(Wildlands) implemented a full delivery project at the Henry Fork Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DMS) to restore 3,087 linear feet (LF) of perennial streams and enhance 2,627 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 4,838 stream mitigation units (SMUs) and 4.22 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 UT113 (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 RBRP identifies a restoration goal for all streams within HUC 03050102 of removing conditions which cause sediment impairments, including mitigating stressors from stormwater runoff. The Henry Fork watershed was also identified in the 2005 North Carolina Wildlife Resource Commission's Wildlife Action Plan as a priority area, which calls for conservation and restoration of streams and riparian zones. In addition, the 2010 DWQ Catawba River Basin Plan indicated that the section of Henry Fork that drains to the project area is impaired for high turbidity, among other stressors. The intent of this project is to help meet the goals for the watershed outlined in the RBRP and provide numerous ecological benefits within the Catawba River Basin. 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 project goals established in the mitigation plan focused on permanent protection, reestablishing natural hydrology and vegetation, reducing water quality stressors and enhancing terrestrial and aquatic habitat. The decommissioning of the existing golf course, establishment of a permanent easement, and completion of construction and planting efforts have set a new trajectory that is intended to attain these goals, and monitoring assessments are being completed as proposed to measure established success criteria. The Site construction and as -built surveys were completed between November 2015 and March 2016. Monitoring Year 1 (MY1) assessments and site visits were completed between April and November, 2016 to assess the conditions of the project. Overall, the Site has met the required stream and vegetation success criteria for MY1. All restored and enhanced streams are stable and functioning as designed. Four automated and manual crest gages were installed on the Site to document bankfull events. One bankfull event was recorded on UT1A since construction completion. Vegetation assessment indicates that overall average stem density for the Site is 599 stems per acre, and is therefore on track to meet the MY3 requirement of 320 stems per acre. Wetland re-establishment and rehabilitation areas are meeting or exceeding hydrology conditions at the adjacent reference gage in this drought year. Of the 7 groundwater monitoring gages installed within the wetland rehabilitation and re-establishment zones, 3 Henry Fork Mitigation Site Monitoring Year 1 Annual Report — FINAL met the success criteria (water table within 12 inches of the ground surface for 8.5% of the growing season consecutively). While not all gages at the Site met the wetland hydrology criteria, monthly rainfall was below average for the majority of the growing season. It is anticipated that these wetland areas will continue to recharge and meet hydrologic success criteria in the upcoming monitoring years as precipitation normalizes.

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 UT113. Stream restoration reaches included UT1 (Reach 1 and 2) and UT113, together comprising 3,087 linear feet (LF) of perennial stream channel. Stream enhancement reaches included UT1A and UT2, together totaling 2,627 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 4,838 stream mitigation units (SMUs) and 4.22 wetland mitigation units (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; Henry Fork Mitigation Site Monitoring Year 1 Annual Report — FINAL 1-1 • Improve instream habitat; and • 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 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 1 Data Assessment Annual monitoring and quarterly site visits were conducted during MY1 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 Morphological surveys for the MY1 were conducted in September 2016. All streams within the site are stable. In general, riffle cross sections show little to no change in the bankfull area, maximum depth ratio, or width -to -depth ratio. Slight decreases in maximum bankfull depth were observed in pool cross sections 2, 3, 6, 11, and 13, which is common in newly constructed pools. Minor fluctuations in bed elevations are expected especially in systems dominated by fine grained (sand/silt) particles. Surveyed riffle cross sections fell within the parameters defined for channels of the appropriate Rosgen (Rosgen, 1994 & 1996) stream type. Pebble counts in UT1 Reach 1 and UT113 indicate maintenance of coarser materials in Henry Fork Mitigation Site Monitoring Year 1 Annual Report — FINAL 1-2 the riffle features and finer particles in the pool features. Refer to Appendix 2 forth e visual stability assessment table, CCPV map, and reference photographs. Refer to Appendix 4 for the morphological data and plots. Beaver activity was observed at the downstream end of the project site between Stations 123+00 and 127+00 of UTI Reach 2. Multiple beaver dams were removed between May and September 2016. The short-term backwater associated with the dams was primarily contained within the active channel and isn't impacting stream stability. 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. One bankfull event was recorded on UT1A during the MY1 data collection. No automated stream gage data will be presented in Year 1, however, manual crest gage readings are reported. Issues with automated stream gages were identified during data processing. Upon field investigation and further data review, it was found that the inaccuracies in the automated stream gage data were a result of the in -stream pressure gages and barotroll gage recording at different times and intervals. The barotroll records the atmospheric pressure and is used to correct the reading on the stream pressure gages. The in -stream pressure transducers and barotroll have been reprogrammed to record at the same time and interval (every 15 minutes) going forward to provide accurate stage height data. Refer to Appendix 5 for hydrology summary data and plots. In addition, 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. While gages were deployed, and data was collected for MY1, no automated gage data will be presented in this report due to inaccuracies discussed in the previous paragraph. In addition, while water was frequently observed during dry weather in the intermittent channels, rainfall for the year was far below typical norms. Due to issues that arose during data processing, we revisited all of our gage setups, on both perennial and intermittent tributaries, to reprogram and ensure that all gages are functioning properly and accurately correlated to benchmarks. In addition, we may consider alternate or additional approaches to demonstrate intermittent flow such as timed cameras if our efforts to reprogram the gages is still not effective on the intermittent streams. 1.2.3 Vegetative Assessment Planted woody vegetation is being monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008). A total of 15 vegetation plots were established during the baseline monitoring within the project easement area. All of the plots were installed using a standard 10 meter by 10 meter plot. The final vegetative success criteria will be the survival of 210 planted stems per acre in the planted riparian and wetland corridor at the end of the required monitoring period (MY7). 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 the third monitoring year (MY3) and at least 260 stems per acre at the end of the fifth monitoring year (MY5). Planted vegetation must average 10 feet in height in each plot at the end of the seventh year of monitoring. If this performance standard is met by MY5 and stem density is trending towards success (i.e., no less than 260 five year old stems/acre), monitoring of vegetation on the Site may be terminated provided written approval is provided by the United States Army Corps of Engineers in consultation with the NC Interagency Review Team. Henry Fork Mitigation Site Monitoring Year 1 Annual Report — FINAL 1-3 The MY1 vegetative survey was completed in September 2016. The 2016 vegetation monitoring resulted in an average stem density of 599 stems per acre, which is greater than the interim requirement of 320 stems/acre required at MY3, but approximately 9% less than the baseline density recorded at MYO, 656 stems/acre in January 2016. There is an average of 15 stems per plot as compared to 16 stems per plot in MYO. All 15 of the plots are on track to meet the success criteria required for MY7 (Table 9, Appendix 3). Refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables. 1.2.4 Vegetation Areas of Concern Invasive species including Chinese privet (Ligustrum sinense), Japanese honeysuckle (Lonicera japonica), and multiflora rose (Rosa multiflora) were present along the northern edge and southern end of the Site. These areas were treated during MY1 and will be monitored in future years. These species are not impacting survival rates of planted stems. Minor encroachments of the easement occurred along the eastern edge of UT1 Reach 1, in the vicinity of the existing offsite clubhouse. Encroachments included minor mowing infringement and a small area of burning. The adjacent landowner has been notified that the activities are in violation of the easement and the burned area will be reseeded, along with other areas that have sparse herbaceous vegetation, in Spring of 2017. Refer to Appendix 2 for the vegetation condition assessment table and Integrated Current Condition Plan View (CCPV). 1.2.5 Wetland Assessment Seven groundwater hydrology gages (GWG's) were established during the baseline monitoring within the wetland rehabilitation and re-establishment zones (GWG's 1— 4 and 6 — 8). All gages were installed at appropriate locations so that the data collected will provide an indication of groundwater levels throughout the Site. Two additional gages (GWG 5 and 9) were installed for exploratory purposes in areas not proposed for restoration or enhancement activities; as such, GWG 5 and 9 are not included in gage performance evaluation. An additional gage was established in an adjacent reference wetland and is being utilized to compare 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) and a rain gage were also installed on the Site. All monitoring gages were downloaded on a quarterly basis and maintained on an as needed basis. Historical growing season data is not available for Catawba County therefore the growing season from Burke County, which runs from March 20th to November 11th (236 days), will be used for hydrologic success. The final performance standard for wetland hydrology will be a free groundwater surface within 12 inches of the ground surface for 20 consecutive days (8.5 percent) of the defined 236 -day growing season under typical precipitation conditions. Of the seven groundwater monitoring gages within rehabilitation and re-establishment zones (GWG 1- 4 and 6 — 8), 3 met the success criteria for MY1. Of the gages that met, the measured hydroperiod ranged from 12.3% to 100% of the growing season. Below normal precipitation was recorded for the majority of the growing season. Although several on-site gages did not meet success criteria in MY1, they generally exhibited groundwater levels and/or recharge greater than the adjacent reference gage. With normal annual rainfall in subsequent monitoring years, groundwater recharge is expected and all gages are expected to meet success criteria in the future. Refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology summary data and plots. Henry Fork Mitigation Site Monitoring Year 1 Annual Report— FINAL 1-4 1.3 Monitoring Year 1 Summary The streams within the Site are stable and functioning as designed. The average stem density for the Site is on track to meeting the MY7 success criteria and all individual vegetation plots meet the MY1 success criteria as noted in CCPV. Of the 7 groundwater gages, 3 met the success criteria for MY1. In general, gages within the wetland re-establishment and rehabilitation areas are meeting or exceeding hydrology conditions at the adjacent reference gage. It is anticipated that gages will meet hydrologic success criteria in the upcoming monitoring years as precipitation normalizes. One bankfull event was documented on UT1A during MY1. 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 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 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).
