Introduction
Stream impacts to an unnamed tributary to South Fork Withrow Creek, a Class C water, were
results of both direct and indirect impacts leading to the issuance of a Notice of Violation from
the U.S. Army Corps of Engineers dated August 24, 2016. A combination of excessive storm
flow directed to the stream and construction of an impoundment located on the unnamed
tributary created a system characterized by extremely flashy and erosive flows at discharges
causing instability. The excessive flows resulted in rapid down -cutting of the stream bed and
vertical banks forming gully -like stream conditions with no floodplain access. The mobilized
sediment in the upper reaches impacted lower reaches burying stream features, aiding storm
flows at discharges exceeding natural flow, restricting aquatic life mobility, and creating a loss of
habitat. The stream restoration objectives focused on providing a natural system that was able to
efficiently transport sediment, provide for aquatic life mobility, and restore the stream
morphology (pattern, profile, and dimensions) for both temporal and morphological stability.
Restoration and Construction Summary
Stream restoration construction activities on site conducted by South Fork Mooresville LLC and
Atlas Environmental, Inc. began on April 10, 2017 and were concluded on July 12, 2017.
Originally a total of 16 grade control and habitat forming structures were installed along the
1,621 linear feet of stream from the toe of the slope at the upstream reach to the approximate
location of the removed storm water best management practice dam. No grade control structures
were installed along the section of stream downstream from the existing sewer line due channel
migration being restricted by existing bedrock. In -stream structures consisted primarily of log
vanes and steps with rock structures installed in locations where extra stability was required.
There are a total of 9 log structures (log vanes and steps) and 7 large rock structures 0 -hooks and
cross vanes). Two additional log steps were installed on May 8 and 9, 2018 to reduce the relative
elevation change between structures, increase aquatic life passage, and minimize changes of
being undercut by erosive storm flows. Storm water control devices, Aqua -Shield units, were
installed to treat storm water runoff by removing total suspended solids. The main Aqua -Shield
unit sends treated water to the stream via a level spreader through a single 24 -inch pipe and the
remainder of the water, from large storm events, is culverted to the dry detention basin through a
48 -inch pipe. The water moves through the forebay separated from the main area of the pond by
riprap and gravel to an outlet that directs the water treated by settling back to the stream at a
downstream location at the end of the stream restoration reach. The Aqua -Shield systems allow
for a reduction in the amount of storm water that is being directed to the stream. The level
spreader system that discharges treated water to the stream consists of a level 24 -inch corrugated
metal pipe with approximately 100 two inch holes torched into the pipe at varying elevations.
The holes control the discharge stabilizing the stream system by creating a more natural
hydrograph. The storm water flows through a bio -engineered wetland for additional settling and
slowing of the flow before entering a widened section of the stream.

Morphology/Hydrology
Field work for the 2018 "Stream Restoration Annual Monitoring Report" was completed in May and June
2018. All measurements of dimension, pattern, and profile were collected using a Nikon Pulse Laser Station
NPL -332. A total of 12 cross sections, a longitudinal profile, and a pattern map were produced from the
collected data and analyzed using RIVERMorph Professional 5.1. Select data was also imported into GIS
applications for additional analysis and for quality checking the data. The drainage basin of the reach was
measured to be 0.081 square miles by GIS applications. Basin topographic relief is 98 feet and stream
topographic relief is 26.5 feet. Bankfull discharge of the stream was determined to be between 5.62 CFS and
5.93 CFS using Manning's Roughness and Friction Factor/Relative Roughness, respectively.
Dimension
Channel geometry was characteristic of a first order perennial stream located in the piedmont of North
Carolina consisting of cohesive banks. Of the 12 cross sections collected 5 were located at riffles, 4 were
located at glides, one was located at a pool, one was located at a run, and one was listed as being located at
other. The cross section listed as "other" is cross section 1 and is in a highly vegetated section with wetland
vegetation along both banks. Features relating to a specific bed form were absent and this cross section was
not used in the calculation of dimension ratios. The cross section that was used for calculation of roughness
and discharge calculation is cross section 9. This cross section is an average representation of the entire reach
and is along the lower third but is upstream of the dry detention basin discharge. The stream in the area of the
dry detention discharge was armored with boulders to dissipate energy and protect the banks. Downstream of
this point the stream is bedrock controlled. The average bankf ill Width to Depth ratio of the riffles is 16.8
with an average width at bank full of 5.39 feet and depth of 0.49 feet. The average flood -prone width area is
10.6 giving an entrenchment ratio of 2.07 which falls between moderately and slightly entrenched. The
stream is capable of reaching the floodplain during high flow events. This metric is essential at the South
Fork site due to the flashy nature caused from storm water. If there is no access to the floodplain the stream
would begin to down -cut from a C -stream to a G -stream and over widen to an F -stream leading to high
sediment mobility. Cross section dimension of the riffle sections shows a decrease in bankfull width to depth
ratio with bar building occurring along the stream edges and defined streams forming with an inner berm and
bankfull bench.

Horizontal Oislanos [ft]
A comparison of cross section 9, a riffle, at station 8+31 clearly shows a bar building along the left bankfull
indicator, an inner berm, and deepening of the main channel that is creating a low flow area to efficiently
transport sediment at a variety of flow conditions.
Pattern
The pattern of the stream is slightly sinuous exhibiting limited lateral migration due to the highly cohesive,
high clay content, banks. Measured channel geometry averages have a linear wavelength of 107 feet,
meander length of 125 feet, and a radius of curvature of 17-20 feet. The sinuosity of the reach was calculated
by stream length/valley length to be 1.12. This sinuosity is slightly less than that of a typical C -stream. It is
likely that future monitoring reports will indicate a belt width becoming wider and sinuosity increasing closer
to a 1.2. The dimensionless ratios are appropriate and show little change from the 2017 As -Built report.
Profile
The channel profile was collected along the thalweg of the stream with an emphasis on collecting points
around areas of large elevation changes and constructed grade control structures. Due to the restoration reach
beginning at the head of the basin a variety of slopes are displayed ranging from steeper at the upper most
section to flatter near the confluence with South Fork Withrow Creek. The upper third of the longitudinal
profile exhibits slopes that approximate 4.2-4.5% up to structure number 3 that is immediately upstream of the
constructed wetland. Stream slopes through the middle and lower sections of the reach range from 1.3-1.5%
to the area of bedrock control that begins immediately downstream of the existing aerial sewer line crossing.
Biological
Monitoring of biological indices includes the establishment of six, randomly selected, vegetation plots. The vegetation
plots are 10 foot X 10 foot squares which are marked by white PVC pipe and orange paint. Live stakes were harvested
and planted from existing vegetation during construction along with the planting of 2000 live stakes on December 5 and 6,
2017. Live stake species that were planted included Elderberry, Black Willow, Silky Willow, and Silky Dogwood. There
were 500 live stakes planted of each species. In addition to vegetation monitoring Atlas has conducted general surveys
for aquatic life including fishes, amphibians, crustaceans, reptiles, and macro -invertebrates over the past year.

Aquatic Life Survey
During the monitoring report fieldwork Atlas staff assessed a variety of riffles and pools throughout the
restoration reach in a qualitative effort to assess the rebound of aquatic life for environmental uplift. During
the survey all species in the "Observed Aquatic Life" table were visually documented within the restoration
reach. There are significantly greater varieties and numbers of macro -invertebrates and fish than what existed
prior to restoration. The majority of fish were observed in deep pools along the middle and downstream
sections of the restoration reach and appear to be creek chubs. Indicators of higher stream quality (EPT taxa)
were observed in higher numbers through the upper third of the reach that receives less flow and where the
bed has higher quantities of detritus and shade. The upper section also receives direct inflow of groundwater
at cooler temperatures than downstream areas providing for higher dissolved oxygen concentrations. It is
expected that the lower reaches will begin to attract higher quality EPT taxa in the future. Reptiles and
amphibians have also been observed throughout the entire reach but were not observed during the monitoring
report and are denoted in the table with an asterisk.

Log Vane — Structure 16
Structure 16 is a non -preforming grade control structure. After installation repairs to this structure have included adding a
coir log and thicker fabric in upstream of the structure to prevent the stream bed from undercutting under the log. The
black fabric was nailed to the log then buried under the stream bed upstream for approximately 8 feet. A "V" notch was
cut into the center of the log to allow base flow to flow over the log during normal flow instead of around or under the
structure. This fixes have allowed structure 16 to remain stable since the last adjustments.

Conclusion
The extent of the stream restoration project at South Fork Business Park appears to be in good and stable
condition. Changes have been observed between the 2017 As -Built Report and the 2018 Annual Monitoring
Report that are indicating creation of a more defined stream. Observed changes through the restoration reach
include bar building and creation of inner berms as a result of large, relatively short duration, storm events.
These changes narrow the channel for low flow periods and allow for more efficient sediment transport during
both high and low flow periods from down welling along the point bars. The constructed wetland between
cross sections 3 and 4 dramatically reduces the immediate impact of storm events on the restoration reach.
The wetland is now vegetated with thick wetland herbs and the live stakes. The Willows have had an
especially high survival rate. The additional storage and limited discharge of treated storm water are essential
for the health and stability of the system downstream. Select banks and log steps are becoming undercut due
to pool development. These features provide great habitat and refuge from both high flow events and
predators. Raccoon prints have been observed along the entire reach specifically located around the large
pools. Observed fish typically range from one inch up to four inches and are located in large pools from the
wetland to the confluence with South Fork Withrow Creek.
Indicators of incision, such as a low bank above a bankfull indicator, have not been observed. Predicted
changes from 2018 to 2019 would be for cross section 3, downstream to the large j -hook to become narrower
and experience bar building events along the right bank. The channel is currently U-shaped with very shallow
water which is causing slight deposition and bank water. This area was constructed with a wide W/D ratio to
handle the large flows from the wetland. However, a slight narrowing of the channel may prevent emergence
of wetland vegetation.
Due to site conditions multiple bankfull discharge have been observed on various occasions in the last year.
The high frequency of bankfull discharges lead to structures in the lower reach not preforming as designed and
required the addition of two log steps. These steps were placed above and below the last structure that was
proposed in the restoration plan. The addition of the two log steps reduced the elevation change per step and
will minimize future chances of being undercut in the future. Log step installation procedures were also
amended to include a low flow notch in the log for pool development and sediment transport, a coir log buried
upstream of the step for added re -enforcement, and installation of thick matting nailed to the structure and
buried upstream of the structure to prevent downcutting of the stream bed.

Channel Materials (Particle Size Index ) D50
The D5D particle size index represents the mean diameter of channel materials, as
sampled from the channel surface, between the bankfull stage and Thalweg
elevations_ 16.18
Water Surface SLOPE (S)
Channel slope = "rise over run" for a reach approximately 20-30 bankfull channel
widths in length, with the 'riff le-to-rifHe" water surface slope representing the gradient
at bankfull stage. 0,4148
Channel SINUOSITY (k}
Sinuosity is an index of channel pattern, determined from a ratio of stream length
divided by valley length (SL f VL); or estimated from a ratio of valley slope divided by
