The Parcel shall be planned and designed according to the UMBI, 15A NCAC 02B .0240, and the Consolidated Buffer Mitigation Rule 15A NCAC 0213.0295 which became effective on November 1, 2015. The BPDP has also been designed in concurrence with the Cane Creek Stream and Wetland Umbrella Mitigation Bank (SAW# 2016-00219). The Mitigation Plan for the South Fork Stream and Wetland Mitigation Site has been submitted to the Interagency Review Team. The project encompasses land along unnamed tributaries to South Fork Cane Creek in Chatham County, NC. The primary purpose of the Bank is to provide riparian buffer mitigation credits to compensate for unavoidable buffer impacts in the 03030002 Hydrologic Unit Code (HUC) of the Cape Fear River Basin, within the Haw River Sub -watershed of the Jordan Lake Watershed. The Bank may also provide nutrient offset credits for stormwater requirements with new and existing development requiring nutrient offsets within the Haw River Sub -watershed of the Jordan Lake Watershed. The bank service area is depicted in Figure 1. 1.0 Project Location and Description 1.1 Introduction This Parcel is being proposed to provide stream and wetland mitigation through the creation of a Stream and Wetland Mitigation Bank Site on unnamed tributaries to South Fork Cane Creek as well as nutrient offset and buffer mitigation through the creation of a Buffer & Nutrient Offset Bank. Riparian restoration activities deemed suitable for riparian buffer mitigation will generate 444,747.60 ft' riparian buffer mitigation credits. Riparian restoration activities deemed suitable for nutrient offsets on this Parcel could generate 2,249.36 lbs. -Nitrogen per acre and 143.81 lbs. -Phosphorus per acre (with a delivery factor of 71% and 67% respectively) if converted from riparian buffer mitigation credits. For purposes of the South Fork Buffer and Nutrient Offset Bank, the Parcel involves restoring riparian buffers and other riparian areas adjacent to mitigated streams onsite in order to help reduce non -point source contaminant discharges to downstream waters in the Jordan Lake Watershed within the Cape Fear River Basin. Approximately 18.13 acres will be protected with a permanent conservation easement. Out of the 18.13 acres, 15.30 acres will be mitigated to generate Jordan Lake riparian buffer credit. Out of the 15.30 acres, 5.48 acres qualify for either riparian buffer mitigation credit or nutrient offset credit, but not both. In general, riparian areas that are restored, enhanced or preserved for buffer or nutrient offset credits, will be a minimum of 30 feet from the top of stream banks and out to a maximum of 100 feet. The NC Division of Water Resources (DWR) performed an onsite Site Viability for Buffer Mitigation and Nutrient Offset on August 9, 2017. The correspondence related to the site visit is attached in the Appendix and dated April 15 and 16, 2017. South Fork Mitigation Site HUC 03030002 — BPDP 1.2 Parcel Location The Cane Creek Umbrella Mitigation Bank Sites are located in Chatham and Alamance County near the Town of Snow Camp, NC. The site described in this bank parcel development plan is the South Fork Bank Parcel (36° 10' 9.48" N and 78° 55'49.44" W) which is located in Chatham County within the Cape Fear River Basin Hydrologic Unit 03030002050050 (Cane Creek) and the North Carolina Division of Water Resources (NCDWR) Subbasin 03-06-04 (Figure 2).

Table 1. Project Features Descriptions — South Fork BPDP Feature Name** Feature ID from DWR Assessments Stream Type Buffer Credit Nutrient Offset Viable Viable SF4A SF Perennial Yes Yes* UT1 UT1 Intermittent Yes Yes UT2 UT2 Intermittent/Perennial Yes Yes UT4 UT4 Perennial Yes Yes* * Nutrient Offset is viable in non forested pasture areas only ** No credits are being requested on UT3 and UT5 referenced in DWR correspondence. Subjectivity calls for the features were determined by DWR in correspondence dated August 15, 2017 using the 1:24,000 scale quadrangle topographic map prepared by USGS and the most recent printed version of the soil survey map prepared by NRCS. SF4A, UT1 and UT2 were determined to be subject to the Jordan Lake Buffer Protection Rule 15A NCAC 02B .0267. UT4 is not subject to the Jordan Lake Buffer Protection Rules. The results documented in the Site Viability Letter from DWR dated April 16, 2017 indicated that SF4A, UT1, UT2 and UT4 are viable for riparian restoration and suitable for buffer mitigation. SF4A, UT1, UT2, and UT4 are also viable for nutrient offset credits in non -forested pasture areas. These areas are currently being restored for riparian buffer credit, but may be converted to nutrient offset credit pursuant to 15A NCAC 02B .0295 and the MBI. Written approval must be granted by DWR prior to any conversion and transfer of credits. Photos showing historic site conditions and current site conditions (as of August 2017) of the Parcel are provided in the appendix. Site conditions have not changed since the DWR 2017 viability letter and August 2017 site photos. South Fork Mitigation Site HUC 03030002 — BPDP 2.2 Parcel Soils The largely forested watersheds with low rolling topography result in relatively low sediment supply. The bed material in the streams on this site is small to medium gravel and sand that is derived from highly weathered parent material. Soil mapping units are based on the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) Soil Survey for Chatham County. Soil types within the study area were mapped with the NRCS Web Soil Survey and are described below in Table 2. The South Fork project area is dominated by Chewacla loams. This soil frequently floods and is poorly drained, resulting in frequent occurrence of wetlands. The 1937 Soils Survey Map is provided in Figure 4. Table 2: Project Soil Types and Descriptions — South Fork BPDP Soil Name Location Description Chewacla and Wehadkee soils consist of nearly level, Chewacla and Mapped along the floodplain of very deep, poorly and somewhat poorly drained soils.

Source: Chatham County Soil Survey, USDA-NRCS, http://efotg.nres.usda.gov 2.3 Existing Vegetative Communities The cattle pastures on the site are dominated by fescue grasses (Festuca spp.) and broomsedge (Andropogon virginicus). Much of the riparian areas on the site are wooded; however, cattle have access to all of the streams except the downstream portion of SF4A, as noted in the DWR Site Viability letter. Vegetation in the wooded areas is primarily hardwood species including white oak (Quercus alba), red oak (Quercus rubra), willow oak (Quercus phellos), tulip poplar (Liriodendron tulipifera), sweetgum (Liquidambarstyraciflua), red maple (Acer rubrum), southern red oak (Quercus falcata), and American elm (Ulmus americana). Vegetation within the riparian areas along the right bank of SF4A, as noted in South Fork Mitigation Site klW HUC 03030002 — BPDP the DWR Site Viability letter, lack a healthy divers understory and therefore require supplemental plantings to be viable for generating buffer credits. 2.4 Threatened and Endangered Species Wildlands utilized the US Fish and Wildlife Service (USFWS) and NC Natural Heritage Program (NHP) databases to search for federally listed threatened and endangered plant and animal species in Chatham County, NC. Two animal and one plant species identified as threatened or endangered are currently listed in Chatham County (Table 3). Table 3: Listed Threatened and Endangered Species in Durham County, NC — South Fork BPDP Species Federal Status Common Name Scientific Name Red -cockaded woodpecker Picoides borealis Endangered Cape Fear shiner Notropis mekistocholas Endangered Harperella Ptilimnium nodosum Endangered A letter was sent to the USFWS on April 1, 2016, requesting a review of the project and comment on potential effects on endangered species or other resources. The USFWS responded on July 22, 2016, and stated the "proposed action is not likely to adversely affect any federally listed endangered or threatened species, their formally designated critical habitat or species currently proposed for listing under the Act..." USFWS also stated a concern for potential sediment loss during the stream and wetland mitigation construction period. These concerns are addressed in Section 3.0 below. All correspondence with USFWS is included in Appendix 5. A pedestrian survey of the project area was performed on November 7, 2016. No suitable habitat and/or individually federally listed species were identified in the project area. 2.5 Cultural Resources The site is not located near any sites listed on the National Register with the State Historic Preservation Office (SHPO). A letter was sent to the SHPO on April 1, 2016, requesting a review of the project and comment on potential effects on archeological and cultural resources. SHPO responded on July 1, 2016 stating that they are not aware of any historic resources that would be affected by the project. 2.6 Environmental Issues An EDR Radius Map Report with Geocheck was ordered for the Parcel through Environmental Data Resources, Inc. on April 7, 2016. The target property and the adjacent properties are not listed in any of the Federal, State, or Tribal environmental databases searched by EDR. There were no known or potential hazardous waste sites identified within one mile of the Parcel. The Executive Summary of the EDR report is included in the Appendix. 3.0 Riparian Restoration, Enhancement and Preservation Plan Developing the Parcel for mitigation will require converting existing agriculture land use practices adjacent to streams into riparian forest. The mitigated riparian areas, which includes the 50 -foot -wide Jordan Lake riparian buffers, will involve replanting appropriate native tree species along the project corridors. Vegetation management and herbicide applications may be needed during the first year of tree establishment in the restoration areas to prevent establishment of invasive species that could out South Fork Mitigation Site HUC 03030002 — BPDP 4 compete the planted native species. More detailed descriptions of the proposed restoration activity follow in Sections 3.1-3.4 and are shown on Figure 5. This site is also being proposed as a stream and wetland mitigation bank; therefore, restoration of riparian areas will be accomplished through the goals and methods outlined by the Cane Creek Umbrella Mitigation Banking Instrument — South Fork Stream Mitigation Plan (USACE # 2016-00219) and the South Fork Riparian Buffer & Nutrient Offset Mitigation Banking Instrument. All applicable federal, state, and local documentation, permits, and/or authorizations will be acquired as part of implementing the above-mentioned mitigation plan and will be provided to DWR as part of the As Built Report including Section 401, Section 404 and Sediment and Erosion Control permits. All riparian restoration activities will commence in concurrence with the stream mitigation activities and not before. Therefore, the mitigation area where riparian restoration is being performed may be altered slightly depending on the implementation of the South Fork Stream Mitigation Plan for the Cane Creek Umbrella Mitigation Bank. 3.1 Parcel Preparation The current land uses adjacent to the streams proposed for buffer restoration are primarily non - forested crops. Areas slated for buffer restoration will require site preparation that will include select herbicide treatments or limited mechanical clearing to remove undesirable underbrush or invasive species. Diffuse flow will be maintained in the buffers. 3.2 Riparian Area Restoration Activities The revegetation plan for the entire buffer restoration area will include permanent seeding, planting bare root trees, live stakes, and herbaceous plugs and controlling invasive species growth. The specific species composition to be planted was selected based on the community type, observation of occurrence of species in riparian buffers adjacent to the Site, and best professional judgement on species establishment and anticipated Site conditions in the early years following project implementation. Species chosen for the planting plan are listed on Sheet 2.0 of the preliminary stream mitigation design plans located in the Appendix and in Table 4. The plans also contain information on planting zones on Sheets 2.1. Table 4: Selected Tree Species Appropriate for Buffer Restoration — South Fork BPDP Species Common Name Ulmus americana American Elm Celtis occidentalis Hackberry Quercus pagoda Cherrybark Oak Liriodendron tulipifera Tulip Poplar Quercus phellos Willow Oak Plantus occidentalis Sycamore Betula nigra River Birch Quercus michauxii Swamp Chestnut Oak Fraxinus pennsylvanica Green Ash South Fork Mitigation Site HUC 03030002 — BPDP Trees will be planted at a density sufficient to meet the performance standards outlined in the Rule 15A NCAC 02B .0295 of 260 trees per acre at the end of five years. No one tree species will be greater than 50% of the established stems. An appropriate seed mix will also be applied to provide temporary ground cover for soil stabilization and reduction of sediment loss during rain events in areas disturbed by stream construction, as necessary. This will be followed by an appropriate permanent seed mixture. 3.3 Riparian Area Enhancement Activities The revegetation plan for the buffer enhancement areas under NCAC 02B .0295(n) will include planting supplemental bare root trees and controlling invasive species growth. The tree species to be planted are listed in Table 4. For buffer enhancement areas under NCAC 02B .0295(o), cattle exclusion, planting isn't anticipated to be needed except where required in the stream mitigation plan. A seed mix will be applied where cattle have caused bare soils and removed all vegetation and cattle will be fenced out of the easement area. The proposed fencing boundary is shown on Figure 5. 3.4 Riparian Area Preservation Activities There will be no parcel preparation work done in the buffer preservation areas, as allowed under 15A NCAC 02B .0295(o). The preservation area will be protected in perpetuity under a conservation easement. Site preparation and planting on the restoration and enhancement areas is scheduled to begin in January 2019. 4.0 Monitoring and Maintenance Plan 4.1 Monitoring Protocol Permanent vegetation monitoring plots will be installed and evaluated within the buffer restoration and/or nutrient offset areas to measure the survival of the planted trees. There may be additional plots within the riparian buffer that are measuring the success of the riparian areas as part of the stream and wetland mitigation bank, but only the plots measuring the success of the riparian buffer credit will be provided in the monitoring reports. The plots will be randomly placed throughout the planted riparian areas and will be representative of the entire top of bank back one -hundred feet, more or less. A total of 5 plots will be established within the buffer restoration credit generation area. The number of monitoring quadrants required is based on the USACE Wilmington District monitoring guidance documents. The size of individual quadrants will be 100 square meters for woody tree species. Vegetation assessments will be conducted following the Carolina Vegetation Survey (CVS) Level 2 Protocol for Recording Vegetation (2008). A reference photo will be taken from the southwestern corner of each of the 5 plots. Photos will be taken from all photo points each monitoring year and provided in the annual reports. All planted stems will be marked with flagging tape and recorded. Planting is scheduled for January 2019. The first annual monitoring activities will commence at the end of the first growing season, at least five months after planting has been completed and no earlier than the fall season. Species composition, height, and survival rates will be evaluated on an annual basis by plot. The total number of volunteer woody stems will also be documented and reported. The measures of vegetative success for the Parcel will be the survival of at least 4 native hardwood tree species, where no one species is greater than 50% of the established stems, established at a density of at least 260 South Fork Mitigation Site HUC 03030002 — BPDP planted trees per acre at the end of Year 5. Appropriate native volunteer species may be included to meet the performance standards with DWR approval. A visual assessment of the cattle exclusion and preservation areas within the conservation easement will also be performed each year to confirm: • Fencing is in good condition throughout the site; • no cattle access within the conservation easement area; • no encroachment has occurred; • diffuse flow is being maintained in the conservations easement area; and • there has not been any cutting, clearing, filling, grading, or similar activities that would negatively affect the functioning of the buffer. Any issues identified during the visual assessment of the cattle exclusion and preservation areas will be photographed and mapped as part of the annual monitoring report with remedial efforts proposed or documented. The Sponsor shall submit the annual monitoring report to DWR by December 31St of each year for five consecutive years and will follow the terms and conditions of the MBI. 4.2 Parcel Maintenance Adaptive measures will be developed, or appropriate remedial actions will be implemented in the event that the Parcel or a specific component of the Parcel fails to achieve the success criteria outlined in Section 4.1. Site maintenance will be performed to correct any identified problems on the Parcel that have a high likelihood of affecting project success. Such items include, but are not limited to, excess tree mortality caused by fire, flooding, drought, or insects. Any actions implemented will be designed to achieve the success criteria and will include a work schedule and updated monitoring criteria. Any parcel maintenance performed will be included in the monitoring report for that year. A rigorous herbicide schedule will need to be implemented in the first few years of tree establishment in the restoration areas to prevent establishment of invasive species that may attempt to out -compete the planted native vegetation. The only herbicides used on the Parcel will be aquatic approved herbicides that will be applied in accordance with North Carolina Department of Agriculture rules and regulations. The easement boundary will be checked annually as part of monitoring activities and the conditions as well as any maintenance performed will be reported in the annual monitoring reports to NC DWR. If mowing is deemed necessary by the Sponsor during the monitoring period, the Sponsor must receive approval by the DWR prior to any mowing activities within Zone 1 and Zone 2 of the Jordan Lake buffers to ensure that no buffer violations have occurred. 4.3 Easement Boundaries and Fencing Easement boundaries will be identified in the field to ensure clear distinction between the Parcel and adjacent properties. Boundaries may be identified by fence, marker, bollard, post, tree -blazing, or other means as allowed by site conditions and/or conservation easement. Boundary markers disturbed, damaged, or destroyed will be repaired and/or replaced on an as needed basis. Contact information for the long-term steward will be provided on boundary markers throughout the site. 4.4 Ownership and Long -Term Management The Site will remain in private ownership, protected in its entirety, and managed under the terms detailed in the conservation easement. Unique Places to Save (UP2Save) will serve as the Grantee and long-term manager and will be the party responsible for long-term management. South Fork Mitigation Site HUC 03030002 — BPDP UP2Save is a 501c3 non-profit organization that is committed to land conservation through sustainable planning and management. UP2Save has the ability, both logistically and financially, to monitor and enforce the provisions of the conservation easement and long-term management plan. The organization operates in a sustainable manner to facilitate operations well into the future. UP2Save has been approved to serve as the easement holder and long-term manager on several mitigation banks in North Carolina. 5.0 Financial Assurance Following approval of the South Fork BPDP, the Sponsor shall provide a Performance Bond from a surety that is rated no less than an "A-" as rated by A.M. Best. The Performance Bond amount shall be 100% of the estimated cost for implementation of the project as described in the BPDP, but not less than $150,000.00. In lieu of posting the performance bond, the Sponsor may elect to construct the project prior to the first credit release. In that case no performance bond will be necessary. After completion of the restoration/construction, a separate Performance/Maintenance Bond will be secured for 100% of the estimated cost to implement the monitoring and maintenance plan but not less than $100,000.00. The Performance/Maintenance Bond shall apply at the inception of the monitoring period for a term of one year, to be extended annually for a minimum of five years. Upon DWR approval, this may be lowered each year based on the adjusted cost to complete the monitoring. Performance bonds for monitoring shall be renewed to cover the next years monitoring period, with confirmation of renewal provided to DWR with each annual monitoring report when applicable. DWR reserves the right to alter the credit release schedule if monitoring reports are submitted without proof of bond renewals when applicable. Financial assurances provided in this section must be separate from the financial assurances provided as part of the Stream and Wetland Mitigation Bank. 6.0 Mitigation Potential Approximately 18.13 acres will be protected with a permanent conservation easement. Out of the 18.13 acres, a total of 15.30 acres of riparian areas will be mitigated to generate Jordan Lake riparian buffer credit or nutrient offset credit. Out of those 15.30 acres, 5.48 acres will be restored, 8.84 acres will be enhanced by permanently excluding livestock and stabilizing soils, 0.52 acres will be enhanced through supplemental plantings, and 0.46 acres will be preserved (Figure 5). Of the 5.48 acres that are restored, all 5.48 acres were deemed to be agriculture by DWR and are therefore suitable for either buffer credit or nutrient offset credit by DWR. These areas may be used for either Jordan Lake buffer credits or nutrient offset credits, but not both. Out of the 5.48 acres that are restored, the Sponsor is requesting all 5.48 acres to be used to generate credit releases for riparian buffer credits. Neither riparian buffer nor nutrient offset credit will be generated on the remaining 2.83 acres (Figure 5). Riparian zones are depicted in Figure 6. The Sponsor will maintain up to four (4) credit ledgers. One to account for buffer preservation and enhancement (via cattle exclusion) credits, one to account for buffer restoration and enhancement credits (under Rule 15 NCAC 2B .0295(n)) , one to account for Nitrogen nutrient offset credits, and one to account for Phosphorus nutrient offset credits (if riparian buffer credits are ever converted to nutrient credits). All buffer ledgers will report credits in both square feet and acres and nutrient offsets in both pounds and acres. Nutrient offset ledgers must also show both generated credits and delivered credits. Overall credit generation by drainage feature is detailed in Table 5. The total credit generation is summarized in Tables 6a and 6b and visually represented in Figure 5. The Sponsor must request and receive approval from DWR prior to any credit conversions and transfers to the credit ledgers. With each South Fork Mitigation Site HUC 03030002 — BPDP conversion and transfer request submitted to the DWR, the Sponsor will provide all updated credit ledgers showing all transactions that have occurred up to the date of the request. Buffer preservation and enhancement credits (via cattle exclusion) from this Bank cannot be converted into Nutrient offset credits. The credit release schedule is shown in Table 7. Table 5.
