The Site is located in Randolph County, approximately 11 miles southwest of the City of Asheboro, North Carolina. The Site is encompassed within a 129.2 -acre easement located in a 288 -acre tract owned by Amy Grissom. Historically, the downstream portion of the Site (west of Lassiter Mill Rd — SR 1107) was used for agriculture and livestock production. Livestock were removed and part of the land become fallow while the remainder is used for hay production or has been recently planted and burned by the North Carolina Wildlife Resources Commission ( NCWRC) as part of an ecosystem restoration initiative for the entire property. Prior livestock activity had compromised the riparian buffer along many of the project reaches. The upstream portion of the Site (east of Lassiter Mill Rd) is primarily forested. Riparian vegetation in this area is comprised mainly of mature deciduous trees. This report (compiled based on the NC Ecosystem Enhancement Program (NCEEP) Procedural Guidance and Content Requirements for EEP Monitoring Reports Version 1.4 dated 11/7/11) summarizes data for Year 3 (2014) monitoring. The project goals outlined in the approved Mill Creek Restoration Plan [NCEEP 2008] included the following. • Improve water quality within the Unnamed Tributary (UT) 2, UT 5, and Mill Creek watersheds by reducing sediment and nutrient inputs, increasing dissolved oxygen concentrations, improving stream stability, and wetland filtering. • Improve water quantity within the UT2, UT 5, and Mill Creek watersheds by improving ground water recharge, restoring hydrologic connections, and reconnecting channels with floodplains. • Improve aquatic and terrestrial habitat within the UT2, UT 5, and Mill Creek watersheds by improving substrate and in- stream cover, reducing water temperature by increasing shading, improving terrestrial habitat, and improving overall aesthetics. • Increase animal and vegetation biodiversity within the Site by connecting riparian buffer improvements associated with the NCEEP's Mill Creek project with a NCWRC native piedmont prairie grass restoration project located outside of the NCEEP's conservation easement boundaries. These goals were accomplished through the implementation of the following objectives as outlined in the Mill Creek Restoration Plan [NCEEP 2008]. • Permanently protect stream channels through a conservation easement. • Restore perennial stream channel. • Enhance perennial and intermittent stream channel. • Preserve perennial channel. • Create wetland. • Restore UT2 to its original drainage path to the Uwharrie River below the breached dam. • Create a new channel below UT5's breached dam that flows along the fall of the valley to reduce toe -of -slope erosion on the left bank Mill Creek (final) Axiom Environmental, Inc. Monitoring Year 3 of 5 (2014) EEP Project Number 253 October 2014 Randolph County, North Carolina page 1 • Improve floodplain functionality by matching the floodplain elevation with bankfull stage or by creating a bench to open the floodplain in areas where the channel is incised. • Establish native stream bank and floodplain vegetation in the permanent conservation easement. • Improve aquatic and riparian habitat by creating deeper pools and areas of re- aeration, planting a riparian buffer, and reducing bank erosion. During Year 3 (2014) monitoring eight vegetation plots were monitored. Vegetation from all eight plots averaged 369 planted stems - per -acre (excluding livestakes). Five of the eight plots met or exceeded the success criteria of 320 planted stems - per -acre (minimum stem count after 3 years). When including naturally recruited stems of appropriate species such as winged elm (Ulmus alata) and American elm (Ulmus americana) Plot 3 were well -above 320 stems - per -acre. Planted woody vegetation throughout the Site is somewhat sparse due to competition from herbaceous plants. Herbaceous vegetation has become more established along excavated benches; however, woody stems are still minimal. In the upstream portions of UT2 and UT4, sweetgum (Liquidambar styraciflua) saplings have established and are particularly dense. Two areas of concern were observed. These are described in the table below and are identified on Figures 2A and 2B (Appendix B). Vegetation Areas of Concern Map Identifier Feature/Issue Veg Area of Concern #1 Dense sweet gum (Liquidambar styraciflua) and blackberry (Rubus sp.) Stream Area of Concern #1 community outcompeting planted stems on the upstream portion of UT2 Veg Area of Concern #2 Dense sweet gum (Liquidambar styraciflua) population mostly between UT4 and Mill Creek Visual assessment and geomorphic surveys completed for the Site indicate that project reaches were performing within established success criteria ranges as shown below. No significant bank erosion was recorded, and geomorphic measurements are within the range of the design parameters. Two areas of concern were observed along stream monitoring reaches within the sites. The table below describes the issues and each area is identified on Figures 2A and 2B (Appendix B). Stream Areas of Concern Map Identifier Feature/Issue Cross vane at bottom of Mill Creek has been compromised due to high flows Stream Area of Concern #1 of the Uwharrie River. Structure is intact but adjacent banks have been eroded causing water to flow around arms and pipe underneath headers Sixth upstream cross vane in series of drop structures has failed completely, Stream Area of Concern #2 upstream and downstream structures are intact and functioning. Failure likely due to localized heavy rain event between June and September 2014. Mill Creek (final) Axiom Environmental, Inc. Monitoring Year 3 of 5 (2014) EEP Project Number 253 October 2014 Randolph County, North Carolina page 2 Stream Success Criteria (from approved Mill Creek Restoration Plan, Final Report [EEP 2008]): • Success is defined as little change in as -built cross - sections. If changes do take place they should 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. • Cross - sections shall be classified using the Rosgen Stream Classification System, and all monitored cross - sections should fall within the quantitative parameters defined for channels of the design stream type. • The longitudinal profiles should show that bedform features are remaining stable (i.e., they are not aggrading or degrading). Pools should remain deep with flat water surface slopes, and the riffles should remain steeper and shallower than the pools. Bedforms observed should be consistent with those observed for channels of the design stream type. • A minimum of two bankfull events must occur in separate years within the five -year monitoring. 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. 2.0 METHODOLOGY 2.1 Vegetation Assessment Eight vegetation plots were established and marked after construction with five -foot metal t -post demarking the corners with a ten -foot, three- quarter inch PVC at the origin. The plots are 10 meters square and are located randomly within the Site. These plots were surveyed in July for the year 3 (2014) monitoring season using the CVS -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 July for the year 3 (2014) monitoring season. 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). Mill Creek (final) Axiom Environmental, Inc. Monitoring Year 3 of 5 (2014) EEP Project Number 253 October 2014 Randolph County, North Carolina page 3 Eight permanent cross - sections, six riffle and two pool, were established and will be used to evaluate stream dimension; locations are depicted on Figures 2A -2B (Appendix B). Cross - sections are permanently monumented with 5 -foot metal t -posts at each end point. Cross - sections were 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 were used to calculate width -depth ratios, entrenchment ratios, and bank height ratios for each cross - section. In addition, pebble counts were completed at cross - sections 3 and 6, and photographs will be taken at each permanent cross - section annually. Three crest gauges are located within the Site monitoring reaches (on UT -2, UT -5, and Mill Creek within the lower, downstream one third of each reach). Crest gauges are PVC with granulated cork, mounted to a post driven into the channel. Crest gauges will be checked for overbank events during each monitoring visit. Three stream monitoring reaches were established and will be used to evaluate stream pattern and longitudinal profile; locations are depicted on Figures 2A -2B (Appendix B). Measurements 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, facet slopes, and pool -to -pool spacing. Thirteen permanent photo points were established throughout the restoration reach; locations are depicted on Figures 2A -2B (Appendix B). In addition, visual stream morphology stability assessments will be completed in each of the three monitoring reaches annually to assess the channel bed, banks, and in- stream structures. 3.0 REFERENCES Ecosystem Enhancement Program (EEP).

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. 2 = The acreage within the easement boundaries. 3 = 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. 4 = 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 red italics 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. % of Mapping CCPV Number of Combined Easement Vegetation Category Definitions Threshold Depiction Polygons Acreage Acreage 4.
