(Wildlands) completed design and construction management on a design- bid-build project at the Glade Creek II Restoration Site (Site) for the North Carolina Division of Mitigation Services (DMS) in Alleghany County, NC.The project components included restoring and enhancing 2,579 linear feet(LF) and preserving 129 LF of perennial stream, restoring 0.16 acre of wetlands, and preserving 0.84 acre of existing wetland. Riparian buffers were also established by removing exotic invasive plants and installing a variety of native vegetation.The Site is expected to generate 2,166.467 stream mitigation units (SMUs) and 0.328 wetland mitigation units (WMUs)for the Glade Creek watershed (Table 1).The Site is located off US Highway 21 in the northern portion of Alleghany County, NC in the New River Basin, eight-digit Hydrologic Unit Code (HUC) 05050001 and the 14-digit HUC 05050001030020 (Figure 1).The project streams consist of one unnamed tributary, UT to Glade Creek, and two reaches along Glade Creek mainstem (Reach 1 and Reach 2) (Figure 2). Glade Creek flows into the Little River four miles northeast of the Site near Fox Trot Lane in the Town of Hooker, North Carolina. The Glade Creek II Restoration Project is located within a DMS Targeted Local Watershed (TLW) (Brush Creek, HUC 05050001030020), as documented within the 2009 River Basin Restoration Priorities (RBRP) for the New River Basin. Furthermore, the project site is located within Middle Glade Creek, a priority subwatershed for stream and wetland restoration (and habitat protection), as identified within 2006 Local Watershed Plan and Preliminary Project Atlas for Little River and Brush Creek. Primary stressors within the Brush Creek TLW and the Middle Glade Creek subwatershed include stream channelization, livestock access, degraded riparian buffers, and Christmas tree farming. Glade Creek is also classified as a trout water and the project will help improve trout habitat in the watershed. The project goals established in the mitigation plan addendum (Confluence, 2013) were completed with careful consideration of goals and objectives described in the RBRP and to address stressors identified in the LWP.The following project goals established include: • Improve water quality by repairing eroding stream banks and establishing riparian buffers; • Improve the community structure of the buffers; • Improve stream function and habitat by re-establishing stream-to-floodplain connections; • Restore long-term stability through the restoration of channel dimension, pattern and profile; • Improve in-stream habitat using in-stream structures;and • Remove exotic invasive plant species. The Site construction was completed between December 2015 and April 2016. Planting was completed in February 2016.The as-built survey was completed in January 2016 with Monitoring Year (MY) 0 beginning in May 2016. Annual monitoring has been completed for six years since as-built/construction. This report presents the Site's MY6 assessment and data as well as a closeout summary/analysis. Assessments completed over the past six monitoring years illustrate that the Site has met the success criteria as defined in the mitigation plan (Confluence, 2013)for vegetation, stream morphology, and stream and wetland hydrology,with the exception of a portion of UT to Glade where sediment deposition has resulted in a loss of stream function.The MY6 visual assessment revealed that invasive treatments have nearly eradicated many invasive species on the Site. In addition,wetland adaptive management activities and stream repairs that occurred in the Spring 2020 to alleviate previously identified areas of concern are performing well and have benefited the long-term ecological function of the Site. The as-built planted stem density averaged 742 stems per acre with the MY6 vegetation assessment resulting in an average planted stem density of 398 stems per acre.This exceeds the final success M Glade Creek II Restoration Project Monitoring Year 6 Annual/Closeout Report—FINAL criteria of 260 stems per acre and demonstrates that the Site has established a healthy riparian buffer. Stream morphology surveys along Glade Creek throughout the six years of monitoring demonstrate that the channel is functioning as designed and dimensions are indicative of stability.The extent of sediment deposition along UT to Glade Creek has been documented with the annual pebble counts, longitudinal and cross-section surveys. Bankfull events on all reaches have been documented in each post- construction monitoring year.Therefore, the success criteria of two bankfull flow events documented on restoration reaches and occurring in separate monitoring years was met for the project in MY2.The wetland groundwater gage has consistently met the success criteria for all six monitoring years, which demonstrates that the wetland hydrology has been restored on the Site. Included in Appendix 2 are photos from MVO and MY6 to illustrate bank stability and vegetation establishment over the course of six years of monitoring. DMS and DEQ-Stewardship have recently assessed the easement and boundary conditions, made minor upgrades to markings and posting, and DEQ stewardship has unofficially accepted the site for transfer.

Located in the Blue Ridge Belt (USGS,2016), Blue Ridge physiographic province, the project watershed includes primarily agricultural and forest land uses, with a drainage area of 8.0 square miles. The project stream reaches consist of Glade Creek and UT to Glade Creek(stream restoration).The project wetland areas consist of restoration and preservation (Wetlands A-D). Mitigation work within the Site included restoring and enhancing 2,579 LF and preserving 129 LF of perennial stream, restoring 0.16 acre of wetlands, and preserving 0.84 acre of existing wetland and proposes the generation of 2,166.467 SMUs and 0.328 WMUs.The stream and wetland areas were planted with native vegetation to improve habitat and protect water quality. Construction activities were completed by Carolina Environmental, Inc. in December 2015.Turner Land Surveying completed the as-built survey in January 2016. Storm repairs prior to end of the construction phase were completed in April 2016 and the repairs were judged to have not resulted in changes that would warrant a revised as-built survey. A 12.8-acre conservation easement was purchased in 2008 by the State of North Carolina and was recorded with Alleghany County Register of Deeds which will protect the project area in perpetuity. Appendix 1 includes detailed project activity, history, contact information, and watershed/site background information. Directions and a map of the Site are provided in Figure 1. Project components are illustrated in Figure 2 while Table 1 outlines the project component and mitigation credit information for the Site. 1.1 Project Goals and Objectives Prior to construction,the streams had been impacted by historic agricultural practices, silviculture and valley filling. In addition, there was widespread bank erosion, especially along the outside meander bends, and mid-channel deposition.The wetlands had been impacted by vegetation clearing, the establishment of exotic invasive plant species, and the burial of the hydric soils layer from historic valley fill.Table 4 in Appendix 1 and Tables 6a and 6b in Appendix 2 present the pre- and post-restoration conditions in detail. This mitigation site is intended to provide numerous ecological benefits within the New River Basin and addresses habitat degradation, which is the primary water quality stressor described in the New River RBRP (2009). While many of the benefits are limited to the immediate 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 were met by giving careful consideration to the goals and objectives described in the RBRP. The project specific goals of the Glade Creek II Restoration Site included the following: • Improve water quality by repairing eroding stream banks and establishing riparian buffers; • Improve the community structure of the buffers; • Improve stream function and habitat by re-establishing stream-to-floodplain connections; • Restore long-term stability through the restoration of channel dimension, pattern and profile; • Improve in-stream habitat using in-stream structures; and • Remove exotic invasive plant species. The project objectives have been defined as follows: Glade Creek II Restoration Project vivo Monitoring Year 6 Annual/Closeout Report—FINAL 1-1 • Restoration and enhancement of approximately 2,260 LF of Glade Creek; • Restoration of 319 LF of the UT to Glade Creek; • Preservation of 129 LF of UT to Glade Creek; • Restoration of 0.16 acre of wetland by improving hydrologic connections; • Preservation of 0.84 acre of existing jurisdictional wetland; and • Establishment of riparian buffers by removing exotic invasive plants and installing a variety of native vegetation. The stream and wetland performance criteria for the Site follow approved performance standards presented in the Glade Creek II Restoration Plan (Ward, 2008). Annual monitoring and semi-annual site visits were conducted to assess the condition of the finished project.The stream restoration and enhancement reaches (Glade Creek and UT to Glade Creek) of the project were assigned specific performance standards for stream morphology, hydrology, and vegetation. Wetland restoration areas were assigned specific performance standards for wetland hydrology and vegetation. The Glade Creek Stream Restoration Project was instituted prior to 7/28/2010; therefore,the Site was grandfathered in to be monitored for a minimum of five years post-construction. An additional year of monitoring (MY6) occured in 2021 to further assess repairs, with the Site anticipated to be presented for closeout in 2022. This report presents the Site's MY6 assessment and data as well as a closeout summary/analysis. 1.2 Monitoring Year 6 Data Assessment Annual monitoring was conducted between June and October 2021 to assess the condition of the project.The stream restoration success criteria for the Site follows the approved monitoring plan presented in the Glade Creek II Restoration Plan (Ward, 2008). 1.2.1 Vegetation Assessment A total of six vegetation monitoring plots were established during baseline monitoring within the project easement areas using a standard 10 by 10 meter or 5 by 20 meter plots. Please refer to the Current Condition Plan View(CCPV) Figure 3 in Appendix 2 for the vegetation monitoring plot locations.The final vegetation success criterion is the survival of 260 planted stems per acre in the riparian corridor along restored and enhanced reaches at the end of year five of the monitoring period. The MY6 vegetation survey was completed in September 2021, resulting in an average planted stem density of 398 stems per acre.The Site is exceeding the final density requirement of 260 planted stems, with all six plots (100%) individually exceeding this requirement. In addition,the number of volunteer woody stems have steadily increased each year with desired species including tag alder (Alnus serrulata), nine bark (Physocarpus opulifolius), red maple (Acer rubrum), and black willow(Salix nigra). Approximately 46%of the monitored stems have a health score (vigor) of 3 or greater, indicating that they are very likely to survive. Moreover, about 30%of the monitored stems have a vigor of 2 indicating that they have fair plant health with some damage present. Stems with a vigor of 1 that are unlikely to survive next year accounted for roughly 4%of the monitored stems.These lower vigor ratings were due to damage from deer and beaver herbivory, storm events, insects, suffocation from dense herbaceous cover, and other unknown factors.Tag alders that were planted from bare root at as-built accounted for 83%of the monitored stems found to be dead this year. However, the volunteer and transplant tag alders are numerous and thriving throughout the Site. Please refer to Appendix 2 for vegetation plot photographs and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern and Adaptive Management Activity The MY6 vegetation monitoring and visual assessments revealed that very few areas of concern persist on the Site. DMS contracted with a provider for invasive species treatment beginning in October 2019 Glade Creek II Restoration Project vivo Monitoring Year 6 Annual/Closeout Report—FINAL 1-2 and continuing throughout October 2021. Previously noted areas of invasive species were treated and observed to have very few resprouts with less than 0.1%of the easement acreage currently affected by invasive species. To increase woody stem densities in the wetland preservation area, supplemental planting occurred in April 2020. Visual assessments in MY6 revealed that planted woody stems in Wetland B appear healthy. Please refer to the CCPV Figure 3 in Appendix 2 for vegetation areas of concern. 1.2.3 Stream Assessment Morphological surveys for MY6 were conducted in June 2021; however, longitudinal profiles were only required for UT to Glade Creek.The longitudinal profile plot for UT to Glade Creek demonstrates the extent of aggradation and little change compared to MY5, which is further discussed below in Section 1.2.4. Cross-section survey results indicate that channel dimensions are stable and continuing to function on Glade Creek with minimal adjustments. As woody vegetation has become well established along the banks, floodplain deposition from recent bankfull events is evident in the riffle cross-sections along Glade Creek. As observed in previous MYs, cross-sections along UT to Glade Creek are representative of the significant sediment deposition and decreasing pool depths occurring throughout the reach. However,the surveyed riffle cross-section along UT to Glade (XS5) has maintained bed and bank elevations compared to MY5 with dimensions similar to MYO. Along Glade Creek, the reachwide pebble counts show coarser materials in the riffles and fines in the pools.The UT to Glade Creek reachwide channel materials resulted in a D50 of 0.3 mm (sand) during MY6.This fining of sediment materials observed in MY3 has continued through MY6 for UT to Glade Creek. Please refer to Appendix 4 for morphological tables and plots with annual overlays. 1.2.4 Stream Areas of Concern and Adaptive Management Activity As noted in previous MYs, UT to Glade Creek has experienced an increase in fine sediment each year after as-built. Large bankfull events along Glade Creek are depositing sediment along the floodplain and within the channel of UT to Glade Creek. In addition, land management activities upstream of the project are contributing excessive sedimentation on UT to Glade Creek. At the start of UT to Glade Creek Reach 2, the channel is actively braiding through Wetland D in the right floodplain of the original alignment. However downstream of Wetland D, willows and alders have become more established along the banks and have helped maintain channel form and function. DMS contracted with a provider to completed repairs along Glade Creek in April 2020.These repairs included installing a brush toe geolift and point bar regrading between stations 22+95 and 23+50, and stabilization of the hillslope between stations 24+25 and 24+75. Visual assessments in MY6 revealed that repairs appear to be stable and functioning as designed with livestakes and transplants becoming well established.A memo with as-built repair plans can be found in Appendix 6. Other small areas of scour that were not addressed by the repair remain along Glade Creek. However, woody vegetation is present along the banks in these areas causing them to be of relatively minor concern to the ecological integrity of the project. DMS also contracted with a provider to remove a beaver dam located on Glade Creek(near station 18+70) in October 2021. 1.2.5 Hydrology Assessment A bankfull event was documented for Glade Creek and UT to Glade Creek on June 7, 2021 based on crest gage measurements and recent wracklines found throughout the floodplain. In MY1 through MY6, there has been at least six bankfull events for each reach documented in separate years.The performance standard was met in MY2 with two bankfull flow events documented on restoration reaches and Glade Creek II Restoration Project vivo Monitoring Year 6 Annual/Closeout Report—FINAL 1-3 occurring in separate years during the five-year monitoring period. Refer to Appendix 5 for hydrologic data and graphs. 1.2.6 Wetland Assessment One groundwater monitoring gage (GWG 1)was established during baseline monitoring within the wetland restoration area using a logging hydrology pressure transducer.The gage was installed at an appropriate location so that the data collected will provide an indication of groundwater levels throughout the wetland restoration area.The target performance standard for wetland hydrology success consists of the presence of groundwater within 12 inches of the ground's surface for 21 consecutive days (12.5%) of the defined growing season for Alleghany County(April 26th to October 11th) under typical precipitation conditions.The Site does not contain a rainfall gage; therefore, the daily precipitation data was collected from closest NC CRONOS Station, Sparta 3.5 SSW. The GWG 1 recorded 169 consecutive days or 100%of the growing season; thereby exceeding the performance standard for MY6. Each time that the groundwater gage was downloaded in MY6, standing water was observed in the area surrounding the gage in Wetland D.This is corroborated by the groundwater gage data which plots water levels above the ground's surface for a majority of the growing season. Monthly rainfall data in 2021 indicated higher than normal rainfall amounts occurred during the month of August and lower than normal rainfall amounts occurred during the months of January and February. Please refer Figure 3 in Appendix 2 for the groundwater gage location, and Appendix 5 for hydrology data and plots. 1.2.7 Wetland Areas of Concern and Adaptive Management Activity In April 2020, DMS contracted with a provider to repair a headcut that had formed at the outflow of Wetland B where it meets Glade Creek Reach 2 (near station 22+75).The repairs included the installation of log sills for grade control at the wetland outflow. MY6 visual assessments reveal that the repair appears stable and has prevented the headcut from migrating into the wetland. As discussed in section 1.2.2, Wetland B had previously been noted to have poor woody stem growth and therefore supplemental planting occurred in April 2020 with appropriate wetland tree and shrub species. 1.3 Monitoring Year 6/Closeout Summary Assessments completed over the past six monitoring years illustrate that the Site has met the success criteria as defined in the mitigation plan (Confluence, 2013)for vegetation, stream morphology, and stream and wetland hydrology, with the exception of UT to Glade where sediment deposition has resulted in a loss of stream function.The MY6 visual assessment revealed that invasive treatments have nearly eradicated many invasive species on the Site. In addition,wetland adaptive management activities and stream repairs that occurred in the Spring 2020 to alleviate previously identified areas of concern are performing well and have benefited the long-term ecological function of the Site. The as-built planted stem density averaged 742 stems per acre with the MY6 vegetation assessment resulting in an average planted stem density of 398 stems per acre.This exceeds the final success criteria of 260 stems per acre and demonstrates that the Site has established a healthy riparian buffer. Stream morphology surveys along Glade Creek throughout the six years of monitoring demonstrate that the channel is functioning as designed and dimensions are indicative of stability.The extent of sediment deposition along UT to Glade Creek has been documented with the annual pebble counts, longitudinal and cross-section surveys. Bankfull events on all reaches have been documented in each post- construction monitoring year.Therefore, the success criteria of two bankfull flow events documented on restoration reaches and occurring in separate monitoring years was met for the project in MY2.The wetland groundwater gage has consistently met the success criteria for all six monitoring years, which demonstrates that the wetland hydrology has been restored on the Site. Included in Appendix 2 are Glade Creek II Restoration Project vivo Monitoring Year 6 Annual/Closeout Report—FINAL 1-4 photos from MVO and MY6 to illustrate bank stability and vegetation establishment over the course of six years of monitoring. DMS and DEQ-Stewardship have recently assessed the easement and boundary conditions, made minor upgrades to markings and posting, and DEQ stewardship has unofficially accepted the site for transfer. Repair area and site-wide comparative close out photos can be found in Appendix 7. Glade Creek II Restoration Project vivo Monitoring Year 6 Annual/Closeout Report—FINAL 1-5 Section 2: METHODOLOGY Geomorphic data was 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). Longitudinal and cross-sectional data were collected using a total station and were georeferenced. All Integrated Current Condition Plan View mapping was recorded using a Trimble handheld GPS with sub-meter accuracy and processed using was Pathfinder and ArcView. Crest gages were installed in surveyed riffle cross-sections and monitored semi-annually. Hydrology attainment installation and monitoring methods are in accordance with the USACE (2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey-NCEEP Level 2 Protocol (Lee et al., 2008).

During the 2019 IRT post-construction field review of the site, several areas were determined in need of repair. These areas included: 1. Wetland B: outlet headcut (approximate Glade Creek as-built stream station 22+75) and poor woody stem growth (0.74 acres) 2. Undercut brush mattress (approximate Glade Creek as-built stream station 22+95 to 23+50) 3. Left bank hillslope erosion (approximate Glade Creek as-built stream 24+25 to 24+75) Wildlands Engineering, Inc. (Wildlands) submitted a repair plan for the above areas to NC DMS on April 7, 2020 and received plan approval on April 14, 2020. Wildlands Construction mobilized to the site on April 15, 2020 and demobilized on April 17, 2020. Wildlands installed live stakes on April 22, 2020 and Bruton Natural Systems, Inc. planted tublings, containers, and bare root species on April 25, 2020. Changes made to the construction plans are detailed on the attached As-Built plan set. Planted woody species deviated from the plan based on nursery availability. Installed species by area and quantity are detailed below.
