Dear Mr. Haupt:
This Office is in receipt of the plans for the stream restoration projects of approximately 17,200 feet of
streams in the Buffalo Creek watershed in the Yadkin River Basin originally submitted to this Office on June 6,
2002. DWQ Staff reviewed the plans and determined that stream restoration and/or enhancement would be
achieved. As such, the stream impacts associated with the project may proceed without written approval.from
the Division. Please be advised that seven copies of a complete, formal application and a $475.00 fee is
required for projects intended for compensatory mitigation credit (see General Certification No. 3353, issued
r •?' ' 8, 2002). Any request for mitigation credit shall be addressed under separate cover.

Review Comments
Clear Creek Stream Restoration
DWQ Project No. 02-0598
Henderson County
Dear Mr. Guidry:
Staff of the Division of Water Quality has reviewed the package submitted for the 401 Water
Quality Certification and have visited the site of the proposed Clear Creek Stream Restoration
project. The following comments and recommendations are provided:
1 We agree with the stream classification of Clear Creek at the proposed restoration site to be
a C4 type stream; however, after looking at the reference reach site it appears that the stream
type for Bent Creek is a C3b. Also, there was no sinuosity data provided for Bent Creek.
2. Please review the stream orders for Clear Creek and Bent Creek. Reference reach streams
should be within one order of the stream being restored. You should confirm the stream
orders of Clear Creek and Bent Creek are within one stream order. Also, the drainage area
for Bent Creek is significantly less (eight times) than that of Clear Creek. Because of the
watershed size this may result in design problems.
3. Since Basin Creek is not with the same HUC Unit as Clear Creek and is extremely smaller than
Clear Creek, we are recommending that it not be used for design purposes.
4. On page 1 of the report under Design Goals, "Establish a riparian buffer of woody plant
species, preferably native." All plant species should be native and all exotic species should
be removed from the site.

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.
The temporary impacts are unavoidable due the nature of stream restoration work. The
construction will be staged and performed in such a manner that the disturbance to the aquatic
system is minimal. Construction,of new stream channel will be performed in the `dry' to the
maximum extent possible. Construction work will be scheduled to have a minimal impact on
gquatic and fish habitat.
Page 9 of 13
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
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
httl2:Hh2o.enr.state.ne.us/ncwetlands/strmgide.html.
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.
See attached Restoration Plan for existing conditions, proposed channel design planting
plan, and monitoring12lan. The preliminary drawings (plan view) show the boundaries of a
permanent conservation easement that overlays the project.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants

Clear Creek Restoration Design Report
Introduction
The North Carolina Wetlands Restoration Program (NCWRP) is sponsoring the
restoration of Clear Creek in the French Broad River Basin. EcoLogic
Associates, P.C. is the lead design firm contracted by the NCWRP to restore
approximately 1300 linear feet of Clear Creek (Map 1). Problems in this stream
reach include areas of tall, vertical, failing banks, beaver damage to vegetation,
and planform and cross sectional geometry instabilities. This document
summarizes the project's purpose, existing site conditions, assessment
methodologies, and proposed restoration design. Supporting information is
included in the attached appendices.
Design Goals
The design goals of the Clear Creek restoration project are as follows:
1. Improve water quality by reducing the sediment load generated by eroding
banks;
2. Reestablish stable channel dimension, pattern, and profile to Clear Creek;
3. Restore a functioning floodplain;
4. Establish a riparian buffer of woody plant species, preferably native;
5. Enhance aquatic and terrestrial habitats in the stream corridor; and
6. Stabilize banks to safeguard a sanitary sewer line that runs parallel to
Clear Creek along the left (south) side of the channel.
Design Procedure
Design procedures followed those outlined in River Restoration and Natural
Channel Design Course Handbook (Rosgen, 1998.) Using this method, new
dimension, pattern, and profile are designed for stability. Then shear stress and
sediment transport capacity are calculated to ensure that the proposed design
will effectively transport sediment without causing accelerated erosion or
excessive deposition. The steps that lead to the design plan are as follows:
1. Conduct a watershed characterization for the project reach;
2. Survey a gage in the same hydrophysiographic region to verify field
indicators associated with bankfull discharge;
3. Survey a reference reach in the same hydrophysiographic region;
4. Perform Level 2 and 3 classification and assessment of the project reach;
and
5. Develop a design plan based on reference reach data, design goals, and
existing site constraints.

Land Use
The Clear Creek restoration site has historically been used for pasture and more
recently, hay production. Prior to January 1951, the date of the oldest aerial
photograph available at the Henderson County NRCS Office, Clear Creek was
straightened. Presumably, it was straightened for agricultural purposes and for
construction of a sanitary sewer line, as the county was predominantly rural at
that time. Successive aerial photographs show the construction of 1-26 in 1965
and the progression of Clear Creek's evolution each decade for the last 50 years.
A 1969 aerial photograph (NCDOT) shows Clear Creek flowing straight, wide and
shallow, typical of an F stream type. The 1994 photograph shows that Clear
Creek is trying to reestablish meanders. The flow area has narrowed and
vegetated mid-channel bars have formed. (See photos 1 through 5).
The Clear Creek watershed consists primarily of woodland and agriculture with
some highway businesses located along Route 64. Several orchards are located
in the Clear Creek watershed, which extends to Bat Cave, NC.
Physical Setting
The Clear Creek restoration site is located in a relatively low slope mountain
valley in Henderson County, NC. It is a fourth order tributary to Mud Creek in the
French Broad River Basin. The restoration reach runs through a former
overgrazed pasture between 1-26 and Clear Creek Road. The watershed of this
section of Clear Creek has a drainage area of approximately 44 square miles.
Clear Creek is listed as Class C waters, protected for secondary recreation,
fishing, wildlife, fish and aquatic life propagation and survival, and agriculture.
There are no restrictions on watershed development activities.
Soils around Clear Creek are primarily Codorus loam, transitioning to a
Hayesville loam on the sloping hills to the north of the stream channel. Codorus
loam is moderately well drained to somewhat poorly drained, moderately
permeable, nearly level soils formed in micaceous alluvium. Hayesville loam is
well drained, moderately permeable, gently sloping to moderately steep soils
formed in residuum from granite, gneiss, and schist. (Henderson County Soil
Survey, USDA SCS, 1980)
Existing Condition Survey
An existing condition survey of Clear Creek was conducted in December 2001.
The pre-restoration stream length is 1315 linear feet from the riffle immediately
downstream of the 1-26 bridge to the sanitary sewer crossing immediately
upstream of the Clear Creek Bridge. Based on the Rosgen stream classification
system, this stream is a laterally unstable C4 (Applied River Morphology, D.
Rosgen, 1996, p. 6-5) (See Appendix 2).

Station 0+00 of the survey started near the 1-26 Bridge at the upstream limit of
the restoration reach. Stationing increases in a downstream direction to the
sanitary sewer crossing immediately upstream of the bridge at Clear Creek
Road.
Channel Dimension
The cross-section dimensions, such as bankfull depth, width, and area,
are typical for this stream type and drainage area (See Existing Condition
Survey, Appendix 2). The bank height ratio (low bank height/max. bankfull
depth) ranges from 1.3 near 1-26 to 1.6 nearer Clear Creek Road. Ideally,
when the stream has full access to its floodplain, this ratio equals 1.
These ratios show that the channel has incised and carries more than
bankfull flow before accessing its floodplain. This increases shear stress,
particularly on the bare, upper banks, and accelerates bank erosion. The
banks, comprised largely of sand and fine gravel, have bank height ratios
ranging from moderately unstable to highly unstable.
Channel; Pattern
Sinuosity, at 1.1, is low for a C stream type. The restoration reach is still
quite straight. Several, vegetated mid-channel bars have formed, splitting
flows. New meanders and floodplain benches are forming within the
channel. However, meander wavelength, radius of curvature, and belt
width are outside the range of stable C4 stream types.
Channel Profile
The upper riffle in the restoration reach is much steeper than the
remainder of the restoration reach, and particle sizes found there are
much larger than particles found in the remainder of the channel. This
may be explained by the presence of 1-26. The rock could have been a
by-product of highway construction in the mid-1960's. Upstream of 1-26,
Clear Creek flows through agricultural fields.
Upstream of the study reach, the channel has a wider channel width, bank
heights range from 4-6 feet above water surface, pools are relatively small
but range from 3.5 to greater than 4 feet deep, and a thin layer of fines
covering the gravel bottom is common. In the study reach, riffles and
pools are poorly defined and occur at irregularly spaced intervals. The
predominant particle size in the bed is gravel. (Existing Condition Survey,
Appendix 2)

Riparian Corridor and Floodplain Assessment
This property is currently an open field; one small section on the northwest
end was cut for hay this last season. The majority of the floodplain is
treeless with occasional single specimens or clumps of small trees and
shrubs in an infrequently mowed old field. There are mature large trees
directly along the banks of the creek, along a line of an old straight
channel and on uplands adjacent to the floodplain. Many of the woody
species are pioneers of disturbed sites. The tulip trees, red maples and
pines are now middle aged and surround the margins of the restoration.
There are also significant amounts of weedy species typical of alluvial
corridor sites. The restoration site includes riparian corridor, bottomland
floodplain, and upland zones and related vegetation.
The floodplain along the restoration reach is comprised of alluvial soils
covered in grass, mowed seasonally for hay. Historically, according to
Bob Carter, Henderson County District Conservationist, the restoration
site was used as pasture and was heavily overgrazed. This probably
accounts for the lack of native, shrubby species and the presence of
multiflora rose, which cows do not eat. Typical species found on the
floodplain are Fescue (Fetusca spp.), mutiflora rose (Rosa multiflora),
pokeweed (Phytolacca americana), and greenbriar (Smilax spo.) Woody
vegetation is limited along the study length of Clear Creek. Where woody
species are present, one can find river birch (Betula nigra), red maple
(Acer rubrum), box elder (Acer negundo), tulip tree (Liriodendron
tulipifera), pines (Pinus spp.), and tag alder (Alnus serrulata).
Since the stream is incised, several sections of bare, vertical banks are
exposed. Materials eroded from these areas are transported downstream
to Mud Creek since the stream has limited access to its floodplain. No
riparian wetland systems were identified within this reach; however,
wetland remnants occur within the outer edges of the floodplain as
evidenced by persistent wetland vegetation including rushes (Juncos sp)
and sedges (Scirpus sp, Carex sp). Approximately 3/4 of the length of the
project reach lacks comprehensive, woody riparian plant cover.
Bankfull Verification
The North Carolina Rural Piedmont Regional Curve and a gage analysis of the
Davidson River near Brevard in neighboring Transylvania County were used to
verify the bankfull indicators identified in the field. The NC Rural Mountain
Regional Curve estimates a 1.1-year return interval at that gage. We estimated a
return interval closer to a 1.46-year return.
Based on NC rural regional curve regression equations, bankfull cross sectional
area is estimated to be 286 sf on the mountain curve and 281 sf on the piedmont
3/26/2002 4 EcoLogic Associates
336-855-8108
curve (range 150 sf - 550 sf). The bankfull discharge estimate is based on
cross-sectional geometry of a relatively stable riffle section in the upper portion of
the Clear Creek study reach. Bankfull cross sectional area is calculated to be
222.6 square feet (sf). Bankfull discharge is estimated to be 1390 cfs. By
continuity, bankfull velocity is calculated at 6.2 fps.
Reference Reach Analysis
Bent Creek, located in Bent Creek Experimental Forest, of the Pisgah National
Forest in Buncombe County, is used in design as a C4 reference reach. Bent
Creek is a gravel bed C stream type located in a valley that is sometimes
confined on one side. Basin Creek, a C4 stream type in Wilkes County is also
used as a reference reach. The drainage areas of Bent Creek and Basin Creek
are smaller than that of Clear Creek. A summary of the Bent Creek data and
Basin Creek data can be found on the Morphological Data sheet in Appendix 4.
Shear Stress, Velocity, and Sediment Transport
The flow associated with the critical shear stress for the proposed channel must
be able to move the largest particle on the point bar. Entrainment calculations
based on the riffle pebble count and a sieved bar sample are included in
Appendix 3. Based on the equation rc; = 0.0834(dVd5o)-0.872 (Andrews, 1984), the
critical dimensionless shear stress for Clear Creek is 0.042. This value
corresponds to a required mean bankfull depth of 4.5 feet to move the largest
particle in the bar sample. Measured mean depth is 4.6 feet. Bankfull water
surface slope required is .002 ft/ft, which is equal to the current bankfull slope of
0.002 ft/ft. Mean depth calculations indicate a slightly degrading stream, but the
slope does not need to be adjusted.
Calculated bankfull shear stress is 0.12 pounds per square foot (psf). Based on
the Shields diagram included in Appendix 3, bankfull discharge can move a
particle 7.5 mm in diameter. The Shields diagram shows the relationship of grain
diameter to critical shear stress for a combination of laboratory and field data.
Rosgen has added points to the Shields curve based on empirical data
measured on natural rivers. These points indicate that the Shields curve tends to
underestimate the competence of a river to move a particular particle size for
critical shear stress values between 0.05 and 1.0 psf. Using this revised,
empirically based curve, a shear stress of 0.12 psf corresponds to moving a
particle closer to 25 mm in diameter.
Estimated channel velocities, based on four calculation methods for existing and
proposed conditions, range from 6.1 to 9.0 feet per second (fps). The estimated
velocity selected is 6.2 fps (based on continuity and u/u*) for existing and 5.0 fps
for proposed conditions. This velocity was compared with velocities predicted by
Figure 8.31 of Stream Corridor Restoration Principals, Processes, and Practices
3126/2002 5 EcoLogic Associates
336-855-8108
(Federal Interagency Stream Restoration Workgroup, 1998.) The chart predicts
basic velocities ranging from 4.0 to 6.5 fps depending on sediment load. This
range supports the selected velocity estimate for the existing and proposed
bankfull flow events.
A BEHI bank erosion prediction was calculated for the eroding meander bend at
Station 9+65. Depending on the Stream Bank Erodibility curve used, the
estimated soil loss in 500 feet of that section is 76 tons to nearly 162 tons of soil
per year. This corresponds to 6.2 tons/foot/year (Colorado curve) to 13.1
tons/foot/year (Yellowstone curve) in a 500-foot section.
The stability inventory for the Level 3 assessment indicates that Clear Creek is a
laterally unstable, C4 stream type, which can be restored to a stable C4.
Problems arise due to high bank height ratio and high sediment supply, poor
meander geometry, and irregularly spaced bed features. An additional problem
is poorly defined pools and riffles. Therefore, the restoration design should focus
on restoring stable meander geometry in the prior straightened reach, reducing
the bank height ratio to 1 by creating bankfull benches and laying back banks so
that woody vegetation can be established, and recreating stable bed forms at
regular intervals. These measures will restore stability and diminish sediment
loads caused by eroding banks delivered into the creek.
Natural Channel Design
Aerial photographs from 1951, 1965, 1969, 1970's, 1983, 1993 and 1994 provide
a source of historical information on channel stability, modifications, and
adjustment. Sometime prior to 1951 the channel was straightened, presumably
to maximize agricultural production or facilitate construction of the sanitary
sewer. In the 1969 aerial photo the channel appears to have degraded to an F
stream type, wide and shallow. In 1994, mid channel bars are evident. Also in
1994, there are signs of meanders attempting to form within the eroded banks.
Since 1994, mid-channel bars have evolved and relocated.
The proposed design aims to accelerate stream evolution to a stable C4.
Current slope will be maintained and stable stream meanders will be added.
Other goals of the design are to reduce bank height ratio, improve pools, and
reestablish a woody riparian buffer along the length of the restoration reach.
Structures such as cross vanes and J-hook vanes will be used to control grade
and near bank shear stress. Root wads will be used to protect the outside of
meander bends. In the interest of reducing the bank height ratio, vertical banks
will be laid back to create bankfull benches and to establish a more stable
growing surface.
Tie-ins to existing streambed elevations will be done at the upper end at an
existing riffle located at the property line near 1-26. The downstream tie-in will be
3/26/2002 6 EcoLogic Associates
336-855-8108
above a sanitary sewer crossing upstream of the bridge over Clear Creek Road.
The natural substrate of the stream will not be altered.
Sod mats, available on site, and riparian vegetation will be planted on the new
banks and bankfull benches. Woody riparian vegetation, some of which can be
harvested or transplanted on site, will help establish a healthy riparian buffer
resistant to erosion.
Riparian Buffer Revegetation and Habitat Improvements
Many of the woody plant materials present on site can be harvested and used to
revegetate the restored stream reach. Among the species that can be
propagated or transplanted are black willow (Salix nigra), box elder (Acer
negundo), river birch (Betula nigra), silky dogwood (Corpus amomum), and tag
alder (Alnus serrulata).
Improved bed features, reduced sediment supply, and a revegetated riparian
zone will improve habitat for muskellunge (Esox masquinongy), which is one of
the goals of the French Broad River Basin Water Quality Improvement plan. It
will also improve habitat for NC Natural Heritage Program listed creek-dwelling
amphibians, fish and vascular plants. Some listed species include, but are not
limited to, the Hellbender (Cryptobranchus alleganie6sis), Southern zig-zag
salamander (Plethodon ventralis), Mudpuppy (Necturus maculosus), Blueside
darter (Etheostoma jessiae), Mooneye (Hiodon tergisus), sedges (Caryx spp.),
and Gray's lily (Lilium grays). A complete Natural Heritage species fist is included
at the end of the narrative as is a list of items that will help improve muskellunge
habitat.
Utilities
The only utilities known to exist on site are an overhead power line and a sanitary
sewer line. The sanitary sewer line parallels the left (south) side of the creek.
Both utilities cross the stream just once near Clear Creek Road. At the overhead
power line crossing, woody shrubs should be planted in the riparian zone instead
of trees whose growth could interfere with the power line and require excessive
pruning.
Monitoring and Evaluation Plan
Ecologic Associates will perform physical monitoring of this site for one year
after construction. After that time, a contractor to the WRP will perform
monitoring. Permanent cross sections and photo points will be established and
marked on the as-built drawings. An initial benthic macroinvertebrate sample
was sent to Pennington and Associates, Inc laboratory for analysis. The 77
organisms found represented twenty-five taxa. The EPT index was 5; the biotic
index was 6.27. Benthic survey results are included at the end of this report.

Streamside Vegetation Establishment Plan
Clear Creek, Henderson County
Draft 04Mar02
This site will require transplanting and reuse of on site woody and herbaceous plants and
the addition of new planting material. The work will consist of preparing the planting
areas, furnishing and placing transplants, sod mats, seed, live stakes, bareroot trees,
mulch, fertilizer, soil amendments and anchored ground covering materials. These will
be placed in the streambanks, floodplain, access areas and other areas disturbed by
construction.
Seeding
Seedbed Preparation
On sites where equipment- can be operated safely the seedbed shall be adequately
loosened and smoothed. Foreign material and obstructions should be removed at this
time. Disking and cultipacking or both may be necessary. On sites where equipment
cannot access, the seedbed should be prepared by hand. All surfaces should be scarified
to produce a surface where seed can stay in place until successful germination. If seeding
is done immediately after construction, seedbed preparation may not be required except
on compacted, polished or freshly cut areas.
Fertilizing
Evenly distribute lime and fertilizer over the area to be seeded. Uniformly mix the lime
and fertilizer into the top 3 inches of soil. Apply lime and fertilizer according to soil test
results or at the following rates
Lime 50-100 lbs./ 1000 sq. ft. 1-2 tons/ acre
Fertilizer (10-10-10) 9-12 lbs./ 1000 sq. ft. 400-5001bs./ acre
Sod Mats
Strip and stockpile mats of existing desirable herbaceous vegetation. Insure that several
inches of soil remains attached to the vegetation. The root systems should remain moist
and protected from direct sunlight and drying winds while the vegetation is stockpiled.
These mats will be placed on the bankfull benches and lower slopes of the banks and
anchored in place with stakes. Native sedges and rushes are preferable for use as sod
mats however, fescue and other sod-forming species are acceptable if they are found on
site.
Seeding
Temporary Seeding
Used on recently graded or disturbed sites when erosion and sedimentation control is
required and permanent vegetation cannot be established due to planting season or
logistics. The use of temporary seedings may also be required to stabilize the site prior to
3/4/02 DRAFT 1 EcoLogic Associates, P.C.
the establishment of native or other woody vegetation. Anchored mulch or erosion
control fabrics will be needed to provide surface protection until any vegetation becomes
established.
Fall and Winter Seeding
Oats 2lbs. / 1000 sq. ft. 3 bu. / acre
Rye 31bs. / 1000 sq. ft. 2.5 bu. / acre
Summer Seeding
Sudangrass 1 lb. / 1000 sq, ft. 35-45 lbs. / acre
Browntop Millet 1 lb. / 1000 sq. ft. 30-40 lbs. / acre
Permanent Seeding
Use in combination with woody plantings and transplants on the upslope side of the
riparian planting. Late spring and summer planting is ideal for native perennial warm
season grasses. These grasses should be used when enhancing wildlife habitat is a goal of
the riparian planting. Spring planted seed should be pre-treated with a cold, wet chill
process to maximize germination. Fall plantings should be planted with a lightly sowed
cool season annual grass and forb mixture to hold the soil. Fall plantings do not need the
wet, chill pretreatment. Omit the fertilizer when planting native grasses. A mixture of at
least three native grasses should be used. Competition from sod-forming grasses like
fescue and bluegrass should be removed by either mechanically or chemically
eliminating these before planting the native mixes.
Cool Season Fall or Spring Seedings
Orchardgrass 0.3 lbs. / 1000 sq. ft. 7 lbs. / acre
Big, Little or Broomsedge Bluestem 0.2 lbs. / 1000 sq. ft. 5 lbs. / acre
Eastern Gamma or Switchgrass 0.5 lbs. / 1000 sq. ft. 10 lbs. / acre
A mixture can be made with components at'/a the above rates. Mixtures should include
three or more species. The addition of a legume like white clover (at 1/4 recommended
rate) is advocated when planting a mixture.
Warm Season Summer Seedings
A warm season grass mix similar to the following is commercially available from several
sources. Soil temperature must be above 55°F for proper germination. Seed germination
can be further enhanced by pressing the seed into the seedbed using a roller.
Annual Ryegrass 40%
Big Bluestem 26%
Little Bluestem 14%
Indiangrass 14%
Switchgrass 6%
The recommended rate is 42 pounds of mix / acre.
3/4/02 DRAFT 2 EcoLogic Associates, P.C.
Mulching
Mulching should be performed at the time of seed sowing or within 48 hours of that time.
Weed free grain straw should be applied on seeded areas at a rate of 3 bales per 1000
square feet or 1.5 tons per acre. Mulch should be applied uniformly. Mulch should be
anchored with a mulch crimper, asphalt tackifier, wet down with water or held in place
with appropriate mulch netting.
Woody Plant Installation
Care and Handling
All planting stock should be treated in such a way as to promote the health and vigor of
the plant material and reduce the stress of transplanting and reestablishment. Planting
stock should be stored in a cool and moist environment and protected from direct sun and
drying winds. Roots of bareroot stock shall be kept moist before and during planting
operations. Containerized or potted stock shall be kept moist at all times. Live stakes
should be planted while dormant, which may require refrigeration if the weather is warm.
Damaged roots or shoots should be pruned appropriately during installation.
Transplants
Most woody species found along riparian corridors can be salvaged by transplanting.
Native shrubs and small trees transplant well and will provide mature growth much faster
than other planting material. Even the stumps of many large trees will resprout and
survive proper transplantation. Care should be taken to mark the desirable transplants
along the corridor prior to construction. These plants should be marked with paint or
flagging. These plants are then excavated during the first phase of construction and
placed in a safe location nearby. This site should be sheltered from the afternoon sun and
winds. Periodic checks should be made to see that the soil around the roots remains
moist, they can be watered as needed.
Care should be taken to get as much root ball as possible. It is also advisable to protect
the stems or trunk during this digging and moving procedure. Single trunks should be
temporarily wrapped with thick cloth or other padding if necessary to prevent damage to
the cambium and bark. Multi-stemmed shrubs are often tied together to make them more
easy to handle and less prone to damage. Once the plants have been lifted from their
original position and set in the temporary location the tops should be trimmed.
Depending on the size of the plant and the species one third to one half of the shoot mass
should be removed.
Transplanted material should be placed in their final location as soon as possible or
heeled into a temporary ditch outside of the construction zone until the planting site is
complete. As with other woody plant material the transplants should be re-set so that the
root collar is no deeper then the soil surface, the soil should be firmly compacted around
the rootball and the plant should be watered by thorough soaking. No fertilizer should be
added.
3/4/02 DRAFT 3 EcoLogic Associates, P.C.
Plantini .
Plant rooted stock in a vertical position with the root collar just at the soil surface. The
planting trench or hole must be deep enough and wide enough to permit the roots to
spread out and down without a bending of the primary root structures. Care should be
taken to prevent breaking or damaging the roots or "J" planting of tap root structures.
Make sure that the roots are in contact with soil and no air pockets remain after the soil
has been packed and firmed around the planting. Dormant plantings should be inserted to
a depth that allows them to reach adequate soil moisture.
Species Selection
It is important to plant as much diversity as is available to enhance the wildlife value,
aesthetics and resilience of the corridor and restoration. At a minimum a selection of 10-
12 tree and shrub species should be selected that add to the species diversity that occurs
naturally at this site. The density, effectiveness and ecological function of the woody
plantings will be enhanced by combining canopy trees, understory trees and shrubs in a
mixture that approximates a natural riparian forest type that would occur in an
undisturbed site.
Bare-root and containerized woody species should be planted on the top of the bank
along then length of the riparian corridor. Live stakes and transplanted material should
be used on the lower banks and bankfull benches.
Tree Species Suitable for Clear Creek Restoration
Plant to Plant Spacing 9-9 feet 530 plants / acre initial stock density
Black Willow, Green Ash, Sugar Maple, Sycamore, American Chestnut, :Hackberry,
Sweet Birch, River Birch, Bitternut or Pignut Hickory, Persimmon, Black Walnut,
Cucumber Magnolia, Black Gum, Sourwood, Shortleaf Pine, White Pine, Black Cherry,
Scarlet Oak, Swamp Chestnut Oak, Red Oak, Black Locust, Basswood, Eastern
Hemlock, American Elm, Pawpaw, American Holly
Shrub Species Suitable for Clear Creek Restoration
Plant to Plant Spacing 5-5 feet 1700 / acre initial stock density
Buttonbush, Hazelnut, Elderberry, Red Chokeberry, Silky Dogwood, Spicebush,
Serviceberry, Hawthorne, Highbush Blueberry, Tag Alder, Witch Hazel, Sweet Shrub,
Buttonbush, Sweet Pepperbush, Winterberry, Mountain Laurel, Blackhaw, Yellowroot
Target density of the planting at maturity is 320 trees per acre and 1200 shrubs per acre.
The use of tree shelters or bark wrap may be necessary at Clear Creek to prevent damage
by the resident beaver and deer populations. These shelters can be used on the more
valuable material and the most slow growing and hard to establish species. These
shelters will also accelerate the growth of these woody plants so that they can withstand
3/4/02 DRAFT 4 EcoLogic Associates, P.C.
this herbivore attack. Other anti-browsing chemical deterrents may also be needed to
train these animals to avoid these plantings until they become established.
Live stakes
Live stakes and other cuttings should be dormant at the time of installation. They should
be typically 1/2 to 3/4 inch in diameter and 2-3 feet long. They should have a pointed end at
the bottom to facilitate driving into the bank with a dead-blow hammer. Two thirds of the
stake should be driven into the ground leaving less than 6 inches above the surface. The
stakes will be planted on 3 foot spacing in staggered rows. The number and location of
the live stake rows will be determined by the size and shape of the bank, location of
transplants, sod mats and existing woody vegetation. A minimum of three rows starting
at the foot of the bank and extending to the top of the bank with additional rows as
needed. Damage from the hammering should be clipped off leaving a clean, smooth cut.
Live Stake Species suitable for Clear Creek Restoration
Black Willow
Streamco Willow
Silky Dogwood
Red-Osier Dogwood
The planting should include a mixture of the above species with no more than 40% of any
one species and no less than 15% of the least common.
All trash should be removed from the site after planting and disposed of properly. Once
all plantings are completely installed the site should be left as clean and as natural
looking as possible.

Monitoring Plan for Clear Creek
Hendersonville, NC
Stream restoration in North Carolina requires physical and biological monitoring based on NC
Division of Water Quality criteria. The monitoring period is five (5) years. This time is required
to assess the stability of the restored channel and the survivability of the vegetation planted
during the restoration. The monitoring should be done annually following the completion of
construction. Reports should be sent to the USACE each year and NC DWQ on the first, third
and fifth years.
The Monitoring Report should include the following items from new data collected each year.
The restoration of Clear Creek involves changes to dimension, pattern and profile. Benchmarks
for permanent cross sections, photo points and the top of the restoration reach profile will be
installed during construction. These benchmarks will be referenced during all following data
collection monitoring visits. Use of benchmarks will allow all monitoring data to be comparable.

The minimum requirements of one cross section per 20 bankfull widths could be met with one
cross section. The designers feel that there should be three cross sections to more adequately
monitor the upper, middle and lower sections of the reach since the amount of channel relocation
and in-situ vegetation differs across this range. These cross sections will be located in such a
way as to capture the range of cross sectional geometry installed at this site. One section will be
a riffle section in the middle of the project that will also be the site of monitoring pebble counts,
benthic macro-invertebrate collections and channel geometry diagnostics like width-depth ratio,
entrenchment ratio, bank height ratios and bankfull depth measurements. One riffle cross section
will be at the top of the reach, which will also be a benthic macro-invertebrate collection site.
The third cross section will be in one of the curves to measure stability of a pool.
The pattern of the as-built stream will be documented with measurements of sinuosity, meander
width ratio, and radius of curvature on the newly constructed meanders.
A longitudinal profile will be run through the length of the restoration reach. This profile will
measure the bed, water surface, and bankfull elevations with careful documentation of bed
features. The resultant data should provide facet slopes of the riffles and pools and the spacing
and length of the features documented.
The bed materials will be documented by conducting a pebble count at each reference location.
The d50 and d84 of the riffles will be calculated and reported. A classification pebble count
based on the proportional percentage of riffles and pools will also be conducted and reported.
Riparian Revegetation
Transects or sample blocks will be established for monitoring the riparian vegetation. The
herbaceous sod mat transplants and new seedings will be assessed for establishment,
survivability and durability. The transplants and woody stems will be counted and assessed for
survivability and to document attainment of the success criteria of 320 trees per acre after five
years.
Benthos
Benthic macro-invertebrates will be collected as per the standard methods outlined in the Benthic
Macroinvertibrate Monitoring Protocols for Compensatory Stream Restoration Projects
Technical Guide. At least one member of the collecting team will be a NC-DWQ Certified
Benthic Macroinvertibrate Collector. A NC-DWQ Certified Lab will identify the samples.
Photo Points
Photographs showing the banks and the channel with a scale included will document each
permanent cross section. Photographs will also be taken of the in-stream structures, the
vegetation on the banks and some longitudinal views of the restoration reach.

SITE NAME: Bent Creek DATE: December 12, 2001
SIZE: 500 feet QUADRANGLE: Dunsmore MT
LOCATION: In the Bent Creek Experimental Forest southeast of Asheville, NC. The reach is
4500 feet upstream of Lake Powhatan, just below an old dam ruin. The site within a mile of the
Blue Ridge Parkway which edges the valley on the south (Truckwheel Mt) and east (Grassy
Knob). The reference reach can be reached by parking at the Hardtimes trail head and hiking
upstream or parking along the road in a campsite just above the reach.
SITE SIGNIFICANCE: Type C Reference Reach
GENERAL DESCRIPTION: Bent Creek flows through the bottom of the valley that contains
the Bent Creek Experimental Forest southwest of Asheville, NC. The valley contains many trails
for hiking and mountain bike riding which appear to be heavily used. There is also a large
campground near Lake Powhatan that is open during the summer season. Additionally there are
year round camping facilities available along the road that follows along the north side of Bent
Creek up to the headwaters of the valley at Truckwheel Mountain.
The reach runs through a Type 2 or 3 valley type with moderately steep, gentle, sloping valley
that includes some alluvial deposites. At this point in the valley there are accessible floodplains on
one or both sides of the creek, allowing the development of meander patterns and depositional
features typical of a Type C stream. The end of the reach is constricted against a high bank on the
right with a floodplain only on the left.
The valley contains a young to moderate age tree canopy dominated by tuilp tree, red maple,
pines and hemlocks. The understory along the creek includes witch hazel, ironwood,
rhododendrons, mountain laurel, greenbriar and dog hobble. Herbs along the creek include asters,
seedbox, panicum grasses, violets, wiregrass, sedges, rushes mosses and liverworts.
