(Wildlands) has reviewed the Division of Mitigation Services (DMS) comments from the Draft Monitoring Year 4 report for the Glade Creek II Mitigation Project. The following Wildlands responses to DMS’s report comments are noted in italics lettering. DMS comment; 1.2.6 – Wetland Assessment – In light of the wetland gauge data showing success for 100% of the growing season (169 consecutive days), can Wildlands describe the general appearance of the wetland with regard to standing water (or lack of)? Wildlands response; Each time that the groundwater gage was downloaded in MY4, 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. Text has been added to section 1.2.6. DMS comment; 1.2.7 – Wetland Areas of Concern – During a recent site visit with the IRT, it was questioned whether or not the Wetland A pocket preservation wetlands along the preservation section of UT to Glade still existed on the site. In the absence of another delineation, does Wildlands feel there are still wetlands visually apparent where Wetland A is shown on the map? If not, it should be noted as a possible change in site conditions in that area since the delineation was performed. Wildlands response; Absence of a formal delineation, Wetland A visually appears to exist as small terraces adjacent to the channel of UT to Glade Creek with hydrology influenced by the tributary’s water table. Netted chain fern (Woodwardia aereolata) was the predominate herbaceous plant observed at the time of the most recent site walk (December 2019) which is a facultative wetland (FACW) plant. DMS comment; 1.2.7 – Wetland Areas of Concern – It was noted during the recent IRT site visit that, in the wetland restoration area (Wetland D), that woody vegetation that was described in the mitigation plan and part of the construction planting plans, seemed lacking and not meeting performance standards. Since there is no plot in wetland D, there is no data. However, can Wildlands offer a visual Wildlands Engineering, Inc.  phone 704-332-7754  fax 704-332-3306  1430 S. Mint Street, # 104  Charlotte, NC 28203 assessment of the percentage of wetland lacking planned vegetation, versus the total wetland area on the site? Wildlands response; Based on a visual assessment, the area lacking woody vegetation corresponds with the area normally observed to have standing water in Wetland D. This accounts for approximately 6 percent of the total wetland area on the Site (roughly 0.05 acre/0.84 acre). Text has been added to section 1.2.7. DMS comment; Table 3 project contact table – Please delete entries where there is no contractor listed. Wildlands response; Table 3 has been updated.

Sincerely, Kirsten Y. Gimbert Project Manager kgimbert@wildlandseng.com Glade Creek II Restoration Project Monitoring Year 4 Annual Report – FINAL i EXECUTIVE SUMMARY Wildlands Engineering, Inc. (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 0.33 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 land adjacent to the streams and wetlands is primarily maintained for forestry production of White Pine trees. 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. Storm repairs were completed prior to the end of the construction phase in April 2016. MY4 activities occurred between March and October 2019. The MY4 morphological surveys and visual assessments indicate that the majority of Glade Creek appears stable and functioning as designed; however, sediment deposition has caused a loss of channel function along a portion of UT to Glade Creek. The MY4 vegetation assessment resulted in an average planted stem density of 519 stems per acre and is exceeding the final success criterion of 260 stems per acre. In addition, five out of six plots individually met this requirement. The Site’s groundwater gage met the performance standard for MY4. The bankfull performance standard was met for the project in MY2. The MY4 visual assessment revealed a few areas of concern including pockets of invasive species present on the Site and isolated areas of bank scour. The continual maintenance of these areas of concern would benefit the Site long term and decrease additional impacts to the project.

The Site is located in the New River Basin, eight-digit Hydrologic Unit Code (HUC) 05050001 and the 14-digit HUC 05050001030020 (Figure 1). Located in the Blue Ridge Belt (USGS,2016), Blue Ridge physiographic province, the project watershed includes primarily agricultural and forest land uses. The drainage area for the project site is 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 linear feet (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 0.33 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. The conservation easement protects 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 and project components are illustrated for the Site in Figure 2. Please refer to the Project Component Map (Figure 2) for the stream and wetland features and to Table 1 for 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 Glade Creek II Restoration Project Monitoring Year 4 Annual Report – FINAL 1-2 • Remove exotic invasive plant species. The project objectives have been defined as follows: • 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 will be 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 will be monitored for five years post-construction. 1.2 Monitoring Year 4 Data Assessment Annual monitoring was conducted between March and October 2019 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 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 MY4 vegetation survey was completed in September 2019, resulting in an average planted stem density of 519 stems per acre. The Site is on track to meet the MY5 density requirement of 260 planted stems per acre, with 5 of the 6 plots (83%) individually meeting this requirement. Vegetation plot 1 is not currently meeting the final requirement with a density of 243 planted stems per acre. Though with the inclusion of desirable volunteers in the stem density counts, plot 1 would be exceeding the requirement. Approximately 81% of the planted stems have a health score (vigor) of 3 or greater. However, about 13% of the stems have a vigor of 2 or less, and 6% of the stems are missing. The poor health is a result of suffocation from dense herbaceous cover, insects, dry conditions, or other unknown factors. Please refer to Appendix 2 for vegetation plot photographs and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern The MY4 vegetation monitoring and visual assessment revealed few vegetation areas of concern. Areas noted at the beginning of the monitoring year with poor herbaceous cover and sandy deposition on the floodplain of Glade Creek have recovered with vegetation becoming naturally well established. Small pockets of invasive plant populations were identified in MY4 throughout the Site. Species included: Oriental bittersweet (Celastrus orbiculatus), multiflora rose (Rosa multiflora), barberry (Berberis Glade Creek II Restoration Project Monitoring Year 4 Annual Report – FINAL 1-3 thunbergii), and Kudzu (Pueraria montana). DMS has contracted with a provider for invasive species treatment beginning in October 2019 and continuing through 2020. Please refer to the current condition plan view (CCPV) Figure 3 in Appendix 2 for vegetation areas of concern and Appendix 6 for invasive species treatment logs. 1.2.3 Stream Assessment Morphological surveys for MY4 were conducted in April and May 2019. Along Glade Creek, the surveyed longitudinal profile illustrates that bedform features are maintaining vertical stability for the majority of the surveyed reaches. Profile dimensions for Glade Creek are showing little change between MY3 and MY4. The longitudinal profile plot for UT to Glade Creek demonstrates the extent of aggradation that has altered the channel profile, which is further discussed below in Section 1.2.4. Please refer to Appendix 4 for longitudinal profiles with annual overlays and Table 13a-b for stream reach data summaries. Cross-section survey results indicate that channel dimensions are stable and functioning as designed on Glade Creek with minimal adjustments. Some deposition was noted on the banks of Glade Creek thus raising the low bank elevation and slightly increasing the low bank height ratio (XS2). Cross-sections along UT to Glade Creek are representative of the significant sediment deposition and decreasing pool depths occurring throughout the reach. The surveyed riffle cross-section along UT to Glade (XS5) has been affected by sedimentation but has maintained channel dimensions. Please refer to Appendix 4 for cross-section plots with annual overlays and Table 12 for morphology summaries. In general, the reachwide pebble counts on Glade Creek 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 MY4. This fining of sediment materials observed in MY3 has continued in MY4 for UT to Glade Creek. Please refer to Appendix 4 for pebble count plots with annual overlays. 1.2.4 Stream Areas of Concern UT to Glade Creek has continued to experience an increase in fine sediment throughout MY4. 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, sediment deposition has directed flow through Wetland D on the left floodplain of the channel resulting in active braiding. However downstream of Wetland D, willows have become more established along the banks and have helped maintain channel form and function. Along Glade Creek, there are a few isolated areas with minor to moderate bank erosion occurring along with loose coir matting. Previously noted in MY2, areas of scour near station 23+00 to 24+50 were planted with live-stakes in April 2019 to help stabilize the bank. Areas of concern are depicted on the CCPV Figure 3 and Table 6 in Appendix 2. 1.2.5 Hydrology Assessment A bankfull event was documented for Glade Creek and UT to Glade Creek on March 11, 2019 based on crest gage measurements. In MY1 through MY4, there has been at least four 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 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 Glade Creek II Restoration Project Monitoring Year 4 Annual Report – FINAL 1-4 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 MY4. Each time that the groundwater gage was downloaded in MY4, 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 2019 indicated higher than normal rainfall amounts occurred during the months of February, April, June, and October and lower than normal rainfall amounts occurred during March and September 2019. 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 One headcut that was noted in MY3 at the outflow of Wetland B where it meets Glade Creek Reach 2 (around station 22+80), continues to be visible in MY4. This headcut is likely to migrate further into the wetland without maintenance. Based on visual assessments in MY4, the area within Wetland D that is normally observed to have standing water is also lacking woody vegetation. Please refer to the CCPV Figure 3 in Appendix 2. 1.3 Monitoring Year 4 Summary The MY4 morphological surveys and visual assessments indicate that the majority of Glade Creek appears stable and functioning as designed; however, sediment deposition has caused a loss of channel function along a portion of UT to Glade Creek. The MY4 vegetation assessment resulted in an average planted stem density of 519 stems per acre and is exceeding the final success criterion of 260 stems per acre. In addition, five out of six plots individually met this requirement. The Site’s groundwater gage met the performance standard for MY4. The bankfull performance standard was met for the project in MY2. The MY4 visual assessment revealed a few areas of concern including pockets of invasive species present on the Site and isolated areas of bank scour. The continual maintenance of these areas of concern would benefit the Site long term and decrease additional impacts to the project. 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 annual monitoring 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. Glade Creek II Restoration Project Monitoring Year 4 Annual Report – FINAL 2-1 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).

Invasive Species Treatment Logs MEMO To: Harry Tsomides, NCDEQ From: Joe Secoges Date: 10/17/2019 Subject: Glade Creek II Mitigation Site Maintenance Report Tasks Preformed, - On October 1, 2019 kudzu was treated with Transline® herbicide (with surfactant and spray pattern indicator) at a rate of 21 oz per acre (max amount allowed on an acre in one year). The kudzu infestation is estimated to be about 1/3 of an acre. Other Notable -Information.- Due to the contract start date being September 30"' (at the end of the growing season) in addition to the extremely dry conditions, no other invasive plants were treated in 2019. However, due to the expectation that the kudzu will need treatments in multiple years for adequate control, Eastern Forest Consultants wanted to make sure that it was treated in 2019. A follow-up application on kudzu and initial treatment of all other target species will be conducted with leaf -on conditions in 2020.
