June's Branch NCEEP Mitigation Plan June 2012

EXECUTIVE SUMMARY
Environmental Banc & Exchange (EBX) proposes to restore and enhance four unstable stream reaches in
central Jackson County. The Junes Branch Stream Restoration Site is located approximately 2 miles east
of Sylva, North Carolina at the latitude 35.357378° N and longitude 83.191391° W. The Site
encompasses approximately 5.7 acres of agricultural land and consists of four unstable streams:
Bumgarner Branch, Junes Branch, Higdon Branch, and Doris Branch. This mitigation plan describes the
details, methods and protocols proposed to generate approximately 3,076 stream mitigation credits,
which includes approximately 3,076 linear feet of stream restoration through Priority I restoration.
General Site Conditions
Historic land use at the Site has consisted primarily of agriculture and livestock grazing. Additional land
use practices, including the maintenance and removal of riparian vegetation and the relocating, dredging,
and straightening of on -site streams have contributed to unstable channel characteristics and degraded
water quality. Spoil piles have been observed on -site indicating that historic wetlands were likely drained
in order to maximize agricultural production.
Current stream conditions at the Junes Branch Stream Restoration Site contain incised channels with
unstable banks and a riparian buffer dominated by invasive exotic plants. Bumgarner Branch east of
Fairview Road flows through an active pasture with livestock access to the stream. The riparian buffer is
dominated by invasive exotic plants and the channel exhibits eroding stream banks contributing fine
sediment to the channel substrate. The downstream portion of Bumgarner Branch west of Fairview Road
is incised with actively eroding stream banks. Junes Branch, Higdon Branch, and Doris Branch contain
abundant invasive exotic plants within the riparian buffer and are also comprised of incised channels with
eroding stream banks. The adjacent land use along Junes Branch and the downstream portion of
Bumgarner is no longer active pasture and currently consists of fallow fields and hay production fields.
Restoration Concept
Restoration and enhancement practices proposed for this project have been designed with the intent to
minimize unnecessary disturbance to adjacent land. Professional judgment has been used to determine
which channel reaches could potentially benefit most from preservation or enhancement over full
restoration. Where restoration was determined to be warranted, consideration was given to which reaches
could best be served by maintaining as much of the existing channel pattern as possible.
Proposed Bumgarner Branch, Junes Branch, Higdon Branch and Doris branch are designed as Type B4
streams. These channel configurations provide a stable and natural form in the Type II colluvial valleys
in which the existing streams are found. The proposed channel dimensions, patterns, and profiles are
based on hydraulic relationships and morphologic dimensionless ratios of the reference reaches.
The installation of brush, rock, and wood structures will be utilized throughout the restored reaches of the
Site. Brush toe structures will be installed on selected meander bends to provide bank stability and
aquatic habitat. Boulder structures will be used for grade control to prevent headcut formation and to
provide step -pool bed form on steeper channel reaches. Log vanes with rootwads will be installed in
meander bends to direct the flow away from the outside of the bend and provide toe and bank protection.
On -site material including brush, boulders, logs, and bed material will be used to the maximum extent
possible and in- stream structures will be designed to improve aquatic habitat.

June's Branch NCEEP Mitigation Plan June 2012

1.0 RESTORATION PROJECT GOALS AND OBJECTIVES
EEP develops River Basin Restoration Priorities (RBRP) to guide its restoration activities within each of
the state's 54 cataloging units. RBRPs delineate specific watersheds that exhibit both the need and
opportunity for wetland, stream and riparian buffer restoration. These watersheds are called Targeted
Local Watersheds (TLWs) and receive priority for EEP planning and restoration project funds.
The 2008 Little Tennessee River Basin RBRP identified HUC 06010203020010 as a Targeted Local
Watershed http: / /www.nceep.net /services /lwps/ Little _Tennessee /RBRP_LTN_2008.pdf. Only 44% of the
stream length within this watershed has adequate buffers.
The 2008 Little Tennessee River Basin RBRP identified fecal coliform and turbidity as major stressors
within this TLW. The Junes Branch Project was identified as a stream restoration opportunity to improve
water quality and habitat within the TLW.
The project goals address stressors identified in the TLW and include the following
Improve water quality within the restored channel reaches and downstream watercourses
through:
• reducing turbidity by stabilizing existing stream banks and altering stream channel
dimension, pattern and profile
• reducing nutrient loads and fecal coliform bacteria from adjacent agricultural fields
by fencing the riparian area to keep livestock out of the stream and restoring a
wooded riparian buffer
Improve local aquatic and terrestrial habitat and diversity within the restored channels and
their vicinity through:
• reducing water temperatures by planting native vegetation in the riparian zone and
creating shade
• improving habitat complexity by restoring the stream profile to stable riffle /pool
complex and step /pool complexes
• improving terrestrial habitat by excluding livestock and creating a native riparian
buffer
• improving aquatic habitat by establishing tree canopy to provide organic material
such as woody debris and leaf packs to stream
• removing invasive exotic species and planting native vegetation in the riparian buffer
Improve flood flow attenuation on -site and downstream through:
o raising the bed or creating bankfull benches to allow for overbank flows every 1 -2
years and will improve the connection to the active floodplain
The project goals will be addressed through the following project objectives:
• Restore stable channel morphology and proper sediment transport capacity.
• Create and improve stream bed form and improve aquatic and benthic macroinvertebrate habitat.
• Reconnect the stream to the historic floodplain or construct a floodplain bench that is accessible
at the proposed bankfull channel elevation.
• Improve channel and stream bank stabilization by integrating in- stream structures and native bank
vegetation.
Provide riparian buffer restoration by establishing a native forested and herbaceous riparian
buffer plant community with a minimum width of 30 feet from the edge of the restored channels.
This new community will be established in conjunction with the eradication of any existing exotic
or undesirable plant species.
June's Branch NCEEP Mitigation Plan June 2012

2.0 SITE SELECTION
2.1 Directions to Site
The Junes Branch Stream Restoration Site (the Site) is located in central Jackson County approximately 2
miles east of Sylva, NC. From Asheville, take I -40 West for approximately 18 miles. Take exit 27 onto
US -74 toward US -19 /Clyde /US- 23/Waynesville. Take exit 107 toward Jones Cove Road and merge onto
US -23 South /US -74 West. After approximately 20 miles, take exit 85 toward NC- 107 /Cullowhee. Keep
right at the fork in the ramp and continue onto US -23 /Asheville Highway. Make a slight left onto NC-
107 /East Main Street for approximately 2 miles before turning left onto Fairview Road (SR 1724). The
Site begins at latitude 35.355166° N and longitude 83.192067° W.
2.2 Site Selection
2.2.1 Description
The Site encompasses approximately 5.7 acres of predominately agricultural land and includes a portion
of Bumgarner Branch, and three unnamed tributaries that for the purposes of this project are called
Junes Branch, Higdon Branch and Doris Branch. (See Figure 4).
Historic land use at the Site has consisted primarily of agriculture and livestock grazing. Additional land
use practices, including the maintenance and removal of riparian vegetation and the relocating, dredging,
and straightening of on -site streams have contributed to unstable channel characteristics and degraded
water quality. Spoil piles have also been observed on -site which indicates that historic wetlands were
likely drained in order to maximize agricultural production.
2.2.2 USGS Hydrologic Unit Code and NCDWQ River Basin Designations
The Junes Branch Site is located within the Little Tennessee River Basin, United States Geological
Survey (USGS) 14 -digit Hydrologic Unit 06010203020010, and the North Carolina Division of Water
Quality (NCDWQ) sub basin 04- 04 -02. Bumgarner Branch has been assigned the Stream Index Number
2- 79 -35 -1 by NCDWQ and is designated as Class C surface water. Tributaries to Bumgarner Branch
have not been indexed, but are also designated as Class C surface waters.
Class C waters are protected for uses such as secondary recreation, fishing, wildlife, fish consumption,
aquatic life including propagation, survival and maintenance of biological integrity, and agriculture.
Secondary recreation includes wading, boating, and other uses involving human body contact with water
where such activities take place in an infrequent, unorganized, or incidental manner (NCDWQ).
Bumgarner Branch flows into Mill Creek approximately 0.5 miles downstream of the Site which is also
assigned Class C use support designation. Mill Creek drains into the Tuckasegee River another 1.5 miles
downstream. This section of the Tuckasegee River has been assigned Class B; Tr. Class B waters are
protected for primary recreation activities such as swimming, skin diving, water skiing and similar uses
involving human body contact with water where such activities take place in an organized manner or on a
frequent basis (NCDWQ). These waters are also protected for Class C uses. The designation Tr (Trout
Waters) includes areas protected for natural trout propagation and survival of stocked trout.
2.2.3 Watershed Characterization
The Site watershed is characteristic of the Blue Ridge region with moderate rainfall with annual
precipitation averaging 52.9 inches. Elevations within the Site range from 2,200 ft. at the northwestern
June's Branch NCEEP Mitigation Plan June 2012

extent to 2,150 ft. along Junes Branch. The Site encompasses approximately 3,007 linear feet of streams
including Bumgarner Branch, Junes Branch, Higdon Branch and Doris Branch.
The drainage area of Bumgarner Branch at the downstream end of the Site is 1.03 miZ (668 acres). Land
use within the watershed consists of 68% forest, 21% low- density residential and 11% agricultural land.
Impervious area covers less than 1% of the total watershed. Land use changes are not anticipated within
the watershed and developmental pressure is relatively low although evidence of new home construction
was identified on two lots in the watershed.
2.2.4 Physiography, Geology, and Soils
The Site lies within the Southern Crystalline Ridges and Mountains sub - region of the Blue Ridge
ecoregion. This sub - region occurs primarily on Precambrian igneous and high -grade metamorphic rocks,
which are mostly gneiss and schist, covered by well- drained, acidic, loamy soils. The local lithology is
mapped as biotite gneiss.
The valleys associated with Bumgarner Branch and its tributaries within the project extents are Type II
colluvial valleys (Rosgen). The valleys present a wash -slope morphology with cross - slopes ranging from
3% to 22% and a longitudinal slope approximately 3 %.
Soils found on site include the Cullowhee fine sandy loam and Whiteside - Tuckasegee complex, which
consists of a fine sandy loam in the upper horizon and a cobbly sandy clay loam in the lower horizon.
None of the soils found on the site are considered hydric (See Table 4.2).
2.2.5 Historical Land Use and Development Trends
The Junes Branch Site encompasses approximately 5.7 acres of pastureland for horses, hay production,
and some forest stands. Grazing livestock have historically had access to most stream reaches and
adjacent terraces. The lack of deep- rooted vegetation and unstable channel characteristics appear to have
contributed to the degradation of stream banks.
Historic land use at the Site has consisted primarily of agriculture and livestock grazing. Additional land
use practices, including the maintenance and removal of riparian vegetation and the relocating, dredging,
and straightening of on -site streams have contributed to unstable channel characteristics and degraded
water quality. Historic wetlands were likely drained in order to maximize agricultural production.
2.2.6 Existing Site Conditions
In order to assess existing geomorphic conditions, cross section measurements were taken at seventeen
(17) locations within the site. These measurements were used to evaluate existing width -depth ratios,
bank - height ratios, entrenchment ratios and stream classification (See Appendix Q. Additionally, a bed
width index and a maximum depth index were calculated to assess departure from reference conditions.
Data collected from naturalized streams in the surrounding watersheds, the reference reach surveys and
the regional curve sites were used to develop regional hydraulic geometry relationships for reference
channel bed width and reference maximum bankfull.
The bed width index (BWI) was calculated by dividing the channel bed width measurements taken from
the site by the reference bed width and the max depth index (MDI) was calculated by dividing the
measured maximum bankfull depth by the reference maximum bankfull depth. BWI values less than 1.0
indicate that the bed is narrower than the natural bed width and there will be a tendency for the channel to
widen resulting in scour at the toe of bank. MDI values greater than 1.0 indicate that the channel depth is
greater than the natural channel depth and that the resulting increase in shear stress may cause scour in the
bed.
June's Branch NCEEP Mitigation Plan June 2012

Vertical and lateral stability were further evaluated by mapping existing erosional and depositional
features throughout the site and calculating bank erosion hazard index (BEHI) and near -bank stress (NBS)
rating (Appendix C4).
Bumgarner Branch
The majority of Bumgarner Branch classifies as a Type G stream with low width -depth ratios typically
ranging from 5 to 9 and entrenchment ratios typically ranging from 1.5 to 2.2. The bank- height ratios on
Bumgarner are typically within the range of 1.5 to 4.6. Additionally, the BWI values range for 0.5 to 0.7
while the MDI values range from 0.3 to 1.3 and the bankfull width of the existing channel is
approximately 65% of the reference width. This suggests that future adjustments of the channel will occur
in the form of widening of the bed width resulting in additional bank erosion.
Visual inspection of the soil horizons exposed along the banks of Bumgarner Branch reveal no evidence
of a gravel layer or stream bed layer occurring above the present stream bed elevation. Three (3) test pits
were excavated with a track -hoe on lower Bumgarner. One test pit exposed thin gravel layers (0. Ift - 0.2
ft thick) at depths of 2 ft and 4 ft below existing grade. The other two pits revealed no gravel layers above
the existing stream bed. However, both contained a buried `A' horizon at a depth of 2 ft and a substantial
gravel layer at a depth of 3 ft. It is possible that rapid aggradation of the valley and subsequent incision of
the channel have returned the stream to a former vertical position. It should be noted that where riffles
appear stable the bed is difficult to probe and larger bed material is present. Since the bed material does
not generally present as a cobble bed it is possible that the channel incision has exposed a historic cobble
bed, supporting the theory of rapid aggradation and subsequent incision of the channel.
The pipe culvert under Fairview Road on Bumgarner Branch is perched above the channel invert on the
downstream side, indicating that the channel bed has incised since the installation of the pipe. On the
upstream side the pipe has acted as a grade control and prevented the channel from down cutting. The
presence of the pipe may be contributing to deposition of the suspended material on the floodplain.
The reach of Bumgarner Branch upstream of Fairview Road is distinctive from the rest of Bumgarner
Branch in that it classifies as a Type E stream due to the higher entrenchment ratios of 5 to 6. Through
this reach bank - height ratios range from 1.1 to 1.5 and the MDI values range from 0.9 to 1.3 suggesting
that there may be some level of departure from reference conditions but that vertical stress on the bed is
probably not excessive. However, the BWI values through this reach range from 0.3 to 0.6 indicating a
high potential for the channel bed to widen to two or three times its present width. It is likely that the
continued impacts by livestock are perpetuating a state whereby a thalweg -sized channel is formed inside
of a larger channel that is partially stabilized with herbaceous cover.
Junes Branch
The majority of Junes Branch classifies as a Type G stream with low width -depth ratios typically ranging
from 5 to 9 and entrenchment ratios typically ranging from 1.8 to 2.2. The bank - height ratio on Junes
Branch ranges from 1.9 to 3.3. Additionally, the BWI values range from 0.4 to 0.7 while the MDI values
typically range from 1.2 to 1.7. These values suggest that there is considerable stress on the bed of the
channel that will likely result in future widening and down cutting.
The Junes Branch channel has the appearance of a narrow thalweg cut into a former ditch bed. There is
evidence, particularly along the reach upstream of the driveway crossing, that the channel has been
dredged and relocated. This evidence consists of re- graded topography and a lower central valley position
that is offset from the present channel location. There were no instances of a exposed gravel layer or sand
layer in the banks that would indicate the stream previously occupied a higher elevation.
Five test pits were excavated on Junes Branch. Two of the pits contained a buried `A' horizon underlain
by a gravel layer 6 inches thick. One test pit revealed no gravel layer and the remaining two contained a 1
June's Branch NCEEP Mitigation Plan June 2012 4

ft thick gravel layer 2 to 3 ft below the terrace. It is unclear whether the gravel layer represents an early or
late Holocene deposit.
The bed of Junes Branch is composed primarily of sand that probes easily to a depth of 0.3 ft to 1.0 ft. In
many instances a dense gravel layer is encountered below the sand bed. There are a few short reaches
where the bed is composed of a significant fraction of large gravel and cobble. It appears that depositional
reaches are locally positioned downstream of headcutting reaches which are identified with the exposed
gravel and cobble bed sections. The present sediment loads are being routed by the incised channel
without significant accumulation of depositional material and the overall profile trend is degradational.
Higdon Branch
Higdon Branch is a small stream that has formed in the bottom of a larger dredged channel. The larger
dredged channel has a base width of approximately 12 feet with a spoil pile on the left bank that is 2 to 4
feet high and approximately 10 feet wide. The bed of the dredged channel and the bed of Higdon Branch
consists primarily of unconsolidated silt and sand indicating that the channel was probably originally
dredged deeper and has subsequently aggraded. Although erosion and stability are not major concerns on
this stream, the dredging has resulted in a stream that is completely isolated from the historic floodplain
and valley.
Doris Branch
Doris Branch is a headwater seep that forms into an intermittent channel. The existing intermittent
channel was apparently frequently excavated to drain the adjacent floodplain and wetlands. A distinctive
spoil berm approximately 2 feet above the natural ground extends along the entire length of this channel
on the right bank. This spoil berm separates the wetlands and Doris Branch from the Bumgarner Branch
floodplain.

6.0 CREDIT RELEASE SCHEDULE
All credit releases will be based on the total credit generated as reported by the as -built survey of the
mitigation site. Under no circumstances shall any mitigation project be debited until the necessary DA
authorization has been received for its construction or the District Engineer (DE) has otherwise provided
written approval for the project in the case where no DA authorization is required for construction of the
mitigation project. The DE, in consultation with the Interagency Review Team (IRT), will determine if
performance standards have been satisfied sufficiently to meet the requirements of the release schedules
below. In cases where some performance standards have not been met, credits may still be released
depending on the specifics of the case. Monitoring may be required to restart or be extended, depending
on the extent to which the site fails to meet the specified performance standard. The release of project
credits will be subject to the criteria described as follows:

Initial Allocation of Released Credits
The initial allocation of released credits, as specified in the mitigation plan can be released by the NCEEP
without prior written approval of the DE upon satisfactory completion of the following activities:
a. Approval of the final Mitigation Plan
b. Recordation of the preservation mechanism, as well as a title opinion acceptable to the USACE
covering the property
c. Completion of project construction (the initial physical and biological improvements to the
mitigation site) pursuant to the mitigation plan; Per the NCEEP Instrument, construction means
that a mitigation site has been constructed in its entirety, to include planting, and an as -built
report has been produced. As -built reports must be sealed by an engineer prior to project
closeout, if appropriate but not prior to the initial allocation of released credits.
d. Receipt of necessary DA permit authorization or written DA approval for projects where DA
permit issuance is not required.
Subsequent Credit Releases
All subsequent credit releases must be approved by the DE, in consultation with the IRT, based on a
determination that required performance standards have been achieved. For stream projects a reserve of
15% of a site's total stream credits shall be released after two bank -full events have occurred, in separate
years, provided the channel is stable and all other performance standards are met. In the event that less
than two bank -full events occur during the monitoring period, release of these reserve credits shall be at
the discretion of the IRT. As projects approach milestones associated with credit release, the NCEEP will
submit a request for credit release to the DE along with documentation substantiating achievement of
criteria required for release to occur. This documentation will be included with the annual monitoring
report.

7.0 MITIGATION WORK PLAN
7.1 Description of Target Stream and Vegetation Communities
Reference reaches were sought to provide a target for design of the proposed streams. Searches were
conducted first upstream and downstream of the Site and then into surrounding watersheds to find
suitable references that contained comparable slope, bed material, and valley type. A Type B4 reference
was located on Cold Springs Creek, a tributary to the Pigeon River in Haywood County. The reference
vegetation community data was also collected at the Cold Springs reference site.
7. 1.1 Reference Reach
The reference reach was selected to represent the probable configurations for the proposed stream
restoration. Detailed geomorphic survey and Level II Rosgen classifications were conducted on three
reaches of Cold Springs for a total of 1000 LF or 44 times bankfull width (See Appendix Q.
Cold Springs Reference
The Cold Springs Creek reference reach is located in the Blue Ridge hydrophysiographic region of North
Carolina. The Cold Springs watershed has many characteristics in common with the Junes Branch
watershed including average annual rainfall, elevation changes and valley type. The reference watershed
is located in the Harmon Den Wildlife Management area of the Great Smokey Mountains National Park
and is predominantly forested. The drainage area for the Cold Springs Creek reference is 2.63 miZ.
The Cold Springs reach is representative of a B4 channel in a moderately sloped valley with a narrow,
constrained floodplain. Bed material, channel slope and valley form of this stream are consistent with the
Site and provide reasonable analogues for the potential channel forms that can be expected at the Site.
The Cold Springs reference reaches have a range of D50 of 20 mm to 46 mm, D84 of 84 mm to 168 mm,
channel slope of 2.3% to 3.2 %, width /depth ratio of 16 to 21 and sinuosity of 1.05 to 1.10.
Discharge and Bank-full Verification
Bankfull was readily identified on Cold Springs as it exhibited consistent indicators throughout the reach.
Verification of bankfull was accomplished by plotting the bankfull cross sectional area against the
regional curve data (Appendix Q. The graph indicates that the bankfull identified in the surveyed reach
is slightly lower than the line of the regional curve but consistent with the range of data collected in the
regional curve study.
After verification of bankfull cross sectional area, bankfull discharge was calculated for the surveyed
reach using a single- section analysis. Manning's `n' was estimated from relative roughness calculations
of the bed material and from observation of the channel form and vegetation conditions. Water surface
slope was assumed to be consistent with the slope of the bed profile. Discharge was then compared to the
regional curve data which indicated that the calculated bankfull discharges were consistent with the
regional curve data.
Channel Stability Assessment
A detailed channel stability assessment was not performed for these reaches since the bank and bed
stability was apparent from observation. Subsequent review of the surveyed dimensions confirmed that
width -depth ratios and bank - height ratios were within the appropriate range for stable, self - maintaining
streams. Additional observations included significant upstream and downstream reconnaissance to
identify any past, present, or future signs or sources of degradation.
June's Branch NCEEP Mitigation Plan June 2012 23

Limited Reach References
Through the course of conducting the reference reach searches, several streams were identified as
possessing qualities of stability and natural form. However, these reaches were determined not to be
suitable references for the project due to incompatible stream type, valley form, or insufficient reach
length. In these locations morphological measurements were taken to supplement the data acquired from
the reference reach sites. Measurements on nine individual reaches included bankfull width, bed width,
depth of bankfull, toe depth, and width of thalweg.
7.1.2 Reference Vegetation Community
A plant community survey was performed at Cold Spring Creek on November 9, 2007. This small stream
plant community, common to the Appalachian Mountains, is located within a mesic hardwood forest
cove. The riparian plant community most closely resembles a Montane Alluvial Forest as described by
Schafale and Weakley (1990). Canopy species observed included American beech (Fagus grandifolia),
black birch (Betula lenta), Eastern hemlock (Tsuga canadensis), red oak (Quercus rubra), sugar maple
(Acer saccharum), and tulip poplar (Liriodendron tulipifera). Subcanopy species included American
holly (Ilex opaca), iron wood (Carpinus caroliniana), and rosebay rhododendron (Rhododendron
maximum). Herbaceous species included American alumroot (Heuchera americana), Aster sp., Christmas
fern (Polystichum acrostichoides), dog hobble (Leucothoe fontanesiana), golden ragwort (Senecio
aureus), lady fern (Athyrium asplentoides), sphagnum moss (Sphagnum spp.), woodland stonecrop
(Sedum ternatum), and Viola spp.
7.2 Design Narrative
7.2.1 Restoration Approach
Bumgarner Branch
Bumgamer Branch is divided into two main reaches; Reach 1 is located upstream of the confluence with
Junes Branch and Reach 2 is located downstream of the confluence with Junes Branch. Reach 1 is further
subdivided into Reach la, which is located upstream of Fairview Road and Reach lb, which is
downstream of Fairview Road.
Reach la is proposed for Priority I restoration as a Type B4 stream with moderate sinuosity and an
average channel slope of 2.4 %. Consideration was given to improving Reach la using a minimally
invasive approach such as enhancement and stabilization or simply excluding livestock and allowing
natural recovery of the stream. These considerations stem from the observations that this section of stream
is not excessively incised and maintains a functional connection with its floodplain. Additionally the
presence of herbaceous cover provides some degree of stability for the soils outside of the channel banks.
The overriding concern with an enhancement or "livestock exclusion only" approach is the nature of the
anticipated channel adjustments. Since the existing channel bed width is only 3 feet, it is expected that
stable channel forms will not develop until the channel bed has widened to at least 8 feet. Channel
widening will accelerate as successional woody vegetation replaces the existing herbaceous vegetation.
This is demonstrated immediately upstream of the Site where the channel has widened to approximately 6
feet in response to the absence of livestock impacts and shading from alders and privet. Even with a bed
width of 6 feet, the channel had not reached a stable cross section and exhibits evidence of bank scour. If
this progression in channel form is permitted to occur through Reach la, it is estimated that
approximately 2,500 ft' of soil (150 tons) will be eroded from the banks and transported to the
downstream reaches. Additionally, a temporal loss in ecological recovery will be associated with this
scenario since it can be expected that this process with likely take years if not decades.
June's Branch NCEEP Mitigation Plan June 2012 24

The recommended approach is for complete reconstruction of a Type B4 stream. This will provide for
construction of the proper cross sectional geometry that will reduce stress on the banks and eliminate
bank scour. Additionally, reconstruction will provide the opportunity to harvest the cobble bed material
that is buried under the finer sediments and utilize it to construct proper, functional riffles. Riffles
constructed from native gravel and cobble material along with step -pool structures will provide
immediate habitat features and a dramatic functional lift.
The case for restoration on Reach lb is more obvious since the channel is more incised and the extent of
bank erosion is more apparent. Additionally, the incision of the channel bed has resulted in a "hanging
invert" at the downstream end of the pipe culvert under Fairview Road. Restoration efforts will raise the
channel bed to reconnect the channel to the floodplain and restore connectivity for passage of aquatic life
through the culvert.
Reach 2 is proposed for Priority I restoration as a Type 134c stream with an average channel slope of
1.5 %. Priority I and Priority II approaches were both considered on this reach. The primary factor for
considering the use of a Priority II approach was the presence of suitable bed material and bed form in
several locations. Appropriate bank features and vegetation were generally absent along this reach and
therefore did not provide an additional incentive for this approach. Disincentives for pursuing a Priority II
approach included extensive excavation required to construct the proper channel and floodplain bench
dimensions, concerns associated with establishing vegetation on excavated soil horizons, and loss of
connectivity with the historic floodplain. Although generation of wetland credits is not a stated goal of
this project, a Priority I approach does provide the opportunity to enhance existing wetland and floodplain
groundwater hydrology.
Junes Branch
Junes Branch is proposed for restoration as a Type B4 stream with moderate sinuosity and an average
channel slope of 2.5 %. Full reconstruction is required to address the degraded conditions of severe
channel incision, unstable banks and improper channel dimensions which are negatively affecting stream
functions. A Priority I approach is the goal for the entire reach of Junes Branch, however, a Priority II
approach is required in a few locations due to topographic constraints.
Higdon Branch
Higdon Branch is proposed for restoration as a Type B4 and 134c stream. The case for restoration on
Higdon Branch is not made on the basis of channel stability, although there are several instances of
channel bed nick points and bank erosion. Most of these occurrences are relatively minor and could be
stabilized with local treatments. The overriding issue affecting ecological function on this reach is
extreme topographic separation of Higdon Branch from the adjacent floodplains caused by the
agricultural ditching of the stream. This separation is further exaggerated by the adjacent spoil berm. In
order to reconnect Higdon to the adjacent natural terrain, improve floodplain groundwater hydrology and
assist in wetland recovery, a Priority I approach is recommended for Higdon Branch. A Priority II
approach will be required of the upstream end of this reach in order to tie the profile into the existing pipe
at Fairview Road.
Doris Branch
Doris Branch is proposed for restoration as a Type B4 stream. The case for restoration of Doris Branch is
based solely on the potential to improve ecological conditions. Raising the bed of Doris Branch will
improve groundwater hydrology in the adjacent wetlands and removal of the adjacent spoil berm will
reconnect Doris Branch and the wetlands to the Bumgarner Branch floodplain.
7.2.2 Restoration Methods
Restoration of Type B4 and 134c streams will consist of constructing a low to moderate sinuosity (1.05-
1.10) stream with a moderate width -depth ratio (13 -17) that accesses the floodplain at greater-than-
June's Branch NCEEP Mitigation Plan June 2012 25

bankfull flows. For streams with average channel slopes from 1.5% to 4% the bed profile form is in a
range that is transitioning from riffle -pool morphology at the lower slopes to step -pool morphology at the
steeper slopes. The profile is therefore a combination of riffles, rapids, and step -pool features.
Exploration for buried bed material will be conducted in proximity of the channel work to harvest
available bed material for reuse in the constructed channel. Where the quantity of existing bed material is
insufficient it will be supplemented with off -site material of appropriate size.
In some locations topographic constraints prevent Priority I restoration and it will be necessary to
construct a bankfull bench. Along these reaches, topsoil will be removed prior to excavation and
stockpiled. After completion of grading operations, topsoil will be redistributed across the floodplain
bench to facilitate vegetation success.
Boulder and log structures will be used to provide vertical stability to the channel, assist in maintaining
riffle, run and pool features and to provide habitat features. Run structures will generally be placed at the
tail -of -riffle location to support the upstream riffle grade. Run structures will be composed of a series of
small steps and pools which will transition into the main downstream pool. Log sills will be used in a
similar fashion on smaller streams or on flatter grade reaches. Log J -hooks will be used to shift the flow
away from the outside banks on selected meander bends. Brush -toe structures will be installed on the
outside of certain meander bends to provide bank stability, increase bank roughness, and provide aquatic
habitat.
Trees with diameters in the range of 12" to 24" will be harvested from the site or nearby property for use
as in- stream structures. Small diameter (less than 6 ") woody plants suitable for transplanting will be
harvested on -site where available.
Earthwork activities will include excavation of the proposed channels, partial or complete backfilling of
existing channels and removal of existing spoil berms. Grading work is designed to restore or mimic
natural contours.
Cross pipes will be oversized so that the pipe diameter will be comparable to the channel bed width where
practical. The invert of the pipe will be buried below the bed of the channel to allow bed material to pass
through the pipe. A boulder grade control structure will be placed downstream of the pipe to hold the low
water surface just above the outlet and allow for aquatic life passage. Smaller diameter pipes will be
placed on either side of the primary pipe to provide additional floodplain flow conveyance.
All disturbed areas will be stabilized with temporary and permanent seed and covered with straw or
mulch. Live stakes will be installed on the stream banks in accordance with the planting plan in Appendix
D. The entire conservation easement area will be planted with bare root seedlings in accordance with the
planting plan in Appendix D.
7.2.3 Data Analysis
Hydraulic and Hydrologic Analysis
The proposed channel sections were evaluated for their ability to convey the bankfull flows and the flood
flows of the watershed by performing a hydraulic analysis. Flood flow hydrology was based on USGS
Regional Regression equations for the Blue Ridge- Piedmont hydrologic area. Bankfull discharge was
based on the NRCS revised regional curves for the North Carolina Mountain and Piedmont hydrologic
area. The analysis consisted of first modeling the existing conditions with the HEC -RAS water surface
profile model. Cross sections were taken through the channel and the adjacent valley at representative
locations throughout the project reach. Existing hydraulic conditions were evaluated and the model
calibrated based on available site data.
June's Branch NCEEP Mitigation Plan June 2012 26

The ability to accurately verify bankfull discharge within the site is limited by the degraded channel
conditions and the lack of clear bankfull indicators. On a coarse scale, the existing HEC -RAS model does
indicate bankfull water surface elevations within the channel banks where the channel is incised and
above inner berm features where present. Additional bankfull verification is provided through the
hydraulic geometry curves assembled from locations on site, immediately adjacent to the site, within the
watershed and the neighboring watersheds (See Appendix C1).
Proposed conditions were analyzed by revising the existing sections based on the proposed channel
geometry and by revising the model to reflect proposed pattern conditions and anticipated future
roughness coefficients. Comparison of the existing and proposed HEC -RAS models provided assistance
in the analysis of the sediment transport, bankfull flow capacity and confirmation that there will be no
hydraulic trespass onto adjacent properties.
Sediment Competence Analysis
Data collection for sediment competence analysis included riffle and reach pebble counts and bulk
samples on Junes Branch and Bumgarner Branch. The bed material consists of a mix of sand, gravel and
cobble with a large constituent being composed of sand (40 % -60 %). Using the raw data from the Site for
competence calculations provides essentially meaningless results since the high sand content skews the
size of the D50 to sand sized particles. Even using the raw data collected from the upstream off -site
reaches which both have a D50 of 18 mm provides dubious results. In this case the predicted stable
channel slopes would be 1.2% and 0.8% on Bumgarner and Junes respectively, while the valley slopes are
2.3% and 2.8 %. This would suggest that the stable channel slopes and the existing valley slopes are
incompatible.
There are several possible explanations for the incongruence of Site data and the Site topography. The
first attempt to reconcile the data was to recognize the large sand content as wash load and remove it from
the bed load calculations. The adjusted data provides a D50 in the range of 37 mm to 46 mm on
Bumgarner and 16 mm on Junes Branch. Using the adjusted D50 as the representative particle in the
competence calculations improves the results but does not completely resolve the incongruence with the
valley slopes.
In order to better understand the relationship between the bed material, the channel slope and the valley
slope a detailed assessment was conducted of the reference reach competence. Critical dimensionless
shear (i, *) was calculated using the Andrew's equation (1984), the slope based Lamb equation (2008),
and the range of standard values available in the scientific literature. Shear stress was used to predict
stable channel slopes for the rifle pebble count, reach pebble count and bulk sample D50, D84, D95 and
Dmax particle sizes. The combination that provided the best agreement with the existing channel slopes
was the standard critical shear value of 0.047 with the D84 representing the threshold particle size. This
result is consistent with field observations of the channel as a relatively low sediment supply stream that
is at least partially self - armored.
Although the present condition of Bumgarner and Junes Branch is not a low sediment supply system it is
reasonable to consider the gravel and cobble fraction of the bed material to be in low supply. Given that
condition, the stable configuration of these streams would be a partially armored bed of gravel and cobble
that permits the transport of the sand wash load through the system. Shear stress calculations were
performed using a critical dimensionless shear value of 0.04 and a threshold particle size of 73 mm on
Bumgarner and 56 mm on Junes Branch. The critical dimensionless shear value was selected to be
slightly less than the reference reach value to account for potentially higher mobility associated with the
disturbed nature of the post construction bed conditions. The threshold particle sizes were taken from the
average of the two largest particles in the bulk samples from upstream of the Site. These particle sizes
were consistent with the D84 sizes from the adjusted data sets and are representative of what may actually

be supplied by the watershed. The shear stress calculations were used to predict stable channel slopes of
approximately 2.0% which is more consistent with the overall valley slopes.
Sediment Capacity Analysis
In order to assist in evaluating the sediment capacity, a set of consecutive pit traps were installed in the
stream bed at the downstream end of Bumgarner Branch. Three samples were collected from the pit traps
following rainfall events. These samples were sieved and weighed. The last sample collected from the pit
trap was following a rainfall event that registered 0.85 ft. on the crest gauge. From this sample it was
estimated that the total bed load was between 0.3 to 0.6 tons for this less- than - bankfull event.
A flow duration hydrograph was constructed to simulate the third sampling event in order to model
sediment transport using the quasi- unsteady flow routine in HEC -RAS. Seven sediment transport
functions were evaluated for consistency with sediment data collected in the pit traps. The Wilcock
transport function provided results that fit best with the data. The Wilcock function predicted 0.8 to 2.7
tons of cumulative sediment output at the downstream end of Bumgarner while the other sediment
transport function predicted sediment output values more than two orders of magnitude greater than the
estimated load. Based on this correlation, the Wilcock function was used to evaluate sediment capacity
under existing and proposed conditions.
Two quasi- unsteady simulations were run in HEC -RAS to qualitatively to evaluate the sediment transport
capacity. The modeling consisted of running the bankfull discharge and the 10 -year discharge for a
constant 24 hour simulation on a one hour computational increment cycle. Existing and proposed models
were compared for differences in channel bed elevation and cumulative sediment output.
With respect to changes in the channel invert elevation, Bumgarner and Junes Branch perform similarly
under existing and proposed conditions. Bed invert changes are generally between 0.1 ft. and 0.2 ft. for
the bankfull flow and between 0.2 ft. and 0.3 ft. for the 10 -year flow. One exception is that the existing
model predicts approximately 1 ft. of aggradation at the downstream end of Junes Branch in the bankfull
flow and 1 ft. of scour in the 10 -year flow while the proposed model predicts less than 0.2 ft. of bed
change.
With respect to cumulative mass output the model predicts an approximate average reduction of 40% in
the sediment output. This is primarily in response to the proposed reconfiguration of the bed material
composition which will reduce the percentage of sand from 50% to 20% of the total. Given the limited
predicted change in proposed channel invert elevation this can be interpreted as not resulting in
aggradation.
The design configuration was also evaluated for sediment transport capacity by assessing continuity and
magnitude of stream power. Generally the proposed conditions model show a significant decrease in
stream power in the higher frequency events with comparable or somewhat higher stream power in the
lower frequency events. The decrease in stream power in the higher frequency events is to be expected
due to the proposed increase in channel width /depth ratio. However, this is not troubling since the actual
stream power values are sufficiently high to transport the sand particles which constitute the main wash
load component.

8.0 MAINTENANCE PLAN
EBX will monitor the site on a regular basis and shall conduct a physical inspection of the site a minimum
of once per year throughout the post - construction monitoring period until performance standards are met.
These site inspections may identify site components and features that require routine maintenance.
Routine maintenance should be expected most often in the first two years following site construction and
may include the following:
Component /Feature
Maintenance through project close -out
Stream
Routine channel maintenance and repair activities may include
chinking of in- stream structures to prevent piping, securing of loose
coir matting, and supplemental installations of live stakes and other
target vegetation along the channel. Areas where storm water and
floodplain flows intercept the channel may also require
maintenance to prevent bank failures and head-cutting.
Wetland
Routine wetland maintenance and repair activities may include
securing of loose coir matting and supplemental installations of live
stakes and other target vegetation within the wetland. Areas where
storm water and floodplain flows intercept the wetland may also
require maintenance to prevent scour.
Vegetation
Vegetation shall be maintained to ensure the health and vigor of the
targeted plant community. Routine vegetation maintenance and
repair activities may include supplemental planting, pruning,
mulching, and fertilizing. Exotic invasive plant species shall be
controlled by mechanical and /or chemical methods. Any vegetation
control requiring herbicide application will be performed in
accordance with NC Department of Agriculture (NCDA) rules and
regulations.
Site Boundary
Site boundaries shall be identified in the field to ensure clear
distinction between the mitigation site and adjacent properties.
Boundaries may be identified by fence, marker, bollard, post, tree -
blazing, or other means as allowed by site conditions and /or
conservation easement. Boundary markers disturbed, damaged, or
destroyed will be repaired and /or replaced on an as needed basis.
Utility Right -of -Way
Utility rights -of -way within the site may be maintained only as
allowed by Conservation Easement or existing easement, deed
restrictions, rights of way, or corridor agreements.
Ford Crossing
Ford crossings within the site may be maintained only as allowed
by Conservation Easement or existing easement, deed restrictions,
rights of way, or corridor agreements.
Road Crossing
Road crossings within the site may be maintained only as allowed
by Conservation Easement or existing easement, deed restrictions,
rights of way, or corridor agreements.
Storm water Management Device
Storm water management devices will be monitored and maintained
per the protocols and procedures defined by the NC Division of
Water Quality Storm Water Best Management Practices Manual.
June's Branch NCEEP Mitigation Plan June 2012 30

9.0 PERFORMANCE STANDARDS
Morphologic Parameters and Channel Stability
Restored and enhanced streams should demonstrate morphologic stability to be considered successful.
Stability does not equate to an absence of change, but rather to sustainable rates of change or stable
patterns of variation. Restored streams often demonstrate some level of initial adjustment in the several
months that follow construction and some change /variation subsequent to that is also to be expected.
However, the observed change should not be unidirectional such that it represents a robust trend. If some
trend is evident, it should be very modest or indicate migration to a stable form.
Dimension
Cross - section measurements should indicate little change from the as -built cross - sections. If changes do
occur, they will be evaluated to determine whether the adjustments are associated with increased stability
or whether they indicate movement towards an unstable condition. Monitoring should indicate that bank
height ratios have remained less than 1.3 and entrenchment ratios are greater than 1.4.
Pattern and Profile
Measurements and calculated values should indicate stability with little deviation from as -built conditions
and established morphological ranges for the restored stream type. Pool depths may vary from year to
year, but the majority should maintain depths sufficient to be observed as distinct features in the profile.
The pools should maintain their depth with flatter water surface slopes, while the riffles should remain
shallower and steeper. Pattern measurements will not be collected unless conditions seem to indicate that
a detectable change appears to have occurred based on profile and/or dimension measurements.
Substrate
Calculated D50 and D84 values should indicate coarser size class distribution of bed materials in riffles and
finer size class distribution in pools. The majority of riffle pebble counts should indicate maintenance or
coarsening of substrate distributions. Generally, it is anticipated that the bed material will coarsen over
time.
Sediment Transport
Depositional features should be consistent with a stable stream that is effectively managing its sediment
load. Point bar and inner berm features, if present, should develop without excessive encroachment of the
channel. Isolated development of robust (i.e. comprised of coarse material and /or vegetated actively
diverting flow) mid - channel or lateral bars will be acceptable. Likewise, development of a higher number
of mid - channel or lateral bars that are minor in terms of their permanency such that profile measurements
do not indicate systemic aggradation will be acceptable, but trends in the development of robust mid -
channel or alternating bar features will be considered a destabilizing condition and may require
intervention or have success implications.
Surface Water Hydrology
Monitoring of stream surface water stages should indicate recurrence of bankfull flow on average every 1
to 2 years. At a minimum, throughout the monitoring period, the surface water stage should achieve
bankfull or greater elevations at least twice.
Vegetation
Riparian vegetation monitoring shall be conducted for a minimum of seven years to ensure that success
criteria are met per USACE guidelines. Accordingly, success criteria will consist of a minimum survival
of 320 stems per acre by the end of the Year 3 monitoring period and a minimum of 260 stems per acre at
the end of Year 5. If monitoring indicates either that the specified survival rate is not being met or the
development of detrimental conditions (i.e., invasive species, diseased vegetation), appropriate corrective
actions will be developed and implemented.
