Watershed Investments NC (WINC), the sponsor, originally planted the site in November -December 2016. The site encompasses 6.15 acres of land along Neville Creek in Orange County North Carolina and is broken into two tracts separated by Neville Creek (See Figure 1 for a map of the site). Site activities consisted of approximately 5.04 acres of riparian restoration and approximately 0.94 acres of riparian preservation. An additional 0.17 acres of Tract 1 is included in the project easement area but is outside the rule -defined riparian buffer zone and, consequently, is not included for either riparian buffer mitigation or nutrient offset credit generation. Year 3 (2019) monitoring data was collected on October 11, 2019 by Axiom Environmental (See Attachmentl). While average density of planted stems per acre were above success criteria of 260 planted stems, in their review of the report, NC Division of Water Resources (DWR) staff raised concerns over limited plant growth at both tracts of the Site (See NC DWR Email in Attachment 2) and prompted a visit to review the site. Staff from Watershed Investments (Mike Herrmann), Axiom Environmental (Phillip Perkinson) accompanied Katie Merritt (DWR) on a visit to the Site on June 111h, 2020 to review plant growth and discuss options for corrective measures. In their visit, deer browsing, competition from existing fescue, and poor soils were all sited as potential causes for limited tree growth in some areas of both tracts. The prevalence of these causes varied between Tract 1 and Tract 2 but raised concerns over planting success at some areas within the Site. No signs of easement encroachment were observed during the visit. The following is a brief summary of observations made of the two tracts during the site visit. Tract 1- Planted stem growth was observed to be meeting success criteria throughout the majority of the mitigation area and numerous natural volunteer plants were observed. Limited plant growth was observed, however, both within Plot 7 and its immediate surrounding area (See Figure 1). In the Plot 7 area dense fescue was established. Additionally, the plot's planted stem viability was the lowest of all the plots (283 stems/acre). Based on field observation, the area of suppressed growth is estimated to be 0.30 acres. Tract 2 — Both plant diversity and growth were limited in most of the easement area except for the area within monitoring Plot #2. Potentially causes for these problems were suggested to be poor soil and plant herbivory. The area affected is shown in Figure 1 and is approximately 1.20 acres. In response to concerns found in the annual monitoring reports and observed during the visit, the following adaptive measures are proposed to, increase planted tree density, provide plant diversity, and address competition from herbaceous plants. Adpative Management Plan Herbaceous competition from fescue was observed to be a likely cause of stunted plant growth on Tract 1. On this tract, herbicide will be used to control fescue. Chemicals labeled safe for use in riparian zones and in aquatic environments will be mixed and applied at rates labeled for treatment of fescue. Precautions will be taken to avoid collateral damage to desirable vegetation (both planted and volunteer). Pesticide application will be conducted by a licensed application specialist and logs will be available upon request. Fescue application will be scheduled soon after approval of this adaptive management plan. Soil testing of Tract 2 is being undertaken to determine whether the site needs soil amendments prior to the container planting. Soil amendment will occur as needed based on soil testing. Possible amendments to the soil include the use of lime to lower acidity and/or fertilization to improve low soil nutrients (e.g., phosphorus, or potassium) while being careful not to over fertilize. Fertility in Tract 1 was not observed to be a problem. To increase planted stem density, planting one -gallon container plants will occur on both tracts 1 and 2. On Tract 2,150 native hardwood species listed in Table 1 will be planted at a density of approximately 100 stems per acre to fill in areas with low planted stem growth or stunted growth. This density, when combined with existing successful plants, should solidify the likelihood that plantings at the site will meet success criteria defined in the Mitigation Banking Instrument at the site close-out. To assess planting needs, Tract 2 is separated into 2 sides based on topography and existing tree growth. Results from soil tests and existing tree locations on each side will be used to determine where container plants are needed to supplement sparse areas of existing tree growth. Soil amendments will be based on soil test findings. For Tract 1, where the area is smaller, approximately 50 trees will be planted using a more uniform 16-foot spacing. Of the Table 1 species, Acer rubrum (Red Maple) will not be planted on Tract 1 and only used on Tract 2. Planting of both tracts will occur in the Fall/Winter of 2020/2021 and observed over Year 5 of the monitoring period. Due to their more developed root system, the container plants will be better enabled to overcome herbivory that is suspected to be affecting the site. In addition, to discourage herbivory, a deer repellent will be applied at least once to the plants on Tract 2 in the spring of 2021 when trees are in the early budding stage. A non -toxic repellent safe for wildlife will be used. Table 1. Proposed one -gallon tree species (Note: Species availability may result in the substitution of regionally appropriate native species.)

Year 3 Neville Monitoring Report YEAR 3 (2019) MONITORING REPORT Neville Farms Buffer and Nutrient Offset Bank Parcel (Phase 1 & Phase 2) Jordan Lake Nutrient Strategy - Upper New Hope Subwatershed Orange County, NC DWR# 2015-0636 October, 2019 Prepared by: Axiom Environmental, Inc. 218 Snow Avenue Raleigh, NC 27603 Phone: 919.215.1693 Prepared for: Watershed Investments NC, LLC 1630 Weatherford Circle Raleigh, NC 27604 Phone: 919.533.9195 WATERSHED Investments EXECUTIVE SUMMARY Watershed Investments NC (Sponsor) is pleased to provide the NC Division of Water Resources (DWR) this Year 3 (2019) Annual Monitoring Report for the Neville Farms Bank Parcel (Site). The purpose of this project is to generate Jordan Lake riparian buffer restoration and preservation mitigation credits as well as nutrient offset credits. The Neville Farms Bank Parcel is included in the Neville Farms Mitigation Banking Instrument (MBI) for Riparian Buffer Mitigation and Nutrient Offset Credits signed between Watershed Investments NC, LLC and the NC Division of Water Resources (DWR) and effective on January 291h, 2016. The MBI is in accordance with 15A NCAC 02B .0295 (Temporary Consolidated Buffer Mitigation Rule, effective October 24, 2014) and 15A NCAC 02B .0240 (Nutrient Offset Payments Rule). The Site is located approximately 3 miles southwest of Chapel Hill, NC and one mile upstream of University Lake. Surface water drainage features at the Site feed into the Upper New Hope subwatershed of Jordan Lake. The Site is located in the Cape Fear River Basin 14-digit United States Geological Survey (USGS) Cataloging Unit 03030002060070 of the South Atlantic/Gulf Region (North Carolina Division of Water Quality [NCDWQ] Sub -basin Number 03-06-06). Project restoration activities and planting were completed in November -December 2016. Completed project activities, reporting history, completion dates, project contacts, and project attributes are summarized in Tables 1-4 (Appendix A). The site encompasses 6.15 acres of land along Neville Creek, which is a tributary to University Lake south of Chapel Hill in Orange County North Carolina. Site activities consisted of approximately 5.04 acres of riparian restoration and approximately 0.94 acres of riparian preservation. An additional 0.17 acres of Tract 1 is included in the project easement area but is outside the rule -defined riparian buffer zone and, consequently, not included for either riparian buffer mitigation or nutrient offset credit generation. The Site is comprised of two separate tracts owned by two different land owners and is being mitigated in two phases. Phase 1 is comprised of Tract I and Phase 2 is comprised of Tract 2. Each phase/tract has its own credit release schedule for milestones met in accordance with the Neville Farms Mitigation Banking Instrument (MBI). Though the tracts are adjacent, the division of the Site was necessary based on land use, land planning, and project crediting. Moving forward; however, project activities for both Tracts are proceeding on the same schedule. Tract information is as follows. Tract Acreage Location Tract 1 (Gambill/Neville Property) 4.31 ac. Main project area located on the north side of Neville Creek and accessible from Old Greensboro Highway Tract 2 (McGee Property) 1.84 ac. Area south of Neville Creek and accessible from Stansbury Road Orange County is the delegated authority by the NC Environmental Management Commission to conduct determinations on whether drainage features in their jurisdiction are surface waters and subject to the buffer rules of the State found in 15A NCAC 02B .0267 (Protection of Existing Riparian Buffers). Orange County i Neville Farms Year 2 (2018) Annual Monitoring Report (Phases 1 &2) Watershed Investments NC Planning and Inspections assessed the Site and provided their determination on February 9th, 2015 that the surface water features on the Site are subject to the Rule (Appendix C). The project has restored and preserved forest adjacent to surface water features to reduce nutrients that flow into Neville Creek, University Lake, and ultimately Jordan Lake. The project will have ancillary benefits that include reducing sediment runoff, reducing nutrients to streams through agricultural runoff, and thus, improving aquatic and terrestrial habitat. Any nutrient offset or riparian buffer mitigation generated from this Bank Parcel may offset impacts from development, both existing and proposed, within the Upper New Hope Subwatershed of Jordan Lake, as verified by DWR staff onsite and in a letter dated April 6, 2015 (Appendix E). At the request of NC DWR, one (1) additional permanent vegetation plot was installed in the Zone C Restoration area of Tract 1 during year 1 annual monitoring for a total of five (5) permanent vegetation plots in Tract 1 and two (2) permanent vegetation plots in Tract 2. During Year 1 (2017), mowing occurred to reduce herbaceous competition of planted trees. Year 3 (2019) data was collected on October 11, 2019 by Axiom Environmental and derived an average density of 451 planted stems per acre (excluding livestakes). In addition, all seven vegetation plots were well above success criteria of 260 planted stems per acre. No problem areas were observed in Year 3 (2019). ii Neville Farms Year 2 (2018) Annual Monitoring Report (Phases 1 &2) Watershed Investments NC Table of Contents EXECUTIVESUMMARY............................................................................................................................................... 1 1.0 PROJECT MONITORING AND PERFORMANCE STANDARDS.......................................................................... 1 1.1 Project Monitoring Plan..................................................................................................................................1 1.2 Success Criteria.................................................................................................................................................1 2.0 MITIGATION POTENTIAL.................................................................................................................................... 2 3.0 ADAPTIVE MANAGEMENT PLAN .......................... 4.0 REFERENCES ......................... 2 ........................... 3 APPENDICES APPENDIX A.

CVS Data Summary Table Permanent Photo Points Vegetation Plot Photographs Neville Farms Year 3 (2019) Annual Monitoring Report (Phases 1 &2) Watershed Investments NC 1.0 PROJECT MONITORING AND PERFORMANCE STANDARDS 1.1 Project Monitoring Plan Riparian vegetation monitoring for Phase 1 and Phase 2 will be based on the CVS Level 1-2 Pmtocol for Recording Vegetation, Version 4.2 (Lee et al. 2008). Annual vegetation monitoring will occur each year during the fall season with the first year for each Phase occurring at least 5 months after initial planting of the Tract/s. Vegetation monitoring plots measure 0.0247 acre in size and cover 2% of the planted area. Accordingly, four (4) permanent vegetative plots will be used to monitor Tract 1 and two (2) permanent vegetative plots will be used to monitor Tract 2. At the request of NC DWR, one (1) additional permanent vegetation plot was installed in the Zone C Restoration area of Tract 1 during year 1 annual monitoring for a total of five (5) permanent vegetation plots in Tract 1 and two (2) permanent vegetation plots in Tract 2 (Figure 2, Appendix A). A reference photo will be taken from the southwestern corner of each plot. All planted stems in the plots will be marked with flagging tape and recorded. Data collected will include species, height, planting type (planted stem or volunteer), and grid location. Year 3 (2019) CVS data was collected on October 11, 2019 by Axiom Environmental and derived an average density of 450 planted stems per acre (excluding livestakes) (Table 7, Appendix B). Planted stems throughout the site were generally vigorous with an average planted stem height of 2.65 feet (81.5cm). The Sponsor shall submit to DWR an annual monitoring report for each phase, no later than December 31 of each year for five consecutive years. Reports will document the success of the vegetation and any maintenance, supplemental planting, or encroachment within the easement areas. As planting and the monitoring for both Phase 1 and 2 occurred on the same schedule, WINC intends to submit one Monitoring Report each year for at least 5 years to document the above requirements for both phases. All Monitoring Reports shall reflect the Phase for which it is being submitted. Monitoring bonds shall be renewed with confirmation of renewal provided to DWR with each annual monitoring report for each phase. DWR reserves the right to alter the credit release schedule if monitoring reports are submitted without proof of bond renewals. Invasive and noxious species will be monitored annually and controlled as needed so that none become dominant or alter the desired community structure of the site. Year 2 maintenance and mitigation activities occurring at the Site included herbicide treatment on local areas of Japanese Stiltgrass (Microstegium vimineum) and Autumn Olive (Eleagnus umbellata) at Tract 2. These treatments were conducted on May 25, 2018 with a follow up on August 31, 2018. An aquatic -safe glyphosate (AquaNeat) herbicide was applied by a licensed Pesticide Applicator to control the invasive vegetation. Additionally, the conservation easement associated with the project was transferred to Unique Places to Save on July 26, 2018. This transfer fulfilled the property disposition and long-term management requirements of the Neville Farms MBI. Easement boundaries were checked at the time of CVS data collection, there were no signs of encroachment. 1.2 Success Criteria Pursuant to criteria found in the Temporary Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 and Neville Farms MBI, vegetative success for the Site will require the survival of at least 260 planted trees per 1 Neville Farms Year 3 (2019) Annual Monitoring Report (Phases 1 &2) Watershed Investments NC acre at the end of Year 5 based on monitoring data compiled for the site and site visits by the DWR. Natural recruits will not count towards annual achievement of performance standards; however, they may be taken into account during review by the NC DWR. Recruitment of volunteer species in the floodplain is anticipated due to adjacent forests that exist upstream and on the stream bank. 2.0 MITIGATION POTENTIAL As noted in the Neville Farms MBI, buffer credit determination is subject to the Temporary Buffer Rule 15A NCAC 02B .0295(h) and (i). Figure 3 (Appendix A) identifies the riparian areas and credit types for Phase 1 and Phase 2. In accordance with Rule 15A NCAC 02B .0295, the width of the buffer/nutrient credit generation area begins at the most landward limit of the top of bank or the rooted herbaceous vegetation and extends landward to a maximum distance of 200 feet. Nutrient offsets are not being generated within the areas described as Preservation. Preservation areas meet the requirements described in .0295 (m) (2) (D) — Preservation of Buffers on Subject Streams. Restoration areas meet the requirements of .0295(i) — Riparian Restoration or Enhancement. Nutrient Offset credits are consistent with rules 15A NCAC 02B .024. The following is a summary of the Jordan Lake riparian buffer credits and nutrient offset credit calculations for Phase 1 and Phase 2 of the Site. Detailed credit calculations are included in Tables 1A-1D (Appendix A). Phase 1 (Tract 1� • 0.40 acres Riparian Buffer Preservation = 1742.4 square feet of credit • 3.74 acres Nutrient Offset = 7220.59 lbs-N delivered and 424.90 lbs-P delivered) Phase 2 (Tract 2) • 1.30 acres Riparian Buffer Restoration = 55,321.2 square feet (ft2) of credit • 0.54 acres Riparian Buffer Preservation = 2330.50 square feet (ft2) of credit As indicated in the Site's MBI, credits generated from riparian buffer restoration activities can be converted and transferred from buffer credits to nutrient offset credits with Division approval and from nutrient offset credits to buffer credits. However, when converting from nutrient offsets to buffer, all applicable ratios and percentages of full credit will apply according to 15A NCAC 02B .0295. Neville Farms' Nutrient Offset and Riparian Buffer credits will not be debited within the same area (not stacked). The Neville Farms Bank will service impacts within the Upper New Hope Subwatershed of Jordan Lake. 3.0 ADAPTIVE MANAGEMENT PLAN In the event that the Site, or a specific component of the Site, fails to achieve the defined performance standards, WINC will develop necessary adaptive management plans and/or implement appropriate remedial actions for the Site in coordination with DWR. Remedial actions will be designed to achieve the performance standards specified previously, and will include identification of the causes of failure, remedial design approach, work schedule, and monitoring criteria that will take into account physical and climatic conditions. 2 Neville Farms Year 3 (2019) Annual Monitoring Report (Phases 1 &2) Watershed Investments NC 4.0 REFERENCES Lee, M.T., RK.

NC DWR Comments on Year 3 Neville Monitoring Report mherrmann@watershedinvestmentsnc.net From: Merritt, Katie <katie.merritt@ncdenr.gov> Sent: Monday, January 13, 2020 11:09 AM To: mherrmann@watershedinvestmentsnc.net Subject: RE: [External] FW: Watershed Investments I Continuation Certificate [-Restricted-] Hey Mike, I just finished the monitoring report on Friday, and I do have some concerns regarding the health of the trees recorded in the monitoring report, despite the vigor rating. This is Year 3, and upon my review of the report, >25% of the stems are smaller this year when comparing the data from 2018. There is nothing in the report that indicates a problem was observed, but I presume there is an explanation? Some stems were >15cm less than last year. Also observed, is that >70% of the stems recorded are <3 feet tall for this Year. Of the stems that are actually greater than 3', they are only Sycamore, Green Ash and 1 Oak. The pictures provided in the report show lots of weeds and very few trees, and the easement boundary doesn't look well marked in PP 1 and PP2. As a result, I am very concerned that this site is not on trajectory to meeting performance by year 5 considering the height of the trees is alarmingly small. By Year 3, a majority of your planted stems should be well over 3', and in comparison to most bank site's Year 3 monitoring data, yours is underperforming. Upon allowing a bond reduction, DWR will need to see the site in late Spring 2020 to determine how representative the plot data is of the entire site as a whole. It will be at this site visit, that DWR will assess the vegetation condition and determine if a remediation plan will be required. Therefore, DWR will not be authorizing a bond reduction at this time. You will need to secure a continuation certificate for the bond amount currently in place at $44,000. Additionally, only a 5% credit release will be issued upon securing the continuation certificate. When I have visited the site in Spring 2020, 1 will determine if the remaining 5% credit release is warranted at that time.
