An additional 1,071 LF of stream along portions of UT1 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 UT1 of which 1 23 acres comprised restoration MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 1 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR I MONITORING REPORT NOVEMBER 2012, MONITORING YEAR 1 OF 5 and 0 33 acres comprised enhancement The Priority 1 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 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 UT1 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 and VPA2, were documented in the wetland area located on the right floodplain along South Fork Hoppers Reach 1 The combined total area for these VPAs was 0 12 acres, or 2 8% of the planted area acreage for this assessment tract The UT2 vegetation assessment tract did not perform as well because of the widespread infestation of invasive species associated with VPA3 and VPA4 These two VPAs were solely confined to UT2 Reach B and made up a combined total of 0 27 acres, or 18% of the 15 acre easement area for the UT2 vegetation assessment tract Invasive vegetation in these VPAs includes multiflora rose (Rosa multiora), Chinese privet (Ligustrum sinense), and Japanese stilt grass (Microstegium vimineum) 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 planview (CCPV) figures, supporting data tables, and photo logs, the contents of Appendix B was submitted to NCEEP in June 2012 and served as the interim visual site assessment report The success criteria or survival threshold for all 12 vegetation monitoring plots at the Project site were attained and are summarized in Tables 7 and 9 of Appendix C The average density of total planted stems or tract mean (including volunteers), based on data collected from the 12 monitoring plots during Year 1 monitoring, is 1,184 stems per acre, this further indicates that the Project site is on track for meeting the minimum success interim criteria of 320 trees per acre by the end of Year 3 and the final success criteria of 260 trees per acre by the end of Year 5 It should be noted that most vegetation plots exhibiting a lower planted stem density count are offset by the presence of thriving volunteer species, thereby boosting or increasing the stem density for a given plot and the tract in general upon inclusion of volunteers for total stems per acre Tables 5a through 5d (Appendix B) indicate the Project site was geomorphically stable overall and performing at 100% for the majority of parameters evaluated within the lateral /vertical stability and in- stream structure performance categories UT 1 Reach B was performing at 100% for all sub - categories South Fork Hoppers Creek Reaches 1 and 2, and UT2 (Reaches A and B) had sub - categories receiving scores of less than 100% namely due to small localized areas of bank scour and/or piping under structures Stream problem areas (SPAs) correlating with these areas of instability for these three project reaches were 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 Appendix B which includes a technical memorandum, CCPV figures, supporting data tables, and photo logs 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 The riffle and pool cross - sections located on UT1B, X9 and X10 respectively, exhibited small decreases in bankfull area, width, and maximum depth due to minor aggradation within the channel and floodplain, and bank height ratio slightly increased to between 12 to 1 3 respectively as a result of the floodplain deposition However, grade control structures (constructed riffles and log sills) continue to help maintain the overall profile desired on UTIB with consistent pool spacing, riffle slopes and riffle lengths as compared to the baseline conditions profile Aggraded areas are evident within the upstream limits of the UT B profile, and may stem from a transition to a lower channel slope upon entering the upstream project limits, but should flush downstream during larger storm flows over MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR I MONITORING REPORT NOVEMBER 2012, MONITORING YEAR I OF 5 time The profile for South Fork Hoppers Creek (Reaches 1 and 2) indicates that the bed features are generally stable as well, pools are well - maintained, having increased in depth in many areas, while pool spacing has decreased from the development of micro -pools nested within larger pools located in meander bends Six cover log (invert) survey points were removed from the mainstem profile plot since they were mistakenly symbolized as log sills during the baseline survey and erroneously appeared in the maximum depth of pools on the profile overlay for Year 1 The pebble count data for South Fork Hoppers Creek and UT1B indicate that the stream is moving fines through the system and larger pebbles are making up a greater percentage of the bed material The site was found to have had at least two bankfull events based on crest gauge readings Information on these events is provided in Table 12 of Appendix E It should be noted that many pools located downstream of log sills have shown a significant increase in depth of a foot or more along Reaches 1 and 2 and UT1B since the baseline survey The profile indicates that the maximum depth (dma,,) of the majority of these pools along these reaches is at or within the stable design tolerance originally proposed for these constructed Rosgen C type channels— reaches 1 and 2 were designed with a dma, ranging between 2 and 2 7 feet and UTIB with a dm ranging between 1 and 2 feet There are ax three pools located on South Fork Hoppers Creek mainstem (Reaches 1 and 2) and three pools located on UT1B where dma,, design values were exceeded, or reported to be greater than 2 7 and 2 feet respectively, one of the three pools along the mainstem is located downstream of the cross -vane These pools are approximately located at stations 16 +16, 19 +40, and 20 +21 along the mainstem, and at stations 19 +19, 19 +31, and 19 +44 along UT1B All these pools coincide with that portion of the longitudinal channel profile having the highest valley and channel slope of each reach except for the pool located at station 16 +16 along the mainstem The significant increase in pool depths in these areas may be correlated to areas of higher vertical energy dissipation due to higher valley /channel slopes as compared with shallower pools located in flatter areas of the profile In- stream structures located upstream and downstream of these deep pools are stable and holding grade, and pool length adjustment has been minimal as a result These deep pools are providing excellent in- stream habitat structure Pool depths (of all pools) within the Project are expected to fluctuate and adjust in response to storm events and sediment input of various magnitudes as the channel maintains the average channel geometry over time Baker will continue to monitor these pools during subsequent assessments Based on the first growing season following site construction (March 30, 2011 - November 2, 2011), three of the four wetland areas met the success criteria for Monitoring Year 1 Groundwater conditions at Gauges 2, 3, and 4 each indicated saturated conditions existed for 86% to 100% of the time Gauge 1 is located downstream of the easement crossing of South Fork Hoppers Creek in an area that was historically drier than the other wetland areas and failed to meet the wetland success criteria Although there were several episodes where the wetland around Gauge 1 experienced saturated soil conditions, the longest period the site remained saturated was 10 consecutive days 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 EEP's websrte 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 (EEP 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 EEP on -call design and construction services contract All raw data supporting the tables and figures in the appendices is available from EEP upon request MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 1 MONITORING REPORT NOVEMBER 2012, MONITORING YEAR 1 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 EEP 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 1 monitoring data was collected in May 2012 and September 2012 All visual site assessment and vegetation monitoring plot data was collected on May 30`h All stream survey (channel dimension and profile) and sediment data were collected between September 10th and 12'h Stream survey data was collected using a Topcon GRS -1 network Rover GPS unit which collects point data with an accuracy of less than one tenth of a foot 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 will be used for cross - sections and consistently referenced to facilitate comparison of year -to -year data The cross - sectional surveys will include points measured at mayor 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 UT1 B, 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, EEP PROJECT NO - 92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 1 MONITORING REPORT NOVEMBER 2012, MONITORING YEAR 1 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 floodplam 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 2.1.3.2 Structure Photos MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 1 MONITORING REPORT NOVEMBER 2012, MONITORING YEAR 1 OF 5 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 sites, which included one wetland vegetation plot The total number of quadrants was calculated using the CVS -NCEEP Entry Tool Database version 2 2 7 (CVS - NCEEP, 2007) 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 3O`h, 2012, the vegetation condition of planted vegetation along stream banks, floodplains (wetlands), and terraces were qualitatively evaluated for performance, this also Included the documentation of invasive species and potential WAS 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, EEP PROJECT NO -

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 1 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 2012) 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 inform ation are provided following the narrative portion of this rep ort 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, • vegetation monitoring plot 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 most recent NCEEP 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 except for that of the vegetation monitoring plot counts, which were conducted in order to determine whether or Year 1 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc June 26, 2012 Page 2 of 6 not the success criteria was met per plot for illustrative purposes on the CCPV figures All other vegetation monitoring plot data (tables) will be included in Appendix C of the Year 1 annual monitoring report to be submitted later 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, UT 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 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, and thus resulted in two distinct vegetation assessment tracts Vegetation conditions for both tracts are reported in Tables 6a and 6b Baker performed the visual site assessment and collected vegetation monitoring plot data on May 30th, 2012 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, floodplams, 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 Vegetation plot data was collected as part of this assessment to determine the success criteria for illustrative purposes on the CCPV figures Photos were recorded at each vegetation monitoring plot and in locations of potential VPAs Year 1 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc June 26, 2012 Page 3 of 6 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 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 NCEEP 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 m -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% as the design intended for the majority of parameters evaluated within the lateral/vertical stability and m- stream structure performance categories UT1 Reach B was performing 100% for all sub - categories SFHC Reaches 1 and 2, and UT2 (Reaches A and B) had sub - categories receiving scores of less than 100% namely due to small localized areas of bank scour and /or to structural piping SPAS correlating with these areas of instability for these three project reaches were documented and summarized in Table 5e SPA and SPA2 were characterized by small localized areas of bank scour and are located across the channel from one another on SFHC Reach 1, SPA is located along the left bank and SPA2 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, and warrant stabilizing to prevent the spread of lateral instability further downstream Year 1 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc June 26, 2012 Page 4 of 6 SPA3 and SPA4 involve the piping of flow and bank scour, respectively, observed at the cross vane located downstream of the easement crossing in SFHC Reach 2 Since construction, flow has continued to pipe (SPA3) under the downstream sill and through both cross vane arms as a possible result of poor soil compaction, inadequate silting, and /or failing filter fabric The piping of flow through the vane arms may have become exacerbated by the bank scour and recent exposure of macropores reported along the back of the right vane arm for SPA4 Bankfull events appear to be diverting excess flow into the left and right floodplams, and scouring the back of the right (and end of the left) vane arm due to the transition of expanded flow from the (wide) upstream easement crossing area to a narrower cross - sectional area downstream Scoured areas around both vane arms should be stabilized to prevent additional piping that could potentially lead to the compromising of structural integrity over time SPAS consists of the piping of flow through a riffle cascade (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 (SPA6) Coarse riprap material had been deposited downstream atop the lowest elevation boulder sill, exposing the underlying filter fabric as a result 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 UT Reach B, Table 6b references the vegetation assessment tract associated with UT2 (Reaches A and B) The success criteria or survival threshold for all 12 vegetation monitoring plots located throughout both vegetation assessment tracts, were attained Vegetation conditions for SFHC Reaches 1 and 2, and UT Reach B were good and performing close to 100% for both, the planted acreage and mvasive /encroachment area categories, as shown in Table 6a Two bare areas, VPA1 and VPA2, were documented in the wetland area located in the right floodplain along SFHC Reach 1 The combined total area for these VPAs was 0 12 acres, or 2 8% of the planted area acreage for this assessment tract 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 UT2 vegetation assessment tract did not perform as well because of the widespread infestation of invasive species associated with VPA3 and VPA4 These two invasive VPAs were solely confined to UT2 Reach B and made up a combined total of 0 27 acres, or 18% of the 1 5 acre easement area for the UT2 vegetation assessment tract Invasive vegetation in Year 1 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc June 26, 2012 Page 5 of 6 these VPAs includes multiflora rose, privet, and Japanese stilt grass VPA3 and VPA4 border existing tree lines or stands throughout the UT2 Reach B riparian corridor and generally occupy the tops of both banks and portions of each terrace as well, VPA3 extends into a portion of vegetation monitoring plot 13 where privet was reported Existing stands of trees (such as those in UT2 Reach B) precluded removal of mvasives during construction and these can often be a source of invasive vegetation even after treatment since the soil matrix is undisturbed, leaving roots and seeds intact These areas were previously treated but were exhibiting new growth and are still persisting Year 1 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc June 26, 2012 Page 6 of 6 --- -- CE--------- CE- -
