The Project is located in Randolph County approximately 2.3 miles northwest of Level Cross, North Carolina (Figure 1). To access the Project head North on Randleman Road from city center for one mile and turn left on Hockett Dairy Road. Go about 1.3 miles before taking a farm access road to reach the project, on the right side. The coordinates are 35.9086 °N and -79.833 °W. Environmental Banc & Exchange, LLC (EBX), a wholly-owned subsidiary of Resource Environmental Solutions (RES), is pleased to provide this Monitoring Report for the Green Valley Farm II Riparian Buffer Mitigation Project (Project) as a full-delivery buffer mitigation project for the Division of Mitigation Services (DMS) (DMS #100111). This Project provides riparian buffer mitigation credits for unavoidable impacts due to development within the Randleman Lake Watershed (Figure 1). This Monitoring Report is in accordance with the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 and the Randleman Lake Water Supply Watershed Buffer Rule 15A NCAC 02B .0250. The conservation easement of the Green Valley Farm II Project totals approximately 7.19 acres and includes two unnamed tributaries that drain directly into Randleman Lake approximately 1,000 feet downstream of the Project. Land use within the Project parcel was primarily actively farmed row crops and newly planted riparian forest. The goal of the Project was to restore ecological function to the existing stream and riparian area by establishing appropriate plant communities while minimizing temporal and land disturbing impacts. Riparian area improvements help filter runoff from agricultural fields, thereby reducing nutrient and sediment loads to Project channels and the overall watershed. Restoration, of the Randleman Lake riparian area (as defined in 15A NCAC 02B .0250), results in a reduction of the water quality stressors affecting the Project. This Project is consistent with the management strategy for maintaining and protecting riparian areas in the Randleman Lake watershed. The easement is comprised of four sections, separated by two crossings and UT4. This Project surrounds an existing DMS project, Green Valley Farm Buffer Restoration Site (DMS # 95012, 2014-0073v1) that was closed out (Figure 2). The Green Valley II Project is composed of two stream channels: UT1 and UT4. Both of these reaches are outside of the actual easement boundaries but included in the previous Green Valley Farm Project. UT4 is a tributary to UT1, which then flows into Randleman Lake. UT1 is approximately 1,677 linear feet and is on the western side of the project. UT4 is approximately 590 linear feet and runs between the four easement segments. Stream identifications were verified by the DWR site visit on September 1, 2011, as well as a re-evaluation for UT4 on February 23, 2017. 1.2 Monitoring Protocol and Project Success Criteria Vegetation monitoring and visual assessments are to be conducted annually. Riparian area vegetation monitoring is based on the “Carolina Vegetation Survey-Ecosystem Enhancement Program Protocol for Recording Vegetation: Level 2 Plot Sampling Only Version 4.2”. Monitoring plots were installed a minimum of 100 meters squared in size and covered at least two percent of the planted mitigation area. These plots were randomly placed throughout the planted riparian restoration area and was representative of the riparian area restoration. The following data was recorded for all trees in the plots: species, height, Green Valley Farm II Mitigation Project 2 Baseline Monitoring Report Project #100111 June 2020 planting date (or volunteer), and grid location. All stems in plots were flagged with flagging tape. There are six fixed vegetation monitoring plots (Figure 2). Photos are to be taken at all vegetation plot origins each monitoring year and be provided in the annual reports. Visual inspections and photos are to be taken to ensure that restoration areas are being maintained and compliant. The measures of vegetative success for the Project are the survival of at least four native hardwood tree species, where no one species is greater than 50 percent of stems, at a density of at least 260 stems per acre at the end of Year 5. Native volunteer species may be included to meet the performance standards as determined by NC Division of Water Resources (DWR). A visual assessment of the conservation easement was performed each year to confirm: • No encroachment has occurred; • No invasive species in areas were invasive species were treated, • Diffuse flow is being maintained in the conservation easement areas; and there has not been any cutting, clearing, filling, grading, or similar activities that would negatively affect the functioning of the riparian area. Component/ Feature Monitoring Maintenance through project close-out Vegetation Annual vegetation monitoring Vegetation shall be maintained to ensure the health and vigor of the targeted plant community. Routine vegetation maintenance and repair activities may include supplemental planting, pruning, mulching, and fertilizing. Exotic invasive plant species shall be treated by mechanical and/or chemical methods. Any vegetation requiring herbicide application will be performed in accordance with NC Department of Agriculture (NCDA) rules and regulations. Vegetation maintenance activities will be documented and reported in annual monitoring reports. Vegetation maintenance will continue through the monitoring period. Invasive and Nuisance Vegetation Visual Assessment Invasive and noxious species will be monitored and treated so that none become dominant or alter the desired community structure of the Project. Locations of invasive and nuisance vegetation will be mapped. Project Boundary Visual Assessment Project boundaries shall be identified in the field to ensure clear distinction between the mitigation project and adjacent properties. Boundaries will be marked with signs identifying the property as a mitigation project and will include the name of the long- term steward and a contact number. Boundaries may be identified by fence, marker, bollard, post, tree-blazing, or other means as allowed by Project conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as-needed basis. Easement monitoring and staking/ signage maintenance will continue in perpetuity as a stewardship activity. Road Crossing Visual Assessment Road crossings within the Project may be maintained only as allowed by conservation easement or existing easement, deed restrictions, rights of way, or corridor agreements. Crossings in easement breaks are the responsibility of the landowner to maintain. 1.3 Project Components This Project generates approximately 175,509.615 ft2 (4.03 acres) of riparian restoration credits on existing cropland. These riparian mitigation credits generated service Randleman Lake buffer impacts within the Randleman Lake watershed. The total mitigation credits that the Green Valley Farm II Mitigation Project generates are summarized below and in Table 1. Green Valley Farm II Mitigation Project 3 Baseline Monitoring Report Project #100111 June 2020 1.4 Riparian Mitigation Approach Restoration efforts along UT1 and UT4 were accomplished through the planting, establishment, and protection of a hardwood forest community. The result was a riparian habitat that functions to mitigate nutrient and sediments inputs from the surrounding uplands. Traditional riparian restoration, as outlined in 15A NCAC 02B .0295 (n), was utilized. All riparian restoration activities took place within the 50-200’ riparian area along to UT1 and UT4 and was subject to crediting and ratios as outlined in the Consolidated Buffer Mitigation Rule. Mitigation ratios followed those provided in the Consolidated Buffer Mitigation Rule. Prior to the issuance of the RFP (#16-007703), RES received approval for restoration on February 27, 2012 and an update in March 24, 2017. RES received an email from DWR on May 13, 2019 that indicated that an updated site visit was not necessary. 1.5 Construction and As-Built Conditions Revegetation of the Site included treating invasive species and planting native hardwood bare root trees. Prior to planting, RES prepped the Site by spraying and ripping the easement. Piedmont Alluvial Forest is the target community type for the riparian restoration areas. The community is defined by Schafale (2012). The planting of bare root trees occurred in May 2020. Deviations from the initial planting plan were due to bare root availability. A list of the planted tree species can be found in Table 5. Additionally, a temporary and permanent seed mixture was applied in areas where row crops were present. Among a variety of seeds, the mixture also included black-eyed susan (Rudbeckia hirta) which is a perennial, pollinator species. 1.6 Baseline Monitoring Performance Monitoring of the six permanent vegetation plots was completed on May 6, 2020. Vegetation tables are in Appendix B and associated photos are in Appendix C. MY0 monitoring data indicates that all plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 971 to 1335 planted stems per acre with a mean of 1,039 planted stems per acre across all plots. A total of 13 species were documented within the plots. Volunteer species were not noted at baseline monitoring but are expected to establish in upcoming years. The average tree height observed was 1.6 feet. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project and no invasive species were observed. Additionally, there were no signs of encroachment or concentrated flow in the easement area.
