Documentation of Geomorphically Significant Flow Events Crest Gauge Reading Photos 1.0 Proiect Summary 1.1 Project Location and Description The Polecat Mitigation Site (the "Site") is located within a watershed dominated by agricultural land use in Johnston County, North Carolina, approximately two miles southeast of Smithfield. The project streams were significantly impacted by livestock access, row crop production, and nearby urbanization. The project involves the restoration and protection of streams in the Neuse River watershed. The purpose of this Site is to restore and enhance a stream complex located within the Neuse River Basin. The Site lies within USGS Hydrologic Unit Code (HUC) 03020201140010 (USGS, 2012). The 2010 Neuse River Basin Restoration Plan (RBRP) identified the Neuse River watershed (HUC 03020201140010) as a Targeted Local Watershed (TLW), a watershed that exhibits both the need and opportunity for wetland, stream, and riparian buffer restoration. The Site supports many of the Neuse River RBRP and Neuse Regional Watershed Plan (RWP) goals. The Project's watershed is primarily rural with Interstate 95 occupying the western portion of the watershed. The Project parcels have been in agricultural use for several decades. The Site is located within HUC 03020201 and includes streams that directly discharge into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in -stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. Water quality stressors that affected the Site included livestock access, row crop production, and impervious surface. The project presents 8,178 linear feet of stream restoration and enhancement generating 6,567 Stream Mitigation Units (SMU). The areas adjacent to the Site consist of agricultural fields, cattle pastures and wooded areas. The total easement area is 53.63 acres. Invasive species were present throughout the wooded areas and will continue to be treated throughout the monitoring period. Channels restored were incised, both laterally and vertically unstable, impacted by cattle, lack riparian buffers, and aquatic life was not supported. Stream conditions along the restoration reaches exhibited habitat degradation because of impacts from livestock and nearby impervious surfaces because of urbanization. After completion of all construction and planting activities 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 is the survival of at least 210 seven-year old planted trees per acre with an average height of 10 feet at the end of year seven of the monitoring period. Upon approval for closeout by the Interagency Review Team (IRT), the Site will be transferred to the North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will be responsible for periodic inspection of the Site to ensure that restrictions required in the Conservation Easement or the deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions will be negotiated prior to site transfer to the responsible party. Polecat 2 Year 2 Monitoring Report Stream Mitigation Site October 2019 1.2 Project Goals and Objectives The 2010 Neuse River RBRP identified several restoration needs for the entire Neuse River Basin, as well as for I UC 03020201. The Polecat Creek watershed (HUC 03020201140010) was identified as a TLW, a watershed that exhibits both the need and opportunity for wetland, stream, and riparian buffer restoration. The Polecat Creek watershed includes 42 square miles of watershed area. Twenty percent of the watershed is used for agricultural purposes and three percent is currently developed. The Site was identified as a stream and buffer restoration opportunity to improve water quality, habitat, and hydrology within the Neuse River Basin. The Site is located within I UC 03020201 and includes streams that directly discharge into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in -stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. The project goals 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, and root wads, • Preservation and enhancement of hydrology in existing riparian wetlands, 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 the "Wilmington District Stream and Wetland Compensatory Mitigation Update" dated October 24, 2016. Cross section and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported annually. Stream Success Criteria Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull events have been documented in separate years. Stream restoration reaches will be monitored to document intermittent or seasonal surface flow. This will be accomplished through direct observation and the use of stream flow gauges with data loggers. Reaches must demonstrate a minimum of 30 consecutive days of flow. 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 Polecat 3 Year 2 Monitoring Report Stream Mitigation Site October 2019 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 1.4 within restored reaches. Channel stability should be demonstrated through a minimum of four 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 series of images over time should indicate successional maturation of riparian vegetation. 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 occur between July 1st and leaf drop and includes II permanent vegetation plots and three random vegetation plots. 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. 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 location along multiple drainage features that flow into the Neuse River. The northern easement area captures two tributaries to Polecat Branch and a portion of its headwaters. The southeastern easement area is separated from the northern area by a 100-foot crossing, and is divided into three different areas due to a gas line easement and a telephone line easement. The stream mitigation components are summarized in Table 1, as well as Figure 2.

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 to identify the design discharge. The Site includes Restoration, Enhancement Level I, Enhancement Level II and Enhancement Level III. Restoration was done along reaches MI1, KZ2, KZ3, KZ4, KZ5, and KZ6. Restoration reaches typically include a meandering single -thread stream pattern constructed to mimic the natural planform of a low - gradient, sand/gravel bed channel. Sinuosity depends on local reference reach conditions and hydrologic and hydraulic modeling. As a result of the restoration of planform and dimension, periodic flooding and Polecat 5 Year 2 Monitoring Report Stream Mitigation Site October 2019 restored riparian buffer provide the appropriate hydrology and sediment transport throughout this watershed. Enhancement Level I was done on Reach KZ4; Enhancement Level II and III was done along Reaches KZ0, KZ1, PC1, PC2, and PC3. Enhancement Level I includes adjustments to the cross -sectional area of the existing channel and floodplains, as well as installations of wood and rock structures to adjust and enhance bedform. Enhancement Level II treatments include livestock exclusion and bank stabilization. Enhancement Level III allows high quality aquatic habitat to be protected and enhanced through invasive species treatments and supplemental plantings in the riparian buffer. 1.6 Construction and As -Built Conditions Stream construction and planting was completed in May 2018. The Polecat Mitigation Site was built to design plans and guidelines. No major changes or modifications were made during construction activities. The fence and crossings were completed in June 2018. Baseline channel length and stationing is based on design centerline. 1.7 Year 2 Monitoring Performance The Polecat Year 2 Monitoring (MY2) activities were completed in September 2019. All Baseline Monitoring 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 11 permanent vegetation plots and three random vegetation plots was completed during September 2019. Vegetation data are in Appendix C, associated photos are in Appendix B, and plot locations are in Appendix B. MY2 monitoring data indicates that all plots are exceeding the interim success criteria of 320 planted stems per acre. Planted stem densities ranged from 445 to 1,133 planted stems per acre with a mean of 846 planted stems per acre across the permanent plots. A total of 11 species were documented within the plots. Volunteer species were observed in two plots. The average tree height observed was 3.8 feet. Vegetation data from the three 100 square meter (25 meter x 4 meter) random belt transects showed 648 stems per acre in Random Plot 1, 688 stems per acre in Random Plot 2, and 891 stems per acre in Random Plot 3. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. One area of encroachment was observed along the edge of the easement near the non jurisdictional ditch upstream of KZ5. This area is approximately 0.22 acres and is completely in the DWR portion of the project. RES used logs as a physical barrier on the edge of the easement, but these logs were moved as part of the encroachment. RES will communicate with the farmer as well as move the logs back to the edge of the easement to prevent future encroachment. The area is shown on Figure 2, labeled VPA1. Stream Geomorphology Geomorphology data for MY2 was collected during September 2019. Summary tables and cross section/profile plots are in Appendix D. Overall the MY2 cross sections relatively match the as -built conditions. Minor adjustments are expected during the first few years after construction. Bank height ratios remain less than 1.2 and entrenchment ratios greater than 1.4. Polecat 6 Year 2 Monitoring Report Stream Mitigation Site October 2019 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. The bank erosion area that was observed and reported in MY did not worsen in MY2 and is stable, as vegetation continued to grow and strengthen the bank. Stream Hydrology Flow and crest gauges are located on Reaches KZ2, KZ6, and MI1. There were 14 total bankfull events recorded on site in MY2; two on KZ2, two on KZ6, and 10 on MI1. Gauge locations can be found on Figure 2 and data are in Appendix E. 2.6 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 22 cross -sections. Survey data was imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. In May 2018 three sets of crest gauges and flow gauges were installed along the main project channel. The flow gauges were installed within the channel and will 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. If there are no corkline readings on the crest gauges, the height of the top of bank and water depth can be used to produce bankfull readings from the HOBO data. Vegetation success is being monitored at 11 permanent monitoring plots and three random monitoring plots. Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and density of planted species. Data 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. The random plots are collected in the planted Non -Standard Buffer Width areas as 100 square meter belt transects. To measure the belt transects, a meter tape is stretched diagonally across the rows of trees and any tree that falls within width of the transect is recorded. The transects will be mapped and new locations will be monitored in subsequent years.
