basin 04 -03 -07 The Site is located in Yancey County, approximately eight miles west of the City of Burnsville, North Carolina The Site is encompassed within a 12 74 -acre easement located on two tracts of property Tract one is owned by Henry and Elizabeth Turner and tract two is owned by Charles Young Jr and Deana Blanchard The Site is comprised of five headwater tributaries originating from Mountain seeps and springs, and five adjacent streamside wetlands (Figure 2, Appendix B) Prior to construction, upper reaches of the Site were forested and relatively stable Downstream reaches were impacted by agriculture activities with minimal riparian buffer This report (compiled based on the NC Ecosystem Enhancement Program (NCEEP) Procedural Guidance and Content Requirements for EEP Monitoring Reports Version 14 dated 11/7/11) summarizes data for Year 1 (2012) monitoring The project goals (from approved Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan [NC EEP 2009]) include the following • Reduce erosion from within the Site • Restore a channel capable of transporting watershed flows and sediment loads efficiently • Improve wetland and stream aquatic habitat • Enhance wildlife habitat • Improve overall water quality These goals will be accomplished through the implementation of the following objectives • Exclude livestock from the stream in order to • Reduce direct inputs of nutrients and fecal coliform bacteria into the stream • Eliminate the stress on streambanks caused by hoof shear • Plant a native riparian buffer in order to o Provide woody root mass to stabilize the streambanks o Filter sediment and nutrient pollutants from agricultural fields and prevent them from entering the stream J o Provide shade to the stream channel as a means of reducing water temperatures - o Provide a source for woody debris and leaf litter that will enhance aquatic habitat • Enhance existing wetlands by excluding livestock, managing invasive species, and plantmg native wetland vegetation _ • Restore Site streams to a proper bankfull dimension and stabilize steep and eroding streambanks • Provide Site streams with adequate flood -prone area • Repair headcuts and establish a more diverse bed morphology with rile -pool sequences _ supported by in- stream structures • Restore an impounded reach of stream by removing a small dam and culvert • Create protected riparian corridors for wildlife passage • Preserve high - quality forested headwater streams in the steeper reaches of the Site Ur to Bald Stream (Final) Axiom Environmental, Inc Momtonng Year 1 of 5 (2012) EEP Project Number 92596 February 2013 -- Yancey County, North Carolina page 1 Vegetation success criteria (from approved Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan [NC EEP 2009]) consists of the following "The success criteria for the preferred species in the restoration areas will be based on annual and cumulative survival and growth over five years Survival of preferred species must be at a minimum 320 stems - per -acre at the end of three years of monitoring and 260 stems - per -acre after five years " During Year 1 (2012), six vegetation plots were established and monitored Overall, Site vegetation averaged 358 stems - per -acre, which exceeds the minimum stem count for success criteria of 320 stems - per -acre Four of the six plots met or exceeded the success criteria Vegetation plots 2 and 4 were below success criteria with 243 stems - per -acre, each Low planted stem survival in vegetation plots 2 and 4 may be attributed to competition from herbaceous vegetation (primarily fescue [Festuca spp ] and tearthumb [Polygonum spp ]) In addition, one problem area of easement encroachment has been identified adjacent to Tributary 2 (Figure 2) This area has been mowed to the stream edge, with piles of brush dumped adjacent to the creek Stream success criteria (from approved Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan [ NCEEP 2009])]) consists of the following "Monitoring shall consist of the collection and analysis of stream stability and riparian vegetation survivability data to support the evaluation of the project in meeting established restoration objectives " A visual assessment and geomorphic survey were completed for the Site It is too early in the 5- year annual monitoring period for Site measurements to determine if stream success criteria, in - relation to restoration objectives, are being achieved However, Site reaches are conforming to design criteria established in the Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan ( NCEEP 2009) No significant bank erosion was recorded and geomorphic measurements are within the range of the proposed design parameters Stream I channels appear to be exhibiting aggradation of fine materials, possibly from surface flows across the adjacent floodplain and extensive herbaceous vegetation growth within the channel bed Currently, aggradation does not appear to present a problem, however, continued observation throughout the monitoring period should determine if the system is able to flush aggraded material 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 tables and figures within this report's 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 the Restoration Plan) documents available on NCEEPs website All raw data supporting the tables and figures in the appendices is available from NCEEP upon request UT to Bald Stream (Final) Axiom Environmental, Ina Monitoring Year 1 of 5 (2012) EEP Project Number 92596 February 2013 Yancey County, North Carolina page 2 2.0 METHODOLOGY 2.1 Vegetation Assessment Six vegetation plots were established and marked during the Year 1 (2012) monitoring period Plots were established by installing 4 -foot, metal U -bar post at the corners and a 10 -foot, 0 75 inch PVC at the ongin The plots are 10 meters square and are located randomly within the Site These plots were surveyed in December for the Year 1 (2012) monitoring season using methods outlined in CTS -EEP Protocol for Recording Vegetation, Levels 1 -2 Plot Sampling Only, Version 4 2 (Lee et al 2008) (http //cvs bio unc edu /methods htm), results are included in Appendix C The taxonomic standard for vegetation used for this document was Flora of the Southern and Mid- Atlantic States (Weakley 2012) 2.2 Stream Assessment Annual stream monitoring was conducted in December of 2012 with additional supplementary measurements conducted in February of 2013 Measurements were taken using a Topcon GTS 303 total station and Recon data collector The raw total station file was processed using Carlson Survey Software into a Computer Aided Design (CAD) file Coordinates were exported as a text /ASCII file to Microsoft Excel for processing and presentation of data Pebble counts were completed using the modified Wolman method (Rosgen 1993) One crest gauge (PVC with wooden staff gauge and cork filings) was installed in the lower, downstream third of the Site Annual stream monitoring was conducted in December 2012 and February 2013 Six permanent cross - sections, three riffle and three pool, were established and will be used to evaluate stream dimension, locations are depicted on Figure 2 (Appendix B) Cross - sections are permanently monumented with 5 -foot metal t -posts at each end point Cross - sections will be surveyed to provide a detailed measurement of the stream and banks including points on the adjacent floodplain, top of bank, bankfull, breaks in slope, edge of water, and thalweg Data will be used to calculate width -depth ratios, entrenchment ratios, and bank height ratios for each cross - section In addition, a pebble count was completed at cross - section 2 and photographs will be taken at each permanent cross - section location annually Six stream monitoring reaches were established and will be used to evaluate stream pattern and longitudinal profile, locations are depicted on Figure 2 (Appendix B) Measurement of channel - pattern will include belt - width, meander length, and radius of curvature (only in year one) Subsequently, data will be used to calculate meander -width ratios Longitudinal profile measurements will include average water surface slopes and facet slopes and pool -to -pool spacing Twenty two permanent photo points were established throughout the restoration reach (12 fixed photo points, 4 cross - section photo points, and 6 vegetation plot photo points), locations are depicted on Figure 2 (Appendix B) and are included in Appendix B In addition, visual stream morphology stability assessments will be completed in four monitoring reaches annually to assess the channel bed, banks, and in- stream structures UT to Bald Stream (Final) Axiom Environmental, Ina Monrtonng Year 1 of 5 (2012) EEP Project Number 92596 February 2013 Yancey County, North Carolina page 3 3.0 REFERENCES Ecosystem Enhancement Program (EEP) Unpublished Procedural Guidance and Content Requirements for EEP Monitoring Projects, Version 14, dated 11/07/11 NC Department of Environment and Natural Resources Available online at http //portal ncdenr org/c/ document_ library/get_ file ?p_1_id = 1169848 &folderld = 2288101 &name =DLFE -39268 pdf Lee, MT, R K Peet, SD Roberts, and T R Wentworth 2008 CVS -EEP Protocol for Recording Vegetation, Levels 1 -2 Plot Sampling Only, Version 4 2 Available online at http / /cvs bio unc edu /methods him N C Ecosystem Enhancement Program 2009 Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan -

This number is calculated as the easement acreage minus any existing mature tree stands that were not subject to supplemental planting of the understory, the channel' acreage, crossings or any other elements not directly planted as part of the project effort. = The acreage within the easement boundaries = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event a polygon is cataloged into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant item (i.e., item 1,2 or 3) as well as a parallel tally in item 5. = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement acreage. Invasives of concern /interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native, young, woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established tree /shrub stands over timeframes that are slightly longer (e.g. 1 -2 decades). The low /moderate concern group are those species that generally do not have this capacity over the timeframes discussed and therefore are not expected to be mapped with regularity, but can be mapped, if in the judgement of the observer their coverage, density or distribution is suppressing the viability, density, or growth of planted woody stems. Decisions as to whether remediation will be needed are based on the integration of risk factors by EEP such as species present, their coverage, distribution relative to native biomass, and the practicality of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the projects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not likley trigger control because of the limited capacities to impact tree /shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground cover. Those species with the 'Watch list' designator in gray shade are of interest as well, but have yet to be observed across the state with any frequency. Those in are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mapped as polygons, The symbology scheme below was one that was found to be helpful for symbolzing invasives polygons, particulalry for situations where the conditon for an area is somewhere between isolated specimens and dense, discreet patches. In any case, the point or polygon /area feature can be symbolized to describe things like high or low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the narrative section of the executive summary.
