In Year 1, 16 of the 18 fixed vegetation plots met the 320 stems per acre success criteria. The three random vegetation plots also met the 320 stems per acre success criteria. Bankfull events were recorded on the stage recorder on S11. Due to the groundwater wells missing the first three months of the growing season, only two of the 11 met the 12 percent hydroperiod success criteria. The one vegetation problem area onsite is the 0.75-acre low stem density area in and around Vegetation Plot 9 and 16, which will be replanted in early 2020. Three stream problem areas were also reported in Year 1. The first was a series of bank erosion on S2 and S6A which will be repaired in early 2020 with the installation of brush mattresses. The second was a rill that formed off of a filled ditch that will be repaired in early 2020 with wattles and Iivestakes. And the third was an eroded point bar on S6A that will be regraded, matted, and Iivestaked in early 2020. RES is requesting a 10% stream credit release (544.00 SMUs) and a 10% wetland credit release (1.44 WMUs) for the completion of the Year 1 monitoring report. Please see enclosed the credit release timeline and an updated credit ledger.

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 lies within USGS Hydrologic Unit Code (HUC) 03020201100050. The 2010 Neuse River Basin Plan (RBRP) identified the Neuse River watershed (HUC 03020201100050) as a Targeted Local Watershed (TLW), a watershed that exhibits both the need and opportunity for wetland, stream, and riparian buffer restoration. 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 Priority I/II restoration, Enhancement Levels III 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 occur adjacent to Priority I stream 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 includes 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 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. Meadow Spring 2 Year 1 Monitoring Report Stream and Wetland Mitigation Site January 2020 1.2 Project Goals and Objectives The 2010 Neuse River Basin Restoration Priorities (RBRP) identified several restoration needs for the entire Neuse River Basin, as well as for HUC 03020201, specifically. The Site is in HUC 03020201100050 (Meuse 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. • 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. Meadow Spring 3 Year 1 Monitoring Report Stream and Wetland Mitigation Site January 2020 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. Wetland Success Criteria The Natural Resources Conservation Service (MRCS) 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 each groundwater gauge location. Based on the extensive management history of the Site and soil compaction, RES expects a slighty reduced hydroperiod in the monitoring years 1 and 2. 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. Meadow Spring 4 Year 1 Monitoring Report Stream and Wetland Mitigation Site January 2020 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 S613. The southern portion of the project includes Reaches S7, S9, S11, S12 and S13. The stream and wetland mitigation components are summarized below.

S Design/Approach Stream The Meadow Spring Site includes Priority I/Priority II Restoration, Enhancement Level I, Enhancement Level II, Enhancement Level IIL 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.

Preservation included invasive treatment and buffer/stream protection. 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. Meadow Spring 7 Year 1 Monitoring Report Stream and Wetland Mitigation Site January 2020 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. 1.7 Year I Monitoring Performance (MY]) The Meadow Spring Year 1 Monitoring activities were performed in December 2019. All MY1 data is present below and in the appendices. The Site is on track to meeting vegetation, stream, and wetland interim success criteria. Vegetation _ Monitoring of the 18 permanent vegetation plots and three random vegetation plots was completed during December 2019. Vegetation data are in Appendix C, associated photos are in Appendix B, and plot locations are in Appendix B. MY1 monitoring data indicates that 16 of the 18 plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 121 to 1,052 planted stems per acre with a mean of 571 planted stems per acre across the permanent plots. Vegetation Plot 9 and 16 did not meet the success criteria with 121 and 283 stems per acre respectively. A total of 18 species were documented within the plots. Volunteer stems were noted in one plot. The average planted stem height in the permanent plots was 1.8 feet. Data from the three random vegetation plots showed 769 stems/acre in Random Plot 1, 688 stems/acre in Random Plot 2, and 324 stems/acre in Random Plot 3. The average height in the random vegetation plots was 2.0 feet. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. The areas in and around VP9 and VP 16 (0.75 acres) will be replanted in early 2020. These areas are shown as VPA1 and VPA2 in Appendix B. RES also plans to supplemental plant a few other areas onsite where plots still met success but only marginally. Stream Geomorphology Geomorphology data for MY was collected during December 2019. Summary tables and cross section plots are in Appendix D. Overall, the MY1 cross sections relatively match the as -built conditions. Minor adjustments are expected during the first few years after construction. Cross Sections 2, 4, 7, and 18 experienced about one foot of change in dimension in MYL These areas will remain under close watch during the subsequent monitoring years. Bank height ratios remain less than 1.2 and entrenchment ratios greater than 2.2 on restoration reaches. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation. Three stream problem areas were noted in MY1. The first, SPA1, is a series of eroded banks on S2 and S6A. One of eroded bank areas can be seen on Cross Section 4. These banks will be hand graded back, repaired with brush mattresses, and the livestakes will be replanted. The second, SPA2, is a rill that formed off of the plugged ditch in WL This area will be repaired by installing a few wattles and planting of livestakes, to slow down the flow and acclimate sediment. The last, SPA3, is an eroded point bar that was caused by heavy flows from the pond outfall channel that confluences with S6A on the opposite bank. RES will grade the eroded point bar to a 3:1 slope Meadow Spring 8 Year 1 Monitoring Report Stream and Wetland Mitigation Site January 2020 and add matting and livestakes to protect it from future heavy flows. These areas are shown on Figure 2 and in Appendix B. Stream Hydrology Two stage recorders were installed in June 2019 to document bankfull events. One stage recorder on Reach S613 and one stage recorder on Reach 511. The stage recorder on Reach S613 recorded zero bankfull events in MY1. The stage recorder on Reach S11 recorded two bankfull events with the highest being 0.77 feet above top of bank. Recorder locations can be found on Figure 2 and associated data is in Appendix E. Wetland Hydrology Eleven groundwater wells were installed in June 2019, including one reference well, to monitoring wetland hydrology. MY1 data showed 2 of the 11 groundwater wells met the 12 percent hydroperiod success criteria. Hydroperiods ranged from 2 to 19 percent with the reference well documenting a 2 percent hydroperiod. MY1 groundwater data represented July through the end of the growing season for all wells with the exception of GW11 which was installed in August. RES expects the hydroperiods to increase when the early growing season data is included in subsequent years. Groundwater well locations can be found on Figure 2 and the data will be included subsequent monitoring reports. 2.0 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.
