Approval of 401 Water Quality Certification with Additional Conditions
Dear Mr. Horton:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 325 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 June 27, 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 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.

Amount
Approved Units Plan Location or Reference
Stream 325 feet West Fork Pigeon River
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.
Haywood County:
Page 3 of 6
June 28, 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 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.
Haywood County:

June 28, 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
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
Haywood County:
Page 5 of 6
June 28, 2005
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 maybe 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.)
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.ITurbidity 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.

R.E.: 404/401 Permit Applications for Haywood EWP Work
Dear Mr. McLendon and Ms. Karoly.
x
Attached please find the subject applications for five EWP sites in Haywood County. The information included
with these applications has been developed in conjunction with the Natural Resources Conservation Service, the
Haywood County Soil and Water Conservation District, the Army Corps of Engineers, Asheville Office, DWQ's
Asheville Regional Office, the NC Wildlife Resources Commission and the US Fish and Wildlife Services. The
technical details and supporting information was developed and compiled by our consultant team, which is
coordinated by McGill Associates, P.A. This is Haywood County's submission for critical EWP sites on the West
Fork of the Pigeon River, the East Fork of the Pigeon River and the Pigeon River just below the confluence of the
East and West Forks. We have directed our representatives to carefully develop these applications and to provide
adequate opportunity to consider all potential impacts of this work and to proceed with this urgent stream repair
work. We look forward to quick regulatory action and approval of these repair plans so this important public good
work can be accomplished.
As we enter again into the hurricane season for the east coast of the United States, Haywood County and all those
areas affected by the devastating hurricanes and tropical storms from 2004, we are reminded that getting these
damaged stream areas repaired is an essential objective in trying to minimize future environmental and property
damage impacts from these still damaged sites.
We have made every effort to effectively address each and every concern related to this repair work and the need to
protect this area's water resources. The County, in an effort to meet all threatened and endangered species issues
associated with this work completed a resource survey of our repair/debris sites within the areas designated as
"Critical Habitat" for the Appalachian elktoe mussel (Alasmidonla raveneliana) (AE). This report was used
extensively to help fashion a repair plan, erosion control measures and a construction sequence for this work that
will have no significant impact on any AE or the water quality of the streams affected. In addition, on June 2, 2005
we held a day-long meeting with the regulatory and resource agency representatives to review these plans and to
visit the sites within the Critical Habitat areas. I was pleased that Mr. McLendon was able to attend that meeting.

We have carefully incorporated all the comments received during that consultation with the agencies and believe we
have captured the issues noted in reviewing this essential stream repair work. Please note we have included within
_the .construction sequence,-asuussel survey_and,if needed, relocation effort prior to commencing construction__This. _
was specifically suggested by the USFWS and NC WRC representatives at the June 2ond site review meeting. We
have provided significant other measures to limit any impact that this work may have on habitat or any organisms in
the stream areas affected by this work. This mussel protocol is provided with the understanding that it would be
done only if USFWS requires this process as part of their "consultation" to meet Section 7 of the Threatened and
Endangered Species Act.
Frankly, we believe that the ongoing water quality impacts of these damaged and exposed stream bank areas
represent a great threat to downstream waters and the habitat associated with the identified endangered AE, not to
mention the hazard they represent to property near the sites. We believe that the repair plans developed for these
sites are comprehensive and represent well thought-through consideration of the existing water quality problems and
will result in effective management of any "short term" impacts during the construction phase, even without the AE
survey/relocation protocol.
We are looking forward to being able to proceed with this work. Please let me or our coordinator for this project,
Mr. Ken Futreal (828.400.3279) know of any issues or consideration that we need to make to secure approval for
this planned work. In accordance with the contact we have made with DWQ's regional 401 contact, Mr. Keven
Barnett, we have submitted directly to him his copy of these repair plans and applications. In addition, since the
State of North Carolina has "waived" fees for these EWP 401s, we have not included any permit fees. Thank you
for your attention to these applications.

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:
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.
The streambank on the east side needs to be repaired and restored to avoid continued
sedimentation and future destruction of property. Restoring the channel to the pre-storm
conditions and stabilizing the streambanks will provide the appropriate protection against
future high water storm events. Access for this repair work is along an existing maintained
drive which is adiacent to the river. When at all possible, equipment will be kept out of the
stream channel, stream crossings will be minimized. When at all possible, backfill material
will be moved from dry areas to banks, minimizing the movement of wet (stream)
material.Temporary and permanent herbaceous vegetation shall be planted on all bare
soils within 15 days of ground disturbing activities.

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.nc.us/ncwetlands/stnngide.htm].
1. 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

Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
1. PROJECT PURPOSE & DESCRIPTION
The purpose of this project is to stabilize and/or repair eroded and unstable stream banks
along the West Fork of the Pigeon River (below the confluence of the East and West
Forks) that were impacted by flood flows from Hurricanes Frances and Ivan in
September of 2004. The severely eroded stream banks consist of exposed soil on
moderate to steep slopes and extensive woody debris, which, if transported during
another high flow event, could block downstream culverts and bridges as well as cause
increased erosion and sedimentation in vulnerable High Quality waters. As desired by
the landowner(s) and charged to us by Haywood County, NC, the proposed design is
intended to reconstruct the damaged bank(s) as "close as possible" to the original pre-
disturbance conditions. This site, is located within a designated Critical Habitat for the
Appalachian elktoe mussel (Alasmidonta raveneliana) (AE) zone. Accordingly it is
important that the appropriate construction methods (including erosion and sediment
control practices) be utilized during the repair construction to protect local and
downstream habitat. The continued sedimentation occurring from this damaged site is an
ongoing impact to the downstream waters and its careful, quick repair is critical to
protecting stream resources.
The work described in this Stream Repair and Bank Stabilization Plan (Repair Plan) is
urgent and compelling work under the National Resource Conservation Service (NRCS)
Emergency Watershed Protection (EWP) program to protect existing property and
structures. NRCS is the funding agency and Haywood County / Haywood Soil and
Water Conservation District (SWCD) is the sponsor and responsible party for the project.
Work on the site consists of repair and stabilization effort only, and is not considered
natural channel restoration or enhancement work. However, some methods and
approaches utilized in the proposed repairs are routinely applied in natural channel design
efforts due to their ability to protect channel banks from shear stresses and the resultant
erosion.
All work in or near surface waters will be fully supervised by trained personnel from both
i McGill Associates and Soil & Environmental Consultants (S&EC). This site is just one
of seventeen (17) similarly damaged sites selected for repair within Haywood County as
part of Haywood County bid invitations HC-102, HC-103, and HC-104. Each of the sites
is considered independent of one another (non-contiguous) due to the physical separation
typically in excess of several thousand feet between sites.
2. SITE DESCRIPTION
Site #5 - Campground Site - Pigeon River (WS-III,Tr Waters) (below confluence of East
and West Forks) - The repair site is approximately 325 feet in length and is located along
the Pigeon River in Haywood County, NC. This area is located immediately west of the
intersection of NC 110 and Lake Road (just north of the NC 110 bridge crossing over the
East Fork of the Pigeon River). Please refer to repair plans for photographs, mapping,
imagery, and details of existing site conditions.

Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
Approximately 325 feet of the right channel bank (left and right are referenced looking
' downstream) was severely damaged through bank erosion and soil loss. The property is
currently owned by Mr. Steven Eaffaldano and wife (Barbara).
Banks along this portion of the repair reach range in height from roughly 10 to 12 feet
and are near vertical in some locations. We understand that numerous large diameter
trees along the repair reach have been lost as a result of undermining and subsequent
bank failure. Based on a review of available mapping and imagery, the width of bank
loss varies from 15 feet to as much as 30 feet along the repair reach. No repairs have
been performed along this portion of the repair reach. Little to no available repair
materials exists along the repair area. There is little or no soil material available on the
bank to provide for a planting media.

Access to the site is not an issue as the site entrance is located on NC 110. Where visible,
site utilities were located as described on the site repair plan. Utilities must be located
and marked by contractor prior to construction. The disturbed area for the proposed
repair and stabilization is 0.50 Acres, and is exempt from an Erosion Control Permit from
Land Quality. The Campground Site work described in this plan will need to be permitted
by the U.S. Army Corps of Engineers (Section 404 permit) and the NC Department of
Environment and Natural Resources, Division of Water Quality (Section 401 Water
Quality Certification).
3. TECHNICAL REPAIR DESCRIPTION
On April 1, April 13, and again on May 19, 2005 members of our design team visited the
repair site to gain an understanding of current site conditions and perform a general site
characterization. While on site, we observed characteristics of the site and surrounding
area, verified surface and channel flow conditions, and observed existing property
boundaries, select utilities, site accessibility, and existing water conveyance structures.
During this process, we observed exposed eroded banks along the repair reach (which
were caused by the hurricanes) to typify failed bank height, slope, materials, vegetation,
and general site conditions.
While on site we also observed existing channel banks immediately upstream and
downstream of the repair area as well the existing channel banks on the opposite side of
,the watercourse (in most cases only one bank of the existing channel was damaged).
Utilizing GPS and laser-level (or Total Station) equipment, we collected select site data
to locate the extent of the damage and characterize the existing conditions along the
repair reach. We field measured one or more bank cross-sections while on site. The
cross-section(s) location were selected to typify the existing bank condition along the
repair reach. A plan sketch of the existing site conditions along typical cross-section(s)
taken along the repair reach is shown in the Repair Plans.
We discussed the site conditions (including a description of pre-damage site) with the
landowner landowners (Mr. Steven Eaffaldano and wife Barbara). We photographed the
project sites and prepared field notes for use in the preparation of our design.

After completing our field visits, we performed a preliminary review and evaluation of
available site mapping to include USGS 7.5 Minute Quad data, Digital Orthophoto Quad
(DOQ) data (1998), Color Infrared imagery (2004), Haywood County Soils Survey map
sheets, as well as other available map data. Using Arc-GIS (with available extensions)
and Digital Elevation Models (DEM) from the NC Floodplain Mapping Project we
estimated the contributing drainage area (at the project site) at approximately 118.4
square miles. We also researched available hydrologic and hydraulic data for the project
site, including a review and evaluation of available Regional Curve data (NCSU - Stream
Restoration Institute (SRI), Preliminary Mountain Curve) for incorporation into the repair
design process as applicable.
Using the data collected during our field visits, we developed a rough site sketch defining
existing conditions with annotated hand notes, descriptions, and repair recommendations.
These notes were later refined for use in the development of our repair "concept" for the
site roughly defining the locations, sizes, and types of modifications and features
proposed for construction at the site. This "concept" was later discussed on site with
representatives of Haywood County, reviewing Agencies (typically including USACE,
NCDENR-DWQ, NCWRC, U.S. Fish & Wildlife, and NRCS.) and the landowners to
solicit input and gain concurrence of our design approach. Since our site meetings we
have incorporated Agency concerns and comments into our plan. Due to the sensitivity
of the designated AE Critical Habitat within Haywood County we have paid special
attention to this topic in an attempt to provide short and long term protective measures for
this Federally Endangered Species. These measures are addressed in detail later in this
report.
In addition to the Existing Site Plan, we also developed our Proposed Repair Plan
including plan view, typical repaired bank cross-sections, construction details for typical
site features, technical construction specifications, and planting recommendations for the
recommended repairs.
4. DESIGN CONSIDERATIONS
As described in our technical proposal, we considered a range of possible repair
alternatives for the Campground Site. These repair alternatives included: 1) Repair-in-
Place Only, 2) Repair-in-Place augmented with In-Stream Structures, 3) Stream
Restoration - "Natural Channel Design."
As our understanding of this and other repair sites has increased, and in an effort to
streamline the approach to repairs we further developed these repair alternatives. In our
design development we strived to utilize techniques which would be simple and
understandable to a "typical" general contractor (reducing the need for specialty
contractors) and which could be easily modified or refined in the field by the designer (or
" contractor) based on site conditions encountered during construction. It was also our
intent that repair and stabilization methods would be constructed with commonly used
and readily available construction materials.
4
Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
Recommended repairs have been designed with robust methods to withstand typical
channel discharges and erosive channel forces. One commonly observed approach to
such bank repairs includes a complete lining of repaired banks with large boulders or
riprap. It is our opinion that such an approach would be undesirable for three main
reasons. 1.) These repairs do not take into account the primary reason for the damage in
the first place, that of excessive shear stresses on the bank and tend to serve as a "band-
aid" approach to bank repairs. 2.) Such repairs utilize excessive volumes of rock
resulting in considerably high repair costs. 3.) The placement of large volumes of rock
for continuous lengths in effect "armors" the banks and fails to provide the desired
(reconstructed) habitat that previously occurred naturally within the system (boulder,
cobble, gravel substrate materials) bed and banks. Such habitat is key to a variety of
aquatic species (including the AE mussel).
Our selected repair alternative for the site includes repairing the failed bank back to its
pre-disturbance location (through fill placement) and augmenting the repair with in-
stream structures. The proposed repair plan calls for the utilization of off-site borrow
materials including river bed borrow consisting of sand, gravel, cobble, and small
boulders for the reconstruction of the lower bank zone. Elevations above the lower bank
zone will be constructed utilizing varying fill materials including both river bed borrow
and other suitable borrow sources.
Based on the observed (and measured) condition of the failed bank and the amount of
disturbance that has occurred, the bank repair alone (without supplemental in-stream
structure reinforcement) would likely be insufficient to withstand future flood flows. The
installation of in-stream rock (boulder) structures will reduce near bank stresses along the
repair reach to protect the rebuilt banks. Additionally our repair also calls for the
'installation of toe stabilization as necessary along the reach in areas of excessive scour to
tie-in to existing stabile banks. The designer may also designate other areas requiring toe
stabilization at the time of construction.

This approach to bank repairs will improve the overall potential for the success of the
repair. The installation of structures will protect channel banks with a significantly
smaller rock volume (when compared to bank lining) thereby reducing overall repair
:costs. One additional benefit to this type of repair is the replacement of a natural (less
structural) repair that is more appropriate for the reach and generally more aesthetically
desirable.
5. PROPOSED REPAIR PLAN
During our evaluation of the site, infrared imagery (2004) was used to estimate the pre-
'disturbance location of the "channel bank." This location was then used to develop a
repaired bank location as shown in our Repair Plan. Typical cross-section(s) for the
repair were then developed to depict proposed repair characteristics including but not
limited to slopes and slope breaks, stabilization methods, and planting recommendations.

Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
NOTES:
1. Our repair plan is designed to repair and stabilize the banks along the subject
reach and is not considered natural channel restoration or enhancement work.
And, while consideration was given to select characteristics of the channel it
should be recognized that a complete morphological evaluation of the repair
reach was not performed nor does this report (or repair) represent such an
evaluation. However, some methods and approaches utilized in the proposed
repairs are routinely applied in natural channel design efforts due to their ability
to protect channel banks from shear stresses and the resultant erosion.
2. It should be noted that this "channel bank" location and the resultant "channel
width" is not to be considered the bankfull channel edge or bankfull width (as is
routinely described in Natural Channel Design Methodology), nor should it be
considered the "edge of water" as this location will differ for various reasons. It
is however, a rough interpretation (estimate) of the pre-existing channel bank
location based on the best available pre-damage site and mapping data,
discussions with landowners, observation of undisturbed channel segments
immediately upstream and/or downstream of the site, and experience on similar
projects.
3. Due to previous alterations of the channel including but not limited to bridge
construction, bank grading, the construction of flood levees, and in-channel
quarry operations, channel banks, widths, and slopes have been modified
considerably. In turn, the identification of the "natural" condition (dimension,
pattern, and profile) of the channel is often difficult or indeterminate.
For comparison purposes we attempted to confirm our "channel bank" location by
comparing the resultant "channel width" to available Regional Curve data. Based on a
review of site data (upstream and/or downstream) and our estimated "channel bank"
we estimated the pre-disturbance "channel width" at approximately 110 feet.
location
,
We compared this "channel width" to estimated bankfull width as determined from
available (preliminary) mountain Regional Curve data (SRI) for the appropriate drainage
area. The regional curve indicates a bankfull width of approximately 114 feet based on a
drainage area of 118.4 square miles. Based on this comparison it is our opinion that the
estimated pre-disturbance "channel location" is appropriate.
As shown on the attached repair plans and design details, we recommend that the
repaired slope be reconstructed and backfilled with excavated channel material (or
deposited material recovered from the floodplain), available on-site or off-site earth fill,
and in some cases imported stone aggregate. The location of the toe of the repaired slope
will be field determined to allow for the development of a typical repair application along
the reach. Our Repair Plan calls for the incorporation of a single repair option, Option 1.
See the proposed repair cross-sections depicted in the Repair Plan.

d Site -Stream Repairs & Bank Stabilization Plan June 8, 2005
Campground Haywood County Invitation # HC-103 McGill Associates, P.A.
Repair Option 1
For Repair Option 1, our design has divided the repaired bank into three bank
zones, Upper, Mid-, and Lower for the purposes of slope, stabilization measures,
and planting recommendations. A bench (small floodplain) will be constructed
between the Lower and Mid-Bank Zones.
Gradiniz & Stabilization
We recommend that the Lower Bank Zone be graded (or constructed) with the
previously described materials at a slope of not in excess of 2H:1 V to the
approximate elevations described in the repair cross-section. As this zone is
within the "active channel" we recommend that it be lined with CF-7 (coir fiber)
erosion control matting (or equivalent), planted with live stake (cuttings) of the
species and density described in the planting details. This zone should be over
seeded with the appropriate temporary and permanent grasses for the season.
Repair Option 1 will include the construction (or grading) of a bench (or small
floodplain) extending landward from the elevation break-point between the Lower
and Mid-Bank Zones (Proposed Slope Break). The width of this bench will
depend on the available area (based on landowner desires and site constraints) and
the necessary cut volume. However, a minimum bench width of 5 to 10 feet is
desired. The back of this bench should then be graded and tied to the existing top
of bank (floodplain or terrace) elevation at a slope not greater than 311: IV as
described below as the Mid-Bank Zone. The upstream and downstream ends of
the bench will be graded to blend smoothly with the existing undisturbed banks.
The Mid-Bank Zone should be similarly graded (or constructed) with the
previously described materials at a slope of not in excess of 3H:1V to the
approximate elevations described in the repair cross-section. As this zone is out
of the "active channel" we recommend that it be lined with excelsior (wood fiber)
erosion control matting (or equivalent), planted with select shrubs (bare root or
containerized specimen) of the species and density described in the planting
details. This zone should also be similarly over seeded with erosion control
grasses. Where possible, transplanting of woody vegetation from on-site
including root mats will be performed to assist in the stabilization of banks within
the bench, Lower, and Mid-Bank Zones.

typical and should be verified and adjusted as necessary along the length
of the repair reach.
3. The Proposed Slope Break depicted on the Repair Plan defines the
approximate location of the break between the Lower Bank Zone and the
streamside edge of bench (or Mid-Bank Zone as described later for Repair
Option 2).
The Upper Bank Zone should be graded (or constructed) with the previously
described materials such that it blends the Mid-Bank Zone with the surrounding
floodplain grade to the approximate elevations described in the repair cross-
section. As this zone is out of the "active channel" we recommend that it be lined
with excelsior (wood fiber) erosion control matting (or equivalent), planted with
select tree (bare root or containerized specimen) of the species and density
described in the planting details. This zone should also be similarly over seeded
with erosion control grasses.
In-channel Structures
As previously described we recommend that the repaired channel bank be
augmented with in-channel structures including rock (boulder) vane arms. These
structures will be utilized to reinforce and stabilize the proposed bank repairs. All
structures will be constructed out of natural materials typically consisting of
locally quarried boulders. The upstream side of these structures will be lined with
a non-woven fabric and backfilled with excavated channel material and in some
cases imported stone (off-site river bed borrow materials or other available coarse
aggregate if approved by the engineer) to improve stability and reduce the
potential for piping.
These in-stream structures concentrate stream energy toward the center of the
channel and away from the near-bank areas. In doing so, the structure reduces
shear stress along the banks and prevents bank erosion. (In this case, such
structures allow for an additional measure of protection of the repaired bank until
vegetation can take hold). This approach would also likely reduce the overall
volume of stream stabilization material that must be hauled to the site and reduce
costs for the overall repair.
The attached Repair Plan generally describes the number and type of in-channel
structures to be installed. The designer will determine the exact spacing, length,
and location of the in-channel structures at the time of construction. For planning
purposes, we estimate that a minimum of two (2) rock (boulder) vane arm
structures will be installed along the repair reach. A detail of a rock vane arm
structure is shown in the Construction Drawings.

Toe Stabilization Measures
Depending on conditions encountered during construction, occasions may arise
where supplemental stabilization of the bank toe is necessary. Where such
conditions are encountered, banks would be reconstructed using rows of large
boulders along the newly defined toe of the repaired bank. Footer rocks
(boulders) and toe rocks (boulders) will be installed as shown in the details. In
these cases, the landward side of these structures will be lined with a non-woven
¦ geotextile fabric and backfilled with suitable material (off-site river bed borrow
materials or other available coarse aggregate if approved by the designer). This
material combination in conjunction with a more suitable slope (likely not in
excess of 2H:1V) will improve stability and reduce the potential for future scour
and piping (and resulting failure).

reconstruction would be difficult), near existing large diameter trees (
experienced undercutting) which are to be maintained, and at the upstream and
downstream repair limits (where tie-in to undisturbed banks is needed). For
planning purposes we have estimated that 40 to 50 percent of the repair reach will
require toe stabilization measures. A detail of a typical toe stabilization structure
is shown in the Construction Drawings.
? Bank Plantings
A riparian buffer area will be established along the repaired channel bank as part
of the proposed Repair Plan. The riparian zone will include all three Bank Zones
(Lower, Mid-, and Upper) and any constructed bench. These areas will be seeded
and planted with the appropriate native riparian vegetation and will provide
channel stability and treatment of surface waters traveling laterally through the
buffer.
Species will consist primarily of native trees and shrubs. The repaired bank will
be planted with the appropriate channel bank species in the form of live stakes,
bare-root seedlings (and containerized plants), and transplants where available.
Native trees and shrubs that are available elsewhere on site will be removed with
as much of the root ball intact and transplanted adjacent to the restored channel or
in the floodplain. The majority of the planting efforts with the exception of site
transplants) should be delayed until the fall season to increase survivability.
Vegetation will be supplied by locally identified plant sources or purchased from
local, reputable nurseries. Other sources, outside of the local area, may be used
depending on the availability of plant material and as approved by the designer.
Tree species individuals will be planted randomly at an 8 ft. by 8 ft. spacing in
order to ensure a desired planting density of 680 stems per acre. This will

species listed in the planting schedule. Plants shall be installed as shown in the
planting details. Tree protection shelters shall be installed on all planted bare-root
seedlings.
Shrub species will be planted at a higher density and closer spacing (6 ft. by 6 ft.) to
achieve a desired planting density of approximately 1,200 shrubs per acre here

will include a minimum of three of the seven shrubs listed in the planting schedule.

6. APPALACHIAN ELKTOE MUSSEL CONSIDERATIONS
As identified and described by the US Fish and Wildlife Service , population of the
federally endangered Appalachian elktoe mussel (Alasmidonta raveneliana) (AE) is
known to exist in the Pigeon River subbasin in Haywood County, NC. Critical Habitat
has been designated for this species along a significant length of the West Fork Pigeon
River and the main stem of the Pigeon River (below the confluence and above Canton).
In light of this matter, the USDA Natural Resources Conservation Service (NRCS)
previously engaged The Catena Group (TCG), a team of freshwater mussel experts from
Hillsborough, NC, to survey a series of reaches along these waters for which stream
repairs and bank stabilization efforts are proposed. Subsequent to their on-site visits,
TCG prepared a report (Freshwater Mussel Survey Report for the NRCS Restoration
Efforts on the Pigeon River, TCG, April 19, 2005) describing the surveyed species,
habitat characteristics, species threats, and the methodologies and results of their field
t
surveys.
10

Campground Site- Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
As previously described, of major concern to NCRS (as well as landowners) is the
continued bank erosion occurring along this repair reach and other sites (identified and
yet unidentified) within Haywood County. Without repair, the likelihood of continued
bank erosion and resultant local (and downstream) deposition is high. This erosion will
continue to affect the quality of system waters in addition to downstream aquatic and
riparian habitat well beyond what has already occurred. The TCG report also describes
known threats to the AE species and their contribution to the decline in the population.
These threats include sedimentation, point and non-point source pollution, and habitat
modification (impoundments, channelization, etc.). The report describes sedimentation
(siltation) as a "major contributing factor to the degradation of mussel populations."
The purpose of these surveys was to identify mussel populations (or individuals) within
the subject repair reaches and provide recommendations regarding future repair efforts
within these waters. As described in the report, surveys extended from a point
approximately 100 meters upstream of the repair area to a point approximately 400
meters downstream of the repair area. According to the report, surveys were conducted
through these lengths in areas of the "best" potential AE habitat (based on the surveyors
understanding of the desired habitat). Additionally the report also notes "....Some areas
within these parameters were determined not to contain potential mussel habitat due to
their level of degradation...."
Of the seventeen stream repair and bank stabilization sites in Haywood County, only five
(5) are located in designated Critical Habitat. On only four (4) of these sites were
individual Appalachian elktoe mussel specimen were found. A total of five (5) individual
mussels were found with the greatest number found at a single repair site being two (2).
We understand that individual mussels were collected, identified, counted, and returned
to the substrate. For details on survey personnel, operations, methodology, and results,
the interested reader is referred to the report.
Described in the report prepared by TCG are recommendations for construction
operations and general measures to be considered for all repair sites. These measures
include:
1. Install and maintain erosion control devices throughout the project site and take
all other appropriate measures to avoid excessive turbidity and sedimentation.
2. Only conduct in-stream activities during periods of low flow. Cease construction
during high water or rain events.
3. Construction activities to be conducted in the least amount of time practicable.
4. Construction staging sites should be located outside of flood prone areas.
5. Immediately (as soon as possible) re-vegetate construction/access areas with
appropriate native flora after restoration efforts are completed.
11
Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
6. Cut large downed trees into smaller, more manageable sections prior to removal
from site.
7. Minimize the cutting of living native vegetation from sites to include only
individual trees that are in imminent danger of falling into the river and avoid
heavy machinery contact with existing vegetation.

We have incorporated the recommendations provided by TCG into our Stream Repair
and Stabilization Plan details and construction sequence. We have also included the
input and comments received from Mr. Mark Cantrell and Mr. John Fridell of the U.S.
Fish & Wildlife Service (USFWS) and Mr. Steve Fraley and Mr. Dave McHenry of the
NC WRC during our June 2, 2005, office meeting and subsequent site visit to this and
three other sites within the Pigeon River subbasin. Specifically, we have included the
following additional measures to reduce potential short term (during construction) and
long term detriment to AE Critical Habitat areas:
1. We have identified a single ingress/egress point along the repair reach. This
location, typically at the "low bank" location, was selected to reduce the overall
length and width of disturbance to the remaining stable bank, while restricting
equipment traffic to a single location thereby reducing the potential for additional
bank collapse and erosion and subsequent local and downstream sedimentation.
A detail for this ingress/egress access location is included in the plans. It is
intentionally similar to commonly applied temporary stream, crossing methods
utilized during stream restoration projects.
NOTE: We considered the possibility of access to the repair areas from
adjacent parcels on the opposite side of the channel. However, based on
accessibility (and ownership issues), dense streamside vegetation along
the opposite bank (and our desire not to disturb it), and USFWS
recommendations to reduce the overall traffic area to a minimum, we
recommend that access occur from the near (repair) side of the channel.
2. We have called for the incorporation of temporary silt fence and temporary
diversion or interceptor swales (when possible based on topography) to reduce
the potential for overland flow (often sediment-laden) to be discharged over the
bank during or after construction. Such devices, while simple, will also reduce
the potential for concentrated flow to occur over the repaired banks until such
time as they are stabilized with ground cover (erosion control seeding measures).

t
3. We have identified in-channel "limits of disturbance" to be applied during
construction. It is our intent that this limit, extending not more than one-third of
the original width of the channel along the repair reach, will identify the sole
zone of operation for excavation (associated with in-stream structures and toe
stabilization measures), fill placement (for bank reconstruction), and equipment
traffic. The designer will define these "limits" prior to construction utilizing
flagging, driven steel stakes, buoys, or other methods such that the area and
12
1
Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
limits can be readily identified during construction. This measure alone will
significantly reduce the potential for habitat damage and mortality of AE
individuals or a local population. Additionally the restricted traffic area will
reduce the disturbed bed area and reduce the potential for bed disturbance and
r downstream deposition of disturbed materials.
4. For sites within the Critical Habitat areas, we have included in our proposed
Construction Sequence a series of up to three (3) pre-construction localized
mussel survey and relocation sweeps throughout the "limits of disturbance"
described above. Provided that USFWS requires these actions as part of the
approval process for this work, these mussel survey efforts and relocation efforts
will be included as part of the construction sequence for these repairs. The first
sweep will occur not less than three (3) weeks prior to the commencement of
construction operations within .the marked area. During this sweep (Sweep 1)
any individual AE mussel specimen will be collected in preparation for
relocation. A second sweep (Sweep 2) of the marked area will be performed
within approximately one week of the completion of Sweep 1. If any AE
mussels are collected they too will be prepared for relocation and a third and final
sweep (Sweep 3) will be scheduled. Sweep 3 will be performed within the
remaining last week prior to construction. Any individual AE mussels identified
will be similarly collected and prepared for relocation. If no AE mussels are
collected during Sweep 2 then Sweep 3 will not be necessary, however, at a
minimum two sweeps (Sweeps 1 and 2) will be performed. Each of these sweeps
will be performed by qualified personnel.
NOTE: Sweeps 1 and 2 will be coordinated through the NRCS and the
County, however, we understand that USFWS personnel will be available
to perform Sweep 3 if it is deemed necessary. Any mussels located during
the initial two sweeps, if required, will be relocated to areas designated by
USFWS. If "trans-location" of any "moved" individuals is determined to
be necessary at a future time, USFWS will manage this effort.
5. General fill and grading operations will be performed under the observation of
representatives of S&EC and McGill Associates. As necessary, supplemental
erosion and sediment control measures will be employed (as site topography and
limitations permit) to protect existing surfaces from erosion and surface waters
from sediment loads associated with construction.
6. Technical Specifications included in our plan have called for the utilization of
borrow materials (including river bed borrow consisting of sand, gravel, cobble,
and small boulders) for the reconstruction of the lower bank zone. These
materials in conjunction with the previously described in-stream structures and
toe stabilization measures will allow for a "jump start" of the channel and bank
substrate with materials which we understand will be favorable to population
(indirect or through relocation) of the repair reach with AE mussels.
Additionally, as these construction materials typically contain few fines
13
I
Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
(including silt), their placement is less likely to affect the adjacent waters in
terms of sediment loads detrimental to the AE mussel.
7. REGULATORY REQUIREMENTS
401 WATER QUALITY CERTIFICATION (Mandatory Requirement based on expected
Certification conditions) - The following mandatory conditions apply to all repair sites:
1. Erosion & Sediment Control Practices
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.
2. 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.
3. 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.
14

Campground Site - Stream Repairs & Bank Stabilization Plan June 8, 2005
Haywood County Invitation # HC-103 McGill Associates, P.A.
4. 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.
5. 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, unless authorized under Division of Land Resources Erosion
and Sediment Control approval. 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.
6. 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.
7. The channel must 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.
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.
8. 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 are not permitted because they block the floodplain, constrict and

accelerate flood flows, and often fail or impede drainage during large flood
events.
9. 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.
10. 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.
11. As long-term stream stability is a concern with this type of work, it is strongly
recommended that woody vegetation be established along stream banks where
possible. Any riparian vegetation planting should be performed in accordance
with the Guidelines for Riparian Buffer Restoration.
12. Monitoring - The Permittee shall examine the stabilization work done under
this Certification on an annual basis for three (3) years following the
completion of the restoration efforts. This field evaluation should note the
condition and stability of the measures installed and how well the repair is
holding up. A written report must be provided to DWQ's Asheville Regional
Office by June 1 of each year. The report must describe inspection results,
include digital photographs, list the date of inspection, and describe any
needed repairs or corrections.
13. The permittee will provide on-site supervision of stability work including, but
not limited to bank re-sloping, in-stream structure placement, and riparian
zone re-establishment by an appropriately trained individual.
14. If pasture along the stream is to be used for grazing, the permittee must inform
the appropriate landowners that cattle should be prohibited from damaging
riparian areas and from de-stabilizing the stream banks and channel.
15. Diffuse Flow - All constructed storm water 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.
16. Water Quality Certification Notifications - The permittee must provide a
copy of this issued Water Quality Certification and attached cover letter to
each property owner where the approved work will be performed.
17. Turbidity Standard -The turbidity standard (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.

Do not backfill over porous, frozen, or spongy subgrade surfaces.
Employ a placement method that does not disturb or damage other
work. Place backfill and fill in loose level lifts not to exceed six
inches in thickness before compaction. Make gradual grade
changes. Blend slope into level areas. Slope grade minimum 2
inches in 10 feet, unless noted otherwise.
c. If the surface of any layer becomes too hard and smooth for proper
bond with the succeeding layer, it shall be scarified parallel to the
axis of the fill to a depth of not less than 2 inches before the next
layer is placed.
d. The top surfaces of embankments shall be maintained
approximately level during construction, except that a crown or
cross-slope of not less than 2% shall be maintained to insure
effective drainage, and except as otherwise specified for drain fill
zones. If the Drawings or Specifications require, or the Engineer
directs, that fill be placed at a higher level in one part of an
embankment than another, the top surface of each part shall be
maintained as specified above.
e. Dams and other embankments shall be constructed in continuous
layers from abutment to abutment except where openings to
facilitate construction or to allow the passage of stream flow
during construction are specifically authorized in the Contract.
Embankments built at different levels as described under
SECTION 6.6-d or -e above shall be constructed so that the slope
of the bonding surfaces between embankment in place and
embankment to be placed is not steeper than 2 feet horizontal to 1
foot vertical. In areas where existing embankment is to be
flattened, topsoil shall be removed as described in SECTION 5.5
(Excavating). New embankment material shall be benched into
existing slope as shown on the plans. Short bench levels shall be
formed to a slope of 211:1 V or flatter, based on existing slope
conditions as determined by the Engineer at the time of
construction. Benching shall be constructed in such a fashion as
to inhibit the formation of preferential planes of slope failure. The
bonding surface of the embankment in place shall be stripped of
all loose material, and shall be scarified, moistened and
recompacted when the new fill is placed against it as needed to

The following specifications and methods form a part of this
specification:
NCDENR - Erosion and Sediment Control Planning and Design
Manual
When the specifications or drawings differ from the requirements of the
above-referenced documents, the more stringent requirements shall
apply.
10.4 GENERAL
Permanent seeding shall be executed in temporary lined areas and all
other areas which are disturbed during construction activities. In areas
where Channel Protective Lining will be installed, seedbed preparation
and seeding shall be performed prior to the placement of erosion
control matting (See SECTION 7 - Channel Protective Linings).
10.5 SEEDBED PREPARATION
Complete grading before topsoiling or preparing seedbeds. Avoid
' creating steep slopes. Excess stockpiled topsoil not used in
construction of Channel Protective Lining shall be redistributed across
areas to be seeded. Where topsoil is unavailable, seedbeds may be
' prepared directly on the exposed finished grade or topsoil may be
imported.
1

J

If topsoil is used, it should be spread to a uniform depth of four to six
inches and bonded to the subsoil by loosening with a disc, harrow, or
chisel plow. Areas where seeding will occur on exposed finished grade
shall be disked or harrowed to ensure soil aeration and to increase the
surface roughness prior to planting.
Apply lime and fertilizer evenly across seedbed and work into the top
4-6 inches of soil by discing or other suitable means. Operate
machinery on the contour.
Rework the surface if soil becomes compacted or crusted prior to
seeding. Complete seedbed preparation by breaking up large clods and
raking into a smooth, uniform surface. Fill in or level depressions that
can collect water.
10.6 SEEDING
Apply permanent seeding to seedbed after preparation is complete. Use
certified seed for permanent seeding whenever possible. Certified seed
is inspected by the North Carolina Crop Improvement Association. It
meets published North Carolina Standards and should bear an official
"Certified Seed" label. Broadcast seed into a freshly loosened seedbed
that has not been settled by rainfall. Mulch must be used on slopes
4H:1 V or steeper and in areas when concentrated water may flow.
Anchor mulch with netting in areas subject to concentrated flow. In

fabric shall extend into the ground as shown in the plans.
If possible, the filter fabric shall be cut from a continuous roll to avoid
the use of joints. When joints are necessary, securely fasten the filter
cloth only at a support with overlap to the next post.
Silt fences shall be inspected weekly and after each significant storm (1
inch in 24 hrs.). Any required repairs shall be made immediately.
Sediment shall be removed when it reaches 1/3 height of the fence or 9
inches maximum. Dispose of the sediment in the designated disposal
area.
11.6 PUMP AROUND OPERATIONS
The work covered by this item includes: providing, installing,
maintaining, and removing all equipment and materials associated with
the pumping of channel flow around work areas and dewatering zones
during construction. The Contractor shall utilize the specified and
appropriately sized pumps to convey the diversion of water flow away
from the work area without creating a flood hazard or scour. The
Contractor is responsible for determining (based on the direction of the
Engineer) the location of coffer dams, pumps, discharge hose route,
stilling basins, splash pads, and period of operation prior to the
initiation of any pumping. An attempt will be made to complete all
grading, channel shaping, in-stream structure construction, and
stabilization for each section within one day. If work for any particular
section cannot be completed in one day, a 24-hour pumping operation
will be set up and maintained to facilitate the construction schedule.
Bypass Pump
The pump used to convey the stream flow around the work area during
construction should be capable of pumping and discharging an
estimated 15 gallons per minute. The Contractor is responsible for
selecting a properly sized pump. This unit should be a silent and self-
priming model with a self-contained fuel tank large enough to facilitate
a 24-hour pumping operation. The pump should also be matched with
the necessary footage of flexible or ductile hose and appropriately sized
fittings.
Dewatering Pump
A second pump shall be used to dewater the work area between the
dams. The pump must be of sufficient size to dewater the work area
and pump that water from the bottom of the work area to the special
stilling basin. The pump should be matched with the necessary footage
of hose and the required fittings.
Special Stilling Basin
The special stilling basins are covered in detail under the "Special
Stilling Basins" section.
Temporary Splash Pad
A temporary splash pad shall be used to dissipate energy from the
discharge from the bypass pump. Alternatively, check dams may be
modified and used for this purpose as determined by the Engineer.
11.7 SPECIAL STILLING BASINS
The work covered by this section consists of furnishing, placing, and
removing special stilling basins as directed by the plans and the
Engineer. The special stilling basins shall be used to filter pumped
water during construction. The quantity of special stilling basins may
be increased, decreased, or eliminated entirely at the direction of the
Engineer. Such variations in quantity will not be considered as
alterations in the details of construction or a change in the character of
work.

The special stilling basins shall be a water permeable fabric bag that
traps sand, silt, and fines from the sediment laden water entering. The
filter fabric shall meet the requirements of Section 1056 for Type 2
Fabric.
The special stilling basin shall be a bag constructed to a minimum size
of 10' X 15' made from nonwoven fabric. There shall be a sewn-in 8
inch spout for receiving pump discharge. The bag seam shall be sewn
with a double needle machine using a high strength thread. The seants
shall have a minimum width strength of 601b/in (ASTM D-4884).
Millet
5-10-10 fertilizer shall be applied to all disturbed areas at a rate of 21
pounds per 1000 square feet (21 lbs./1000 sq.ft.), and mulching shall
consist of small grain straw applied a rate of 70 pounds per 1000
square feet (70lbs./1000sq.11.). Mulch shall be anchored by roving or
netting.

The fabric used to construct the bag shall be stabilized to provide
resistance to ultra-violet degradation and meet the following
specifications for flow rates, strength, and permeability:
' Weight 8 ozlyd (ASTM D-3776)
Grab Tensile 200 lb (ASTM D-4632)
Puncture 130 lb (ASTM D-4833)
Flow Rate
Permittivity 80 gpm/sf (ASTM D-4491)
1.51/sec (ASTM D-4991)
W Resistance 70 % (ASTM D4355)

The special stilling basins shall be placed so the incoming water flows
through the bag without causing erosion. The bag will rest on
Nonwoven Type 2 filter fabric. The contractor will grade the bed to
ensure that the filtered water exits at the desired location. The exit
location shall be chosen to prevent erosion. The neck or spout of the
bag shall be tied tightly to prevent water from exiting the bag without
passing through the walls. The special stilling basin shall be disposed
of and replaced when it is'/. full of sediment, becomes tom or
punctured, or is unable to filter sediment at a reasonable flow rate.
Approval from Engineer must be received prior to removal and
replacement of special stilling basins. Contractor is responsible for
providing the necessary quantity of special stilling basins for the
duration of the project.
1 11.8 TEMPORARY SEEDING
The Contractor shall provide all labor, materials, tools, and other items
necessary to provide temporary seeding in accordance with State and
local Standards.
Areas where no substantial or significant progress is made for more
than 15 days shall be temporarily seeded as shown on the Drawings and
specified herein. All areas must be seeded, mulched, and anchored
unless written approval is granted by the Owner. Incidental grading
shall not constitute substantial or significant progress in construction
activity.
Seeding and mulching shall be done immediately following
construction. All disturbed areas shall be dressed to a depth of 8
inches. The top 3 inches shall be pulverized to provide a uniform
seedbed.
Agricultural lime shall be applied at a rate of 95 pounds per 1000
square feet (95 lbs. /1000 sq.ft.) immediately before plowing.
Grass seed shall be applied at the following rate:
