You have our approval, in accordance with the attached conditions and those listed
below, to place fill-within or otherwise impact 275 feet of streams for the purpose of
streambank stabilization at the subject properties, as described within your application
received by the N.C. Division of Water Quality (DWQ) on July 20, 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. 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

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 275 feet -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
July 25, 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:
Page 4 of 6
July 25, 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
July 25, 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 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
401M/etlands Unit web site at http://h2o.enr.state.nc.us/ncwetiands. 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.

procedure as we slowly transition to electronic applications. Please apprise me of any
complications you encounter, whether related to workload, processing times, or lack of a "second
reviewer" as the triage process in Central had previously provided. Also, if you think of ways to
improve this process, especially so that we can plan for the electronic applications, let me know.
Thanks !

R.E.: 404/401 Permit Applications for Haywood EWP Work
Dear Mr. McLendon and Ms. Karoly:
Attached please find the subject applications for two 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
Pigeon River. 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 (Alasmidonta 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, a mussel survey and, if needed, relocation effort prior to commencing
construction. This was specifically suggested by the USFWS and NC WRC representatives at the
June 2nd 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. Kenneth 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've
made with DWQ's regional 401 contact, Mr. Keven Barnett, we have submitted directly to him
his copy of these repair plans and applications. Also, since NC has "waived" fees for these EWP
401s, we have not included any permit fees. Thank you for your attention to these applications.
Sincerely,

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 stream bank on the west 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 stream banks will provide the appropriate protection against
future high water storm events. Access for this repair work is along South Penland Street.
When at all possible, equipment will be kept out of the stream channel and stream
crossings will be minimized. Temporary and permanent herbaceous vegetation shall be
planted on all bare soils within 15 days of ;?round 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://l12o.enr.state.nc.us/ncwetlands/strm,gide.html.
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
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) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be

Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 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 Pigeon River 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 land owner(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
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 #7 - Feed & Seed Site - the Pigeon River (C Waters) - The repair site is
approximately 275 feet in length and is located along the Pigeon River in Haywood
County, NC. This area is located adjoining the Town of Canton's walking/running track
and is approximately 400 feet upstream of the Main Street bridge (near its intersection
with South Penland Road). Please refer to repair plans for photographs, mapping,
imagery, and details of existing site conditions.

Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
Approximately 275 feet of the left (western) channel bank (left and right are referenced
i while looking downstream) was severely damaged through bank erosion and soil loss.
Howard Putnam, Jimmy and Cathy Clampitt, Hilda Hill, Jeffery Peisner, and Ronald and
Patricia Mills own the property where the repair work will be conducted. A
walking/running track runs parallel to the stream bank throughout the site and was
damaged during the storms. Repairs of the damaged track in this area will be performed
by others under a separate contract.
Banks along the repair reach range in height from roughly 12 to 14 feet and are near
vertical in some locations. Based on a review of available snapping and imagery, the
width of bank loss varies from 5 feet to as much as 30 feet along the repair reach.
No repairs have been performed along the repair reach at this time and the existing
(failed) banks are continuing to erode. Little to no available repair materials exists along
this portion of the reach.
Access to the site is not an issue with a single driveway (controlled by the one of the
owners) allowing access from South Penland Street (NC 215). 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 0.39 Acres and is exempt from an Erosion Control Pen-nit from Land
Quality. The Feed & Seed 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).
1 3. TECHNICAL REPAIR DESCRIPTION
On April 1, April 13, and again on May 19, 2005 members of our design team visited the
1 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 bank cross-section while on site. The cross-section
location was selected to typify the existing bank condition along the repair reach. A plan

sketch of the existing site conditions along the typical cross-section was taken along the
repair reach and is shown in the Repair Plans.
We discussed the site conditions (including a description of pre-damage site) with the
landowners (Putnam, Clampitt, Hill, Peisner and Mills). 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 133.2
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 Feed and Seed 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
4

Feed & Seed -Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
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.
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 toe
stabilization reinforcement) would likely be insufficient to withstand future flood flows.
The installation of toe stabilization is necessary along the reach in areas of excessive
scour in order to tie the repaired bank into the existing stabile banks.

t

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.
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 land owners, 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"
location, we estimated the pre-disturbance "channel width" at approximately 120.0 feet.
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 118.8 feet based on
a drainage area of 133.2 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

Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
the reach. Our Repair Plan calls for the incorporation of a single repair option, Option 2.
See the proposed repair cross-sections depicted in the Repair Plan.
Repair Option 2
For Repair Option 2, 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. The Lower Bank Zone will tie into the Mid-Bank
Zone as depicted on the Repair Plan.
Grading & 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.
The Mid-Bank Zone should be similarly graded (or constructed) with the
previously described materials at a slope of not in excess of 3H:1 V 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
Mid-Bank Zone.
NOTES:
1. The elevations described in the repair cross-section are typical and
intended to describe existing and repaired bank conditions at a location
coincident with the measured field cross-section.
2. The vertical datum to which this is applied (existing top of bank) and the
vertical and horizontal distances depicted in the repair cross-section are
typical and should be verified and adjusted as necessary along the length
of the repair reach.
r 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-
1 7

Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005

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.
Toe Stabilization Measures
"1

Toe stabilization along the repair banks will be constructed 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 1.511:1 V) will improve stability and reduce the potential for future scour
and piping (and resulting failure).
The exact location and extent of toe stabilization measures will be determined by
the designer at the time of construction, however areas typically in need of such
supplemental protection include areas of existing scour (where sub-grade
reconstruction would be difficult), near existing large diameter trees (having
experienced undercutting) which are to be maintained, and at the upstream and
downstream repair limits (where tie-in to undisturbed banks is needed). 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). 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.

D

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.

Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
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
increase the potential for the desired 5-year survivability density of at least 260
stems per acre. The planting plan will include a minimum of five of the nine tree
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 in order
to improve potential for the desired 5-year survivability. The planting plan will
include a minimum of three of the seven shrubs listed in the planting schedule.
Live stakes are specified and will be planted on a spacing of 3 ft. by 3ft.
consisting of Black Willow, Silky Willow, and Silky Dogwood species randomly
intermixed. Live stakes will be cut and installed as shown in the planting details.
A representative of S&EC will be on site to observe and direct planting efforts
associated with the buffer restoration. Substitution of tree, shrub, and live stake
species must be approved in advance by the designer.
Temporary and/or permanent seeding measures (German millet, rye grass, or the
most appropriate erosion control grass as dictated by the season or region) will be
' applied to. areas disturbed during grading operations to allow for localized
stabilization while riparian species establish themselves.

6. APPALACHIAN ELKTOE MUSSEL CONSIDERATIONS
As identified and described by the US Fish and Wildlife Service, a 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 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 surveys.
9
Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
' As previously described, a 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 six
(6) are located in designated Critical Habitat. Four (4) of these sites had individual
Appalachian Elktoe mussel specimen present. A total of five (5) individual mussels were
found during the TCG survey. The greatest number of specimens found at a single repair
site was two (2) Appalachian Elktoe mussels. 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.

1 10
Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
5. Immediately (as soon as possible) re-vegetate construction/access areas with
appropriate native flora after restoration efforts are completed.
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 the
adjacent Track site as well as other sites within the Pigeon River subbasin. Specifically,
1 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).
' 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
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
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. 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
12
' Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
' 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
(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
' 13
' Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
' 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.
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
' 14
Feed & Seed - Stream Repairs & Bank Stabilization Plan July, 2005
Haywood County Invitation # HC-104 McGill Associates, P.A.
' 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 establishe
possible. Any riparian vegetation planting should be performed in accordance
with the Guidelines for Riparian Buffer Restoration.
' (http://h2o.enr.state.nc.us/M/pdf/buffers.pdf )
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 I" 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 prohib
riparian areas and from de-stabilizing the stream banks and channel.

i7

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 15A NCAC 213 .0200. Appropriate
sediment and erosion control practices must be used to meet this standard.
Finally, pending receipt of a final 404 Permit and 401 Certification, copies of these issued
documents and the associated conditions and comments provided by commenting
agencies (when available) will be included in all final contractor packages that will be
used for construction of the repairs. All regulatory requirements and the measures
outlined in this document will be fully discussed with the chosen contractor and the
inspectors for McGill and S&EC before any construction begins. During actual
construction, inspectors will direct contractors to observe and apply good construction
practices and the requirements described in this document.

6.5 PREPARATION
Compact subgrade to density requirements for subsequent backfill
materials. Cut out soft areas of subgrade not capable of compaction in
place. Backfill with ordinary fill material and compact to density equal
to or greater than requirements for subsequent fill material.
Earth fill in repaired channel banks and other structures shall be placed
so as to meet the following additional requirements:
a. The distribution of materials throughout each zone shall be
essentially uniform and the fill shall be free from lenses, pockets,
streaks, or layers of material differing substantially in texture or
gradation from the surrounding materials.
b. Backfill areas to contours and elevations with unfrozen materials.
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.
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.
e. Repaired channel banks 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, unless otherwise specified on the Contract Drawings.
New embankment material shall be benched into existing slope as
shown on the plans. Short bench levels shall be formed to a slope
of 2H:1 V or flatter, based on existing slope conditions as
determined by the Engineer at the time of construction, unless
otherwise specified on the Contract Drawings. 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 insure a good bond with the new fill
and to obtain the specified moisture content and density in the
junction of the in-place and new fill. Any variation to this method
of tying new fill into the existing filled bank shall be determined
in the field at time of construction by the Engineer.
6.7 COMPACTION AND QUALITY CONTROL
For backfill operations, compaction shall be performed using tracked
equipment as directed by the Engineer. Compaction greater than that
provided by tracked equipment may be deemed necessary by the
Engineer based on site or soil conditions. Provide compaction as
directed by the Engineer. Lift thickness shall not exceed 6".
