(Wildlands) completed a design -bid -build project at the Crooked Creek #2 Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DIMS) to restore and enhance 5,599 linear feet (LF) of perennial streams, enhance 1.0 acre of existing wetlands, restore and create 10.5 acres of wetlands, and restore and enhance 70,936 square feet (SF) of riparian buffer in Union County, NC. The Site is expected to generate 3,242.600 stream mitigation units (SMUs), 8.4 wetland mitigation units (WMUs), and 1.24 buffer mitigation units (BMU) for the Goose Creek watershed (Table 1). The Site is located off NC Highway 218 in the northern portion of Union County, NC in the Yadkin Pee -Dee River Basin; eight -digit Cataloging Unit (CU) 03040105 and the 14-digit Hydrologic Unit Code (HUC) 03040105040010 (Figure 1). The project streams consist of two unnamed tributaries (UT) to Crooked Creek, UT1 and UT2, and two reaches of the Crooked Creek mainstem (Reach A and Reach B) (Figure 2). Crooked Creek flows into the Rocky River 4 miles northeast of the Site near Love Mill Road at the Stanly County line. The adjacent land to the streams and wetlands is primarily maintained for agricultural and residential uses. The Site is within a Targeted Local Watershed (TLW) in the Lower Yadkin Pee -Dee River Basin Restoration Priority Plan (RBRP) (NCEEP, 2009). The Site is also located within the Goose Creek and Crooked Creek Local Watershed Plan (LWP). The final watershed management plan (WIMP) for Goose Creek and Crooked Creek was completed in July 2012 (NCEEP, 2012). The stressors to watershed function identified in the WIMP were sediment pollution and increases in peak stream flows resulting in impairments to aquatic habitat and aquatic life. Stream enhancement and restoration were identified as the best management opportunities to offset these impacts. Other stressors identified included nonpoint source runoff, degraded terrestrial habitat, and disconnected floodplains. Wetland enhancement and restoration was also identified as a best management opportunity to offset impacts related to these stressors. The wetland portion of the project was identified as a specific priority in the Project Atlas that accompanies the 2012 WIMP. The project goals established in the mitigation plan (Wildlands, 2013) were created with careful consideration of the goals and objectives described in the RBRP and address stressors identified in the LWP. The following project goals established include: • Improve wetland hydrologic connectivity; • Decrease sediment input into stream; • Create appropriate terrestrial habitat; • Decrease water temperature and increase dissolved oxygen concentrations; and • Decrease nutrient and adverse chemical levels. Overall, the Site in Monitoring Year (MY) six appears to be on track to meet the year seven requirements, with the exception of a few wetland areas. The planted vegetation on the Site appears to be doing well with isolated patches of invasive species that were treated in 2021. The average planted stem density for the Site is 513 stems per acre and is on track to meet the year seven requirement of 210 stems per acres. All 12 vegetation plots individually met the year seven success criteria. The planted buffer is establishing well on the Site and tree growth accelerated by 47% in MY6 with an average stem height of 14 feet. Invasives treatments occurred in March and September 2021 and have been effective, significantly controlling the invasive species previously identified within the Site, although the areas have remained on the CCPV maps to monitor for re -sprouts in MY7. Channel dimension and profiles on UT1 appear stable and functioning as designed with only minor fluctuations. Groundwater hydrologic success criteria was achieved in four of the eleven groundwater monitoring gages. Although the success criteria for bankfull for the project was met in MY2, additional bankfull events were recorded in MY6 on WCrooked Creek #2 Restoration Project (94687) Monitoring Year 6 Annual Report — Final project streams. Annual monitoring will continue to be conducted through MY7 with an expected closeout in 2023.

The Site is located off NC Highway 218 in the northern portion of Union County, NC (Figure 1). Located in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998), the project watershed includes primarily agricultural forested and developed land. The drainage area for the project Site is 24,619 acres. The project streams consist of two streams (Crooked Creek and UT2) that underwent Stream Enhancement as well as one stream (UT1) which underwent Stream Restoration. The Site is located within a Targeted Local Watershed (TLW) in the Lower Yadkin Pee -Dee River Basin Restoration Priority Plan (RBRP) (NCEEP, 2009). The Site is also located within the Goose Creek and Crooked Creek Local Watershed Plan (LWP). The final watershed management plan (WIMP) for Goose Creek and Crooked Creek was completed in July 2012 (NCEEP, 2012). The stressors to watershed function identified in the WIMP were sediment pollution and increased peak stream flows resulting in impairments to aquatic habitat and aquatic life. Stream enhancement and restoration were identified as the best management opportunities to offset these impacts. Other stressors identified included nonpoint source runoff, degraded terrestrial habitat, and disconnected floodplains. Wetland enhancement and restoration was also identified as a best management opportunity to offset impacts related to these stressors. The wetland portion of the project was identified as a specific priority in the Project Atlas that accompanies the 2012 WIMP. Prior to construction activities, the streams on the Site had been channelized and the adjacent floodplain wetland areas had been cleared and ditched to provide drainage for surrounding pasture. These land use activities resulted in bank instability due to erosion and livestock access, lack of riparian buffer, and altered hydrology. Stream Incision, lateral erosion, and widening also resulted in degraded aquatic and benthic habitat, reduction in quality and acreage of riparian wetlands, and lowered dissolved oxygen levels in the stream. Table 4 in Appendix 1 and Table 11 in Appendix 4 present the post -restoration conditions in more detail. 1.1 Project Goals and Objectives This mitigation Site is intended to provide numerous ecological benefits within the Yadkin Pee -Dee River Basin. While many of these benefits are limited to the Crooked Creek 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. The project goals established in the mitigation plan (Wildlands, 2013) were created with careful consideration of the goals and objectives described in the RBRP and address stressors identified in the LWP. The following project goals established include: • Improve wetland hydrologic connectivity; • Decrease sediment input into stream; • Create appropriate terrestrial habitat; • Decrease water temperature and increase dissolved oxygen concentrations; and • Decrease nutrient and adverse chemical levels. The project objectives have been defined as follows: WCrooked Creek #2 Restoration Project (94687) Monitoring Year 6 Annual Report — Final 1-1 • Construct stream channels that will remain relatively stable over time and adequately transport their sediment loads without significant erosion or aggradation; • Construct stream channels that maintain riffles with coarse bed material and pools with finer bed material; • Provide aquatic and benthic habitat diversity in the form of pools, riffles, woody debris, and in - stream structures; • Add riffle features and structures and riparian vegetation to decrease water temperatures and increased dissolved oxygen to improve water quality; • Construct stream reaches so that floodplains and wetlands are frequently flooded to provide energy dissipation, detain and treat flood flows, and create a more natural hydrologic regime; • Construct fencing to keep livestock out of the streams; • Raise local groundwater table through raising stream beds and plugging agricultural drainage features; • Perform minor grading in wetland areas as necessary to promote wetland hydrology; and Plant native tree species to establish appropriate wetland and floodplain communities and retain existing, native trees where possible. 1.2 Monitoring Year 6 Data Assessment The following sections present the MY6 data collected between April and November 2021 to assess the condition of the project. The success criteria for the Site follows the approved success criteria presented in the Crooked Creek #2 Project Mitigation Plan (Wildlands, 2013). 1.2.1 Vegetation Assessment A total of 12 standard 10-meter by 10-meter permanent vegetation plots were established during the baseline monitoring within the project easement area. The final vegetative success criteria are the survival of 210 planted stems per acre with an average height of 10 feet in each plot in the riparian corridor along restored and enhanced reaches at the end of the seven-year monitoring period (MY7). The MY6 vegetation survey was completed in September 2021 resulting in an average stem density of 513 stems per acre. All 12 vegetation plots individually met the year seven requirement of 210 stems/acre, with an average of 13 stems per plot. The MY6 average stem height for the Site is 14 feet, increasing from 10 feet in MY5. All plots except for plots 6, 9, and 12 have individually met the 10-foot requirement. Plot 6 contains herbaceous vegetation, which is competing with the stems, but has shown improvement from MY5 to MY6 with an average stem height of 9 feet. Plots 9 and 12 are located within the Crooked Creek riparian corridor and are largely shaded by mature canopy with average stem heights of 7 and 6 feet respectively. The planted stem height appears to be trending toward meeting the 10-foot requirement in each plot, with an overall increase in height of 47% from MY5 to MY6 and all individual plots exceeding the MY7 stem density requirement. The vegetation across the site is performing well and the site has responded well to the invasive species treatment that DIMS has contracted throughout the 2020 and 2021 growing seasons; refer to section 1.2.2 for further details. Supplemental plantings that occurred in January 2018 are established and have survived multiple growing seasons. Overall, strong tree growth across the Site and the shrub/herbaceous species colonization of the wetter portions of the site have created a healthy riparian buffer. Please refer to Appendix 2 for vegetation plot photographs and the overall vegetation condition assessment table. The vegetation data tables are located in Appendix 3. Please refer to Appendix 6 for the Invasive Species Treatment Logs. WCrooked Creek #2 Restoration Project (94687) Monitoring Year 6 Annual Report — Final 1-2 1.2.2 Vegetation Areas of Concern Generally, the vegetation within the Site is healthy with a few areas of invasive plant species present. Invasive species noted on the site include cattail (Typha latifolia), Japanese honeysuckle (Lonicera japonica), Chinese privet (Ligustrum sinense), and balloon vine (Cardiospermum halicacabum). The native invasive species, cattail (Typha latifolia) continues to surround vegetation plot 5, but it is not adversely affecting tree growth in the plot. The colony is established but has not expanded beyond the area adjacent to vegetation plot 5. The percent of easement area covered in invasive species remains at 3% of the easement area in MY6 and is consistent with the MY5 percentage. Treated invasive areas have remained on the MY6 CCPV maps to monitor for re -sprouts in MY7. If treatments are successful in MY7 and treated areas are removed from the CCPV maps, then the remaining mapped invasive species area would account for only 0.4% of the easement area. After the September 2021 treatment, very few privet, tree of heaven, or honeysuckle resprouts were observed during the Q3 and Q4 Site walks. DIMS will continue to treat these invasive species as needed through closeout. Additionally, mowing within the easement during MY5 continued into MY6. There was evidence of mowing along the easement line in the left floodplain of Crooked Creek during the April 2021 site visit. DIMS installed additional easement signs and a clear marker line connecting the easement signs with white tape to deter further mowing. No additional easement encroachments have been observed since. Wildlands will continue to monitor these areas for any evidence of future encroachment or further advancement of the previously noted areas of concern. Refer to Appendix 2 for the vegetation condition assessment table and the CCPV maps for MY6 vegetation areas of concern, and Appendix 6 for the invasive species treatment log. 1.2.3 Stream Assessment The MY6 morphological survey conducted in April 2021 indicated that UT1 channel dimensions appear stable and functioning as designed. In general, the cross -sections show only minor changes in the bankfull area, maximum depth ratio, or width -to -depth ratio compared to the baseline survey. Surveyed riffle cross -sections continue to fall within the parameters defined for channels of the appropriate Rosgen stream type (Rosgen, 1996). Cross-section 2 continued to fine in MY6 but may wash through the channel with a large storm event. Cross -sections 3 and 4 have maintained designed dimensions since removal of the beaver dam. Refer to Appendix 2 for the visual stability assessment table, CCPV map, and stream photographs. Refer to Appendix 4 for the morphological summary data and plots. 1.2.4 Stream Areas of Concern There were no stream areas of concern for UT1 or UT2 recorded for MY6. 1.2.5 Hydrology Assessment The stream hydrology success criteria require two bankfull events must occur in separate years within the seven-year monitoring period. Although, the stream hydrology success criteria were met in MY2, bankfull events continue to be recorded on Crooked Creek, UT1, and UT2. Events were verified with stream gages or visual indicators, such as wrack lines. During MY6 there were 6 bankfull events recorded on UT1. In addition to bankfull assessments, stream baseflow is being monitored on UT1 to demonstrate stream flow regimes are sufficient to establish an ordinary high water mark. UT1 recorded 92 days of consecutive baseflow in MY6. Refer to Appendix 5 for hydrologic plots and photographs of documented bankfull events. WCrooked Creek #2 Restoration Project (94687) Monitoring Year 6 Annual Report — Final 1-3 1.2.6 Wetland Assessment At total of 11 groundwater gages (GWG) have been installed throughout the wetland areas to provide groundwater level data and one soil temperature probe was installed near GWG2. The target success criteria for wetland hydrology success consists of a groundwater surface within 12 inches of the ground surface for 17 consecutive days (7.5 %) of the defined 226 day growing season for Union County (March 23 through November 4) under typical precipitation conditions. Fewer GWGs met the success criteria in MY6 compared to previous monitoring years, with 4/11 gages meeting. Generally, the gages that met were located in Wetland Restoration Zone A away from the left floodplain of UT1: GWG3 (18 days,7.9%), GWG6 (25 days, 11%), GWG7 (30 days, 13.2%), and GWG8 (26 days, 11. 5%). GWGs 6, 7, and 8 have consistently met the success criteria each monitoring year and GWG3 has met success criteria each monitoring year except MY1. Within the group of groundwater gages not meeting success criteria in MY6 (GWGs 1, 2, 4, 5, 9, 10, and 11), GWG2, and GWGS met in both MY4 and MY5, missing the success criteria by 3 days in MY6. GWG1, GWG9, and GWG10 are all located on the wetland edges and have not consistently met throughout the monitoring period, including MY6. These three only met in MY4, which is most likely due to the substantial rainfall that occurred in the later winter and early spring, enabling the wetlands to retain high groundwater surface levels. GWG4 has yet to meet criteria and GWG11 has not met since it was installed in March 2020. However, as detailed in the MY5 report, there is evidence from both the vegetation and the developing soils in the areas surrounding both gages that the floodplain may be saturated during a period of the year. In MY6, total rainfall from January to October was 24.58 inches, which is 45% less than MY5 rainfall of 45.15 inches. The rainfall in 2021 in Union County has been isolated, very dry, and less than the 30% annual average according to the USGS Station 351218080331345 at Belk Scout Camp, located about 5 miles away from the Site. A 30-day rolling precipitation total was added to the GWG plots in MY6 along with the 30t" and 70t" percentile rainfall data for each month for Union County. The additional data helps explain changes in the groundwater surface level recorded by the gages throughout the year by totaling the rainfall within the previous thirty days. The plots show that the precipitation in later winter/ early spring was average, and the water table level remained above criteria level for all GWGs in the period of the year with average rainfall. However, an exceptionally dry spring resulted in a greatly reduced groundwater surface that was not able to recharge from the precipitation deficit, even with average precipitation amounts in the late summer and fall. DIMS will conduct a soil study in Winter 2022 2023 to determine which wetland assets would potentially be removed at closeout. Soil temperature data has indicated that the ground temperature starts to rise in early March and remains above the 41-degree Fahrenheit threshold throughout the growing season. Supplemental soil temperature data has been collected since 2019, however no bud burst, or leaf drop data has been gathered to verify the growing season dates with the soil probe data. Please refer to Appendix 7 for supplemental soils temperature and adjusted groundwater gage data. Please refer to Appendix 5 for the groundwater hydrology data, plots, and rainfall data. 1.2.7 Wetland Areas of Concern Currently, there are no areas of concern within the wetland areas. Repair work completed on the headcut near Wetland Creation Zone B, previously reported in MY3, has not retreated further. There is some evidence that water has continued to move through this area where vegetation has not fully established. However, the headcut is not threatening the stability of the Site or the riparian buffer. The headcut area will continue to be monitored in MY7. Refer to Appendix 2 for wetland photographs. WCrooked Creek #2 Restoration Project (94687) Monitoring Year 6 Annual Report — Final 1-4 1.3 Monitoring Year 6 Summary In general, the dimensions and profiles of the restored and enhanced stream channels appear stable and are functioning as designed. UT1 retains the ability to transport sediment and maintain channel form during bankfull events. The Site has withstood several bankfull events and has met success criteria for the project. The average planted stem density of 513 stems per acre and the average planted stem height of 14 feet across the Site indicates that the riparian buffer is establishing within the site. The Site has responded well to previous supplemental plantings and invasive species treatments. Due in part to below average rainfall, 4/11 groundwater gages met success criteria in MY6. The area of Wetland Restoration Zone A to the left of UT1, represented by GWGS 4 and 11, may be at risk of failing to meet success criteria during the seven-year monitoring period. 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 DIMS upon request. Crooked Creek #2 Restoration Project (94687) Monitoring Year 6 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 a Trimble handheld GPS with sub -meter accuracy and processed using Pathfinder and ArcGIS. Crest gages and pressure transducers were installed in surveyed riffle cross -sections during annual Site visits. 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).

Invasive Species Treatment Logs We Make a Difference I N T E R N AT 1 0 N A L Progress Report for Crooked Creek II (DMS #94687) Invasive Vegetation Management 13 October 2020: Jason York and Drew Powers applied 10 gallons of 3% Rodeo (glyphosate) as a foliar spray on privet (Ligustrum spp.) along the northern bank of Crooked Creek. Approximately 60 feet from the banks were treated. Other invasive plants treated included Sacred Bamboo (Nandina domestica), Burning Bush (Euonymus alata), Japanese Honeysuckle (Lonicera japonica), and Callery Pear (Pyrus calleryana). Privet and Callery Pear were also treated with 20% Garlon 4 in Bark Oil Blue as a basal bark application near the northern most easement boundary. No stems were treated that were tall enough to fall on the adjacent fence line. Attached is a map showing the approximate area that was treated. 23 November 2020: Jason York and Drew Powers applied 8 gallons of 4% Garlon 4 with 4% Methylated Seed Oil in Water as a foliar/basal hybrid treatment for privet (Ligustrum spp.) in non -aquatic areas along the eastern and southern portions of the Crooked Creek II easement. Several stems of Tree of Heaven (Ailanthus altissima) were also treated using the hack and squirt method with 50% glyphosate in the problem area identified on the map in the IFB. A total of 32 ounces of 50% glyphosate were used. A dense stand of young privet occurs along a slope on the southeastern side of Crooked Creek. This population will be sprayed in the spring 2021. Areas of previous treatment on October 13 are responding well. Attached is a map showing the approximate area that was treated. 29 March 2021: Jason York and Drew Powers applied 16 gallons of 4% Garlon 4 Ultra with 4% Methylated Seed Oil in Water as a foliar/basal hybrid treatment on privet (Ligustrum spp.). Privet was treated in the western portion of the easement as well as on the southern side of Crooked Creek near the easement boundary. Large populations of Japanese honeysuckle are present within the easement, particularly in areas where previous treatment of privet reduced competition. Honeysuckle will be targeted later in the growing season of 2021. Attached is a map showing the approximate area that has been treated thus far. 29 September 2021: Jason York and Drew Powers applied 9 gallons of 3% Rodeo as a foliar spray on privet (Ligustrum spp.), Tree of Heaven (Ailanthus altissima), honeysuckle (Lonicera japonica), and balloon vine (Cardiospermum halicacabum). The majority of the treatment was focused on privet seedlings and root sprouts scattered throughout the easement on both banks of Crooked Creek. Two small patches of balloon vine were treated near the eastern boundary of the easement. Target populations of invasive species within the easement have been greatly reduced since the beginning of the contract; however, as privet populations decrease, Japanese honeysuckle spreads rapidly. Climbing vine are cut from trees and large patches are sprayed, but treatment of all honeysuckle stems is not practical is it would damage surrounding desirable vegetation Attached is a map showing the approximate area that was treated.
