Digital drawings: Ensure stream length attributes and wetland acre attributes in the respective shapefiles reflect assets/credits in Table 1 as required by contract and stated in DMS's Format, Data Requirements, and Content Guidance for Electronic Drawings Submitted to EEP version 1.0 (03/27/08). The design stream alignment shapefile and the Mitigation Plan wetland restoration shapefile is included in the Support Files. Table 5, UT4 shows an area of scour/erosion. Please provide GIS shapefile. Done. Tables 7 and 8 show stream problem areas and vegetation problem areas but there is no corresponding GIS shapefile. Please provide necessary shapefiles. The stream problem areas were repaired in December 2018. The GIS shapefile for the vegetation problem areas is included and labeled "Best_CCPV_Veg_Conditions_MY4". 2. Based on discussions from the 2016 IRT credit release, RES had the choice of submitting a credit modification request to the IRT to use credits based on As -Built or revert to approved mitigation plan credits. During the MY3 review, RES stated that they would not be submitting an asset revision request and would revert to the approved mitigation plan assets. Unfortunately, this was not done when the MY3 report was approved. Based on this, please revise all asset tables in Section 1.3, page 5 and Appendix A Table 1 to approved mitigation plan assets/credits. Done. 3. Section 1.3, page 5: Revise the first paragraph of this section to reflect that project assets/credits have now been reverted to approved mitigation plan assets/credits. What is in the report now is a regurgitation of what was written last year. Done. res.us 0 4. Section 5.1.5, page 17: The report states that "Rainfall data reported by CRONOS station Albert Ellis Airport (KOAJ) indicated rainfall was below average during the months of February, March, June, and September." Please verify data for September given that Hurricane Florence hit this area in mid- September 2018. The Albert Ellis Airport rain gauge malfunctioned during Hurricane Florence. More accurate rain data from the Williamsdale Field Lab was used to supplement the Albert Ellis Airport rain data. 5. Appendix A: Please submit Tables 1 through 4 as Excel files per the monitoring guidance. Done. 6. Appendix B, Table 5 (all): Provide description of red asterisk as footnote or remove if not necessary in both hardcopy and digital files. The red asterisk has been removed. 7. Appendix D: Make notation on appendix cover sheet and in Table of Contents that Stream Geomorphology Data/monitoring was not required for MY4. Done. 8. Appendix E: 2018 Groundwater Monitoring Gauge Hydrographs: In reviewing these hydrographs, it appears that the entire growing season was not observed for the wetland assessment/gauge data collection. Please explain why not. The wetland assessment/gauge data only represents 91 % of the growing season because the last monitoring site visit for 2018 was October 24. Despite missing data from the last 22 days of the growing season, all wetland gauges met the success criteria. Verify rainfall data for September. Looks low based on impacts from Hurricane Florence.

To access the downstream end of the site from the town of Beulaville, travel 0.6 miles east on NC HWY 24, take a right onto Lyman Road (SR 1801), and continue 1.6 miles southeast to the crossing with Muddy Creek. Reaches UT7, UT8, UT9, UT 10 and the lower end of Muddy Creek may all be accessed from Lyman Road. Reaches UT5 and UT6 are located just south of NC HWY 24, approximately 1.9 miles east of Beulaville. The upstream portion of the site may be accessed from two locations. Reaches UTI, UT2 and Muddy Creek are located to the south of NC HWY 24, opposite of the intersection of NC HWY 24 and Penny Road (SR 1720), approximately 2.8 miles east of Beulaville. To access reaches UT3, UT4 and Muddy Creek, travel 3.2 miles east on NC HWY 24 from Beulaville to Edwards Road (SR 1835), continue south for approximately 1.0 mile, turn right onto Put Lane, and follow the road down to Reaches UT3 and UT4. 1.2 Project Goals and Objectives The Best 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 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 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 appropriately hydrologic connections 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. Resource Environmental Solutions, LLC Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 Improved substrate and Benefit will be achieved through the construction of instream structures designed to improve bedform instream cover diversity and to trap detritus. Substrate will become coarser as a result of the stabilization of stream banks and an overall decrease in the amount of fine materials deposited in the stream. 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. The North Carolina Division of Mitigation Services (NCDMS) develops River Basin Restoration Priorities (RBRP) to guide its restoration activities within each of the state's 54 cataloging units. RBRPs delineate specific watersheds that exhibit both the need and opportunity for wetland, stream and riparian buffer restoration. These TLWs receive priority for DMS planning and restoration project funds. Currently, no Local Watershed Plan (LWT) is available for the project area. The 2009 Cape Fear River Basin River Basin Restoration Priorities (RPRP) identified HUC 03030007060010 as a Targeted Local Watershed (TLW). The watershed is characterized by 52 percent agricultural land use area with Muddy Creek identified as Impaired for aquatic life because of a Fair benthic community rating. The Best Stream and Wetland Restoration Project was identified as a stream and wetland opportunity to improve water quality, habitat, and hydrology within the TLW. The project goals address stressors identified in the TLW and include the following: • Nutrient removal, • Sediment removal, • Reducing runoff from animal operations, • Filtration of runoff, and • Improved aquatic and terrestrial habitat. The project goals will be addressed through the following project objectives: • Establishing riparian buffer areas adjacent to CAFOs, • Converting active farm field to forested buffers, • Stabilization of eroding stream banks, • Improving and protecting portions of headwater systems that discharge to a 303d listed stream, • Reduction in stream bank slope, • Restoration of riparian buffer bottomland hardwood habitats, and • Construction of in -stream structures designed to improve bedform diversity and trap detritus. The Best stream and wetland mitigation project is located within the northern (upstream) portion of the TLW and includes sections of Muddy Creek (303d listed) and headwater streams that discharge into Muddy Creek. Due to its location and improvements, the project provides 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. 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, addresses the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2009 Cape Fear RBRP. Resource Environmental Solutions, LLC Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 1.3 Project Structure Following 2016 monitoring the NCIRT requested a review of the differential between the Approved Mitigation Plan and Baseline Monitoring Report. RES does not plan on submitting an asset revision and will revert to the Approved Mitigation Plan assets.

Livestock was excluded with fencing installed along the easement boundary. An existing CMP culvert located along the middle of the reach was removed and replaced downstream at station 13+75 to allow the landowner access to both sides of the property. Stream Preservation and Buffer Enhancement was completed for the downstream section of the channel where it flows through a forested buffer down to the confluence with Muddy Creek. Buffer enhancement activities included the treatment of invasive exotic species by herbicide applications and/or mechanical control as well as planting bare root seedlings in sparsely vegetated areas. RES will continue to conduct invasive species treatments on an as needed basis. Additional treatments will be dependent on monitoring results and regulatory agency guidance. These treatments will be timed in accordance with specific invasive exotic plant phenology for the most effective control. Considering such factors as the influence of established invasive exotics on adjacent land, it is not feasible to expect complete eradication of the targeted invasive species. However, RES does expect to achieve significant reduction of targeted invasive exotic species through this control plan. The goal of the treatment program is control of invasive exotic species such that the target natural communities are present and on a positive trajectory at project closeout. UT2 Similar to UTI, Priority 1 restoration was completed for UT2 to address historic straightening and channel enlargement. The existing channel was backfilled, and the restored channel was relocated such that it meanders within the existing valley. A diffuse flow structure was installed at the ditch adjacent to the proposed crossing. The structure was placed such that flows from the existing ditch will be attenuated to establish sheet flow as the water enters the restored channel. All areas within the minimum 50 foot buffer were planted with native riparian vegetation. An existing 60" CMP culvert located at station 20+25 of the reach was removed and replaced with a 48" HDPE culvert to allow the landowner access to the entire property. Additionally, the existing culvert at the upstream end of UT2 was upgraded to a 48" HDPE culvert and reset to more effectively transition the existing channel upstream into the project stream. Priority Level I restoration was appropriate for this channel because it was the only mitigation approach that would address bed and bank instability, establish a forested riparian buffer, and significantly enhance aquatic habitat. Stream Preservation and Buffer Enhancement was completed for the most downstream section, where the channel enters the existing forested buffer, down to its confluence with Muddy Creek. Buffer enhancement activities included the treatment of invasive exotic species by herbicide applications and/or mechanical control as well as planting bare root seedlings in sparsely vegetated areas. RES will continue to conduct invasive species treatments on an as needed basis. Additional treatments will be dependent on monitoring results and regulatory agency guidance.

However, RES does expect to achieve significant reduction of targeted invasive exotic species through this control plan. The goal of the treatment program is control of invasive exotic species such that the target natural communities are present and on a positive trajectory at project closeout. UT3 Enhancement Level II was completed on Reach UT3 due to the channel's stability and appropriate size. The design approach on this reach focused on improving the riparian buffer. The existing hog lagoon located within buffer on the west side of the reach has remained in place, preventing the generation of stream credits for approximately 600 linear feet. Through this section, the left buffer was extended out to a minimum of 75 feet along the left bank, and the right buffer was extended just past top of bank. The existing crossing located at station 8+50 was replaced and upgraded with a 30" HDPE pipe, allowing the landowner continued access across his property. Additional bank grading Resource Environmental Solutions, LLC Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 and stabilization was included in the culvert replacement. The grading of pools and the installation of woody debris structures was performed along the reach to improve aquatic habitat. Upstream of the crossing, a 75 -foot buffer was restored along the east bank where the channel currently flowed through an active pasture. A 100 -foot buffer was implemented for the headwater origin point to further protect water quality from cattle access. Cattle have been excluded with fencing. All areas within the buffer were planted with native riparian vegetation. Stream Preservation and Buffer Enhancement was implemented along the downstream end where the channel enters the Muddy Creek floodplain. Buffer enhancement activities included the treatment of invasive exotic species by herbicide applications and/or mechanical control as well as planting bare root seedlings in sparsely vegetated areas. RES will continue to conduct invasive species treatments on an as needed basis. Additional treatments will be dependent on monitoring results and regulatory agency guidance. These treatments will be timed in accordance with specific invasive exotic plant phenology for the most effective control. Considering such factors as the influence of established invasive exotics on adjacent land, it is not feasible to expect complete eradication of the targeted invasive species. However, RES does expect to achieve significant reduction of targeted invasive exotic species through this control plan. The goal of the treatment program is control of invasive exotic species such that the target natural communities are present and on a positive trajectory at project closeout. UT4 Headwater valley restoration was completed for the upper section of UT4. The existing channel was backfilled, and flow was directed from its current position east back to the historic valley location. A minor amount of earthwork was completed in the headwater valley restoration apart from ditch plugging to tie the existing ditch back to the natural valley. Areas within the 100 foot buffer that were disturbed or lacked riparian vegetation were planted. Cattle were excluded from the buffer through the installation of fencing. An existing 15" CPP culvert crossing located at station 8+50 of the reach was removed and replaced with triple 18" HDPE culverts. This crossing was relocated to the low spot in the valley to allow the landowner continued access to an agricultural field west of the channel. Downstream of the crossing, a smaller low flow channel was constructed within the natural valley. This segment now connects the upstream headwater valley section to the existing channel approximately 230 feet below the crossing. Due to the stable nature of the buffer along the downstream reach of UT4, Stream Preservation and Buffer Enhancement was implemented from just downstream of the crossing to the confluence with Muddy Creek. Buffer enhancement activities included the treatment of invasive exotic species by herbicide applications and/or mechanical control as well as planting bare root seedlings in sparsely vegetated areas. RES will continue to conduct invasive species treatments on an as needed basis. Additional treatments will be dependent on monitoring results and regulatory agency guidance.

However, RES does expect to achieve significant reduction of targeted invasive exotic species through this control plan. The goal of the treatment program is control of invasive exotic species such that the target natural communities are present and on a positive trajectory at project closeout. UT5 Stream Preservation and Buffer Enhancement was completed on UT5. The channel is stable throughout the easement and provides a variety of aquatic habitats. The easement boundary extends a minimum of 50 feet outward from the stream channel, or the limit of adjacent riparian wetlands, whichever is wider. The riparian buffer is an intact hardwood forest with localized areas of privet. Buffer enhancement activities included the treatment of invasive exotic species by herbicide applications and/or mechanical control as well as planting bare root seedlings in sparsely vegetated areas. RES will continue to conduct invasive species treatments on an as needed basis. Additional Resource Environmental Solutions, LLC Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 treatments will be dependent on monitoring results and regulatory agency guidance. These treatments will be timed in accordance with specific invasive exotic plant phenology for the most effective control. Considering such factors as the influence of established invasive exotics on adjacent land, it is not feasible to expect complete eradication of the targeted invasive species. However, RES does expect to achieve significant reduction of targeted invasive exotic species through this control plan. The goal of the treatment program is control of invasive exotic species such that the target natural communities are present and on a positive trajectory at project closeout. UT6 Enhancement Level I was completed on UT6. The mitigation approach on this reach focused on bank stabilization, bedform diversity, and improving the riparian buffer. The existing channel was impaired by channelization, vertical un -vegetated banks, and a dense privet understory within the buffer. The grading of pools, grade control structures, and the installation of woody debris structures were implemented along the reach to improve aquatic habitat. All disturbed areas within the riparian buffer were planted with native riparian vegetation. UT7 Stream Preservation and Buffer Enhancement was completed on UT7. The channel is stable throughout the easement and provides a variety of aquatic habitats. The easement boundary extends a minimum of 50 feet outward from the stream channel, or the limit of adjacent riparian wetlands, whichever is wider.

Wetland W1 Wetland W 1 is located at the headwater of UT 1 and has a natural constriction at the outlet. The soil is a sandy loam/loamy sandy underlain by clayey textured subsoil that forms an effective restrictive Resource Environmental Solutions, LLC Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 layer to groundwater loss. This area receives runoff from NC HWY 24. Based upon soil and landscape position, it is likely this area has a seasonal seepage along the upper boundary. Site modifications included removal of dredged and excavated materials, plugging the ditch, and raising the streambed elevation to bring the water table closer to the ground surface. Additional temporal habitat was constructed to eliminate surface leveling and smoothing for agricultural use. The temporal habitat is variable to mimic sloughs, oxbows, root -tips and other shallow natural features. During monitoring, beaver activity will be controlled to allow the site to stabilize and vegetative community to establish. After the monitoring period, the site is designed to promote and tolerate beaver activity. No hydrologic trespass is anticipated due to beaver activity in this wetland. These modifications will increase storage and eliminate the rapid loss of surface water. This area may receive limited overbank flows due to location in the headwater of UT 1. Subsoil ripping and roughing of the soil surface were performed to ameliorate soil compaction and create an uneven surface more conducive for surface water retention, infiltration, and increase storage that would be present in natural wetland systems. Wetland W2 Wetland W2 is located at the toe slope along Muddy Creek and UT2. The soil is a sandy loam/loamy sandy underlain by sandy clay loam and sandy clay. This site is at a low elevation and is influenced by the water table on the floodplain of Muddy Creek. It is unlikely that groundwater loss is significant during most of the year. This area has a small watershed, but flooding from UT2 and Muddy Creek will increase hydrologic storage. Hydrology was restored by removing dredge material along the channel and raising the streambed elevation, bringing the water table closer to the ground surface. Site modifications included subsoil ripping, crown removal, and surface roughing of the area. Additional temporal habitat was constructed to eliminate the surface leveling and smoothing for agricultural use. The temporal habitat is variable to mimic sloughs, root -tips and other shallow natural features. This ameliorates past soil leveling and compaction and creates an uneven surface more conducive of infiltration and storage that would be present in natural wetland systems. Wetland W3 Wetland W3 is composed of two similar area (W3a and W3b) located at the toe slope along Muddy Creek. A low finger of soil separates them. The soil in these areas is a loamy sand/sandy loam. The surrounding upland is underlain by clayey subsoil that forms an effective restrictive layer that lateral flow rides provide additional hydrological input. A ditch is located upslope of these areas and alongside W3a that drains to Muddy Creek. The soil is a sandy loam/loamy sand. The surrounding upland has a sandy clay loam and sandy clay that form an effective restrictive layer that lateral flow rides provide additional hydrological input. Both areas have small watersheds, but W3b receives groundwater seepage along the toe of slope diverted by the upslope ditch. Hydrology was restored by filling ditches and enhancing the concave topography by removing soil material where cultivation had filled low features and leveled the surface to facilitate cultivation. Additional groundwater seepage diverted by the ditch was restored to these wetlands. Temporal habitat was constructed to eliminate the surface leveling and smoothing for agricultural use. Subsoil ripping and surface roughing of the area was performed to ameliorate soil compaction and create an uneven surface more conducive of infiltration and storage that would be present in natural wetland systems.

Muddy Creek is a stable swamp stream system with intact hardwood forest floodplain, extending from approximately 0.3 miles west of Edwards Road to 0.5 miles south of Lyman Road. Muddy Creek has a drainage area of 4.6 square miles (2,930 acres) at the downstream limits and has an existing length of 9,214 linear feet. 2 Success Criteria The success criteria for the Best Site will follow accepted and approved success criteria presented in the USACE Stream Mitigation Guidelines and subsequent NCDMS and agency guidance. 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 Resource Environmental Solutions, LLC 11 Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 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). Starting in MY3, BHR was calculated on riffles using the baseline bankfull elevation. This method was used because the dimension of the channels has not changed enough to alter the bankfull elevation. None of the restoration riffle cross sections exceeded a 1.2 BHR. Two cross sections on Enhancement I reaches did exceed 1.2 but both have baseline bankfull elevations below top of bank. 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 Bank Pin Arrays Bank pin arrays will be used as a supplemental method to monitor erosion on selected meander bends where there is not a cross section. Bank pin arrays will be installed along the outer bend of the meander. Bank pins will be 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, 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. 2.1.4 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 Success criteria and monitoring for wetland hydrology within the wetland restoration areas on the site follows NCDMS Guidance dated 7 November 2011. The target minimum wetland hydroperiod is 9 percent of the growing season. Stream hydrology and water balance calculations indicate the wetland area will meet jurisdictional criteria (5 percent hydroperiod). However, due to immature vegetation and reduced PET, a longer success criterion is appropriate. Auto recording gauges are used to measure daily groundwater elevations throughout the Sampson County growing season in all 7 years of monitoring. If a hydrology 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 groundwater modeling may be used to demonstrate the limits of wetland restoration. Resource Environmental Solutions, LLC 12 Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 2.3 Vegetation Success Criteria Specific and measurable success criteria for plant density within the wetland restoration and riparian buffers on the site will follow NCDMS Guidance dated 7 November 2011. Vegetation monitoring plots are a minimum of 0.02 acres in size, and cover a minimum of two percent of the planted area. The following data is recorded for all trees in the plots: species, height, planting date (or volunteer), and grid location. Monitoring occurs in the fall of Years 1, 2, 3, 5, and 7. The interim measures of vegetative success for the site is the survival of at least 320 three-year old planted trees per acre at the end of Year 3, and 260 planted trees per acre at the end of Year 5. The final vegetative success criteria is the survival of 210 planted trees per acre at the end of Year 7 of the monitoring period. Invasive and noxious species will be monitored and controlled so that none become dominant or alter the desired community structure of the site. If necessary, RES will develop a species-specific control plan. 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 is 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 be in the format required by NCDMS in Version 2.0 of the NCDMS Monitoring Report Template (Oct. 2010). 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 includes 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 Six sets of manual and auto -logging crest gauges were installed on the site, one along UTI, UT2, UT3, UT4, UT6, and one along UT8. 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. Flow days will be reported on headwater valley restoration reaches. Resource Environmental Solutions, LLC 13 Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 3.1.3 Cross Sections A total of 31 permanent cross sections were installed to monitor channel dimensions and stability. Twelve cross sections were installed along UTI where Priority 1 restoration was performed. Twelve cross sections (six pools and six shallows) were installed along UT2 also. UT4 has a total of two cross sections installed throughout its length. Stream segment UT6 has two cross sections installed along its length where enhancement activities were performed. On the UT8 side of the project, a total of three cross sections were installed. Cross sections were typically located at representative riffle 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 once a year during annual 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 Eight bank pin array sets have been installed at pool cross sections located along UTI and UT2. 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 is conducted a minimum of twice per monitoring year by qualified individuals. The visual assessments include vegetation density, vigor, invasive species, and easement encroachments. Visual assessments of stream stability include a complete stream walk and structure inspection. Digital images are 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 are 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 The headwater valley restoration area on UT4 will be monitored to document intermittent or seasonal surface flow. This will be accomplished through direct observation, photo documentation of dye tests, and continuous flow monitoring devices (pressure transducers). An auto logging crest gauge has been installed within the headwater valley channel and will continuously record flow conditions at an hourly interval. This gauge will be downloaded during each site visit to determine if intermittent or seasonal flows conditions are present. Resource Environmental Solutions, LLC 14 Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 3.2 Wetland Hydrology Wetland hydrology will be monitored to document hydric conditions in the wetland restoration areas. This will be accomplished with automatic recording pressure transducer gauges installed in representative locations across the restoration areas and reference wetland areas. A total of twelve automatic recording pressure transducers (Auto -Wells) have been installed on the site. Nine auto - wells have been installed within the wetland restoration area and three within reference areas. The gauges will be downloaded quarterly and wetland hydroperiods will be calculated during the growing season. Gauge installation followed current regulatory and DMS guidance. Visual observations of primary and secondary wetland hydrology indicators will also be recorded during quarterly site visits. 3.3 Vegetation A total of 23 vegetation plots were randomly established within the planted stream riparian buffer easement. Vegetation plots measure 10 meters by 10 meters or 5 meters by 20 meters (0.02 acres) and have all four corners marked with metal 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 measured and reported on an annual basis. Vegetation plot data will be reported for each plot as well as an overall site average. 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 Three stream problems were identified during the Year 4 monitoring period and have been mapped on the Current Conditions Plan View (CCPV) (Figure 3). The fence problem area reported in MY3 was repaired in January 2018. Stream problem area 1 (SPA1) consists of minor bank erosion on UT4 at station 10+20. This area appears stable and RES plans to continue to monitor these areas to see if they worsen. If conditions continue to worsen, livestakes and additional bank matting will be installed along the banks. Stream problem area 2 (SPA2) is located on UT4 from station 8+47 to 8+67. This area consists of ponding on the road, due to downstream issue at SPA3. The area involves adding fill material to eliminate the ponding on the road. SPA3 is located on UT4 from station 8+75 to 11+03 and is attributed to the subsidence of the plug that had been installed at construction. This problem is associated with the relic stream channel. Fill material needs to be added to raise the plug elevation in the relic channel. All stream problem areas are localized and the overall condition of the project streams on site are stable. Remedial action repair work was completed in December 2018. 4.2 Wetlands No wetland problems areas were noted during the Year 4 monitoring period. Wetland hydrology and vegetation represent typical conditions of a site in Year 4 post construction monitoring. If any wetland problem areas are identified in the future, they will be documented and mapped on the CCPV (Figure 3) as part of the annual monitoring report. The Best Site wetland restoration areas are performing as designed and are on track to meeting wetland success criteria. Resource Environmental Solutions, LLC 15 Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 4.3 Vegetation Two vegetation problems were identified during the Year 4 monitoring period. These vegetation problem areas are documented and mapped on the CCPV (Figure 3) as part of the annual monitoring report. The poor growth and low stem density areas reported in MY3 along UTI and UT3 were replanted in January 2018. Vegetation problem area 1 (VPA1) is an area where the invasive species mimosa (Albizia julibrissin) and Chinese privet (Ligustrum sinense) are present along UTI and Wetland 1. This area is approximately a tenth of an acre in size, and is well vegetated with native trees and native herbaceous cover. RES plans to continue treat the invasive species in this area. Vegetation problem area 2 (VPA2) is a low stem density area at the top of UT8. This area was replanted in December 2018. 5 YEAR 4 MONITORING CONDITIONS (MY4) The Best Site Year 4 Monitoring activities were completed October 2018. All Year 4 monitoring data is present below and in the appendices. Morphological stream data was not collected in MY4 per the Approved Mitigation Plan. 5.1 Year 4 Monitoring Data Collection 5.1.1 Morphological State of the Channel Morphological stream data was not collected in MY4 per the Approved Mitigation Plan. It will be collected and reported again in MY5 and MY7. 5.1.2 Vegetation The Year 4 monitoring (MY4) vegetation survey was completed in October 2018 and resulted in an average of 753 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 19 planted stems. The minimum planted stem per acre was 243 and the maximum was 1,255. Vegetation Plot 2 fell one tree below the interim success criteria. This area is dominated by blackberry bushes and was replanted in January 2018 but not all the replanted stems in the plot survived. Volunteers were noted in a few vegetation plots on the site and were recorded within the CVS-EEP Data entry tool. The average planted stem height was 7 feet. Vegetation summary data tables can be found in Tables 9a -c and vegetation plot photos in Figure 4. 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 Figure 5 and 7 and Figures 4 and 6 for vegetation photos. 5.1.4 Stream Hydrology Six sets of manual and auto -logging crest gauges were installed on the site, one along UT1, UT2, UT3, UT4, UT6, and one along UT8. The auto logging crest gauges were installed within the channel and will continuously record flow conditions at an hourly interval. Five of five crest gauges recorded bankfull events during the Year 4 monitoring period (Table 13; Figure 8). All crest gauges with a bankfull standard have met the success criteria. Crest Gauge 4 is located on a headwater valley restoration reach and it's success criteria is 30 days of continuous flow. This year's correction factor Resource Environmental Solutions, LLC 16 Best Stream and Wetland Restoration • USGS HUC 03030007 Year 4 Monitoring Report • Duplin County, North Carolina • January 2019 was used to calculate the flow days in the monitoring years it was not reported. MY1 recorded 190 days of consecutive flow, MY2 had 288 days of consecutive flow, MY3 had 200 days of consecutive flow and MY4 recorded 282 consecutive days of flow. 5.1.5 Wetland Hydrology A total of twelve wetland hydrology gauges are installed at the Best Site, nine in areas of wetland restoration and three as reference gauges in existing on-site wetland. Nine of the nine wetland restoration gauges achieved the success criteria by remaining continuously within the 12 inches of the soil surface for at least nine percent of the growing season. Groundwater gauge data indicate the hydroperiods being responsive to rainfall events. Rainfall data reported by CRONOS station Williamsdale Field Lab indicated rainfall was below average during the months of February, March, August, and October. All three reference gauges met the nine percent success criteria with. Wetland gauge and rainfall data is presented in Appendix E. 6 REFERENCES Chow, Ven Te. 1959.

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 Depiction Polygons Acreage Acreage 4.

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.
