducer malfunction. Wildlands will download the GWG4 data prior to the 2022 credit release meeting to provide an update. DMS' comment: 1.2.5 Areas of Concern: The March 2021 supplemental planting effort included 135 bare roots, 85 tubling plants and 135 live stakes within the potential wetland addendum areas. Please provide a species/quantities list or table and include planting acreage. Wildlands Engineering, Inc. • phone 704-332-7754 • fax 704-332-3306 • 1430 S. Mint Street, # 104 • Charlotte, NC 28203 witow, WILDLANDS ENGINEERING Wildlands' response: A table has been added to Section 1.2.5 to specify the species and quantities of the supplemental planting effort in the potential wetland addendum areas. The approximate planting acreage has also been added to the text. DMS' comment: 1.2.5 Areas of Concern: The frisbee golf footpath was discussed at the 2019 IRT site visit and it was decided the path must be discontinued by the time of closeout. DMS recommends working with the adjacent landowner to discontinue the path early in MY7. WEI would benefit by demonstrating that the path has been decommissioned and is no longer a conservation easement encroachment as the project moves to closeout. Historically, conservation easement encroachments can lead to delayed closeout, additional monitoring to prove encroachment is no longer a problem and stewardship transfer issues. Wildlands' response: Wildlands PM has discussed this matter with the Wildlands' Principal for the project. Wildlands understands the concerns surrounding this use and the potential ramifications for closeout and will deal with this matter accordingly. DMS' comment: CCPV: Please add locations of beaver dams that were removed, bank repair location and supplemental planting areas to CCPV. Wildlands'response: The locations of beaver dams that were removed, bank repair, and supplemental planting areas have been added to the CCPV figures. DMS' comment: Tables Sa-e and 6: Please add the date that the assessment work was completed to the top of each table. The IRT requested this information be included at the 2021 Credit Release Meeting. Wildlan ds' response: The assessment dates have been added to the top of Tables 5a-e and 6. DMS' comment: Stream Gage 2 — UT1 R2: Please add consecutive day bar at top of graph as shown on other gage plots. Wildlands' response: The consecutive day bar has been added to the stream gage 2 plot for UT1 Reach 2. Digital Files Review DMS' comment: Please change the Year —observed field in the SAOC and VAOC feature classes to years observed (e.g. MY1, MY2, etc.) for clarity. Wildlands' response: A field called "Year present" has been added to SAOC and VAOC feature classes in CCPV GIS support files. DMS' comment: The feature representing the scoured region along UT1 Reach 2 has a length of 10 ft relative to the 15 ft reported in Table 5b. Please ensure that feature and table lengths are consistent for final submittal. Wildlands' response: The length reported in Table 5b has been updated to 10 ft so that it is consistent with the feature length in the CCPV.

Sincerely, #'Wo- A cl4k- Jake McLean Project Manager jmclean@wildlandseng.com Wildlands Engineering, Inc. • phone 704-332-7754 • fax 704-332-3306 • 1430 S. Mint Street, # 104 • Charlotte, NC 28203 EXECUTIVE SUMMARY Wildlands Engineering Inc. (Wildlands) implemented a full delivery project at the Henry Fork Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DMS) to restore 3,057 linear feet (LF) of perennial streams and enhance 2,626 LF of intermittent streams, enhance 0.68 acres of existing wetlands, rehabilitate 0.25 acres of existing wetlands, and re-establish 3.71 acres of wetlands in Catawba County, NC. The Site is expected to generate 4,807.667 stream mitigation units (SMUs) and 4.222 wetland mitigation units (WMUs) (Table 1). The Site is located near the City of Hickory in Catawba County, NC, in the Catawba River Basin eight -digit Cataloging Unit (CU) 03050102 and the 14-digit Hydrologic Unit Code (HUC) 03050102010030 (Figure 1). The project's compensatory mitigation credits will be used in accordance with the In -Lieu Fee (ILF) Program Instrument dated July 28, 2010, the expanded service area as defined under the September 12, 2006 PACG memorandum, and/or DMS acceptance and regulatory permit conditions associated with DMS ILF requirements. Hydrologic Unit Code (HUC) 03050102010030, Lower Henry Fork, was identified as a Targeted Local Watershed (TLW) in the DMS 2007 Catawba River Basin Restoration Priority (RBRP) Plan. The project streams consist of four unnamed tributaries (UTs) to the Henry Fork River on the site of a former golf course, referred to herein as UT1, UT2, UT1A, and UT1B (Figure 2). The project also consists of several wetland restoration components, as well as buffer planting along Henry Fork. The project watershed consists of agricultural, forested, and residential land uses. The project goals established in the Mitigation Plan (Wildlands, 2015) were completed 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 within the watershed. The established project goals include: • Permanently protect the project site from harmful uses; • Correct modifications to streams, wetlands, and buffers; • Improve and re-establish hydrology and function of previously cleared wetlands; • Reduce current erosion and sedimentation; • Reduce nutrient inputs to streams and wetlands and downstream water bodies; • Improve instream habitat; and • Provide and improve terrestrial habitat and native floodplain forest. The Site construction and as -built surveys were completed between November 2015 and March 2016. Monitoring Year (MY) 6 assessments and site visits were completed between January and November 2021. Per Inter -agency Review Team (IRT) guidelines, detailed monitoring and analysis of vegetation and channel morphology were omitted during MY6. Visual observations, hydrology data, and management practices are included in this report. To preserve the clarity and continuity of reporting structure, this report maintains section and appendix numbering from previous monitoring reports. Omitted sections are denoted in the table of contents. Overall, the Site has met the required stream and vegetation success criteria for MY6. All restored and enhanced streams are stable and functioning as designed. All project streams recorded at least one bankfull event or greater in MY6. The bankfull performance standard was met for the Site in MY4. Vegetation within the planted riparian areas appear to be performing well with the majority of the acreage on track to meet the MY7 density requirement of 210 stems per acre. Thirteen of the fifteen groundwater monitoring gages installed on the Site met or exceeded the hydrologic success criteria for MY6. The MY6 visual assessments revealed a few areas of concern including pockets of invasive plant species, areas of low stem growth, and beaver activity. These areas will continue to be monitored and adaptive management will be performed as needed.

Access to the Site is via Mountain View Road, approximately one mile southwest of Hickory, North Carolina. Situated in the Inner Piedmont Belt of the Piedmont Physiographic Province (USGS, 1998), the project watershed consists of agricultural, forested, and residential land uses. The drainage area for the Site is 178 acres (0.28 square miles). The project streams consist of four unnamed tributaries (UTs) to the Henry Fork River on the site of a former golf course, referred to herein as UT1, UT2, UT1A, and UT1B. Stream restoration reaches included UT1 (Reach 1 and 2) and UT1B, together comprising 3,057 linear feet (LF) of perennial stream channel. Stream enhancement reaches included UT1A and UT2, together totaling 2,626 LF. Stream enhancement activities for UT1A and UT2 were the same as restoration reaches; however, the tributaries are intermittent and were credited as enhancement. The riparian areas of the tributaries and a 100-foot-wide buffer along the project side of Henry Fork, were planted with native vegetation to improve habitat and protect water quality. Wetland components included enhancement of 0.68 acres of existing wetlands, rehabilitation of 0.25 acres of existing wetlands and re-establishment of 3.71 acres of wetlands. Construction activities were completed by Land Mechanic Designs, Inc. in March 2016. Planting and seeding activities were completed by Bruton Natural Systems, Inc. in March 2016. A conservation easement has been recorded and is in place on 48.06 acres (Deed Book 03247, Page Number 0476- 0488) within a tract owned by WEI-Henry Fork, LLC. The project is expected to generate 4,807.667 Stream Mitigation Units (SMUs) and 4.222 Wetland Mitigation Units (WMUs). Annual monitoring will be conducted for seven years. Close-out is anticipated to commence in 2023 given the success criteria are met. Appendix 1 provides more detailed project activity, history, contact information, and watershed/site background information for this project. 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 will help meet the goals for the watershed outlined in the RBRP and provide numerous ecological benefits within the Catawba River Basin. While many of these benefits are limited to the Henry Fork 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 established were completed with careful consideration of goals and objectives that were described in the RBRP and to meet the DMS mitigation needs while maximizing the ecological and water quality uplift within the watershed. The following project specific goals established in the Mitigation Plan (Wildlands, 2015) include: • Permanently protect the project site from harmful uses; and • Correct modifications to streams, wetlands and buffers; • Improve and re-establish hydrology and function of previously cleared wetlands; • Reduce current erosion and sedimentation; • Reduce nutrient inputs to streams and wetlands, and to downstream water bodies; • Improve instream habitat; and ' a - Henry Fork Mitigation Site `4' Monitoring Year 6 Annual Report— FINAL 1-1 • Provide and improve terrestrial habitat and native floodplain forest. The project goals were addressed through the following project objectives: • Decommissioning the existing golf course and establishing a conservation easement on the Site will eliminate direct chemical fertilizer, pesticide, and herbicide inputs; • Resizing and realigning channels to address stream dredging and ditching. Planting native woody species in riparian zones which have been maintained through mowing. By correcting these prior modifications, the channels and floodplains will provide a suite of hydrologic and biological function; • Restoring appropriate stream dimensions and juxtaposition of streams and wetlands on the landscape. Wetlands will be enhanced through more frequent overbank flooding, and by reducing the drawdown effect that current ditched channels have on wetland hydrology; thereby, enhancing wetland connectivity to the local water table. The project will extend existing wetland zones into adjacent areas and support wetland functions; • Removing historic overburden to uncover relic hydric soils. Roughen wetland re-establishment. Restore streams for wetland benefit. Each of these will bring local water table elevations closer to the ground surface. Create overbank flooding and depressional storage for overland and overbank flow retention. Decrease direct runoff, and increase infiltration; • Planting a native vegetation community on the Site to revegetate the riparian buffers and wetlands. Conduct soil restoration through topsoil harvesting and reapplication and leaf litter harvesting and application from adjacent forested areas. This will return functions associated with buffers and forested floodplains, as well as enhance soil productivity and bring native biological activity and seed into the disturbed areas; • Constructing diverse and stable channel form with varied stream bedform and installing habitat features, along with removing culverts. These will allow aquatic habitat quality and connectivity enhancement; and • Placing a portion of the right bank Henry Fork floodplain under a conservation easement, and planting all stream buffers and wetlands with native species. Creating a 100-foot wide corridor of wooded riparian buffer along that top right bank area and re-establishing native plant communities and habitat connectivity within Site to adjoining natural areas along the river corridor. 1.2 Monitoring Year 6 Data Assessment Annual monitoring was conducted between January and November 2021 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 Henry Fork Mitigation Plan (Wildlands, 2015). 1.2.1 Stream Assessment MY6 is a reduced monitoring year that does not require morphological surveys; therefore, the stream assessment was not performed this year. Visual assessments reveal that project streams are functioning as designed. Refer to Appendix 2 for visual assessment tables, Current Conditions Plan View (CCPV) Figures 3.0-3.2, and reference photographs. 1.2.2 Stream Hydrology Assessment At the end of the seven-year monitoring period, two or more bankfull events must have occurred in separate years within the restoration reaches. The bankfull performance standard was met for the project in MY4. During MY6, all stream reaches recorded at least one additional bankfull event. ' a - Henry Fork Mitigation Site `4' Monitoring Year 6 Annual Report— FINAL 1-2 In addition to monitoring bankfull events, intermittent streams (UT1A and UT2) must be monitored to demonstrate a minimum of 30 consecutive days of flow during periods of normal rainfall. In MY6, UT1A and UT2 both exceeded the success criteria for stream flow with 319 and 169 days documented, respectively. The presence of baseflow was also observed on these reaches during site visits; thereby, confirming the recorded stream gage data. Please refer to CCPV Figures 3.0-3.2 in Appendix 2 for stream gage locations and Appendix 5 for hydrology summary data and plots. 1.2.3 Vegetative Assessment A total of 15 vegetation plots (VPs) were established during baseline monitoring within the project easement area using standard 10 by 10 meter plots. Vegetation plots are monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008). The final vegetative performance standard will be the survival of 210 planted stems per acre in the planted riparian and wetland corridor at the end of the required seven-year monitoring period. In addition, planted vegetation must average 10 feet in height in each plot at the end of the seven-year monitoring period. MY6 is a reduced monitoring year that does not require detailed vegetation inventory and analysis. Therefore, the 15 vegetation plots (VPs) that were originally established during baseline monitoring were not assessed this year. A wetland addendum letter was submitted to DMS on October 6, 2020 to identify potential wetland areas created by the project within the Site. See Section 1.2.5 for further discussion of the wetland addendum. In MY6, 3 vegetation plots were installed within the potential wetland areas as requested by the IRT in the comments to the wetland addendum. These additional wetland vegetation plots (WPs) will be used to evaluate stem density, species diversity, and height to determine if the potential wetland areas are meeting the vegetation success criteria for the Site. An assessment of the WPs was completed in September 2021 and resulted in an average stem density of 540 stems per acre and average height of 4.3 feet. All WPs are exceeding the final vegetative density performance standard for the Site but have not yet met the height performance standard. Please refer to Appendix 2 for wetland vegetation plot photographs, CCPV Figures 3.0-3.2 for vegetation plot locations, and Appendix 3 for wetland vegetation data tables. 1.2.4 Wetland Assessment Following construction, groundwater gages (GWGs) were distributed so the data collected would provide a reasonable indication of groundwater levels throughout the wetland components on the Site. Additional gages have been added to further refine this data. A gage was established in an adjacent reference wetland to compare to the hydrologic response within the restored wetland areas at the Site. A barotroll logger is used to calibrate groundwater gage pressure based on local atmospheric pressure. A new barotroll was installed onsite at the beginning of MY6 to replace the original barotroll that failed in MYS. The rainfall data is collected from an existing NC CRONOS station (Hickory 4.8 SW, NC). All monitoring gages were downloaded quarterly and are maintained as needed. A soil temperature gage was installed on Site in October 2016. Wildlands is using the soil temperature gage data to confirm the dates defined in the WETS table for Burke County, NC, if needed. The WETS growing season is not available for Catawba County and instead, the Burke County growing season (March 20 to November 11) is being used as criteria for hydrologic success. The growing season is defined by historic weather data collected at the Hickory Regional Airport in Burke County, approximately 3 miles as the crow flies from the Site. The final performance standard established for wetland hydrology will be a free groundwater surface within 12 inches of the ground surface for 20 consecutive days (8.5%) of the defined growing season under typical precipitation conditions. ,a - Henry Fork Mitigation Site `� Monitoring Year 6 Annual Report— FINAL 1-3 There are fifteen GWGs currently installed on the Site. Seven of the groundwater hydrology gages (GWGs) were established during baseline monitoring within the wetland rehabilitation and re- establishment zones (GWGs 1— 4 and 6 — 8). During the initial GWG installation, GWG 3 was installed in a seep where hydrology was much stronger than the surrounded area. Wildlands relocated GWG 3 in January 2017 (MY2) to an area more representative of the surrounding wetlands. Wildlands also installed two additional gages (GWG 5 and 9) within the wetland re-establishment areas during 2017 (MY2) to further assess wetland performance near GWGs not meeting criteria. The transducer for GWG 5 showed abnormal data patterns in MY3 and was replaced at the beginning of MY4 to ensure accurate water level data is being reported. In February and March 2019 (MY4), six additional GWGs were added to the Site. Three of the gages (GWG 10 —12) were installed to better define the wetland re- establishment area within the right floodplain of UT1 Reach 2. The remaining three gages (GWG 13 — 15) were installed in locations adjacent to wetland enhancement areas to provide groundwater data to support the potential expansion of these wetland areas. Of the fifteen GWGs, thirteen met the success criteria for MY6 with a range of 13% to 100% of the growing season. GWGs 5, 10, and 13 achieved the success criteria for 100% of the growing season with plots showing similar hydroperiods and indicating comparable groundwater hydrology in those areas. The remainder of the GWG hydroperiods were largely analogous to the reference gage. GWG 8 did not meet the success criteria for MY6 with a measured maximum 18 consecutive days during the growing season or two days short of the success criteria. The GWG 4 transducer malfunctioned between 3/12/2021 and 6/5/2021, and a new transducer was installed on 6/6/2021. Consequently, GWG 4 did not meet the success criteria with a measured maximum 14 consecutive days during the growing season. Monthly rainfall data in 2021 indicated higher than normal rainfall amounts in February and March. Lower than normal rainfall occurred in April, June, and September. Please refer to the CCPV Figures 3.0-3.2 in Appendix 2 for groundwater gage locations and Appendix 5 for groundwater hydrology summary data and plots. 1.2.5 Areas of Concern and Adaptive Management Plan Vegetation MY6 visual assessment reveal that more than 97% of the conservation easement is unaffected by invasive species populations. When present, these species include Japanese honeysuckle (Lonicera japonica), multiflora rose (Rosa multiflora), Chinese privet (Ligustrum sinense), Creeping primrose (Ludwigia peploides), Asian spiderwort (Murdannia keisak) and kudzu (Pueraria montana). Invasive species treatments occurred in March, June, and July 2021, and focused on small areas of multiflora rose, kudzu, and in -stream invasive exotic vegetation within UT1A and UT2. Populations of multiflora rose, creeping primrose, Asian spiderwort, and kudzu have been reduced by treatments to levels below the mapping threshold, therefore are not depicted on the CCPV Figures 3.0-3.2. MY6 visual assessments show that woody vegetation has become well established on at least 94% of the planted riparian areas. Previously identified areas of low stem vigor/height along the floodplains of UT1 Reach 2 and UT2 are still present but appear to be improving with desired volunteer species including river birch (Betula nigra), sycamore (Platanus occidentalis), black willow (Salix nigra), tag alder (Alnus serrulata), and cottonwood (Populus deltoides) naturally starting to develop and herbaceous vegetation filling in previously observed bare areas. In March 2021, a supplemental planting effort installed 135 bare roots, 85 tubling plants, and 135 livestakes within the potential wetland areas (0.661 acres) identified in the wetland addendum to increase woody stem density and species diversity. Woody transplants (river birch, box elder, tag alder, and black willow) from the adjacent project areas were also used where appropriate within the potential wetland areas.

In previous years, low flow and some vegetation within the channel had been noted along these reaches. A debris jam that was impeding some flow and causing aggradation within UT1A was removed in March 2021, and regular baseflow was observed throughout the rest of the year, as demonstrated by the stream gage plot for UT1A in Appendix 5. Similarly, minor aggradation previously noted along UT1 Reach 1 downstream of the wetland enhancement area, in the footprint of the old pond bed, has improved as woody vegetation along the banks has become established. Isolated areas of bank scour along UT1 (near station 124+25) were repaired in October 2021 by regrading and replanting the banks with live stakes and established transplanting vegetation from the floodplain. Previous bank repair areas along UT1 (near station 106+00 and 124+75) appear stable and effective. A few beaver dams were removed in summer 2021 throughout the lower portion of UT1 Reach 2. The period of prolonged inundation is demonstrated in the stream gage plot for UT1 in Appendix 5. Beaver dams were not observed during the fall 2021 site walk. Beavers remain present on the Site but the occurrence has decreased and negative effects have diminished. The now infrequent stream impoundments permit regular flow of tributaries (UT1A and UT2) into UT1, thus allowing floodplain vegetation to become established in previously inundated areas. Beaver activity will continue to be monitored and managed until closeout. Wetland Addendum As stated in section 1.2.4, three additional groundwater gages (GWG 13 — 15) were installed in February and March 2019 before the start of the MY4 growing season, for the purpose of providing groundwater data to document additional potential wetland areas. In September 2020, Wildlands staff determined that approximately 0.051 acres of the wetland re-establishment area, represented by GWG 8, is at risk of not meeting success criteria for wetland hydrology. A wetland addendum letter was submitted to DMS on October 6, 2020 to identify additional potential wetland areas that have been created by the project and formally request the inclusion of these created wetland areas for credit to offset those identified as at risk. Per the DMS credit release meeting in May 2021, a decision regarding the potential wetland areas will be made during the next IRT field review of the Site. Wildlands has incorporated the comments received by the IRT regarding the wetland addendum. As requested, Wildlands has supplementally planted the potential wetland areas with appropriate woody stems and established additional monitoring plots within these areas to determine if performance standards are being met. Please refer to Appendix 6 for the wetland addendum letter and subsequent IRT comments, CCPV Figures 3.0-3.2 in Appendix 2 for potential wetland locations, and Table 9d in Appendix 3 for vegetative monitoring plot results. ' a - Henry Fork Mitigation Site `4' Monitoring Year 6 Annual Report— FINAL 1-5 Conservation Easement There is an approved narrow footpath through the easement near vegetation plot 5 for the purpose of frisbee golf that Wildlands has allowed on a conditional basis and is set to discontinue by the time of closeout. This has continued to be monitored to ensure that it does not violate easement terms or threaten stream assets. The minor mowing encroachments that were observed in MY1 and MY2 along the floodplain of UT1 Reach 1 have been resolved. While there has been a stop to the encroachment issues, the Site boundary and prior problem areas will continue to be monitored for easement enforcement. Quarterly site visits will continue to be conducted to monitor and address areas of concern. If necessary, adaptive management will be implemented to improve the conditions of the Site. Please refer to Appendix 2 for CCPV Figures 3.0-3.2 for mapped areas of concern. 1.3 Monitoring Year 6 Summary Overall, the Site has met the required stream and vegetation success criteria for MY6. All restored and enhanced streams are stable and functioning as designed. All project streams recorded at least one bankfull event or greater in MY6. The bankfull performance standard was met for the Site in MY4. Vegetation within the planted riparian areas appear to be performing well with the majority of the acreage on track to meet the MY7 density requirement of 210 stems per acre. Thirteen of the fifteen groundwater monitoring gages installed on the Site met or exceeded the hydrologic success criteria for MY6. The MY6 visual assessments revealed a few areas of concern including pockets of invasive plant species, areas of low stem growth, and beaver activity. These areas will continue to be monitored and adaptive management will be performed as needed.

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. Vegetation monitoring protocols followed the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008).

General Figures and Tables ,ju50101090020 '050102010020 1 f The subject project site is an environmental restoration site of the 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. 61L r�rcli�7�jUY�iyUUk7i7 EllProject Location = Hydrologic Unit Code (14-digit) DMS Targeted Local Watershed 01140011 rOIrc &OPILOXO 7iUZG7 Directons to Site: The site is located in western Catawba County, NC, The site is southwest of the City of Hickory.

Wetland Addendum WILDLANDS ENGINEERING October 6, 2020 Mr. Matthew Reid NCDEQ Division of Mitigation Services 5 Ravenscroft Drive Suite 102 Asheville, NC 28801 Subject: Wetland Addendum Henry Fork Mitigation Site DMS Project No. 96303 DEQ Contract No. 005782 Catawba River Basin — HUC 03050103 Expanded Service Area Catawba County, North Carolina Dear Mr. Reid, Wildlands Engineering, Inc. (Wildlands) conducted a wetland assessment in 2020, Monitoring Year (MY) 5 of 7, to identify additional potential wetland areas on the Henry Fork Mitigation Site (Site) that have been created by this project. Additional supplemental data including a potential wetland area table, map figure, groundwater gage plots, photo log, and wetland data sheets have been included with this addendum letter. Background In anticipation of additional wetlands created on the Site after construction, section 8.2 (Wetland Mitigation Credits) of the Henry Fork Mitigation Plan states: "DMS reserves the right to request additional wetland credits created by the project. Wetland credits will be proposed based upon additional gauge data and/or wetland delineation." Therefore, in February and March 2019 (MY4), three groundwater gages were installed in locations adjacent to credited wetland areas to provide groundwater data to support the potential expansion of wetland areas on the Site. The purpose of delineating these extra areas is to offset any wetland credits that may be at risk of losing credit. Wildlands is not, however, seeking additional wetland credit above the original asset table amount. Wildlands defends and maintains a 7.2% (17 consecutive day) success criteria in the IRT approved Mitigation Plan but the USACE commented that a 8.5% (20 consecutive day) success criteria would be required. Wildlands updated the success criteria in the MYO report. The final performance standard established for wetland hydrology will be a free groundwater surface within 12 inches of the ground surface for 20 consecutive days (8.5%) of the 236 day growing season (March 20 through November 11) under typical precipitation conditions. Data Collection and Analysis As stated above, three additional groundwater gages (GWG 13 —15) were installed in February and March 2019 before the start of MY4 growing season, for the purpose of providing groundwater data to document additional wetland areas. On June 23, 2020, Wildlands personnel performed a Site investigation to identify additional potential wetland areas on the Site. Five areas (Wetlands AA through EE) were delineated and mapped using global positioning system (GPS) data collection and three wetland data points (DPI — 3) were collected. Please refer to the attached hydrologic data for groundwater gage plots and summary table of the success criteria for each gage on Site. Wetlands AA, BB, and CC are located south of Wetland N enhancement area. Before construction and as a former golf course, this area was identified as a ditch with a linear wetland that fed into intermittent stream channel UT2. During construction, the outlet of the ditch was plugged thus raising the groundwater level and creating conditions for anaerobic wetland processes to occur. GWG 15 was installed in MY4 to be representative of the low area and to document hydrologic conditions for the proposed wetland areas south of wetland N. For two consecutive years, GWG 15 has achieved the wetland hydrologic success criteria established for the Site. Wetland data point 1 (DPI) documents the hydrology, vegetation, and soil conditions representative of Wetlands AA, BB, and CC. Wetland DD is located in the footprint of a former golf course inline pond bed (pond 3) that was filled during construction. Before construction, UT1 flowed through pond 3 before making its way to the Henry Fork river. The restoration of UT1 realigned the stream channel and took pond 3 off line. The restored hydrology of UT1 has allowed for frequent overbank flooding of riparian wetland areas, thus expanding the hydrologic function into this area. GWG 1 was installed during the MYO baseline data collection and is in close proximity to Wetland DD. GWG 1 has achieved the wetland hydrologic success criteria for the Site in MY2 through MY5 thus far. Wetland data point 2 (DP2) documents the hydrology, vegetation, and soil conditions representative of Wetland DD. Wetland EE is located in and around the pre -construction footprint of UT1 near the previous UT1A confluence, adjacent to Wetlands J and K enhancement areas. The restoration of UT1A has increased the floodplain access from overbank flooding and resulted in a gain in wetland function well beyond the mapped wetland re-establishment area (Wetland 1). GWG 13 was installed in MY4 and has achieved wetland hydrologic success criteria for the past two years. Wetland data point 3 (DP3) was collected near GWG 13 and details the conditions of Wetland EE. Wetland Credits The combined area from Wetland AA through EE totals 0.661 acres. Pre -construction, these five areas were not wetlands and were not identified as such in the approved Jurisdictional Determination for the Site. Also, the additional wetland areas (AA — EE) were not identified as having hydric soils in the LSS soil report from the Mitigation Plan. Therefore, a creation credit ratio of 3:1 is proposed for all five wetland areas where a rise in groundwater elevations have created conditions necessary to support wetland conditions and promote wetland functions. In total, an additional 0.220 riparian wetland mitigation units (WMUs) are available to offset any wetland credits that may be determined to be at risk of losing credit. Please refer to the attached summary table of the additional wetland areas on the Site. Conclusion This wetland addendum summarizes the data collection and analysis of five proposed wetlands (Wetland AA — EE) that have been identified on the Site after construction was complete. Following DMS and IRT approval of this wetland addendum, Wildland's will document the additional wetland areas in this year's annual monitoring report. It will be stated in the report that these additional areas are only to be used as offset if any existing wetland credits are found to be at risk.

A detailed evaluation was conducted to characterize soils across the site, with a focus on identifying hydric soils. SITE LOCATION The site is located on an approximately 90-acre property, southwest of the intersection of Highway 321 and Interstate 40, at 2575 Mountain View Road (Parcel# 279108883819), in Hickory, NC. The evaluation area is situated in the floodplain of, and south of the Henry Fork River, north of the terminus of Mountain View Road. METHODOLOGY The hydric soil evaluation began with a cursory review of NRCS soils maps, recent aerial photos and a USGS topographic map for the area. The site analysis was performed on July 25, 2013. Soil auger borings were advanced throughout the study area. The hydric soil status at each location was noted, and is based upon the NRCS Field Indicators of Hydric Soils in the United States - A Guide for Identifying and Delineating Hydric Soils (Version 7.0, 2010). During the site evaluation, each soil boring was assigned to one of four different soil types or units: 0 Soil Unit 1 (S1) — Hydric, relatively undisturbed • Soil Unit 2 (S2) — Hydric soil that has been buried, with hydric indicators in the fill material 0 Soil Unit 3 (S3) — Hydric soil that has been buried. Fill material is non-hydric • Soil Unit 4 (S4) — Non-hydric soil (no evidence of buried hydric soil) Following the site investigation, field data were compiled to prepare the hydric soil map for the project. FINDINGS Evidence of anthropogenic site manipulation is abundant throughout the study area. One finds much evidence of ditching and/or channelization of streams across the site. Additionally, fill material has been placed over a majority of the floodplain area during past construction for the golf course. The soil beneath is generally undisturbed. The Soil Units are briefly discussed below and representative soil profile descriptions using the USDA - NRCS standard nomenclature are appended for hydric soil areas S1, S2 & S3. The attached "Henry River Project Hydric Soils Evaluation" map illustrates the approximate location of soil borings and soil map units across the site. Two, separate hydric soil areas were mapped during the evaluation. The western hydric soil area occupies approximately 1.49-acres, and consists only of S2 -3— September 9, 2013 Hydric Soil Evaluation Henry River Mitigation Site and S3 borings. The eastern hydric soil area occupies 3.03-acres, and consists of S1, S2 and S3 borings. Soil Unit 1 (S1) — Hydric Soil Soils in this area had no fill material and generally had typical diagnostic soil horizons. While several hydric soil indicators were present, indicator F3 was the most common. Indicator F3 - Depleted Matrix. A layer that has a depleted matrix with 60 percent or more chroma of 2 or less and that has a minimum thickness of either: a. 5 cm (2 inches) if the 5 cm is entirely within the upper 15 cm (6 inches) of the soil, or b. 15 cm (6 inches), starting within 25 cm (10 inches) of the soil surface. This soil typically had a silt loam textured surface horizon that ranged from 4 to 8 inches with oxidized rhizoshperes present. The subsurface textures were generally clay loam, grading to silty clay, with a matrix color of chroma 2 or less. Soil Unit 2 (S2) — Hydric Fill Over Hydric Soil Soil Unit 2 had fill material deposited during construction of the golf course. The soil beneath the fill was relatively undisturbed. Depth of fill was variable, but ranged from 6-to-12-inches. The buried soil had a loam textured surface horizon underlain by either loam, clay loam, or sandy clay loam subsurface horizons and met hydric indicator F3 Depleted Matrix. Here, the affects of hydrologic manipulation on the site are less pronounced and fill material has been on -site long enough to develop hydric indicators. While some of the fill material may have been hydric in origin (deposited from adjoining wetland or dredge from the ditches), most fill material was sourced from upland areas. There was evidence of active reduction and oxidation reactions in all borings. The soil either met indicator F3 Depleted Matrix or F6; Indicator F6 - Redox Dark Surface. A layer that is at least 10 cm (4 inches) thick, is entirely within the upper 30 cm (12 inches) of the mineral soil, and has: a. Matrix value of 3 or less and chroma of 1 or less and 2 percent or more distinct or prominent redox concentration occurring as soft masses or pore lining, or b. Matrix value of 3 or less and chroma of 2 or less and 5 percent or more distinct or prominent redox concentrations occurring as soft masses or pore linings. Soil Unit 3 (S3) — Non-Hydric Fill Over Hydric Soil Soil Unit 3 clearly had fill material deposited during construction of the golf course. The soil beneath the fill was relatively undisturbed. Depth of fill was quite variable, but ranges from 12-to- 26-inches. The buried soil had a silty clay loam surface horizon underlain by clay, silty clay or clay loam subsurface horizons. These areas met hydric indicator F3 - Depleted Matrix. While there was some evidence of recent reduction and oxidations reactions within some fill, it did not meet any of the hydric indicators. -4— September 9, 2013 Hydric Soil Evaluation Henry River Mitigation Site Soil Unit 4 (S4) — No Evidence of Buried Hydric Soil Most of Soil Unit 4 evidenced fill material, but in all cases neither the fill material nor the original soil met any hydric soil indicators within a depth reasonable for remediation. For example, some borings exhibited fill depths of greater than 36-inches, and were terminated. Since these areas contained mostly fill material without hydric soil indicators, a representative soil profile description was omitted. CONCLUSION This report presents information that may be used as reference for planning and design for the proposed work at the Henry River Mitigation site. Specifically, soil borings provide evidence of areas where hydric soils are either present or present below fill material. Soil units for each of these areas were delineated on the attached map. The site hydrology has been altered by ditching and/or channelization of streams and the addition of the fill material. Subsequently, opportunities exist for wetland restoration. These findings represent a professional opinion based on Hydric Soil Investigation and knowledge of the current regulations regarding wetland mitigation in North Carolina and national criteria for determining hydric soil. 4. �\ / = I (\\/); > ru .o \;2§gr 2 G LD g \ 2Ez=f /� . °. `\� k -§)/4 `� - 2 m m k k\// ■ _ _ Z � UUU0 U° -j 0 ° ' ] \--�\) \ ., ƒ 3 3 ._ o G U) - \ co { 2 \ 6 3 «� / \ $ CL 3 ° 3 .

The site is accessed off Mountain View Road (SR 1192) in Hickory, Catawba County, NC. The Catena Group, Inc. (Catena) was retained to perform a detailed soil investigation that would, in part, determine the depth of fill material that was previously observed during a preliminary soil and site. METHODOLOGY The field investigation was performed on April 29, 2014. Seventy-two (72) hand -turned auger borings were advanced throughout the study area on a seventy-five ft by seventy-five ft grid (Figure 1). Each soil boring was marked in the field with a red pin flag noting the boring number, soil unit number, and either depth of fill material or depth boring was terminated. Hydric soil status was based upon the NRCS Field Indicators of Hydric Soils in the Unities States - A Guide for Identifying and Delineating Hydric Soils (Version 7.0, 2010). RESULTS There is clear evidence of human manipulation throughout the study area. In addition to ditching and/or channelization of streams, fill material has been placed over the majority of the study area. Six Soil Units were created based on data collected from soil borings and are described below and summarized in Table 1. Table 2 lists the classification and fill depth when applicable for each soil boring (appended). Soil Unit 1. Soil Unit 1 had a typical surface diagnostic horizon that met hydric soil indicator F3. F3 Depleted Matrix. A layer that has a depleted matrix with 60 percent or more chroma of 2 or less and that has a minimum thickness of either: a. 5 cm (2 inches) if the 5 cm is entirely within the upper 15 cm (6 inches) of the soil, or 5 cm (6 inches), or b. 15 cm (6 inches), starting within 25 cm (10 inches) of the soil surface. Soil Unit 2. Soil Unit 2 consists of non-hydric soil that appeared to be undisturbed. Soil Unit 3. Soil Unit 3 clearly has overburden material deposited as a result of human manipulation. The soil material below the overburden was relatively undisturbed and met hydric indicator F3 Depleted Matrix. The overburden was classified as hydric and met hydric indicator F3 Depleted Matrix. Soil Unit 4. Soil Unit 4 clearly has overburden material deposited as a result of human manipulation. The soil material below the overburden was relatively undisturbed other than a compressed soil structure and a truncated profile, remnants of past surface manipulations. This material still appeared to be hydric and met indicator F3 Depleted Matrix. The overburden did not meet any hydric soil Henry Fork Hydric Soil Investigation May 13, 2014 Catena Job #4172 1 indicator. A typical soil profile for Soil Unit 4 is appended. Soil Unit 4 comprised the majority of the study site. Soil Unit 5. Soil Unit 5 clearly has overburden material deposited as a result of human manipulation. The overburden material and the soil beneath did not meet any hydric soil indicator. Soil Unit 6. Soil Unit 6 clear has overburden material deposited as a result of human manipulation. The surface of the overburden material currently meets hydric indicator F3 Depleted Matrix. The material below the surface did not currently meet any hydric soil indicator. Table 1.

Borings were placed into one of six Soil Units. The depth of fill material was noted at each boring when applicable. It is anticipated that Priority 1 stream restoration, combined with limited soil manipulation, has the potential to re- establish approximately 5.6 acres of wetlands (Figure 1). The findings presented herein represent Catena's professional opinion based on our Hydric Soil Investigation and knowledge of the current regulations regarding wetland mitigation in North Carolina and national criteria for determining hydric soil.

Please find our responses below in red text, and a copy of this email response attached in pdf for your files. We will require additional time to collect vegetation data and do planting to supplement these areas, but I'm hoping that based on this response we can get some feedback on our proposed approach to guide us in moving forward with this. Although our perceived wetland credit risk is low based on current data (see attached pdf), we understand that the IRT has viewed prior credit establishment on the site through a holistic lens based on the unique nature of this site. Furthermore, we understand that in order to agree to additional crediting on this site, this should include just effort to enhance ecological uplift and provide associated documentation. If you feel that the efforts proposed below are not commensurate with the credit being requested, we are amenable to revisit the ratio requested or the efforts proposed.

Per Section 332.8(o)(9) of the 2008 Mitigation Rule, this review followed the streamlined review process. All comments received during the review process are below. USACE Comments, Todd Tugwell and Kim Browning: The Corps requests vegetation data for these proposed wetland areas prior to approving their addition to the wetland assets.Some areas have woody stems (both planted and volunteer) while some do not. We propose to map areas of existing high and low density stem counts within the proposed wetlands, and to plant areas of low density during this dormant season at a rate of 600 stems/acre. We propose to set up 3 vegetation plots to track density and vigor in the proposed wetlands over the remaining monitoring term - we will do this in a way that includes representation of both existing and new stems. We also propose to visually monitor the success of new plantings. New plantings are proposed to consist of wetland and deer -tolerant livestakes which will limit diversity (and transplants from adjacent areas where available to supplement and diversify species). We have observations of low success with planting bareroot or potted trees that have already been rooted in a drier hydrologic regime and we have had significant vegetation setbacks and losses from deer on this site. If deemed acceptable, vegetation data will be provided prior to the credit release meeting in April, 2021. Only two of the five areas proposed have gauges in them. This is concerning because the IRT requested these gauges back in March 2016 if WEI thought the wetland boundaries were going to be different from the approved mitigation plan. We understand these were requested early on and have no response to counter this concern - gages13, 14, and 15 were installed as soon as we determined we desired to make this request. We feel that GWG1 is representative of Wetland DID and that GWG's 14 & 15 are representative of Wetlands AA, BB, and CC. Wetland EE appears to be relatively permanently impounded according to the gauge data, which raises concern whether this area may be too wet to support trees. The hydrologic regime of Wetland EE in 2019 was impacted by beaver impoundments - beaver were subsequently trapped and removed. Related to tree growth - it is true that the variation in topography in all of these wetlands influences the type of vegetation and habitat supported in each of these areas - some being old irrigation ponds or having ditch remnants that are emergent in character. Intermittent impoundment by beaver and riverine flooding have also influenced current vegetation. We proposed to attempt to establish woody vegetation in all of the wetlands, but recognize that some of the areas may not support this. We can accept that no credit may be offered for wetlands that do not support woody vegetation. Prior to approving this addendum we request veg data for the proposed areas, and we would like a map that shows the areas that are at-risk/not meeting success. Vegetation data will be collected and provided along with other data specified above. The map showing at -risk areas determined by gage analysis and wetland delineation is attached. EPA, Todd Bowers: At this time I have no specific comments on the proposed addendum for the site to provide 0.220 riparian wetland mitigation units to only be used if proposed wetlands at the mitigation site do not meet the thresholds or performance standards for success in the current mitigation plan. The created potential wetlands appear to be providing the appropriate function based on the groundwater gauge data (GWG 13 and 15) and the vigorous vegetation growth shown in the attached photos. As stated, the WMUs generated by this supplemental request would only be used to offset credits approved in the mitigation plan that are not granted due to failure to meet performance. WRC, Travis Wilson: Looking at the mapped locations as well at the photos it looks like the vegetation is comprised of emergent and pioneering species. All wetlands on this site were classified as Headwater forest. If these wetlands are going to be classified the same they should follow the same planting plan and vegetative success criteria. As discussed above, there are pockets of deeper water with prolonged inundation. We propose to plant woody species from the livestake planting plan this winter in areas that have not already revegetated with desired species (river birch, box elder, alders). Refer to proposed vegetative success monitoring in the response to Corps comments. Further, we have treatment of cattails visible in the photos scheduled for next year. We request that vegetation criteria be relaxed to the point of demonstrating successful establishment and progression of woody species in these areas rather than achieving full term criteria by the currently scheduled close-out date. DWR, Erin Davis: Are all of the proposed wetland creation areas outside of the original planted project area? I question whether they would meet the standard veg density performance standard. One of the areas is sweetgum dominated. Yes, most of the areas are outside of the planted area. We propose to perform the monitoring as stated above. There are dense riverbirch and alder thickets in some of the proposed wetland areas, but I don't believe that any areas are sweetgum monocultures. We have treated some such monocultures on the site within and adjacent to planted areas and will consider the same treatment in these creations areas where warranted. We do feel that with the difficulty of deer browsing on this site that establishment of canopy through pioneering species with an eye towards later forest succession may be better than no canopy. Please reach out if you have any questions.

Per Section 332.8(o)(9) of the 2008 Mitigation Rule, this review follows the streamlined review process, which requires an IRT review period of 15 calendar days from this email notification. Please provide any comments by 5 PM on the 15-day comment deadline shown below. Comments provided after the 15-day comment deadline (shown below) may not be considered. At the conclusion of this comment period, a copy of all comments will be provided to NCDMS and the NCIRT along with District Engineer's intent to approve or disapprove this AMP. Wildlands Engineering, Inc. (WEI) has prepared a Mitigation Plan Addendum for the Henry Fork Mitigation Site (DMS# 96306). WEI has identified five additional wetland areas that have developed following site construction. These five wetland areas were not identified in the approved Jurisdictional Determination (USACE) and they were not identified as having hydric soils in the LSS soils report from the IRT approved Mitigation Plan. As a result, WEI is proposing a creation credit ratio of 3:1 for the additional 0.661 acres for a total of 0.220 Riparian WMUs. WEI is not seeking additional wetland credit above the approved Mitigation Plan and the DMS credit ledger will not be updated. The purpose of proposing these additional areas for credit is to offset any wetland credits that may be at risk of losing credit at project closeout. These additional areas have been monitored since March 2019 (MY4) and will continue to be monitored through project closeout. Upon IRT review and approval of this wetland addendum, Wildland's will document the additional wetland areas in this year's annual monitoring report (MY5) and through project closeout. The site is currently in MY5 (2020) and is scheduled to close in 2023. Digital copies were uploaded to the IRT SharePoint page (10/6/2020) and DWR's Laser Fiche system (10/6/2020) for IRT review. A copy is also attached. 15-Day Comment Start: October 13, 2020 15-Day Comment Deadline: October 28, 2020 45-Day DE Decision: November 27, 2020 Project information is as follows: Henry Fork Mitigation Site DMS Project # 96306 Institution Date: 2/15/2014 RFP 16-005298 (Issued: 6/6/2013) Catawba River Basin Cataloging Unit 03050103 Expanded Service Area Catawba County, North Carolina USACE Action ID: SAW- 2014-00538 DW R#: 20140193 Proposed Mitigation Project Credits: 4,807.667 SMU (cool) 4.222 WMU (riparian) Full Delivery Provider: Wildlands Engineering Inc. — Contact: Jake McLean, jmclean@wildlandseng.com <mailto:jmclean@wildlandseng.com>, (828) 774-5547 NCDEQ- DMS Project Manager: Matthew Reid, matthew.reid@ncdenr.gov <mailto:matthew.reid@ncdenr.gov>, (828) 231-7912 The Mitigation Plan Addendum has been uploaded to the IRT/ NCDEQ Share Point Mitigation Plan Review page and can be accessed here: IRT SharePoint page: Blockedhttps://ncconnect.sharepoint.com/sites/IRT-DMS/Site Pages/Home.aspx HenryFrk_96306_M PAddend um_2020.pdf Blockedhttps://ncconnect.sharepoint.com/sites/IRT- DMS/IRT%20Upload%20Documents%20Here/Forms/Allltems.aspx?id=%2Fsites%2FIRT%2DDMS%2FIRT%20Upload%20D ocuments%20Here% 2FHenry%20Fork%20%2896306%29%2FHenryFrk%5F96306%5FMPAddendum%5F2020%2Epdf&par ent=%2Fsites%2FIRT% 2DDMS% 2FIRT%20Upload% 20Documents% 20Here%2FHenry%20Fork%20%2896306%29 <Blockedhttps://ncconnect.sharepoint.com/sites/IRT- DMS/IRT%20Upload%20Documents%20Here/Forms/Allltems.aspx?id=%2Fsites%2FIRT%2DDMS%2FIRT%20Upload%20D ocuments%20Here% 2FHenry%20Fork%20%2896306%29% 2FHenryFrk%5F96306%5FMPAddendum%5F2020%2Epdf&par ent=% 2Fsites% 2FIRT% 2DDMS% 2FIRT%20U pload % 20Documents% 20Here%2FHenry%20Fork%20%2896306%29> Please contact the Mitigation Office if you have questions.

It looks like you plan to replant livestakes, which might make it harder, but that is your choice; to earn full credit, this seems like a reasonable requirement. It also looked like there were a lot of pioneer species there already (like sweetgum and red maple) but it was hard to tell from the pictures. We'd like to review the veg data when it's available. Feel free to reach out if you have questions, Kim Kim Browning Mitigation Project Manager, Regulatory Division I U.S. Army Corps of Engineers -----Original Message ----- From: Jake McLean <jmclean@wildlandseng.com> Sent: Friday, December 18, 2020 8:10 AM To: Browning, Kimberly D CIV USARMY CESAW (USA) <Kimberly.D.Browning@usace.army.mil> Subject: [Non-DoD Source] RE: DMS Mitigation Plan Addendum Request: Henry Fork Stream and Wetland Mitigation Project/ SAW- 2014-00538/Catawba County Thanks Kim. We intended below to request that vigor be compared against year 1 & 2 standards ("successful... progression" of the proposed plantings). Is the IRT allowing for this to be the standard, or are you indicating that year 6 & 7 vigor standards must be met for full credit? Just wanting to clarify. From response: "We request that vegetation criteria be relaxed to the point of demonstrating successful establishment and progression of woody species in these areas rather than achieving full term criteria by the currently scheduled close-out date."
