In Year 5, 21 of the 21 vegetation plots met the 260 stems per acre interim success criteria and greater than an average 7 feet. Bankfull events were recorded on both stage recorders. In addition to the three wetland gauges installed in February 2022 (GW1-B, GW4-B, and GW7-B), two more wetland gauges were installed (GW5-B and GW7-C) in February 2023 to gather more hydrology data in underrepresented wetland areas. There are now 17 wetland gauges in total. In MY5, 12 of the 17 wetland gauges met success with hydroperiods ranging from one to 39 percent. Groundwater Wells 1, 4, 7, and Reference 1 have all failed to meet successful hydroperiods for the fifth year in a row. However, four of the five newer wetland gauges (installed since February 2022) were successful in MY5. Additional analysis of the wetlands at risk can be found in the MY5 monitoring report and Appendices. Data supports the success of at least 10.153 WMUs at this time, more than the 7.200 WMU credits that have already been released, leaving 2.953 WMU viable credits available. Furthermore, RES feels strongly that even more wetland areas will ultimately be successful and be deemed viable for credit generation. Two vegetation problem areas onsite include areas of low stem density (0.3 acres total) and areas of loblolly pine. There is one segment of stream channel (at cross section 17; reach S11) that shows signs of some degradation. No problems were identified in the field during monitoring; however, RES will investigate in the winter when vegetation has died and there's better visibility. The repairs (completed in August 2022) from the adaptive management plan remain in good condition and impacted stream banks were live staked February 2023 and are growing. RES performed supplemental plantings between January and March 2023 in two areas. In February and March, the areas associated with the adaptive management plan work performed on reach S6B and surrounding areas within wetland WG were planted with approximately 160 three-gallon containerized trees. In January, a small area in an around VP18 was planted with approximately 15 six-foot live stake poles. Consequently, Vegetation Plot 18 met success for MY5. Chinese privet in select areas was treated again in August 2023. The identified areas of low stem density will be planted in the coming winter, and areas of loblolly pine will be thinned in the following monitoring year; these areas can be seen on Figure 2; Appendix B. 2 NC IRT MY4 Review Comments: Casey Haywood, USACE: 1. Thank you for providing photos of the AMP repair work. Please continue to monitor these areas for any instability. Overall, the repairs look good. The repairs remain in good condition with functioning structures and stable banks. Repaired stream banks were live staked in February 2023 and are growing while herbaceous vegetation has also established in graded areas. 2. We have concerns regarding the performance of wetlands on the site (Wetland H and I). While low hydroperiods can be partially attributed to below normal rainfall conditions, gauges 1, 4, 5 and 7 have failed to meet performance standards in any of the previous years. Additionally, more data is needed to assess areas where the additional gauges were installed, in particular gauges GW4-B and GW7-B. We would like to schedule a site visit later this year to evaluate site conditions and see the repair work. It is clear that some of the wetland areas are not meeting success, such as those in proximity to GW1, GW4, and GW7. However, data supports the potential success of other questionable wetland areas, especially with the addition of five more wetland gauges (three of which were installed in February 2022 and two in February 2023). Four out of five of these had successful hydroperiods in MY5. Also of note, GW5 recorded its first successful hydroperiod (14%) for the first time. The MY5 report discusses the wetland findings and at-risk concept in detail. RES welcomes a site visit this year. RES is requesting a 10% stream credit release (544.00 SMUs). Additionally, RES is requesting that the past two years’ scheduled Wetland Credits of 15% (Year 3 Monitoring) and 5% (Year 4 Monitoring) credit releases be released based on the revised estimate of total Wetland Mitigation Units (10.15 WMU) which would result in a 1.43 credit release. As for the completion of the Year 5 monitoring report, RES expects that the 15% wetland credit release may be withheld. Please see enclosed the credit release schedule and an updated credit ledger.

Summary of Groundwater Monitoring Results MY5 Groundwater Hydrographs Figure 3: Wetland Risk Areas Meadow Spring 1 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 1 PROJECT SUMMARY 1.1 Project Location and Description The Meadow Spring Mitigation Site (Site) is located within a watershed dominated by agricultural land use in Johnston County, North Carolina, approximately three miles north of Smithfield. The project streams and wetlands were significantly impacted by channelization, impoundment, and cattle access. The project involves the restoration and protection of streams in the Neuse River watershed and the restoration, enhancement, and preservation of adjacent riparian wetlands. The purpose of this mitigation site is to restore, enhance and preserve a stream/wetland complex located within the Neuse River Basin. The Site was designed in concurrence with the Meadow Spring Riparian Buffer and Nutrient Offset Mitigation Bank. The Site lies within USGS Hydrologic Unit Code (HUC) 03020201. The total easement area is 60.93 acres. The wooded areas along the easement corridor designated for restoration activities are classified as mixed hardwoods. Invasive species were present throughout the wooded areas. Restored channels were both laterally and vertically unstable, impacted by cattle, have disturbed riparian buffers, and did not fully support aquatic life. Previous stream conditions along the restoration reaches exhibited habitat degradation because of impacts from livestock and impoundment to promote agricultural activities. The Meadow Spring Site includes stream Priority I/II Restoration, Enhancement Levels I II and III, Preservation and wetland re-habilitation, re-establishment, enhancement and preservation. Priority I Restoration reaches incorporate the construction of a single-thread meandering channel, with parameters based on data taken from the reference site described above, published empirical relationships, NC Coastal Plain Regional Curves, and hydrologic and hydraulic analyses. Wetland re-establishment occurred adjacent to Priority I Restoration reaches. The restoration approach was to reconnect the floodplain wetlands to the stream, fill existing ditches, rough the floodplain surface, and plant native tree and shrub species commonly found in small stream swamp ecosystems. The wetland enhancement treatment included livestock exclusion, improving hydrology via pond removal and ditch plugging, and planting native tree and shrub species. The Site will be monitored on a regular basis and a physical inspection of the Site will be conducted at a minimum of twice per year throughout the seven-year post-construction monitoring period, or until performance standards are met. These site inspections will identify site components and features that require routine maintenance. The measure of stream restoration success will be documented by bankfull flows and no change in stream channel classification. Sand bed channels are dynamic and minor adjustments to dimension and profile are expected. The measure of vegetative success for the Site will be the survival of at least 210 seven-year old planted trees per acre with an average height of 10 feet at the end of year seven of the monitoring period. Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to the North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will be responsible for Meadow Spring 2 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 periodic inspection of the Site to ensure that restrictions required in the Conservation Easement or the deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions will be negotiated prior to site transfer to the responsible party. 1.2 Project Goals and Objectives The 2010 Neuse RBRP identified several restoration needs for the entire Neuse River Basin, as well as for HUC 03020201, specifically. The Site is in HUC 03020201100050 (Neuse River), a Targeted Local Watershed (TLW) that exhibits both the need and opportunity for wetland, stream, and riparian buffer restoration. The watershed includes 52 square miles of area, with 31 percent of the 106 stream miles lacking wooded buffers. Thirty-seven percent of the watershed is used for agricultural purposes with 13 animal operations occurring in the watershed. Impervious surface near the town of Smithfield is increasing and set to surpass the critical seven percent benchmark (NCDMS 2010). The Site was identified as a stream and buffer restoration opportunity to improve water quality, habitat, and hydrology within the Neuse River Basin. This project is intended to provide Stream Mitigation Units to be applied as compensatory mitigation for unavoidable authorized impacts to waters of the US under Section 404 of the Clean Water Act (33 U.S.C. 1344) and support the overall goal of “no net loss” of aquatic resources in the United States. The Site is located within the downstream end of HUC 03020201 and includes an unnamed tributary that directly discharges into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in-stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. The project goals will be addressed through the following project objectives:  Design and construct stable stream channels with appropriate pattern, dimension, and profile based on reference reach conditions.  Exclude livestock permanently from streams and their associated buffers as well as surrounding wetlands.  Reduce bank height ratios to less than 1.2 and increase entrenchment ratio to greater than 2.2 in accordance to the Wilmington District Stream and Wetland Compensatory Mitigation Update Guidance.  Increase forested riparian buffers to at least fifty feet on both sides of the channel along the project reaches with an appropriate riparian plant community.  Re-establish, rehabilitate, and enhance riparian wetlands by raising stream bed elevations, plugging surface ditches, and planting native wetland plant species in order to maintain appropriate soil series saturation/hydroperiod thresholds during the growing season.  Preserve and enhance of hydrology in existing riparian wetland seeps.  Establish a permanent conservation easement on the Site. Meadow Spring 3 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023  Remove invasive species from the riparian buffer and wetland areas to support the colonization and survival of native riparian buffer species. 1.3 Project Success Criteria The Site follows the USACE 2003 Stream Mitigation Guidelines and the “Wilmington District Stream and Wetland Compensatory Mitigation Update” dated October 24, 2016. Cross section and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Stream and wetland hydrology data and visual monitoring will be reported annually. 1.3.1 Stream Success Criteria Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull events have been documented in separate years. There should be little change in as-built cross-sections. If changes do take place, they should be evaluated to determine if they represent a movement toward a less stable condition (for example down-cutting or erosion), or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross sections shall be classified using the Rosgen stream classification method, and all monitored cross-sections should fall within the quantitative parameters defined for channels of the design stream type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 2.2 within restored reaches. Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should not indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A series of images over time should indicate successional maturation of riparian vegetation. 1.3.2 Wetland Success Criteria The Natural Resources Conservation Service (NRCS) has a current WETs table for Johnston County upon which to base a normal rainfall amount and average growing season. The closest comparable data station was determined to be the WETS station for Smithfield, NC. The growing season for Johnston County is 233 days long, extending from March 18 to November 6, and is based on a daily minimum temperature greater than 28 degrees Fahrenheit occurring in five of ten years. Based upon field observation across the site, the NRCS mapping units show a good correlation to actual site conditions in areas of the site. Mitigation guidance for soils in the Coastal Plain suggests a hydroperiod for the Bibb soil of 12-16 percent of the growing season. The hydrology success criterion for the Site is to restore the water table so that it will remain continuously within 12 inches of the soil surface for at least 12 percent of the growing season (approximately 27 days) at Meadow Spring 4 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 each groundwater gauge location. Based on the extensive management history of the Site and soil compaction, RES expects a slightly reduced hydroperiod in the monitoring years 1 and 2. 1.3.3 Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the site follow IRT Guidance. Vegetation monitoring plots are a minimum of 0.02 acres in size and cover a minimum of two percent of the planted area. Vegetation monitoring shall occur annually between July 15 and leaf drop. The interim measures of vegetative success for the site are the survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 five-year old trees that are at least 7 feet tall at the end of Year 5, and the final vegetative success criteria is 210 trees per acre with an average height of ten feet at the end of Year 7. Volunteer trees are to be counted, identified to species, and included in the yearly monitoring reports, but do not count towards the success criteria of total planted stems. 1.4 Project Components The project area is comprised of an easement area along an unnamed tributary to the Neuse River. The easement is separated by an existing power easement and three agricultural crossings. The project is divided into northern and southern portions by the existing power easement. The northern portion of the project includes Reaches S1, S2, S5, S6A and S6B. The southern portion of the project includes Reaches S7, S9, S11, S12 and S13. The stream and wetland mitigation components are summarized below.

Priority I Restoration reaches incorporate the design of a single-thread meandering channel, with parameters based on data taken from the reference site described above, published empirical relationships, NC Coastal Plain Regional Curves, and hydrologic and hydraulic analyses. As a result of the restoration of planform and dimension, frequent overbank flows and a restored riparian buffer will provide the appropriate hydrology and sediment transport throughout this coastal plain watershed. All non-vegetated areas within the easement were planted with native vegetation and any areas of invasive species were removed and/or treated.  Reach S1 (STA 03+50 to STA 06+00) – Reach beginning at northwestern limits of the project flowing southeast to Reach S2 totaling 250 linear feet of Enhancement Level II. Row crops and active pasture were located adjacent to the reach. Enhancement involved revegetating the buffer with native vegetation.  Reach S2 (STA 06+00 to STA 11+00) – Reach begins at the downstream end of Reach S1 and flows southeast through what was active pasture to Reach S6A. Reach S2 totals 500 linear feet of Enhancement Level I. Active pasture and row crops used to surround this reach. Enhancement involved revegetating the buffer and stream stabilization of localized erosion with the installation of log cross vanes and sills.  Reach S5 (STA 00+76 to STA 03+07) – Reach begins north of Reach S6A and flows south through active pasture to a confluence with Reach S6A totaling 231 linear feet of Priority I and II Restoration. Active pasture and maintained lawn used to surround this reach. Restoration included meandering the channel within the valley, backfilling the old stream, reconnecting to its floodplain, and restoring hydrology to drained wetlands. Meadow Spring 6 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023  Reach S6A (STA 11+00 to STA 24+50) – Reach begins at the downstream end of Reach S2 and flows east through what was active pasture, flows adjacent to a farm pond and ends at a confluence with Reach S5. Reach S6A totals 1,350 linear feet of Priority I Restoration. Restoration included meandering channel though the natural valley, backfilling the old channel, reconnecting to its floodplain, removing the old dam, and restoring hydrology to drained wetlands.  Reach S6B – Section 1 (STA 24+50 to STA 36+26) – Reach begins at the confluence of Reach S5 and S6A flowing east to the second section of Reach S6B. Reach S6B-Section 1 totals 1,176 linear feet of Priority I Restoration. Restoration included meandering the channel within the valley, backfilling the old stream, reconnecting to its floodplain, and restoring hydrology to drained wetlands.  Reach S6B – Section 2 (STA 36+26 to STA 37+93) – Reach begins at the downstream end of Reach 6B-Section 1 and flows east to the Duke Energy right-of-way. Reach S6B- Section 2 totals 167 linear feet of Enhancement Level I. Enhancement included stabilization of localized erosion by installing log sills, increasing radius of curvature, regrading point bars, removal of invasive vegetation, and revegetating the buffer.  Reach S7 (STA 38+80 to STA 53+80) – Reach beginning downstream of the Duke Energy right-of-way and flows south to Reach S9 totaling 1,430 linear feet of Enhancement Level I. A 70-linear foot easement break is located in this reach to accommodate a proposed farm crossing. Hardwood forests and active pasture are located adjacent to the reach. Enhancement included stabilization of localized erosion by installing log vanes, log sills, brush toes, and regrading point bars. As well as removing dense areas of invasive vegetation and supplementing planting in its place.  Reach S9 (STA 53+80 to STA 60+55) – Reach beginning at the downstream end of Reach S7 and flowing south to Reach S11 totaling 675 linear feet of Enhancement Level III. Hardwood forests and active hog lagoons are located adjacent to the reach. Enhancement included invasive treatment and supplemental planting.  Reach S11 (STA 60+55 to STA 71+00) – Reach beginning at the downstream end of Reach S9 and flows southeast to Reach S12 totaling 1,045 linear feet of Priority I Restoration. Hardwood forests and grassed fields were located adjacent to the reach. Restoration included meandering the channel within the valley, backfilling the old channel, reconnecting to its floodplain, and improving hydrology to drained wetlands.  Reach S12 (STA 71+00 to STA 74+80) – Reach beginning at the downstream end of Reach S11 and flows southeast toward the Neuse River floodway totaling 380 linear feet of Preservation. Hardwood forests are located adjacent to the reach. Preservation included invasive treatment and buffer/stream protection.  Reach S13 (STA 9+69 to STA 14+23) - Reach beginning downstream of the large wetland slough along the Neuse River floodplain totaling 454 linear feet of Preservation. Preservation included invasive treatment and buffer/stream protection. Meadow Spring 7 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 1.5.2 Wetland The Meadow Spring Site offers a total ecosystem restoration opportunity. As such, the wetland restoration and enhancement are closely tied to the stream restoration. The Site provides 14.41 WMUs through a combination of wetland re-establishment, rehabilitation, and enhancement. Because of the sites observed soil characteristics and landscape position, a combination of wetland re-establishment, rehabilitation, and enhancement was incorporated. In wetlands WH, the non-jurisdictional area, hydrologic restoration, at a credit ratio of 1:1, was accomplished by plugging the existing incised channel to restrict drainage and allowing a natural hydroperiod to return. In addition, re-constructing a stream channel at a higher bed elevation in the natural valley, backfilling to create shallow depressions within the old channel, and the removal of spoil from pond excavation along the floodplains aids in the restoration of a natural floodplain surface relative to the surrounding landscape. Due to compaction and long-term agricultural use, a shallow ripping of the surface along the contour to a depth of eight to ten inches creates adequate porosity for infiltration and storage, provides microtopographic relief, and should improve vegetative survival and growth. As part of the wetland re-establishment in wetland WI, at a credit ratio of 2:1, the pond was removed. The construction of a farm pond has altered surface drainage and placed spoil across the floodplain. The stream was reconnected to the floodplain and in addition to out of bank events the large perennial spring serves as a source for hydrology for the re-established wetlands. Retention and storage within the floodplain has returned to a natural state having an increased hydroperiod. In wetland WF-B, a credit ratio of 3:1 was implemented for wetland enhancement. This wetland has been impacted by channel incision and active management for agriculture in the past. The wetland mitigation treatment consisted of reconnecting the stream to the floodplain and replanting disturbed areas. These activities result in a much healthier, better functioning wetland. In wetland WG, the large disturbed Neuse River floodplain area, a credit ratio of 3:1 was implemented for wetland enhancement in the areas that are planted (WG-A) and an enhancement credit ratio of 5:1 in the areas not planted (WG-B). This wetland has been actively managed for agriculture and waterfowl through drainage manipulations and tree clearing. The wetland mitigation treatment was primarily re-planting the disturbed areas, plugging the main ditch, and removing existing berms within the wetland. These activities result in a large floodplain slough with a diversity of microhabitats. 1.6 Construction and As-Built Conditions Stream construction and planting was completed in June 2019. The Meadow Spring Mitigation Site was built to design plans and guidelines. A redline version of the as-built survey is included with the sealed plat in the As-Built Baseline Monitoring Report. Project credits are based on design centerline, but as-built stream lengths are shown on Table 1. Meadow Spring 8 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 1.7 Wetland Risk Upon completion of the year three monitoring and report submittal, the IRT declined to release the associated wetland credits due to concerns related to the wetlands on site. Four of 11 wetland gauges had not met the performance criteria for all three years they’d been installed. After an evaluation of wetland conditions on site, a general wetland delineation of areas surrounding the at-risk wells (performed on February 10, 2022), and an analysis of hydrology data, it was concluded that approximately 1.80 acres of wetlands were at risk of not meeting successful performance criteria, at that time. Wetland H (WH) and Wetland I (WI), on the western side of the project, were the two wetlands with a number of unsuccessful gauges. Upon completion of the year four monitoring and report submittal, the IRT again declined to release the associated wetland credits due to concerns related to the wetlands on site. Again, four of the original 11 wetland gauges had not met the performance standard in any of the four years they’d been installed, and two of three supplemental gauges failed to meet success criteria in MY4. However, this was a difficult year to make a determination as it was well cited across the state that the state was in a drought. Now, in monitoring year five, it is clear that some previously determined, at-risk wetland areas are still not meeting the wetland hydrology performance standard. However, three gauges which failed last year are successful in MY5. In addition, two more gauges were added in February 2023 to further investigate and validate success of other wetland areas. Both of these new gauges were also successful. Therefore, RES suggests that some of the wetland areas which were determined to “need more information” before concluding their success and ultimate credit generation, are performing well and present a positive outlook. Ultimately, more data is still needed for such areas, but eventually a wetland evaluation where the at-risk wetland boundaries and questionable areas will be refined based on previous analysis and current and future supporting gauge hydrology data. At this time though, RES still presents that 2.069 acres (2.069 WMUs) of wetlands are at risk of not meeting final performance standards, while the remaining wetland areas, especially those represented by newer wetland gauges, will continue to be monitored closely. Additional details regarding the results and future outlook of these areas are described in Section 1.8: Wetland Hydrology. 1.8 Year 5 Monitoring Performance (MY5) The Meadow Spring Year 5 Monitoring activities were performed in June and September 2023. All MY5 data is present below and in the appendices. The Site is on track to meeting vegetation and stream interim success criteria while wetland interim success criteria is being met for most wetland areas but not all. 1.8.1 Vegetation Monitoring of the 18 permanent vegetation plots and three random vegetation plots was completed during September 2023. Vegetation data are in Appendix C, associated photos are in Appendix B, and plot locations are in Figure 2; Appendix B. MY5 monitoring data indicates that Meadow Spring 9 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 21 of the 21 plots are exceeding the interim success criteria of 260 planted stems per acre. Planted stem densities ranged from 324 to 850 planted stems per acre with a mean of 624 planted stems per acre across all the plots. A total of 20 planted species were documented within the plots. The average height of all trees in the plots was 9.7 feet, which is well above the interim success criteria of an average of seven feet tall at year five. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. Most of the loblolly pine (Pinus taeda) denoted in last year’s monitoring report were treated in August 2023 as well as several newly identified areas. However, more pine was identified during MY5 monitoring and will be treated in the coming year (Figure 2; Appendix B). Also of note, additional areas of Chinese privet on the western side of the site were also treated in August 2023 (Figure 2; Appendix B). Two small areas were determined to have low-stem density with a combined total area of about 0.3 acres. One area is located around VP9 and the other extends from a portion of WB into the southern extent of WH generally along a segment of the plugged ditch there (Figure 2; Appendix B). RES intends to perform supplemental planting in the areas in the coming winter. Visual assessments of the easement boundary found no encroachments or evidence of cattle entry. RES performed supplemental plantings between January and March 2023 in two areas. In February and March, the areas associated with the adaptive management plan work performed on reach S6B and surrounding areas within wetland WG were planted with approximately 160 three-gallon containerized trees. Species included swamp chestnut oak (Quercus michauxii), overcup oak (Quercus lyrata), river birch (Betula nigra), buttonbush (Cephalanthus occidentalis), and American sycamore (Platanus occidentalis). In January, a small area in an around VP18 was planted with approximately 15 six-foot live stake poles. Species included black willow (Salix nigra) and buttonbush (Cephalanthus occidentalis). Consequently, VP18 met success for MY5. Furthermore, RES placed another Random Vegetation Plot (RVP3) directly adjacent to VP18, and it also exceeded success criteria. Supplemental planting locations are depicted in Figure 2; Appendix B. 1.8.2 Stream Geomorphology Geomorphology data for MY5 was completed in June 2023. Summary tables and cross section plots are in Appendix D. Overall, the MY5 cross sections relatively match the as-built conditions with the exception of some adjustments in several cross sections over the years. The following summarizes pertinent details for select cross sections:  Cross section 2 (Riffle) (Enhancement I) – Bed elevation has fluctuated up and down within one foot over the years and was at its deepest in MY2.  Cross section 4 (Pool) (Restoration) – Significant increase in channel dimensional area after MY0 but then stabilized with little change since then.  Cross section 7 (Riffle) (Restoration) – Bed deepened about three-quarters of a foot after MY0 but then stabilized with little change since then.  Cross section 8 (Pool) (Restoration) – Bed deepened about three-quarters of a foot after MY0 but then stabilized with little change since then. Meadow Spring 10 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023  Cross section 16 (Riffle) (Enhancement I) – This cross section is located within an adaptive management plan repair segment of reach S7. The right pin was damaged during construction, but a new pin was installed but not surveyed into real geographic coordinates. Therefore, the MY5 line plotted in the Overlay Plots (Appendix D) may not perfectly depict a true overlay with previous years. However, the channel dimension depicted does show the result of the stream repair, especially along the right bank where the channel was slightly benched and the bank smoothed.  Cross section 16b (Pool) (Enhancement I) – This is a new cross section below cross section 16 that was installed and surveyed to document channel dimension of the pool just below the repaired log sill on reach S7.  Cross section 17 (Riffle) (Restoration) – Dimension has widened progressively since MY1. The bank height ratio is now approximately 1.5 though entrenchment ratio is about 7.1. The cross section shows degradation, and RES suspects there could be erosion associated with the left side of the log sill just below. No problems were identified in the field during monitoring; however, RES will investigate in the winter when vegetation has died and there's better visibility. Any potential problem appears isolated as the pool cross section just below (XS18) appears stable and the next pair of cross sections located downstream on S11 also appear stable.  Cross section 18 (Pool) (Restoration) – Bed elevation rose about a foot after MY0 but has since stabilized and fluctuates a few inches over the years. Typical pool dynamics.  Cross section 19 (Riffle) (Restoration) – Bed elevation was consistent between MY0-MY2 and then rose about three-quarters of a foot in MY3 and did not change in MY5.  Cross section 20 (Pool) (Restoration) – Bed elevation was consistent between MY0-MY1 and then rose about three-quarters of a foot in MY3, then rose another half-foot in MY3, but then did not change in MY5. Typical pool dynamics.  Cross section 21 (Pool) (Restoration) – Bed elevation was consistent between MY0-MY1 and then rose about a foot between MY2-MY3, but deepened another half-foot in MY5. Typical pool dynamics. Ultimately, bank height ratios remain less than 1.2 and entrenchment ratios greater than 2.2 on all riffles on restoration reaches besides that noted for cross section 17 on reach S11. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. Generally, the channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation. The repairs performed in August 2022 and in accordance with the Adaptive Management Plan appear successful and remain stable in MY5 with no associated problem areas to be reported. Of note, all repaired stream banks were live staked in February 2023 with tree material harvested onsite. As mentioned above, cross section 17 shows some degradation and the stream channel segment will be investigated during leaf-off conditions to determine if adaptive measures are needed. Meadow Spring 11 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 1.8.3 Stream Hydrology Two stage recorders were installed in June 2019 to document bankfull events. One stage recorder on Reach S6-B and one stage recorder on Reach S11. The stage recorder on Reach S6-B recorded three bankfull events in MY5 with the highest stage measuring 0.6 feet above top of bank, occurring on August 15, 2023. The stage recorder on Reach S11 recorded 9 bankfull events with the highest stage measuring 6.62 feet above top of bank, occurring on April 26, 2023. Reach S11 experiences extreme flooding from backwater of the Neuse River. Stage recorder locations can be found on Figure 2; Appendix B and associated data is in Appendix E. 1.8.4 Wetland Hydrology Following the general delineation conducted in February 2022, three groundwater wells were added to Wetlands I and H (WI and WH); each named for their proximity to existing groundwater wells: GW1-B, GW4-B, and GW7-B. The adjusted locations of the wells were chosen based on field observations made during the general delineation and were installed on February 24, 2022. In August 2022, as part of the approved AMP, a 150-foot-long plug was installed in the backwater slough that had become channelized along the northern portion of Wetland H, that runs parallel to reach S6-B. The plug is 50 feet wide and one-half foot high above top of bank. The downstream side of the plug is lined with Class B rip rap to stabilize potential over-plug flows. This plug was installed in an attempt to limit water from being diverted out of the wetland area and into the channelized slough. This plugged area was planted with 3-gallon container trees in February and March 2023. To gather and document hydrology for some other, unrepresented wetland areas, two additional wetland gauges were installed in February 2023. GW5-B was installed in the western portion of wetland WH and GW7-C was installed further upstream of GW7-B within WH. Twelve of the 17 groundwater wells met the 12 percent hydroperiod success criteria during MY5. The five that did not meet the 12 percent hydroperiod, including the reference well, had less than a five percent hydroperiod and have never met the success criteria to date. Overall, hydroperiods ranged from one to 39 percent in year five. As for the newer wetland gauges installed in February 2022, GW1-B recorded a 36 percent hydroperiod, GW4-B recorded a hydroperiod of three percent, and GW7-B recorded a 13 percent hydroperiod in their second season. As for the newest wetland gauges installed in February 2023, GW5-B recorded a hydroperiod of 14 percent and GW7-C recorded a hydroperiod of 13 percent in their first season. Additionally, GW5 (one of the original gauges) met the success criteria for the first time with a recorded hydroperiod of 14 percent. Updated groundwater well locations can be found on Figure 2 and the data is in Appendix E. The “Wetland Risk Map” (Figure 3) initially presented in the MY4 report has been updated to depict all wetland gauges and their current success status. Figure 3 is included along with the hydrology data in Appendix E. The map displays areas, specifically in the westernmost portion of the easement, that are at risk of credit loss due to consistently low hydroperiods or need more time and data before credit allocation takes place. The calls are as follows: Meadow Spring 12 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 All Rehabilitation (1.5:1) areas were successful: 0.636 credits All Enhancement (3:1; 5:1) areas were successful: 5.507 credits Parts of WI (Re-establishment, 2:1) were successful: 1.357 credits Parts of WH (Re-establishment, 1:1) were successful: 2.652 credits Total of 10.153 credits Wetlands WB, WF (A and B), WG (A and B):  All wetlands have met success and are not at risk of credit loss.  Groundwater well GW3 in Wetland B has been successful, recording hydroperiods ranging from 15-27 percent, for the last four consecutive years. This area around the well and surrounding areas, to the north (southwestern-most corner of WH), have displayed the same wetland characteristics throughout (i.e., hydrology, soils, vegetation) since the beginning of the Project; therefore, the southwestern portion of WH is considered successful as well and is not at risk of credit reduction. Wetland I (WI), Re-establishment (2:1): 2.85 acres:  GW1 recorded a 3% hydroperiod in MY5, a 4% hydroperiod in MY4, and 6-9% in previous years, (Table 13); but GW1-B, installed slightly upstream, displayed a 36% hydroperiod in MY5 and 20% hydroperiod in MY4. GW1 was installed on a terrace between the confluence of S2 and a perennial spring, but other wetland indicators still exist such as wetland soils and hydrophytic vegetation. It is possible that this location has shown more drainage effect from the open channels surrounding it than anticipated, or the wetland gauge (groundwater well) itself is malfunctioning such as improper installation, cracking, or penetrating a restrictive layer. Regardless, for the time being, the area around GW1 has been designated to “need more information” before making a decision about cutting credits permanently. If GW1-B continues to display appropriate hydrology, that will be considered when delineating areas of suitable wetland to remain. Wetland I has been divided, and portions of it, specifically a 0.14-acre area around GW1, are not included in the calculations for successful credit areas during Year 5; however, with more information and time, the original crediting amount will be considered for this wetland if the data warrants.  GW2 is considered successful, exceeding a 12% hydroperiod in all but one year (MY4), and displayed a 14% hydroperiod in MY5 (Table 13). This wetland gauge and surrounding area is not of concern, based on the past years’ hydroperiods and obvious wetland characteristics of the area (i.e. wetland vegetation surrounding well and groundwater seepage from the adjacent slope). Additionally, the area on the opposite bank shows the exact same characteristics and is also considered to be meeting success. Wetland H (WH), Re-establishment (1:1): 6.84 acres:  GW4 had shown improvement from MY1 to MY3 (with a hydroperiod increasing from 2%- 7%) (Table 13). However, there has not been improvement since then with 3% Meadow Spring 13 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 hydroperiods in both MY4 and MY5. Data from GW4-B, installed northeast of GW4 in February 2022, mimicked that of GW4 with only a 3% hydroperiod in MY5. Therefore, the general area surrounding GW4 and GW4-B is at-risk of not meeting the performance standard and is not included in the successful credit calculations for MY5. However, the Wetland gauges will continue to be monitored in following monitoring years.  GW5 was trending toward success with the hydroperiod improving from 2% in MY1 to 8% and 7% in MY2 and MY3, respectively; however, it recorded 3% in MY4 during a drought. This year, MY5, shows the positive trend continuing with a resulting hydroperiod of 14%. Generally, the area around it presents wetland characteristics like wetland vegetation and soils. GW5 is located on a slight terrace in between the new and old channels. Although the old channel has been backfilled, some drainage effects are still present as most surface flow is intercepted by the slight depression of the backfilled channel. This area, surrounding GW5, has been designated to “need more information.” However, RES feels that this area shows all signs that it will meet success criteria as a re-established wetland. In February 2023, RES installed an additional wetland gauge (GW5-B) upstream and to the west of GW5 to capture additional hydrology data. GW5-B also documented a 14% hydroperiod for MY5 and is in an area that also exhibits other wetland characteristics, like GW5. Based on current information, RES there is strong likelihood that some or all of the wetland area represented by GW5 and especially GW5-B may ultimately be included for credit. For the time being, this area will not be considered in successful credit calculations for MY5; however, the groundwater wells will continue to be monitored to hopefully document improving hydrology in following monitoring years.  GW7 remained unsuccessful in MY5 for the fifth consecutive year. However, GW7-B was successful in MY5, now its second year after being installed, displaying a hydroperiod of 13%. A few factors could have played a role in this area’s performance in MY5, including the slough to the north that was diverting water has now been plugged since of August 2022 and a more normal year of rainfall. In February 2023, RES installed an additional wetland gauge (GW7-C) upstream and to the northwest of GW7-B to capture additional hydrology data in an otherwise unrepresented area of wetland WH. Like GW5-B, GW7-C also documented a 13% hydroperiod for MY5. With that said, the area of wetland represented by wetland gauges GW7, GW7-B, and GW7-C are still designated to “need more information.” Based on current information, RES thinks there is a likelihood that some of the wetland area represented by GW7 may ultimately be excluded from credit while the wetland areas represented by GW7-B and GW7-C may ultimately be included for credit. For the time being, these areas will not be considered in successful credit calculations; however, the wetland gauges will continue to be monitored in following monitoring years.  GW6 exceeded the success criteria, displaying a 14% hydroperiod in MY5. This area is considered in successful credit calculations as it has been successful for four consecutive years.  Field observations supports the presence of wetlands within portions Wetland H (WH). This wetland has been divided into three categories: 1) areas that are meeting wetland success and do not need supplemental data to prove success (2.652 acres), 2) areas that Meadow Spring 14 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 need more information and time in order to make a decisive call whether or not the area is passing wetland success criteria (2.115 acres), 3) areas that are at risk of not meeting performance criteria (2.069 acres). The areas that need more information and those at risk are not included in the calculations for successful credit areas during Year 5.  RES believes with continued normal rainfall amounts, portions of this area has potential to improve hydrology in the following years; however, not all portions of the originally proposed wetland are viable for successful crediting. Data supports the success of at least 10.153 credits at this time, more than the 7.200 WMU credits that have already been released, leaving 2.953 WMU viable credits available. Delineated areas and associated credit calculations can be found on Figure 3. Groundwater well locations can be found on Figure 2 and the associated data is in Appendix E. Meadow Spring 15 Year 5 Monitoring Report Stream and Wetland Mitigation Site October 2023 2 METHODS Stream monitoring was conducted using a Topcon GTS-312 Total Station. Three-dimensional coordinates associated with cross-section data were collected in the field (NAD83 State Plane feet FIPS 3200). Morphological data were collected at 24 cross-sections. Survey data were imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. The stage recorders include an automatic pressure transducer set in PVC piping in the channel. The elevation of the bed and top of bank at each stage recorder location was recorded to be able to document presence of water in the channel and out of bank events. Visual observations (i.e. wrack or debris lines) will also be used to document out of bank events. Vegetation success is being monitored at 18 permanent monitoring plots and three random 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 are 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. The random plots are to be collected in locations where there are no permanent vegetation plots. Random plots will most likely be collected in the form of 100 square meter belt transects with variable dimensions. Tree species and height will be recorded for each planted stem and the transects will be mapped and new locations will be monitored in subsequent years. Wetland hydrology is monitored to document success in wetland restoration and enhancement areas where hydrology was affected. This is accomplished with 11 automatic pressure transducer gauges (located in groundwater wells) that record daily groundwater levels. Ten have been installed within the wetland crediting area and one within reference wetland areas. One automatic pressure transducer is installed above ground for use as a barometric reference. Gauges are downloaded quarterly and wetland hydroperiods are calculated during the growing season. Gauge installation followed current regulatory guidance. Visual observations of primary and secondary wetland hydrology indicators are also recorded during quarterly site visits.
