(Baker) through an on-call design and construction services contract with the North Carolina Division of Mitigation Services (NCDMS). This report documents and presents Year 5 monitoring data as required during the five-year monitoring period. The specific goals for the Project were as follows: Create geomorphically stable conditions on the Project site, Improve and restore hydrologic connections between the streams and their floodplains, Improve water quality in the South Fork Hoppers Creek watershed, Protect the South Fork Hoppers Creek watershed from nearby rapid development, Restore wetlands along South Fork Hoppers Creek in the Project area, and Improve aquatic and terrestrial habitat along the Project corridor. To accomplish these goals the following objectives were implemented: Stabilize eroding channel banks by implementing a combination of Priority I Restoration and Enhancement II approaches, Increase floodplain connectivity to restore historic floodplain wetlands, Incorporate bedform diversity with varied in -stream structures to provide a variety of aquatic habitats, Reestablish a riparian buffer with native vegetation to improve terrestrial habitat and eliminate excessive sedimentation from erosion, Restore and enhance existing floodplain wetlands, where feasible, and Eliminate livestock access to the channel to improve water quality and reduce erosion from hoof shear. The Project site is located approximately 10 miles southeast of Marion in McDowell County, North Carolina, as shown in Figure 1 in Appendix A. The Project is situated in the Catawba River Basin, within the United States Geologic Survey (USGS) hydrologic unit 03050101040-020. Directions to the Project site can be found in Figure 1 of Appendix A. South Fork Hoppers Creek lies within the Piedmont physiographic province. Its watershed is predominately forested, supporting some isolated rural residential housing, chicken farms, agricultural lands, nurseries, and several small rural residential developments. The land surrounding the Project site has been used historically for agriculture but was recently used as pasture land for livestock grazing. Some forest land is located in the upstream extents of UTI, UT2, and UT3. South Fork Hoppers Creek and its tributaries had been impacted by livestock, were incised, and eroded. Channel incision along South Fork Hoppers Creek resulted in the lowering of the water table; thereby, dewatering floodplain wetlands. The Project involved the restoration or enhancement of 3,550 linear feet (LF) of stream along South Fork Hoppers Creek, and portions of UTI and UT2 using Rosgen Priority I restoration and Level 11 enhancement approaches. An additional 1,071 LF of stream along portions of UTI and UT3 was placed in preservation. The Project also included the restoration and enhancement of 1.56 acres of riparian wetland abutting South Fork Hoppers Creek and UTI of which 1.23 acres comprised restoration and 0.33 acres comprised enhancement. The Priority I channel design approach entailed raising the elevation of the channel to establish greater connectivity to the floodplain and to restore the hydrologic relationship between South Fork MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 5 MONITORING REPORT - JANUARY 2017 MONITORING YEAR 5 OF 5 Hoppers Creek, its tributaries and riparian wetland areas in the Project area. Channel pattern was re-established to dissipate flow velocities in meander bends. In -stream habitat was created using riffle -pool sequences and the strategic placement of in -stream structures. Approximately 5.7 acres of associated riparian buffer were restored/enhanced throughout the Project area and a conservation easement consisting of 10.1 acres will protect and preserve all stream reaches, wetland areas, and riparian buffers in perpetuity. Vegetation conditions for South Fork Hoppers Reaches 1 and 2, and UTIReach B, and UT2 Reaches A and B were good and performing close to 100% for both the planted acreage and invasive/encroachment area categories. Treatment control applications for exotic invasive species were conducted in monitoring Years 2 and 4; however, three Vegetation Problem Areas (VPAs), consisting predominantly of Lonicera japonica (Japanese honeysuckle) and Rosa multiflora (multi -flora rose) and exceeding the mapping threshold continue to persist. A more detailed summary of the results for the vegetation condition assessment can be found in Appendix B which includes a technical memorandum, current condition plan view (CCPV) figures, supporting data tables, and photo logs. The contents of Appendix B were submitted to NCDMS in May 2016 and served as the interim visual site assessment report. The average density of total planted stems per plot ranges from 324 — 890 stems per acre with a tract mean (not including volunteers) of 587 stems per acre; therefore the Site has met the Year 5 vegetative success criteria of 260 trees per acre. Volunteer species continue to thrive throughout the vegetation plots and include planted species, as well as, other native species such as: Pinus virginiana and Rubus sp. Vegetation stem counts are summarized in Tables 7 and 9 of Appendix C. Tables 5a through 5d (Appendix B) indicate the Project site has remained geomorphically stable overall, with lateral/vertical stability and in -stream structure performance of 100% on UT1B, 83 — 100% on Reach 1, 95 — 100% on Reach 2, and 60 —100% on UT2 A and B. The sub -categories receiving scores of less than 100% are namely due to small localized areas of bank scour and/or erosion around structures. Stream Problem Areas (SPAS) correlating with these areas of instability for the project reaches are documented and summarized in Table 5e of Appendix B. A more detailed summary of the results for the visual stream stability assessment can be found in the "Site Assessment Report — Monitoring Year 5" in Appendix B. The six permanent cross-sections along the Project site show that there has been little adjustment to stream dimension overall within the Project site since construction. Cross-section 9 (X9) exhibits only a minor amount sedimentation in the riffle, which is most likely a result, as indicated from the sediment analysis, of an influx of sands from the upstream ford crossing. As indicated in Figure 3, cross-sectional measurements throughout the five year monitoring period have remained geomorphically similar to as -built conditions and do not indicate any stream bank or channel stability issues. The longitudinal profiles show that bed features are stable. Pools are well maintained with only minor filling in the upstream sections of Reach 1 and UT1B, which is most likely due to the natural movement of sediment through the system in areas where the channel gradient is low and the floodplain remains inundated throughout much of the year. Grade control structures (constructed riffles, cross vanes and log sills) continue to help maintain the overall profile desired. As depicted in Figure 4, overall longitudinal profiles for Reach 1, 2, and UT1B have remained geomorphically stable throughout the post -construction five year monitoring period. Visual observations and a review of pebble count data collected during Year 5 monitoring did not yield any signs that sediment transport functions have been hampered by the mitigation project. The pebble count data for South Fork Hoppers Creek and UT 1B indicate that the stream is moving fines through the system and a mix of substrates make up the bed material. Pebble count data is provided in Figures 5a — 5c in Appendix D. Two bankfull event were observed and documented during MY5. Overall the site has experienced at least seven documented bankfull events during the five year monitoring period. With at least two of the events occurring in separated monitoring years, the site has met its hydrologic success criteria. Information on bankfull events is provided in Table 12 of Appendix E. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 5 MONITORING REPORT - JANUARY 2017 MONITORING YEAR 5 OF 5 Though groundwater data loggers for Wells 2 and 4 had to be replaced in August 2016, all four wetland areas met the success criteria for wetland hydrology during Monitoring Year 5. Groundwater conditions indicated saturated conditions existed throughout 100% of the growing season for Gauge 3 and for Gauges 2 and 4, after replacement, while Gauge 1 documented saturated conditions for 99.5% of the growing season. Based on ground water data collected during the five growing seasons following site construction (March 30, 2013 - November 2, 2016), the site has successfully met the success criteria for wetland hydrology of soil saturation within 12 inches of the soil surface for at least 9% of the growing season, or 19 consecutive days. See Appendix E for a depiction of plot of wetland gauge data as it relates to monthly precipitation for Monitoring Year 5 (Figure 7) and a summary of wetland gauge attainment for all five monitoring years (Table 13). See CCPV sheets (Figure 2) in Appendix B, for a depiction of wetland and corresponding gauge locations. Summary information/data related to the occurrence of items such as beaver or encroachment, 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 (formerly Mitigation Plan) and in the Mitigation Plan (formerly Restoration Plan) documents available on DMS's website. It should be noted that the Baseline Monitoring Report and Mitigation Plan for this Project site is included with the summary of constructed design approaches for the South Muddy Creek Restoration Project (DMS Project No. 737), a nearby project site that was designed and constructed in conjunction with the Hoppers Creek - Melton Farm Stream Restoration Project as part of the same DMS on-call design and construction services contract. All raw data supporting the tables and figures in the appendices is available from DMS upon request. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 5 MONITORING REPORT - JANUARY 2017 MONITORING YEAR 5 OF 5 2.0 METHODOLOGY The five-year monitoring plan for the Project site includes criteria to evaluate the success of the vegetation, stream, and wetland components of the project. The methodology and report template used to evaluate these three components adheres to the DMS monitoring guidance document dated November 7, 2011, which will continue to serve as the template for subsequent monitoring years. The specific locations of monitoring features, such as vegetation plots, permanent cross-sections, reference photo stations and wetland/crest gauges, are shown on the CCPV sheets found in Figure 2 of Appendix B. The majority of Year 5 monitoring data was collected in May 2016 and October 2016. All visual site assessment data was collected on May 25, 2016. Vegetation monitoring plot and sediment data were collected between October 18' and 19th, 2016. All stream survey (channel dimension and profile) data were collected between September 27' and October 4th, 2016. Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using Leica TS06 Total Station and was geo-referenced to the NAD83 State Plane Coordinate System, FIPS3200 in US Survey Feet, which was derived from the South Fork Hoppers Creek As - built Survey. 2.1 Stream Assessment Geomorphic monitoring of restored stream reaches was conducted for five years to evaluate the effectiveness of the restoration practices installed. Monitored stream parameters include channel dimension (cross-sections), profile (longitudinal survey), bed composition, bank and channel stability, bankfull flows, and reference sites documented by photographs. A crest gauge, as well as high flow marks, were used to document the occurrence of bankfull events. The methods used and any related success criteria are described below for each parameter. For monitoring stream success criteria, 6 permanent cross-sections, 1 crest gauge, and 39 photo identification points were installed. 2.1.1 Morphologic Parameters and Channel Stability 2.1.1.1 Dimension Six permanent cross-sections were installed throughout the entire project area. Cross-sections selected for monitoring were located in representative riffle and pool facets and each cross-section was marked on both banks with permanent pins to establish the exact transect used. Each of the three restored Project reaches, Reaches 1 and 2 of South Fork Hoppers Creek and UTIB, contains one riffle and one pool cross-section. A common benchmark is being used for cross-sections and consistently referenced to facilitate comparison of year-to-year data. The cross-sectional surveys included points measured at major breaks in slope, including top of bank, bankfull, inner berm, edge of water, and thalweg, if the features are present. Riffle cross-sections were 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 as -built cross-sections. 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 Longitudinal profiles were surveyed for the entire restored lengths of Reaches 1 and 2 of South Fork Hoppers Creek and UT1B, and are provided in Figure 4 of Appendix D. Longitudinal profiles were replicated annually during the five year monitoring period. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 5 MONITORING REPORT - JANUARY 2017 MONITORING YEAR 5 OF 5 Measurements taken during longitudinal profiles include thalweg, water surface, and the top of low bank. All measurements were taken at the head of each feature (e.g., riffle, run, pool, glide) and the maximum pool depth. Elevations of grade control structures were also included in the longitudinal profiles surveyed. Surveys were tied to a permanent benchmark. The pools should remain relatively deep with flat water surface slopes, and the riffles should remain steeper and shallower than the pools. Bed form observations should be consistent with those observed for channels of the design stream type as well as other design information. 2.1.1.3 Substrate and Sediment Transport Bed load material analysis consists of a pebble count taken in the same constructed riffle during annual geomorphic surveys of the Project site. One sample was collected at the riffle cross-section corresponding with each of the three restored Project reaches for a total of three sediment samples (cross-sections X5, X7, X9). These samples, combined with evidence provided by changes in cross- section and profile data 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 5 of Appendix D. 2.1.2 Hydrology 2.1.2.1 Streams The occurrence of bankfull events within the monitoring period were documented by the use of crest gauges and photographs. One crest gauge was installed on the floodplain at the bankfull elevation along the right top of bank at station 15+10. The bottom of the crest gauge coincides with the top of bank (bankfull) elevation. The crest gauges record the highest watermark between site visits, and are checked at each site visit to determine if a bankfull event has occurred. Photographs are used to document the occurrence of debris lines and sediment deposition on the floodplain during monitoring site visits. Two bankfull flow events must be documented at the crest gauge within the 5 -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 or until the monitoring period ends. If two bankfull events have not been documented at the end of 5 years the Interagency Review Team (IRT) will have to decide on an appropriate course of action. 2.1.3 Photographic Documentation of Site Photographs were used to document restoration success visually. Reference stations 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. Selected site photographs are shown in Appendix B. 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. Photographers will make an effort to consistently maintain the same area in each photo over time. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 5 MONITORING REPORT - JANUARY 2017 MONITORING YEAR 5 OF 5 2.1.3.2 Structure Photos Photographs of primary grade control structures (i.e. vanes and weirs), along the restored streams are included within the photographs taken at reference photo stations. Photographers have made every effort to consistently maintain the same area in each photo over time. Lateral and structure photographs were used to evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, structure function, and stability, and effectiveness of erosion control measures subjectively. Lateral photos should not indicate excessive erosion or degradation of the banks. A series of photos over time should indicate successive maturation of riparian vegetation and consistent structure function. 2.1.4 Visual Stream Morphological Stability Assessment The visual stream morphological stability assessment involves the qualitative evaluation of lateral and vertical channel stability, and the integrity and overall performance of in -stream structures throughout the Project reach as a whole. Habitat parameters, such as riffle embeddedness and pool depth maintenance, were also measured and scored. The entire project reach was walked, noting geomorphic conditions of the stream bed profile (riffle/pool facets), both stream banks, and engineered in -stream structures. Photos were taken at every stream photo reference station as discussed in the previous section, and in locations of potential SPAS which were documented in the field for subsequent mapping on the CCPV figures. A more detailed summary of the methodology and results for the visual stream stability assessment can be found in Appendix B which includes a technical memorandum, supporting data tables, and SPA photos. 2.2 Vegetation Assessment Successful restoration of the vegetation on a mitigation site is dependent upon hydrologic restoration, active planting of preferred canopy species, and volunteer regeneration of the native plant community. In order to determine if the criteria are achieved, twelve vegetation monitoring quadrants were installed across the Project site, which included one wetland vegetation plot. The total number of quadrants was calculated using the CVS- NCEEP Entry Tool Database version 2.3.1 (CVS-NCEEP, 2012). The size of individual quadrants for tree species is 100 -square meters. Level 1 CVS vegetation monitoring was conducted between spring, after leaf - out has occurred, and fall prior to leaf fall. At the end of the first growing season during baseline surveys, species composition, density, and survival were evaluated. Individual quadrant data provided during subsequent monitoring events will include diameter, height, density, and coverage quantities. 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. Reference photos of vegetation condition within plots were taken at least once per year. As part of the visual site assessment conducted on May 25, 2016, the vegetation condition of planted vegetation along stream banks, floodplains (wetlands), and terraces were qualitatively evaluated for performance. This assessment also included the documentation of invasive species and potential VPAs, which were recorded in the field for subsequent mapping on the CCPV figures. A more detailed summary of the methodology and results for the vegetation condition assessment can be found in Appendix B which includes a technical memorandum, supporting data tables, and photo logs. 2.3 Wetland Assessment Four groundwater monitoring stations were installed in restored/enhanced wetland areas to document hydrologic conditions at the Project site. These four wetland gauges are depicted on the CCPV figures found MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 5 MONITORING REPORT - JANUARY 2017 MONITORING YEAR 5 OF 5 in Appendix B. Installation and monitoring of the groundwater stations have been conducted in accordance with the USACE standard methods outlined in WRP Technical Notes ERDC TN -WRAP -00-02 (July 2000). Precipitation data from a nearby U.S. Geological Survey rain gauge near Morganton, NC (USGS 354353081410545) was used for comparison to post -construction groundwater monitoring conducted during the Year 4 growing season. This data was obtained from the USGS "waterdata" website (USGS 2016). Baker used DRAINMOD (Version 5.1) to develop hydrologic simulation models that represented conditions at a variety of locations across the Project site. DRAINMOD indicated wetland hydrology would occur for approximately 6-12% of the growing season. Based on these findings, it was determined that success criteria for wetland hydrology will be met when each wetland site is saturated within 12 inches of the soil surface for at least 9% of the growing season, or 19 consecutive days.

Hoppers Creek — Melton Farm Stream Restoration Project NCDEQ — DMS (Prof. No. 9225 1) May 2016 Page 1 of 7 I Introduction 1.1 Purpose This report summarizes overall stream and vegetation conditions as part of an interim site assessment conducted in conjunction with the Year 5 monitoring services for the Hoppers Creek - Melton Farm Stream Restoration Project site located in McDowell County, NC. This site assessment will be included as part of a more comprehensive Annual Monitoring Report to be completed and submitted later this year (Fall 2016). The report describes project objectives, discusses the assessment methodology, summarizes assessment results, and documents potential stream and vegetation problem areas (SPAS and VPAs respectively). 1.2 Objectives The objectives of the site assessment were to: Provide a general overview of stream morphological stability; Provide a general overview of vegetation conditions; Identify and document potential SPAS and VPAs. 1.3 Supporting Data Supporting data and information are provided following the narrative portion of this report and include: Current condition plan view (CCPV) figures (Figure 2, sheets 1 through 3); Visual stream morphology stability assessment table (Tables 5a through 5d); SPA inventory table (Table 5e); Vegetation condition assessment table (Tables 6a and 6b); VPA inventory table (Table 6c); Stream station photos; SPA photos; VPA photos. 2 Methodology The methodology used for assessing overall stream and vegetation conditions at the Hoppers Creek - Melton Farm Stream Restoration Project site adhered to the NCDEQ DMS monitoring guidance documents (dated November 7, 2011). The site assessment was comprised of two components, a visual stream morphology stability assessment and a vegetation condition assessment, both of which are described in more detail in the following sections of this report. The assessment was strictly qualitative. Vegetation monitoring plot counts were excluded from this assessment but will be conducted after July 2015. This data will be summarized in Appendix C and the CCPV figure of the Year 5 Annual Monitoring Report to be submitted in late November of this year. Year 5 Site Assessment Report - Michael Baker Engineering, Inc. Hoppers Creek — Melton Farm Stream Restoration Project NCDEQ — DMS (Prof. No. 9225 1) May 2016 Page 2 of 7 The Hoppers Creek -Melton Farm Stream Restoration Project site was evaluated as four separate project reaches for the visual stream morphology stability assessment as they were for the Final Baseline Monitoring Document/As-Built Report: South Fork Hoppers Creek (SFHC) Reaches 1 and 2, UTI Reach B, and UT2 (Reaches A and B). SFHC Reaches 1 and 2 are delineated by the confluence of UT 1 Reach B where SFHC Reach 1 is located upstream of the confluence and SFHC Reach 2 is located downstream of the confluence. UT2 Reach A extends from the upstream limits located within the conservation easement boundary to the downstream limits of the constructed step -pool channel, and UT2 Reach B includes the remaining corridor located downstream of the step -pool channel until its confluence with SFHC Reach 1. 2.1 Visual Stream Morphology Stability Assessment The visual stream morphology stability assessment involved the evaluation of lateral and vertical channel stability, and the integrity and overall performance of in -stream structures throughout each of the four project stream reaches. Habitat parameters, such as riffle embeddedness and pool depth maintenance, were also measured and scored. Each stream reach was walked, noting geomorphic conditions of the stream bed profile (riffle/pool facets), both stream banks, and engineered in - stream structures. Photos were taken at every existing stream photo point (from the as -built) and in locations of potential SPAS which were recorded in the field for subsequent mapping on the CCPV figures. 2.2 Vegetation Condition Assessment The vegetation condition assessment involved the evaluation of vegetation within the 10.1 acre conservation easement and included assessing the performance of planted vegetation along stream banks, floodplains, and terraces as well as the documentation of invasive species. The assessment of planted vegetation was confined to the 5.7 acres of riparian buffer planting zones located within the easement boundary as part of the restoration design; whereas, invasive vegetation and encroachment areas of invasive species were evaluated for the entire 10.1 acre easement boundary. Photos were recorded in locations of potential VPAs throughout the easement, such as areas exhibiting sparse or slow growth/vigor, low stem density, and invasive areas of concern. 2.3 Post -processing of Field Data The post -processing of field data consisted of the download and organization of photos into respective photo logs (stream and vegetation), creating the CCPV figures in GIS using the field - mapped SPAS and VPAs, populating the SPA and VPA tables, and finally scoring the performance of the four stream reaches and two vegetation tracts in terms of stream morphological stability and vegetation condition using assessment forms provided by NCDEQ DMS. 3 Summary of Results 3.1 Visual Stream Morphology Stability Assessment Tables 5a through 5d summarize the performance of each of the four project stream reaches mentioned above for the Hoppers Creek -Melton Farm Stream Restoration Project in terms of lateral (stream bank) and vertical (channel bed) stability while evaluating the functionality and integrity of in -stream structures. Engineered in -stream structures evaluated for the assessment of this project reach consisted of constructed riffles, log sills (drops), cross vanes, log vanes, root wads, geo-lifts, and brush mattresses. Constructed riffles were justified for inclusion in the evaluation of structures since they are the predominant grade control structure used throughout the site; however, they were Year 5 Site Assessment Report - Michael Baker Engineering, Inc. Hoppers Creek — Melton Farm Stream Restoration Project NCDEQ — DMS (Prof. No. 9225 1) May 2016 Page 3 of 7 only assessed for the `overall integrity' and `grade control' parameter categories in Tables 5a through 5d. As Tables 5a through 5d indicate, the Hoppers Creek -Melton Farm Stream Restoration Project site was geomorphically stable overall and performing at or near 100 percent as the design intended for the majority of parameters evaluated within the lateral/vertical stability and in -stream structure performance categories. UTI Reach B was functioning at the highest level geomorphically out of all the stream project reaches, performing at 100 percent for all morphological sub -categories. Individual results for the remaining reaches varied in performance for the three major morphological channel categories. Both SFHC Reach 1 and Reach 2 performed at 100% for bedform condition and stability and at 96% for bank stability; however, they differed slightly relative to performance of engineered structures. SFHC Reach 1 received scores ranging from 91% to 100% for the performance of engineered structures, while SFHC Reach 2 received ranging from 95% to 100%. Performance rates of less than 100% on these reaches were due primarily due to erosional pockets forming around root wad and log sill bank tie-ins. UT2 performed near 100% for the majority of the sub -category metrics. Pool performance for two out of the five step pools received more moderated ratings in the categories of condition and habitat. Though the results seem unfavorable, they are likely only the result of the natural processes of moving sediment loads from large storm events through the system and not a performance issue. This is especially likely since these results were not noted as occurring or trending in previous assessment years. SPAS correlating with these issues for these three project reaches were documented and summarized in Table 5e. There were a total of thirteen SPAs documented, three of which were identified during the Year 1 visual assessment, one that was identified during the Year 2 assessment, three that were identified during the Year 4 assessment, and six that were identified during the Year 5 assessment. SPAs documented in previous years were included in this assessment since they have persisted to date. Any SPA's that have been documented in previous reports, but were not indicated as problems during the Year 5 assessment will not be described. The first number in the SPA naming convention (in Table 5e) references the monitoring year in which the SPA was identified during the visual assessment. A brief description of the SPAs reported from this year and persisting from previous years is discussed below. The SPAs from previous years noted in this report have generally remained unchanged in condition and scale when observed during this assessment, but they still remain problem areas and should be monitored. All are included in the scoring of morphological performance categories in Tables 5a through 5d, and are also summarized in Table 5e, Figure 2 (CCPV), and the SPA photolog. SPA 1-2 is characterized by a localized area of bank scour along the right bank of Reach 1 of SFHC. This SPA is likely caused by the invert of the upstream log roller directing the channel flow toward the bank just downstream of sill tie-in. The bank slope in this area is vertical; however, it is well vegetated at the top of bank. The area may widen slightly, but should stabilize in time as the large woody vegetation becomes even more established in this area. SPA 1-5 consists of the piping of flow around a log sill structure in UT2 Reach A. The structure is vertically and laterally stable and should seal over time. The heavily armored, ephemeral drainage located near the upstream extents of UT2 Reach A was inspected for overall structural integrity and stability even though the short reach is not being sought Year 5 Site Assessment Report - Michael Baker Engineering, Inc. Hoppers Creek — Melton Farm Stream Restoration Project NCDEQ — DMS (Prof. No. 9225 1) May 2016 Page 4 of 7 for mitigation credit. Upon inspection, the channel bed of the downstream riffle cascade has eroded (SPA1-6) and a small localized area of erosion persists on the right upper bank. Coarse riprap material has been deposited downstream atop the lowest elevation boulder sill, exposing the underlying filter fabric as a result. SPA2-1 and SPA5-3 are located just downstream of a log sill on SFHC Reach 1 at Station 16+25. These SPAs are characterized by erosion, undercut bank, and structure failure. The invert along the upstream log sill is directing velocity vectors into the bank which has caused erosion to occur around the back of the root wad and the invert/left bank tie-in of the downstream log sill; therefore, resulting in structure failure. The root wad has slumped into the channel and the log sill had separated ftom the bank and is under water. Native herbaceous and woody vegetation are present and providing some stability to the bank. This area will be assessed again during the Year 5 Monitoring period to document its state of stability. SPA4-1 and SPA 5-5 are located on the left bank just downstream of a log sill on SFHC Reach 2 at Station 20+20. These SPAs are characterized by erosion, undercut bank, and structure failure. The invert along the upstream log sill is directing velocity vectors into the bank causing erosion to occur around the back of the root wad and around the downstream of log sill invert/left bank tie-in. The root wad and the sill's header log are still tied -in to the bank; however, it appears that the sill's header and footer have separated. Currently the header log is suspended across the channel above the surface water elevation. Native herbaceous and woody vegetation are present and aiding in the stability of the bank. This area will be assessed again during the Year 5 Monitoring period to document its state of stability. SPA4-2 consists of both bank erosion and undercut bank and is located along the right bank downstream of a log sill on SFHC Reach 2 (Station 20+75). This SPA is likely caused by the invert of the log sill directing the channel flow into the right bank just downstream of sill's tie-in. The area of erosion is located immediately upstream of the root wad and may eventually compromise the integrity of the structure. However, the root wad is still providing some bank protection, at this time. Native herbaceous and woody vegetation are present and are providing some stability to the bank. This area will be assessed again during the Year 5 Monitoring period to document its state stability. SPA4-3 is located on UT2 Reach A between Stations 12+36 to 12+53. In this area, the channel hugs the valley wall, and the outside meander bend experiences high levels of near bank stress during bankfull events which has led to a localized area of bank scour. SPA5-1 and SPA5-2 are located on UT 2 Reach A just below the second and fourth log step, respectively. These SPAs consist of sediment filled pools. Because it is normal for an active channel to move sediment through the system and there are no other indicators of excessive aggradation within this area, it is likely that this is just part of the normal channel processes. These SPAs will be reassessed during the Year 5 monitoring period. SPA 5-4 is located on Reach 1 of SFHC from Station 18+30 to 18+45. The SPA consists of a localized area of erosion on the left in between the rootwads along the apex of the meander bend. Both woody and herbaceous vegetation are still present and aiding the stability of the bank. This area is likely to heal over time. SPA 5-6 is located on Reach 2 of SFHC at Station 20+45. The SPA consists of undercutting of the right bank between root wads immediately downstream of the compromised log sill associated with SPA5-5. This appears to be a localized area of erosion caused by high levels of near bank stresses Year 5 Site Assessment Report - Michael Baker Engineering, Inc. Hoppers Creek — Melton Farm Stream Restoration Project NCDEQ — DMS (Prof. No. 9225 1) May 2016 Page 5 of 7 directed at the right bank and currently it is unclear whether or not this SPA is a result of the upstream problem area. This area will be further monitored during the Year 5 monitoring period. Log sills associated with deep scour pools on UTI Reach B between Stations 19+00 and 19+50 were inspected and assessed for vertical stability per DMS' request during the Year 2 assessment and reassessed during the Year 4 assessments. DMS' concern was that the depth of some of the scour pools on a channel with such a small dimension could potentially pose a threat and undermine the integrity of its upstream log step. During these assessments pool depth and pool to pool ratio were evaluated and compared to the design values. The upstream log sill was the deepest of the three located within the assessment area and had a dpool value and dpoo,/dbkf ratio of 2.8 feet and 5.2 respectively. These measurements are greater than design values and had slightly increased from the previous assessment; however, they still meet DMS' monitoring guidance criteria for the assessment. Additionally, this log sill structure was evaluated for stability. Because each sill is constructed with both a header and footer log, the footer log on this log sill was still buried below the elevation of the scour pool, affording protection from undermining and helping to hold the entire structure firmly in place. Therefore, since the channel bed is stable and it is normal for pool depths and pool to pool ratios to fluctuate over time in an active riparian systems. Observations of this area during the Year 5 assessment did not document any instability; therefore, no measurements were taken. These log sills/scour pools will also be assessed during the Year 5 monitoring period. 3.2 Vegetation Condition Assessment Tables 6a and 6b summarize the vegetation conditions of the Hoppers Creek -Melton Farm Stream Restoration site. Table 6a references the vegetation assessment tract associated with SFHC Reaches 1 and 2, and UTI Reach B; Table 6b references the vegetation assessment tract associated with UT2 (Reaches A and B). There were a total of three mapped VPAs. All of which consist of the presence of an invasive species population at least 1000 square feet in size. One of the three was identified during the Year 2, while the remaining two were identified during the Year 4 assessment. The presence of invasive species accounts for all three of the VPAs. A DMS licensed contractor conducted exotic invasive plant control between June 20 and August 14, 2013. In September 2015, invasive species control treatments were conducted using a variety of treatment applications such as: cut -stump, foliar, hand pull, and hand digging methods. Invasive species that were treated throughout the conservation easement in September 2015 included Kudzu, multi -flora rose, privet, mimosa, autumn olive, trifoliate orange, tree of heaven, and Bradford pear. As with the SPAs, the first number in the VPA naming convention references the monitoring year in which the VPA was identified during the visual assessment. A brief description of the VPAs reported from previous year's assessment that have persisted as well as Year 4 VPA's is discussed below. All VPAs are included in the scoring of easement acreage performance categories in Tables 6a and 6b, and are also summarized in Table 6c, Figure 2 (CCPV), and the VPA photolog. VPA2-4 is located on UTI Reach B within vegetation monitoring plot 22 on the right floodplain terrace. The area has received treatment applications in the past; however, though the overall populations of multi -flora rose and Japanese honeysuckle within this area have diminished, they continue to persist. The combined total acreage is 0.03 acres, or 0.3% of the planted area acreage for this assessment tract. Two VPAs of invasive species also continue to persist after treatment along UT2 (VPA4-3 and VPA4-5). Both VPAs are located within the floodplain. VPA4-3 consists of both multi -flora rose Year 5 Site Assessment Report - Michael Baker Engineering, Inc. Hoppers Creek — Melton Farm Stream Restoration Project NCDEQ — DMS (Prof. No. 9225 1) May 2016 Page 6 of 7 and Japanese honeysuckle, while VPA4-5 is comprised primarily of the latter. VPA4-3 encompasses the majority vegetation monitoring plot 14. The combined total acreage for these two VPAs is 0.06 acres, or 4.0% of the planted area acreage for this assessment tract. Though there were no other VPAs which exceeded the mapping threshold, individual stems and/or localized populations of invasive species were observed throughout the assessment area. These species consisted primarily of multi -flora rose; however, Chinese privet and Japanese honeysuckle were also noted. Locations of these species were mainly limited to the fence line along the easement with a few sporadic populations within the planted easement areas.
