At the 2016 IRT credit release, this project was released as proposed with the following notes: "Adjust as needed at the 2017 credit release. Explain in detail differences in stream footage from Mitigation Plan to As -Built. Were there changes to this easement?" Please provide response to these questions in the Monitoring report and be ready to discuss at credit release. Thalweg vs. centerline survey and construction field adjustments account for the 5% increase in stream footage from Mitigation Plan to As -Built. There were no changes to the easement. This has been added to the report. It is understood that morphology was not captured on this site for this monitoring year. This information below is for your understanding and preparation for credit release. Cross sections / cross section tables — A couple of methods are currently being utilized to calculate the BHR from year to year. To compare subsequent monitoring years to the As -built condition one can hold the bankfull depth static (denominator) while allowing the Low TOB max depth (numerator) to vary. Another method that has been proposed and is being evaluated is to hold the As -built cross-sectional area static within each years' new cross section and allow that to determine the max bankfull depth for each year. However, if there are large changes in the W/D ratio either method can make for somewhat distorted BHR values depending upon the direction and magnitude of the change in the W/D ratio. Please update calculations to reflect changes observed in the overlays and explain in detail as a table footnote how the calculations were made. Be prepared to defend the method used for credit release and justify through context if any changes observed in a cross section represent an issue. CCPV and asset table 1: a. Stream credit shapefile. The shapefile that DMS has for stream credit doesn't match the lengths shown in the report, although the total length is longer than reported in as -built (it's in the ballpark). Please provide the correct shapefile for the stream asset (divided by reach). This should match credit (within reason) and not include areas of road breaks. Done. res.us 0 b. Reach 6 credit: the map shows the upper portion of reach 6 as having Ell credit, but the Mitigation plan shows this as a non-credit area. I think you could list the upper portion of this reach and the side channel as additional stream, not for credit. Please update CCPV. The upper portion of Reach 6 (893 ft) and the side channel (307 ft) that confluences with it are now shown as "Channel — No Credit" on the CCPV and a footnote about them has been added to Table 1. Reach 6 is also is discussed in Section 1.3.1. Please provide a footnote with the number of trees replanted in 2016 under table 2 or under your vegetation table. 4,400 trees were replanted in 2016. This has been added as a footnote under Table 2. Page 7, please state what monitoring guidance was used for this project (i.e. 2003 IRT stream mitigation guidelines). The report is not specific. The monitoring guidance used was the EEP Monitoring Requirements and Performance Standards Guidance for Stream and -or Wetland Mitigation (11/07/2011). This has been added to the report. Page 11, Section 5.1.2: the 260 trees per acre standard is for MY5, please revise. Done. Table 10. Are these all the bankfull events or just 2017? It may be helpful to show number by monitoring year for context. I understand this is a shallow channel that regularly gets out of bank. These were all bankfull events for just 2017. The table has been updated to include bankfull events from each monitoring year. What is RES doing to address the minor encroachment noted on the report? Update to describe. In the areas of minor encroachment RES will communicate with landowners and install additional signage. This has been added to the report. Table 12. Some of the hydroperiods shown for this MY do not match their table below (Table 12A does not match table 12B for MY4). Correct and update. Done. As RES explained and we discussed in the field, there will need to be a strategy for repairing the isolated bank and floodplain scour on Reach 5A, including ensuring the encroachment is eliminated as soon as possible. RES plans to address the floodplain scour by seeding and matting the bare areas and hand grading and livestaking the head cuts. The bank scour will be remedied by adding rip rap behind the structure and livestakes to the bank. Additional t -posts with easement markers will be added to the encroachment area to deter any vehicle use through the easement. This has been added to the report. Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 Muddy Run II Duplin County, North Carolina DMS Project ID 95354 Cape Fear River Basin HUC 0030007060010 Prepared by: Resource Environmental Solutions, LLC 302 Jefferson Street, Suite 110 Raleigh, NC 27605 919-209-1061 Resource Environmental Solutions, LLC Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 EXECUTIVE SUMMARY The Muddy Run II Stream and Wetland Restoration Project is located within an agricultural watershed in Duplin County, North Carolina, approximately six miles south of Beulaville. The stream channels were heavily impacted by channelization and agricultural practices. The project involved the restoration and protection of streams in the Muddy Creek watershed. The purpose of this restoration project was to restore and enhance a stream/wetland complex located within the Cape Fear River Basin. The project lies within USGS Hydrologic Unit Code 03030007060010 (USGS, 1998) and within the North Carolina Division of Water Quality (NCDWQ) Cape Fear River Subbasin 03-06-22 (NCDENR, 2002). The project consists of six unnamed tributaries to Muddy Creek, but the project has been divided into nine distinct reaches for design purposes. Reach 1 is one of the upstream -most portions of the project; it begins on the edge of an existing agricultural field and extends to STA 04+48. Similarly, Reach 2 is one of the upper -most portions of the stream project. It begins in a disturbed forest corridor between several agricultural fields and extends to STA 19+14. Reach 3a starts at the confluence of Reaches 1 and 2 (STA 00+00) and flows north north-west through a disturbed hardwood buffer and several agricultural fields before being partially diverted to enter Reach 3b near STA 37+23. Reach 3b flows to the north and west where it flows into Reach 3c at STA 57+92. Reach 3c flows through a pine plantation to STA 65+30, where it flows into Reach 3 of the Muddy Run project. Reach 4 is a perennial channel that flows through a forested area from a ditch draining an agricultural field. Reach 4 flows into Reach 3A at STA 18+76. Reach 5a consists of the main stem beginning at STA 00+00 where it adjoins with Reach 1C of the Muddy Run project. Reach 5a flows north and flows into Reach 5b at STA 19+59. Reach 5b is the most downstream reach of the project, ending at the right-of-way for State Highway 41. Reach 6 begins in a forested area south of Reach 5 and flows in a northerly direction to the confluence with Reach 5a near STA 9+20. Two areas containing drained hydric soil were identified for restoration, located along Reach 3b and Reach 5a. The Muddy Run I Mitigation Project is located upstream of Reach 5A and downstream of Reach 3C. Muddy Run II was constructed immediately following Muddy Run. This Year 4 Annual Monitoring Report presents the data from 28 vegetation monitoring plots, four manual crest gauges, four auto crest gauges, an auto -logging rain gauge, seven wetland restoration groundwater gauges, three reference groundwater gauges, 59 stream cross sections, 20 sets of bank pins, and photo reference locations, as required by the approved Mitigation Plan for the site. The Year 4 vegetation monitoring observations for Muddy Run II Site are summarized in this report. Planted -stem survival for Monitoring Year 4 for all 28 Vegetation Plots (VP) at Muddy Run II was above the interim success criterion of 260 trees per acre at the end of Monitoring Year 4. The average stem density (excluding live stakes) across all vegetation plots was 638 stems per acre. Invasive Chinese privet (Ligustrum sinense) was observed along small portions of Reach 1B during Year 3 monitoring. Invasive treatment was performed in this area during July 2017. This area will continue to be monitored for invasive species. The Muddy Run II Site has met the Year 4 vegetation survival success criterion of 260 trees per acre as specified in the Mitigation Plan. During the Year 4 monitoring season, the restored stream channel remained stable and continued to provide the intended habitat and hydrologic functions. Monitoring Year 4 activities confirmed the stream reaches are stable and the banks are well vegetated. One stream area of concern was noted during the MY4 activities. Resource Environmental Solutions, LLC ii Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 All seven wetland gauges achieved the success criteria by remaining continuously within 12 inches of the soil surface for at least nine percent of the growing season. Groundwater gauge data indicates the hydroperiods being very responsive to rainfall events. Following 2016 monitoring the NCIRT requested a review of the differential between the Approved Mitigation Plan and Baseline Monitoring Report. The table below details the discrepancies by reach. The primary cause of the 5% increase in baseline SMUs is survey methodology (thalweg vs. centerline). The Mitigation Plan lengths were based on centerline. Wetland credits are unchanged from Mitigation Plan to Baseline Monitoring Report.

The project is in the Cape Fear River Basin (8 -digit USGS HUC 03030007, 14 -digit USGS HUC 03030007060010) (USGS, 1998) and the NCDWQ Cape Fear 03-06-22 sub -basin (NCDWQ, 2002). To access the Site from the town of Chinquapin, travel east on Highway 50, take the first left onto Pickett Bay Road (SR 1819), go 1.1 miles, then turn left onto Kenney Crawley Road. This private road is gravel and will split just past the residential house on the right. Keeping to the left will take you to the Reaches 3b, 3c, 5b, and 6. Going to the right at the split will take you to Reaches 1, 2, 3a, and 4. 1.2 Project Goals and Objectives The Muddy Run II stream and wetland mitigation project will provide numerous ecological and water quality benefits within the Cape Fear River Basin. While many of these benefits are limited to the project area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far-reaching effects. Expected improvements to water quality, hydrology, and habitat are outlined below. Design Goals and Objectives Benefits Related to Water Quality Benefit will be achieved through filtering of runoff from adjacent CAFOs through buffer areas, the Nutrient removal conversion of active farm fields to forested buffers, improved denitrification and nutrient uptake through buffer zones, and installation of BMPs at the headwaters of selected reaches and ditch outlets. Benefit will be achieved through the stabilization of eroding stream banks and reduction of sediment Sediment removal loss from field areas due to lack of vegetative cover. Channel velocities will also be decreased through a reduction in slope, therefore decreasing erosive forces. Increase dissolved oxygen Benefit will be achieved through the construction of instream structures to increase turbulence and concentration dissolved oxygen concentrations and riparian canopy restoration to lower water temperature to increase dissolved oxygen capacity. Runoff filtration Benefit will be achieved through the restoration of buffer areas that will receive and filter runoff, thereby reducing nutrients and sediment concentrations reaching water bodies downstream. Benefits to Flood Attenuation IF Water storage Benefit will be achieved through the restoration of buffer areas which will infiltrate more water during precipitation events than under current site conditions. Improved groundwater Benefit will be achieved through the increased storage of precipitation in buffer areas, ephemeral recharge depressions, and reconnection of existing floodplain. Greater storage of water will lead to improved infiltration and groundwater recharge. Improved/restored Benefit will be achieved by restoring the stream to a natural meandering pattern with an hydrologic connections appropriately sized channel, such that the channel's floodplain will be flooded more frequently at flows greater than the bankfull stage. Benefits Related to Ecological Processes Restoration of habitats Benefit will be achieved by restoring riparian buffer habitat to appropriate bottomland hardwood ecosystem. Benefit will be achieved through the construction of instream structures designed to improve Improved substrate and bedform diversity and to trap detritus. Stream will be designed with the appropriate channel instream cover dimension and will prevent aggradation and sedimentation within the channel. Substrate will become coarser as a result of the stabilization of stream banks and an overall decrease in the amount fine materials deposited in the stream. Resource Environmental Solutions, LLC Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 Addition of large woody Benefit will be achieved through the addition of wood structures as part of the restoration design. debris Such structures may include log vanes, root wads, and log weirs. Reduced temperature of water due to shading Benefit will be achieved through the restoration of canopy tree species to the stream buffer areas. Restoration of terrestrial habitat Benefit will be achieved through the restoration of riparian buffer bottomland hardwood habitats.

Muddv Run II Proiect Comuonents — Wetland Mitigation 1.3.1 Restoration Type and Approach Reach 1 Headwater valley restoration approach was performed along Reach 1. The existing channel/ditch was backfilled, and flow has been directed from its current position along the tree line back to within the historic valley location down to the confluence with Reaches 2 and 3a. A 100 foot wide forested buffer has been planted throughout the reach. The upstream limit of Reach 1 ties into an existing headwater valley system comprised of intermittent sections of single and multiple channels. This system will be used as a reference site for incorporating a small baseflow channel into the headwater valley restoration design. Reach 2 Similar to Reach 1, headwater valley restoration was performed along the upper section of Reach 2. The existing channel was backfilled with existing spoil material located along the channel, a result of Resource Environmental Solutions, LLC 3 Mitigation Mitigation Wetland Mitigation Type WMUs Area (ac) Ratio WA Restoration 3.60 1:1 3.60 WB Restoration 1.32 1:1 1.32 Total 4.92 4.92 1.3.1 Restoration Type and Approach Reach 1 Headwater valley restoration approach was performed along Reach 1. The existing channel/ditch was backfilled, and flow has been directed from its current position along the tree line back to within the historic valley location down to the confluence with Reaches 2 and 3a. A 100 foot wide forested buffer has been planted throughout the reach. The upstream limit of Reach 1 ties into an existing headwater valley system comprised of intermittent sections of single and multiple channels. This system will be used as a reference site for incorporating a small baseflow channel into the headwater valley restoration design. Reach 2 Similar to Reach 1, headwater valley restoration was performed along the upper section of Reach 2. The existing channel was backfilled with existing spoil material located along the channel, a result of Resource Environmental Solutions, LLC 3 Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 previous dredging activities. Areas within the 100 foot buffer that were disturbed or lack riparian vegetation were planted. Grade control structures were installed along three ditches that enter Reach 2 at the upstream end of the project. These structures raised the upstream channel bed elevations slightly to tie into existing ditches to the project reach. An existing CMP culvert located along the upstream section was removed and replaced outside the easement (upstream) to continue to allow the landowner access to all areas of his property. Priority I restoration was performed for the majority of Reach 2. Restoration activities involved relocating the channel to the north through an existing wooded area consisting primarily of pines and a few hardwoods. Existing spoil piles located along the channel banks were removed and used to fill the existing ditch. Diffuse flow structures have been installed along several ditches that outlet to the reach from both the north and south. The structures will attenuate and disperse flows as the existing ditches enter the proposed easement. Reach 3a Priority Level I restoration was performed on Reach 3a. The restoration approach on this reach included relocating the channel on either side of its current location to follow the natural valley and removing the adjacent roadbed to allow continuous access to the floodplain. Two existing 36" CMP culvert crossings were located along this reach. Each culvert was removed and replaced in-line with the proposed stream to allow the landowners to access portions of their respective properties to the west of the project site. Reach 3a now flows in a northwesterly direction until it reaches a property line. At this point, the existing ditch that continued to flow in a northerly direction was plugged and a diversion structure was installed. The structure is designed to pass 100 percent of baseflow and small storms through the project, and divert up to 70 percent of storms larger than the 25 -yr storm to the existing ditch and offsite. See Section 7.3.1.1 (Stream Hydrologic Analysis) for hydraulic analysis details. Just downstream of the diversion structure, the channel was relocated south of several turkey houses, and now flows in a westerly direction as Reach 3b. The network of ditches surrounding the turkey houses appear to cross a small ridge, directing flow away from the project area. An additional culvert crossing was constructed where flow will be diverted to the west at the turkey houses. Priority I restoration is appropriate for this channel because it is the only mitigation approach that addresses bed and bank instability, establishes a forested riparian buffer, and significantly enhances aquatic habitat. Diffuse flow structures were constructed where existing agricultural ditches enter the easement area. The diversion structure was constructed at the downstream end of Reach 3a to alleviate and prevent flooding caused by rerouting flow and increased drainage areas, to provide continued flow through the existing ditch for storms larger than bankfull (design) events, and to reduce impacts from proposed grading activities. Per discussions with Mr. Lanier (owner of parcel northwest of proposed structure), larger storm events overtop the existing ditch flowing to the north. This flooding may be attributed to inefficiencies with existing structures and ditch alignments in conjunction with low gradients. The culvert associated with the gravel access road that leads from Ludie Brown Road to the turkey houses outlets perpendicular to the receiving ditch that flows to the northeast and under Ludie Brown Road. This ditch continues to the northeast and crosses Route 111, where it flows to the north into Muddy Creek. By diverting up to 70 percent of higher flows through the existing ditch and offsite, existing flooding issues will be reduced adjacent to the turkey houses. This diversion also decreases potential flooding impacts that would occur if 100 percent of storm events were passed through the proposed channel, Reach 3b. There are several residential parcels within zero to 200 feet of the proposed easement along Reach 3b. Because the topography is very flat through this area, the flooding associated with the majority of storm events greater than bankfull would negatively impact these parcels. Finally, by diverting a percentage of the proposed higher flows, flooding impacts will also be reduced along Reaches 5a and 5b and at the existing HWY 41 culvert at the downstream end of the project. Currently, agricultural fields are present along the north side of Reach 5a. By reducing high flows, the Resource Environmental Solutions, LLC Muddy Run H Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 flooding extent and duration will be reduced; thus, preventing adverse impacts to crops. If 100 percent of higher storm events were allowed to pass through the project, significant grading would be required to cut floodplain terraces/benches to relieve flooding of the adjacent agricultural fields. Approximately 1,611 LF of the existing ditch that flows to the north from the Reach 3a/3b diversion structure will be impacted (dewatered). This length includes the segment of the ditch from the diversion structure downstream to the Muddy Creek floodplain. The channel impacts resulting from the proposed channel relocation will be addressed in the ensuing NWP application. Reach 3b Priority Level I restoration was performed on Reach 3b. The restoration approach on this reach included relocating the channel in a westerly direction through an open pasture. The pasture area has been extensively modified and substantial grading was required. The design then moves the channel to a historic drainage way as observed on LiDAR and historical aerial photographs. The flow path is now connected to a small relic channel identified in the forested area west of the pasture. Subsequent topographic survey confirmed positive drainage along the relic channel which follows a low lying feature observed on LiDAR. The restoration approach included some minor grading to enlarge the existing channel and to create a diverse bed habitat by constructing pools. Log grade control structures were installed at the confluence with Reach 3c and at the connection to the relic channel. Small, mechanical equipment and hand tools were used to minimize damage to the existing forested buffer. A livestock protected culvert crossing was constructed near the existing pasture along an existing farm path to allow the landowner uninterrupted access to his property. Reach 3c Enhancement I was performed on Reach 3c as it flows through a forested area downstream from Reach 3b to Reach 3 of the Muddy Run Stream Mitigation Project. A grade control structure was installed at the upstream end to stabilize the transition from an existing agricultural ditch to the stable channel. A crossing was constructed along the upper section to allow the landowner access to both sides of his property. Enhancement activities included removing portions of existing spoil piles located along top of banks, cutting floodplain benches and laying back banks, and installing woody debris habitat structures. Diffuse flow structures were also constructed at the downstream limit where existing agricultural ditches enter the easement area. Invasive species management was performed throughout the buffer, and any bare or disturbed areas were planted with native riparian vegetation. Reach 4 Priority 1 restoration was performed on the downstream end of Reach 4 as it flows through a forested area below a ditch draining an agricultural field. A grade control structure was installed at the upstream end to transition from the existing ditch to a stable channel. The lower section of the reach was constructed into an E -type channel before its confluence with Reach 3a. Invasive species management was performed throughout the buffer, and any bare or disturbed areas were planted with native riparian vegetation. Reach 5a Priority Level I restoration was performed on Reach 5a. The channel was relocated north of its current location into the adjacent agricultural field. The existing ditch was backfilled and plugged at any locations that may cross the proposed channel. The upstream end of the reach ties into Reach 1 C of the Muddy Run Stream Mitigation Project. The single -thread channel will flows through proposed wetland WB beginning approximately 300 feet downstream of the Muddy Run project. A CMP culvert crossing was installed in-line with the proposed design near the middle of the reach to allow the landowners access to the adjacent parcels. Priority I restoration is appropriate for this channel because it is the only Resource Environmental Solutions, LLC Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 mitigation approach that addresses bed and bank instability, establishes a forested riparian buffer, and significantly enhances aquatic habitat. Reach 5b Enhancement Level II was performed on Reach 5b. Several log grade controls and woody debris structures were installed along the bed to increase aquatic habitat and bed diversity. The right bank along the reach was laid back and spoil piles along the tops of banks were removed using small equipment to minimize impacts to the existing buffer. Additionally, invasive species management was performed throughout the buffer, and any bare or disturbed areas were planted with native riparian vegetation. Reach 6 Enhancement Level II was performed on the downstream section of Reach 6 (STA 9+02 to STA 12+19). The right and left banks were laid back, and the channel was backfilled using spoil located adjacent to the channel such that positive drainage is maintained throughout the reach down to the confluence with Reach 5a. Invasive species management was performed throughout the buffer where enhancement took place, and any bare or disturbed areas were planted with native riparian vegetation. A 50 foot wide buffer was provided along the upper section of Reach 6 (STA 0+00 to STA 9+02); however, no enhancement activities were performed through this section other than filling portions of the channel. This additional easement was provided to account for any hydrologic impacts that may occur as a result of the proposed enhancement activities. 1.4 Project History, Contacts and Attribute Data 1.4.1 Project History The Site was restored by Environmental Banc & Exchange, LLC (EBX) through a full -delivery contract awarded by NCDMS in 2011. EBX was acquired by Resource Environmental Solutions, LLC (RES) in 2014 and now oversees the project tasks. Tables 2, 3, and 4 in Appendix A provide a time sequence and information pertaining to the project activities, history, contacts, and baseline information. 1.4.2 Project Watersheds The easement totals 37.6 acres and is broken into nine reaches.

Resource Environmental Solutions, LLC Muddy Run H Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 2 Success Criteria The success criteria for the Site stream restoration was assembled from the EEP Monitoring Requirements and Performance Standards Guidance for Stream and -or Wetland Mitigation (11/07/2011). Specific success criteria components are presented below. 2.1 Stream Restoration 2.1.1 Bankfull Events Two bankfull flow events must be documented within the seven-year monitoring period. The two bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until two bankfull events have been documented in separate years. Bankfull events will be documented using crest gauges, auto -logging crest gauges, photographs, and visual assessments for evidence of debris rack lines. 2.1.2 Cross Sections 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 are 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. 2.1.3 Digital Image Stations Digital images are 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. 2.2 Wetland Restoration The NRCS does not have a current WETS table for Duplin County upon which to base a normal rainfall amount and average growing season. The closest comparable data was determined to be from Sampson County. The growing season for Sampson County is 242 days long, extending from March 17 to November 14, and is based on a daily minimum temperature greater than 28 degrees Fahrenheit occurring in five of ten years. Because of the surface roughing and shallow depressions, a range of hydroperiods are expected. The water balance indicates that the site will have a positive water balance in the early part of the growing season for four to five weeks, on average. The hydrology success criterion for the site is to restore the water table at the site so that it will remain continuously within 12 inches of the soil surface for at least nine percent of the growing season (approximately 22 days) at each groundwater gauge location during normal rainfall years. Overbank flooding events will provide additional inputs that may extend the hydroperiod in some years. Gauge data will be compared to reference wetland well data in growing seasons with less than normal rainfall. In periods of low rainfall, if a restoration gauge hydroperiod exceeds the reference gauge hydroperiod, and both exceed five percent of the growing season, then the gauge will be deemed Resource Environmental Solutions, LLC Muddy Run H Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 successful. If a gauge location fails to meet these success criteria in the seven year monitoring period, then monitoring may be extended, remedial actions may be undertaken, or the limits of wetland restoration will be determined. 2.3 Vegetation Specific and measurable success criteria for plant density within the riparian buffers on the site will follow NCDMS Guidance. Vegetation monitoring plots are 0.02 acres in size, and cover greater than two percent of the planted area. Vegetation monitoring will occur annually in the fall of each year. The interim measures of vegetative success for the site will be the survival of at least 320 three-year-old trees per acre at the end of Year 3, 260 trees per acre at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre at the end of Year 7. Invasive species on the site will be monitored and treated if necessary throughout the required vegetation monitoring period. 2.4 Scheduling/Reporting The monitoring program will be implemented to document system development and progress toward achieving the success criteria. The restored stream morphology will be assessed to determine the success of the mitigation. The monitoring program will be undertaken for seven years or until the final success criteria are achieved, whichever is longer. Monitoring reports will be prepared in the fall of each year of monitoring and submitted to NCDMS. The monitoring reports will include all information, and will be in the format required by NCDMS in Version 2.0 of the NCDMS Monitoring Report Template. 3 MONITORING PLAN Annual monitoring data will be reported using the DMS monitoring template. Annual monitoring shall be conducted for stream, wetland, and vegetation monitoring parameters as noted below. 3.1 Stream Restoration 3.1.1 As -Built Survey An as -built survey was conducted following construction to document channel size, condition, and location. The survey will include a complete profile of thalweg, water surface, bankfull, and top of bank to compare with future geomorphic data. Longitudinal profiles will not be required in annual monitoring reports unless requested by NCDMS or USACE. 3.1.2 Bankfull Events Four sets of manual and auto -logging crest gauges were installed on the site, one along Reach 2, one along Reach 3a, one along Reach 3b, and one along Reach 5a. The auto logging crest gauges were installed within the channel and will continuously record flow conditions at an hourly interval. Manual crest gauges were installed on the bank at bankfull elevation. Crest gauges will be checked during each site visit to determine if a bankfull event has occurred since the last site visit. Crest gauge readings and debris rack lines will be photographed to document evidence of bankfull events. 3.1.3 Cross Sections A total of 59 permanent cross sections were installed to monitor channel dimensions and stability. Four cross sections were installed along Reach 1 and ten cross sections were installed along Reach 2. There were 21 cross sections (nine runs, nine pools, and three riffles) installed along Reach 3A and six cross sections installed along Reach 313. Four cross sections were installed along Reach 3C and two cross Resource Environmental Solutions, LLC Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 sections were installed along Reach 4. Reach 5A had eight cross sections installed, while Reach 5B and 6 each had two cross sections installed. Cross sections were typically located at representative shallow and pool sections along each stream reach. Each cross section was permanently marked with 3/8 rebar pin to establish a monument location at each end. A marker pole was also installed at both ends of each cross section to allow ease locating during monitoring activities. Cross section surveys will be performed in monitoring years 1, 2, 3, 5, and 7 and will include all breaks in slope including top of bank, bottom of bank, streambed, edge of water, and thalweg. 3.1.4 Digital Image Stations Digital photographs will be taken at least once a year to visually document stream and vegetation conditions. This monitoring practice will continue for seven years following construction and planting. Permanent photo point locations at cross sections and vegetation plots have been established so that the same directional view and location may be repeated each monitoring year. Monitoring photographs will also be used to document any stream and vegetation problematic areas such as erosion, stream and bank instability, easement encroachment and vegetation damage. 3.1.5 Bank Pin Arrays Twenty bank pin arrays have been installed at cross sections located on meander pools. These bank pin arrays were installed along the upstream and downstream third of the meander. Bank pins are a minimum of three feet long, and have been installed just above the water surface and every two feet above the lowest pin. Bank pin exposure will be recorded at each monitoring event, and the exposed pin will be driven flush with the bank. 3.1.6 Visual Assessment Monitoring Visual monitoring of all mitigation areas will be conducted a minimum of twice per monitoring year by qualified individuals. The visual assessments will include vegetation density, vigor, invasive species, and easement encroachments. Visual assessments of stream stability will include a complete stream walk and structure inspection. Digital images will be taken at fixed representative locations to record each monitoring event as well as any noted problem areas or areas of concern. Results of visual monitoring will be presented in a plan view exhibit with a brief description of problem areas and digital images. Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal photos should indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral photos should not indicate excessive erosion or continuing degradation of the banks over time. A series of photos over time should indicate successional maturation of riparian vegetation. 3.1.7 Surface Flow Headwater valley restoration areas will be monitored to document intermittent or seasonal surface flow. This will be accomplished through direct observation, photo documentation of hydrology conditions, and dye tests if necessary. 3.2 Vegetation A total of 28 vegetation plots were randomly established within the planted stream riparian buffer easement. Each vegetation plot measures 22 feet by 40 feet (0.02 acres) and has all four corners marked with PVC posts. Planted woody vegetation was assessed within each plot to establish a baseline dataset. Within each vegetation plot, each planted stem was identified for species, "X" and "Y" origin located, and measured for height. Reference digital photographs were also captured to document baseline conditions. Species composition, density, growth patterns, damaged stems, and survival ratios will be Resource Environmental Solutions, LLC Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 measured and reported on an annual basis. Vegetation plot data will be reported for each plot as well as an overall site average. 3.3 Wetland Hydrology Wetland hydrology will be monitored to document hydric conditions in the wetland restoration areas. Seven automatic recording pressure transducer gauges were installed in representative locations across the restoration areas and an additional three gauges were installed in reference wetlands. The gauges will be downloaded quarterly and wetland hydroperiods will be calculated during the growing season. Gauge installation followed current regulatory and NCDMS guidance. Visual observations of primary and secondary wetland hydrology indicators will also be recorded during quarterly site visits. 4 MAINTENANCE AND CONTINGENCY PLAN All identified problematic areas or areas of concern such as stream bank erosion/instability, aggradation/degradation, lack of targeted vegetation, and invasive/exotic species which prevent the site from meeting performance success criteria will be evaluated on a case by case basis. These areas will be documented and remedial actions will be discussed amongst NCDMS staff to determine a plan of action. If it is determined remedial action is required, a plan will be provided. 4.1 Stream During the Year 4 monitoring activities, one stream problem area was documented. This area (SPA 1) is located on Reach 5A at station 19+50 and consists of right bank erosion caused by a dislodged structure from the toe of the bank. This area is mapped on the CCPV figure in Appendix B. Stream problem area 1 (SPA1) will be addressed by adding rip rap behind the dislodged structure and livestaking the bank to reduce further erosion. Stream problem areas identified during MY3 were inspected during MY4. Formerly SPA1, is now considered a vegetation problem area (see VPA2 below). The stream problem area is localized and the overall condition of the project streams on site are stable. Stream issues are described in Appendix B. 4.2 Vegetation Two vegetation problem areas were identified during monitoring Year 4 activities and is mapped on the CCPV figures. Vegetation problem area 1 (VPA1) is an area where encroachment from the adjacent farming operation occurred. This area is approximately a tenth of an acre in size and occurs on Reach 3A. RES will communicate with landowners and install additional signage in this area to prevent future issues. Vegetation problem area 2 (VPA2, formerly SPAT in MY3), is a bare slope with gully and rill erosion on Reach 5A. RES plans to reseed and mat this area as well as hand grade and livestake the associated headcuts. The two vegetation problem areas from MY4 are small and do not pose a threat to vegetation success criteria being met. All vegetation issues are described in Appendix B. 4.3 Wetlands No wetland problem areas were noted during the Year 4 monitoring period. During the 2017 growing season, all seven wells recorded water continuously within 12 inches of the soil surface for at least nine percent of the growing season. If any wetland problem areas are noted in the future, they will be documented and mapped on the Current Conditions Plan View (CCPV) as part of the annual stream and wetland monitoring report. Detailed wetland hydrology data is provided in Appendix D. Resource Environmental Solutions, LLC 10 Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 5 YEAR 4 MONITORING CONDITIONS (MY4) The Muddy Run II Year 4 Monitoring activities were completed in November 2017. All Year 4 monitoring data is present below and in the appendices. Data presented shows the site has one stream problem areas and two vegetation problem areas; however, the site is on track to meeting stream, wetland and vegetation interim success criteria. 5.1 Year 4 Monitoring Data Collection 5.1.1 Morphological State of the Channel Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. No indication of instability was observed during visual assessment and all structures are functioning as designed. Stream geomorphic data, including cross-sections, pebble counts, and bank pin arrays were not collected during Monitoring Year 4 activities per the monitoring guidance and schedule stated in the Mitigation Plan and As -Built Baseline Documents. This data will be collected in Monitoring Year 5 and documented in the MY5 report. 5.1.2 Vegetation The Year 4 monitoring (MY -4) vegetation survey was completed in November 2017 and resulted in an average of 638 planted stems per acre, well above the interim survival density of 260 stems per acre at the end of Year 5 monitoring. The average stems per vegetation plot was 13 planted stems. The minimum planted stems per plot was 8 stems and the maximum was 21 stems per plot. Sweetgum (Liquidambar styraciflua), Loblolly Pine (Pinus taeda), Winged Sumac (Rhus copallinum), Tulip Poplar (Liriodendron tulipifera), Serviceberry (Amelanchier arborea), and Red Maple (Acer rubrum) were noted volunteers during MY4 activities. Abundant herbaceous ground cover may have prevented the observance of these species in previous monitoring years. Vegetation summary data tables and plot photos can be found in Appendix C. 5.1.3 Photo Documentation Permanent photo point locations have been established at cross sections, vegetation plots, stream crossings, and stream structures by RES staff. Any additional problem areas or areas of concern will also be documented with a digital photograph during monitoring activities. Stream digital photographs can be found in Appendix B and Appendix C for vegetation photos. 5.1.4 Stream Hydrology Four sets of manual and auto -logging crest gauges were installed on the site, one along Reach 2, one along Reach 3a, one along Reach 3b, and one along Reach 5b. The auto logging crest gauges were installed within the channel and continuously record flow conditions at hourly intervals. Reaches 2, 3a, and 5b documented bankfull events during the Year 4 monitoring period. Crest gauge 1, which is located on Reach 2, documented five out of bank events during MY4 with a highest reading of 1.1 feet. Crest gauge 2 (Reach 3a) logged seven bankfull event during monitoring year 4 with a reading of 2.0 feet above bankfull elevation. Crest gauge 3 (Reach 3b) had no bankfull event readings during monitoring year 4. Crest gauge 4 (Reach 5b) documented eight bankfull events during MY4 with a highest reading of 2.8 feet. Crest gauge summary data and photo documentation of the bankfull events can be found in Appendix D. Resource Environmental Solutions, LLC 11 Muddy Run II Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • February 2018 5.1.5 Wetland Hydrology All seven wetland restoration gauges achieved the success criteria by remaining continuously within 12 inches of the soil surface for at least nine percent of the growing season. Groundwater gauge data indicate the hydroperiods being very responsive to rainfall events. Of the three reference wetlands gauges, only one (RAW2) did not meet success criteria, documenting 6 consecutive days (2%) throughout the growing season.

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. 2 = The acreage within the easement boundaries. 3 = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. 4 = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern/interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree/shrub stands over timeframes that are slightly longer (e.g. 1-2 decades). The low/moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygon/area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary. of Mapping CCPV Number of Combined Easement Vegetation Category Definitions Threshold Polygons Acreage Acreage ITDee¶iction 4.

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the project effort. 2 = The acreage within the easement boundaries. 3 = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. 4 = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern/interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree/shrub stands over timeframes that are slightly longer (e.g. 1-2 decades). The low/moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the "watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in red italics are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons. The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygon/area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary.
