More specifically, the Conservation Easement (CE) for the Stream Restoration project is 7.01 acres in size and starts just south of NC Highway 147, runs parallel to Campus Drive, crosses Campus Drive and ties back in to the receiving waters at Oregon Street (Appendix A, Figures 2.1 and 2.2). The Stream Restoration project is approximately 1.5 miles from the proposed stream impacts associated with the Duke University water reclamation pond. The Stream Restoration project is located within the Cape Fear River Basin USGS Hydrologic Unit 03030002 (USGS 1974), local watershed 14-digit basin 03030002060110, and the North Carolina Division of Water Resources (DWR) sub -basin 03-06-05. The unnamed tributary flows directly into Sandy Creek (DWR stream index number of 16-41- 1-11) approximately 2.5 miles downstream of the project terminus. The drainage area of the unnamed tributary is approximately 141 acres at the downstream end. Based on a detailed watershed analysis, approximately 27 percent (39 acres) of the watershed area is impervious. The Stream Restoration project is located within the Piedmont Physiographic Province of North Carolina. A review of the Ecoregions of North Carolina and South Carolina (Griffith et al., 2002) shows the geology of the Stream Restoration project is comprised of quaternary to tertiary red sandy loam to silty clay decomposition residuum, sandstone, conglomerate, mudstone, shale, coal, dikes, and sills within the Triassic Basin. There are currently no agricultural croplands or activities within the watershed; however, there was stream channelization and relocation associated with the sanitary sewer line installation adjacent to the unnamed tributary. 1.2 Project Goals and Objectives The purpose of this Stream and Vegetation Monitoring Year 6 report is to assess the Stream Restoration project in order to determine restoration success. The monitoring plan to evaluate the success of the Site is based the U.S. Army Corps of Engineers (USACE) Stream Mitigation Guidelines (April 2003) and the North Carolina Ecosystem Enhancement Program (NCEEP) Monitoring Requirements and Performance Standards for Stream and/or Wetland Mitigation (November 2011). Monitoring of the Site will occur annually for seven (7) full years. Construction of the Stream Restoration project occurred in the summer of 2013. Riparian buffer restoration activities, which included planting trees and staking vegetation plots within the CE, began in November 2013 following construction of the restored active stream channel. The goal of the stream restoration project is to modify the dimension, pattern, and profile of the channel so that a stable and self -maintaining channel is created by utilizing natural channel design techniques and procedures. The design was developed utilizing Rosgen-based natural channel design principles (Rosgen, 1996). Preventing future stream bank erosion will be accomplished by fulfilling the following general objectives: 1) Conversion of approximately 3,459 linear feet of the tributary from an eroding, degraded channel to a natural, stable system with restored aquatic habitat. 2) Reduction of sediment loading to a river system that flows into Jordan Lake - a recreational water body. 3) Establishment of a riparian corridor that has a restored floodplain, aquatic, and morphological functions which provide habitat connectivity to the area and will be protected in perpetuity. creating experiences through experience 1 of 6 2 MCADAMS WATER RECLAMATION POND STREAM RESTORATION > MONITORING YEAR 6 REPORT The following specific objectives will allow the restoration plan to succeed in obtaining the project's goal: 1) Design a channel with the appropriate cross -sectional dimension, pattern and longitudinal profile utilizing the existing channel condition survey and collected reference reach data as a guide. 2) Improve upon and create bedform and aquatic habitat diversity (riffles, runs, pools and glides). 3) Create a nested floodplain (bankfull bench) that will be accessible at the proposed bankfull channel elevation along the entire reach. 4) Ensure channel and stream bank stabilization by integrating in -channel grade control structures and native vegetation into the proposed restoration design while also creating a stable and functional aquatic and terrestrial habitat. 5) Establish a native forested riparian plant community within a minimum of 50 feet from the proposed top of the bankfull channel along with the removal of exotic vegetation during construction implementation and the elimination of current embankment maintenance practices. 2.0 CHANNEL STABILITY ASSESSMENT Channel stability will be reflected in the surveyed permanent cross -sections, longitudinal profile, evaluation of bank stability and cover, evaluation of in -stream structure performance and to a lesser degree pebble counts compared to the as -built and any previously collected monitoring data. The general trend should reflect a stable or slightly decreasing riffle cross -sectional area whereas pools may increase and yet be considered relatively stable. The longitudinal profile will typically adjust depending on the frequency of bankfull or greater storm events. Normally, the constructed channel profile will adjust (especially in a sand dominated bed) but it will need to function without significant degradation (bed scour), aggradation (mid -channel bars) or bank erosion. The Bank Height Ratio (BHR) shall not exceed 1.2 and the Entrenchment Ratio shall be no less than 2.2. The stream shall remain stable over seven years and through two bankfull events as indicated by visual surveys, cross -sections and bank pins. If monitoring (including vegetation) demonstrates success by year five (5), a proposal can be issued by the Owner to terminate monitoring of the site. 2.1 Cross Sections and Longitudinal Profile The stream geometry will be considered successful if the cross-section geometry, profile and sinuosity are stable or reach a dynamic equilibrium. It is expected there will be minimal changes in the designed cross sections, profile and/or substrate composition. Changes that may occur during the monitoring period were evaluated to determine if they represent a movement toward a less stable condition (e.g. down cutting, erosion, mid- channel bars, etc.) or are minor changes that represent an increase in stability (e.g. settling, vegetative changes, coarsening of bed material, etc.). Deviation from the design ratios will not necessarily denote failure, as it is possible to maintain stability and not stay within the design geometry. Cross section survey data will be collected and reported in years 1, 2, 3, 5 and 7. The longitudinal profile will be surveyed in years 1 and 7. Neither the longitudinal profile nor cross sections were surveyed as part of the Monitoring Year 6 field assessment. 2.2 Pebble Counts The composition of the streambed and banks is an important facet of stream character, influencing channel form and hydraulics, erosion rates, sediment supply and other parameters. The most efficient basic technique in measuring the streambed and banks is the Wolman Pebble Count method. This requires measuring individual substrate particles along a cross section and tallying the size class of each particle. Pebble counts are conducted to determine bed particle size distribution at each riffle cross section (Cross Sections 1, 3, 6 and 9). Pebble Counts creating experiences through experience 2 of 6 111 MCADAMS WATER RECLAMATION POND STREAM RESTORATION > MONITORING YEAR 6 REPORT will be conducted and reported in years 1, 2, 3, 5 and 7. Pebble counts were not collected as part of the Monitoring Year 6 field assessment. 2.3 Crest Stage Gauge A Crest Stage Gauge (CSG) was installed during Monitoring Year 1 field activities to document bankfull events. The CSG was installed at Station 15+57 near Vegetation Plot 5 (Appendix A, Figures 2.1 and 2.2). CSG measurements will be conducted and reported in all years of monitoring. A CSG measurement of 2.8 feet was recorded during the Monitoring Year 6 field assessment. Table 1 provides a list of bankfull events based on the installed CSG and observed indicators of overbank flow. Table 1.

The bank pins were installed so that they can be measured over time in order to observe changes in the stream bank profile. Bank pin measurements can then be used to estimate rates of erosion and sediment loading. Bank pin measurements will be conducted and reported in years 1, 2, 3, 5 and 7. Bank pin measurements were not collected as part of the Monitoring Year 6 field assessment. 2.5 Channel Stability Assessment Summary As part of the Monitoring Year 6 field assessment, the entire stream restoration project was visually inspected. Below is a summary and recommendations based on the visual inspection. > As noted in previous years, mowing activities continue to occur within the Northern and Central sections of the CE. Mowing within the CE needs to cease immediately for the project to receive full credit upon close out. > Two large trees have fallen across the channel and sanitary sewer easement in the Southern section of the stream restoration project. These trees may create obstructions in the channel that could lead to bank erosion during high flows and cause stability issues. It is recommended that the fallen trees be removed from the channel. > There are several areas of bank erosion primarily within the Northern section of the site. Moderate erosion was noted at several log sills in the Northern section in Monitoring Years 4 and 5, and these areas have continued to experience erosion in Monitoring Year 6. Repairs are scheduled for winter of 2020. It is recommended that the log sill repairs be completed as scheduled and that stream banks, particularly in the Northern section of the site, continue to be monitored for stability. creating experiences through experience 3 of 6 111 MCADAMS WATER RECLAMATION POND STREAM RESTORATION > MONITORING YEAR 6 REPORT 3.0 VEGETATION CONDITION AND COMPARISON The primary focus of the vegetative monitoring will be solely on the tree stratum, although shrub and herbaceous species encountered may also be recorded. Vegetation planting success criteria will be based on the survival of a minimum density of 320 trees per acre (to include both planted and existing trees) after three (3) years of monitoring. After five (5) years of monitoring, the density shall be no less than 260 trees per acre (to include both planted and existing trees). After seven (7) years of monitoring, the density shall be no less than 210 trees per acre (to include both planted and existing trees). In addition, planted vegetation must average 10 feet in height in each plot at year seven (7). If the height standard is met and the stem density is trending toward success after five (5) years of monitoring, monitoring of vegetation on the site may be terminated provided written approval is provided by the USACE and NCDWQ. In Monitoring Year 6, the average height of planted vegetation exceeded 10 feet in two of six plots. 3.1 Vegetation Monitoring Plots All vegetation monitoring methodologies followed the most current templates and guidelines provided by DMS (EEP, 2010; EEP, 2011). Baseline vegetation monitoring was conducted in accordance with CVS-EEP Protocol for Recording Vegetation (CVS-EEP, V4.2). All six (6) vegetation monitoring plots installed by McAdams were located in Monitoring Year 6. Figures 2.1 and 2.2 (Appendix A) depict the location of the vegetation monitoring plots. Plant species, density, survival rates and the cause of mortality, if identifiable, were recorded within each vegetation monitoring plot. Table 1 (Appendix B) provides a success summary for each vegetation monitoring plot. In Monitoring Year 6, the Stream Restoration project had six (6) vegetation monitoring plots encompassing 0.1483 acres, containing 63 planted stems, which yielded a density of 425 planted stems per acre. Monitoring Year 6 field activities were conducted on December 5 and December 10, 2019. The planted vegetation survival threshold was met for all six vegetation monitoring plots. Table 2 (Appendix B) provides a summary of the planted stem counts for each vegetation plot. Table 3 (Appendix B) provides a summary of planted stem survival compared to the As Built. 3.2 Vegetation Monitoring Plot Photos and Data Sheets Photographs of the vegetation monitoring plots are in Appendix C. Vegetation Monitoring Plot Data Sheets are provided in Appendix D. Each Vegetation Monitoring Plot Data Sheet provides measurements, location and vigor of each planted species within a respective vegetation monitoring plot. 3.3 Photo Stations Photo documentation is essential to monitoring the success of the Bank Parcel. Photos provide a visual assessment of the vegetation conditions. Photo documentation will be provided and reported in all years of monitoring. All nine (9) photo stations installed by McAdams were located in Monitoring Year 6. Figures 2.1 and 2.2 (Appendix A) depict the locations of the photo stations. Photographs were taken at high resolution using an iPhone 7 camera. Photographs for the photo stations are located in Appendix E. 4.0 INVASIVE SPECIES MONITORING Construction of the Stream Restoration project required disturbing land within the CE resulting in the creation of a highly disturbed early successional ecological system that contains tree sapling and shrub species in addition to naturally occurring early emergent vegetative species. Over time, tree sapling and shrub species mature and proliferate while naturally occurring early emergent vegetative species dwindle. creating experiences through experience 4 of 6 2 MCADAMS WATER RECLAMATION POND STREAM RESTORATION > MONITORING YEAR 6 REPORT The new, highly disturbed, early successional ecological system created during the construction of Stream Restoration project resulted in prime habitat for many invasive species that were known to occur within the CE prior to construction activities, in addition to the surrounding areas (Invasive Species Management Plan, May, 2014). It is understood that naturally occurring, early emergent vegetative species will thrive within the CE during the early years of the Stream Restoration project. The early emergent vegetative species can be aggressive and have characteristics of an invasive species; however, they are generally accepted as part of a naturally occurring ecological system. Therefore, a definition of what is an invasive species is warranted. Invasive Species are defined as non-native alien species that have the potential to negatively affect the environment. These species occupy habitat within the riparian buffer and outcompete and suppress native vegetation, thereby inhibiting both the establishment and natural succession of the native riparian community. Considerable effort was made to remove most of the observed invasive species populations during the construction phase of the Stream Restoration project by both mechanical and chemical means. Although considerable effort was made to remove the invasive plants species from within the CE, remnant populations of these invasive species were recorded in a post construction site visit conducted in May 2014. Future treatment is likely to be required for the observed invasive species, but additional invasive species may expand the list. As part of the stream and vegetation monitoring efforts in previous years, invasive species monitoring and treatment have been conducted in the spring and fall. However, invasive species monitoring and treatment efforts for Monitoring Year 6 have been postponed until the scheduled log sill repairs have been completed with the intention of minimizing disturbance. Invasive species monitoring and treatment is scheduled to resume in the spring of 2020, by which time the repairs are expected to be complete. creating experiences through experience 5 of 6 111 MCADAMS WATER RECLAMATION POND STREAM RESTORATION > MONITORING YEAR 6 REPORT 5.0 REFERENCES Lee Michael T., Peet Robert K., Roberts Steven D., and Wentworth Thomas R., 2008.
