737 SOUTH MUDDY CREEK STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013. MONITORING YEAR 2 OF 5 Invasive areas of concern were observed and documented accordingly in Table 6a and as vegetation problem areas (VPAs) in Figure 2 and Table 6b (Appendix B) Eighteen discrete areas of invasive species were - documented throughout the site and totaled approximately 126 acres, or 7 4 percent of the total easement acreage 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 was submitted to NCEEP in May 2013 I and served as the interim visual site assessment report - A NCEEP licensed contractor conducted exotic invasive plant control on the project site during the 2013 growing season In addition, exotic invasive plant species will also be treated on the project site during the 2014 growing season The success criteria or survival threshold for all 12 vegetation monitoring plots 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 651 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 Table 5a in Appendix B, indicates the South Muddy Creek site is 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 six sub - categories receiving scores of less than 100% correspond to the five stream problem areas (SPAS) documented and summarized in Table 5b (Appendix B) The five SPAS I were characterized by localized areas of bank scour and were all located upstream of the Sam Road bridge 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 four permanent cross - sections in Appendix D show that there has been little adjustment to stream dimension within the Project reach since construction In general, riffles appeared to have narrowed in width slightly while pools show little to no change in (maximum) depth The longitudinal profile indicates that the bed features are generally stable and that grade control structures (constructed riffles and j- hooks) continue to help maintain the overall profile desired Pool lengths and depths appear to have been maintained with minor localized adjustments The Aggradation noted in the Year 1 Monitoring Report within the downstream limits of the Project reach profile along the meander bend beginning at station 36 +00 has begun to scour and return to a more stable maximum depth Scour within the aggraded meander bend, from larger, subsequent storm flows, should continue to flush the aggraded material downstream and help to re- establish a deeper pool over j time The site was found to have had at least one bankfull event based on crest gauge readings Information - on bankfull events is provided in Table 12 of Appendix E 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 includes the summary of constructed design approaches for South Fork Hoppers Creek (EEP Project No 92251), a nearby project site that was designed and constructed in conjunction with the South Muddy Creek 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 - 737 SOUTH MUDDY CREEK STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 OF 5 2.0 METHODOLOGY The five -year monitoring plan for the Project site includes criteria to evaluate the success of the vegetation and stream components of the project The methodology and report template used to evaluate these two 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 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 September 2013 All visual site assessment data contained in Appendix B was collected on May I" except for the vegetation plot data and corresponding plot photos which were collected on September 19th All stream survey (channel dimension and profile) and sediment data were collected on August 15'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, 4 permanent cross - sections, 1 crest gauge, and 20 photo identification points were installed 2.1.1 Morphologic Parameters and Channel Stability 2.1.1.1 Dimension Four 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 The two pairs of nffle and pool cross - sections are all located upstream of the Sam Road bridge crossing 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 One longitudinal profile was surveyed for the entire project length of the Project reach and is 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 - 737 SOUTH MUDDY CREEK STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 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 (at cross - section X4) during annual geomorphic surveys of the Project site This sample, 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 Is 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 left top of bank at station 22 +00 The bottom of the crest gauge coincides with the top of bank (bankfull) elevation The crest gauges record the highest watermark between site I 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 2.1.3.2 Structure Photos MICHAEL BAKER ENGINEERING, INC, EEP PROJECT NO - 737 4 SOUTH MUDDY CREEK STREAM RESTORATION PROJECT YEAR 2 MONITORING REPORT DECEMBER 2013, MONITORING YEAR 2 OF 5 i �_I 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 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 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 trees 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 trees and the current year's living, planted trees 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 the Year 5 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 1, 2013, the vegetation condition of planted vegetation along stream banks, floodplains, 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 2 monitoring services for the South Muddy Creek 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 project objectives, discusses the assessment methodology, summarizes assessment results, and documents potential stream and vegetation problem areas (SPAS and VPAs respectively) 1.2 Objectives The objectives of the site assessment were to • provide a general overview of stream morphological stability, • provide a general overview of vegetation conditions, • identify and document potential SPAs and VPAs 1.3 Supporting Data Supporting data and information are provided following the narrative portion of this report and include • current condition plan view (CCPV) figures (Figure 2, sheets 1 and 2), • visual stream morphology stability assessment table (Table 5a), • SPA inventory table (Table 5b), • vegetation condition assessment table (Table 6a), • VPA inventory table (Table 6b), • stream station photos, • SPA photos, • VPA photos 2 Methodology The methodology used for assessing overall stream and vegetation conditions at the South Muddy Creek 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 will be Year 2 Site Assessment Report — South Muddy Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 2 of 6 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 South Muddy Creek Stream Restoration Project site was evaluated as one project reach for each of the two components (SPA and VPA) This was done since the stream and riparian corridor are contained within one contiguous section along the mainstem of South Muddy Creek, site conditions appeared uniform allowing for an assessment as one reach and the project was assessed as one reach for the Final Baseline Monitoring Document/As -Built Report 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 in- stream structures throughout the project reach as a whole Habitat parameters, such as riffle embeddedness and pool depth maintenance, were also measured and scored The entire 2,7871mear foot 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 station (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 17 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 14 1 acres of riparian buffer planting zones within the easement boundary as part of the restoration design whereas invasive vegetation and encroachment areas of invasive species were evaluated for the entire 17 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 areas of invasive vegetation 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 reach in terms of stream morphology stability and vegetation condition using assessment forms provided by NCEEP Year 2 Site Assessment Report — South Muddy Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 3 of 6 3 Summary of Results 3.1 Visual Stream Morphology Stability Assessment Table 5a summarizes the performance of the South Muddy Creek Stream Restoration Project reach 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, rock/log j- ' hooks, 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 Table 5a As Table 5a indicates, the South Muddy Creek 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 m- stream structure performance categories The five sub- categories receiving scores of less than 100 percent corresponded to the five SPAS that i were documented and summarized in Table 5b All 5 SPAs were characterized by localized areas of bank scour and were all located upstream of the Sam Road bridge Two of the five SPAs documented in Table 5b, SPA1 -1 and SPA1 -2, were SPAs persisting from the Year 1 monitoring assessment (and are referenced as such by the first number in the SPA naming convention) SPA 1 -1 consists of a portion of undermined brush mattress along the right bank in an outer meander bend that has resulted in bank erosion The length of undercut and eroded bank along SPA1 -1 has increased from 10 linear feet (LF) to 80 LF, migrating 70 LF downstream in approximately one year or since this SPA was first documented in the Year 1 visual assessment The structural integrity of this brush mattress has become compromised Lateral instability along this outer meander bend is likely to continue migrating downstream if left unchecked over - time SPA 1-2 was still unstable laterally, but remained unchanged in length or severity of bank - erosion since it was first reported a year ago It appears that some aggraded riffle material at the head of riffle was splitting and directing flow toward the left bank (SPA1 -2) causing the bank to erode Regrading and uniformly distributing the aggraded riffle material throughout the riffle may prevent the diversion of flow toward the left bank thereby alleviating scour along this bank SPA1 -3 is no longer deemed an SPA due to a combination of vegetation growth holding the bank and erosional and depositional processes that have reduced the bank angle thereby improving bank stability in this area within the past year SPA2 -1 is an area of localized scour and bank erosion along both banks located within the upstream project reach limits between station 12 +30 and 12 +60 Bank instability was caused by high near bank stress from the diversion of flow around a recently removed beaver dam Year 2 Site Assessment Report — South Muddy Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 4 of 6 Erosion along the right bank is larger in magnitude and severity than the left bank since that portion of the right bank coincides with the transition between the outer meander bend and a riffle where higher velocities tend to be concentrated and near bank stress tends to be greater SPA2 -2 consists of a 60 LF length of brush mattress compromised by an undercut bank t between station 16 +70 and 17 +30, it is located along the right bank at the beginning of a meander bend The brush mattress (and a portion of the staked and matted bank) appears to be separating from the right bank and overhanging from a combination of poor soil compaction and scour along the toe of bank Some of the brush originally installed behind the matting to armor the bank has washed away leaving the bank exposed and vulnerable to subsequent erosion The bank protection provided by the remaining length of brush mattress along the right bank may become compromised and less effective over time if SPA2 -2 is not stabilized and the scour (and instability) is allowed to continue to migrate further downstream by undermining the brush - SPA2 -3 consists of an area of localized scour along the right bank located downstream of an outer meander bend between station 12 +30 and 12 +60 Bank scour could potentially be a result of the lack of centering of the thalweg immediately downstream of the upstream meander bend (and was noted accordingly in Table 5a) As a result, some velocity vectors within the riffle have been redirected toward the right bank instead of being centered in the riffle, thereby increasing near bank stress and causing the bank to erode The bank is vertical, exposed, devoid of vegetation and matted protection, and is mild to moderately eroded 3.2 Vegetation Condition Assessment Table 6a summarizes the vegetation condition of the South Muddy Creek Stream Restoration site The planted acreage performance categories were functioning at 100 percent with no bare areas, low stem density areas, or areas of poor growth rates /vigor to report Invasive areas of concern were observed and documented accordingly in Table 6a and as VPAs in Figure 2 and Table 6b There were a total of 15 VPAs, 8 of which were identified last year during the Year 1 visual assessment and 7 that were newly identified during this current assessment 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 Because the VPAs reported from last year's assessment remained unchanged in size and species composition when observed during this assessment, they will not be discussed in this memorandum, but all are included in the scoring of easement acreage performance categories in Table 6a, and are also summarized in Table 6b, Figure 2 (CCPV), and the VPA photolog Eighteen discrete areas of invasive species were documented throughout the site and totaled approximately 126 acres, or 7 4 percent of the total easement acreage (Table 6a) This resulted in 15 VPAs since three adjacent pairs of mapped polygons, exhibiting uniform Year 2 Site Assessment Report — South Muddy Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 5 of 6 invasive species compositions conditions, were combined into three individual VPAs Invasive species comprised approximately 0 29 acres more of the easement acreage area during this current visual assessment compared to last year's, or an increase of 1 7 percent in easement acreage area VPAs newly identified during this assessment (VPA2 -1 through VPA2 -7) were either composed of multiflora rose (Rosa multiflora), privet (Ligustrum smense), or Japanese honeysuckle (Lonicerajaponica), or a combination of those invasive species Multiflora rose and Japanese honeysuckle were the most prevalent invasive species observed within the VPAs and were found within six of the seven newly identified VPAs The 4 largest VPAs documented were VPA2 -2, VPA2 -6, VPA2 -1, and VPA2 -3 (in decreasing order by area) which are all located in the left terrace near the periphery of the easement boundary, these areas are susceptible to the encroachment of mvasives from outside the easement These 4 VPAs make up approximately 90 percent of the newly identified VPA acreage within the easement, VPA2 -4 is also located in the left terrace along the periphery of the easement boundary near the downstream side of the Sam Road bridge The persistence of invasive vegetation from within existing tree stands after prior treatment appears to be the other primary cause for the proliferation of invasive vegetation, and is the potential cause for VPA2 -5 and VPA2 -7 located in the left terrace downstream of the Sam Road bridge An existing tree stand is not apparent for VPA2 -5 on the CCPV in Figure 2, but it is situated around a power pole that was protected during construction and thus is surrounded by an undisturbed soil matrix likely containing intact roots and seeds of multiflora rose and Japanese honeysuckle As an update to additional areas of concern reported in the Year 1 Monitoring Report, there were no signs of kudzu in the left or right floodplains upstream of the Sam Road bridge, however, kudzu was observed outside the easement in those areas between the easement boundary and Sam Road Year 2 Site Assessment Report — South Muddy Creek North Carolina Ecosystem Enhancement Program Michael Baker Engineering, Inc May 31, 2013 Page 6 of 6 ----- cE--------- CE -
