The Mitigation Banking Instrument (MBI) for the Bank and the Bank Parcel Development Plan (BPDP) were approved on July 18, 2018. The project was planned, designed, and constructed encompassing land along tributaries to South Fork Cane Creek in Chatham County, NC (Figure 1). The purpose of the Parcel is to provide riparian buffer and nutrient offset mitigation credits to compensate for buffer impacts and development requiring nutrient offset payments according to the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 (effective November 1, 2015) and development requiring nutrient offset payments according to 15A NCAC 02B .0240 within the Haw River Sub-watershed of the Jordan Lake Watershed. The service area is depicted in Figure 2. 1.0 Introduction This Parcel was developed to provide stream mitigation through the creation of a Stream Bank Site as well as nutrient offset and buffer mitigation through the creation of a Buffer & Nutrient Offset Bank. Riparian restoration activities deemed suitable for nutrient offsets on this Parcel, will generate 2,249.36 lbs. -Nitrogen per acre and 143.81 lbs. -Phosphorus per acre (with a delivery factor of 71% and 67% respectively). The Parcel involved 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 and within the Cape Fear River Basin. Approximately 18.13 acres are protected with a permanent conservation easement. Out of the 18.13 acres, 14.83 acres have been restored for either Jordan Lake riparian buffer credit or nutrient offset credit. In general, riparian buffer restoration area widths on streams range from 50 feet to 100 feet from the top of bank for Jordan Lake buffer credits and nutrient offset credit. 2.0 Parcel Location & Background 2.1 Project history The construction of the Stream Bank site was completed in July 2018. No major adjustments were made during construction that drastically affected the Buffer and Nutrient Offset Bank. Buffer and Nutrient Offset credits were adjusted to reflect the presence of vernal pools that were added during construction, and a minor alignment adjustment to UT2. The As-Built monitoring report was approved in May 2019 by Department of Water Resources (DWR) officials. More details on project history can be found below in Table 1.

Turn left onto Johnny Lindley Road and continue for 0.7 miles to 1727 Johnny Lindley Road, Snow Camp, NC (Figure 1). 2. 3 Parcel Background Prior to construction, the Parcel consisted primarily of livestock pasture except for a few areas that were already forested. The cattle pastures on the site were dominated by fescue grasses (Festuca spp.) and broomsedge (Andropogon virginicus). Much of the riparian areas on the site were wooded; however, cattle had access to the streams. 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 (Liquidambar styraciflua), red maple (Acer rubrum), southern red oak (Quercus falcata), and American elm (Ulmus americana) (Table 2).

The riparian buffer will immobilize nutrients, reducing quantities available to downstream aquatic ecosystems in the Cape Fear River Basin. Table 3.

The specific species composition that was 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 (Table 3). Trees were 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. An appropriate seed mix was also applied to provide ground cover for soil stabilization and reduction of sediment loss, as necessary. While planting was not anticipated to be needed in the cattle exclusion areas, except where required in the stream mitigation plan, a seed mix was applied where cattle had removed all vegetation and caused bare soils. The cattle exclusion areas within the easement were fenced to prevent further cattle encroachment by using Three-Strand High Tensile Wire Fence. No planting was performed in the buffer preservation areas except in areas affected during construction.

The number of plots required was determined in accordance with the Carolina Vegetative Sampling Protocol (CVS) Levels 1 & 2. Vegetation assessment was conducted in January 2019 following the CVS Levels 1 & 2 Protocol for Recording Vegetation, Version 4.0 (Lee et al. 2006). Performance Standards for the Project are based on the health and survival of a minimum density of 260 trees per acre after five years of monitoring, and no one species comprises more than 50 percent of stems. Height, visual assessment of damage, and vigor are used as indicators of overall health. Desirable volunteer species may be included to meet the success criteria upon NCDWR approval. A reference photo was taken from the southwestern corner of each vegetation plot and included in the appendix. All planted stems in the vegetation plots were marked with flagging tape and recorded. The total number of each tree species planted within the monitoring plots, as well as planting density, and composition at as-built are included in Table 4 for comparison purposes. Annual monitoring activities began in the fall of 2019, resumed in September 2020, and will continue each year for the remainder of the monitoring period. Species composition, density, and survival rates will be evaluated on an annual basis by plot for the entire site. An annual monitoring report will be submitted to NCDWR no later than December 31st of each year for five consecutive years. 3.2 Results of Vegetation and Visual Assessment Monitoring The 5 vegetation plots (Plots 3-7) were sampled in September 2020 at the end of the second growing season. A reference photo was taken from the southwest corner of each plot, which can be found in Appendix D along with the stem count raw data. Total numbers of tree species identified within the monitoring plots as well as density and composition are summarized in Table 5. Vegetation result tables with planted stem density, and stem count by plot and species are summarized in Appendix C. The 2020 vegetation monitoring resulted in an average planted stem density of 510 stems per acre (Table 5) and a living stem density of 826 (with the inclusion of volunteer species), which is greater than South Fork Nutrient Offset and Buffer Mitigation Bank Parcel Page 6 Monitoring Year 2 – October 2020 the final requirement of 260 stems per acre and has not changed drastically since the as-built density of 607 stems per acre recorded in January 2019. Volunteer species will be monitored to make sure they do not out compete planted species. If volunteer species hinder the growth of planted trees remedial actions will be taken, as necessary. Visual assessments of the cattle exclusion and preservation areas within the conservation easement concluded: • 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. The Site is on track to meet its final success criteria. Table 5.

Fencing locations were agreed upon with the landowner and are displayed accurately in Figures 3 and 4. 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. Site maintenance will be performed to correct any identified problems 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. 5.0 Conclusions The 2020 vegetation monitoring data reflects that the Parcel has not suffered significant mortality and is on trajectory to achieve final vegetative success criteria of 260 stems per acre by the end of Monitoring South Fork Nutrient Offset and Buffer Mitigation Bank Parcel Page 7 Monitoring Year 2 – October 2020 Year Five. No problems were identified, such as invasive species or excessive tree mortality, during Monitoring Year Two. Therefore, no corrective actions are required at this time. 6.0 References Guidelines for Riparian Buffer Restoration.
