Approval of 401 Water Quality Certification with Additional ConditlonSINATER QUALITY
E7t u;2iDSTO?7"%''?„JERE2,
Dear Mrs. Lawhern:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 940 feet of streams for the purpose of
streambank stabilization at the subject properties, as described within your application
received by the N.C. Division of Water Quality (DWQ) on July 18, 2005. After reviewing
your application, we have decided these impacts are covered by General Water Quality
Certification Number(s) 3376 (3376). The Certification(s) allows you to use Nationwide
Permit(s) 37 when issued by the US Army Corps of Engineers (USACE). In addition,
you should obtain or otherwise comply with any other required federal, state or local
permits before you go ahead with your project including (but not limited to) Erosion and
Sediment Control, Non-discharge, and stormwater regulations. Also, this approval to
proceed with your proposed impacts or to conduct impacts to waters as depicted
in your application shall expire upon expiration of the 404 or CAMA Permit.
This approval is for the purpose and design that you described in your application. If
you change your project, you must notify us and you may be required to send us a new
application. If the property is sold, the new owner must be given a copy of this
Certification and approval letter and is thereby responsible for complying with all
conditions. If total fills for this project (now or in the future) exceed one acre of wetland
or 150 linear feet of stream, compensatory mitigation may be required as described in
15A NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in
the attached certification and any additional conditions listed below.

2. Erosion & Sediment Control Practices
Erosion and sediment control practices must be in full compliance with all
specifications governing the proper design, installation and operation and
maintenance of such Best Management Practices in order to protect surface
waters standards:
a. The erosion and sediment control measures for the project must be
designed, installed, operated, and maintained in accordance with the most
recent version of the North Carolina Sediment and Erosion Control Planning
and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and
erosion control measures must be such that they equal, or exceed, the
requirements specified in the most recent version of the North Carolina
Sediment and Erosion Control Manual. The devices shall be maintained on
all construction sites, borrow sites, and waste pile (spoil) projects, including
contractor-owned or leased borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measures must be
designed, installed, operated, and maintained in accordance with the most
recent version of the North Carolina Surface Mining Manual.
d. The reclamation measures and implementation must comply with the
reclamation in accordance with the requirements of the Sedimentation
Pollution Control Act.
3. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian
areas beyond the footprint of the impacts depicted in the Pre-Construction
Notification. All construction activities, including the design, installation, operation,
and maintenance of sediment and erosion control Best Management Practices,
shall be performed so that no violations of state water quality standards, statutes,
or rules occur.
r
4. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Yancey County:
Page 3 of 6
July 25, 2005
Sediment and erosion control measures shall not be placed in wetlands or waters
to the maximum extent practicable. If placement of sediment and erosion control
devices in wetlands and waters is unavoidable, they shall be removed and the
natural grade restored within six months of the date that the Division of Land
Resources has released the project.
5. Certificate of Completion
Upon completion of all work approved within the 401 Water Quality Certification
or applicable Buffer Rules, and any subsequent modifications, the applicant is
required to return the attached certificate of completion to the 401/Wetlands Unit,
North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC,
27699-1650.
6. Construction in this creek and disturbance within a 25-foot trout buffer should be
avoided during the January 1 to April 15 rainbow trout spawning period to avoid
adverse effects of sediment on eggs and larvae. However, Wildlife Resources
Commission will not object to construction of Natural Resources Conservation
Service "urgent and compelling" sites during the spawning period provided these
projects are, to the extent appropriate and practical, constructed by: (1) using flow
diversion structures such as sand bags, (2) placing large-sized rock toes and filter
cloth backing for stabilization sites before backfilling, and (3) excavating new
channel alignments in dry areas. Construction at the other non-"urgent and
compelling" sites should not occur during the spawning period to minimize the
potential adverse effects of multiple construction activities on trout resources in this
creek.
7. Sediment and erosion control measures must be implemented prior to construction
and maintained on the sites to minimize sediment in downstream areas. Seeding for
a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous
cover should occur on all bare soil within five (5) days of ground disturbing activities
to provide long-term erosion control. The projects should be accomplished in stages
instead of leaving large tracts exposed to further storm events. Erosion control
matting should be used in conjunction with appropriate seeding on disturbed soils in
steep slope and riparian areas. Matting should be secured in place with staples,
stakes, or, wherever possible, live stakes of native trees. Straw mulch and tall
fescue should not be used in riparian areas. In addition, because of an anticipated
difficulty in establishing ground cover during the winter, reseeding should be
conducted, as necessary, in the spring-time with a native annual and perennial seed
mix with a temporary nursery crop of wheat, millet or other grain.
Yancey County:

8. Only clean, large, angular rock, large woody material, or other natural stream design
materials and techniques should be used for bank stabilization. Rock should not be
placed in the stream channel in a manner that constricts stream flow or that will
impede aquatic life movements during low flow conditions. Filter cloth should be
placed behind large rock that is used for bank stabilization. Properly designed rock
vanes should be constructed wherever appropriate on bank stabilization and
channel realignment stream reaches to improve channel stability and to improve
aquatic habitat. Root wads should be installed low enough in the bank so that a
significant portion (at least one-third) the root wad is inundated during normal flows.
9. The channel should be restored to a more stable condition. However, under no
circumstances should river rock, sand or other materials be dredged from the stream
channel under authorization of this permit except, if necessary, in the immediate
vicinity of the eroding banks for the explicit purpose of anchoring stabilizing or
flow/grade control structures or for reestablishing the natural and more stable stream
channel dimensions. Stream bed materials are unstable in flowing-water situations
and are unsuitable for bank stabilization. In stream dredging has catastrophic effects
on aquatic life and disturbance of the natural form of the stream channel can cause
downstream erosion problems. The natural dimension, pattern, and profile of the
stream upstream and downstream of the permitted area should not be modified by
widening the stream channel or changing its depth.
10. Stabilization measures should only be applied on or near existing erosion sites,
leaving other stable stream bank areas in a natural condition. Grading and
backfilling should be minimized and tree and shrub growth should be retained where
possible to ensure long term availability of stream bank cover for aquatic life and
wildlife. Backfill materials should be obtained from upland sites except in cases
where excess stream bed materials are available. Berms should not be permitted
because they block the floodplain, constrict and accelerate flood flows, and often fail
and sometimes impede drainage during large flood events.
11. Repairs to eroded banks should be conducted in a dry work area where possible.
Sandbags or other clean diversion structures should be used where possible to
minimize excavation in flowing water. Channel realignments should be constructed
by excavating the new channel from downstream to upstream before connecting it to
the old channel.
12. Heavy equipment should be operated from the bank whenever possible. All
mechanized equipment operated near surface waters should be inspected and
maintained regularly to prevent contamination of stream waters from fuels,
lubricants, hydraulic fluids or other toxic materials. Equipment used in stream
channel must be clean, new or low hour equipment.
13. Disturbed stream banks and a 25-foot vegetated zone, or the widest width that is
practical under the site conditions, should be restored where possible along the
construction sites to natural riparian conditions with native trees and shrubs (e.g.,
silky dogwood, rhododendron, dog hobble, red maple, silky willow, tag alder, black
willow, sycamore) to provide long-term bank stability and stream shading. Note,
silky dogwood, silky willow and black willow can be planted as live stakes collected
during the dormant growing season. Cuttings should be randomly planted on four
(4) foot centers from the waters edge to the top of the bank. Trees should be planted
on ten (10) to twelve (12) foot centers. Stream banks in these areas should also be
seeded with a native annual and perennial seed mix with a temporary nursery crop
of wheat, millet or other grain.
14. If pasture along the stream
outside of the riparian zone
areas.
15. Diffuse Flow
Yancey County:

is to be used for grazing, a fence must be constructed
and the stream to prevent livestock from entering these
All constructed stormwater conveyance outlets shall be directed and maintained
as diffuse flow at non-erosive velocities through the protected riparian zones
such that it will not re-concentrate before discharging into a stream. If this is not
possible, it may be necessary to provide stormwater facilities that are considered
to remove nitrogen. This may require additional approval from this Office.
16. Riparian Zone Replanting
Replanting of vegetation within disturbed areas located within 30 feet of the
streambank associated with any land disturbing activity, repair, replacement
and/or maintenance must be done in a manner consistant with the Guidelines
for Riparian Buffer Restoration immediately following construction. (Please
see attached.)
45. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained
jurisdictional wetlands, waters and protective woody riparian zones in order to
assure compliance for future wetland, water and buffer impact. These
mechanisms shall be put in place prior to impacting any wetlands, waters and/or
buffers approved for impact under this Certification Approval and Authorization
Certificate. A sample deed notification can be downloaded from the
401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of
the sample deed notification may be modified as appropriate to suit to this
project.
17. Turbidity Standard
The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be
exceeded as described in 15 A NCAC 2B. .0200. Appropriate sediment and
erosion control practices must be used to meet this standard.
18. No Sediment and Erosion Control Measures in Wetlands
Sediment and erosion control measures shall not be placed in wetlands or waters
to the maximum extent practicable. If placement of sediment and erosion control
devices in wetlands and waters is unavoidable, they shall be removed and the
natural grade restored within six months of the date that the Division of Land
Resources or locally delegated program has released the project.

Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
Land use in the vicinity of the proposed project site consists of agricultural uses, including
trout farms. This portion of Cane River was heavily impacted during Tropical Storms
Fiances and Ivan. In this location, the stream is clogged with woody and non-native debris,
reducing the hydraulic capacity of the channel. In the location of the proposed bank repair
the river has shifted approximately 150 feet to the west of the original channel. Tivo trout
ponds were destroyed, and the relocated channel threatens the stability of existing structures.
8. Describe the overall project in detail, including the type of equipment to be used:
This Pre-Construction Notification form addresses only one area of streambank stabilization
and relocation on DSR 22. DSR 22 covers damage fr oin Tropical Storms Frances and Ivan
Jrorri the HIVY 197 bridge at Murchison to the confluence of the Cane River and Cattail Creek.
The area addressed by this submittal is entirely located on the parcels shown on Figure 2, and
detailed in Tables 1 and 2.
The location of the streambank repair area is provided ill Figure 2. Representative typical
photographs of dainage for the streambank stabilization area are included as Figures 3-6.
Repairs for° the area are detailed in Figures 3A-6A. Target cross-section for° this section is
included in Figure 7. Typical in-stream structure detail is included in Figure 8.
Since the entire site is located on agricultural land, a formal approval of the Erosion and
Sediment Control Plan elements of this proposal is not required, nor is a Trout Waiver required.
Work will take place on approximately 940 linear feet of channel.
The primary issue to be addressed at the Trout Pond reach is channel avulsion into the ponds
during the September 2004 floods. The rnovenrent of the channel to the west side of the valley
has removed the trout ponds and has eroded portions of the road which leads along the side of
the river to a set of rental houses. There is also a power line, which now has one pole on what is
now an island in the middle of the wide channel.
The primary constraint in this location is the technical difficulty inherent in stabilizing a channel
that has meandered to the extent that the Cane River has in this location. The streanrbed loses
significant grade as it drops into the aligrunent of the former ponds. To re-align the stream to
the east (river-right), significant amounts of fill would have to be placed to buildup the
ponds/current stream channel. These sediments would be prone to erosion and transport duriiig
high flows.
All work will be per formed as per conversations between Altainont Environnierntal, US Arnry
Corps of Engineers, NC Wildlife Resources Commission, and on-site consultation with the US
Fish and Wildlife Service personnel on other EWP sites in this watershed. Work will include
streambank stabilization in the area described below as well as localized removal of organic and
mineral debris and streambank re-vegetation.
Cane River is classified as `WSII', `Trout' waters and High Quality Waters (HQUI) throughout
the project area. No listed species or their habitats occur in this area according to the US Fish
and Wildlife Service response to the EWP Environmental Checklist on February 2, 2005.
The overall goals of work at this location are to
1. Stabilize the channel in the post flood condition, directing low flows to river-right while
allowing storm flows to engage the river left channel.
2. Re-establish a larger channel ort the east (right) side of the inset valley. The channel
geometry and cross-sectional area will be based on regional curve analysis and evaluation of
relatively undisturbed portions of the Cane River upstream and downstream of the site.
3. Provide a medium to high flow channel along the current path of the main channel.
4. Protect the unpaved access road along the west side of the valley.
To accomplish these goals, it will be necessary to utilize a combination of rock rip-rap,
bioengineering, in-stream structures, and channel bed excavation.
Property owner information for all proposed work areas is included in Table 1 and Table 2.
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are threatening
structures. The proposed actions are not intended to enhance existing conditions or restore the
stream reaches using natural channel design techniques. Such activities would require detailed
engineering evaluation and design, which are beyond the intent of the EWP program.
Equipment used to accomplish the above tasks includes: one or more 15 ton dump trucks, one
or more hydraulic track mounted excavators with thumb, one or more dozers with a six-way
blade; and chainsaws.
Establishment of vegetation on the disturbed channel banks will be necessary in some locations
in the vicinity. Vegetation establishment will consist of a combination of hydroseeding and live
staking.
A primary concern for° the excavation of channel bed materials is the impact to turbidity within
the Cane River. It may be possible to separate excavators from flow via the use of temporary
berms, pipes, and water pumps. However, given the significant quantities of water in the system,
and the high permeability of soils in this reach, excavating the charnel bed in this location with
the excavators out of the water is unpractical. Therefore, the work will be sequenced without
attempt to separate the equipment from flowing water, and attention will be focused on an
efficient work pattern that will limit the time necessary for equipment to be in the water. The
following construction sequence will be utilized.
The total area of impact within the active channel banks in this reach will be approximately 4.0
acres. The volurue of cut and fill will be approximately balanced in this reach as any excavation
f om the river-right portion of the channel will be used to re-contour the river-left portion of the
channel.
At all areas the work will proceed from downstream to upstream to reduce sediment loading. All
staging areas will be less than half an acre in size. TVork will proceed as follows at each work
area (as applicable):
1. Flag the work limits.
2. Mark live trees and shrubs to be protected
3. Construct temporary construction erntrarncelexits, where necessary.
4. Install sediment fence around staging areas.
5. Grade new roadbed and place rock in channel. Stabilize with coir° and plantings.
6. Install sand bag berm to direct all flow into the western (river-left) channel.
7. Install second sand bag berm at the downstream end of the eastern channel to prevent
backwater from the western channel.
8. Excavate river-right bar and river-right channel.
9. Modem sand bag berm to direct flow to the right.
10. Install in-stream structure. Structure will consist of a modified "TV" weir that will allow
flows to engage the river-left channel at higher stages.
11. At the end of each workday install temporary erosion control fabric or matting on exposed
soil and secure using removable stakes or sandbags.
12. During construction, place loge boulders at the toe of repaired streambarnks where
necessary.
13. Fill and compact behind boulders andlor coir logs. Cover with topsoil, install erosion
control rnat, and seed. Permanent erosion control mats will be constructed of fiber or a coir
fiber mixture fabric for maximum erosion protection, vegetation establishment assistance,
and for minimal impact on wildlife.
14. Inspect and maintain repairs.
A site-specific engineering design based on a specific storm event was not connpleted because
the EiVP program is not intended to fund stream restoration design or construction work
Rather, the EIVP progran is designed to quickly stabilize eroding stream banks to prevent on-
going erosion, sedimentation and possible loss of property or life. Because natural channel
design methods are beyond the scope of the ETVP program, published literature values were
consulted in order to specify the bank stabilization and erosion control materials and methods
described in this document. For example, we have specified that falter cloth will be placed
behind large rock used for strearnbank stabilization or for in-stream structures to increase the
stability of the repair measures and minimize sediment loading to the stream. Clean, large,
angular rock, coir logs, large woody material, and natural fiber erosion control mats will be
used for strearnnbarnk stabilization.
Once site construction has ceased, the banks of the stabilized channel will be seeded with a
native foodplain seed mix and the high stress areas will be lined with erosion control (EC)
matting to ensure bank stability. Furthermore, sod matting will be grubbed on-site and used
(when available) to line the near bank regions of the constructed/stabilized channel to provide
immediate stability. Live stakes and matting staples will be used to secure the EC fabric/sod-
matting in these high stress areas. Broadcast seeding rates will be as specified from the local
nursery, generally I5-20 lbs/acre depending on species. With landowner permission, native
shrub and tree species will be planted throughout the project reach at a rate of 320 stems/acre,
securing near bank areas and providing future shading to the channel. Existing woody
vegetation will be preserved to minimize project impacts. The following steps will be observed
with respect to vegetation:
1. Exposed soil will be covered with erosion control matting at the end of every workday.
Mats will be secured using removable stakes.
2. The project riparian zone and/or buffer areas will be re-vegetated with a combination of
native trees, shrubs and herbs/grasses. All disturbed areas will be seeded with a temporary
native grass mixture immediately following completion of the work in those areas. Straw
mulch and tall fescue will not be used in riparian areas.
3. When possible sod will be taken ftoin adjacent areas (with landowner permission) and
placed on exposed soil to provide immediate stabilization within five days of ground
disturbing activities.
4. If sod is not available on-site temporary seeding will occur on all bare soil within five days
of ground disturbing activities to provide long-term erosion control. If sod is used, the bare
area left after removal of sod will be planted.
5. Re-seeding will be conducted, as necessary, with a native annual and perennial seed mix
with a temporary nursery crop of wheat, millet, or other grain.
6. Woody vegetation will be planted during the normal growing season assuming landowner
permission.
In addition to construction sequencing, we propose to utilize standard Best Management
Practices (BMPs) such as those described in the North Carolina Erosion and Sediment Control
Manual. We anticipate that some combination of the following BMPs will be utilized.
1. Sediment Fence. Sediment fence will be utilized to delineate the work materials staging
area and refueling areas.
2. Temporary Berms. Berms constructed of sand bags, soil, straw bales, or geotextile may be
utilized to separate flowing water from the work site. These berms shall be constructed to
avoid and minimize changes to the velocity and sediment transport capacity of the flow of
water through the constriction.
3. Erosion Control Fabric. Typically, 700-series Coir Cloth will be utilized along channel
banks to provide immediate shear strength after fine grading is complete. Coir cloth has
distinct advantages over synthetic materials because it will: (1) allow planting'of grass seed
and live stakes, and (2) will degrade over tune.
4. Veizetation. In general, tlvo types of vegetation will be used to provide short- and long-term
stability for disturbed areas. Grass seed, applied with straiv and tackifrer in a hydroseed
slurry is intended to provide short-term (this year) stability. Live stakes are intended to
develop into a riparian vegetation corsurrunity over tune to stabilize the channel through tune
and a range ofjlows.
5. Bio-Bags. A pump and geotextile bag system could be utilized to de-1vater active
construction areas. Turbid water is purrrped out of the job site, through the frlter^ bag onto an
approved discharge location.
6. "Dirty" Rip-Rap. In addition to placing rock, in some instances we will also backfrll a
portion of the newly-rocked surface with finer materials that could support livestakes
9. Explain the purpose of the proposed work:
The work being described is exigency work under the Emergency TVatershed Protection program
to protect existing property and structures. Streanrbank and channel stabilization will also
prevent fu rther erosion and sedimentation to the Cane River resource.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,

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.
On behalf of Yancey County, Altaniont will provide contractors engaged in the implementation of
this work both written and verbal instructions of all impact avoidance statements provided below.
All heavy equipment will be kept out of the stream channel during streambank stabilization and
stream relocation work, except where absolutely necessary to install bank stabilization measures.
Disturbance of channel bottom and banks and equipment access areas shall be held to the
minimum necessary to allow for bank stabilization and debris removal sufficient to restore the
hydraulic capacity of the stream channel. Temporary grass cover shall be planted on all bare soil
within 5 days of ground disturbing activities. Provided landowners give permission, herbaceous
and woody shrub and tree vegetation will also be installed on the riverbank upon completion of
bank stabilization work Yancey County will provide a site Manager to routinely inspect and
supervise contractor work to help ensure impact avoidance instructions are being followed.
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
Pennits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic enviroiunent 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
10
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://l12o.eiir.state.nc.us/ncwet]ands/strmv

River Basin map is available at http://l12o.enr.state.ne.us/admii-i/maps/.)
Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application:
Land use in the vicinity of the proposed project site consists of agricultural uses, including
trout fauns. This portion of Cane River was heavily impacted during Tropical Storms
Frances and Ivan. In this location, the stream is clogged with woody and non-native debris,
reducing the hydraulic capacity of the channel. In the location of the proposed bank repair
the river has shifted approximately 150 feet to the west of the original channel. Two trout
ponds were destroyed, and the relocated channel threatens the stability of existing structures.
8. Describe the overall project in detail, including the type of equipment to be used:
This Pre-Construction Notification form addresses only one area of strearnbank stabilization
and relocation on DSR 22. DSR 22 covers damage fr-orrn Tropical Storms Fiances and Ivan
fr-onn the HWP 197 bridge at Murchison to the confluence of the Cane River and Cattail Creek.
The area addressed by this submittal is entirely located on the parcels shown on Figure 2, and
detailed in Tables I and 2.
The location of the strearnbank repair area is provided in Figure 2. Representative typical
photographs of damage for the streanbannk stabilization area are included as Figures 3-6.
Repairs for the area are detailed in Figures 3A-6A. Target cross-section for this section is
included inn Figure 7. Typical in-stream structure detail is included in Figure 8.
Since the entire site is located on agricultural laud, a formal approval of the Erosion and
Sediment Control Plan elements of this proposal is not required, nor is a Trout Waiver required.
Work will take place on approximately 940 linear feet of channel.
The primary issue to be addressed at the Trout Pond reach is channel avulsion into the ponds
during the September 2004 floods. The movement of the channel to the west side of the valley
has removed the trout ponds and has eroded portions of the road which leads along the side of
the river to a set of rental houses. There is also a power line, which now has one pole on what is
now an island in the middle of the wide channel.
The primary constraint in this location is the technical difficulty inherent in stabilizing a channel
that has meandered to the extent that the Cane River has in this location. The strearnbed loses
significant grade as it drops into the aligrurnent of the fornner ponds. To re-align the strean to
the east (river-right), significant amounts offill would have to be placed to build up the
ponds/current stream channel. These sediments would be prone to erosion and transport dining
high flows.
All work will be performed as per conversations bettiveen Altarnnornt Ernvironnnental, USArmy
Corps of Engineers, NC Wildlife Resources Col)nmissiOn, and on-site consultation with the US
Fish and Wildlife Service personnel on other ETVP sites in this watershed. Work will include
strearnbarnkstabilizalion in the area described below as well as localized removal of organic and
mineral debris and strearnbank re-vegetation.
Cane River is classified as `WSII', `Trout' waters and High Quality Waters (HQIJ9 throughout
the project area. No listed species or their habitats occur in this area according to the US Fish
and Wildlife Service response to the EWP Environmental Checklist on February 2, 2005.
The overall goals of work at this location are to
1. Stabilize the channel in the post flood condition, directing low flows to river-right while
allowing storin flows to engage the river left channel.
2. Re-establish a larger channel on the east (right) side of the inset valley. The channel
geometry and cross-sectional area will be based on regional curve analysis and evaluation of
relatively undisturbed portions of the Cane River upstream and downstream of the site.
3. Provide a medium to high flow channel along the current path of the main channel.
4. Protect the unpaved access road along the west side of the valley.
To accomplish these goals, it will be necessary to utilize a combination of rock rip-rap,
bioengineering, in-stream structures, and channel bed excavation.
Property owner information for all proposed work areas is included in Table 1 and Table 2
The work addressed in this application is intended to improve the post flood hydraulic capacity
of the stream reaches discussed and stabilize severely eroded streambanks that are threatening
structures. The proposed actions are not intended to enhance existing conditions or restore the
stream reaches using natural channel design techniques. Such activities would require detailed
engineering evaluation and design, which are beyond the intent of the EWP program.
Equipment used to accomplish the above tasks includes: one or more 15 ton dump trucks, one
or more hydraulic track mounted excavators with thumb, one or more dozers with a six-way
blade; and chainsaws.
Establishment of vegetation on the disturbed channel banks will be necessary in some locations
in the vicinity. Vegetation establishment will consist of a combination of hydroseeding and live
staking.
A primary concern for the excavation of channel bed materials is the impact to turbidity within
the Cane River. It may be possible to separate excavators fi°oin flow via the use of temporary
berms, pipes, and water pumps. However, given the significant quantities of water in the system,
and the high permeability of soils in this reach, excavating the channel bed in this location with
the excavators out of the water is impractical. Therefore, the work will be sequenced without
attempt to separate the equipment from flowing water, and attention will be focused on an
efficient work pattern that will limit the time necessary for equipment to be in the water. The
following construction sequence will be utilized.
The total area of impact within the active channel banks in this reach will be approximately 4.0
acres. The volume of cut and fill will be approximately balanced in this reach as any excavation
4
fi-om the river-right portion of the channel will be used to re-contour the river-left portion of the
channel.
At all areas the work will proceed from downstremn to upstream to reduce sediment loading. All
staging areas will be less than half an acre in size. TJ7ork will proceed as follolvs at each work
area (as applicable):
1. Flag the work limits.
2. Mark live trees and shrubs to be protected
3. Construct temporary construction entrancelexits, where necessary.
4. Install sediment fence around staging areas.
5. Grade new roadbed and place rock in channel. Stabilize with coin and plantings.
6. Install sand bag berm to direct all flow into the western (river-left) channel.
Z Install second sand bag berm at the downstream end of the eastern channel to prevent
backivater from the western channel.
8. Excavate river-right bar and river-right channel.
9. Modify sand bag berm to direct flow to the right.
10. Install irn-str•eart structure. Structure will consist of a modified "TV" weir that will allow
flows to engage the river-left channel at higher stages.
11. At the end of each workday install temporary erosion control fabric or matting on exposed
soil and secure using removable stakes or sandbags.
12. During construction, place large boulders at the toe of repaired streanbanks where
necessary.
13. Fill and compact behind boulders andlor coir logs. Cover with topsoil, install erosion
control mat, and seed. Permanent erosion control mats will be constructed offiber or a coir
fiber mixture fabric for maximum erosion protection, vegetation establishment assistance,
and for rrninirnal impact on wildlife.
14. Inspect and maintain repairs.
A site-specific engineering design based on a specific storm event was not completed because
the ETVP program is not intended to fund stream restoration design or construction work
Rather, the ETVP program is designed to quickly stabilize eroding stream banks to prevent on-
going erosion, sedimentation and possible loss ofproperty or life. Because natural channel
design methods are beyond the scope of the ETVP progran, published literature values tivere
consulted in order to specify the bank stabilization and erosion control materials and methods
described in this document. For example, we have specified that falter cloth will be placed
behind large rock used for streanbank stabilization or for in-stream structures to increase the
stability of the repair measures and minimize sediment loading to the stream. Clean, large,
angular rock, coir logs, large woody material, and natural fiber erosion control mats will be
used for streanbank stabilization.
Once site construction has ceased, the banks of the stabilized channel will be seeded with a
native floodplain seed mix and the high stress areas will be lined with erosion control (EC)
matting to ensure bank stability. Furthermore, sod matting will be grubbed on-site and used
(when available) to line the near bank regions of the constructed/stabilized channel to provide
immediate stability. Live stakes and matting staples will be used to secure the EC fabric/sod-
matting in these high stress areas. Broadcast seeding rates will be as specified fi°om the local
nursery, generally 15-20 lbs/acre depending on species. With landowner permission, native
shrub and tree species will be planted throughout the project reach at a rate of 320 sterns/acre,
securing near bank areas and providing future shading to the channel. Existing woody
vegetation will be preserved to minimize project impacts. The following steps will be observed
with respect to vegetation:
1. Exposed soil will be covered with erosion control matting at the end of every workday.
Mats will be secured using removable stakes.
2. The project riparian zone and/or buffer areas will be re-vegetated with a combination of
native trees, shrubs and herbs/grasses. All disturbed areas will be seeded with a temporary
native grass mixture immediately following completion of the work in those areas. Straw
mulch and tall fescue will not be used in riparian areas.
3. When possible sod will be taken fi°om adjacent areas (with landowner permission) and
placed on exposed soil to provide immediate stabilization within five days of ground
disturbing activities.
4. If sod is not available on-site temporary seeding will occur on all bare soil within five days
of ground disturbing activities to provide long-term erosion control. If sod is used, the bare
area left after removal of sod will be planted.
5. Re-seeding will be conducted, as necessary, with a native annual and perennial seed mix
with a temporary y nursery crop of wheat, millet, or other grain.
6. Woody vegetation will be planted during the normal growing season assuming landowner
permission.
In addition to construction sequencing, we propose to utilize standard Best Management
Practices (BMPs) such as those described in the North Carolina Erosion and Sediment Control
Manual. We anticipate that some combination of the following BMPs will be utilized.
1. Sediment Fence. Sediment fence will be utilized to delineate the work materials staging
area and refueling areas.
2. Tennt)orary Berms. Berms constructed of sand bags, soil, straw bales, or geotextile may be
utilized to separate flowing water fmn the work site. These berms shall be constructed to
avoid and minimize changes to the velocity and sediment transport capacity of the flow of
water through the constriction.
3. Erosion Control Fabric. Typically, 700-series Coir Cloth will be utilized along channel
banks to provide immnediate shear strength after fine gradhig is complete. Coir cloth has
distinct advantages over synthetic materials because it will: (1) allow plarzting'ofgrass seed
and live stakes, and (2) i-vill degrade over time.
4. Vegetation. In general, two types of vegetation will be used to provide short- and long-term
stability for disturbed areas. Grass seed, applied with straw and tackifier in a hydroseed
slurry is intended to provide short-term (this year) stability. Live stakes are intended to
develop into a riparian vegetation community over time to stabilize the channel through tune
and a range offlows.
5. Bio-Bats. A pump and geotextile bag system could be utilized to de-water active
construction areas. Turbid ivater is pumped out of the job site, through the filter bag onto an
approved discharge location.
6. "Dirty" Rip-Rap. In addition to placing crock, in some instances we 1vill also backfill a
Portion of the newly-rocked surface with finer materials that could support livestakes
9. Explain the purpose of the proposed work:
The work being described is exigency work under the Emergency [Watershed Protection program
to protect existing property and structures. Streambank and channel stabilization 1vill also
prevent further erosion and sedimentation to the Cane River resource.
