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 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 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 riparian buffer mitigation through the creation of a Buffer Bank. Riparian restoration, enhancement, and preservation activities deemed suitable for riparian buffer mitigation will generate 250,905.60 ft2 of riparian buffer mitigation credits. For purposes of the Bethel Branch 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 16.30 acres will be protected with a permanent conservation easement. Out of the 16.30 acres, 10.93 acres will be mitigated to generate Jordan Lake riparian buffer credit. Out of the 10.93 acres, 2.95 acres qualify for buffer restoration, 5.07 acres for enhancement (via cattle exclusion), and 2.91 for buffer preservation. In general, riparian areas that are restored, enhanced or preserved for buffer credits, will be a minimum of 30 feet from the top of stream banks and out to a maximum of 100 feet. The mitigation credits issued for riparian buffer preservation will be adjusted per 15A NCAC 0295 (o)(5) and are outline in more detail in Section 6. 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 23, 2017. 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 Bethel Branch Bethel Branch Mitigation Bank Parcel HUC 03030002 — BPDP Bank Parcel (35° 49' 45.56" N and 79° 22' 11.37" 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). From Raleigh, take US -64 West to the exit for NC -87 N. Continue north on NC -87 for 1.8 miles and turn left onto Silk Hope Gum Spring Road. Continue on Silk Hope Gum Spring Road for 8.1 miles. Turn right onto Silk Hope -Lindley Mill Road and continue for 2.9 miles. Turn left onto Moon Lindley Road and continue for 0.6 miles. 2.0 Project Area - Existing Conditions 2.1 Parcel Features The project includes restoring, enhancing, and preserving riparian areas along three unnamed tributaries to South Fork Cane Creek, as shown on Figure 3 and listed in Table 1. Table 1. Project Features Descriptions — Bethel Branch BPDP Feature Name** Feature ID from DWR Assessments DWR Classification Buffer Credit Viable UT1 UT -1 Perennial Yes UT2 UT -2 Perennial Yes UT3 UT -3 Upstream Ephemeral No* UT -3 Downstream Intermittent Yes * Pond on UT3 is being removed and channel restored as part of the stream and wetland mitigation project. UT3 will be re- evaluated after construction to determine viability of the buffer based on the new channel characteristics. Area upstream of the pond is no longer included in the project. 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. UT1, UT2, and UT3 Downstream were determined to be subject to the Jordan Lake Buffer Protection Rule 15A NCAC 02B .0267. UT3 Upstream is not subject to the Jordan Lake Buffer Protection Rules. The pond on UT3 is not currently viable for buffer credit based on the DWR August 15, 2017 evaluation but is being removed and the channel restored as part of the stream and wetland mitigation project. The Sponsor requests that DWR re-evaluate the channel after construction to determine if credits are viable on the newly restored channel. Photos showing historic site conditions and current site conditions (as of July 2018) of the Parcel are provided in the appendix. Site conditions have not changed since the DWR 2017 viability letter and July 2018 site photos. 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 Bethel Branch project area is dominated by Cid-Lignum soils. These soils are well drained. The 2006 Soils Survey Map is provided in Figure 4. kBethel Branch Mitigation Bank Parcel HUC 03030002 — BPDP Table 2: Project Soil Types and Descriptions — Bethel Branch BPDP Soil Name Location Description Cid-Lignum Mapped along the majority of Cid and Lignum soils series are gently sloping, complex, CmB UT1, UT2, and UT3. moderately deep, moderately well -drained soils.

They are very deep (>80") and well drained soils. Source: Chatham County Soil Survey, USDA-NRCS, http://efotg.nres.usda.gov 2.3 Existing Vegetative Communities The livestock pastures on the site are dominated by fescue grasses (Festuca spp.). Much of the riparian area on UT3 is wooded; however, livestock have access to the streams throughout. The majority of UT1 and UT3 have little to no riparian vegetation and livestock have access to these systems. Vegetation in the wooded areas is primarily comprised of deciduous canopy species including willow oak (Quercus phellos), tulip poplar (Liriodendron tulipifera), sweetgum (Liquidambarstyraciflua), and red maple (Acer rubrum). 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. Three 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 Chatham County, NC — Bethel Branch BPDP Species Federal Status Common Name Scientific Name Red -cockaded woodpecker Picoides borealis Endangered Bald Eagle Haliaeetus leucocephalus BGPA 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 Bethel Branch Mitigation Bank Parcel HUC 03030002 — BPDP 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 June 24, 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 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 — Bethel Branch Stream Mitigation Plan (USACE # 2016-00219) and the Bethel Branch 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 Bethel Branch Stream Mitigation Plan for the Cane Creek Umbrella Mitigation Bank. Buffer mitigation credit is not being requested in wetland mitigation areas. 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 Bethel Branch Mitigation Bank Parcel HUC 03030002 — BPDP 4 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 — Bethel Branch 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 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 For buffer enhancement areas under NCAC 02B .0295(0), 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(0). 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 February 2019. Bethel Branch Mitigation Bank Parcel HUC 03030002 — BPDP 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 no more than one -hundred feet. A total of 2 plots will be established within the buffer restoration credit generation area (Figure 7). 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 2 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 February 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 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 parce maintenance performed will be included in the monitoring report for that year. A rigorous herbicide Bethel Branch Mitigation Bank Parcel qiV HUC 03030002 — BPDP 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, 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. 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 Bethel Branch 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. Bethel Branch Mitigation Bank Parcel HUC 03030002 — BPDP 6.0 Mitigation Potential Approximately 16.30 acres will be protected with a permanent conservation easement. Out of the 16.30 acres, a total of 10.93 acres of riparian areas will be mitigated to generate Jordan Lake riparian buffer credit. Out of those 10.93 acres, 2.95 acres will be restored, 5.07 acres will be enhanced by permanently excluding livestock and stabilizing soils, and 2.91 acres will be preserved (Figure 5). The mitigation areas will be a minimum of 30 feet from the top of stream bank (Figure 6). Overall credit generation by drainage feature is detailed in Table 5. The mitigation acreages in Table 5 were calculated prior to applying any reductions in riparian buffer credits for the 2:1 and 10:1 credit ratios applied to enhancement of grazing areas and preservation of rural streams respectively nor were any reductions that are required by 15A NCAC .0295(0)(5) applied to the preservation totals. All ratios and rules are applied to the credit totals depicted in Tables 6a and 6b. Table 5. Mitigation Activities by Drainage Feature - Bethel Branch BPDP *The area of preservation credit within a buffer mitigation site shall comprise of no more than 25% of the total area of buffer mitigation per 15A NCAC 0295 (o)(5) and will therefore be reduced accordingly in Table 6: Credit Generation Summary The Sponsor will maintain two (2) credit ledgers. One to account for buffer preservation and enhancement (via cattle exclusion) credits and one to account for buffer restoration credits. All buffer ledgers will report credits in both square feet and acres. The total credit generation including the existing pond is summarized in Table 6a and visually represented in Figure 5. The area of mitigation proposed adjacent to the existing pond on UT3 will be held until after construction of the stream and wetland restoration project has occurred and DWR has evaluated the viability of the channel post construction. The total credit generation without the former pond area is summarized in Table 6b.
