(Wildlands) has reviewed the Division of Mitigation Services (DMS) comments from the Draft Monitoring Year 2 report for the Glade Creek II Mitigation Project. The following Wildlands responses to DMS's report comments are noted in italics lettering. DMS comment; Project overview — It is stated Table 6 (post -restoration visual assessment) describes pre -restoration conditions. Please clarify or amend. Wildlands response; This sentences in Section 1.1 has been revised to clarify that both pre- and post - restoration conditions are represented in Tables 4 and 6. DMS comment; Section 1.2 — spelling correction, "follow" to "follows" (first sentence). Wildlands response; The text in Section 1.2 was edited to correct spelling error. DMS comment; If possible please reformat the asset totals to reflect the nearest tenth SMU (2141 to 2140.7 "R", and 26 to 25.8 "RE"). Wildlands response, In Table 1, these asset totals were reformatted to reflect the nearest tenth SMU. DMS comment; It is suggested that dredging out the top of UT Reach 1(preservation) would help minimize the fine sediment accumulation and active braiding. Does Wildlands feel that this segment would not fill in again if the preservation channel were dredged out? The watershed upstream from the UT has always been in cattle usage; how would dredging out the channel prevent further aggradation? Wildlands response; The sedimentation that is occurring starts at UT to Glade Creek Reach 1 in the Restoration Reach, approximate STA 11+00, below the preservation reach. Digging out the channel is not a long-term preventative method. The sedimentation occurring is going to be an ongoing concern unless it is addressed at the source, upstream of the project area. Through the few years Wildlands has Wildlands Engineering, Inc. • phone 704-332-7754 • fax 704-332-3306 • 1430 S. Mint Street, # 104 • Charlotte, NC 28203 k rV WILDLANDS ENGIN EERJNC been monitoring this project post -construction, we have observed the sediment deposits are being flushed out over time with larger flows. DMS comment; UT to Glade Creek field visit by DMS staff on 9/6/17 showed that noticeable aggradation had developed in the UT Reach 2 restoration segment flowing through Wetland D and downstream. Sediment accumulation is described as occurring around STA 11+00 (preservation reach) but not mentioned along Reach 2. Was the sedimentation across the entire UT (Reaches 1 and 2) observed? If so, is it all reflected in the 100 LF noted in the visual assessment table for the UP Wildlands response; Wildlands conducted a final CCPV site walk on December 4, 2017 and did not observe the sediment accumulation along UT1 Reach 2 as noted above from the DMS site walk in September. A large rain event was recorded for the area in October (11" rainfall) that could have flushed out the sediment in the lower portion of UT1 noted by DMS. Wildlands will plan to monitor this area closely during subsequent site visits and will report any adjustments noted on site. DMS comment; It is noted in the summary section that UT to Glade is not flowing properly due to the sediment and vegetation in the channel. The preservation reach was noted in the narrative, however much of the restoration reach (STA 11+29 to 14+48) showed excessive sediment accumulation during the DMS visit. Aerials do not show recent upstream logging as of October 2016, and cattle have always been present upstream of this reach. Has Wildlands observed upstream logging or new impacts other than cattle that might be a sediment source? Wildlands response; As stated in the previous DMS comment, Wildlands did not observe sedimentation in the some locations as DMS. This is most likely due to larger rainfall events occurring between site visits. Wildlands observed sediment deposition in the UT to Glade Creek Reach 1 restoration reach, not the preservation reach. During the MY2 site assessments, Wildlands observed construction equipment (i.e. bull dozer) on multiple occasions upstream of the project easement, but it is unclear what land management activities were being conducted. DMS comment; Would Wildlands recommend dredging out the restoration UT channel as a long-term adaptive management solution or would the channel just fill in again because of the lack of adequate gradient and orientation through a restored wetland? As both the project designer and monitor, please provide more information on the long-term viability of any management actions along the entire length of the UT so DMS can make informed decisions about any potential adaptive management. Wildlands response; Wildlands believes we can temporarily improve stream function on UT to Glade Creek by hand removing the sediment that appears to be coming from erosion in the upstream pasture and by hand removing the existing herbaceous vegetation. Together, these factors are forcing water onto the adjacent wetland/floodplain and bypassing the channel. Wildlands cannot guarantee that this is a long-term solution, but rather a jump start to improve channel function while the riparian vegetation matures. Most likely as the planted trees continue to grow, they will provide shade and instream vegetation will not be able grow as readily. The sedimentation that is occurring is going to be an ongoing concern unless it is addressed at the source, upstream of the project area. Through the few years Wildlands has been observing this project post -construction, we have observed the sediment deposits are being flushed out overtime with larger flows. Wildlands will continue to monitor the deposition and inform DMS of any changes. Wildlands Engineering, Inc. • phone 704-332-7754 • fax 704-332-3306 • 1430 S. Mint Street, # 104 • Charlotte, NC 28203 kt� WILDLANDS ENGINEERING DMS comment; Visual assessment for UT - calculation for stable percent should be 78% not 88%, based on 100 LF impacted out of 448 LF assessed. Please clarify or correct. Wildlands response; Table 6b has been updated to show 78% of the channel is stable. DMS comment; Stationing on maps for the UT (0+00 to 3+45, starting at the restoration reach) do not match stationing numbering with the asset table (10+00 to 14+48 starting at the preservation reach); in addition, Reaches 1 and 2 on the CCPV figures appear incorrectly labelled (fig. 3) or unclear (fig. 2). Please clarify or correct. Wildlands response; Wildlands has revised both the Asset Table 1 and the figures stationing to accurately represent the reaches on UT to Glade Creek. DMS comment; Changing the vertical scaling on the longitudinal profile for the Ut would help show more subtle changes in the profiles. Wildlands response; Longitudinal profile vertical scaling has been revised for UT to Glade Creek as requested above. DMS comment; Table 10 (CVS table) should be printed landscape or on a larger fold out sheet. Wildlands response; Table 10 has been printed in landscape layout in the final submittal. DMS comment; It would be helpful in future reports to have a wrack line photo or two to accompany the bankfull events table, especially for smaller reaches (Ut). Wildlands response; When possible, Wildlands will include wrack line photo(s) in future reports to accompany the bankfull event table. DMS comment; Long -pro plot for the UT appears upside down in the hard copy. Please make sure any printed copy graphs and pages read right side up when printed. Wildlands response; Hard copies of the Final Monitoring Report will be corrected for this issue. Enclosed please find four (4) hard copies and one (1) electronic copy on CD of the Final Monitoring Report. Please contact me at 704-332-7754 x110 if you have any questions. Sincerely, Kirsten Y.

Mint Street, # 104 • Charlotte, NC 28203 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 2,167 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 Cataloging Unit (CU) 05050001 and the 14 -digit Hydrologic Unit Code (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 4 miles northeast of the Site near Fox Trot Lane in the Town of Hooker, Alleghany County. 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 a priority subwatershed for stream and wetland restoration (and habitat protection), Middle Glade Creek, 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 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 0 beginning in May 2016. Storm repairs prior to project closeout were completed in April 2016. Monitoring Year 2 (MY2) activities occurred between May and November 2017. MY2 profiles closely match the design parameters. Cross-section widths and pool depths slightly exceed design parameters, but are within a normal range of variability. The Site's overall average planted stem density of 580 stems/acres exceeds the interim vegetation success criterion of 320 stems/acres for MY3. Hydrologic success criteria was achieved for MY2 in the groundwater gage (GWG), and at least one bankfull event occurred on all monitored reaches. The Site has fully met the hydrological success criteria since bankfull events were also documented during MY1.

The Site is located in the New River Basin, eight -digit Cataloging Unit (CU) 05050001 and the 14 -digit Hydrologic Unit Code (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 2,167 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. Storm repairs prior to project closeout were completed in April 2016. Turner Land Surveying completed the as -built survey in January 2016 and the storm repairs were judged to have not resulted in changes that would warrant a revised as -built survey. The Site is located on a tract of land owned by the Sharon W. Beck. A 12.8 -acre conservation easement on the tract 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, exotic invasive plant species, and the valley fill buried hydric soils. 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 Basin Restoration Priorities Plan (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. Glade Creek II Restoration Project Monitoring Year 2 Annual Report— FINAL 1-1 The project objectives have been defined as follows: • Restoration and enhancement of approximately 2260 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 (December 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 2 Data Assessment Annual monitoring was conducted between May and November 2017 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 Planted woody vegetation is being monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-NCEEP Level 2 Protocol (Lee et al., 2008). A total of six vegetation monitoring plots were established during the baseline monitoring within the project easement areas using a standard 10 by 10 meter plot. The final vegetation success criterion will be 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 interim measure of vegetation success for the Site is the survival of at least 320 planted stems per acre at the end of year three of the monitoring period. Please refer to Figure 3 in Appendix 2 for the vegetation monitoring locations. The MY2 vegetation survey was completed in September 2017, resulting in an average planted stem density of 580 stems per acre. The Site has met the interim requirement of 320 stems per acre, with 5 of the 6 plots (83%) individually meeting this requirement. The average stem height is 2.8 feet and approximately 90% of the planted stems have a health score (vigor) of 2 or greater. However, 50% of these stems have a vigor of 2; whereas in MY1, 50% of the stems had a vigor of 4. The increase in poor health is a result of dry soil conditions, insects and suffocation. Vegetation monitoring plot 1 contains only 6 stems, resulting in a density of 243 stems per acre; whereas plot 3 contains 22 stems with a density of 809 stems per acre. Please refer to Appendix 2 for vegetation plot photographs and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern The MY2 vegetation monitoring and visual assessment revealed few vegetation areas of concern. Small patches (approximately 6.3%) of bare or poor herbaceous cover in the riparian area of Glade Creek Reach 1 and 2 were observed. Supplemental planting is recommended in vegetation plot 1 and throughout the entire Site since the overall vigor of planted and surrounding stems have declined. Refer to Figure 3 in Appendix 2. Glade Creek II Restoration Project Monitoring Year 2 Annual Report— FINAL 1-2 1.2.3 Stream Assessment Morphological surveys for MY2 were conducted in May 2017. Results indicate that the channel dimensions are stable and functioning as designed. However, the Glade Creek cross-section widths and pools depths have slightly increased compared to MY1; whereas, UT to Glade Creek cross-section dimensions are relatively the same as MY1. In general, the substrate material within Glade Creek remained the same as MY1; however, the D50 for UT to Glade Creek changed between MY1 and MY2. The UT to Glade Creek reachwide material resulted in sand (0.8mm) during MY2 versus gravel material (11.9mm) during MY1. The material in cross-section 5 resulted in a Dso of 0.7mm (sand) during MY2 whereas MY1 reflected a coarser gravel of 22.6. The surveyed longitudinal profile data for the project streams illustrates that bedform features are maintaining lateral and vertical stability. The longitudinal profiles on Glade Creek and UT to Glade Creek showed slight change from MY1 in slope (riffle, water surface, bankfull) and pool -to -pool spacing. The overall pattern of all project streams remained the same compared to the baseline data. Refer to Appendix 2 for the visual stability assessment table and the CCPV map. Refer to Appendix 4 for the morphological summary data and plots. 1.2.4 Stream Areas of Concern UT to Glade Creek has experienced an increase in fine sediment throughout MY2. Approximately 6-8" of sediment deposition has accumulated and is impeding the flow beginning at station 11+00 for approximately 100 LF. As a result, the water has formed a braided system on the floodplain and the pool located at the first step structure around station 11+00 has filled with sediment, leaving little pool habitat. Land management activities upstream of the project easement are most likely contributing to the sedimentation on UT to Glade Creek; however, cattle activity adjacent to the beginning of UT Reach 1 was observed during MY2 site visits and could be attributing to the sediment flux observed. A fallen pine tree was also noted on UT to Glade Creek. The tree is currently crossing the channel; however, it is not currently affecting the stream flow. The limbs are holding the tree off the ground but once the limbs decay and break, the tree will most likely create a barrier within the channel. There are a few areas of minor scour and erosion along Glade Creek. The brush mattress around station 18+00 has been displaced; therefore, exposing the bank and minor scouring has occurred. In addition, the left bank between stations 23+00 and 25+00 are showing signs of scour under the brush mattress and behind the boulders. Minor adaptive management is recommended along UT to Glade Creek and Glade Creek. Within the upstream section of UT to Glade Creek Reach 1, hand removal of the sediment deposit and hand removal of the herbaceous material within the channel are recommended to temporarily improve stream function and reduce the active braiding. Where the tree has fallen across the UT to Glade Creek, removal of the fallen tree is recommended to prevent future blockage. Wildlands recommends replacing the brush mattresses on Glade Creek where bank erosion is occurring, and the brush mattress is no longer intact with the bank. Adding live stakes on the left bank between stations 23+00 and 25+00 is also recommended for bank stabilization. 1.2.5 Hydrology Assessment At least one bankfull event occurred on all reaches during the MY2 data collection, which was recorded on crest gages and by visual indicators. Two bankfull flow events must be documented on the restoration reaches within the five-year monitoring period. The two bankfull events must occur in separate years. A bankfull event was also recorded during MY1; therefore, the Site has met the bankfull success criteria for the project. Refer to Appendix 5 for hydrologic data and graphs. Glade Creek II Restoration Project Monitoring Year 2 Annual Report— FINAL 1-3 1.2.6 Wetland Assessment One groundwater monitoring gage (GWG 1) was established during the baseline monitoring within the restoration area using logging hydrology pressure transducers. 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 groundwater surface within 12 inches of the ground surface for 21 consecutive days (12.5%) of the defined 168 day growing season for Alleghany County (April 26th to October 111h) under typical precipitation conditions. The Site does not contain a rainfall gage; therefore, the daily precipitation data was collected from closest NC CRONOS Station, Glade Valley 3.0 ENE. The GWG 1 recorded 169 consecutive days (100%), meeting the performance standard for MY2. According to the climate data from nearby NC CRONOS station, the Site received less than typical amounts of rain in 2017; however, October received a substantial amount of rainfall. Please refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology data and plots. 1.2.7 Wetland Areas of Concern Currently there are no wetland areas of concerns. 1.3 Monitoring Year 2 Summary Glade Creek appears stable and functioning as designed; however, UT to Glade Creek is not flowing properly due to the sediment and vegetation in the channel. The average planted stem density (580 stems per acre) is currently on track to meet the MY3 success criterion. Only one plot does not meet the interim success criterion as noted in CCPV. The Site's groundwater gage met the performance standard for MY2 and the bankfull performance standard has been met for the project. The Site has fully met the bankfull hydrological success criteria since bankfull events were also documented during MY1. Some minor adaptive management would be beneficial to the Site. The areas of concern appear minor, but repairs and maintenance of these areas 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 2 Annual Report— FINAL 1-4 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 quarterly. 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).
