The Site is located approximately 3.5 miles southeast of Snow Camp and 6 miles north of Silk Hope in southern Alamance County near the Chatham County line. Project attributes are included in the following table. Table 1. Buffer Project Attributes Project Name Major Hill Hydrologic Unit Code 3030002050050 River Basin Cape Fear Geographic Location (Lat, Long) 35.873206,-79.360906 Site Protection Instrument (DB, PG) (2789, 896), (2514, 756), (3143, 270), (3150, 920) Total Credits (BMU) 402,837 Types of Credits Riparian Buffer Restoration, Enhancement, & Preservation Mitigation Plan Date Apr-18 Initial Planting Date Dec 2018-Jan 2019 Baseline Report Date Mar-19 MY I Report Date Nov-19 MY2 Report Date Jan-21 MY3 Report Date MY4 Report Date MY5 Report Date The Site drainage area is primarily composed of pasture, forest, agriculture land, and sparse residential property. Impervious surfaces account for less than five percent of the upstream land surface. Prior to construction, Site land use consisted of pasture, hayfields, disturbed forest, and agricultural land used for livestock grazing and hay production. Livestock had unrestricted access to Site streams, and stream banks were eroded vertically and laterally and received extensive sediment and nutrient inputs. Riparian zones in the upper reaches of UT 1 were primarily composed of herbaceous vegetation that was sparse and disturbed due to livestock grazing, bush hogging, and regular land -management activities. The downstream reaches of UT 1 and all of UT 3 were primarily wooded with livestock disturbance to stream channels. UT 2 was the lone tributary not subject to continuous, unrestricted livestock access. Riparian areas immediately adjacent to UT 2 were forested with a fence to protect this area from livestock access. The riparian areas were restored in concurrence with the Major Hill Stream and Wetland Mitigation Site (NC DMS Project ID 10015, SAW-2017-01472) and involved restoring riparian buffers adjacent to restored streams to help reduce non -point source contaminant discharges to downstream waters in the Haw River sub -watershed of Jordan Lake. All riparian areas were assessed by DWR (Katie Merritt and Sue Homewood) during an onsite visit February 2&, 2018 to determine viability for buffer mitigation. The Site is protected with a permanent conservation easement. Riparian restoration, enhancement, and preservation area widths adjacent to restored streams extend out to a maximum of 200 feet from the top of MY2 (2020) Riparian Buffer Monitoring Report (Project No. 100015) Appendix F: Page I Major Hill Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina January 2021 stream banks with a minimum width of 50 from the top of banks. Riparian buffer enhancement and preservation credits generated on this Site are allowed pursuant to 15A NCAC 02B .0295 (o). No riparian restoration areas that are less than 20 feet wide from Top of Banks are used to generate riparian buffer credit. Riparian buffer mitigation credit was not generated in areas that are generating wetland mitigation credit. 2.0 REGULATORY CONSIDERATIONS Credit determination for this Site follows the North Carolina consolidated buffer mitigation rule 15A NCAC 02B .0295, effective November 1, 2015 (see Table 2 on the following page and Figure A, Attachment 1). 3.0 RIPARIAN RESTORATION, ENHANCEMENT, & PRESERVATION PLAN This Site was also proposed as a stream and wetland mitigation project; therefore, restoration of riparian areas was accomplished through the goals and methods outlined by the Major Hill Stream and Wetland Mitigation Plan. All applicable federal, state, and local documentation, permits, and/or authorizations were acquired as part of implementing the above -mentioned mitigation plan. Primary goals focused on 1) improving water quality, 2) enhancing flood attenuation and hydrology, 3) improving aquatic resources, and 4) restoring riparian habitat. Completed mitigation provides floodplain connectivity, floodplain resistance, stream stability, sediment transport, surface and subsurface storage and retention, in -stream habitat, riparian habitat and structure, thermal regulation, floodplain biogeochemical processing, and pollutant filtration as well as remove sources of pollutants. The riparian area will be restored through the revegetation of native plant communities. 3.1 Riparian Area Restoration Activities 3.1.1 Site Preparation Soil grading occurred during stream restoration activities. Topsoils were stockpiled during construction activities and spread on the soil surface once critical subgrade was established. The replaced topsoil will serve as a viable growing medium for community restoration to provide nutrients and aid in the survival of planted species. Farm Pond Removal To complete the stream and wetland restoration activities and subsequent riparian buffer restoration, the removal of a small farm pond, —0.58 acres occurred. Stream, wetland and riparian area restoration within the abandoned pond included 1) notching the dam to dewater; 2) removal of the dam to the elevation of the adjacent floodplain; 3) excavating sediment that is unsuitable for channel bank construction; 4) backfilling areas of sediment removed with soil suitable for channel construction (as necessary); 5) excavation of the design channel, 6) stabilization of the channel with coir matting, seed, and mulch; and 7) installation of structures.

These areas are defined primarily as disturbed mixed hardwoods. Buffer credits sought in the enhancement area are allowed under 15A NCAC 02B .0295 (o)(6). The enhancement MY2 (2020) Riparian Buffer Monitoring Report (Project No. 100015) Appendix F: page 4 Major Hill Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina January 2021 area extends a maximum of 200 feet from the top of the bank with a minimum width of 20 from top of banks. A small portion of UT-3 is generating riparian buffer enhancement credit from only one side of the stream. Prior to construction, cattle had access to the entire area; however, the only access point was from the pasture on the northern side of the stream, the Parcel owned by Mr. Lamm. Once fencing was installed to prevent cattle access from Mr. Lamm's parcel to the stream, cattle will no longer be able to access the south side of the stream. This action will result in compliance with 15A NCAC 02B .0295 (o)(6), which states that the permanent exclusion of grazing livestock must be done such that the livestock are fenced out of the stream and its adjacent buffer. The southern parcel, which is not apart of the conservation easement, is owned by the Caviness family and is a single-family home. Cattle will not be grazing within their parcel post construction. 3.3 Riparian Buffer Preservation Activities Riparian buffer preservation includes permanently protecting existing riparian buffers from cutting, clearing, filling, grading, and any similar activities that would affect the functionality of the riparian buffer. Areas specified for Preservation at the Site, in accordance with 15A NCAC 02B .0295, are defined primarily as mixed hardwoods, with the number of high -value species above 200 per acre. They are areas where livestock were fenced out prior to construction with little or no historical livestock access. 3.4 Marsh Treatment Area A marsh treatment area was constructed to intercept surface waters draining through agricultural areas before discharging into UT1. The marsh treatment area is excluded from credit calculations. 4.0 ANNUAL MONITORING 4.1 Monitoring Eight vegetation monitoring plots (10-meter by 10-meter) were installed within the Site as per guidelines established in CVS-EEP Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008); this covers 3.4% of the area generating riparian buffer restoration credit. Vegetation monitoring will occur annually in the fall (between September and November), prior to the loss of leaves for a period of five monitoring years following planting. Parameters to be monitored include species composition and species density. Visual observations of the percent cover of shrub and herbaceous species will also be documented by photograph. In addition, inspections for beaver and other potential nuisance species will occur throughout the course of the monitoring period. The following table outlines riparian buffer monitoring for this project; monitoring parameter descriptions follow. Table 4. Riparian Buffer Monitoring Required Parameter Quantity Frequency Notes Eight (8) plots Vegetation will be monitored for five years or until Yes Vegetation located across all Annual performance standards are met. Visual monitoring of the restored buffer site will be done all five years. Analysis of vegetation zones. will be recorded using level 2 CVS Monitoring protocol. Yes Project NA Annual Locations of fence damage, vegetation damage, boundary Boundary encroachments, etc. will be mapped. MY2 (2020) Riparian Buffer Monitoring Report (Project No. 10001 S) Appendix F: page S Major Hill Stream and Wetland Restoration Site Restoration Systems, LLC Alamance County, North Carolina January 2021 4.2 Performance Standards Performance standards were established to verify that the vegetation component supports community elements necessary for forest development and the maintenance of diffuse flow through the riparian buffer in accordance with North Carolina Division of Water Resources Administrative Code 15A NCAC 0213.0295 (Mitigation Program Requirements for Protection and Maintenance of Riparian Buffers). Performance standards are dependent upon the density and growth of at least four native hardwood tree species where no one species is greater than 50% of the stems. After five years of monitoring, an average density of 260 woody stems per acre, including planted shrubs (silky dogwood and blueberry), must be surviving, and diffuse flow maintained. 15A NCAC 02b .0295 (2)(E) dictates that monitoring for planted stems would also include the health of planted stems. Level 2 CVS monitoring protocol requires the vigor, a determinant of health, of a monitored stem be recorded. If requested, RS will make available during the monitoring years, planted stem health, e.g. vigor. 4.3 Results and Discussion In early January 2020, a winter -time visual assessment of the site was performed, and it was determined that although Year 1 (2019) vegetation data, including random transects, showed a high density of trees, a light supplemental planting would help ensure the long-term success in several areas. On January 31, 2020, three areas that visually exhibited low stem density and/or poor vigor were supplementally planted (Figure 2, Appendix B). During the supplemental planting effort approximately 370 stems were planted across 1.20 acres (approximately 300 stems per acre). As the planting was designated for visual purposes and was not an effort to increase stem density data, no stems were planted within permanent vegetation plots. The following table lists species included in the supplemental planting list. Preparation included the application of 100 lbs of lime, 50 lbs of fertilizer, and 3 lbs of seed to stabilize bare areas (see Figure A for planting areas). Supplemental Planting Species List Species Number of Stems Tag Alder Alnus serrulata 20 Chinka in Castanea umila 20 Hackbe (Celtis occidentalis) 50 Hawthorn (Cratae us marshallii) 20 Crab Apple Malus an usti olia 50 Red Mulberry (Morus rubra) 100 Sycamore Platanus occidentalis 50 Shumard Oak ( uercus shumardii) 50 Total 370 Based on the number of stems counted, average densities were measured at 467 hardwood tree stems per acre (excluding livestakes, shrubs, pines, and vines) at year 2 (2020). In addition, all plots, including 3 temporary transects within the supplemental planting areas, met success criteria. The following Table 5 summarizes riparian buffer success criteria and Table 6 summarizes all permanent vegetation plot data by species, plot, and year.
