Madison County
Post Office Box 579
Marshall, NC 28753
Subject Property: South Fork Big Pine Creek EWP (DSR -1)
Approval of 401 Water Quality Certification with Additional Conditions
Dear Mr. McDevitt:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 1,800 feet of streams for the purpose of
streambank stabilization and woody debris removal / trash removal at the subject
properties, as described within your application received by the N.C. Division of Water
Quality (DWQ) on August 16, 2005. After reviewing your application, we have decided
that the impacts are covered by General Water Quality Certification Number(s) 3367
(3367). 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 that you described in your application. (Nothing in this
approval should be interpreted as giving permission to remove bedload material
form the existing channel, nor allowing for the construction of berms which
would not allow the stream access to it's floodplain.) If you change your project
beyond the approval here, 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.
The Additional Conditions of the Certification are:

1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific
and general conditions of this Certification (or Isolated Wetland Permit) are met.
No other impacts are approved including incidental impacts:
Amount
Approved (Units) Plan Location or Reference
Stream 1,800 feet South Fork Big Pine Creek
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.
Madison County:
Page 3 of 6
September 6, 2005
4. No Sediment & Erosion Control Measures w/n Wetlands or Waters
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 October 15 to April 15 trout spawning period to avoid adverse
effects of sediment on eggs and larvae, where applicable. 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.
Madison County:

September 6, 2005
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
Madison County:

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 is to be used for grazing, a fence must be constructed
outside of the riparian zone and the stream to prevent livestock from entering these
areas.
15. Diffuse Flow
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 25 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.)
17. 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
401NWetlands 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.
18. 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.
19. 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.

EWP-Madison County, North Carolina
DSR 1- South Fork Big Pine Creek
Sites 1, 29 39 7,&8
French Broad River Basin
Scope of Work
These sites are along South Fork Big Pine Creek, from the confluence with North Fork Big Pine
Creek upstream along South Fork Road (SR 1158) for 1.9 miles. All of these sites have eroding
stream banks, most often due to the lack of stabilizing tree roots, channels aggraded with cobble
and sand, and in some cases new channel alignments due to the fall 2004 floods. At these sites
we will be installing structures to protect the stream banks and adjust the channel thalwag so that
future deposition does not occur. We will also be returning the channel to its pre-flood
alignment. Site specific plans, which are attached, show site location, existing conditions and
planned repairs. All repair work is being proposed under the Emergency Watershed Protection
Program that Madison County is administering. Questions relative to this package should be
directed to Buck Engineering's Micky Clemmons, at 828.350.1408 or 828.734.7445.

10. Describe the overall project in detail, including the type of equipment to be used: Specific
repair activities for each site are provided in the site repair plans which are attached. Repair
activities proposed for these sites include: removing aggraded rocky debris from the channel
to return the channel to the proper dimension and profile installing vane structures to protect
unstable stream banks, grading bankfull benches in areas where the channel can no longer
access its floodplain, removing unstable woody debris, and grading and planting unstable
stream banks to provide long-term stability. This work will require the use of a trackhoe
with hydraulic thumb and a dump truck to haul boulders to the site and to remove rock debris
from the site. A bulldozer may be needed for some of the grading work.
11. Explain the purpose of the proposed work: This work is being done as part of the
Emergency Watershed Protection program that counties impacted by 2 Hurricanes in the Fall
of 2004 are carrying out. The purpose of the work is to repair damaged stream reaches that
are unstable and continuing to cause loses of personal and public property, and to public
resources by degrading water quality and other natural resources.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. The applicant must also
provide justification for these impacts in Section VII below. All proposed impacts, permanent
Page 3 of 9
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must be shown on a
delineation map, whether or not impacts are proposed to these systems. Wetland and stream
evaluation and delineation forms should be included as appropriate. Photographs may be
included at the applicant's discretion. If this proposed impact is strictly for wetland or stream
mitigation, list and describe the impact in Section VIII below. If additional space is needed for
listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Impacts from this work will be
minimized whenever possible. However, to accomplish these needed repairs impacts may be
realized from temporary increased turbidity, removal of aggraded bed material and temporary
loss of herbaceous vegetation. Long-term impacts will be an increase in stream bank
stability, stable dimension and profile and improved vegetative cover.
2. Individually list wetland impacts below:

stabilization activities (cement wall, rip-rap, crib wall, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is
proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included.
** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest
downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at
www.usgs.gov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com,
www.mapquest.com, etc.).

List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging,
flooding, drainage, bulkheads, etc.
5. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.):
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.):
Size of watershed draining to pond: Expected pond surface area:
Page 5 of 9
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.
Access to each site will be over the most stable route possible and movement of vehicles over
access routes will be minimized. Wherever possible equipment work will be done from the
stream bank. Operating _equipment within the channel will be done when this is the only way to
accomplish needed work. Excavated material will be moved directly to trucks for hauling to
disposal sites when it will not be used on site. When excavated material will be used on site it
will be handled as few times as possible. Work at each site will be accomplished as quickly as
possible and the site will be stabilized with erosion control matting and seeding within 5 days of
site completion. Trees will be planted during the next dormant season. Equipment leaking any
fluids will not be used and if leaks occur during construction the equipment will be replaced or
repaired immediately. Sediment and erosion control measures including silt fence stoned
entrances, protected stock pile areas, diversions and check dams will be employed to minimize
sediment movement off site.
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
http://h2o.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.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to deterrnine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): N/A

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ? No ® If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* (Impact
feet) Multiplier Mitigation
1 3
2 1.5
Total
/-one 1 extends out 3U feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or.0260.

The following list of DSR's were reviewed by Jim Errante, NRCS Cultural Resources Specialist (CRS). A
literature search for each planed practice location took place in the Archaeological Map room of the NC Office
of State Archaeology. Each location was reviewed for the potential of NRCS planned activities to effect
cultural resources (CR's). In addition, photographs of the APE's were often reviewed and discussions were
held with knowledgeable field office staff and/or the engineering staff in order to determine the potential of
planned activities to effect CR's at each EWP practice location. Each practice location received a ranking of
a low, medium or high potential to effect CR's.
All EWP practice locations receiving a medium or high ranking to effect cultural resources were
archeologically surveyed by the NRCS CRS. Archaeological survey procedures included reconnaissance
survey of all visible soils in the area including river bank profiles and shovel testing. All shovel tested soils
were screened through %4 inch hardware mesh. The following Excel file list of EWP locations includes a
statement describing the results of this survey work. The NRCS CRS maintains the field work details of the
archaeological survey at each APE. Any questions concerning the results of these survey results as listed
below should contact the NRCS CRS for further explanation.

We have reviewed the site locations and discussed the EWP measures with design consultants at
Buck Engineering. The following comments are provided in accordance with the Migratory Bird
Treaty Act (16 U.S.C. 703, et seq.); section 7 of the Endangered Species Act of 1973, as
amended (16 U.S.C. 1531-1543) (Act); and the Fish and Wildlife Coordination Act (16 U.S.C.
661 et seq.).
Emergency Watershed Protection. Flood damage to stream banks and channels occurred in
the watersheds of several streams in western North Carolina from extreme flows during and
following extensive rainfall associated with two storms in September 2004. Assistance to North
Carolina counties is proposed under the EWP Program of the Natural Resources Conservation
Service (NRCS). According to 7 CFR, Part 624.2, "The objective of the EWP program is to
assist in relieving imminent hazards to life and property from floods and the products of erosion
created by natural disasters that cause a sudden impairment of a watershed."
We previously provided the following recommendations to minimize and avoid potential adverse
impacts to fish and wildlife resources:
Stream Channel and Bank Reconstruction/Restoration Activities. These
guidelines are the criteria that we believe need to be met in order to minimize
environmental impacts. If an applicant agrees to follow these guidelines, this
letter may serve as evidence of consultation under the FWCA, and further
consultation with us under the FWCA will not be necessary (unless the NRCS
desires additional input).
• Recommended Native Plant Species for Stream Restoration in North Carolina.
We recommend the use of native plants in restoration and erosion-control
efforts. This document provided a list of suitable species and sources.
We found the maps helpful for pinpointing the location of each proposed EWP project site. We
do note that each of the sites is located within the French Broad River basin.
Endangered Species. According to our records and a review of the information you provided,
no listed species or their habitats occur on the sites described. We concur with the determination
that the activities proposed at these sites will not affect endangered or threatened species or their
habitats. Therefore, we believe the requirements under section 7 of the Act are fulfilled.
However, obligations under section 7 of the Act must be reconsidered if. (1) new information
reveals impacts of this identified action that may affect listed species or critical habitat in a
manner not previously considered, (2) this action is subsequently modified in a manner that was
not considered in this review, or (3) a new species is listed or critical habitat is determined that
may be affected by the identified action.
If we can be of assistance or if you have any questions, please do not hesitate to contact
Mr. Mark A. Cantrell of our staff at 828/258-3939, Ext. 227. In any future correspondence
concerning this project, please reference our Log Number 4-2-05-236.

DSR 1- South Fork Big Pine Creek - Site 1
French Broad River Basin
3 square mile watershed
35.7833°N, 82.810601V
Scope of Work
This site is on South Fork Big Pine Creek off of South Fork Road, SR 1158. It is 0.1
miles upstream from its confluence with Big Pine Creek. The adjoining landowners are
Bernard & Patricia Bradach, Lois & Lyda Wyatt and Wade Massey of Madison County.
During the hurricanes of 2004, the stream channel upstream of the culverts under the
driveway filled with coarse sediment and deposited sediment in the upstream channel for
approximately 200 feet. With the channel blocked, the resulting overland flow eroded a
new channel in the adjacent hay field. This deposition and the resulting change of stream
gradient have induced bank erosion upstream of the filled channel. Downstream of the
culverts, there is significant left bank erosion for approximately 250 feet, followed by
right bank erosion for another 100 feet. Further downstream near the barn, the banks are
eroding for about 100 feet. From this point downstream to the confluence with the North
Fork, and some length of the North Fork, the stream banks have localized erosion that
could be sloped and seeded according to landowner cooperation at the time of
construction.
The design approach at this site above the driveway culverts is to remove the coarse
sediment deposition and return the channel to its pre-storm alignment. This section of
channel will be constructed according to the Step-Pool Channel Detail included with this
package with a 4.5% slope and an average step spacing of 17 feet. A rock vane shall be
installed upstream of the proposed step pool channel to protect the right bank.
Downstream of the culverts, a series of rock vanes shall be installed in conjunction with
bank sloping to stabilize these sections of stream.
All disturbed banks shall be seeded and matted. Deep rooted woody vegetation will be
planted during the dormant season.

DSR 1- South Fork Big Pine Creek - Site 2
French Broad River Basin
2.46 square mile watershed
35.7783°N, 82.8075°11'
Scope of Work
This site is on South Fork Big Pine Creek off of South Fork Road, SR 1158 and is 0.6
miles upstream from its confluence with Big Pine Creek. This property belongs to
Thomas and Margaret M. Charles of Greenville, NC. The stream corridor is held in a
conservation easement by the NCWRC for I-26 mitigation. The 2005 floods caused
minor problems at 3 small areas along this corridor.
Area 1 is directly across South Fork Big Pine Road and just downstream from a drainage
culvert that carries a small spring under the road. This culvert plugged during the floods
and the resulting overland flow caused erosion of the stream bank along the road
shoulder, leaving a hole and sloughing bank of approximately 10 to 20 linear feet. Area 2
is just upstream of area 1 and consists of a reach where the channel has moved into the
left bank 5 feet. This has developed in part due to deflection of water velocity off of
large boulders installed at an upstream riffle section by NCDOT to repair flood damage
caused in the spring of 2004.This site was well vegetated with young trees; however,
their roots had not developed an extensive enough root mass to stabilize the bank. Many
of these small trees were undermined and have fallen into the stream. Area 3 is a 40 foot
section of the right bank where the channel is relatively stable; however, it is cutting into
the shoulder of the road. The only vegetation growing on this bank is grass because it is
on the edge of the road and is regularly mowed.
We propose repairing these 3 areas using boulder structures. Area 1 and Area 3 will both
be fixed by placing boulders into the right stream bank for toe protection. At Area 1 we
will stack boulders to provide some stability to the steep bank which is also the road
shoulder. The bank will then be sloped to match the adjoining areas, seeded and matted.
Area 3 will have a line of small boulders installed along the toe of the stream bank and
these will be pulled into the existing undercut bank to protect this reach of bank from
further erosion. Because this is in a pool area deflection of water velocity should be
minimal. We propose stabilizing the eroding meander at Area 2 by installing a vane at
the lower end of the bend and a second vane at the top of the bend. In between these two
vanes we will install a rootwad revetment to further stabilize this bank. Disturbed stream
banks will be seeded and matted with coir matting. Trees will be planted at the
appropriate time of year.

Area 1: repair will involve filling a hole in
the bank that resulted from a plugged
culvert and flow across the road and into
the main channel. We will stack boulders
in the eroded hole and back fill with soil.
The fill will be sloped to match the
existing bank, seeded and covered with
erosion control matting.
Area 2: The channel in this area is
meandering into the left bank
eroding the soil and undermining
the young trees growing there. We
propose to stabilize this bank by
installing two vanes, one at the top
of the bend and one at the bottom,
with rootwads placed between the
vanes. This should move the flow
toward the right bank and arrest
the movement of the channel into
the left bank.
Area 3: The bank at this site is relatively stable;
however, it is slowly under-cutting the road shoulder.
We propose placing boulder toe protection along the
channel edge to keep the channel from moving any
closer to the road.

Scope of Work
This site is on South Fork Big Pine Creek off of South Fork Road, SR 1158. It is 0.75
miles upstream from its confluence with Big Pine Creek. This property belongs to Jerry
Lunsford of Leicester, NC. The land on both sides of the creek is used as pasture. High
flows from the 2004 hurricanes caused severe bank erosion in several spots along this
reach. A lack of deep rooted woody vegetation and high banks on this reach contributed
to the bank failures.
The design approach on this site will be to slope, mat, and vegetate the banks in the areas
of severe erosion. Three J-hook vanes will be installed to protect the outside of meander
bends by shifting the thalweg to the center of the channel. Deep rooted woody vegetation
will be planted in the dormant season.

Scope of Work
This site is on South Fork Big Pine Creek off of South Fork Road, SR 1158. It is 1.8
miles upstream from its confluence with Big Pine Creek. This property belongs to Albin
Leuzinger of Inman, SC. Land use on the left side of the creek is hay field and the right
side is roadside at the upper section and grown up with brush and trees at the lower
section. In the upstream section of this reach, the left bank has failed due to storm
damage and is actively eroding, endangering two utility poles. Just downstream, the right
bank is eroded due to an extremely low radius meander. Downstream in the next
meander, there is 6 foot high left bank failure that is actively eroding.
The design approach at this site will be to adjust the stream alignment in the upper
section of the reach to move the stream back to its pre-storm alignment and to increase
the radius of curvature in the first meander. A cross vane shall also be installed in this
section of the reach to control grade and to keep flow in the center of the channel. A root
wad cluster shall be installed on the right bank of the first meander for reinforcement.
Downstream in the next meander, the left bank shall be sloped at 2:1 from bankfull and
two J-hooks and a root wad cluster shall also be installed for bank protection.
All disturbed areas shall be seeded and matted. Deep rooted woody vegetation shall be
planted in the dormant season.

Scope of Work
This site is on the South Fork of Big Pine Creek off of South Fork Road (SR 1158), 1.6 miles
upstream of the confluence with Big Pine Creek. The creek is on property belonging to Gary
Marler of Madison County. The land use on the left side of the creek is row crops while the right
side is road shoulder. The stream banks along this reach are severely eroded in places due to
high storm flows and a lack of flood prone area and deep rooted vegetation.
The design approach for greatest portion of this reach will be to bench, slope, and vegetate the
left bank above bankfull elevation to create a floodplain for the stream to access during storm
flows. Immediately downstream of the culvert the banks shall be sloped without a bench above
bankfull and lined with rip-rap for reinforcement. At the lower end of the site, the banks will be
sloped without a bench and boulder toe protection shall be installed on the right bank.
Immediately downstream of the field, 20 linear feet of boulder toe protection shall be installed on
the left bank in the vicinity of the utility pole. A small mid-channel bar in this vicinity shall be
removed.
All disturbed banks shall be seeded with temporary and permanent herbaceous seed mixes and
planted with deep rooted woody vegetation during the dormant season. All cut slopes shall be
matted with coir matting.

Erosion and Sediment Control Plan
Emergency Watershed Protection Program
Madison County
The following erosion and sediment control measures will be incorporated into all stream
repair sites.
1. The Contractor shall minimize vegetation disturbance by only working on the
stream bank and channel that is in need of repair. Existing buffers shall not be
disturbed unless directed by the designer.
2. The Contractor shall only enter the stream channel as shown on the plans or
directed by the designer. These stream accesses shall conform to the design
standards shown in the attached detail drawings. Timber mats may be used as a
substitute for rock per the approval of the designer.
3. The Contractor shall limit all bank and channel disturbance to activities that can
be completed by the end of each working day such that the work would remain in
place during an overnight storm event.
4. All equipment and uninstalled materials shall be removed from the channel at the
end of each working day and secured safely from potential out-of-bank flow
events that may occur prior to performing additional work.
5. Graded stream banks shall be stabilized with temporary and permanent seed and
coir fiber matting at the end of each working day. Seeding and coir fiber
matting specifications are included with this plan.
6. Stockpiles shall remain at least fifteen feet from flowing water and outside of the
top of bank. Silt fence shall be placed at the base of the stockpile between the
stockpile and the channel and must function to receive stockpile runoff before
entering the channel. Silt fence shall conform to design standards shown in the
detail drawings.
7. Temporary vegetation and permanent herbaceous vegetation shall be established
on all disturbed areas not already stabilized with matting, within five days after
construction is completed.
8. Permanent woody vegetations species are listed in the vegetation specifications;
planting details are also included.
Buck Engineering 1 of 8 River Works
TECHNICAL SPECIFICATION
Vegetation Planting
General Seeding
Seeding should be done immediately upon completion of final grading. Apply seed prior
to installing matting. Prepare the soil surface so that it is smooth and free from stones,
clods, or debris that will prevent the contact of the matting with the soil. Fertilizer and
lime are generally not necessary on most projects, particularly not on sites that have been
used for agriculture production or cattle grazing. Urban soils may require amendments.
Seed should be broadcast with a centrifugal seeder or by hand, at the full rate along
stream banks and in stockpile areas. In all areas where permanent seeding is used in
addition to the temporary seed, mixing of the seed for broadcasting is acceptable. Seed
and amendments (if needed) should be covered to a depth of 1/2 to 1 inch with soil by
using a hand rake, drag or other tillage equipment.
Seeding may also be done with a hydroseeder. Wood cellulose fiber will not be
acceptable as a substitute for straw mulch. A suitable tracer shall be used to clearly
identify areas hydroseeded. A minimum of 500 lbs. per acre of wood cellulose fiber or a
non-toxic water base dye may be used as a tracer. Seed shall not remain in water
containing fertilizer more than 45 minutes before being used. All products used to
hydroseed shall be non-toxic to aquatic organisms.
Temporary Seeding
For temporary seeding, apply the following vegetation at the listed rates and times.
Temporary Seeding (September to March):
Rye grain 3 lbs per 1,000 sq ft or 1301bs per acre
Temporary Seeding (April to August):
Foxtail Millet 1 lb per 1,000 sq ft or 40 lbs per acre
A combination of the two temporary seed types shall be used during the boundary months
of March, April, August and September to ensure survival. In all disturbed areas where
no permanent seed is being used (i.e. yard or agricultural field) and temporary seed is not
desired at the higher rate, broadcast temporary seed at the lower rate of approximately 1/2
the full lbs/acre stocking rate. When used in conjunction with permanent seed mix, apply
at !/2 the full lbs/acre rate.
Permanent Seeding
Permanent seeding will be accomplished using the mix listed below:

Trees shall be planted as either bare rooted or containerized material. Trees should be
planted at a rate of 400 stems/acre (roughly 10 feet on center) where EWP repairs have
been accomplished. Planting of this material will be done during the dormant season
(late fall and winter of 2005-2006). Refer to the attached details and specifications for
more information.
Stream banks
Live Staking
Species used for live staking shall be taken from the following species:
Scientific name Common name
Cornus antomum Silky Dogwood
Salix sericea Silky Willow
Santbucus canadensis Elderberry
Cephalanthus occidentalis Buttonbush
Salix nigra Black Willow
Stake at 2-3 foot spacing on the outside of all meander bends. Stake at 6-7 foot spacing
on the inside of meander bends and all tangent sections. Note this is appropriate for most
rural systems. Urban or flashy systems should be staked at higher rates. Utilize as
diverse a species group as feasible and make sure that black willow constitutes less than
25% of total stakes used.
Containerized Plants:
Containerized shrub material may also be used on the stream banks to increase the
diversity. Applications and spacing should reflect that of live stake material.
Mulching
Mulching shall be used to provide temporary protection of soil surfaces from erosion.
Mulching should be performed within 48 hours of seeding. Grain straw mulch should be
applied on seeded areas at a rate of 75 bales per acre. Apply mulch uniformly.
Buck Engineering 4 of 8 River Works
Erosion Control Matting
Ecostakes
Provide wooden stake not less than 12 in. (300 mm) in length with a notch cut 1 in. (25
mm) from the top. These stakes shall be used to stake the matting along the slopes.
Wooden 3 ft. stakes spaced approximately 4 ft. apart shall be used to secure the matting
at the toe of slope. The toe stakes shall have a minimum 1-inch by 1-inch cross-section
and shall be designed so that the matting can not slide past the exposed end of the stake.
Refer to the attached details and specifications for EWP work for more information.
Coir Fiber Matting
The erosion control matting shall be a machine-produced mat of 100% coconut fiber with
the following properties:
Matrix 100% Coconut Fiber
Weight 20 oz/SY (678 gm/m2)

6.6 x 164 ft (120 SY) or (100 SM)
"C" Factor 0.002
Place the coir fiber matting immediately upon final grading. Provide a smooth soil
surface free from stones, clods, or debris that will prevent the contact of the matting with
the soil. Apply seed prior to installing matting. Begin at the bottom of the slope by
anchoring the matting in a 6-inch (15 cm) deep by 6-inch (15 cm) wide trench. Backfill
and compact the trench after staking. Walking backward down the stream, allow the
matting to unroll slowly; ideally the matting roll will rest against your shin as you walk.
Stake the matting according to recommended stake pattern for specific product and slope.
(See stake pattern guide that comes with the product.) Place matting in full contact with
the soil.
The edges of the parallel matting must be staked with approximately 2 inches (5 cm) of
overlap such that the edge of the downstream matting is under the one just upstream.
When matting must be spliced down the slope, place matting end over end (shingle style)
with approximately 6 inches overlap. Drive stakes through the overlapped area.
Place stakes across the matting at ends, junctions and trenches approximately 1.3 ft apart.
Place stakes along the outer edges, down the center of each strip of matting and along all
lapped edges approximately 2 ft apart. Cut excess matting and anchor at the end of the
slope.
Buck Engineering 5 of 8 River Works
Temporary Stream Access Ramps
Stream access ramps shall be constructed using either rock or timber mats in locations as
shown on the plans or as directed. Grading shall be performed only to the extent needed
to form a stable ramp connecting the stream bank grade to the streambed. The Contractor
shall determine the appropriate number of timber mats and ramp angle according to the
equipment that will be using the ramp. Stream access ramps are temporary and shall be
removed and the areas restored to their original state when they are no longer needed or
permanent measures are installed.
Sediment Fence
Geotextile sediment fences shall be used to trap sediment from areas of limited runoff.
Sediment fences shall be properly anchored to prevent erosion under them. These works
are temporary and shall be removed and the areas restored to their original state when
they are no longer needed or permanent measures are installed. Locations for sediment
filters are shown on the plans. Refer to sediment fence specifications (6.62) in the NC
Erosion and Sediment Control Planning and Design Manual for material and installation
requirements.
Gravel Construction Entrance/Exit
Temporary gravel construction entrances shall be constructed as shown on the plans and
according to specification 6.06 of the NC Erosion and Sediment Control Planning and
Design Manual.
In-stream Structures
In-stream structures include w-weirs, cross vanes, j-hook vanes, log vanes, and wing
deflectors. The quantity of in-stream structures to be constructed shall follow approved
plans, but may be affected by conditions encountered during construction
Boulders used for in-stream structures shall be relatively flat on either side in the same
dimension, preferably the long dimension, and must have relatively smooth ends. No
more than 5% of the boulders shall be smaller than 3'x2'x2'. Boulders larger than
6'x4'x3' shall be permitted. Boulders found on-site and approved for use by the
Developer will be used to the extent feasible.
The Contractor shall construct in-stream structures with equipment capable of moving
and accurately placing boulders of approximate dimensions 6'x4'x3'. If suitable for
backfill, excavated material shall be placed on the upstream side of structures or as
directed. Unless otherwise approved by the Developer, excavation to prepare the
subgrade for the installation of in-stream structures shall be consecutive and continuous.
Once the excavation of a structure has begun, the structure shall be completed by the end
of the workday. All equipment shall be removed from the stream at the end of each
workday. Any accumulation of sediment in the channel shall be cleaned as needed
during construction and at the end of construction. No separate payment will be made for
this clean-up work.
Buck Engineering 6 of 8 River Works
Construction Sequence of Events
Construction shall be performed at the EWP site in accordance with the plans and in
general accordance with the following sequence:
1. Mobilize equipment and materials to the site.
2. Set up construction access pads, staging areas, haul roads, and silt fences.
3. Install stream access ramps.
4. Excavate and grade banks and construct in-stream structures.
5. Seed and mat graded banks and immediately upon reaching final grades.
6. Stabilize all disturbed soil with temporary and permanent seed prior to leaving the
site each day and prior to moving to the next work area.
7. Dispose of excess materials at approved off-site locations.
8. Remove stream access ramps.
9. Remove silt fence and seed and mulch staging areas to restore these areas to pre-
project conditions.
10. Demobilize grading equipment from the site. Remove construction access pads.
11. Plant bank, floodplain and buffer woody vegetation and live stakes during the
dormant season.

NOTES
TRENCHING METHOD:
IF THE ROOT WAD CANNOT BE DRIVEN INTO THE BANK OR THE BANK
NEEDS TO BE RECONSTRUCTED, THE TRENCHING METHOD SHOULD
BE USED. THIS METHOD REQUIRES THAT A TRENCH BE EXCAVATED
FOR THE LOG PORTION OF THE ROOT WAD. IN THIS CASE, A FOOTER
LOG SHOULD BE INSTALLED UNDERNEATH THE ROOT WAD IN A TRENCH
EXCAVATED PARALLEL TO THE BANK AND WELL BELOW THE STREAMBED.
ONE-THIRD OF THE ROOT WAD SHOULD REMAIN BELOW NORMAL BASE
FLOW CONDITIONS.
NOTES
DRIVE POINT METHOD:
SHARPEN THE END OF THE LOG WITH A CHAINSAW BEFORE "DRIVING"
IT INTO THE BANK ORIENT ROOT WADS UPSTREAM SO THAT THE STREAM
FLOW MEETS THE ROOT WAD AT A 80-DEGREE ANGLE, DEFLECTING THE
WATER AWAY FROM THE BANK A TRANSPLANT OR BOULDER SHOULD BE
PLACED ON THE DOWNSTREAM SIDE OF THE ROOT WAD IF A BACK EDDY
