Documentation of Geomorphically Significant Flow Events Crest Gauge Reading Photos MY1 Headwater Valley Restoration Stream Flow Hydrograph 1.0 Proiect Summary 1.1 Project Location and Description The Selma Mill Stream Mitigation Site (the "Site") is located within a watershed dominated by agricultural and residential land use in Johnston County, North Carolina. Prior to construction, the project streams were significantly impacted by channelization and agricultural practices. The project involves the restoration and protection of streams in the Neuse River watershed. The purpose of this mitigation site is to restore and enhance a stream/wetland complex located within the Neuse River Basin. The Site has been designed in concurrence with the Selma Mill Riparian Buffer and Nutrient Offset Mitigation Bank. EBX-Neuse I, LLC ("EBX"), acting as the Bank Sponsor, established a Conservation Easement and will monitor the Site for a minimum of seven years in accordance with the terms and conditions of the Neu -Con Wetland and Stream Umbrella Mitigation Bank. The Site is in Johnston County immediately north of Selma, NC (Figure 1). The latitude and longitude for the site is 35.547353 ON and -78.282503 °W. The site extends approximately 2,300 feet north on the west side of NC HWY 96 beginning immediately north of W Chestnut Street. A tributary crosses NC HWY 96 approximately 1,900 feet north of W Chestnut Street and extends approximately 1,600 feet west. The Site consisted of stream restoration on tributaries that drain directly to Mill Creek. The project presents 6,771 linear feet of Stream Restoration generating 7,305 Stream Mitigation Units (SMU). A combination of Priority 1 and Priority 2 restoration was used on Reaches A and B and Headwater Valley Restoration on Reach C. Benefits include the storage of excess water during flood events, preventing erosion of stream banks, reducing in -stream sedimentation, and nutrient reductions. SMU totals were adjusted using the most recent non-standard buffer width guidance documents. The Site consisted of agricultural fields, cattle pastures and wooded areas. The total easement area is 34.2 acres. The wooded areas along the easement corridor designated for restoration activities are classified as mixed pines and hardwoods. Invasive species are present throughout the wooded areas. Restoration channels were degraded to a point where they could no longer access their floodplain, lack riparian buffers, allow livestock access, and aquatic life was not supported. Little aquatic habitat was available to support aquatic life, and the riparian buffers were not maximizing their potential to filter nutrients. The Site will be monitored on a regular basis and a physical inspection of the site will be conducted at a minimum of twice per year throughout the seven-year post -construction monitoring period, or until performance standards are met. These site inspections will identify site components and features that require routine maintenance. The measure of stream restoration success will be documented by bankfull flows and no change in stream channel classification. Sand bed channels are dynamic and minor adjustments to dimension and profile are expected. The measure of vegetative success for the site will be the survival of at least 210 seven-year old planted trees per acre with an average height of 10 feet at the end of year seven of the monitoring period. Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to the North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will be responsible for periodic inspection of the site to ensure that restrictions required in the Conservation Easement or the deed restriction document(s) are upheld. Selma Mill 2 Year 1 Monitoring Report Stream Mitigation Site December 2018 1.2 Project Goals and Objectives The 2010 Neuse River Basin River Basin Restoration Priorities (RBRP) identified several restoration needs for the entire Neuse River Basin, as well as for HUC 03020201, specifically. The Site was identified as a stream restoration opportunity to improve water quality, habitat, and hydrology within the Neuse 01 River Basin. The project goals address stressors identified in the TLW and include the following: • Nutrient removal, • Sediment removal, • Invasive species treatment, • Filtration of runoff, and • Improved aquatic and terrestrial habitat. The project goals will be addressed through the following project objectives: • Exclusion of livestock, • Treatment of exotic invasive species, • Restoration of forested riparian stream buffers, • Stabilization of eroding stream banks due to lack of vegetation and livestock hoof shear, • Addition of large woody debris, such as log vanes, log weirs, root wads, • Preservation and enhancement of hydrology in existing riparian wetland seeps, and • Restoration of appropriate pattern, dimension, and profile in stream channels. 1.3 Project Success Criteria The Site follows the USACE 2003 Stream Mitigation Guidelines and subsequent guidance. The Mitigation Plan was approved in August 2016 and therefore does not adhere to the 2016 Wilmington District Stream and Wetland Mitigation Update. Cross section data will be reported in Years 0, 1, 2, 3, 5, 7, and vegetation and stream hydrology data will be reported annually. Stream Success Criteria 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. There should be little change in as -built cross-sections. If changes do take place, they should be evaluated to determine if they represent a movement toward a less stable condition (for example down -cutting or erosion), or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross-sections shall be classified using the Rosgen stream classification method, and all monitored cross-sections should fall within the quantitative parameters defined for channels of the design stream type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 2.2 within restored reaches. Channel stability should be demonstrated through a minimum of two bankfull events documented in the seven-year monitoring period. Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should not indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A Selma Mill 3 Year 1 Monitoring Report Stream Mitigation Site December 2018 series of images over time should indicate successional maturation of riparian vegetation. Headwater valley restoration reaches will be monitored to document intermittent or seasonal surface flow. This will be accomplished through direct observation, photo documentation, and the use of stream gauge transducers with data loggers. Reaches must demonstrate a minimum of 30 consecutive days of flow. Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the site will follow IRT Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size, and cover a minimum of two percent of the planted area. Vegetation monitoring will take place annually between July 15 and leaf drop. The interim measures of vegetative success for the site will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 five-year old trees at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre with an average height of 10 feet at the end of Year 7. The site includes 25 monitoring plots to monitor the 29.8 planted acres. Volunteer trees will be counted, identified to species, and included in the yearly monitoring reports, but will not be counted towards the success criteria of total planted stems. 1.4 Project Components The project area is comprised of a single easement area along three tributaries that flow into Mill Creek. The easement is separated by a crossing at NC HWY 96. The western portion of the project originates near the intersection of Hwy 96 and W Chestnut Street and includes Reaches A 1, A2, and B3. The eastern portion of the project is located in an agricultural field to the east of NC HWY 96. This area includes Reaches B 1, B2, and C. The stream mitigation components are summarized below and in Table 1.

Selma Mill 4 Year 1 Monitoring Report Stream Mitigation Site December 2018 1.5 Design/Approach The design approach for the Selma Mill Site combined the analog method of natural channel design with analytical methods to evaluate stream flows and hydraulic performance of the channel and floodplain. The analog method involves the use of a "template" stream adjacent to, nearby, or previously in the same location as the design reach. The template parameters of the analog reach are replicated to create the features of the design reach. The analog approach is useful when watershed and boundary conditions are similar between the design and analog reaches (Skidmore, et al., 2001). Hydraulic geometry was developed using analytical methods in an effort to identify the design discharge. Priority Level 2 restoration was done on Reaches Al, A2, B1, B2, and B3. Priority 1 Restoration was done on Reach A2 below the confluence with Reach B. For most of the restoration reaches, the channel was rerouted to adjacent natural valley features. By rerouting the channel and constructing floodplain benches, the design allows the channel frequent access to its floodplain and the opportunity to create small, depressional areas within the buffer to enhance habitat for wildlife and aquatic organisms. The headwater valley restoration approach was done along Reach C. The ditch was plugged and then backfilled to the extent possible such that cut and fill is balanced along the reach. 1.6 Construction and As -Built Conditions Stream construction was completed in August 2017. The Site was built to design plans and guidelines. No major changes or modifications were made during construction activities. Final floodplain grading was completed in May 2018 along with planting and fencing. 1.7 Year I Monitoring Performance The Selma Mill Year 1 Monitoring (MY1) activities were completed in November 2018. All MY1 data is present below and in the appendices. The Site is on track to meeting vegetation and stream interim success criteria. Vegetation . Monitoring of the 25 permanent vegetation plots was completed during November 2018. Vegetation data are in Appendix C and associated photos are in Appendix B. MY1 data indicates that 24 of the 25 plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 283 to 1,335 planted stems per acre with a mean of 874 planted stems per acre across all plots. Vegetation Plot 20 fell one tree short of the interim success criteria. The area in and around this plot as well as a small area on the other side of Reach B will be replanted in 2019. A total of 19 species were documented within the plots. Volunteer species were noted in four of the vegetation plots. The average tree height observed was 2.2 feet. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the majority of the project. The old road used to haul the excess dirt from the site along the top of Reach B, however, may need to be reseeded in 2019. RES will keep an eye on this area during future monitoring events. Additionally, the lower end of Reach A will be revisited in 2019 to treat any Chinese privet (Ligustrum sinense) that may be re -sprouting. There is a small (0.05 acre) area of encroachment along Highway 96 that RES will continue to monitor and communicate to the landowner that mowing is prohibited in the easement. Selma Mill 5 Year 1 Monitoring Report Stream Mitigation Site December 2018 Stream Geomorphology Geomorphology data for MY1 was collected during November 2018. Summary tables and cross section/profile plots are in Appendix D. Overall the MY1 cross sections relatively match the proposed design. Cross Section 19 showed about one foot of bed scour. This cross section is located in a pool, so RES is not concerned in MY1 but will continue to monitor above and below this cross section for bed degradation. Bank height ratios remain less than 1.2 and entrenchment ratios greater than 2.2. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation. Stream Hydrology Flow and crest gauges were installed on Reach A and Reach B and a flow gauge was installed on Reach C. 15 total bankfull events were recorded in 2018; 12 on Reach A and three on Reach B. The flow gauge recorded 238 consecutive flow days on the Headwater Valley Restoration Reach C. Gauge locations can be found on Figure 2 and hydrology data is in Appendix E. 2.0 Methods Stream monitoring was conducted using a Topcon GTS -312 Total Station. Three-dimensional coordinates associated with cross-section data was collected in the field (NAD83 State Plane feet FIPS 3200). Morphological data was collected at 28 cross-sections. Survey data was imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. In April 2018 crest gauges and flow gauges were installed on Reaches A and B and a flow gauge and time-lapse camera were installed on Reach C. The flow gauges were installed within the channel and will continuously record flow conditions at an hourly interval. The crest gauges were installed on the bank at the bankfull elevation. During quarterly visits to the Site, the height of the corkline will be recorded. HOBO data from the flow gauges will be corrected using bankfull recordings from the crest gauges. The time-lapse camera takes a photo every day at 12:30 pm. These photos will be used to show consecutive flow days in accordance with the flow gauge. Vegetation success is being monitored at 25 permanent monitoring plots. Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and density of planted species. Data is processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with PVC at the origin and metal conduit at the other corners. Photos of each plot are to be taken from the origin each monitoring year. Selma Mill 6 Year 1 Monitoring Report Stream Mitigation Site December 2018 3.0 Reference Environmental Laboratory. 1987.
