The Bank Parcel was made under the terms and conditions of the accepted EMH Farm Mitigation Banking Instrument (MBI). The Bank Parcel was designed to provide riparian buffer mitigation credits (RBC) for unavoidable impacts due to development within the Randleman watershed of the Cape Fear River Basin per the Randleman Nutrient Strategy (15A NCAC 02B .0724). The Bank Parcel was planned and designed according to the MBI with NCDWR, and the Consolidated Mitigation Rule 15A NCAC 0213.0295, which became effective on November 1, 2015. Stormwater runoff from the Bank Parcel drains directly to unnamed tributaries to the Deep River, just upstream from the Randleman Reservoir. According to the final Cape Fear River Basin Restoration Priorities (NCEEP 2009), this watershed should be targeted for restoration to protect the critical area that ultimately drains into the WS-IV water supply at Randleman Reservoir. Mitigation activities will reduce sediment and nutrient levels and improve water quality within the Bank Parcel and their downstream watersheds. The Bank Parcel includes the restoration, enhancement, and preservation of riparian areas along three unnamed tributaries and two ephemeral channels in Guilford County, NC. The sole purpose of the Bank Parcel is to provide RBC to mitigate buffer impacts within the Randleman Lake Watershed, Hydrologic Unit Code (HUC) 03030003 and the NCDWR Sub -basin 03-06-08 of the Cape Fear River Basin. All riparian areas were assessed by NCDWR during an onsite visit to determine viability for buffer mitigation. Approximately 26.81 acres are protected with a permanent conservation easement. Of those 26.81 acres, 21.35 acres are being restored, 1.10 acres are being enhanced by supplementally planting partially forested riparian areas, and 3.11 acres are preserved. Riparian restoration/enhancement area widths on streams and ephemeral channels extend out to a maximum of 200 feet from the top of bank with a minimum width of 20 from top of banks. Riparian buffer enhancement and preservation credits generated on this Bank Parcel are allowed pursuant to 15A NCAC 02B .0295 (n), 15A NCAC 02B .0295 (o)(5), and 15A NCAC 028 .0295 (o)(7). No nutrient offset credit will be generated on the Bank Parcel. 2.0 BANK PARCEL LOCATION Located in the South Atlantic/Gulf Region approximately 4 miles east of Archdale, NC in southwest Guilford County (Figure 1, Appendix A), the Bank Parcel is hydrologically situated within the USGS 14-digit HUC 03030003010050 of the Cape Fear River Basin and Randleman Lake Watershed (North Carolina Division of Water Quality Subbasin Number 03-06-08). Directions to the Site from Raleigh, North Carolina. ➢ Head west on 1-40 for 69 miles ➢ Just after Exit 220, stay left, following signs for 1-85 Bus S ➢ Continue onto 1-85BL S/US-29 S/US-70 W, and travel 2.8 miles ➢ Take Exit 33 toward 1-73 N/Groometown Road As -Built & Baseline Monitoring Report page 5 EMH Farm Buffer Mitigation Bank Parcel Clearwater Mitigation Solutions Guilford County, North Carolina August 2023 ➢ Keep left at the fork, following signs for Groometown Road ➢ Turn left onto Groometown Road ➢ The Site on the right after 5.7 miles o Site Latitude, Longitude 35.91949N, 79.89419W (WGS84) 2.1 Bank Parcel Background The Bank Parcel encompasses 26.81 acres of land containing unnamed tributaries to the Deep River. It is located in a region of the state dominated by agriculture and livestock, but is also affected by urban runoff from nearby Archdale and High Point. Restoration of the riparian buffer is expected to result in immediate water quality benefits within the vicinity of the Bank Parcel through the removal of livestock access to streams and ephemeral channels, as well as the establishment of riparian vegetation. Situated within the Southern Outer Piedmont portion of the Piedmont Ecoregion of North Carolina, the Bank Parcel's regional physiography is characterized by dissected irregular plains; low rounded hills and ridges; and low to moderate gradient streams with mostly cobble, gravel, and sandy substrates. On -site elevations range from a high of 802-feet NGVD above the upper reaches of UT 2 to a low of approximately 750-feet NGVD at the Bank Parcel outfall (USGS High Point East, North Carolina 7.5-minute topographic quadrangle). Surrounding land use consists primarily of wooded and agricultural land, with some low -density residential housing. Three unnamed tributaries (UTs) were deemed subject to the Randleman Lake Buffer Protection Rule (15A NCAC 02B .0724) by NCDWR in correspondence dated September 24, 2021 (NCDWR Site Viability Letter, Appendix B). The upper portion of UT2 (Feature E-1) and Feature E-2 are ephemeral streams and were determined to be not subject. The drainage areas of site streams range from 0.007 miz to 0.24 miz. Present and historical land use practices included the maintenance and removal of riparian vegetation and the relocation, dredging and straightening of onsite streams. This resulted in degraded water quality and unstable channel characteristics (stream entrenchment, erosion, bank collapse, and stream aggradation). 2.2 Project Goals and Objectives The major goals of the riparian buffer mitigation project are to provide ecological and water quality enhancements to the Randleman watershed by restoring the riparian area to create a functional riparian corridor. Specific enhancements to water quality and ecological processes are outlined in Table 1. As -Built & Baseline Monitoring Report page 6 EMH Farm Buffer Mitigation Bank Parcel Clearwater Mitigation Solutions Guilford County, North Carolina August 2023 Table 1. Ecological and Water Qualitv Goals Goal Objective Nutrient input will be decreased by filtering runoff from the agricultural Decrease nutrient levels fields through restored native buffer zones. The off -site nutrient input will also be absorbed on -site by filtering flood flows through restored floodplain areas, where flood flows can disperse through native vegetation. Decrease Sediment Input Sediment from off -site sources will be captured by deposition on restored floodplain areas where native vegetation will slow overland flow velocities. Decrease water temperature and Planted riparian trees will shade the streams as they mature reducing increase dissolved oxygen concentration thermal pollution. Create appropriate riparian habitat Riparian areas adjacent to streams and ephemeral channels will be restored by planting native vegetation. Permanently protect the parcel from A conservation easement will be recorded on the Bank Parcel. harmful uses 3.0 RESTORATION ACTIVITIES 3.1 Riparian Area Restoration Activities Riparian area restoration involved an herbaceous treatment of existing fescue grasses, shallow ripping of pasture areas, paralleling streams and ephemeral channels to promote floodwater attenuation by increasing frictional resistance of floodwaters crossing Bank Parcel floodplains, and planting appropriate native tree species along the riparian corridor throughout Bank Parcel riparian restoration areas (21.35 acres). Continued herbicide applications may be needed over the first few years of tree establishment in the riparian restoration areas to prevent encroachment of undesirable species, such as fescue and Tree of Heaven, that may out -compete the planted native vegetation. Tree species planted across the Bank Parcel are listed in Table 2. Table 2.

Bare -root tree stock was mixed during planting to ensure diversity and that no one tree species will be greater than 50% of the established stems As -Built & Baseline Monitoring Report EMH Farm Buffer Mitigation Bank Parcel Guilford County, North Carolina page 7 Clearwater Mitigation Solutions August 2023 in permanent vegetations plots. Planting occurred on April 20, 2023. As -built measurements indicate that all nineteen plots are meeting success criteria, with an average of 555.9 stems per acre (Table 5, Appendix Q. Several additional restoration activities occurred on the Bank Parcel. Three total culverts were removed: a non-functioning culvert on UT 1, and two functioning culverts on UT 2 and UT 3. The culverts were removed with a mini -excavator with low pressure tracks, and impacted stream banks were sloped at 3:1 grade, matted, seeded, and live -staked to ensure future stability. An existing ditch feature along the eastern boundary of the Bank Parcel (Feature E 3) was plugged and filled for diffuse flow into UT 3. Graded/disturbed areas were strawed and seeded to minimize sediment inputs. Minor bank stabilization was needed along UT3. This included mechanically sloping at 3:1 grade, matting, seeding, and live -staking. Appropriate seed mixes of pollinator -attracting annual and perennial species were applied to provide temporary and permanent ground cover for soil stabilization and reduction of sediment loss during rain events in areas without existing herbaceous cover, especially where earthwork was performed. Seed mixes are listed in Tables 3A-B. The pasture area surrounding the Bank Parcel will be abandoned by the landowner, and existing fencing will be maintained to permanently exclude cattle from the conservation easement area. Additionally, a small section of fencing within the easement boundary was removed. Table 3A.

Enhancement areas (1.10 acres) on the Bank Parcel were primarily disturbed mixed hardwoods and were supplementary planted (Figure 2). The enhancement area extends a maximum of 200 feet from the top of bank with a minimum width of 20 feet from the top of bank. As -Built & Baseline Monitoring Report page 8 EMH Farm Buffer Mitigation Bank Parcel Clearwater Mitigation Solutions Guilford County, North Carolina August 2023 3.3 Riparian Buffer Preservation Activities Riparian buffer preservation includes permanently protecting existing riparian buffer from cutting, clearing, filling, grading, and any similar activities that would affect the functionality of the riparian buffer. Areas specified for Preservation, as defined in 15A NCAC 02B .0295, are shown in Figure 2 (Appendix A). These areas are primarily mixed hardwoods (3.11 acres), with the number of high value species above 200 stems per acre. They are areas where livestock are currently fenced out, and there has been little or no historic livestock access. 3.4 Bank Parcel Protection A Permanent Conservation Easement will preserve all areas and prohibit all use of the property inconsistent with its use as mitigation property, including any activity that would materially alter the biological integrity of the Bank Parcel. The Sponsor has agreed to transfer or assign the conservation easement and its interests in perpetuity to a qualified holder under NC General Statute ("GS") 121-34 et seq. and 170(h) of the Internal Revenue Code prior to the submittal of the Year 4 Monitoring Report. The holder shall be a land trust or stewardship program that will hold and enforce the conservation easement and the interests in perpetuity. The Sponsor shall choose a land trust or stewardship program that is accredited by the Land Trust Accreditation Commission and/or has been approved by DWR prior to the end of the fourth year of monitoring period. A land trust must be certified under 501(c)(3) of the Internal Revenue Code. The Bank Parcel is surrounded by cattle exclusion fencing. Easement boundaries have been identified in the field to ensure clear distinction between the Bank Parcel and adjacent properties. Boundaries are variously identified by cattle fence, markers on t-post, tree -blazing, or other means as allowed by site conditions. Boundary markers contain contact information for the Bank Parcel. Boundary markers disturbed, damaged, or destroyed will be repaired or replaced as needed. 4.0 MITIGATION POTENTIAL The EMH Farm Mitigation Bank Parcel will provide Randleman Lake RBC for development impacts within the Randleman Lake Watershed (Figure 1 and Table 4). The width of the credit -generating areas will begin at the most landward limit of the top of bank or the rooted herbaceous vegetation and extend perpendicular and landward a maximum distance of 200 feet where the Sponsor is able. No credit -generating areas will be less than 20 feet in width from TOB. Consolidated Mitigation Rule 15A NCAC 0213.0295 (o)(7) states that the area of the mitigation site on ephemeral channels shall comprise no more than 25 percent of the total area of buffer mitigation. Riparian buffer credit generated on ephemeral channels is 9.6 percent of the Bank Parcel's total area of buffer mitigation. Additionally, Consolidated Mitigation Rule 15A NCAC 0213.0295 (o)(5) states that the area of preservation credit within a buffer mitigation site shall comprise of no more than 25 percent of the total area of buffer mitigation. The area of preservation credit comprises 10.4 percent of the Bank Parcel's total area of buffer mitigation. As -Built & Baseline Monitoring Report page 9 EMH Farm Buffer Mitigation Bank Parcel Clearwater Mitigation Solutions Guilford County, North Carolina August 2023 The Sponsor will maintain a credit ledger for the Bank Parcel under the MBI for riparian buffer credits, both in square feet and acres. Credit shall be released in accordance with the schedule described in the MBI. 5.0 MONITORING PROTOCOL AND SUCCESS CRITERIA 5.1 Monitoring Protocol Permanent vegetation monitoring plots were installed and evaluated within the riparian buffer restoration and enhancement areas to measure the survival of the planted trees. The plots are 100 square meters each, randomly placed throughout the planted riparian areas. A total of nineteen (19) plots (2.09% of the restoration/enhancement credit generating area) were established within the riparian restoration and enhancement areas (Figure 2, Appendix A). Planting occurred on April 20, 2023. As -built vegetation monitoring was performed on April 25, 2023. Vegetation assessments are conducted following the Carolina Vegetation Survey (CVS) Level 2 Protocol for Recording Vegetation (Lee et al., 2008). In this baseline monitoring report and each annual report submitted thereafter, a photo taken at the origin of the vegetation plot will be provided (Appendix C). All planted stems are marked with flagging tape and recorded. As - built measurements indicate that all nineteen plots are meeting success criteria, with an average of 555.9 stems per acre (Table 5, Appendix C). The first annual monitoring activities will commence at the end of the first growing season, at least five months after planting was completed and no earlier than the fall season. Species composition, height, survival rates, and vigor will be evaluated on an annual basis for each plot. The total number of volunteer woody stems will also be documented and reported. During a June 5, 2023 as -built site walk-through with NCDWR, three areas with visibly low stem density were delineated (Figure 2, Appendix A; NCDWR Correspondence, Appendix D). One area along the northwestern easement boundary was determined to have been missed during Site planting efforts and will require a supplemental planting effort. The other two areas, one along the easement boundary just north of feature E 2 and another along the right bank of UT 1, were characterized by dense herbaceous vegetation, making it difficult to assess stem density. NCDWR provided the option to perform vegetation transects in these areas during MY1 monitoring to assess whether supplemental planting will be required; however, since a supplemental planting effort will already be required onsite, Clearwater has elected to replant all three areas prior to MY1 monitoring. The supplemental planting effort is detailed in the adaptive management plan (Appendix D) and is scheduled to be implemented during Fall/Winter 2023. Vegetation transects will be performed in planted areas during MY1 monitoring to document sufficient planting. 5.2 Success Criteria The measure of vegetative success for the Parcel will be the survival of at least four native hardwood tree species, where no one species is greater than 50% of the established planted stems, and an established density of at least 260 planted trees per acre at the end of monitoring As -Built & Baseline Monitoring Report page 10 EMH Farm Buffer Mitigation Bank Parcel Clearwater Mitigation Solutions Guilford County, North Carolina August 2023 year five. Appropriate and desirable native volunteer species maybe included in the Bank Parcel's density to meet the performance standards with NCDWR approval. The Sponsor shall submit the annual monitoring report to NCDWR by December 31 of each year for five consecutive years and will follow the terms and conditions of the MBI. 5.3 Bank Parcel Maintenance In the event that the Bank Parcel or a specific component of the Bank Parcel fails to achieve success criteria as outlined in section 5.2, a remedial action plan will be developed and implemented with the approval of NCDWR. Vegetation maintenance and repair activities may include pruning, mulching, and fertilizing. If exotic invasive plant species require treatment, such species will be controlled by mechanical (physical removal with the use of a chainsaw) and/or chemical methods (aquatic approved herbicide) in accordance with North Carolina Department of Agriculture (NCDA) rules and regulations. The easement boundary will be checked annually as part of monitoring activities. Easement boundary conditions and any maintenance performed will be reported in the annual monitoring reports to NCDWR. If mowing is deemed necessary by the Sponsor during the monitoring period, the Sponsor must receive approval from NCDWR prior to conducting any mowing activities within Randleman Buffer Zones 1 and 2 to ensure that no buffer violations have occurred. 6.0 MITIGATION CREDITS, CREDIT RELEASE, & SERVICE AREA 6.1 Credit Generation Approximately 26.81 acres are protected with a permanent conservation easement. Of those 26.81 acres, 21.35 acres are being restored, 1.10 acres are being enhanced by supplementally planting partially forested riparian areas, and 3.11 acres are preserved. Riparian restoration/enhancement area widths on streams and ephemeral channels extend out to a maximum of 200 feet from the top of bank with a minimum width of 20 from top of banks. Riparian buffer enhancement and preservation credits generated on this Bank Parcel are allowed pursuant to 15A NCAC 02B .0295 (n), 15A NCAC 02B .0295 (o)(5), and 15A NCAC 02B .0295 (o)(7). No nutrient offset credit will be generated on the Bank Parcel. Credit calculations are shown in Table 4. 6.2 Credit Release Upon submittal of the appropriate documentation by the Sponsor, and subsequent approval by NCDWR, the mitigation credits associated with the Bank Parcel will be released as described in the MBI. 6.3 Service Area The Bank Parcel Service Area will be the Randleman Lake watershed (Figure 1, Appendix A).

I edited one of the notes in the attached Map to state that if the transects revealed it necessary, that supplemental planting would be provided in the low density areas. Please see attached. It was also discussed onsite, that Kevin would submit an Adaptive Management Plan with the As - Built Report, documenting the As -Built Walk notes and necessary remedial work/supplemental planting necessary. The AMP would need to acknowledge the expectation to perform transects and include that data in the Year 1 Monitoring Report along with the monitoring plot data. The AMP should be attached to the As -Built Report as either an Appendix to the report or included within the text for review and approval by DWR. A timeline and planting plan needs to also be included. Kevin also mentioned that any supplemental planting deemed necessary, would all be done in the Fall/Winter 2023 and documentation confirming that planting effort will be included in the Year 1 Monitoring Report, including the data taken from the transects.
