local stormwater requirement, etc.): not applicable
Size of watershed draining to pond: n/a Expected pond surface area: n/a
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Stream stabilization will onlv be conducted in areas exhibitinz active erosion. Due to the vallev
constraints, landowner stipulations, and existing channel morphology at the project site, stream
channel relocation is not feasible. Construction access roads are proposed in predetermined
areas to minimize the impact effects o heavy equipment on the channel and existing riparian
zones. Construction will be conducted durinz low flow events. Any rises or increases in flows
will require that equipment exit the channel. Streambanks disturbed via stabilization activities
will be seeded and covered immediately.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
Page 9 of 12
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.Lis/ncwetlands/strmg.i.de.h.tmi.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Not annlicable

1.0 INTRODUCTION
This stabilization plan addresses channel improvements to be implemented by the Natural
Resources Conservation Service (MRCS) along Raccoon Creek. The project includes a 2,700
linear-foot section of stream along the John Queen Farm, immediately east of Waynesville in
Haywood County (Figure 1). Mulkey Engineers and Consultants (MULKEY) was retained
by the NRCS to design and oversee the implementation of stabilization techniques using
natural channel design methodologies. Implementation is planned for the winter of
2003/2004.

Raccoon Creek is situated within the
French Broad River Basin in western
North Carolina. It is part of Subbasin 04-
03-05, including the Pigeon River, East
and West Fork Pigeon Rivers, Richland,
Jonathans, Crabtree, and Cataloochee
Creeks. Raccoon Creek originates
approximately two miles southeast of
Waynesville near Wolfpen Mountain. It
flows in a northerly direction along the
eastern edge of Waynesville through the
John Queen Farm and ultimately into
Richland Creek at bake Junaluska.
According to the North Carolina Division of Water Quality (NCDWQ, 2002), water quality
in this subbasin has shown improvement over the past several years. The headwaters of
Raccoon Creek continue to experience problems with non-point source pollution, mostly
from agriculture. Based on map reviews, the stream has also been channelized in several
areas. Very little riparian buffer is present throughout the lower portion of the creek. The
overall Raccoon Creek channel has no riparian buffer and exhibits signs of channelization
through a major portion of the John Queen project site.
2.0 OBJECTIVE
The objective of this project is to
reduce erosion and sedimentation
originating through this reach and
improve the overall habitat values,
both aquatic and terrestrial. This
objective will be met by establishing
rock structures (referred to as
vanes) within noted problem areas
to divert the shear stresses away
from the eroding streambanks.
This project is classified as
stabilization rather than restoration
due to several reasons: landowner
constraints; overall project costs; and existing land uses. Natural channel design
methodologies are preferred over traditional engineering approaches for this type of
stabilization. These methodologies will be implemented throughout the stabilization process
to ensure the channel dimension, pattern, and profile remain consistent and the reach does
not aggrade or degrade.
3.0 EXISTING CONDITIONS
Overall, this 2,700 linear-foot reach of Raccoon Creek appears moderately unstable. The
stream lacks overall sinuosity, which
denotes prior channelization. A
small levee existing along the left
streambank (facing downstream) at
the beginning of the project also
reveals evidence of previous
dredging. Vertical, eroding banks
exist along major portions of the
stream, especially around the
outsides of the confined meander
bends. Active scouring was evident
throughout most of these areas.
Bankfull indicators were difficult to
recognize in most cases, further
denoting the overall instability of
the channel. No riparian buffer
exists along the project.
3.1 Current Stream Classification
Raccoon Creek, from it source to Richland Creek, is designated as Class B waters. Class B
waters are suitable for primary recreation and other uses consistent with Class C standards.
Primary recreational activities include swimming, skin diving, water skiing, and similar uses
involving body contact with water where such activities take place in an organized manner or
on a frequent basis. There are no restrictions on watershed development or types of
discharges. The designation was given in April 1958 (NCDWQ, 2003). Existing site
conditions demonstrate that the watershed, including this reach of Raccoon Creek, has
undergone significant changes through the past decades. These changes include the
introduction of livestock and the removal of riparian vegetation. Therefore, this
classification is not an accurate reflection of the current conditions of the stream. Class C
waters are protected for secondary recreation, fishing, wildlife, fish and aquatic life
propagation and survival. These uses include wading, boating, and other aspects involving
human contact in an infrequent, unorganized, or incidental manner. Richland Creek,
downstream of Raccoon Creek, is designated as Class B waters upstream of Lake Junaluska
and Class C waters from the dam to the Pigeon River. These classifications were issued in
1958 and 1974, respectively.
3.2 Available Discharge Data
Discharge data for the West Fork Pigeon River was obtained from the United States
Geological Survey (USGS) Stream Gage approximately eight miles south of the project. No
Stream Gage data was available for Raccoon Creek. Daily discharges from October 2001 to
September 2003 are shown in the chart below. These discharges represent an increase in
rainfall and surface runoff for the period beginning October 2002 through the present time.
Evidence of additional bank destabilization along Raccoon Creek has confirmed this
analysis.

3.3 Existing Condition of Raccoon Creek
Longitudinal profile and cross section surveys were conducted along the reach during July
and August 2003. These surveys were confined to the main channel since work outside of
the existing streambanks was not part of the project. Longitudinal surveys were taken at the
head of each feature (riffle, run, pool, and glide) and at the maximum pool depths. A total
of five detailed cross sections were taken at predetermined locations along the reach (Figure
2). These cross sections were taken near areas where bank stabilization measures were
anticipated. Reference reach data is provided for comparison purposes only. This reference
reach survey was completed by the NRCS and covers a section of Raccoon Creek upstream
of the project area.
Based on the surveys, Raccoon Creek is characteristic of a manipulated "E4" stream type.
According to the morphological description presented in Applied Fluvial Geomorphology
(Rosgen, 1996), E4 stream types are channel systems with low to moderate sinuosity, gentle
to moderately steep channel gradients, very low width/depth ratios, gravel-dominated
channels with well developed floodplains. The E4 stream types are hydraulically efficient
channel forms which maintain a high sediment transport capacity. The narrow and relatively
deep channels maintain a high resistance to plan form adjustment which results in channel
stability without significant down-cutting. These channels are very stable unless the
streambanks have been disturbed, such as the John Queen Site. As a result, changes in
sediment supply and streamflow have occurred. This channel type is susceptible to
accelerated bank erosion due to the absence of riparian vegetation. Specific information
pertaining to the channel is presented in the abbreviated morphological table at the end of
this section. Surveys of the longitudinal profile and cross sections are shown in Appendix A.
A pavement/sub-pavement sample was taken near Station 22+00 to compare with pebble
counts conducted at each cross section. Based on the information collected, MULKEY was
able to calculate shear stress, velocities, and entrainment (point of incipient motion). The
results of the pebble counts and pavement/sub-pavement sample are presented in the chart
at the end of this section.
Cross Section No. 2 was used in the calculations for shear stress, entrainment, and velocity.
This section was chosen based on its relation to the overall assessment of the reach. The
entrainment of Raccoon Creek through this segment substantiated that the reach is unstable.
The required shear stress appears adequate to move the large particles; however, the duration
required to keep the particles moving downstream are not present due to the flashy flows of
the water course. Bankfull velocities were calculated using five different methodologies at
the cross section. Velocities averaged 6.73 feet per second (fps). Bankfull discharge was
estimated at 196.5 cubic feet per second (cfs). Detailed information regarding each of the
calculations is presented in Appendix B.

3.4 Stability Assessments
Two methods were used to analyze channel stability along this reach of Raccoon Creek:
Pfankuch and Bank Erosion Hazard Index (BEHI).
Pfankuch (1975) developed a system to rate channel stability which has been widely used by
stream restoration professionals. This system is used to quantitatively describe the potential
for sediment material detachment and changes in sediment supply due to changes in
streamflow and/or changes in watershed condition. It has also been used to generally assess
fisheries habitat conditions, and to indirectly assess streambank damage resulting from cattle
grazing. Since this method was developed prior to the stream classification system, the
good, fair, and poor rating values have been adjusted by stream type (Rosgen, 1996). The
overall rating for this reach was 100, which falls within the "poor" category.
Streambank erosion rates were
calculated using the BEHI method
as described and taught by Dave
Rosgen, Wildland Hydrology, Inc.
Bank erosion occurs as a result of a
number of processes, including dry
ravel, mass wasting, surface erosion,
hquification, freeze-thaw, fluvial
entrainment, and ice scour. The
ability of streambanks to resist
erosion is primarily determined by
the following factors:
? the ratio of streambank height
to bankfull stage;

? the ratio of riparian vegetation rooting depth to streambank height;
? the degree of rooting density;
? the composition of streambank materials;
? streambank angle (i.e., slope);
? bank material stratigraphy and presence of soil lenses; and
? bank surface protection afforded by debris and vegetation.
The vertical streambank at Station 7+00 was measured to determine an approximate erosion
rate per year. This vertical streambank provides an overall representation of the
streambanks through the project area. It was considered based on its anticipated sediment
contribution during high-flow events. The BEHI rating was 47.7, indicative of extreme bank
erosion potential. Based on this number, erosion rates could reach approximately 7 feet' per
year. This measurement was taken along the outside of a meander bend throughout an
unstable area. Overall, Raccoon Creek should exhibit a BEHI rating of very high, with
erosion rates averaging approximately 1 foot' per year per linear foot, or approximately 125
tons of sediment per year.
3.5 Reference Reach Comparison
Since this project is considered stabilization rather than restoration, reference reach data is
not generally required for design and implementation. However, MULKEY was able to
obtain reference reach data from the NRCS covering a short segment of Raccoon Creek
upstream of the project area. This data was used as a comparison between bankfull cross-
sectional area, width, depth, and discharge of Raccoon Creek and the North Carolina Rural
Mountain Regional Curves (NCSU SRI, 2003). Based on field surveys and bankfull
verifications, the data associated with bankfull cross-sectional area and bankfull width were
significantly below the 95% confidence intervals of the calculations. MULKEY compared
the findings with those associated with the existing reference reach data and noted the same
discrepancies. Ratios were calculated noting the differences with the reference reach data
and the regional curves. Based on these ratios, which were 0.53 for bankfull cross-sectional
area and 0.54 for bankfull width, the field determined cross-sectional areas and bankfull
widths at the five cross sections distinctly compare with the existing reference reach data.
Therefore, the determined locations of bankfull are justified, although they do not agree with
the regional curve data.
4.0 DESIGN RECOMMENDATIONS
Based on the existing condition surveys and interpretation of the data, this reach of Raccoon
Creek is unstable. Aggradation processes are associated with the following channel
adjustments: increase in width/depth ratio; increase in sediment storage; increase in bank
erosion rates; decrease in pool quality and other fishery habitat features; increase in the loss
of riparian land and associated sediment availability from bank erosion and lateral migration;
and increase in over-bank flooding. Most of these processes were observed along the 2,700
linear-foot reach. Photos are presented in Appendix C.
MULKEY offers the following recommendations for stabilizing this reach of Raccoon
Creek:
1. Construct cross vanes in pre-determined locations along the 2,700 linear-foot reach
to help maintain and possibly decrease the width/depth ratio. These structures will
be placed only in riffle sections and will provide bank stability, grade control, and
habitat for aquatic organisms.
2. Construct rock vanes along the outside of meander bends requiring stabilization.
These vanes will help redirect flows away from the outside banks, provide limited
bank stabilization, and enhance habitat for aquatic organisms.
3. Reduce existing levee heights and re-shape the stream banks. This recommendation
is feasible only in a limited number of locations. The levee along the western side of
the channel is approximately 150 feet in length. The vertical banks along both sides
of the channel will be reshaped from the bankfull elevation upward. This material
will act as additional fill required in areas associated with the installation of the cross
vanes.
4. Access roads will be placed along the western bank of the stream to allow
construction equipment and personnel to enter the reach with minimal disturbance.
The locations of these roads will be determined at the onset of construction to
minimize overall impacts to existing riparian areas. These roads will be re-graded
and planted upon completion of the in-stream work.
5. Enhance riparian buffers in areas where little to no buffers currently exist. These
buffers will be planted with native tree species.
Erosion and sediment control issues exist along this project. Special precautions will be
taken during construction to minimize unnecessary sedimentation into the stream. Sediment
control fencing may be established along the affected edges of the pasture. This fencing will
direct any loose sediments resulting from sheet flow into a storage area away from the
stream. Any areas excavated or voided of vegetation will be seeded and matted upon exit
from the area. Since in-stream work is required for this stabilization, all equipment will be
inspected for fluid leakage on a daily basis. Work will not be conducted during rain events
or when water levels are above average. All equipment will be stored outside of the stream
and its associated riparian area when not in use. The construction supervisor will oversee all
activities relating to in-stream work.
5.0 DESIGN IMPLEMENTATION
Implementation will follow the design sequence listed on the plan sheets. The installation of
structures will proceed from upstream to downstream. As a result, shifts or changes in the
flows can be addressed with the placement of structures downstream. The actual locations
of the structures may be adjusted, depending on site conditions. Implementation will follow
the proposed sequence listed below.
1. Staging areas for equipment and materials and access roads will be identified and
located in the existing pastures.
2. Access Point #1 from Sunnyside Road (SR 1809) will be constructed for upstream
work between Stations 0+00 and 15+00. A temporary culvert will be installed in the
roadside ditch to allow access for equipment and the staging of materials.
Contractor will place geotextile material and gravel for the roadways leading to and
from the construction areas. The fences adjacent to the creek on the John Queen
Property will be removed.
3. Access Point #2 from Ratcliffe Cove Road (SR 1818) will be constructed
downstream work between Stations 15+00 and 28+53. Contractor will place
geotextile material and gravel for the roadway leading to and from the construction
areas. The remaining fences adjacent to the creek on the John Queen Property will
be removed.
4. Contractor will begin stockpiling materials.
5. Approximate structure locations will be field located.
6. Structure Nos. 1 through 10 will be constructed and the banks associated with the
Queen property will be graded to the bankfull elevation, where necessary. Impacts
to existing vegetation will be minimized to the extent practicable. Excess soil will be
taken to Station Nos. 6+93, 12+37, 13+75, 21+10, and the wet area in the pasture.
The contactor will utilize the existing cattle crossing at Station 15+00 as a permanent
stream crossing.
7. The radius at Station 6+93 will be increased and Structure Nos. 11 through 13 will
be installed. A bankfull bench will be constructed throughout the area associated
with the old channel. The bench will be graded at a slope determined by the on-site
construction engineer and connected with existing ground.
8. Structure Nos. 14 through 17 will be constructed and the banks associated with the
Queen Property will be graded to the bankfull elevation, where necessary. Impacts
to the existing vegetation will be minimized to the extent practicable. Excess soil will
be taken to Station Nos. 12+37, 13+75, 21+10, and the wet area in the pasture.
9. The fence along the right bank facing downstream at Station 10+50 will be repaired.
10. Structure Nos. 18 and 19 will be constructed and the banks associated with the
Queen Property will be graded to the bankfull elevation, where necessary. Impacts
to the existing vegetation will be minimized to the extent practicable. Excess soil will
be taken to Station Nos. 12+37,13+75, 21+10, and the wet area in the pasture.
11. The existing center bar at Station No. 12+37 will be moved to the right side of the
channel. Structure No. 20 will be constructed and the banks associated with the
Queen Property will be graded to the bankfull elevation, where necessary. Impacts
to the existing vegetation will be minimized to the extent practicable.
12. Structure Nos. 21 through 23 will be constructed and the banks associated with the
Queen Property will be graded to the bankfull elevation, where necessary. The
radius at Station No. 13+80 will be increased and a bankfull bench will be
constructed throughout the area associated with the old channel. Impacts to the
existing vegetation will be minimized to the extent practicable. Excess soil will be
taken to Station No. 21+10 and the wet area in the pasture.
13. NRCS and Haywood County Soil and Water Conservation District personnel will
review the structures and associated earthwork between Station Nos. 0+00 and
15+00.
14. Access Point #1 will be seeded, covered with erosion control material, and planted
with native vegetation. The temporary culvert will be removed upon exit from this
area. All geotextile material and gravel associated with roadway access to the
construction areas will be removed.
15. Structure Nos. 24 through 32 will be constructed and the adjacent stream banks will
be graded to the bankfull elevation, where necessary. Impacts to the existing
vegetation will be minimized to the extent practicable. Excess soil will be taken to
Station No. 21+10 and the wet area in the pasture and Station No. 28+53.
16. The old channel at Station No. 21+10 will be filled and Structure No. 33 will be
installed.
17. Farm drains and two swales will be constructed to provide additional drainage for
the wet area in the pasture near Station No. 22+00.
18. Structure Nos. 34 through 44 will be constructed and the adjacent stream banks will
be graded to the bankfull elevation, where necessary. Impacts to the existing
vegetation will be minimized to the extent practicable. Excess soil will be taken to
Station No. 28+53 and stockpiled in a suitable location for the landowner's use.
Existing debris, rip rap, and rubble will be removed from the existing channel and
either buried on site or taken to a proper disposal facility.
19. The radius at Station 28+50 will be increased and Structure Nos. 45 and 46 will be
installed. A bankfull bench will be constructed throughout the area associated with
the old channel. The bench will be graded at a slope determined by the on-site
construction engineer and connected with existing ground.
20. NRCS and Haywood County Soil and Water Conservation District personnel will
review the structures, drainage, and associated earthwork between Station Nos.
15+00 and 28+53.
