Approval of 401 Water Quality Certification with Additional Conditions MZ
Dear Mr. & Mrs. Shuvart and Mrs. Reid:
You have our approval, in accordance with the attached conditions and those listed
below, to place fill within or otherwise impact 400 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 March 16, 2006. After
reviewing your application, we have decided that the impacts are covered by General
Water Quality Certification Number(s) 3495 (GC 3495). The Certification(s) allows you
to use Nationwide Permit(s) 13 & 27 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 stated in your application. (Nothing in this approval
should be interpreted as giving permission to remove bedload material form the
existing channel, nor allowing for the construction of berms which would not
allow the stream access to it's floodplain.) If you change your project, you must
notify us and you may be required to send us a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is
thereby responsible for complying with all conditions. If total fills for this project (now or
in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval

requires you to follow the conditions listed in the attached certification and any
additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific
and general conditions of this Certification (or Isolated Wetland Permit) are met.
No other impacts are approved including incidental impacts:
Amount
Approved (Units) Plan Location or Reference
Stream 400 linear feet) N. Pacolet 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.
Shuvart Property
Page 3 of 6
April 24, 2006
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. 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.
7. 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.
8. 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.
Shuvart Property
Page 4 of 6
April 24, 2006
9. 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.
10. 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.
11. 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.
12. Disturbed stream banks and a 25-foot vegetated zone, or the widest width that is
practical under the site conditions, should be restored where possible along the
construction sites to natural riparian conditions with native trees and shrubs (e.g.,
silky dogwood, rhododendron, dog hobble, red maple, silky willow, tag alder, black
willow, sycamore) to provide long-term bank stability and stream shading. Note,
silky dogwood, silky willow and black willow can be planted as live stakes collected
during the dormant growing season. Cuttings should be randomly planted on four
(4) foot centers from the waters edge to the top of the bank. Trees should be planted
on ten (10) to twelve (12) foot centers. Stream banks in these areas should also be
seeded with a native annual and perennial seed mix with a temporary nursery crop
of wheat, millet or other grain.
13. 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.
14. 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.
15. Riparian Zone Replanting
A 25 foot vegetated zone must be established along streams through the entire
property. Planting of vegetation within 25 feet of the streambank must be done in
a manner consistant with the Guidelines for Riparian Buffer Restoration
immediately following construction. (Please see attached.)
Shuvart Property
Page 5 of 6
April 24, 2006
16. Deed Restrictions
Deed restrictions or conservation easements 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.
17. Turbidity Standard
The turbidity standard of 10 NTUs (Nephelometric Turbidity Units) shall not be
exceeded as described in 15 A NCAC 2B. .0200. Appropriate sediment and
erosion control practices must be used to meet this standard.
18. No Sediment and Erosion Control Measures in Wetlands
Sediment and erosion control measures shall not be placed in wetlands or waters
to the maximum extent practicable. If placement of sediment and erosion control
devices in wetlands and waters is unavoidable, they shall be removed and the
natural grade restored within six months of the date that the Division of Land
Resources or locally delegated program has released the project.
Violations of any condition herein set forth may result in revocation of this Certification
and may result in criminal and/or civil penalties. The authorization to proceed with your
proposed impacts or to conduct impacts to waters as depicted in your application and
as authorized by this Certification, shall expire upon expiration of the 404 or CAMA
Permit.
If you do not accept any of the conditions of this Certification (associated with the
approved wetland or stream impacts), you may ask for an adjudicatory hearing. You
must act within 60 days of the date that you receive this letter. To ask for a hearing,
send a written petition, which conforms to Chapter 150B of the North Carolina General
Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh,
N.C. 27699-6714. This certification and its conditions are final and binding unless you
ask for a hearing.

8. Describe the existing conditions on the site and general land use in the vicinity of the project at
the time of this application:
The proposed project site consists of woodland areas, pasture and agricultural land, and rural
residences. The North Pacolet River was significantly damaged by hurricanes Francis and Ivan
in September, 2004. This particular site is located on the Schuvart property at the outside of a
broad, eastward arching meander of the North Pacolet River. Many damaged areas along the
North Pacolet River and throughout the southeastern United States were repaired through
funding provided by the Natural Resource Conservation Service (MRCS) as part of the
Emergency Watershed Protection (EWP) program. The NRCS program required economic
justification for discrete repairs and primarily addressed flood damaged areas adjacent to
homes or commercial agricultural areas. As a result, some severely eroded streambanks
adjacent to undeveloped land were not addressed by the EWP program.
The State of North Carolina has recently provided funding through the DENR Division of Water
Resources (DWR) Water Resources Development Project Grant program for damaged areas that
were not addressed by the EWP program. The Schuvart site has been identified by the Polk
County Soil and Water Conservation District as one area eligible for DWR funding. The project
area consists of approximately 400 feet of eroding, overhanging streambank located on the
cutbank, or outside of the riverbend described above and indicated in Figures land 2. The
North Pacolet River is classified as "C" waters throughout the project area.
Describe the overall project in detail, including the type of equipment to be used:
SUMMARY
Streambank slopes located on the outside of the river bend (west and southwest) of the North
Pacolet will be made less steep with the use of a track mounted excavator and will be adjusted to
a final slope no steeper than three horizontal to one vertical in all areas except where large
living trees are too close to the existing bank to allow for such a slope. In these areas the slope
will be softened as much as possible with out damaging the large trees that are holding the bank
in place. Root wads will be installed in these areas where the bank is steeper to deflect and
dissipate stream flow.
The toe of the repaired slope will be reinforced in higher stress areas with large angular
boulders. In these areas one row of boulders will be placed in a footer trench. The footer trench
will be lined and the rock toe protection will be backed with filter fabric and another tier of
large boulders will be placed on top of the footer rock and set back approximately one-two feet
in order to match the slope of the streambank. Void spaces behind the footer and tiers of rock
will be back-filled with material that was excavated during the installation of the footer trench.
When backfilling is complete excess filter cloth protruding from between the boulders and the
backfill will be trimmed to an elevation slightly higher than the elevation of the top of the
boulder toe protection.
Page 7 of 18
Live fascines will be buried in the streambank just above the boulder toe protection and around
rootwad structures where feasible. Fascines will consist of bundles of a variety of live stakes
taken from native species of trees. The live cuttings used for fascine bundles will be no larger
than one inch in diameter and will be approximately six to eight feet in length. Tips of live
cuttings will be oriented in the same direction but cut to varying lengths before placement in the
fascine bundles. Fascine bundles will be bound together with heavy biodegradable twine and
placed in trenches with the tips facing in an upstream direction. The live Fascines will take
root and quickly begin to anchor and further strengthen the toe of the streambank slope soon
after installation.
After the streambank slope is adjusted, and toe protection consisting of boulders, rootwads and
fascines are installed, disturbed areas within the project area will be hand seeded with annual
rye or similar grain. Coir or Jute matting will be installed over the areas of bare soil, trenched
in on all sides and held down by either wooden or live stakes. Hydro-seeding of these areas
with a native seed mix will follow, and caution will be used to keep seed, mulch and tackifiers
out of the river and above bankfull elevation in order to reduce the risk of eutrophication.
Finally the remainder of the streambank will be planted with a variety of native bare-root and
live-stake trees and shrubs to a width no less that 30 feet from the waters edge along the entire
reach of the project area. All plantings will be watered in after installation and subsequently,
as needed. These plantings will re-establish the riparian vegetation within the project area,
providing a more stable streambank and future shading of the river channel. Live stakes and
cuttings will be purchased dormant and, if necessary, kept in a large walk in cooler until the
site is ready to be planted in early spring.
The project will include removal of debris (i.e. large trees) that are currently obstructing water
flow and limiting hydraulic capacity of the river channel. Some of these trees and their root
balls will be used for bank stabilization and as aquatic and terrestrial habitat as rootwad
structures in several locations within the project area. Rootwads are planned for use where the
existence of very large live trees will not allow grading of the streambank to a preferable three
horizontal to one vertical slope. Trees selected for rootwads will be cut 15 to 20 feet up the
trunk from the roots and sharpened to a point with a chainsaw. In locations were rootwads are
used a trench will be excavated large enough to burry a footer log parallel to the streambank at
the toe of the slope. The rootwad will be inserted sharpened trunk first in to the bank and the
trunk just above the roots will rest on the footer log. The rootwads will be oriented so that
stream flow is deflected away from the streambank to protect large living trees in these
locations. Placement of the rootwads at an angle approximately 75 degrees from the upstream
bank should provide the deflection of streamwater desired to preserve near bank live trees.
The rootwad and footer log will be installed so that the bottoms of the structure extend to the
maximum scour depth of the channel and the top of footer log and bottom of rootwad log are
roughly the same elevation as the stream invert. Rootwad trunks will be inserted into the
streambank by a track mounted excavator so that the root ball is exposed and at least two thirds
of the trunk is buried in the bank. Root wads and footer logs will be backfilled with material
excavated from footer log and root wad trenches and where necessary will be stabilized on
either side with large angular rock or rip rap.
Equipment used to accomplish the above tasks will include: rubber tired back-how / loader,
Page 8 of 18
a track mounted excavator with hydraulic thumb, one or two 15 ton dump trucks, and hand tools.
A wood chipper may be used to reduce the amount of debris to be hauled away from the site and
minimize potential disposal fees. Wood chips may be used to mulch areas beyond the top of
bank
DETAILS
The following activities are proposed within the project area:
An area of the North Pacolet River adjacent to the Schuvart property located in Polk
County, North Carolina has been identified by the Polk County Soil and Water
Conservation District Office as eligible for monies provided by the State of North Carolina
through a DWR grant. The Polk County Soil and Water Conservation District Office and
Altamont Environmental, Inc. (Altamont) plan to stabilize the over-steepened streambank
and restore the riparian buffer along this approximate 400 foot by 60 foot, 0.55 acre site.
Three types of structures are proposed for streambank stabilization at the site: Rootwads,
Rock Toe Protection and Live Fascines. These structures coupled with softening of the
streambank slope should provide a lasting repair that leaves the project area in a more
natural state of equilibrium. Once the streambank is stabilized native species of grasses,
shrubs and trees will be planted on the streambank and disturbed areas of the site.
Site vicinity and general locations of streambank and channel repair areas are provided in
Figure 1. A representative photo with typical construction plans superimposed for the
project area is included as Figures 2. Cross-sections of both the existing streambank and
proposed construction plans are included as Figure 3 and plans for construction of specific
structures are include as Figures 4 and 5. Estimates ofshear stresses within the project
area at elevations ranging from 2 to 9.8 feet were calculated and a proposed cross-section
used for the hydraulic radius calculation are attached at the end of this document.
• Before construction at the site begins, existing live trees and vegetation that are
identified as stabilizing the streambank will be flagged to be left in place. Project area
boundaries will also be identified and marked.
• Some removal of organic and non-native material from the channel may be necessary in
areas where the hydraulic capacity of the stream channel has been reduced based upon
on site observations and evaluation of existing cross-sections.
• Using the track mounted excavator and the backhoe, streambank slopes within the
project area will be adjusted from their near vertical state to a slope no steeper than
three horizontal to one vertical except where large living trees close to the bank
prohibit extensive grading. In these areas rootwad structures will be installed and
slopes will be softened as much as possible. Some adjustment of the slope before
installation of structures will allow for easier access to the project area, will compact
the slope and will eliminate much of the need to access the streambank from the water.
• Debris generally consisting of trees, stumps and woody material will be removed from
the stream channel using the track mounted excavator equipped with a hydraulic thumb.
Some of the larger dead trees will be used as rootwads structures within the project
area pending a geotechnical sieve analysis. Rootwad structures are not recommended
in areas where there is less than 15 percent silt and clay content in streambank soils.
Page 9 of 18
The Sieve analysis will be completed prior to construction to confirm that necessary fine
sediments exist in soils within the project area.
• If possible an excavator with a long-arm or long-stick boom will be used for this project
to reduce or eliminate the need to enter the stream channel. The excavator to be used
for this project will be a 300 series or comparable machine. Woody debris removed
from the channel will be reused as rootwad structures or disposed of either as firewood,
chipped into mulch, hauled to an appropriate landfill or some combination of the three.
• For streambank areas where rock toe protection is used, a footer trench will be
excavated at the toe of the slope. The footer trench will be excavated to a depth of
approximately two feet or deep enough to bury each footer rock to a depth equal to
three-quarters of its thickness. Ideal dimensions for large angular rock to be used at the
site are five feet by three feet by three feet or larger. Footer trenches will be dug in a
downstream to upstream sequence in order to limit the amount of sediment discharged
to the stream and limit the flow of water into the trench. Footer trenches will be dug in
sections equal to the width of the filter cloth to be used for the project. Completing the
project in sections will limit the number of times the trench will have to be re-excavated
due to sediment washed in by the river. Footer trenches at the upstream and
downstream extents of the repair area will be keyed in the streambank so that flow
during periods of high water cannot get behind the rock toe protection and compromise
the structure.
• After a section of footer trench is dug, filter cloth will be placed in the trench and a
sufficient amount of cloth will be extended up the streambank to back the footer and next
tier of rock once it is placed. Footer rock of a size described above will then be placed
in the trench securing the bottom of the filter cloth in place.
• After the footer rock is placed the filter cloth will be held up so that it backs the footer
rock while the void behind the footer is backfilled with material that was excavated from
the trench.
• Again the filter cloth will be laid on the streambank while the first tier of rock is placed
atop the footer. This first tier of rock will be placed partially on the footer and partially
on the backfill, set back in a manner to match the three to one slope of the streambank.
• Once the first tier of rock is placed on the footer, the filter cloth will again be held up so
that the remainder of the rock structure can be backfilled.
• When construction of the rock toe and rootwad structures is complete, a trench
approximately one foot by one foot will be installed just above the rock toe protection
structure. Live fascines will be installed in the trench and the trench will be backfilled.
Fascine trenches will be excavated to dimensions slightly smaller than the fascine
bundle, so that the top of the fascine is exposed. Live stakes will be driven through the
fascines to secure them in place. Subsequent growth of the fascines will further
stabilize the toe of the streambank as roots interlock with soil, matting and rock in this
location.
• After streambank slopes are adjusted, construction of rock toe and rootwad structures is
completed and fascines are installed, all disturbed areas will be hand seeded with
Page 10 of 18
annual rye grass or a similar grain. Coir mat will be installed over the completed
fascines and bare soil near the toe of the streambank and will extend up the streambank
to approximate bankfull elevation. Jute mat will be used on the upper portion of the
slope to stabilize soils during initial growth of vegetation. On-site temporary seeding
and mulching will occur on the remainder of bare soil within five days of ground
disturbing activities to provide long-term erosion control.
• When the construction portion of the entire project area is complete all disturbed areas
will be hydro-seeded with a native seed mix above typical high water elevation. Care
will be taken to keep seed, mulch, fertilizer and tackifiers out of the stream to prevent
the risk of euotrophication downstream.
Post hydro-seeding, disturbed areas will be planted with a diverse variety of bare-root
and live-stake native plants, shrubs, and trees based on observations made ofplants that
are naturally occurring within the stream corridor or could exist with in the region.
Planting will conform to the guidelines prescribed in the NCDENR Ecosystem
Enhancement Program, Guidelines for Riparian Buffer Restoration. Re-seeding will be
conducted, as necessary, with a native annual and perennial seed mix with a temporary
nursery crop of wheat, millet, or other grain. Woody vegetation will be planted during
the appropriate planting season or will be kept dormant in coolers until planted
Planting is expected to take place no later that early May.
Stabilization of streambanks will require placement of material in wet conditions. In such
cases, sand bags, or the equivalent, will be used to deflect water flow away fi°om the work area,
as well as prevent water from accumulating in the work area. Standard erosion and
sedimentation control measures will be utilized throughout the project.
Care will be taken to avoid adverse affects to adjacent or downstream property owners.
At the work site, work shall proceed from downstream to upstream to reduce sediment loading.
Staging areas for equipment and material will be placed in upland areas away from surface
water and outside of the floodplain. Work will proceed as follows at the work area (as
applicable).
1. Flag the work limits.
2. Mark live trees and shrubs to be protected.
3. Construct temporary construction entrance / exits, where necessary.
4. Place erosion control fencing and other protective measures as necessary.
5. Inspect and maintain repairs.
Explain the purpose of the proposed work:

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

8. Describe the existing conditions on the site and general land use in the vicinity of the project at
the time of this application:
The proposed project site consists of woodland areas, pasture and agricultural land, and rural
residences. The North Pacolet River was significantly damaged by hurricanes Francis and Ivan
in September, 2004. This particular site is located on the Schuvart property at the outside of a
broad, eastward arching meander of the North Pacolet River. Many damaged areas along the
North Pacolet River and throughout the southeastern United States were repaired through
funding provided by the Natural Resource Conservation Service (MRCS) as part of the
Emergency Watershed Protection (EWP) program. The NRCS program required economic
justification for discrete repairs and primarily addressed flood damaged areas adjacent to
homes or commercial agricultural areas. As a result, some severely eroded streambanks
adjacent to undeveloped land were not addressed by the EWP program.
The State of North Carolina has recently provided funding through the DENR Division of Water
Resources (DWR) Water Resources Development Project Grant program for damaged areas that
were not addressed by the EWP program. The Schuvart site has been identified by the Polk
County Soil and Water Conservation District as one area eligible for DWR funding. The project
area consists of approximately 400 feet of eroding, overhanging streambank located on the
cutbank, or outside of the riverbend described above and indicated. in Figures land 2. The
North Pacolet River is classified as "C" waters throughout the project area.
Describe the overall project in detail, including the type of equipment to be used:
SUMMARY
Streambank slopes located on the outside of the river bend (west and southwest) of the North
Pacolet will be made less steep with the use of a track mounted excavator and will be adjusted to
a final slope no steeper than three horizontal to one vertical in all areas except where large
living trees are too close to the existing bank to allow for such a slope. In these areas the slope
will be softened as much as possible with out damaging the large trees that are holding the bank
in place. Root wads will be installed in these areas where the bank is steeper to deflect and
dissipate stream flow.
The toe of the repaired slope will be reinforced in higher stress areas with large angular
boulders. In these areas one row of boulders will be placed in a footer trench. The footer trench
will be lined and the rock toe protection will be backed with filter fabric and another tier of
large boulders will be placed on top of the footer rock and set back approximately one-two feet
in order to match the slope of the streambank Void spaces behind the footer and tiers of rock
will be back-filled with material that was excavated during the installation of the footer trench.
When backfilling is complete excess filter cloth protruding from between the boulders and the
backfill will be trimmed to an elevation slightly higher than the elevation of the top of the
boulder toe protection.
Page 7 of 18
Live fascines will be buried in the streambank just above the boulder toe protection and around
rootwad structures where feasible. Fascines will consist of bundles of a variety of live stakes
taken from native species of trees. The live cuttings used for fascine bundles will be no larger
than one inch in diameter and will be approximately six-to eight feet in length. Tips of live
cuttings will be oriented in the same direction but cut to varying lengths before placement in the
fascine bundles. Fascine bundles will be bound together with heavy biodegradable twine and
placed in trenches with the tips facing in an upstream direction. The live Fascines will take
root and quickly begin to anchor and further strengthen the toe of the streambank slope soon
after installation.
After the streambank slope is adjusted, and toe protection consisting of boulders, rootwads and
fascines are installed, disturbed areas within the project area will be hand seeded with annual
rye or similar grain. Coir or Jute matting will be installed over the areas of bare soil, trenched
in on all sides and held down by either wooden or live stakes. Hydro-seeding of these areas
with a native seed mix will follow, and caution will be used to keep seed, mulch and tackifiers
out of the river and above bankfull elevation in order to reduce the risk of eutrophication.
Finally the remainder of the streambank will be planted with a variety of native bare-root and
live-stake trees and shrubs to a width no less that 30 feet from the waters edge along the entire
reach of the project area. All plantings will be watered in after installation and subsequently,
as needed. These plantings will re-establish the riparian vegetation within the project area,
providing a more stable streambank and future shading of the river channel. Live stakes and
cuttings will be purchased dormant and, if necessary, kept in a large walk in cooler until the
site is ready to be planted in early spring.
The project will include removal of debris (i. e. large trees) that are currently obstructing water
flow and limiting hydraulic capacity of the river channel. Some of these trees and their root
balls will be used for bank stabilization and as aquatic and terrestrial habitat as rootwad
structures in several locations within the project area. Rootwads are planned for use where the
existence of very large live trees will not allow grading of the streambank to a preferable three
horizontal to one vertical slope. Trees selected for rootwads will be cut 15 to 20 feet up the
trunk from the roots and sharpened to a point with a chainsaw. In locations were rootwads are
used a trench will be excavated large enough to burry a footer log parallel to the streambank at
the toe of the slope. The rootwad will be inserted sharpened trunk first in to the bank and the
trunk just above the roots will rest on the footer log. The rootwads will be oriented so that
stream flow is deflected away from the streambank to protect large living trees in these
locations. Placement of the rootwads at an angle approximately 75 degrees from the upstream
bank should provide the deflection of streamwater desired to preserve near bank live trees.
The rootwad and footer log will be installed so that the bottoms of the structure extend to the
maximum scour depth of the channel and the top of footer log and bottom of rootwad log are
roughly the same elevation as the stream invert. Rootwad trunks will be inserted into the
streambank by a track mounted excavator so that the root ball is exposed and at least two thirds
of the trunk is buried in the bank. Root wads and footer logs will be backfilled with material
excavated from footer log and root wad trenches and where necessary will be stabilized on
either side with large angular rock or rip rap.
Equipment used to accomplish the above tasks will include: rubber tired back-how / loader,
Page 8of18
a track mounted excavator with hydraulic thumb, one or two 15 ton dump trucks, and hand tools.
A wood chipper may be used to reduce the amount of debris to be hauled away from the site and
minimize potential disposal fees. Wood chips may be used to mulch areas beyond the top of
bank.
DETAILS
The following activities are proposed within the project area:
An area of the North Pacolet River adjacent to the Schuvart property located in Polk
County, North Carolina has been identified by the Polk County Soil and Water
Conservation District Office as eligible for monies provided by the State of North Carolina
through a DWR grant. The Polk County Soil and Water Conservation District Office and
Altamont Environmental, Inc. (Altamont) plan to stabilize the over-steepened streambank
and restore the riparian buffer along this approximate 400 foot by 60 foot, 0.55 acre site.
Three types of structures are proposed for streambank stabilization at the site: Rootwads,
Rock Toe Protection and Live Fascines. These structures coupled with softening of the
streambank slope should provide a lasting repair that leaves the project area in a more
natural state of equilibrium. Once the streambank is stabilized native species of grasses,
shrubs and trees will be planted on the streambank and disturbed areas of the site.
Site vicinity and general locations of streambank and channel repair areas are provided in
Figure 1. A representative photo with typical construction plans superimposed for the
project area is included as Figures 2. Cross-sections of both the existing streambank and
proposed construction plans are included as Figure 3 and plans for construction of specific
structures are include as Figures 4 and 5. Estimates of shear stresses within the project
area at elevations ranging from 2 to 9.8 feet were calculated and a proposed cross-section
used for the hydraulic radius calculation are attached at the end of this document.
• Before construction at the site begins, existing live trees and vegetation that are
identified as stabilizing the streambank will be flagged to be left in place. Project area
boundaries will also be identified and marked.
• Some removal of organic and non-native material from the channel may be necessary in
areas where the hydraulic capacity of the stream channel has been reduced based upon
on site observations and evaluation of existing cross-sections.
Using the track mounted excavator and the backhoe, streambank slopes within the
project area will be adjusted from their near vertical state to a slope no steeper than
three horizontal to one vertical except where large living trees close to the bank
prohibit extensive grading. In these areas rootwad structures will be installed and
slopes will be softened as much as possible. Some adjustment of the slope before
installation of structures will allow for easier access to the project area, will compact
the slope and will eliminate much of the need to access the streambankfrom the water.
• Debris generally consisting of trees, stumps and woody material will be removed from
the stream channel using the track mounted excavator equipped with a hydraulic thumb.
Some of the larger dead trees will be used as rootwads structures within the project
area pending a geotechnical sieve analysis. Rootwad structures are not recommended
in areas where there is less than 15 percent silt and clay content in streambank soils.
Page 9 of 18
The Sieve analysis will be completed prior to construction to confirm that necessary fine
sediments exist in soils within the project area.
• Ifpossible an excavator with a long-arm or long-stick boom will be used for this project
to reduce or eliminate the need to enter the stream channel. The excavator to be used
for this project will be a 300 series or comparable machine. Woody debris removed
from the channel will be reused as rootwad structures or disposed of either as firewood,
chipped into mulch, hauled to an appropriate landfill or some combination of the three.
• For streambank areas where rock toe protection is used, a footer trench will be
excavated at the toe of the slope. The footer trench will be excavated to a depth of
approximately two feet or deep enough to bury each footer rock to a depth equal to
three-quarters of its thickness. Ideal dimensions for large angular rock to be used at the
site are five feet by three feet by three feet or larger. Footer trenches will be dug in a
downstream to upstream sequence in order to limit the amount of sediment discharged
to the stream and limit the flow of water into the trench. Footer trenches will be dug in
sections equal to the width of the filter cloth to be used for the project. Completing the
project in sections will limit the number of times the trench will have to be re-excavated
due to sediment washed in by the river. Footer trenches at the upstream and
downstream extents of the repair area will be keyed in the streambank so that flow
during periods of high water cannot get behind the rock toe protection and compromise
the structure.
• After a section offooter trench is dug, filter cloth will be placed in the trench and a
sufficient amount of cloth will be extended up the streambank to back the footer and next
tier of rock once it is placed. Footer rock of a size described above will then be placed
in the trench securing the bottom of the filter cloth in place.
• After the footer rock is placed the filter cloth will be held up so that it backs the footer
rock while the void behind the footer is backfilled with material that was excavated from
the trench.
• Again the filter cloth will be laid on the streambank while the first tier of rock is placed
atop the footer. This first tier of rock will be placed partially on the footer and partially
on the backfill, set back in a manner to match the three to one slope of the streambank.
• Once the first tier of rock is placed on the footer, the filter cloth will again be held up so
that the remainder of the rock structure can be backfilled.
• When construction of the rock toe and rootwad structures is complete, a trench
approximately one foot by one foot will be installed just above the rock toe protection
structure. Live fascines will be installed in the trench and the trench will be backfilled.
Fascine trenches will be excavated to dimensions slightly smaller than the fascine
bundle, so that the top of the fascine is exposed. Live stakes will be driven through the
fascines to secure them in place. Subsequent growth of the fascines will further
stabilize the toe of the streambank as roots interlock with soil, matting and rock in this
location.
• After streambank slopes are adjusted, construction of rock toe and rootwad structures is
completed and fascines are installed, all disturbed areas will be hand seeded with
Page 10 of 18
annual rye grass or a similar grain. Coir mat will be installed over the completed
fascines and bare soil near the toe of the streambank and will extend up the streambank
to approximate bankfull elevation. Jute mat will be used on the upper portion of the
slope to stabilize soils during initial growth of vegetation. On-site temporary seeding
and mulching will occur on the remainder of bare soil within five days of ground
disturbing activities to provide long-term erosion control.
When the construction portion of the entire project area is complete all disturbed areas
will be hydro-seeded with a native seed mix above typical high water elevation. Care
will be taken to keep seed, mulch, fertilizer and tackifiers out of the stream to prevent
the risk of euotrophication downstream.
Post hydro-seeding, disturbed areas will be planted with a diverse variety of bare-root
and live-stake native plants, shrubs, and trees based on observations made ofplants that
are naturally occurring within the stream corridor or could exist with in the region.
Planting will conform to the guidelines prescribed in the NCDENR Ecosystem
Enhancement Program, Guidelines for Riparian Buffer Restoration. Re-seeding will be
conducted, as necessary, with a native annual and perennial seed mix with a temporary
nursery crop of wheat, millet, or other grain. Woody vegetation will be planted during
the appropriate planting season or will be kept dormant in coolers until planted.
Planting is expected to take place no later that early May.
Stabilization of streambanks will require placement of material in wet conditions. In such
cases, sand bags, or the equivalent, will be used to deflect water flow away from the work area,
as well as prevent water from accumulating in the work area. Standard erosion and
sedimentation control measures will be utilized throughout the project.
Care will be taken to avoid adverse affects to adjacent or downstream property owners.
At the work site, work shall proceed from downstream to upstream to reduce sediment loading.
Staging areas for equipment and material will be placed in upland areas away from surface
water and outside of the f oodplain. Work will proceed as follows at the work area (as
applicable).
1. Flag the work limits.
Z Mark live trees and shrubs to be protected.
3. Construct temporary construction entrance / exits, where necessary.
4. Place erosion control fencing and other protective measures as necessary.
5. Inspect and maintain repairs.
Explain the purpose of the proposed work:
The work is being conducted by the Polk County Soil and Water Conservation District Office
and Altamont and is being funded through the North Carolina Division of Water Resources
Page 11 of 18
grant. The grant is intended to fund projects in hurricane damaged areas that were not
addressed by the federal Emergency Watershed Protection program. The purpose of the project
in this specific area is to stabilize the streambank and restore and widen the riparian buffer
along the west and southwest banks of the North Pacolet River within the project area and to
slow the progression of erosion of the cutbank into the Schuvart property and Dark Horse Road.

contractors engaged in the implementation of this work both written and verbal instructions of all
Page 14 of 18
impact avoidance statements provided below. All heavy equipment will be kept out of the stream
channel during streambank stabilization work and debris removal except where absolutely
necessary to complete work Disturbance of the channel bottom, streambanks and equipment
access areas shall be held to the minimum necessary to allow for bank stabilization work.
Temporary grass cover shall be planted on all bare soil within S days of ground disturbing
activities. Straw mulch and tall fescue grass will not be used in riparian areas. Herbaceous and
woody shrub and tree vegetation will be installed on the streambank upon completion of bank
stabilization work Altamont will provide a site manager to routinely inspect and supervise
contractor work to help ensure impact avoidance instructions are being followed.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 211 .05 00, 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
hllp:Hh2o.enr.state.ne.us/ncwetlands/strmgide.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.
N/A
Page 15 of 18
2.Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at 1-ittp://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
Amount of Non-riparian wetland mitigation requested (acres): N/A

Streambank Stability Calculations
Find shear stress with z = yRH S
where: y = 62.4 lb/ft3 (density of water)
RH = hydraulic radius (ft)
S = average stream slope (ft/ft)
Calculate shear stress for depths up to the top of bank. Using channel dimensions from a
cross-section measured by Altamont personnel in the field with the proposed 3:1 slope on
the right bank(see attached cross-section), calculate hydraulic radius for the following
depth conditions (*Note: depth measured from deepest part of channel):
• 2 ft;
• 3 ft;
• 4 ft;
• 5ft
• 6ftand;
• 9.8 ft (top of left bank)
