Jones Street, Suite 3000 Raleigh, NC 27603 Re: Wingfoot – Task 9 - MY 5 Report (DMS Project No. 100078/DMS Contract 7607) Response to Comments Dear Mr. Dow, Please find below the response to comments on the Wingfoot Buffer Mitigation Monitoring Report provided by DMS dated January 23, 2024: 1.Section 2.0 – says that DWR viability letter is included in Appendix B. The viability letter is not included. Re: Complete. See attached viability letter at the end of Appendix B. 2.Please correct legal multiple legal citations that read “15 NCAC…” to “15A NCAC…” Re: 15 NCAC has been corrected to 15A NCAC throughout the report. 3.Section 3.2, paragraph 2 says the site was planted at approximately 538 stems/acre, but Section 4.3 the baseline was 666 stems/acre with a current planted stem density averaging 570 stems/acre (higher than the planted density referenced in Section 3.2). Please clarify. Re: The inconsistencies regarding stems/acre was clarified in Section 3.2. After construction, planted stems resembled 666 stems/acre rather than the 538 stems/acre described in the planting plan. 4.Final sentence in first paragraph of Section 4.3 says to “Refer to Figure 9…” for “proposed supplemental planting areas.” Figure 9 only shows supplemental planting that occurred in MY4. Please clarify. Clearwater Mitigation Solutions 604 Macon Place Raleigh, NC 27609 919-624-6901 clearwatermitigation@gmail.com Re: The final sentence in first paragraph of Section 4.3 was revised to read “Figure 9 (Current Condition Plan View) and Table 4 in Appendix B for additional information and previously supplemental planted areas.” Within the legend for Figure 9 - CCPV, the supplemental planting area is further distinguished by adding a “MY04 2022” label. 5. Please orient all Figures the same direction (horizontal) Re: All figures have been modified to ensure landscape orientation. 6. Figure 9 – an invasive treatment area is shown on the CCPV, but the report indicates that invasives were not treated in 2023. Please indicate in the legend the year the invasive treatment polygon represents, or remove. Additionally, we recommend adding indicating that the Riparian Habitat Corridor is “Not for Credit” in the legend. Re: The polygon representing the previously implemented invasive treatment was removed from CCPV (Figure 9). The label distinguishing the Riparian Habitat Corridor has been modified to include “Not for Credit” and is displayed on Figure 9. 7. Please fix Appendix B title page text. Please orient the photo pages horizontally. Re: The title page for Appendix B has been corrected and the photo pages have been reoriented. 8. Per recent requests from DWR, please include individual veg plot stem locations and height/vigor to Appendix B. Field sheets are acceptable.

Vegetation Data & Viability Letter Wingfoot Riparian Buffer Mitigation Site – Monitoring Report (MY5) 1 | Page DMS Project No. 100078 February 9, 2024 1.0 Mitigation Project Summary The Wingfoot Riparian Buffer Restoration Project (“the Site”) is a buffer restoration project located in Pitt County, approximately three (3) miles southeast of Farmville, NC and east of State Route 1139 (Moye Turnage Road) (Figure 1). The Site is comprised of 22.31 acres and is located within the Little Contentnea Creek TLW of the Neuse River (Figures 2 & 3). The buffer restoration and enhancement areas are located along unnamed tributaries (UTs) and drainages that flow directly into Little Contentnea Creek approximately 0.3 miles downstream (Figures 3-5). The Site is surrounded by areas managed for agricultural production (corn, cotton, and soybean) and prior to the project completion lacked existing forested buffer along a majority of the streams and drainageways dissecting the site. The Site is expected to generate 541,415.369 riparian buffer credits (BMU). The Site is located within Hydologic Unit Code (HUC) 03020203070030 and North Carolina Department of Water Resources (NC DWR) Sub-Basin 03-04-07. Four (4) unnamed tributaries on the Site flow into Little Contentnea Creek (Reach A1, B1-B3). Little Contentnea Creek is a 303d-listed impaired waterbody with a NC DEQ surface water classification of C; Sw, NSW. 1.1 Project Goals The main goals of the project are to provide water quality and ecological enhancements to the Little Contentnea Creek watershed of the Neuse River basin by creating a riparian corridor and restoring the historic riparian buffer. The project addresses the watershed goals identified in the Neuse River Basin Restoration Plan (RBRP) (NC EEP, 2010). These goals include: ● Promote nutrient and sediment reduction in agricultural areas by restoring and preserving wetlands, streams, and riparian buffers; ● Promote re-establishment of riparian corridors of substantial width to improve connectivity of protected lands; and ● Support implementation of Coastal Habitat Protection Plan (CHPP) strategies. These watershed goals have been achieved via the restoration and enhancement of woody buffer along unnamed tributaries of the Little Contentnea Creek (a 303d-listed impaired waterbody). Specific objectives of the project which achieved the desired goals included: ● Conversion of existing agricultural fields into wooded riparian buffer zones along existing tributaries via planting of characteristic hardwood species; ● Enhancement of degraded buffer areas (in areas of fields laid to fallow) via planting of characteristic hardwood species; ● Ensuring diffuse flow throughout the riparian buffer zone; ● Establishment of a conservation easement to protect the riparian buffer restoration site in perpetuity and to connect to existing DMS protected site; and ● Invasive species management during the monitoring period. Wingfoot Riparian Buffer Mitigation Site – Monitoring Report (MY5) 2 | Page DMS Project No. 100078 February 9, 2024 Ancillary benefits of the project include: • Increase of organic material as food for invertebrates, fish and wildlife; • Supply of woody debris that provides increased niche habitat for fish, invertebrates and amphibians; • Reduction of sunlight reaching the stream and modulation of surface water temperatures; • Floodwater attenuation via temporary storage, interception and slow releases from heavy rains; and • Habitat connectivity between currently protected riparian buffer areas (NC DMS Fox Run Site) and downstream riverine swamp forest via a protected riparian habitat corridor (including expansion of refuge and foraging habitat). 1.2 Pre-construction Site Conditions The project includes 22.31 acres of mostly open agricultural fields along four (4) unnamed tributaries to Little Contentnea Creek. The Site has historically been managed for agricultural production (corn, cotton, and soybean). Site drainage and hydrology have been historically altered with channelized streams and cleared agricultural lands prevalent on historic aerial photos dating back to the 1940s. The majority of the Site has been cleared as recent as 1998 (Figure 6) with some areas revegetating in recent years (Figure 7). The Site consists of four reaches (A1, B1, B2, and B3) as illustrated in Figures 8A and 8B. Reach A1 is a perennial stream located on the northern boundary of the site and is contiguous with the existing NC DMS buffer project easement (Fox Run). Reach A1 flows from the NC DMS easement on the northwestern boundary to the north and into Little Contentnea Creek approximately 1,800 lf downstream. There is approximately 850 lf of stream associated with Reach A1 within the proposed buffer easement area. The upper portion of Reach A1 has been restored as a forested riparian buffer to 200-ft. The lower segment near the confluence with Reach B1 has been restored to 100-ft. Reach B1 is the perennial stream that dissects the central portion of the site. It drains into Little Contentnea Creek (approximately 1,300 lf downstream from the eastern property boundary). There is approximately 2,690 lf of stream channel associated with Reach B1 within the proposed buffer easement area. The cleared portion of Reach B1 has been restored to 100-ft. A small area along the north side has been enhanced by establishing woody stems to 100-ft. The remaining portion of the reach near the confluence with Reach A1 and along the north side of the reach (extending east to the property line) has re-vegetated in past years and has been preserved. Reaches B2 and B3 flow into Reach B1 from smaller drainage areas on the southern portion of the site. Reach B2 is partly an intermittent stream consisting of approximately 210 lf of stream channel and partly a non-stream tributary of approximately 385 lf of channel. Reach B3 is a non-stream tributary that flows directly into reach B2 and consists of approximately 420 lf of channel. The first 50-ft from these tributaries have been restored. The project attributes are listed in Table 1, located in Appendix A. Wingfoot Riparian Buffer Mitigation Site – Monitoring Report (MY5) 3 | Page DMS Project No. 100078 February 9, 2024 2.0 Determination of Credits On August 30, 2018, Ms. Katie Merritt of the Division of Water Resources (DWR) performed an evaluation of surface water features and adjacent riparian areas within the proposed mitigation site for the determination of riparian buffer mitigation pursuant to 15A NCAC 02B .0295 (effective November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0240 (refer to attached Site Viability Letter, Appendix B). Based upon this evaluation, DWR determined that areas within 200 ft of Reach A-1 and Reach B-1 are eligible for both buffer restoration credit and nutrient offset credit (with the latter eligible in non- forested fields only). Riparian areas along Reach B-2 and B-3 are eligible for nutrient offset. In addition, the downstream segment of B-2 is eligible for buffer restoration credits. In addition to buffer restoration on subject streams, per the Consolidated Buffer Mitigation Rules (15A NCAC 02B 0.0295 (o)), alternative mitigation is proposed on the site in the form of: 1) preservation of buffers on subject streams and, 2) restoration and enhancement on ditches. The project is in compliance with these rules as it meets the following criteria: Preservation on Subject Streams (15A NCAC 02B 0.0295 (o)(5)): (A) The buffer width is at least 30 feet from the stream; (B) The area meets the requirements of 15A NCAC 02R 0.0403(c)(7), (8), and (11) with no known structures, infrastructure, hazardous substances, soild waste, or encumbrances within the mitigation boundary; (C) Preservation mitigation is being requested on no more than 25% of the total buffer mitigation area (Table 2, Appendix A) Restoration and Enhancement on Ditches (15A NCAC 02B 0.0295 (o)(8)): Reach B-3 and the upstream segment of Reach B-2 were determined to be conditionally eligible for buffer credit value provided that the watershed drainage area is of sufficient size to meet the rule criteria per 15A NCAC 02B .0295 (o)(8). Note that the ditches proposed for buffer restoration meet the following criteria: (A) are directly connected with and draining towards an intermittent or perennial stream; (B) are contiguous with the rest of the mitigation site protected under a perpetual conservation easement; (C) stormwater runoff from overland flow shall drain towards the ditch (Not Applicable); (D) are between one and three feet in depth; and (E) the entire length of the ditches have been in place prior to the effective date of the applicable buffer rule. Wingfoot Riparian Buffer Mitigation Site – Monitoring Report (MY5) 4 | Page DMS Project No. 100078 February 9, 2024 F) The buffer width is at least 30 feet from the stream Similarly, in accordance with Subparagraph (o)(8), the perpetual conservation easement includes the ditch and the confluence of the ditch with the stream. The easement includes language prohibiting future maintenance of the ditch. In addition, the watershed draining to the ditch is at least four times larger than the restored or enhanced area along the ditch. The watershed draining to the upper end of Reach B-2 is approximately 782,392 sf (relative to a corresponding buffer area of 32,671 sf). The watershed draining to Reach B-3 is approximately 312,499 sf (relative to a corresponding buffer area of 35,609 sf). There are no known site constraints that would impede or adversely affect the restoration, enhancement, and preservation of riparian buffer within the recorded easement area. Diffuse flow of runoff will be maintained in the riparian buffer except where the upstream portions of non-subject ditch segments of B2 and B3 enter the buffered area. Where such diffuse flow cannot be attained in these areas and where NCDWR agrees that such treatment of stormwater is not possible, deduction of credit has been calculated and applied following guidance of Buffer Interpretation/Clarification Memo #2008-019. In these upstream areas, an immediate drainage area equaling 0.10-acre from the point of discharge has been used to calculate the area of buffer being short-circuited by the ditch. Since the upstream origin of the ditch is not buffered, the credit deduction has been applied to the most upstream portion of the ditch on the Site. Mitigation credits are presented in Table 2 and Figure 8A/8B in Appendix A and are based upon the conservation easement survey included in Appendix C. 3.0 Baseline Summary The project team restored high quality riparian buffers along all unnamed tributaries within the Site. The project design ensured that no adverse impacts to wetlands of existing riparian buffers occurred during implementation. Refer to Figure 8A/8B for the conceptual design of the project. Details of the restoration activity that occurred follows in the sections below. Refer to site photos in Appendix D. 3.1 Planting Preparation Based upon pre-project assessment of compaction within the proposed planting areas, the project team identified two select areas of the buffer restoration project that warranted site disking (refer to Figure 7). The areas included an approximate 150-ft long area of the right top of bank of the upper end of Reach B- 1 and the riparian area of the right top of bank of Reach A-1 (including the area of field identified as the “Riparian Habitat Corridor”). These areas were disked prior to planting to reduce compaction and to enhance microtopography. In addition, selective mowing occurred within the riparian buffer enhancement area to limit blackberry and smaller, volunteer red maple (refer to Figure 7). This area was observed to contain a population of Japanese honey-suckle (Lonicera japonica) which was spot treated with herbicide. No other site preparation occurred. No observed drain tiles were observed prior to, or during, construction and planting and no other land disturbance was needed to maintain diffuse flow as required. Wingfoot Riparian Buffer Mitigation Site – Monitoring Report (MY5) 5 | Page DMS Project No. 100078 February 9, 2024 3.2 Riparian Area Restoration and Enhancement Activities Prior to planting, the conservation easement boundary was marked using 6-inch diameter treated posts buried 2 feet, standing 6 feet above the ground surface, within the agricultural fields. T-posts were installed to provide supplemental marking within areas between the treated posts, within the enhancement area, and within the preservation areas as needed. The easement boundary was also marked with standard yellow Conservation Area signs, per the 01/23/14 NCDMS Boundary Marking Standards. The planting plan consisted of the planting of four hardwood species and one softwood species on a density of approximately 538 stems per acre. This density was selected to be sufficient to meet performance standards outlined in the Rule 15A NCAC 02B .0295 of 260 trees per acre at the end of five years. After construction, the actual number of planted stems resembled 666 stems per acre rather than the 538 stems per acre described in the planting plan. Species selection and distribution were matched closely to micro-site hydrologic and edaphic conditions and include species characteristic of riparian buffer assemblages in the watershed and adjacent to the site. Species more tolerant of poorly drained soils (i.e. bald cypress and willow oak) were planted within lower landscape positions generally consisting of the Tuckerman soil series while species characteristically occurring in better drained soils will be planted in slightly higher convex landscape positions. The selected native trees are well-suited to the site- specific conditions of the property to promote high survivorship rates. No one tree species planted was greater than 50% of the established stems. Site planting was conducted on March 12-13th, 2019 by Superior Forestry Services, Inc. and supervised by project managers from both Clearwater Mitigation Solutions and Davey Resource Group. Table 3 summarizes the trees planted by species for the Wingfoot mitigation site. Table 3. Planting Plan1 1Note planted area includes approximate 1.0 acres of field included for riparian habitat corridor. While no credit is proposed for this area, it was planted per the same specifications (species density and composition) as those contained within final, approved mitigation plan. 2Cypress trees are conifers, but unlike most American softwoods, they are deciduous trees that shed foliage in the fall like hardwoods. Although cypress is a softwood, it grows alongside hardwoods and was selected as an appropriate species to be planted in the wetter parts of the site.

The preservation area will be protected in perpetuity under a conservation easement. 4.0 Annual Monitoring and Performance Criteria Annual Monitoring has been conducted during the growing season for a period of five years. The reports include all information required by DMS monitoring guidelines including photographs, plot locations, and documentation of existing species density and composition. Monitoring has been performed in accordance with the Consolidated Mitigation Buffer Rule (15A NCAC 02B .0295) and current DMS standards. The performance criteria for the Site follows approved performance criteria presented in the guidance documents outlined in the Consolidated Buffer Rule (15A NCAC 02B .0295). Performance criteria has been evaluated throughout the five-year post-construction monitoring. 4.1 Methods The final vegetative success criteria is the survival of 260 planted stems per acre in the riparian buffer at the end of the required monitoring period (Monitoring Year (MY05)). Native hardwood and native shrub volunteer species may be included to meet the final performance standard of 260 stems per acre. Vegetative monitoring included the establishment of eleven (11) permanent plots consistent with the Carolina Vegetation Survey (CVS) protocol Level 2 (version 4.2) (refer to Figure 9 for plot locations). Reference photos of the vegetation plots and Site were taken at each predetermined photo point location. Appendix B includes the monitoring year five (MY05) vegetation plot photographs and the planted and total stem counts. Any vegetative problem areas in the site are noted and reported in each monitoring report. Vegetative problem areas may include areas that either lack vegetation or include populations of exotic vegetation. Monitoring reports identify any contingency measures that may need to be employed to remedy site deficiencies. Permanent photo stations were established across the project area in order to document site stability for five years post construction. Markers were established and located with GPS equipment so that the same locations and view directions on the Site were photographed each year. Photo reference stations are shown on Figure 9. Visual assessments have been performed annually during the five-year monitoring period. Problem areas of vegetative health have been noted and areas of concern have been mapped, photographed, and documented in each subsequent annual monitoring report. Problem areas have been re-evaluated in each monitoring event. Wingfoot Riparian Buffer Mitigation Site – Monitoring Report (MY5) 7 | Page DMS Project No. 100078 February 9, 2024 4.2 Tables (MY05) vegetation plot photographs and the planted and total stem counts (Table 3) are included in Appendix B. 4.3 Results and Discussion (MY05) Annual monitoring (MY05) was conducted on September 26, 2023 by DRG staff. Overall, the Site has exceeded the required vegetative success criteria. An average stem density of 570 planted stems per acre was tallied across the site (approximately 86% of the recorded baseline (MY0) density (666 stems per acre)). Stem densities within individual monitoring plots range from 202 to 728 planted stems per acre. Planted stem counts within individual plots range from 5 to 18 stems with an average of 14 planted stems per plot. Ten different hardwood species were observed across the site, exceeding the minimum diversity criterion. All vegetation plots except plot 8 have met the MY05 success criteria and many planted stems have exhibited prolific growth during the first five years of monitoring. In previous years, trees were lost to Japanese honeysuckle strangulation. In MY05 all trees in Plot 8 from MY04 were accounted for. The Site has met the final success criteria in all but one plot. Refer to Figure 9 (Current Condition Plan View) and Table 4 in Appendix B for additional information and prior planted supplemental areas. Japanese Honeysuckle (Lonicera japonica) and Chinese Privet (Ligustrum sinense) were observed and limited to the vicinity of Plot 8 as documented in previous years. The remaining trees within Plot 8 appear to be unaffected by the continued presence of Japanese Honeysuckle and dense herbaceous coverage. The remaining six trees continued to demonstrate growth and displayed an excellent vigor. This is the first year throughout the monitoring process where Plot 8 did not document any mortalities or planted trees characterized by low vigor. The remaining enhancement area of the site maintained relatively similar conditions to MY04. Refer to Appendix B for monitoring year five (MY05) vegetation plot photographs and the planted and total stem counts. 4.4 Maintenance and Management Overall, the vast majority of the Site has met the target success criteria. Small populations of invasive species were noted in the vicinity of Plot 8. Invasive conditions did not continue to permeate throughout Year 5 and treatments were not applied in the spring of 2023. Monitoring problem areas and invasive treatment areas at the site has been conducted for the required five years. Supplemental planting was conducted within a small area of low vigor trees at the upper end of the A1 reach in the early MY04 growing season. While this area was meeting required stem density, stem growth was noticeably less than the surrounding areas. For this reason, larger bare root stems were planted in this area. Approximately (100) 4-ft bare root stems consisting of river birch, sycamore, and willow oak were planted throughout this area. The five required years of monitoring have been completed, and the site has met the performance standards in all but one plot. Upon review and approval of this final monitoring report by NCDMS and NCDWR, we respectfully request closeout of the Site.
