This Parcel was built to provide riparian buffer mitigation credits for unavoidable impacts due to development within the Neuse River Basin, United States Geological Survey (USGS) 8-digit Hydrologic Unit Code (HUC – 03020201) (Figure 1). This Parcel is in accordance with the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 and the RES Poplar Creek Umbrella Mitigation Banking Instrument (UMBI), made and entered into by EBX-Neuse I, LLC acting as the Bank Sponsor (Sponsor), and the North Carolina Department of Environmental Quality-Division of Water Resources (DWR). The BPDP has also been constructed in concurrence with Uzzle Stream Mitigation Site in the Neu-Con Stream and Wetland Umbrella Mitigation Bank (SAW# 2016-01973). The mitigation plan for the Uzzle Stream Mitigation Bank was approved by Interagency Review Team (IRT) in February 2019. The Uzzle Parcel is located in Johnston County approximately six miles southeast of Clayton, North Carolina. The Parcel is located within Neuse River Basin USGS 14-digit HUC 03020201100040, a Targeted Local Watershed, and DWR Subbasin Number 03-04-02. To access the Parcel head West on NC 70 from the Town of Wilson Mills and turn left onto Meta Drive. The Parcel is accessible from the end of Meta Drive. The coordinates of the site are 35.585186 N, -78.393553 W. The easement is separated by an agricultural crossing, dividing the site into an upper and lower portion. The upper portion of the project includes reaches LP1, LP2, LP3, LP4, and LP5. The lower portion of the project includes reaches LP5, LP6, and LP7. The overall drainage area of the Parcel is approximately 2.05 miles squared. Little Poplar Creek (LP1, LP2, LP4, LP5, and LP7) is a perennial stream channel and the two unnamed tributaries (LP3 and LP6) have been classified as intermittent and confirmed by DWR staff Furthermore, it was confirmed, by DWR staff, that all riparian areas adjacent to streams associated with this proposed bank have active cattle grazing. Stream identifications and buffer viability assessments were performed by the DWR at the January 13, 2017 site visit. For purposes of the Uzzle Riparian Buffer Bank, the Parcel involved enhancing riparian buffers and other riparian areas adjacent to mitigated streams onsite. Of the 27.27 acres protected in the conservation easement, 13.45 acres are enhanced by the removal of cattle from the streams and riparian areas for Neuse riparian buffer credit only. The BPDP generates credit within the 20-30 foot range, 0-50 foot and 151-200 foot buffer from the proposed top of bank. Majority of the project streams have a riparian buffer of at least 50 feet, excluding crossings and a portion of LP5 and LP6 due to the parallel gas-line easement. Credit within the 51-150 foot buffer zone was claimed for additional stream credit in the Uzzle Stream Mitigation Bank. There is no overlap in the buffer bank credit areas and the buffer for stream credit areas. The stream credit area is solely used for the generation of stream mitigation credits and is not used for the generation of any Uzzle Buffer 2 Year 5 Monitoring Report Mitigation Site October 2023 other credit. Also, riparian buffer enhancement credits generated on this Bank Parcel are allowed pursuant to 15A NCAC 02B .0295 (o)(6) but are not used to generate nutrient offset credits. 1.2 Project Success Criteria Annual vegetation monitoring is to occur each year for a minimum of five (5) years and is to be conducted during the fall season with the first year occurring at least 5 months from initial planting. As part of the stream mitigation plan 3.6 acres were planted and four monitoring plots were installed a minimum of 100 m2 in size. These plots cover at least two percent of the planted mitigation area for the Stream Mitigation Bank. All four plots are within the riparian buffer that are measuring success of both the stream mitigation and the buffer riparian area. Data for the plots is to be provided in the Monitoring reports, as a courtesy to the DWR. The following data is to be recorded for all trees in the plots: species, height, planting date (or volunteer), and grid location. All stems in plots are to be flagged with flagging tape. Photos are to be taken from all photo points each monitoring year and provided in the annual reports. Visual inspections and photos are to be taken to ensure that enhancement areas are being maintained and compliant. The measures of vegetative success for the parcel are based on the Uzzle Stream Mitigation Plan (Action ID #SAW-2016-01973). Invasive and noxious species are to be monitored and controlled so that none become dominant or alter the desired community structure of the site. A visual assessment of the cattle exclusion areas within the conservation easement is to be performed each year with all observations provided in the annual monitoring reports, 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 conservation easement area; and • there has not been any cutting, clearing, filling, grading, or similar activities that would negatively affect the functioning of the buffer. RES is to monitor the stream mitigation bank for a minimum of seven years, or until IRT approval. Therefore, all plots will be monitored in accordance with the monitoring protocol in the Uzzle Stream Mitigation Plan. 1.3 Project Components This Bank generates approximately 6.17 acres (268,834.036 ft2) of buffer enhancement credits. The approximately 0.21 acre decrease in creditable area following the as-built was due to the removal of buffer areas less than 20 feet from the top of bank. The riparian buffer mitigation credits generated service Neuse buffer impacts within the USGS 8-digit HUC 03020201 of the Neuse River Basin, excluding the Fall Lake Watershed. The Sponsor is to maintain one credit ledger. The one ledger shall account for buffer enhancement credits. All mitigation credit assets shall be shown Uzzle Buffer 3 Year 5 Monitoring Report Mitigation Site October 2023 on this credit ledger. The total potential mitigation credits that the Uzzle Bank generates are summarized below. Table 1.

Livestock were completely removed from Parcel, in perpetuity by way of conservation easement and installation of fencing. After construction activities, the subsoil was scarified, and any compaction was deep tilled before the topsoil was placed back over the site. Any topsoil that was removed during construction was stockpiled and placed over the site during final soil preparation. This process provides favorable soil conditions for plant growth. Bare root plantings and live stakes were planted according to the planting plan. Enhancement occurred in areas of grazing adjacent to the stream in accordance with the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 (o)(6). Where livestock was present, RES installed cattle exclusion fencing to prohibit access to riparian areas and their associated streams. All fencing was installed to NRCS specifications. Riparian enhancement adjacent to streams was approved by the DWR in their Buffer Viability letter dated January 13, 2017. All enhancement activities began from the tops of the stream banks and extended outward a maximum of 200 feet perpendicular to the stream channel where possible pursuant to 15A NCAC 02B .0295 (effective November 1, 2015). It is important to note that areas along all reaches, between the 50-150-foot buffer width zone, within the project was used to generate additional stream credit for the Uzzle Stream Mitigation Bank. This area is solely being used for the generation of stream mitigation credits and is not be used for the generation of any other credit. Buffer crediting is generated from the 0-50 foot and 151-200-foot buffer width zones, with a small area of credit being generated within the 20-30-foot buffer zone due to project Uzzle Buffer 4 Year 5 Monitoring Report Mitigation Site October 2023 limitation with a gas line easement. Buffer enhancement can only generate buffer mitigation credit and is not transferrable into nutrient offset credits. All riparian enhancement activities commenced in concurrence with the stream mitigation activities and not before. Stream restoration activities based on the design approach included meandering the proposed channel within the natural valley, backfilling the existing stream channel, and reconnecting a new channel to its floodplain. Diffuse flow is to be maintained throughout the mitigated riparian areas. 1.5 Construction and As-Built Conditions Revegetation of the site included treating invasive species and planting native hardwood bare root trees in areas where stream restoration occurred. Prior to planting, RES prepped the site by spraying and ripping that section of the easement. Coastal Plain Small Stream Swamp is the target community type and was used for all areas within the project. The community is defined by Schafale (2012). The planting of bare root trees occurred in May 2019. Deviations from the initial planting plan were due to bare root availability. A list of the planted species can be found in Table 2. Stream construction activities were completed in May 2019. RES submitted a Stream As-Built Report in July 2019 to USACE and conducted a site visit in July 2019 with no comments. The site was constructed in accordance with the Approved Mitigation Plan and associated permits. RES acquired 404 (SAW-2016-01973), 401 (DWR # 2016-0981), and NPDES Erosion and Sediment Control Plan (JC# 19-012-P) Permits. The conservation easement is marked every 150-200 feet with North Carolina Wildlife Habitat Foundation signs attached to either fences or t-posts. A fence was installed around the entire easement as livestock were present throughout. 1.6 Year 5 Monitoring Performance The Uzzle Year 5 Monitoring (MY5) activities were completed in September 2023. All MY5 data is present below and in the appendices. Although the Uzzle Site was buffer enhancement credit for the exclusion of cattle via fencing, RES monitored the riparian buffer that was planted due to stream restoration and reported to DWR over the past five years. At the close of this project, the planted area has met the vegetation success criteria for DWR of the survival of at least four native hardwood tree species, where no one species is greater than 50 percent of the stems, at a density of at least 260 planted trees per acre at the end of Year 5. Additionally, the measured performance criteria that all cattle exclusion is still in place has also been met. Monitoring of the four permanent vegetation plots was completed during September 2023. Vegetation tables and data are in Appendix B and associated photos are in Appendix C. MY5 monitoring data indicates that all plots are exceeding the interim success criteria of 260 planted stems per acre. Planted stem densities ranged from 364 to 647 planted stems per acre with a mean of 536 planted stems per acre across all plots. A total of 11 species were documented within Uzzle Buffer 5 Year 5 Monitoring Report Mitigation Site October 2023 the plots. Volunteer species were noted in three plots, with an average of 61 stems per acre. The average tree height observed was 9.2 feet. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. A boundary site walk was performed in June 2023 and ensured that the fencing was in good condition and there was no evidence of cattle in the easement. There was no encroachment observed or similar activities that would negatively affect the functioning of the buffer. Diffuse flow was also maintained throughout the conservation easement area. Highway 70 expansion is currently occurring along the easement boundaries. RES is monitoring the easement on a regular basis to ensure that no encroachment or issues are impacting our easement as construction is occurring. A few small areas of re- sprouted Chinese privet observed in 2023 and were treated in September 2023. 2.0 Methods Vegetation success is being monitored at four permanent monitoring plots. Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and density of planted species. Data is processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with PVC at the origin and metal conduit at the other corners. Photos of each plot are to be taken from the origin each monitoring year. 3.0 Monitoring Complete The site monitoring is complete, meeting the vegetative success criteria described in Section 1.2. Overall, the Bank is performing as planned, with vegetation well established throughout the Parcel in Year 5 including planted woody stems, volunteer native stems, live stakes, and herbaceous ground cover. All fencing is intact, and the cattle exclusion performance criteria has been met. No other problems were identified during the final Year 5 monitoring. 4.0 Reference Uzzle Buffer 6 Year 5 Monitoring Report Mitigation Site October 2023 Environmental Banc & Exchange – Neuse I, LLC (2018).
