(Baker) restored 2,760 linear feet (LF) and enhanced approximately 943 LF of jurisdictional stream along UT to Town Creek. This report documents and presents the Year 1 monitoring data as required during the five-year monitoring period. The primary restoration goals of the project are described below: Create geomorphically stable conditions along the channels, Enhance hydrologic connections between streams and the degraded riparian buffer and overall ecosystem functionality; Restore and protect riparian buffer functions and corridor habitat in perpetuity by establishing a permanent conservation easement. Improve terrestrial habitat and reduce sediment and nutrient loading to the prof ect reaches and the Little Long Creek Watershed. To accomplish these goals, the following objectives were identified: Restore existing incised, eroding, and channelized streams by creating a stable stream channel with access to its floodplain, Improve in -stream habitat by providing a more diverse bedform with riffles and pools, creating deeper pools and areas of water re -aeration, and reducing bank erosion, Prevent cattle from accessing the project boundary by installing permanent fencing and thus reduce excessive bank erosion and undesired nutrient inputs, Plant native species riparian buffer vegetation along stream bank and floodplain areas, protected by a permanent conservation easement, to increase stormwater runoff filtering capacity, improve bank stability, and shade the stream to decrease water temperature, Control invasive species vegetation within the project area and, if necessary, continue treatments during the monitoring period. The Town Creek Restoration Project — Option B (Site) is located in Stanly County, approximately 1.5 miles west of the Town of New London, within cataloging unit 03040105 of the Yadkin Pee -Dee River Basin. The Site is located in a North Carolina Division of Mitigation Services (NCDMS) - Targeted Local Watershed (HUC 03040105060-040). Directions to the Project Site can be found in Figure 1 of Appendix A. During Year 1 monitoring, the planted acreage performance categories were functioning at 100 percent with no bare areas or low stem density areas to report. No invasive species areas of concern, exceeding the mapping threshold were documented; however, individuals stems ofLigustrum sinese (Chinese privet) were noted within the easement. These areas were located predominantly in the areas of the easement not cleared during construction and where mature woody vegetation is present. Based on data collected from the eight monitoring plots during Year 1 monitoring, the average density of total planted stems per plot ranges from 647 to 850 stems per acre with a tract mean of 754 stems per acre. Therefore, the Year 1 data demonstrate that the Site is on track for meeting the minimum success interim criteria of 320 trees per acre by the end of Year 3. Vegetation stem counts are summarized in Tables 7 and 9 of Appendix C. The thirteen (13) permanent cross-sections located throughout the Site show minimal adjustment to stream dimension since construction. In addition, Tables 5a through 5f (Appendix B) indicate the Site has remained geomorphically stable with lateral/vertical stability and in -stream structure performance of 100% on all stream reaches and no noted areas of bank scour and/or erosion around structures. Visual observations and a review MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 95026 TOWN CREEK RESTORATION PROJECT - OPTION B YEAR 1 MONITORING REPORT - 2017, YEAR 1 OF 5 of pebble count data collected indicated that stream is sufficiently moving fines through the system. Riffles are comprised of a mix of substrates with the bed material moving towards a mix of coarser substrates. Cross- sectional and pebble count data are provided in Figures 3 and 4, respectively, in Appendix D. In -stream pressure transducers, TC FL and TC FL2, were installed on Reach 1 to document intermittent flow conditions throughout the monitoring year. Since post -construction installation, each gauge has documented at least one period of consecutive stream flow for the required minimum of 30 days, with a maximum of 168 consecutive days for TC FL and 150 consecutive days for TC FL2. Figures 5a and 5b in Appendix E, depict the documented flow conditions for each gauge from installation through Monitoring Year 1 relative to local rainfall data, while Table 13 documents both the total cumulative days of flow and the maximum number of consecutives days of flow. Lastly at least one post -construction bankfull event occurred during MYL Documentation of the event was recorded on 10/12/2016 and is located in Table 12 in Appendix E. Summary information/data related to the Site and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report Appendices. Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report and in the Mitigation Plan available on the NCDMS' website. All raw data supporting the tables and figures in the appendices is available from NCDMS upon request. 2.0 METHODOLOGY The five-year monitoring plan for the Site includes criteria to evaluate the success of the stream and vegetation components of the project. Monitoring methods used will follow the NCDMS Monitoring Report Template, Version 1.3 — 1/15/10 and are based on the design approaches and overall project goals. To evaluate success criteria associated with a geomorphically stable channel, hydrologic connectivity, and aquatic habitat diversity, geomorphic monitoring methods will be conducted for project reaches that involve Restoration and Enhancement Level I mitigation. The specific locations of monitoring features, such as vegetation plots, permanent cross-sections, reference photograph stations and crest gauges, are shown on the CCPV sheets found in Figure 2 of Appendix B. Year 1 monitoring data were collected in October and November 2016. All visual site assessment data contained in Appendix B were collected on October 12, 2016. Vegetation data and plot photos were collected on November 10 and 12, 2016, respectively. Sediment data were collected on October 11 and 12, 2016. Stream survey data were collected on November 3' and certified on November 9' of 2016. Stream survey data were collected to meet the requirements for a topographic ground survey to the accuracy of Class C Vertical and Class A Horizontal (21 NCAC-56 section .1606) and was geo-referenced to the NAD83 State Plane Coordinate System, FIPS3200 in US Survey Feet, which was derived from the Town Creek Restoration Project Option B's As -built Survey. 2.1 Stream Monitoring Geomorphic monitoring of the Restoration and Enhancement Level I reaches will be conducted once a year for a minimum of five years following the completion of construction. These activities will evaluate the success criteria associated with a geomorphically stable channel, hydrologic connectivity, and aquatic habitat diversity. The stream parameters to be monitored include stream dimension (cross-sections), pattern (planimetric survey), profile (longitudinal profile survey), visual observation with photographic documentation, and documentation of bank full events. Additionally, monitoring methods for all reaches will include those described under Photo Documentation of Site, Visual Assessment, and Vegetation Monitoring. The methods used and related success criteria are described below for each parameter. Figure 2 shows approximate locations of the proposed monitoring devices throughout the project site. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 95026 TOWN CREEK RESTORATION PROJECT - OPTION B YEAR 1 MONITORING REPORT - 2017, YEAR 1 OF 5 2.1.1 Morphologic Parameters and Channel Stability 2.1.1.1 Dimension A total of thirteen (13) permanent cross-sections, nine (9) riffles and four (4) pools, were installed throughout the entire project area. Cross-sections selected for monitoring included representative riffle and pool facets for each of the three project reaches, Reach 2, 3, and 5, which implemented at least 500 linear feet of Restoration or Enhancement I activities. Each cross-section was marked on both banks with permanent pins to establish the exact transect used. A common benchmark was also chosen to consistently reference and facilitate the comparison of year- to-year data. The cross-sectional surveys are conducted annually and include measurements of Bank Height Ratio (BHR) and Entrenchment Ratio (ER). The monitoring survey includes points measured at all breaks in slope, including top of stream banks, bankfull, inner berm, edge of water, and thalweg, if the features are present. Riffle cross-sections are classified using the Rosgen Stream Classification System (Rosgen, 1994), and all monitored cross-sections should fall within the quantitative parameters defined for channels of the design stream type. There should be little change in annual cross-sectional surveys from those collected during the post - construction as -built survey. If changes do take place, they will be evaluated to determine if they represent a movement toward a more unstable condition (e.g., down -cutting or erosion) or a movement toward increased stability (e.g., settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross-sectional data is presented in Figure 3 of Appendix D. 2.1.1.2 Longitudinal Profile A longitudinal profile was surveyed for the entire length of channel immediately after construction to document as -built baseline conditions for the first year of monitoring only. The survey was tied to a permanent benchmark and measurements included thalweg, water surface, bankfull, and top of low bank. Each of these measurements was taken at the head of each feature (e.g., riffle, pool) and at the maximum pool depth. Yearly longitudinal profiles will not be conducted during subsequent monitoring years unless channel instability has been documented or remedial actions/repairs are required by the USACE or NCDMS. 2.1.1.3 Substrate and Sediment Transport After construction, there should be minimal change in the pebble count data over time given the current watershed conditions and sediment supply regime. A substrate sample was collected for each riffle cross-sections where constructed riffles were installed (X1, X4, X5, X7, X9, X10, and X12). Samples collected combined with evidence provided by changes in cross-sectional data and visual assessments will reveal changes in sediment gradation that occur over time as the stream adjusts to upstream sediment loads. Significant changes in sediment gradation were evaluated with respect to stream stability and watershed changes. Bed material distribution data are located in Figure 4 of Appendix D. 2.1.2 Stream Hydrology 2.1.2.1 Bankfull Events The occurrence of bankfull events within the monitoring period were documented by the use of a crest gauge and photographs. The crest gauge will record the highest watermark between site visits, and the gauge will be checked at each site visit to determine if a bankfull event has occurred. The crest gauge was installed the floodplain of Reach 5 within ten feet (horizontal) of the restored channel. Photographs will be used to document the occurrence of debris lines and sediment deposition on the floodplain during monitoring site visits. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 95026 TOWN CREEK RESTORATION PROJECT - OPTION B YEAR 1 MONITORING REPORT - 2017, YEAR 1 OF 5 Two bankfull flow events must be documented within a five-year monitoring period. The two bankfull events must occur in separate years; otherwise, the monitoring will continue until two bankf ill events have been documented in separate years to demonstrate a floodplain connection has been restored. 2.1.2.2 Flow Documentation A combination of photographic and flow gauge data were collected from two in -stream pressure transducers (TC FL 1 and TC FL2) and a remote in -field camera that were installed on Reach 1. Collected data will document that the restored intermittent stream system continues to exhibit base flow for of at least 30 consecutive days throughout each monitoring year under normal climatic conditions. In order to determine if rainfall amounts were normal for the given year, rainfall gauge data was obtained from the nearest Stanly County weather station (CRONOS Database, NEWL — North Stanly Middle School, if available) and compared to the average monthly rainfall amounts from the Stanly County WETS Table (USDA, 2016). If a normal year of precipitation does not occur during the first five years of monitoring, flow conditions will continue to be monitored on the site until it documents that the intermittent streams have been flowing during the appropriate times of the year. Flow data and photographic documentation collected during Year 1 monitoring are located in Appendix E. 2.1.3 Photographic Documentation of Site Photographs were used to document restoration success visually. Reference stations and cross-section photos were photographed during the as -built survey; this will be repeated for at least five years following construction. Reference photos were taken once a year, from a height of approximately five to six feet. Permanent markers ensure that the same locations (and view directions) are utilized during each monitoring period. Photographers will make an effort to consistently maintain the same area in each photo over time. Selected site photographs are shown in Appendix B for reference stations and Appendix D for cross-sections. 2.1.3.1 Lateral Reference Photos Reference photo transects were taken of the right and left banks at each permanent cross-section. A survey tape was captured in most photographs which represents the cross-section line located perpendicular to the channel flow. The water line was located in the lower edge of the frame in order to document bank and riparian conditions. 2.1.3.2 Longitudinal Station Photos Stream reaches were photographed longitudinally beginning at the upstream portion of the Site and moving downstream. Photographs were taken looking both upstream and downstream at delineated locations throughout the restored stream valley. The photograph points were established close enough together to provide an overall view of the reach lengths, primary grade control structures, and valley crenulations. The angle of the photo depends on what angle provides the best view was noted and will be continued in future photos. Site photographs are located in Appendix B. 2.1.4 Visual Assessment Visual monitoring assessments of all stream sections will be conducted by qualified personnel twice per monitoring year with at least five months in between each site visit. Photographs will be used to document system performance and any areas of concern related to stream bank stability, condition of in -stream structures, channel migration, aggradation/degradation, headcuts, live stake mortality, impacts from invasive plant species or animal species, floodplain vegetative conditions, and condition of pools and riffles. The photo locations will be shown on a plan view map and descriptions will be documented in as either stream problem areas (SPAS) or vegetative problem areas (VPAs) in there associated monitoring assessment tables located in Appendix B. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 95026 TOWN CREEK RESTORATION PROJECT - OPTION B YEAR 1 MONITORING REPORT - 2017, YEAR 1 OF 5 2.2 Vegetation Monitoring In order to determine if the criteria are achieved, vegetation -monitoring quadrants were installed and are monitored across the restoration site in accordance with the CVS-NCEEP Protocol for Recording Vegetation, Version 4.0 (2006). The vegetation monitoring plots are a minimum of 2 percent of the planted portion of the site with eight plots established randomly within the planted riparian buffer areas. No monitoring quadrants were established within the undisturbed wooded areas of the project area. The size of individual quadrants are 100 square meters for woody tree species. Level 1 CVS vegetation monitoring was conducted between spring, after leaf -out has occurred, and fall prior to leaf fall. Individual quadrant data provided during subsequent monitoring events will include species composition, density, survival, and stem height. Relative values were calculated, and importance values were determined. Individual seedlings were marked to ensure that they can be found in succeeding monitoring years. Mortality was determined from the difference between the previous year's living, planted seedlings and the current year's living, planted seedlings. The interim measure of vegetative success for the site is the survival of at least 320, 3 -year old, planted trees per acre at the end of Year 3 of the monitoring period. The final vegetative success criteria is the survival of 260, 5 -year old, planted trees per acre at the end of Year 5 of the monitoring period. Photographs were used to visually document vegetation success in sample plots and are located in Appendix C.
