(Wildlands) has reviewed the Division of Mitigation Services (DMS) comments from the Draft Monitoring Year 4 report for the Henry Fork Mitigation Project. The following Wildlands responses to DMS’s report comments are noted in italics lettering. DMS comment; Please add callout on CCPV for location of bank repair on UT1. Wildlands response; A callout has been added to CCPV Figure 3.2 to note the location of the bank repair on UT1. DMS comment; On Page 1-4, the report mentions minor bank repairs are planned on UT1 Reach 2 near 102+75. This stationing does not correspond to UT1 Reach 2 according to the CCPV. Please update accordingly. Wildlands response; The stationing has been corrected in the report text. DMS comment; Page 1-5 describes a narrow footpath through the easement near vegetation plot 5 for the purpose of the frisbee golf course. During the on-site meeting held January 16, 2019 with Wildlands, IRT and DMS, the IRT expressed concern with the trail and indicated it would need to discontinue by the time of closeout. Wildlands indicated they would communicate this to the adjacent land owner. Meeting minutes are attached. Wildlands response; Text has been added to this paragraph to be consistent with the January 16, 2019 meeting minutes. DMS comment; For clarity, consider adding the consecutive day number for each gage on the groundwater gage plots instead of using the currently shown 20 day bar. The gage 8 plot shows 19 days which corresponds to the consecutive days for that gage. All the other gages use the 20 day bar. Wildlands Engineering, Inc.  phone 704-332-7754  fax 704-332-3306  1430 S. Mint Street, # 104  Charlotte, NC 28203 The 20 day bar adds some confusion to the plots without a description of what it corresponds too (8.5% of the growing season). Wildlands response; For clarity, the number of consecutive days is now shown instead of the 20 day bar on all groundwater gage plots. Digital Files Review DMS comment; Wetland 1, 2, B, G, N, and R features in the DMS geodatabase do not match what is reported in the monitoring report asset table. Please provide DMS with features for these wetlands that accurately characterize the creditable assets. Wildlands response; A new shapefile called “ALL_Wetlands” has been added to the electronic support files that correctly matches the creditable assets. DMS comment; DMS cannot open the "Henry Fork In-Stream Flow Gage with..." file. Please confirm that the file cannot be opened, and if it cannot, provide a new file. Wildlands response; Yes, Wildlands is able to open the file that was provided to DMS in the electronic support files. Please let us know if there continues to be an issue with opening the file. Enclosed please find two (2) hard copies and one (1) electronic copy on CD of the Final Monitoring Report. Please contact me at 704-332-7754 x101 if you have any questions. Sincerely, Andrea S. Eckardt, Ecological Assessment Team Leader aeckardt@wildlandseng.com Henry Fork Mitigation Site Monitoring Year 4 Annual Report – FINAL i 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 4.221 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 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; and • Correct modifications to streams, wetlands and buffers; • Improving and re-establishing hydrology and function of previously cleared wetlands; • Reducing current erosion and sedimentation; • Reduce nutrient inputs to streams and wetlands, and to 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) 4 assessments and site visits were completed between February and November 2019. Per Inter-agency Review Team (IRT) guidelines, detailed monitoring and analysis of vegetation and channel cross-sectional dimensions were omitted during MY4. Visual observations, substrate data, 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 MY4. All restored and enhanced streams are stable and functioning as designed. All project streams recorded at least one bankfull event or greater in MY4; therefore, the bankfull performance standard has been met for the Site. Vegetation appears to be performing adequately to attain the MY5 density requirement of 260 stems per acre. Fourteen of the fifteen groundwater monitoring gages installed on the Site met or exceeded the hydrologic success criteria for MY4. The MY4 visual assessment revealed a few areas of concern including pockets of invasive plant species, areas of low stem vigor, isolated areas of bank scour, and beaver activity which 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 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 for restoration reaches, however the tributaries are intermittent, and as such were credited as enhancement. The riparian areas of the tributaries, as well as a 100 foot-wide buffer of the 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 SMUs and 4.221 WMUs. Annual monitoring will be conducted for seven years with the close-out 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 This Site is intended to provide numerous ecological benefits within the Catawba River Basin. 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; • Improving and re-establishing hydrology and function of previously cleared wetlands; • Reducing current erosion and sedimentation; • Reduce nutrient inputs to streams and wetlands, and to downstream water bodies; • Improve instream habitat; and • Provide and improve terrestrial habitat, and native floodplain forest. The project goals were addressed through the following project objectives: Henry Fork Mitigation Site Monitoring Year 4 Annual Report – FINAL 1-2 • 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 also 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; • A native vegetation community will be planted 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, connectivity of habitat within Site and to adjoining natural areas along the river corridor. 1.2 Monitoring Year 4 Data Assessment Annual monitoring was conducted during MY4 (February to November 2019) 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 MY4 is a reduced monitoring year that does not require morphological surveys; therefore no cross- sectional survey was performed this year. In general, MY4 pebble counts in UT1 and UT1B indicate maintenance of coarser material in the riffle features and finer particles in the pool features. Refer to Appendix 2 for the visual stability assessment tables, Current Conditions Plan View (CCPV) Figures 3.0- 3.2, and reference photographs and Appendix 4 for pebble count plots. 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. During MY4, all stream reaches recorded at least one bankfull event. Multiple bankfull events had been recorded in previous monitoring years on all reaches; therefore, the performance criteria has been met for the Site. Henry Fork Mitigation Site Monitoring Year 4 Annual Report – FINAL 1-3 In addition to monitoring bankfull events, intermittent streams must be monitored to demonstrate that stream flow regimes are sufficient to establish an Ordinary High Water Mark, specifically a minimum of 30 consecutive days of flow during periods of normal rainfall. The stream gages indicated each stream recorded between 150-300 days of consecutive flow. Presence of baseflow was observed in UT1, UT1A, and UT1B during each site visit. UT2 was observed with baseflow during all site visits except for the period with lower than normal amounts of rainfall from September to October. These observations confirm data recorded by the stream gages. Refer to Appendix 5 for hydrology summary data and plots. 1.2.3 Vegetative Assessment MY4 is a reduced monitoring year that does not require detailed vegetation inventory and analysis; therefore no vegetation plot monitoring was performed this year. Visual assessment in MY4 indicate that planted stems are surviving, and the Site should be on track to meet the MY5 density requirement of 260 stems per acre. 1.2.4 Wetland Assessment In total, there are fifteen GWGs currently on the Site. Seven groundwater hydrology gages (GWGs) were established during the baseline monitoring within the wetland rehabilitation and re-establishment zones (GWGs 1 – 4 and 6 – 8). Two additional gages (GWG 5 and 9) were installed within the wetland re- establishment areas during 2017 (MY2) in order to further assess wetland performance. During the initial GWG installation, GWG 3 was installed in a seep where hydrology was much stronger than the surrounded area; therefore, GWG 3 was relocated in January 2017 (MY2) to an area that was more representative of the surrounding wetlands. The transducer for GWG 5 was replaced at the beginning of MY4 due to abnormal data in MY3 and to ensure accurate water level data is being reported. In February and March 2019 (MY4), six additional GWG were added to the Site. Three 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. Following construction, gages were distributed so that 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 and is being utilized to compare with the hydrologic response within the restored wetland areas at the Site. A barotroll logger (to measure barometric pressure used in the calculations of groundwater levels with gage transducer data) was installed on the Site. The rainfall data is collected from an existing NC CRONOS station (Hickory 4.8 SW, NC). All monitoring gages were downloaded on a quarterly basis and maintained on an as needed basis. A soil temperature gage was also installed on Site in October 2016. Wildlands is using the soil temperature probe data to confirm the dates defined in the WETS table for Burke County, NC. The WETS growing season is not available for Catawba County; however, a growing season is defined for historic weather data collected at the Hickory Regional Airport in Burke County, which is approximately 3 miles as the crow flies from the Site. The growing season from Burke County, which runs from March 20th to November 11th (236 days), is being used for hydrologic success. 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. Of the fifteen GWGs, fourteen met the success criteria for MY4. Of the gages that met, the percentage consecutive days of the growing season ranged from 15% to 100% of the growing season. While GWG 8 was the only gage that did not meet criteria, the measured maximum consecutive days was short by Henry Fork Mitigation Site Monitoring Year 4 Annual Report – FINAL 1-4 only one day. GWGs 5, 10, and 13 achieved the success criteria for 100% of the growing season with plots showing similar hydroperiods indicating comparable groundwater hydrology in those areas. The remainder of the GWGs follow the hydroperiod of the reference gage. Refer to the CCPV Figures 3.0-3.2 in Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology summary data and plots. 1.2.5 Areas of Concern and Adaptive Management Plan Vegetation In MY4, minor areas of invasive plant populations are found within the conservation easement. These species include: Japanese honeysuckle (Lonicera japonica), multiflora rose (Rosa multiflora), Chinese privet (Ligustrum sinense), Creeping primrose (Ludwigia peploides), and Asian spiderwort (Murdannia keisak). Areas of dense sweet gum (Liquidambar styraciflua) monocultures were also identified and treated within the planted areas in the Site. Wildlands contracted with a provider for invasive species/sweet gum treatment that occurred in November 2019. Visual assessments in MY4 continued to reveal areas with low stem vigor/height and poorer herbaceous cover on the lower portion of the Site (UT2 and UT1 Reach 2 floodplains). Though the herbaceous cover in these areas remains less established in comparison to the rest of the Site, it has improved over time from previous monitoring years. The floodplains of UT2 and UT1 Reach 2 were addressed in the fall of MY4 with an additional seeding and amendment application. These areas will continue to be monitored and Wildlands will implement further remedial action such as supplemental planting if necessary. Streams Following a large storm event in June 2019, isolated areas of bank scour were noted along UT1. In August 2019, minor repairs were performed on UT1 Reach 1 on the pool near station 106+00 consisting of regrading the outside meander bend and replanting the banks with established vegetation transplanted from the floodplain. Additional minor bank repairs, in part related to beaver activity, are planned for an area of bank scour on UT1 Reach 2 near station 124+75 and to be completed in the winter of 2019/2020. Continuing in MY4, low flow (water present, but low velocity) in UT1A and UT2 was observed with some vegetation within the channel. A defined baseflow channel is still present and as woody vegetation becomes more established and shades out in-stream vegetation, the baseflow channel is expected to become less vegetated. In November 2019, additional live-stakes were planted to supplement the woody vegetation along the banks where needed on UT1A and UT2 in order to improve stream shading. During MY2, a portion of UT1 Reach 1 was found to be flowing subsurface and surface repair and plugging of this area was completed in December 2017 in order to address the issue. The repair has remained effective throughout MY4. Several beaver dams have been removed in MY4 throughout the lower portion of UT1 Reach 2. The beaver activity has been limited to the lower portion of the project and off site before the tributary reaches Henry Fork. Beaver activity will continue to be monitored and managed throughout closeout. Wetlands In previous monitoring years, wetland hydrology had been weak in the wetland rehabilitation areas upslope of UT1 Reach 2 (GWGs 2 – 3) and at the head of UT2 (GWG 8). As discussed in section 1.2.4, all GWGs except for GWG 8 met or exceeded the success criteria indicating that groundwater levels have continued to recharge in MY4, bolstered by strong winter rainfall totals, as well as above average growing season rainfall. Three of the additional gages (GWGs 10 – 12) were installed at the beginning of MY4 ensure adequate representation of the hydrology in the wetland re-establishment area upslope of Henry Fork Mitigation Site Monitoring Year 4 Annual Report – FINAL 1-5 UT1 Reach 2. The three remaining gages (GWGs 13 – 15) added in MY4 were installed adjacent to wetland enhancement areas to provide hydrology data to support the potential expansion of these areas to offset any loss of wetland re-establishment areas where GWGs are not meeting success criteria. 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 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 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 any areas of concern. If necessary, future adaptive management will be implemented to improve herbaceous cover, treat and control invasive plants, and address hydrology issues. Please refer to Appendix 2 for CCPV Figures 3.0- 3.2. 1.3 Monitoring Year 4 Summary Overall, the Site has met the required stream and vegetation success criteria for MY4. All restored and enhanced streams are stable and functioning as designed. All project streams recorded at least one bankfull event or greater in MY4; therefore, the bankfull performance standard has been met for the Site. Vegetation appears to be performing adequately to attain the MY5 density requirement of 260 stems per acre. Fourteen of the fifteen groundwater monitoring gages installed on the Site met or exceeded the hydrologic success criteria for MY4. The MY4 visual assessment revealed a few areas of concern including pockets of invasive plant species, areas of low stem vigor, isolated areas of bank scour, and beaver activity which will continue to be monitored and adaptive management will be performed as needed. Summary information and data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Mitigation Plan documents available on DMS’s website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Henry Fork Mitigation Site Monitoring Year 4 Annual Report – FINAL 2-1 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 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).
