92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 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 floodplam 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 -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 12 acres, or 2 8% of the planted acreage for this assessment tract These two VPAs were identified in the Year 1 monitoring period and carried over into Year 2 Six small areas with invasive plants were of concern and were identified for a combined total area of 0 08 acres or 0 9% of the easement acreage The UT2 vegetation assessment tract did not perform as well because of the widespread infestation of invasive plant species associated with VPA1 -3 and VPA1 -4 These two WAS were solely confined to UT2 Reach B and made up a combined total of 0 29 acres, or 19 3% of the 15 acre easement area for the UT2 vegetation assessment tract These two WAS were also identified in the Year 1 monitoring period and have increased slightly in size over time Invasive vegetation in these WAS includes multiflora rose (Rosa multiflora), 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 ( CCP figures, supporting data tables , and photo logs The contents of Appendix B were submitted to NCEEP in May 2013 and served as the interim visual site assessment report A NCEEP licensed contractor conducted exotic invasive plant control over nine days between June 20 and August 14, 2013, spread out so far due to rain interfering with times for effective treatment Species treated, using cut - stump, foliar, and hand pull methods, were Chinese Privet, Multiflora Rose, Kudzu, Silverthorn, Mimosa, Trifoliate Orange, Callery Pear, two Burning Bushes and one Tree of Heaven Cut -stump treatment was also performed on the larger, climbing Japanese Honeysuckle Garlon 3A was used for cut -stump and Glyphomate 41 was used for foliar treatment 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 2 monitoring, is 850 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 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 has remained geomorphically stable overall and performing at 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 piping under 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 Five SPAS were identified in the Year 1 monitoring period and carried over into Year 2 Five new SPAS were Identified for the Year 2 monitoring period A more detailed summary of the results for the visual stream stability assessment can be found in Appendix B MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 OF 5 f 1 I � 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 adjustments that have occurred have primarily been observed in riffle cross - sections that are exhibiting signs of narrowing Based on field observation, this narrowing can be attributed to herbaceous vegetation becoming well established over the second year 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, and they have increased in depth in many areas 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 2 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 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 one bankfull event based on crest gauge readings Information on these events is provided in Table 12 of Appendix E Based on the second growing season following site construction (March 30, 2011- November 2, 2011), all four wetland areas met the success criteria for Monitoring Year 2 Groundwater conditions at Gauges 2, 3, and 4 indicated saturated conditions existed for 100% of the growing season 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 Gauge 1 failed to meet the minimum wetland success criteria during Year 1 monitoring, but met the criteria in Year 2 Gauge 1 was saturated for 25 days or 12% of the growing season 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 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 (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 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 2 monitoring data was collected in May 2013 and August 2013 All visual site assessment data was collected on May 10, 2013 Vegetation monitoring plot data was collected on September 23, 2013 All stream survey (channel dimension and profile) and sediment data were collected August 15, 2013 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 MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 3 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 OF 5 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 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 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 UT1B, and are provided in Figure 4 of Appendix D Longitudinal profiles will be replicated annually during the five year monitoring period 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 nffles 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 nffle 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 MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 HOPPERS CREEK- MELTON FARM STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 OF 5 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 ti 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 r 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 Photographs of primary grade control structures (i a 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 MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 92251 HOPPERS CREEK - MELTON FARM STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 OF 5 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 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 10, 2013, 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 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 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 meteorological station (NC -MD -2) will also be downloaded annually for the five years of groundwater monitoring conducted post - construction, this station is located in close proximity to Marion, NC This data will be obtained from the State's Climate Office website (CRONOS 2012) 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 MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO -

PROGRAM Year 2 Site Assessment Report — S. Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc. May 31, 2013 Page 1 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 2 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 2013) The report describes protect 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 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 Vegetation monitoring plot counts were excluded from this assessment but will be conducted after July 2013, this data Year 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 2 of 8 i! i will be summarized in Appendix C and the CCPV figure of the Year 2 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, UT Reach B, and UT2 (Reaches A and B) SFHC Reaches 1 and 2 are delineated by the confluence of UT1 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 on May 1", 2013 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 m -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 I 1 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, i 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 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 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 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 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 protect 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 mayor morphological channel categories) in terms of lateral, vertical, and m -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 10 SPAs documented, 5 of which were identified last year during the Year 1 visual assessment and 5 that were newly identified during this current assessment As alluded to previously, SFHC Reach 1 contains the most SPAs (4) out of all the project stream reaches SPAs documented last year were included in this assessment since there has been Year 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 4 of 8 minimal to no treatment implemented to date 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 Because the SPAS reported from last year's assessment remained unchanged in condition and scale when observed during this assessment, they will not be discussed in this memorandum, but 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 The two newly identified SPAs discovered on SFHC Reach 1, SPA2 -1 and SPA2 -2, are located in close proximity to each other on opposite banks downstream of a meander bend between stations 15 +95 and 16 +32 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 migrated further downstream over time, scouring the upstream portion of the rootwad and the channel toe beneath it, eventually 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 SPA2 -2 is located across the channel and just upstream from SPA2 -1 on the right bank, and consists of a slumping bank situated along the downstream portion of an outer meander bend The 15 LF section of calved right bank has separated but not yet slumped into the channel Flow behind the separated bank threatens to continue to erode and expose the parent bank which is vertical and devoid of stabilizing vegetation Bank slumping of SPA2 -2 may be a result of poor soil compaction during construction and/or the unconsolidated nature of the soil matrix within the bank, which without adequate vegetation to help reinforce or stabilize the bank is easily erodible This is evident as the mass wasting along the right bank extends about 15 LF downstream along one continuous fissure to the log sill associated with SPA2 -1 The tie -in of the log sill along the right bank around station 16 +10 is slightly exposed as a result, the sill appears to be fully functional as grade control, but may become structurally compromised if scour behind the slumped bank material persists over time 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 wallowed out and eroded a small portion of the left bank behind a cluster of well rooted, native vegetation that is thriving at the channel toe of the bank The vegetation is comprised primarily of Willow Oak, Tag Alder, and Soft Rush Matting along the bank is generally intact but has separated from the bank in areas due erosion over time that has caused the bank to recede. The left bank is vertical, exposed, and devoid of vegetation and 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 near bank and making the bank more highly susceptible to subsequent erosion Year 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 5 of 8 SPA2 -4 is located on UT2 Reach B and is a steep portion of left bank located across from vegetation plot 13 that is slumping and separating from the top of terrace This bank was originally stabilized during construction by a combination of bank grading, temporary/permanent seeding, the installation of staked matting, and the plantmg of live - stake vegetation The graded bank began to slump before construction was completed and was re- stabilized before demobilization and project closeout The cause of the recurrent bank instability at SPA2 -4 may potentially be a result of poor soil compaction and overland storm flow seepage that appears to be occurring at the top of terrace which may be undermining the re- graded bank SPA2 -5 consists of the piping of flow through a riffle cascade (log sill) structure at station 12 +90 in UT2 Reach A The structure is vertically and laterally stable Some water was observed flowing over the log sill invert, the log sill should re -seal over time Log sills associated with deep scour pools on UT1 Reach B were inspected and assessed for vertical stability per EEP's request EEP's concern was that the vast 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 UT1 Reach B were designed to have a maximum pool depth (dPoo,) ranging between 10 feet and 2 0 feet and a ratio of pool depth to average bankfull depth (dPoo, /db,f) ranging between 2 0 and 4 0 (as cited in Table 7 2 from the South Muddy Creek Stream Restoration Plan) EEP's monitoring guidance (dated November 7, 2011) for defining `sufficient depth' for meander pool condition suggests that a pool should have a dPoo, /db,f ratio greater than or equal to 16, which in this case for UT1 Reach B translates to a dPoo, of 0 8 feet in depth or greater All log sill scour pools on UT1 Reach B had dPoo, /db,f ratios exceeding 1 6 and thus fulfilled EEP's monitoring guidance criteria for sufficient depth for meander pool condition for this current visual morphological assessment The deepest of these pools were those three log sill scour pools located downstream of the easement crossing between stations 19 +00 and 19 +50 The upstream most log sill was the deepest of the three and had a dPoo, value and dPoo, /db,f ratio of 2 5 feet and 5 0 respectively Even though the dPoo, value of 2 5 feet exceeds that specified for the proposed design (by 0 5 feet), it still meets EEP's 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 These log sills /scour pools will continue to be monitored in subsequent years Year 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 6 of 8 3.2 Vegetation Condition Assessment Tables 6a and 6b summarize the vegetation conditions of the Hoppers Creek - Melton Farm f Stream Restoration site Table 6a references the vegetation assessment tract associated with SFHC Reaches 1 and 2, and UT1 Reach B, Table 6b references the vegetation assessment tract associated with UT2 (Reaches A and B) There were a total of 9 VPAs, 4 of which were ; identified last year during the Year 1 visual assessment and 5 that were newly identified during the current assessment All 5 newly identified VPAs were located on the SFHC Reaches 1 and 2/UT1 Reach B vegetation assessment tract VPAs documented last year were included in this assessment since there has been no treatment implemented to date (although treatment is scheduled sometime this year) 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 Most of the VPAs (except VPA1 -3) reported from last year's assessment remained unchanged in size and species composition when observed during this assessment, and therefore will not be discussed in this memorandum, but all 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 Vegetation conditions for SFHC Reaches 1 and 2, and UT1 Reach B were good and ' performing close to 100 percent for both, the planted acreage and invasive /encroachment area categories, as shown in Table 6a Invasive species were not present during last year's assessment throughout these reaches but were observed for the first time during this current assessment, occurring in seven discrete areas totaling approximately 0 08 acres or 0 9 percent of the total easement acreage The largest of these areas were VPA2 -1, VPA2 -2, and VPA2 - 3 which are all located within the upstream and downstream limits of the SFHC mainstem, and are all composed of multiflora rose (Rosa multiflora) and privet (Ligustrum smense) The close proximity of VPA2 -1 and VPA -2 -3 to the project easement boundary makes these areas more susceptible to the encroachment of mvasive vegetation from outside the easement where invasive vegetation is thriving and has not been treated, VPA2 -1 may also have been caused by the proliferation of a seed source in the adjacent VPA1 -4 VPA2 -2 appears to have been caused by a combination of invasives persisting after treatment and from intact seed sources contained within the existing tree stand cluster in which VPA2 -2 is situated The three VPAs reported within UT1 Reach B are all located in the right floodplain or terrace and are composed primarily of multiflora rose (Rosa multiflora) that seems to have persisted after prior treatment VPA24 is located on the eastern periphery of vegetation monitoring plot 22 and may have proliferated from seed sources contained within the existing tree stand located just outside the vegetation plot The UT2 vegetation assessment tract did not perform as well once again because of the widespread infestation of invasive species associated with VPA1 -3 and VPA1 -4 While VPA 1 -4 has remained unchanged in size and composition, VPA 1 -3 has increased in area by 0 02 acres since last year's assessment, extending up the valley along the left bank of UT2 Reach B approximately 130 LF These two invasive VPAs were solely confined to UT2 Reach B and made up a combined total of 0 29 acres, or 19 3 percent of the 1 5 acre easement area for the UT2 vegetation assessment tract (a total increase of 0 02 acres or 13 percent of the easement acreage since last year's assessment) Invasive vegetation in these VPAs Year 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 7 of 8 I 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 It appears that several pine trees were recently cut down Just outside of the easement along the left floodplam/terrace of UT1 Reach B A few of these pine trees fell inside vegetation monitoring plots 21 and 23 These downed trees may have damaged some native buffer plantings located inside and out of the vegetation plots EEP and the landowner were notified and the trees are to be removed by the landowner before the end of June 2013 in time for the Year 2 vegetation plot counts to be conducted Year 2 Site Assessment Report — S Fork Hoppers Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 8 of 8 ----- CE--------- CE- - - -- — • — • — • — • — - — • — • — CONSERVATION EASEMENT ASBUILT CENTERLINE SURVIVAL THRESHOLD MET?
