Digital drawings: Show the 7% and 8% hydroperiods in the attribute table for the Wetland Success shapefile instead of the ranges currently shown. Done. 2. Section 1.3: a. 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. b. Table 1 a: (1) Change "Proposed SMUs/WMUs" to "Approved Mitigation Plan SMUs/WMU" (2) Change "Baseline SMUs/WMUs" to "As -Built Baseline SMUs/WMU" (3) Add footnote for Proposed (stream) Length and the two columns commented on above that measurements are based on centerline. Done. 3. Section 5.1.4: Please state whether this site has met the bankfull standard. If it has, please show the cumulative years of bankfull events in Table 13 in Appendix E. The site has met the bankfull standard with bankfull events happening in two separate years (MY2 and MY4). This has been added to Section 5.1.4. 4. Section 5.1.5: a. Note that AW 7 has never met hydrologic success of 9% in years 1 through 4. If hydrology doesn't at least show improvement in MY5, this area may need to be removed from credit. The ditch that RES inferred was draining this wetland area was plugged in October 2018. RS expects this gauge to trend towards and meet success criteria over the remaining three years of monitoring. b. Note that AW 11 has missed hydrologic success of 9% in 3 of 4 years. RES may need to begin looking at refining assets in this area as well. AW 11 is located on the outer edge of the Johns fine sandy loam area. According to Wetland Saturation Threshold Table in the 2016 Mitigation Update, Thermic Aquic Hapludults wetland res. us 0 saturation range is 6-8%. This means AW 11 would have met two of the four years with the two successful years being the most recent showing an upward trend. 5. Appendix A, Table 1: Update footnote to read something like "Credit calculations were originally calculated along the as -built thalweg. For Monitoring Year 3 forward, credits were updated to be calculated along stream centerlines for after discussions with NC IRT stemming from the April 3, 2017 Credit Release Meeting." Done. 6. Appendix B: a. CCPV: The locations of bank pins are not shown. Please show on appropriate figure(s). Done. b. Table 5 (all): Provide description of red asterisk as footnote or remove if not necessary in both hardcopy and digital files. The asterisks have been removed. c. Table 6: Explain why there is nothing discussed on the Invasive Area of Concern row when you discuss invasive vegetation in the report narrative, show it on the CCPV and list it in Table 7. The invasive species area has been quantified on Table 6, displayed on the CCPV, and listed in Table 7. 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: a. 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. RES collected additional groundwater monitoring on January 10, 2019. The report now includes data from the entire growing season. b. Verify rainfall data for September. Looks low based on area impacted by Hurricane Florence. The rainfall data recorded 25 inches for September. The average September rainfall near Clinton, NC is 5 inches. 9.

To access the Site from the town of Clinton, travel west on Highway 24 (Sunset Avenue), take a left onto Airport Road and go 1.3 miles. Turn right onto West Main Street Extension, go approximately 350 feet, and turn left onto a dirt farm path. Follow the farm path along the cultivated field edge to the southwest corner and enter the forest. Follow the dirt path to cultivated fields adjacent to the project below UT2. Turning to the left will take you to UT2. Going to the right will take you to UT3. 1.2 Project Goals and Objectives The Cedar Creek Stream and Wetland Restoration Project has provided 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 agricultural fields through buffer Nutrient removal areas, the 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. 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 Benefit will be achieved through the restoration of buffer areas which will infiltrate more water Water storage during precipitation events than under current site conditions. Wetland areas will provide additional storage of runoff and flood waters. 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 Benefit will be achieved by restoring riparian buffer habitat to appropriate bottomland hardwood Restoration of habitats ecosystem. Protected riparian corridors will create contiguous natural areas with uninterrupted migration corridors. 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 Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 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 Cedar Creek Stream and Wetland Restoration Project is located in the Great Coharie Creek Watershed (http://portal.ncdenr.org/web/DMS/priorities-map). This 14 -digit Hydrologic Unit Code (HUC 03003006090060) is identified as a Targeted Local Watershed (TLW) in the Cape Fear River Basin Restoration Priority (RBRP). 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 (LWP) is available for the project area. The 2009 Cape Fear RBRP identified water quality and agricultural impacts as major stressors within this TLW. The Cedar Creek 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 addressed stressors identified in the TLW, and include the following: • Water quality improvements, • Natural resource protection, and • Manage agricultural impacts. The project goals were addressed through the following project objectives: • Converting active farm fields to forested buffers, • Stabilization of eroding stream banks, • Reduction in stream bank slope, • Restoration of riparian buffer bottomland hardwood habitats, and • Construction of in -stream structures designed to improve bedform diversity.

Cedar Creek Site Project Components — Stream Mitigation 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. RES did not submit an asset revision and reverted to the Approved Mitigation Plan assets. 1.3.1 Restoration Type and Approach Stream restoration efforts along the unnamed tributaries to Great Coharie Creek were accomplished through analyses of geomorphic conditions and watershed characteristics. The design approach applied a combination of analytical and reference and/or analog reach based design methods that meet objectives commensurate with both ecological and geomorphic improvements. Proposed treatment activities ranged from minor bank grading and planting to re-establishing stable planform and hydraulic geometry. Reaches that required full restoration, natural design concepts have been applied and verified through rigorous engineering analyses and modeling. The objective of this approach was to design a geomorphically stable channel that provides habitat improvements and ties into the existing landscape. Priority Level I stream restoration, headwater valley restoration, stream Enhancement Levels I and 11, and stream buffers throughout the project site have been restored and protected in perpetuity.

Priority Level I stream restoration, headwater valley restoration, stream Enhancement Levels I and 11, and stream buffers throughout the project site have been restored and protected in perpetuity. Priority Resource Environmental Solutions, LLC 3 Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 Level I stream restoration was incorporated into the design of a single -thread meandering channel, with parameters based on data taken from the reference site. Priority 1 stream restoration was proposed on 2,416 linear feet of stream channel. Headwater valley restoration was applied to 527 linear feet of channel. Enhancement Level I was applied to 680 linear feet of channel that required buffer enhancement, bank stabilization and habitat improvements. Enhancement Level 11 was applied to an additional 4,584 linear feet of channel that required buffer enhancement and/or minimal bank and habitat improvements. UT1 UT1 flows from southeast to northwest across the project, totaling 5,186 linear feet of Enhancement Level I and 11. The upper -most portion of UTI (reaches UT1A and UT1B) is stable and has a forested buffer along both banks; however, privet was dominant within the right buffer. The downstream portion of UT1 (reaches UTIC, UTD and UT1E) was moderately stable and exhibited some areas of localized erosion prior to mitigation activities. The buffer along this section consisted of a five year old clear-cut along the left bank and cultivated fields along the right bank. A 60 -foot easement break is present within the downstream section (ME) to account for an existing farm crossing which has been upgraded. 680 linear feet of Enhancement Level I was performed along reach UTL Selective locations were identified to include streambed structures, minor bank grading, planting a native stream buffer and invasive species control. Primarily, Stabilization/Enhancement 11 activities included performing minor bank grading, planting the buffer with native vegetation, and invasive species control. UT2 UT2 is the middle tributary of the project, totaling 337 linear feet of headwater valley restoration along the upstream section and 518 linear feet of Priority 1 restoration through the downstream section. The upper section of the channel was channelized and bordered by cultivated fields to the northwest and a pine stand to the southeast, while the lower portion was a small ditch surrounded by cultivated fields. The headwater valley portion relocated the flow path to the natural valley (to the left of the existing ditch), and the abandoned ditch has been back filled. The performed P 1 restoration included relocating the channel to follow the natural valley and emptying into Cedar Creek near STA 25+50. A 60 -foot easement break crossing is present at STA 4+66 along UT2. Twin 24" HDPE culverts were installed within the easement break crossing. Restoration activities included constructing a meandering channel, installing habitat and drop structures, filling and plugging the abandoned channel, planting the buffer with native vegetation, and invasive species control. UT2C UT2C is also located in the middle of the project (adjacent to UT2), totaling 193 linear feet of headwater valley restoration. The upstream end of the reach begins at an existing wetland that borders a farm path to the north. Flow from the wetland originally had been diverted to a ditch that ran east -west along the farm path before it was conveyed across the path and into UT2 near the upstream end. Restoration activities involved redirecting channel flow to the natural valley and grading out the existing ditch and path such that the area matches existing grade on either side of the path. Additional activities included planting the buffer with native vegetation and invasive species control. UT3 UT3 is the western most tributary of the project, totaling 1,941 linear feet of Priority 1 restoration. The upper section of the channel was incised/oversized and began at a pond outlet east of the airport and flowed through a wooded area consisting of saplings and some mature hardwoods, while the lower section flowed through a cultivated field. The restored channel has been relocated to the west to follow the natural valley, and now flows through the middle of the wetland restoration area (Wl). UT3 now outlets into Cedar Creek near STA 43+10. Restoration activities included constructing a meandering channel, installing habitat and grade control structures, filling and plugging the abandoned channel, Resource Environmental Solutions, LLC Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 planting the buffer with native vegetation, and invasive species control. Small ditches located adjacent to UT3 and within the conservation easement have also been plugged and filled to redirect and diffuse flow through the wetland restoration area and/or into UT3. UT4 UT4 is the eastern most tributary of the project, totaling 78 linear feet of Enhancement Level II. The reach was relatively stable, but had been historically channelized. The buffer along this section consisted of an agricultural field along the right bank, and a forested buffer along the left bank; however, privet was common within the left buffer. Stabilization/Enhancement II activities included performing minor bank grading, cutting a floodplain bench, and planting the buffer with native vegetation, and invasive species control. Wetland W1 This 13.72 -acre wetland is located along UT3 and where it reaches the confluence of with UT 1 Reach E. The pre -restoration land use was sparsely wooded and active cropland. Wetland restoration activities consisted of removing valley fill, filling drainage ditches, removing subsurface drainage tiles, and raising adjacent stream channels to reconnect the floodplain with seasonal and out of bank flows. Raising the stream bed will also reduce the "dry shoulder" effect near the stream channel. Specific wetland restoration activities included: reconnecting low lying areas of hydric soil with the floodplain, plugging agricultural drainage ditches, planting native tree and shrub species commonly found in small stream swamp ecosystems, and surface roughening to increase infiltration and storage. Wetland restoration activities also included the breaching, backfilling, and planting of an old pond (0.22 acres) that was identified after Mitigation Plan approval. The IRT has not approved these additional 0.22 acres therefore RES will revert back to the 13.10 WMUs from the Approved Mitigation Plan. Wetland restoration limits and hydroperiods will be determined by on-site soil investigations and hydrologic modeling in conjunction with pre -construction water table monitoring at the restoration sites and reference wetlands. Combined with the stream restoration, these actions will result in a sufficiently high water table and flood frequency to support hydrophytic vegetation and wetland hydrology, resulting in restored riparian wetlands. 1.4 Project History, Contacts and Attribute Data 1.4.1 Project History The Cedar Creek Stream and Wetland Restoration Site was restored by Resource Environmental Solutions, LLC (RES) through a full -delivery contract awarded by NCDMS in 2012. 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 42.0 acres and is broken into four tributaries, UT 1, UT2, UT3, and UT4. The land use in the 2,778 -acre (4.34 mit) project watershed that drains to UT 1 consisted of row crop production, livestock production, silviculture, and sand mining areas. Past land use practices caused increased erosion and sedimentation along drainage -ways and stream banks in the watershed. UT2 has a drainage area of 32 acres (0.05 mit) and flows southwest into UT I. Land use in this small drainage area consisted entirely of row crop production and disturbed hardwood forest. UT2 originated in a disturbed hardwood forest and flows through a cultivated field to its confluence with UT 1. UT3 has a drainage area of 147 acres (0.23 mit) and flows south into UTI. Land use in this drainage area consisted of row crop production, historical and future livestock production, disturbed hardwood Resource Environmental Solutions, LLC Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 forest, maintained open space, and impervious surfaces associated with residential commercial development. Portions of the Sampson County Airport, including parts of the runway, terminal, and apron areas, lie within the UT3 drainage area. UT3 originates at a pond that is adjacent to the airport property. This reach flowed through a disturbed hardwood forest, and then through a cultivated field to its confluence with UTI. UT4 has a drainage area of 77 acres (0.12 mi2), originates within a disturbed hardwood forest, and flows southwest into UT Land use in this small drainage area consisted of a mix of row crop production and disturbed hardwood forest located primarily along the drainage way. UT2, UT3 and UT4 were straightened, dredged, or re -aligned in the past to promote drainage. Soil investigations showed that much of the low-lying landscape adjacent to UTI and its confluences with UT2 and UT3 exhibited hydric characteristics and a shallow seasonal high water table. The low lying fields in this area were considered prior converted wetlands (PC) that were drained and are currently utilized for row crop and livestock production. The land use in the watershed is characterized by evergreen forest (47 percent), cultivation (31 percent), woody wetlands (9 percent), open space (8 percent) and shrub/scrub (5 percent). 2 Success Criteria The success criteria for the Cedar Creek Site stream restoration 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 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 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 Resource Environmental Solutions, LLC Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 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). 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 seven 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. 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). Resource Environmental Solutions, LLC Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 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 Three sets of manual and auto -logging crest gauges were installed on the site, one along UT2, one along UT2C, and one along UT3. 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 27 permanent cross sections were installed to monitor channel dimensions and stability. Cross sections were typically located at representative riffle/shallows and pool sections along each stream reach. Four cross sections were installed along UTI where enhancement activities were performed. Eight cross sections (three pools, two runs, and three shallows) were installed along UT2. UT2C has one cross section installed throughout its length. Stream reach UT3 has 14 cross sections installed along its length where stream restoration was performed. 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 UT2 and UT3. 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. Resource Environmental Solutions, LLC Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 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 reaches on UT2 and UT2C 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 gauges 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. 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 fourteen automatic recording pressure transducers (Auto -Wells) have been installed on the site. Eleven 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 20 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. Resource Environmental Solutions, LLC Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 4.1 Stream No stream problems were identified in MY4. The three stream problem areas noted in MY3 were repaired in October 2018. The log outlet structure at the confluence of UT -1 and UT -2 was fixed as well as the double log drop before the confluence of UT -3 and UT -1. Also the localized areas of bank erosion on UT -1 were stabilized with livestakes and matting and a brush toe was added to one localized problem area. 4.2 Wetlands No wetland problems areas were noted during the Year 4 monitoring period. The ditch between AW8 and AW7 was plugged in October 2018. 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 as part of the annual monitoring report. 4.3 Vegetation One vegetation problem area remained during the Year 4 monitoring period. The vegetation problem area is mapped on the Current Conditions Plan View (CCPV) as part of the annual monitoring report. The vegetation problem area (VPA1) consists of a 0.5 -acre area of invasive species Chinese Privet (Ligustrum sinense) at the upstream portion of UT -1. Invasive treatment (cutting and spraying) was completed again in August 2018 and will continue as necessary in following years. The other vegetation problem area reported in MY3 was a small sparse herbaceous vegetation area along UT -2 above the stream crossing (Sta. 4+00). This area was reseeded, mulched, and replanted in October 2018. 5 YEAR 4 MONITORING CONDITIONS (MY4) The Cedar Creek Year 4 Monitoring activities were completed in late August 2018. Year 4 wetland, stream hydrology, and vegetation monitoring data is present below and in the appendices. Per the Approved Mitigation Plan, cross section monitoring was not performed in Year 4. Data presented shows the site has no stream problem areas and one vegetation problem area; however, the site is on track to meeting stream, wetland and vegetation interim success criteria (Figure 3). 5.1 Year 4 Monitoring Data Collection 5.1.1 Morphological State of the Channel Per the Approved Mitigation Plan, cross section monitoring was not performed in Year 4. Visual monitoring, however, was performed and no new problems were found in Year 4. Problems from previous years were repaired in October 2018 and are discussed in section 4.1. 5.1.2 Vegetation The Year 4 monitoring vegetation survey was completed in late August 2018 and resulted in an average of 652 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 16 planted stems. The minimum planted stem per plot was nine stems and the maximum was 31 stems per plot. Six volunteer tree species were noted during MY4 activities. The average planted stem height was 5.6 feet. Vegetation summary data tables can be found in Appendix C and vegetation plot photos in Figure 5. 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 Resource Environmental Solutions, LLC 10 Cedar Creek Stream and Wetland Restoration • USGS HUC 03030006 Year 4 Monitoring Report • Sampson County, North Carolina • January 2019 also be documented with a digital photograph during monitoring activities. Stream digital photographs can be found in Figure 4 and Figure 5 for vegetation photos. 5.1.4 Stream Hydrology Three sets of manual and auto -logging crest gauges were installed on the site, one along UT2, one along UT2C, and one along UT3. The auto logging crest gauges were installed within the channel and continuously record flow conditions at hourly intervals. Crest Gauge 1 and Crest Gauge 3 documented bankfull events towards the end of Year 4 monitoring period. With the bankfull events in 2018, the site has now met the bankfull standard. Crest Gauge 2, on the headwater valley restoration reach UT -2C, documented 57 consecutive and 168 total flow days. Stream hydrology data can be found in Appendix E. 5.1.5 Wetland Hydrology Eight of the eleven 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 indicate the hydroperiods being very responsive to rainfall events. Wetland hydrology gauge AW7 fell short of the nine percent success criteria. AW7 documented 7 days consecutively (3%) throughout the growing season. RES plugged the ditch adjacent to AW7 to make sure wetland hydrology is met in this area in future years. AW8 and AW11 fell short of the success as well but stayed above the five percent hydroperiod for jurisdictional wetlands with eight percent. All three reference gauges documented hydroperiods well above the nine percent success criteria ranging from 15 to 23 percent of the growing season. Wetland gauge and rainfall data is presented in Table 15 and Figure 8. 6 REFERENCES Chow, Ven Te. 1959. Open -Channel Hydraulics, McGraw-Hill, New York. Cowardin, L.M., V. Carter, F.C. Golet and E.T.

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 Yellow 4.
