1.0 EXECUTIVE SUMMARY
The UT to Bald Creek Stream and Wetland Restoration Site (hereafter referred to as the "Site ")
is situated within the US Geological Survey (USGS) hydrologic unit 06010108 of the French
Broad River Basin and is in a portion of NC Division of Water Quality (NCDWQ) Priority Sub -
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 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 2 (2013) monitoring.
The project goals (from approved Unnamed Tributaries to Bald Creek Stream Restoration
Project, Final Restoration Plan [NCEEP 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
• Provide woody root mass to stabilize the streambanks
• Filter sediment and nutrient pollutants from agricultural fields and prevent them
from entering the stream
• Provide shade to the stream channel as a means of reducing water temperatures
• 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

Vegetation success criteria (from approved Unnamed Tributaries to Bald Creek Stream
Restoration Project, Final Restoration Plan [NC EEP 2009]) is as follows.
"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."
Six vegetation monitoring plots were monitored on August 12, 2013 for monitoring year 2
(2013). Overall, Site vegetation averaged 425 planted stems - per -acre (excluding livestakes) in
year 2 (2013), which exceeds the minimum stem count for success criteria of 320 stems - per -acre.
Five of the six plots met or exceeded the success criteria. Vegetation plot 4 was below success
criteria with 202 planted stems - per -acre. Low planted stem survival in vegetation plot 4 may be
attributed to competition from herbaceous vegetation (primarily fescue [Festuca spp.] and
tearthumb [Polygonum spp.]).
Five vegetation areas of concern were identified on the site. Planted stem density was moderate
to poor throughout the site. Planted stems in the drier portions of the site were generally hard to
locate due to the thick fescue. Wetter areas in the site had poor stem growth due to saturation
and competition with sedges and soft rush (Carex spp. and Juncus effusus). Additionally, three
small patches of multiflora rose (Rosa multiflora) were identified in the site. These areas of
concern are summarized below and depicted on the attached Figure 2 (Appendix B).

Stream success criteria (from approved Unnamed Tributaries to Bald Creek Stream Restoration
Project, Final Restoration Plan [NCEEP 2009])]) consists 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."
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 a headcut on Tributary 2 that currently poses no immediate
threat to stream stability. In addition, five areas of aggradation (SAC -2 to 6) were observed
along the mainstem, Tributary 2, and Tributary 4. These areas were documented previously and
conditions have improved since last reported in the year 1 (2012) monitoring report. Stream

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. Stream areas of concern are summarized in the following table and are
depicted on Figure 2 (Appendix B).

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 origin. The plots are 10 meters square and are located randomly within the Site.
These plots were surveyed in August for the Year 2 (2013) 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 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.
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.

2 = Entrenchment Class - Assign /bin the reach footage into the classes indicated and provide the percentage of the total reach footage in each class in the table. This will result from the measured cross - sections as well as visual estimates
3 = Assign /bin the reach footage into the classes indicated and provide the percentage of the total reach footage in each class in the table. 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 Feld 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.

If the performer has inherited the project and cannot acquire the datum for prior years this must be discussed with EEP. If this cannot be resolved in time for a given years report submission a footnote in this should be included that states: "It is uncertain if the monitoring datum has been
consistent over the monitoring history, which may influence calculated values.
Additional data from a prior performer is being acquired to provide confirmation. Values will be recalculated in a future submission based on a consistent datum if determined to be necessary."
