Salisbury Street, Raleigh, NC 27620 RE: Cox Pond - AsBuilt Report Review Cox Pond Mitigation Bank Parcel (DWR # 2020-1942v2) Wayne County, NC Dear Mr. Hartshorn: Wildlands Engineering, Inc. (Wildlands) has reviewed the Division of Water Resources (DWR) comments dated October 23rd, 2023 regarding the Cox Pond Mitigation Bank Parcel As-Built Report. The following letter documents DWR feedback and Wildlands’ corresponding responses. The DWR comments are listed below in bold, while Wildlands’ responses are noted in italics lettering. 1. In Section 3 please add when DWR completed the as built walkthrough and the results of the walkthrough. The following text has been added to Section 3: On February 27th 2023, NCDWR performed an As-Built Evaluation of the Parcel. The Parcel was approved with no stipulations or further documentation required for the Task 2 credit release as described in the Wildlands Neuse Umbrella Mitigation Banking Instrument (UMBI). 2. On the survey map in Appendix A I am seeing the no credit black shaded areas for the non- diffuse flow which according to the project credit table adds up to 3,079sqft which looks correct but I am not seeing other areas for the missing 2,943sqft. Please confirm the correct non credit area total is 6,022sqft and point out the areas besides the diffuse flow off of Ditch C and B in either figure 3 or 4 in Appendix A. If it is there it is hard to see and we want to account for all areas represented on the survey. The no credit area total is 6,022 square feet. Outside of the diffuse flow deductions, the additional no credit areas are derived from areas within the easement that are greater than 200 feet from the top of bank of project features and a portion where the easement boundary is less than 50 feet from the top of bank of Ditch C. There are multiple no credit areas that are in the >200 foot zone. An inset has been added to Figure 3 showing an example no credit area in the >200 foot zone, however, it is not feasible to include a zoomed in inset depicting each of these areas on a figure. Additionally, an inset has been added that more closely depicts the no credit area along Ditch C.

Wildlands Holdings III, LLC’s Wildlands Neuse Umbrella Nutrient Offset and Buffer Mitigation Bank    The Cox Pond Mitigation Bank Parcel (Parcel) is part of the Wildlands Neuse Umbrella Nutrient Offset  and Buffer Mitigation Bank (Bank). The Bank Parcel Development Package (BPDP) was approved in June  2022. The project features flow to Brooks Swamp off site, which then connects with Thoroughfare  Swamp and subsequently flows to Falling Creek. Falling Creek flows into the Neuse River. The primary  purpose of the project is to provide riparian buffer mitigation credits and nutrient offset credits to  compensate for unavoidable impacts in the Neuse River Basin 03020201 Hydrologic Unit Code (HUC)  outside the Falls Lake Watershed. The project has been planned, designed, and constructed according to  the BPDP, the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 (effective November 1, 2015),  and Nutrient Offset Credit Trading 15A NCAC 02B .0703. The Bank service area is depicted in Figure 2.  1.0 Introduction  The Parcel was restored to provide ecological and water quality enhancements to the Neuse River Basin  by creating a functional riparian corridor and restoring the riparian buffer along four unnamed  tributaries (UT1, UT2, UT3, and UT4), and three project ditches (Ditches A, B, and C). Prior to planting,  the Parcel had been maintained and cleared for row crop cultivation, except for the pond that was filled  prior to the BPDP near the confluence of UT1 and UT3 and a small, forested area along UT1.  Approximately 23.45 acres have been protected along the project features by permanent conservation  easement. The conservation easement was recorded on the Parcel in June 2022.  2.0 Parcel Location & Background  2.1 Location and Setting  The Parcel is in Wayne County, approximately two and a half miles northwest of the Town of Mount  Olive (Figure 1). To reach the Parcel from the City of Raleigh, travel on I‐40 East for approximately 10  miles, following signs for Benson/Wilmington. Take exit 309 for US‐70 E toward Smithfield/Goldsboro.  Continue on US‐70 E for approximately 39 miles then take the exit for I‐795 South, continue on US‐70  BUS E/US‐117 S for 11.5 miles. Take the exit for Country Club Road and turn right. Drive 1.6 miles and  turn right onto Cox Pond Road. Drive 0.8 miles. The parcel is accessible via a dirt access road on the right  (35.2376274, ‐78.0826601). The project is located within the Neuse River Basin 14‐digit HUC  03020201170050 and North Carolina Division of Water Resources (NCDWR) Subbasin 03‐04‐12. The  Parcel was restored for riparian buffer mitigation credit and nutrient offset credit in the Neuse River  Basin HUC 03020201 outside of the Falls Lake Watershed (Figure 2).  2. 2 Parcel Background  Prior to construction, the Parcel consisted mainly of open row crop fields, typically planted with corn,  tobacco, and soybeans. In addition to row crops, there was a small pond that was filled prior to the  BPDP near the confluence of UT1 and UT3 and a small, forested area along UT1. In general, this area has  maintained its rural farming character over the last 70 years with only minor changes in land cover.  Tables 2, 3, and 4 in Appendix A provide detailed information regarding the Project Activity and  Reporting History, Project Contacts, and Project Information and Attributes.   _____________________________________________________________________________________           Cox Pond Mitigation Bank Parcel                                                                                                                Page 2          As‐Built & Baseline Monitoring Report – May 2023  2. 3 Parcel Objectives  The main objective of the Parcel is to reduce nutrient and sediment loading to the Neuse River receiving  waters, supply and improve terrestrial and instream habitats, and improve stream and bank stability. By  restoring native vegetation up to 200 feet from top of bank of the project features, the riparian corridor  will slow overland flow velocities and provide filtration for flood flows. This will result in sediment  deposition and nutrient absorption in the floodplain, and subsequently their reduction in input to  project features.  3.0 Restoration Activities  Developing the Parcel for mitigation required converting existing agriculture land use practices adjacent  to streams into riparian forest. Soils in the project area were disked and much of the easement was  planted with wheat and oats by the landowner as temporary cover and soil stabilization for the winter  before tree planting. Three erosion areas along UT1 were stabilized by live staking banks and in one case  grading the bank by hand to reduce the slope before live stakes were planted. The sides of a large  erosional hole on the southeast bank of UT2 were graded by hand, straw bales were installed around  the edge to diffuse overland flow, and live stakes were planted in the graded slope. Erosional areas on  the banks of Ditch C and UT3 were stabilized by either installing straw bales to divert overland flow or  live staking banks that were bare of vegetation. A temporary seed mix and pollinator blend was spread  around all areas of bank stabilization. Refer to Figure 4 in Appendix A for stabilization locations and  Appendix E for Erosion Stabilization Photographs.  Riparian area restoration involved planting appropriate native tree species along the riparian corridor.  To ensure adequate herbaceous vegetation coverage, a cool season seed mix was spread over the entire  Parcel in January 2023 and in April 2023 a summer seed mix and pollinator blend was spread in areas  with slower vegetation establishment. Additionally, soil test results indicated a need for lime along the  south side of Ditch C and UT3; therefore, 400 pounds were spread in that area along with the summer  seed mix in April. Vegetation management and herbicide applications may be needed over the first few  years of tree establishment in the riparian restoration areas to prevent encroachment of undesirable  species that may out‐compete the planted native vegetation.   The species composition planted was selected based on the desired community type, occurrence of  species in riparian areas adjacent to the Parcel (Appendix A, Table 5), and best professional judgement.  Trees were spaced at 7 feet by 12 feet, which is sufficient to meet the performance standards outlined  in the Rule 15A NCAC 02B .0295. Table 6 in Appendix A lists the tree species and quantities planted on  the Parcel.   The easement was marked using conservation easement placards mounted on t‐posts at approximately  100‐foot intervals following the entirety of the boundary. These signs will be maintained and replaced, if  necessary, throughout the monitoring years.  On February 27th 2023, NCDWR performed an As‐Built Evaluation of the Parcel. The Parcel was approved  with no stipulations or further documentation required for the Task 2 credit release as described in the  Wildlands Neuse Umbrella Mitigation Banking Instrument (UMBI).   4.0 Project Credit Potential and Deviations from the Bank Parcel Development Package (BPDP)  Of the 23.45 acres protected under the conservation easement, 21.57 acres were restored, of which the  sponsor is requesting 9.61 acres be used to generate riparian buffer restoration credit (418,562.000  credits). The remaining 11.96 acres of restored land will be used to generate nutrient offset nitrogen  credits (27,181.936 credits). Buffer preservation credits are also proposed on 0.27 acres within the  _____________________________________________________________________________________           Cox Pond Mitigation Bank Parcel                                                                                                                Page 3          As‐Built & Baseline Monitoring Report – November 2023    conservation easement (1,065.374 credits). In general, riparian restoration area widths on streams  extend out to 100 feet from top of bank along UT1‐3 and the west side of UT4 for riparian buffer credits.  Riparian restoration along the east side of UT4 extends out to 30 feet for riparian buffer credits and  cannot be converted to nutrient offset credits. Riparian restoration width extends from top of bank out  to 200 feet on ditches, with a minimum of 50 feet, and 101 feet to 200 feet on streams for nutrient  offset credits. No major changes to credits were made from the approved BPDP. Small changes in credit  area based on the as‐built survey resulted in an addition of 6.929 nutrient offset credits and a reduction  of 31.729 riparian buffer credits from the credit calculations proposed in the BPDP (31.000 buffer  restoration and 0.729 buffer preservation credits). Table 1 and Figures 3 and 6 in Appendix A detail  credit generation for the Parcel.   5.0 Monitoring Protocol & Success Criteria  Eighteen 10‐meter by 10‐meter vegetation monitoring plots were installed within the riparian  restoration area to measure the survival of the planted trees (Figure 4). The number of plots required  was determined in accordance with the Carolina Vegetative Sampling Protocol (CVS) Level 2. Vegetation  assessments were completed in January 2023 following the CVS Levels 2 Protocol for Recording  Vegetation, Version 4.2 (Lee et al. 2008). Baseline data shows a mean planted stem density of 630 stems  per acre across vegetation plots (Appendix B, Table 7). This surpasses the requirement of 260 stems per  acre at the end of year five monitoring. Each year a reference photo will be taken from the  southwestern corner of each vegetation plot, and all planted stems will be marked with flagging tape  and recorded. Refer to Appendix B for Vegetation Plot Photographs.   Yearly monitoring activities will begin in the fall of 2023 and will commence annually in September or  October for the remainder of the monitoring period. Species composition, density, height, vigor, and  survival rates will be evaluated on an annual basis by plot for the entire Parcel. Wildlands shall submit to  NCDWR an annual monitoring report, no later than December 31st of each year for five consecutive  years and will follow the terms and conditions of the BPDP approved in June 2022. 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 year five. Appropriate and desirable native  volunteer species may be included in the Parcel’s density to meet the performance standards with  NCDWR approval.  6.0 Financial Assurance & Long‐Term Management  6.1  Financial Assurance  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 NCDWR  approval, this may be lowered each year based on the adjusted cost to complete the monitoring.   6.2 Parcel Maintenance  Adaptive measures will be developed, or appropriate remedial actions will be implemented if the Parcel  or a specific component of the Parcel fails to achieve the success criteria. Parcel 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, fire, flooding, drought, or insects that cause excess tree  mortality. Any actions implemented will be designed to achieve the success criteria and will include a  _____________________________________________________________________________________           Cox Pond Mitigation Bank Parcel                                                                                                                Page 4          As‐Built & Baseline Monitoring Report – November 2023    work schedule and updated monitoring criteria. Any Parcel maintenance performed will be included in  the monitoring report for that year. A rigorous herbicide schedule may be implemented in the first few  years of tree establishment in the restoration areas to prevent establishment of invasive species that  may 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. Easement boundary  conditions as well as 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 Zone 1 and Zone 2 of  the Neuse buffers to ensure that no buffer violations have occurred.   7.0 References  Lee, M.T., Peet, R.K., Steven D., & Wentworth, T.R. (2008). CVS‐EEP Protocol for Recording Vegetation

Olive (near 35.234024, -78.079889) Neuse 03020201 Wayne County Dear Ms. Eckardt, On March 22, 2021, Katie Merritt, with the Division of Water Resources (DWR), received a request from you on behalf of Wildlands Engineering, Inc (Wildlands) for a site visit near the above- referenced site in the Neuse River Basin within the 8-digit Hydrologic Unit Code 03020201. The site visit was to determine the potential for riparian buffer mitigation and nutrient offset within a proposed conservation easement boundary, which is more accurately depicted in the attached map labeled “Figure 1-Site Map” (Figure 1) prepared by Wildlands. The proposed easement boundary in Figure 1, includes all riparian areas intended to be proposed as part of the mitigation site. On April 15, 2021, Ms. Merritt performed a site assessment of the subject site. Staff with Wildlands were also present. The site visit revealed the following site constraints: • UTILITIES: A utility easement was observed crossing the site. The utility easement shall not be within a conservation easement or within riparian areas where buffer mitigation or nutrient offset credits are proposed to be generated. • PERMITS: An Animal Feeding Operation (AFO) permit is associated with this property. The permit associated with this property is # AWS960144 and allows for some or all the property to be used for the land application of animal waste per an approved Waste Utilization Plan issued by the DWR. o Application of animal waste will not be permitted within a conservation easement or within riparian areas where buffer mitigation or nutrient offset credits are proposed to be generated. o All riparian areas proposed to be placed in a conservation easement must be removed from the Waste Utilization Plan. o Written approval by DWR of any modification to the existing Waste Utilization Plan and/or the applicable permit will be required prior to approval of the riparian areas to generate buffer mitigation or nutrient offset credits. • EXISTING INFRASTRUCTURE: Existing underground and above ground infrastructure may be present and is likely for purposes of irrigating the property for the land application of animal waste associated with permit # AWS960144.

May 19, 2021 Page 2 of 4 o No infrastructure or impervious areas below or above the ground will be allowed to be within a conservation easement or within riparian areas where buffer mitigation or nutrient offset credits are proposed to be generated. o All infrastructure shall be mapped, including wells and hydrants. Written proof of the removal of all infrastructure within riparian areas proposed to be placed in a conservation easement will be required prior to approval of the riparian areas to generate buffer mitigation or nutrient offset credits. o Changes to any infrastructure associated with permit # AWS960144 will require prior approval from DWR if they result in a change in the irrigation system design for land application. Ms. Merritt’s evaluation of the features onsite and their associated mitigation determination for the riparian areas are provided in the table below. This evaluation was made from Top of Bank (TOB) and landward 200’ from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295 (effective November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0703.

May 19, 2021 Page 4 of 4 proposed easement boundary as well as site constraints identified in this letter could affect the Site’s potential to generate buffer mitigation and nutrient offset credits. This letter does not constitute an approval of this Site to generate buffer and nutrient offset credits. Pursuant to 15A NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to DWR for written approval prior to conducting any mitigation activities in riparian areas and/or surface waters for buffer mitigation credit. Pursuant to 15A NCAC 02B .0703, a proposal regarding a proposed nutrient load-reducing measure for nutrient offset credit shall be submitted to DWR for approval prior to any mitigation activities in riparian areas and/or surface waters. All vegetative plantings, performance criteria and other mitigation requirements for riparian restoration, enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to be eligible for buffer and/or nutrient offset mitigation credits. For any areas depicted as not being viable for nutrient offset credit above, one could propose a different measure, along with supporting calculations and sufficient detail to support estimates of load reduction, for review by the DWR to determine viability for nutrient offset in accordance with 15A NCAC 02B .0703. This viability assessment will expire on May 19, 2023 or upon approval of a mitigation plan by the DWR, whichever comes first. This letter should be provided in any nutrient offset, buffer, stream or wetland mitigation plan for this Site.
