(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 4 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 UT 1, 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 II 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 UT 1 of which 1.23 acres comprised restoration and 0.33 acres comprised enhancement. The Priority I channel design approach entailed raising the elevation MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. - 42251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 4 MONITORING REPORT - FINAL DECEMBER 2015, MONITORING YEAR 4 OF 5 of the channel to establish greater connectivity to the floodplain and to restore the hydrologic relationship between South Fork 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 UT 1, Reach B were good and performing close to 100% for both the planted acreage and invasive/encroachment area categories. Two bare areas or vegetation problem areas (VPAs), VPA1-1 and VPA1-2, were documented in the wetland area located on the right floodplain along South Fork Hoppers Reach 1. The combined total area for these WAS was 0.15 acres, or 3.4% of the planted acreage for this assessment tract. These two WAS were identified in the Year 1 monitoring period and carried over through Year 4. Six small areas with invasive plants were identified during the May 2015 assessment for a combined total area of 0.11 acres or 1.3% of the easement acreage. Invasive species were treated throughout the conservation easement in September 2015. Kudzu, multi -flora rose, privet, mimosa, autumn olive, trifoliate orange, tree of heaven, and Bradford pear were treated using cut -stump, foliar, hand pull, and hand digging methods. Additional treatment will be performed if invasive species 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 2015 and served as the interim visual site assessment report. The average density of total planted stems per plot ranges from 283 — 971 stems per acre with a tract mean (including volunteers) of 890 stems per acre. Volunteer species continue to thrive throughout the vegetation plots. The Project site is on track for meeting the final success criteria of 260 trees per acre by the end of Year 5. 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 and performing at 92 to 100% for the majority of parameters evaluated within the lateral/vertical stability and in - stream structure performance categories. 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 were documented and summarized in Table 5e of Appendix B. A total of six SPAS that were identified in Year 1 and Year 2 monitoring periods were carried over through Year 4. No new SPAS were identified for the Year 3 assessment; however, three new SPAS were identified in Year 4. SPA4-1 and SPA4-2 are located on SFHC Reach 1 around stations 16+25 and 20+75, respectively. Both SPAS are characterized by failing rootwads associated with the erosion and undercutting of the bank tie-in just downstream of a log sill. SPA4-3 is located on UT2 Reach A between stations 12+36 to 12+53. The left bank in this location has scoured out due to the combination of high near bank stress during bankfull flows on the outside of a meander bend and topographic relief which has exacerbated the issue, but appears to be localized and not progressing downstream. A more detailed summary of the results for the visual stream stability assessment can be found 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 reach since construction. At this time, cross-sectional measurements 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 UTIB, which is most likely due to the natural movement of sediment through the system. Grade control structures (constructed riffles, cross vanes and log sills) continue to help maintain the overall profile desired. Visual observations and a review of pebble count data collected during Year 4 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 UT113 indicate that the stream is moving fines through the system and larger MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. - 92251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 4 MONITORING REPORT - FINAL DECEMBER 2015, MONITORING YEAR 4 OF 5 pebbles are making up a greater percentage of the bed material. The site was found to have had at least three bankfull events based on crest gauge readings. Information on these events is provided in Table 12 of Appendix E. Based on the fourth growing season following site construction (March 30, 2013 - November 2, 2015), all four wetland areas met the success criteria for wetland hydrology during Monitoring Year 4. Groundwater conditions indicated saturated conditions existed throughout 100% of the growing season for Gauges 2, 3, and 4, and 81 % of the growing season for Gauge 1. A summary plot of wetland gauge data as it relates to monthly precipitation is provided in Figure 7 of Appendix E; wetland areas and corresponding gauges are illustrated in the CCPV sheets (Figure2) in Appendix B. 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. - 42251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 4 MONITORING REPORT - FINAL DECEMBER 2015, MONITORING YEAR 4 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 4 monitoring data was collected in May 2015 and September 2015. All visual site assessment data was collected on May 6, 2015. Vegetation monitoring plot data was collected on September 21 and 24, 2015. All stream survey (channel dimension and profile) and sediment data were collected from September 21 - 23, 2015. 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 Muddy Creek As -built Survey. 2.1 Stream Assessment Geomorphic monitoring of restored stream reaches is being 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, will be 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 UT1B, 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 will include 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 UT113, and are provided in Figure 4 of Appendix D. Longitudinal profiles will be 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 4 MONITORING REPORT - FINAL DECEMBER 2015, MONITORING YEAR 4 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 will be 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 will be 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 will be 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 are taken once a year, from a height of approximately five to six feet. Permanent markers will 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 4 MONITORING REPORT - FINAL DECEMBER 2015, MONITORING YEAR 4 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 will make every effort to consistently maintain the same area in each photo over time. Lateral and structure photographs are 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, are 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 varies from 100 -square meters for tree species to 1 -square meter for herbaceous vegetation. Level 1 CVS vegetation monitoring will occur in spring, after leaf -out has occurred, or in the 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 will be calculated, and importance values will be determined. Individual seedlings will be marked to ensure that they can be found in succeeding monitoring years. Mortality will be 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 are used to visually document vegetation success in sample plots. Reference photos of tree and herbaceous condition within plots are taken at least once per year. As part of the visual site assessment conducted on May 6, 2015, 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. MICHAEL BAKER ENGINEERING, INC., DMS PROJECT NO. - 42251 SOUTH FORK HOPPERS CREEK - MELTON CREEK STREAM RESTORATION PROJECT YEAR 4 MONITORING REPORT - FINAL DECEMBER 2015, MONITORING YEAR 4 OF 5 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 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 2015). 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.

Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Pagel of 8 1. 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 4 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 2015). 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, and • 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, and • 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 most recent 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 Year 4 Site Assessment Report — S. Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Page 2 of 8 will be summarized in Appendix C and the CCPV figure of the Year 4 annual monitoring report to be submitted in late November of this year. 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, UT1 Reach B, and UT2 (Reaches A and B). SFHC Reaches 1 and 2 are delineated by the confluence of UTI 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. Due to expected performance issues related to the persistence of invasive species on UT2 (Reaches A and B), vegetation conditions for it were assessed independently from the remainder of the Hoppers Creek -Melton Farm Stream Restoration Project site, which exhibited uniform conditions; therefore, resulting in two distinct vegetation assessment tracts. Vegetation conditions for both tracts are reported in Tables 6a and 6b. Baker performed the visual site assessment on May 6, 2015. 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. Year 4 Site Assessment Report — S. Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Page 3 of 8 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 and AutoCAD 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, geolifts, 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 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 100 percent as the design intended for the majority of parameters evaluated within the lateral/vertical stability and in - stream structure performance categories. UT1 Reach B was functioning at the highest level geomorphically out of all the stream project reaches, performing at 100 percent for all sub- categories except for `Riffle Condition'—two riffles located within the upstream project limits (at stations 10+00 and 12+00) were covered in fines from an upstream sediment source but the coarse riffle substrate appeared intact beneath the fines. SFHC Reach 1 received the lowest performance scores (for all 3 major morphological channel categories) in terms of lateral, vertical, and in -stream structural stability out of all the project stream reaches followed by SFHC Reach 2 and UT2 (Reaches A and B). SFHC Reaches 1 and 2, and UT2 (Reaches A and B) had more than one sub -category receiving scores of less than 100 percent namely due to one or more of the following issues: localized areas of lateral instability or bank erosion from bank scour and bank slumping, and the piping or failure of engineered in - stream structures; SPAs correlating with these issues for these three project reaches were documented and summarized in Table 5e. There were a total of nine SPAs documented, four of which were identified during the Year 1 visual assessment, two that were identified during the Year 2 assessment, and three that were identified during the Year 4 assessment. SPAs documented in previous years were included in this assessment since they have persisted to date. Any SPAs that have been documented in previous reports, but were not indicated as problems during the Year 4 assessment will not be described. Year 4 Site Assessment Report — S. Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Page 4 of 8 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 1-1 and SPA 1-2 are characterized by small localized areas of bank scour and are located across the channel from one another on SFHC Reach 1. SPA 1-1 is located along the left bank, and SPAI-2 is located along the right bank a little further downstream. The invert along these two sills are sloped to one side (slanted) and oriented within the channel such that flow is being directed toward the bank immediately downstream of where the log sill ties into the bank, causing bank erosion. Banks of both SPAs are vertical and exposed, but are slowly stabilizing with native well rooted vegetation. Stabilization is critical to prevent the spread of lateral instability further downstream. SPA 1-5 consists of the piping of flow through 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 for mitigation credit. Upon inspection, the channel bed of the downstream riffle cascade had eroded (SPA1-6) and the right upper bank has eroded. Coarse riprap material has been deposited downstream atop the lowest elevation boulder sill, exposing the underlying filter fabric as a result. SPA2-1 is located downstream of a meander bend between stations 15+95 and 16+32 on SFHC Reach 1. SPA2-1 is characterized by a failing rootwad associated with the erosion and undercutting of the left bank located immediately downstream of a log sill around station 16+25. The invert along the upstream log sill is sloped to one side (slanted toward the left bank) and is oriented within the channel such that flow is being directed toward the left bank immediately downstream of where the log sill ties into the bank, causing bank erosion. Erosion along the left bank appears to have subsided, but has scoured the upstream portion of the rootwad and the channel toe beneath it, undermining the structure. The rootwad has separated from the left bank, has slumped into the channel, and is no longer affording erosion protection of the left bank. Native herbaceous and woody vegetation are starting to colonize the problem area. This area should be continually monitored to document and prevent any further bank degradation SPA2-3 involves localized scour along the left bank of a riffle located upstream of the easement crossing between stations 18+75 and 18+87. Flow has scoured out and eroded a small portion of the left bank behind a cluster of well rooted, native vegetation that is thriving at the bank. The vegetation is comprised primarily of willow oak, tag alder, and soft rush. Year 4 Site Assessment Report — S. Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Page 5 of 8 Matting along the bank is generally intact but has separated from the bank in areas due to erosion over time that has caused the bank to recede. The left bank is vertical and exposed, but vegetation is starting to provide surface protection. The thalweg along the riffle where SPA2-3 is located appears to be centered, but velocity vectors, and thus flow, may have been temporarily redirected toward the left bank during past storm events from slight temporal shifts in aggraded riffle material within the riffle, thereby increasing stress along the left bank and making the bank more susceptible to subsequent erosion. SPA4-1 is located downstream of a log step on SFHC Reach 1. SPA4-1 is characterized by a failing rootwad associated with the erosion and undercutting of the right bank located immediately downstream of a log sill around station 16+25. The invert along the upstream log sill is sloped to one side (slanted toward the right bank) and is oriented within the channel such that flow is being directed toward the right bank immediately downstream of where the log sill ties into the bank, causing bank erosion. The rootwad has separated from the right bank, has slumped into the channel, but is still providing erosion protection of the right bank. Native herbaceous and woody vegetation are present and are providing some stability to the bank. This area should be continually monitored to document and prevent any further bank degradation. SPA4-2 is located downstream of a log step on SFHC Reach 1. SPA4-2 is characterized by a failing rootwad associated with the erosion and undercutting of the left bank located immediately downstream of a log sill around station 20+75. The invert along the upstream log sill is sloped to one side (slanted toward the left bank) and is oriented within the channel such that flow is being directed toward the left bank immediately downstream of where the log sill ties into the bank, causing bank erosion. There is erosion immediately upstream of the rootwad potentially compromising the structure, but the rootwad is still providing some bank protection. Native herbaceous and woody vegetation are present and are providing some stability to the bank. This area should be continually monitored to document and prevent any further bank degradation SPA4-3 is located on UT2 Reach A between stations 12+36 to 12+53. The left bank in this location has scoured out due to the combination of high near bank stress during bankfull flows on the outside of a meander bend and topographic relief which has exacerbated the issue. This area is localized and does not appear to be progressing downstream. Log sills associated with deep scour pools on UTI Reach B 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 these scour pools could potentially pose a threat and undermine the structural integrity and grade control function to their upstream log sill counterpart considering the small channel dimensions associated with this stream reach. Pools for UTI Reach B were designed to have a maximum pool depth (dpoo,) ranging between 1.0 and 2.0 feet and a ratio of pool depth to average bankfull depth (dpoo,/dbkf) ranging between 2.0 and 4.0 (as cited in Table 7.2 from the South Muddy Creek Stream Restoration Plan). DMS' monitoring guidance (dated November 7, 2011) for defining `sufficient depth' for meander pool condition suggests that a pool should have a dpoo,/dbkf ratio greater than or equal to 1.6, which in this case for UTI Reach B translates to a Year 4 Site Assessment Report — S. Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Page 6 of 8 dpoo, of 0.8 feet in depth or greater. All log sill scour pools on UT 1 Reach B had dpoo,/db,f ratios exceeding 1.6 and thus fulfilled DMS' monitoring guidance criteria for sufficient depth for meander pool condition for this current visual morphological assessment. The deepest of these pools were the three log sill scour pools located downstream of the easement crossing between stations 19+00 and 19+50. The upstream most log sill remains the deepest of the three and had a dpoo, value and dpoo,/dbkf ratio of 2.8 feet and 5.2 respectively. This marks a slight increase in dpoo, value and dpoo,/db,f ratio of 2.2 feet and 4.4 recorded in the Year 3 Assessment. Even though the dpoo, value of 2.8 feet exceeds that specified for the proposed design (by 0.8 feet), it still meets DMS' monitoring guidance criteria for the assessment. These log sill structures were constructed with a header and footer log. The footer log at this particular 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. Like other pools throughout the project site, the depth of this pool should fluctuate and fill in with sediment over time in between storm events. Fine sediment was noted in this pool and other pools throughout the reach reinforcing pool depth filling and fluctuation. These log sills/scour pools will continue to be monitored in subsequent years. 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 fourteen VPAs, two of which were identified during the Year 1 visual assessment, three that were identified during the Year 2 assessment, and nine that were identified during the Year 4 assessment. Bare floodplain conditions account for two of the VPAs, and the presence of invasive species accounts for the remaining twelve VPAs. A DMS licensed contractor conducted exotic invasive plant control over nine days between June 20 and August 14, 2013. No additional treatments have been conducted since these treatments. As a result several new VPAs were identified in the Year 4 assessment. 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 persisting VPAs reported from previous year's assessment, as well as Year 4's VPAs are 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. VPA1-1 and VPA1-2 are the two bare areas that were documented in the Year 1 Assessment in the wetland area located in the right floodplain along SFHC Reach 1. The two VPAs have remained somewhat bare since construction was completed. This could possibly be due to standing water from frequent inundation and/or the washing away of dispersed seeds by frequent overbank flows. The combined total area for these VPAs is 0.15 acres or 3.4% of the planted area acreage for this assessment tract. One VPA reported during the Year 2 Assessment within SFHC Reach 2 (VPA2-2) still persists. It is located around a patch of trees in the left floodplain and is composed of Year 4 Site Assessment Report — S. Fork Hoppers Creek NCDEQ — Division of Mitigation Services Michael Baker Engineering, Inc. May 2015 Page 7 of 8 multiflora rose. The combined total area for this VPA is 0.019 acres or 0.4% of the planted area acreage for this assessment tract. Two VPAs were reported within SFHC Reach 2 (VPA4-1 and VPA4-2,) during the Year 4 Assessment. They are located in the left and right terrace. These VPAs are composed primarily of multiflora rose and Japanese honeysuckle and continue to persist after prior treatment. Both VPAs appear to be the result of encroachment from outside the easement. The combined total acreage for these seven VPAs is 0.035 acres or 0.8% of the planted area acreage for this assessment tract. Two VPAs reported during the Year 2 Assessment within UTI Reach B (VPA2-4 and VPA2- 5) still persist. They are located on the right terrace/floodplain and are composed primarily of multiflora rose and Japanese honeysuckle that continue to persist after prior treatment. VPA2-4 is located in vegetation monitoring plot 22 and has grown in size from previous year's assessment. The VPA may have proliferated from seed sources contained within the existing tree stand located just outside the vegetation plot. The combined total area for these two VPAs is 0.04 acres or 0.9% of the planted area acreage for this assessment tract. One VPA was reported within UT 1 B (VPA4-9) during the Year 4 Assessment. This problem area is located on the right terrace. This VPA is composed of Japanese honeysuckle that has persisted after treatment as result of encroachment from outside the easement. The combined total acreage for these four VPAs is 0.02 acres or 0.4% of the planted area acreage for this assessment tract. Six VPAs were reported within UT2 (VPA4-3, VPA4-4, VPA4-5, VPA4-6, VPA 4-7, and VPA4-8) during the Year 4 Assessment. All are located in the left floodplain or terrace except for VPA4-4, which is located in the right terrace. These VPAs are composed primarily of multiflora rose and Japanese honeysuckle that continue to persist after prior treatment. The combined total acreage for these six VPAs is 0.11 acres or 8.1 % of the planted area acreage for this assessment tract. Year 4 Site Assessment Report — S.

Stream Problem Areas South Fork Hoppers Creek - Melton Farm Restoration Project: DMS Project No. 92251 South Fork Hoppers Creek (SFHC) Reach 1 Feature Issue Station No. Suspected Cause Photo Number* Scour eroding the left bank immediately downstream of log sill invert/left bank tie-in. 14+20 to 14+26 Appears to be a localized area of high near SPA1-1 bank stress caused by flow (velocity vector) Bank Scour directed at the left bank by log sill orientation. Scour eroding the right bank immediately downstream of log sill invert/right bank tie-in. 14+40 to 14+50 Appears to be a localized area of high near SPA1-2 bank stress caused by flow (velocity vector) directed at the left bank by log sill orientation. Rootwad failure and undercut banks along the left bank immediately downstream of log sill invert/left bank tie-in. Appears to be caused by bank scour upstream and beneath the rootwad Engineering structures - Rootwad Failure 16+12 to 16+32 resulting from flow (velocity vector) directed at SPA2-1 the left bank by log sill orientation which eventually undermined the rootwad, to where it separated from the left bank, slumping into the channel. SFHC Reach 2 Feature Issue Station No. Suspected Cause Photo Number Localized scour along the left bank behind well rooted bank vegetation thriving at the toe of Bank Scour 18+75 to 18+87 channel causing erosion in between the left SPA2-3 bank and the well -rooted vegetation (primarily comprised of Willow Oak, Tag Alder, and Soft Rush). Rootwad failure along right bank due to undercutting along bank. Appears to be caused 20+25 by high near bank stress caused by flood flow SPA4-1 stream energy vectors being directed at bank. Engineering structures - Rootwad Failure Rootwad failure along left bank due to undercutting along bank. Appears to be caused 20+75 by high near bank stress caused by flood flow SPA4-2 stream energy vectors being directed at bank. UT2 Reach A Feature Issue Station No. Suspected Cause Photo Number Flow piping within riffle cascade and around Piping 13+40 downstream log sill due to possible tear in filter SPA1-5 fabric or lack of sealing from re -sorting of alluvial material and silt. Left bank scour on outside bend. Appears to be Bank Scour 12+36.50 to 12+53.50 caused by high near bank stress during bankfull SPA4-3 storm events. Ephemeral Drainage (near upstream extents of UT2)** Feature Issue Station No. Suspected Cause Photo Number Scour of riffle cascade from large storm events Riffle cascade downstream of second over time has eroded the channel bed, Bed Scour/Degradation boulder sill depositing the coarse riffle substrate SPA1-6 downstream, and exposed the underlying filter fabric. *Note: The first digit in the Photo Number column references the monitoring year and the second digit references the problem area or photo (which would be identical to a prior years problem area/photo number when persisting from a previous monitoring year). **Not being sought for mitigation Table 6a.
