(Wildlands) implemented a full delivery project in Orange County, NC at the Buckwater Mitigation Site (Site) for the North Carolina Department of Environmental Quality Division of Mitigation Services (DMS) to restore and enhance a total of 16,276 linear feet of perennial and intermittent streams. The Site is expected to generate 12,621.936 stream mitigation units (SMUs) when calculated along stream centerlines. The Site is located approximately 4.5 miles northeast of Hillsborough, NC (Figure 1) in the Neuse River Basin 8-Digit Hydrologic Unit Code (HUC) 03020201 and NC Division of Water Resources (NCDWR) Subbasin 03-04-01 and is within the DMS-targeted HUC 03020201030030. The Site contains Buckwater Creek and 14 unnamed tributaries. Buckwater Creek, T1, T2, T3, T4, T5, T6, T6A, T7, and T9 are perennial streams, while T4A, T413, T613, T7A and T8 are intermittent streams. The Site streams drain to the Eno River, which flows to Falls Lake, and are classified as Water Supply Waters (WS-IV) and Nutrient Sensitive Waters (NSW). The 51.84-acre Site is protected with a permanent conservation easement. The Site is located within a Targeted Local Watershed as discussed in the 2010 Neuse River Basin Restoration Priorities (RBRP) (Breeding, 2010), which highlights the importance of riparian buffers for stream restoration projects. Since at least 1938, cattle have grazed on three of the Site properties. The remainder of the Site that is not forested was used for cultivating hay. The project goals established in the Mitigation Plan (Wildlands, 2017) were developed considering the goals and objectives listed in the Neuse River RBRP and include: • Reconnect channels with floodplains and riparian wetlands to allow a natural flooding regime; • Improve the stability of stream channels; • Exclude cattle from project streams; • Restore and enhance native floodplain and streambank vegetation; • Improve instream habitat; and • Permanently protect the Site from harmful land uses. The project will contribute to achieving the goals for the watershed listed in the Neuse River RBRP and provide ecological benefits within the Neuse River Basin. While benefits such as habitat improvement and geomorphic stability are limited to the Site, reduced nutrient and sediment loading have farther reaching effects. In addition, other implemented and planned projects in the same watershed and basin as this Site will realize cumulative benefits. Site construction and planting were completed in April 2019. As -built surveys were conducted between January 2019 and April 2019. Monitoring Year 2 (MY2) assessments and site visits were completed between January and October 2020 to assess the conditions of the Site. Overall, the Site has met the required stream success criteria for MY2. The average stem density for the Site is 334 planted stems per acre with 9 out of 19 vegetation plots on track to meet the MY3 interim requirement of 320 planted stems per acre. A supplemental planting will occur in winter 2021 to offset the mortality rates at the Site. Two areas with poor herbaceous cover, totaling 1.4 acres, have been noted and will continue to be addressed during MY3. Areas of concern, along Buckwater Creek Reach 7, identified by the IRT were repaired in April 2020. In August 2020, in -stream vegetation treatment was conducted due to sediment transport concerns. Pool cross -sections on T5 deviated from the design during MYO but have since stabilized. Bankfull or geomorphically significant events were recorded on all stream reaches. Additionally, all the flow gages have recorded baseflow for more than 30 consecutive days during MY2.

Both the Neuse River and Falls Lake are designated as Nutrient Sensitive Waters. The Site streams drain to the Eno River and are within Hydrologic Unit Code (HUC) 03020201030030, which is a Targeted Local Watershed (TLW) (Figure 1). The Site lies in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The drainage area for the Site is 2,259 acres (3.53 square miles) consists primarily of agricultural and forested land. The project streams include Buckwater Creek and fourteen unnamed tributaries. Mitigation work within the Site includes restoration, enhancement I, and enhancement II of 16,276 linear feet of intermittent and perennial stream channels. The riparian areas were planted with native vegetation to improve habitat and protect water quality. The final Mitigation Plan (Wildlands, 2017) was submitted to and accepted by DMS in December 2017. Construction activities were completed by Ecotone, Inc. in April 2019. Planting and seeding activities were completed by Bruton Natural Systems, Inc. in April 2019. Baseline monitoring (MYO) was conducted between January and April 2019. Annual monitoring will occur for seven years with the close-out anticipated to commence in 2026 provided success criteria are met. Appendix 1 provides additional details on project activity, history, contact information, and watershed background information for the Site. The Site is located on eleven parcels under nine different landowners. A conservation easement was recorded on 51.84 acres. The project is expected to provide 12,621.936 SMUs at closeout. A project vicinity map and directions are provided in Figure 1, and project components/assets are illustrated in Figure 2. Project Goals and Objectives Prior to construction activities, the primary causes of Site degradation were stream channelization and livestock grazing, both of which originated prior to 1938. Agricultural activity remained intensive through the 1990s with several thousand beef cattle and three hog houses. Currently, approximately 130 cows graze on three properties and non -forested land is used for cultivating hay. Several ponds along Buckwater Creek, T3, and T5 were built between 1938 and 1955. According to 1955 aerial photography, the top 1,000 feet of Buckwater Creek on the Site were channelized. Landowners maintained lower Buckwater Creek below Walnut Hill Drive as a straightened channel until the 1990s. Table 4 in Appendix 1 and Tables 10a through 10c in Appendix 4 present the pre -restoration conditions data. The project is intended to provide numerous ecological benefits. While benefits such as habitat improvement and geomorphic stability are limited to the Site, reduced nutrient and sediment loading have farther reaching effects. The table below describes expected outcomes to water quality and ecological processes and provides project goals and objectives. The project goals and objectives were developed as part of the Mitigation Plan (Wildlands, 2017) considering the goals and objectives listed in the Neuse River RBRP plan and strive to maximize ecological and water quality uplift within the watershed.

The vegetation and stream success criteria for the Site were presented in the approved Mitigation Plan (Wildlands, 2017). 1.2.1 Vegetative 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). During the baseline monitoring 19 10-meter by 10-meter vegetation plots were established. The final vegetation success criteria at the end of MY7 are the survival of 210 planted stems per acre averaging 10 feet in height. Interim success criteria are the survival of 320 planted stems per acre at the end of MY3 and 260 planted stems per acre with an average stem height of 7 feet at the end of MY5. The MY2 vegetative survey was completed in September 2020. Vegetation monitoring resulted in an average stem density of 334 planted stems per acre, which is above the interim requirement of 320 stems per acre required at MY3 and approximately 44% less than the baseline density recorded (601 Buckwater Mitigation Site Monitoring Year 2 Annual Report - Final 1-2 planted stems per acre). There is an average of 8 stems per plot as compared to 15 stems per plot in MYO. A total of 9 of the 19 vegetation plots are on track to meet MY3 interim success criteria of 320 planted stems per acre and 15 of the 19 vegetation plots currently meet the final success criteria of 210 planted stems per acre. Refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern A high mortality rate of planted trees was observed between MY1 and MY2 (Figures 3a-3e Current Condition Plan View (CCPV)). The mortality rate can be attributed to competition from fescue and poor soils. A supplemental planting plan of 10.7 acres is presented in Section 1.2.7. A 1.4-acre area of low vegetative growth was noted along T5 (upstream of St. Mary's Rd) and T6 (Figure 3e CCPV and Table 6, Appendix 2). Grading during construction exposed rocky poor -quality subsoil near the surface. Soil amendments including a mixture of dolomitic lime, fertilizer, and humic acid, and a seed mix of herbaceous vegetation were applied to this area in August 2020. Amendments will continue to be applied throughout subsequent monitoring years, as necessary. An Adaptive Management Plan was submitted to the North Carolina Interagency Review Team (IRT) on December 7, 2020 to address the tree mortality and low vegetative growth areas seen during MY2. The document details contributing factors to the high mortality rate, specific trees and quantities to be planted, and a course of action to prevent future tree loss. 1.2.3 Stream Assessment Morphological surveys for MY2 were conducted in April 2020. All streams within the Site are stable and functioning as designed. Of the 36 cross -sections at the Site, 34 show little to no change in the bankfull area and width -to -depth ratio, and bank height ratios are less than 1.2. Pool cross -sections 26 and 28, on T5, show deviations from the as -built, but have stabilized since MY1. The changes in these two cross - sections occurred shortly after construction due to sediment deposition before vegetation was well established on the floodplain. The sediment deposition on the inside bend of the pools has created point bars, which is expected in a naturally meandering channel; therefore, no remedial actions are planned. Substrate measurements indicate the maintenance of coarser materials in the riffle reaches and finer particles in the pools. Longitudinal profile surveys are not required on the project unless visual inspection indicates reach wide vertical instability. Refer to Appendix 2 for the visual stability assessment table, CCPV maps, and stream photographs. Refer to Appendix 4 for the morphological data and plots. 1.2.4 Stream Areas of Concern Bank erosion was identified on Buckwater Creek Reach 7 between stations 146+00 and 151+00 during MY1. Stream bank repairs were conducted in April 2020 and are shown on Figure 3b (CCPV Map, and Stream Areas of Concern Photographs, Appendix 2). As discussed in Section 1.2.3 above, two pool cross -sections on T5 indicated point bar formation from MYO to MY1. Surveys show they are currently similar to MY1 results and no remedial action will be taken at this time. In -stream vegetation within some of the headwater channels caused sediment transport concerns and was therefore treated in August 2020 (Figure 3a-3e CCPV). Buckwater Mitigation Site Monitoring Year 2 Annual Report - Final 1-3 1.2.5 Hydrology Assessment By the end of MY7, two or more bankfull events must have occurred in separate years within the restoration reaches. Also, two geomorphically significant events must be documented during the monitoring period. Bankfull events were recorded on Buckwater Creek, T4, and T5 (upstream and downstream of St. Mary's Road) and T7. Multiple geomorphically significant events were recorded on all reaches except T7 during MY2. All reaches have partially fulfilled their bankfull and geomorphic requirements for the monitoring period. In addition, the presence of baseflow must be documented on restored intermittent reaches (T4A, T413, T6, T7A, T7, and T8) for a minimum of 30 consecutive days during a normal precipitation year. In -stream flow gages equipped with pressure transducers were installed to monitor continuity of baseflow. All reaches maintained baseflow as expected for intermittent streams with maximum consecutive days ranging from 70 to 294. Refer to Appendix 5 for hydrologic data. 1.2.6 Wetland Assessment Three groundwater gages were installed and monitored within the existing wetlands zones. All gages were installed at locations requested by NCDWR and were downloaded and maintained quarterly. The purpose of these gages is to assess potential effects to wetland hydrology from the construction of restored stream channels through these areas. The results of this monitoring are not tied to a success criterion. The measured hydroperiod ranged from 2.3% to 50.4% of the growing season consecutively. Results from groundwater gage 1 and 3 indicate areas along Buckwater Reach 4 and T1 Reach 2 are maintaining wetland conditions. However, groundwater gage 2 on Buckwater Reach 4 suggests slow recharge of the groundwater table after stream construction. Per the Mitigation Plan (Wildlands, 2017) selected wetlands will be redelineated during MY4 or MY5. Refer to Appendix 5 for wetland data. 1.2.7 Adaptive Management Plan In winter 2021, supplemental planting will occur in the low stem density areas (Figure 3.0 CCPV) ranging from a rate of 200 to 300 trees per acre. Areas with tall fescue will be sprayed around the planted trees after supplemental planting has occurred. The two low growth areas upstream of St. Mary's Road along T5 and T6 (Figure 3.0 CCPV) totaling 1.4 acres will continue to be tested and soil amendments will be applied accordingly. Refer to the Adaptive Management Plan document sent to the IRT on December 7, 2020 for more detail. 1.3 Monitoring Year 2 Summary Of the 19 vegetation plots, 9 are on track to meet the MY3 interim requirement of 320 planted stems per acre. Supplemental planting will occur in winter 2021. Wildlands will continue to monitor areas of poor herbaceous vegetation growth and will supplement as needed. In April 2020, the eroding banks along Buckwater Creek Reach 7 were repaired. In -stream vegetation removal was conducted on a few tributaries in August 2020. All streams within the Site are stable and functioning as designed. Pool cross - sections on T5 deviated from as -built dimensions shortly after construction due to point bar formation. Bankfull or geomorphically significant events were documented on all stream reaches during MY2. Greater than 30 days of consecutive flow were recorded on all intermittent reaches with flow gauges. 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 (Wildlands, 2017) available on DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Buckwater Mitigation Site 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 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 riffle cross -sections and monitored throughout the year. Hydrologic monitoring instrument installation and monitoring methods are in accordance with the United States Army Corps of Engineers standards (USACE, 2003). Vegetation monitoring protocols followed the Carolina Vegetation Survey-EEP Level 2 Protocol (Lee et al., 2008).
