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 agricultural activities with minimal riparian buffer. This report (compiled based on the North Carolina Ecosystem Enhancement Program (NCEEP) Procedural Guidance and Content Requirements for EEP Monitoring Reports Version 1.4 dated 11/7/11) summarizes data for Year 5 (2016) monitoring. The project goals (from the approved Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan [NCEEP 2009]) include the following. • Reduce erosion 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 o Reduce direct inputs of nutrients and fecal coliform bacteria into the stream o Eliminate 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 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 planting 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 riffle -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 UT to Bald Stream (final) Axiom Environmental, Inc. Monitoring Year 5 of 5 (2016) DMS Project Number 92596 December 2016 Yancey County, North Carolina page 1 Vegetation success criteria (from the approved Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan [NCEEP 2009]) is as follows. "Success criteria for the preferred species in restoration areas will be based on annual and cumulative survival and growth over five years. Survival of preferred species must be at a minimum of 320 stems -per -acre at the end of three years of monitoring and 260 stems -per - acre after five years." Six vegetation monitoring plots were monitored on September 2016 for monitoring Year 5 (2016). Overall, Site vegetation averaged 384 planted stems -per -acre (excluding livestakes) in Year 5 (2016), which exceeds the minimum stem count for success criteria of 260 stems -per -acre. Four of the six plots met or exceeded success criteria. Vegetation plots 4 and 5 were below success criteria with 243 planted stems -per -acre each, just one stem shy of success criteria. Low planted stem survival in vegetation plots 4 and 5 may be attributed to competition from herbaceous vegetation (primarily fescue [Festuca spp.] and tearthumb [Polygonum sagitatum]). Thirteen vegetation areas of concern were identified on the site. Planted stem densities were moderate throughout the Site and are low in certain areas (VAC -1 to -4). Planted stems were generally hard to locate due to the thick fescue (Festuca spp.) in drier areas and had poor stem growth due to saturation and competition with sedges (Carex spp.), soft rush (Juncus effusus), and tearthumb (Polygonum sagitatum) in wetter areas. Multiflora rose (Rosa multiflora) was observed scattered throughout the site, however seven small patches of very dense multiflora rose (Rosa multiflora) were identified during Year 5 (2016). A treatment was performed in October 2016 which greatly reduced the density of these populations, however, these patches still appear to be negatively affecting planted stem survivability. Additionally, two patches of dense white poplar (Populus alba) were identified on the Site. These areas of concern are summarized below and depicted on the attached Figure 2 (Appendix B). Vegetation Areas of Concern Map Identifier Feature/Issue VAC -1 Low stem density around Tributary 3 VAC -2 Low stem density on the right bank of the Mainstem in and around Veg Plot 5 VAC -3 Low stem density in and around Veg Plot 4 VAC -4 Low stem density on the right bank of Tributary 2 near an adjacent driveway VAC -5 to -11 Multiflora rose VAC -12 to -13 Dense white poplar Stream success criteria (from the approved Unnamed Tributaries to Bald Creek Stream Restoration Project, Final Restoration Plan [NCEEP 2009]) is as follows. "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." UT to Bald Stream (final) Axiom Environmental, Inc. Monitoring Year 5 of 5 (2016) DMS Project Number 92596 December 2016 Yancey County, North Carolina page 2 A visual assessment and geomorphic survey were completed for the Site. 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 proposed design parameters. Stream areas of concern include five areas of aggradation (SAC -1 to -5) were observed along the Mainstem, Tributary 2, Tributary 3, and Tributary 4. Several of these areas were documented previously and conditions continue to improve. During Year 3 (2014) monitoring, it was noted that the upper reaches of Tributary 3 and Tributary 4 have indiscernible bed and bank for varying lengths. These tributaries exhibit intermittent flow regimes, and low flow may be responsible for the lack of bed and bank characteristics in these reaches. These areas remained unchanged during Year 4 (2015) and Year 5 (2016) monitoring. The middle reach of the Mainstem, just below the pond, and the lower reach of Tributary 2 appear to be exhibiting aggradation of fine materials, possibly due to surface flows across the adjacent floodplain and extensive herbaceous vegetation growth within the channel bed combined with low energy flow in the channel. Additionally, a failed structure was observed in the downstream reach of Tributary 3, just before its confluence with the Mainstem. Several boulders from the bank of this long step -pool, fallout structure have fallen into the streambed. The structure appears relatively stable with herbaceous vegetation establishing on the dislodged boulders, however it is not yet completely stabilized. Stream areas of concern are summarized in the following table and are depicted on Figure 2 (Appendix B). Stream Areas of Concern Map Identifier Feature/Issue SAC -1 and -2 Aggradation on Mainstem SAC -3 Aggradation on the lower portion of Tributary 2 SAC -4 and -5 Indiscernible bed and bank on the upper reaches of Tributaries 3 and 4 SAC -6 Failed rock structure on Tributary 3 The stream reach adjacent to cross-section 2 exhibited significant down cutting during years 3 (2014) and 4 (2015). During early summer 2016, a headcut was observed rapidly migrating upstream through this area creating significant incision below it, damaging a log structure. In October 2016, NCDMS performed stream repairs in order to repair the structure and return the streambed to its design elevation. This repair is depicted in the Cross Section 2 plot (Appendix D). A previously observed headcut and resulting incision in the lower portion of Tributary 2 was also repaired at that time. Some down cutting was also observed at cross-section 3 during year 5 (2016); however, this was the result of an isolated high-energy flow, and it does not pose any threat to stream stability or Site success. 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 NCDMS's website. All raw data supporting the tables and figures in the appendices is available from NCDMS upon request. UT to Bald Stream (final) Axiom Environmental, Inc.

Plots were established by installing 4 -foot, metal U -bar posts at the corners and a 10 -foot, 0.75 inch PVC at the origin. The plots are 10 meters square and are located randomly within the Site. These plots were surveyed in September 2016 for the Year 5 (2016) monitoring season using methods outlined in 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 April 2016. 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. Six permanent cross-sections, three riffle and three pool, were established and will be used to evaluate stream dimension annually; 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.

This will result from the measured cross-sections as well as the longitudinal profile Footnotes 2,3 - These classes are loosley built around the Rosgen classification and hazard ranking breaks, but were adjusted slightly to make for easier assignment to somewhat coarser bins based on visual estimates in the field such that measurement of every segment for ER would not be necessary. The intent here is to provide the reader/consumer of design and monitoring information with a good general sense of the extent of hydrologic containment in the pre-existing and the rehabilitated states as well as comparisons to the reference distributions. ER and BHR have been addressed in prior submissions as a subsample (cross-sections as part of the design survey), however, these subsamples have often focused entirely on facilitating design without providing a thorough pre-constrution distribution of these parameters, leaving the reader/consumer with a sample that is weighted heavily on the stable sections of the reach. This means that the distributions for these parameters should include data from both the cross-section surveys and the longitudinal profile and in the case of ER, visual estimates. For example, the typical longitudinal profile permits sampling of the BHR at riffles beyond those subject to cross-sections and therefore can be readily integrated and provide a more complete sample distribution for these parameters, thereby providing the distribution/coverage necessary to provide meaningful comparisons.
