(Wildlands) completed a design bid build project at the Crooked Creek #2 Mitigation Site (Site) for the North Carolina Division of Mitigation Services (DMS) to restore and enhance 6,147 linear feet (LF) of perennial streams, enhance 1.0 acre of existing wetlands, restore and create 10.6 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 3,489.6 stream mitigation units (SMUs), 8.6 wetland mitigation units (WMUs), and 1.3 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 (WMP) for Goose Creek and Crooked Creek was completed in July 2012 (NCEEP, 2012). The stressors to watershed function identified in the WMP 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 WMP. The project goals established in the mitigation plan (Wildlands, 2013) were completed with careful consideration of goals and objectives that were described in the RBRP and to 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 Site construction and as -built survey was completed in 2015. Planting and baseline monitoring activities occurred in January and February 2016. Monitoring Year 1 (MY1) assessments were completed during August and September, 2016 to assess the conditions of the site. The average stem density for the Site is 320 stems per acre and is therefore on track to meet the interim Year 3 requirement of 320 stems per acres. The floodplain has dense herbaceous cover. Cross section dimensions appear stable and functioning as designed. Hydrologic success criteria were achieved in two of the 10 groundwater monitoring wells, and at least one bankfull event occurred on all monitored reaches.

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 Crooked Creek and two UTs to Crooked Creek; UT1 and UT2. Stream restoration consists of UT1 and Stream Enhancement consist of UT2 and Crooked Creek. 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 (WMP) for Goose Creek and Crooked Creek was completed in July 2012 (NCEEP, 2012). The stressors to watershed function identified in the WMP 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 WMP. 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 6 in Appendix 2 present the pre - 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 completed with careful consideration of goals and objectives that were described in the RBRP and to 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. Crooked Creek #2 Restoration Project Of Monitoring Year 1 Annual Report — FINAL 1-1 The project objectives have been defined as follows: • 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 1 Data Assessment Annual monitoring was conducted during MY1 to assess the condition of the project. The stream restoration success criteria for the Site follows the approved success criteria presented in the Crooked Creek #2 Project (Wildlands, 2013). 1.2.1 Vegetation Assessment Planted woody vegetation is being monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008). A total of 12 vegetation plots were established during the baseline monitoring within the project easement areas. All of the plots were installed using a standard 10 meter by 10 meter plot. The final vegetative success criteria will be the survival of 210 planted stems per acre in the riparian corridor along restored and enhanced reaches at the end of the seven year monitoring period (MY7). The interim measure of vegetative success for the Site will be the survival of at least 320 planted stems per acre at the end of year three of the monitoring period (MY3) and at least 260 stems per acre at the end of the fifth year of monitoring (MY5). Planted vegetation must average 10 feet in height in each plot at the end of the seventh year of monitoring. If this performance standard is met by MY5 and stem density is trending towards success (i.e., no less than 260 five year old stems/acre), monitoring of vegetation on the Site may be terminated provided written approval is provided by the United States Army Corps of Engineers in consultation with the NC Interagency Review Team. The MY1 vegetative survey was completed in September 2016, resulting in an average stem density of 320 stems per acre. Although the site has met the interim requirement of 320 stems/acre, only 6 of the 12 plots (SO%) individually met this requirement. The planted stem mortality was approximately 39% from the baseline density recorded in February 2016 at MYO of 526 stems/acre. There is an average of 8 stems per plot as compared to 13 stems per plot in MYO. Approximately 60% of the planted stems scored a vigor of 2 or less, indicating that they are unlikely to survive. This low vigor rating is due to the dry soil conditions and the suffocation of the surrounding herbaceous material. Please refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables. Crooked Creek #2 Restoration Project Of Monitoring Year 1 Annual Report — FINAL 1-2 1.2.2 Vegetation Areas of Concern While significant efforts were implemented during construction to control the invasive species within the Site, visual assessments in MY1 revealed areas in which follow up treatments may be warranted. Non-native invasive identified include Chinaberry (Melia azedarach), Chinese privet (Ligustrum sinense), Johnson grass (Sorghum halepense), and morning glory (Ipomoea sp.). The native invasive cattail (Typha latifolia) has colonized into Vegetation Plot 5, which may impact planted woody stem survival. The majority of the floodplain contains dense, native herbaceous cover; however, the competition for water could potentially impact the planted stems in drought conditions. Morning glory vines, and other invasive plants are impacting planted stems near photo point 33, which is located at the center, northern border of the easement. Despite herbicide treatment along the fence line, the vines have intruded further into the easement. The treated areas of Chinese privet on Crooked Creek Reach A and Reach B are showing increasing dominance of this species once again. Refer to Appendix 2 for the vegetation condition assessment table, Integrated Current Condition Plan View (CCPV), and reference photographs. 1.2.3 Stream Assessment MY1 Morphological surveys for were conducted in August 2016. Results indicate that the channel dimensions are stable and functioning as designed. In general, the cross sections on UT1 show little to no change in the bankfull area, maximum depth ratio, or width -to -depth ratio compared to baseline. Surveyed riffle cross sections fell within the parameters defined for channels of the appropriate Rosgen stream type (Rosgen, 1996). In general, substrate materials in the restoration reaches indicated maintenance of coarser materials in the riffle reaches and finer particles in the pools. The particle size distribution for MY1 riffle cross section 4 are similar or slightly larger than the as -built conditions, however pebble count data for riffle cross section 2 indicates increased deposition of fine sediment. This area will be watched in future monitoring years for embeddedness. Refer to Appendix 2 for the visual stability assessment table, CCPV map, and reference photographs. Refer to Appendix 4 for the morphological summary data and plots. 1.2.4 Stream Areas of Concern No stream areas of concern were identified during MY1. 1.2.5 Hydrology Assessment At least one bankfull event occurred on all reaches during the MY1 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 seven-year monitoring period. The two bankfull events must occur in separate years. Therefore, the performance criteria have been partially met in MY1. Refer to Appendix 5 for hydrologic data and graphs. 1.2.6 Wetland Assessment Ten groundwater monitoring gages (GWG 1-10) were installed during the baseline monitoring so that the data collected will provide an indication of groundwater levels throughout the wetland areas. The target performance criteria for wetland hydrology success consists of groundwater surface within 12 inches of the ground surface for 17 consecutive days (7.5 percent) of the defined 227 day growing season for Union County (March 23 through November 4) under typical precipitation conditions. Only two of the ten gages (GWG 6 and GWG7) met the performance criteria for MY1. GWG 6 met criteria for 26 consecutive days (15.5%) and GWG 7 recorded 18 consecutive days (8.0%). Both gages meeting success criteria are in the Wetland Restoration Zone A. According to onsite rain gage data and climate Crooked Creek #2 Restoration Project Of Monitoring Year 1 Annual Report — FINAL 1-3 data from a nearby USGS station, the site received less than typical amount of rain in 2016. The monthly rainfall in Feb -April and June fell below the 30% percentile for the area (USGS 2016). Refer to Appendix 5 for the groundwater hydrology data and plots. 1.3 Monitoring Year 1 Summary All restored streams within the Site appear stable and functioning as designed. The average stem density (320 stems per acre) for the Site is currently on track to meeting the MY7 success criteria; however only 50% of the vegetation plots individually meet the interim success criteria as noted in CCPV. Two of the 10 groundwater gages met the performance criteria in MY1. The bankfull performance criteria has been partially met in MY1. Summary information and data related to the performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Mitigation Plan documents available on DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Crooked Creek #2 Restoration Project Of Monitoring Year 1 Annual Report — FINAL 1-4 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).
