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.

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.
Caldwell County:

September 2, 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 30-foot vegetated zone (as required under the ORW
regulations), 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
Caldwell County:
Page 5 of 6
September 2, 2005
banks in these areas should also be seeded with a native annual and perennial seed
mix with a temporary nursery crop of wheat, millet or other grain.
14. If pasture along the stream is to be used for grazing, a fence must be constructed
outside of the riparian zone and the stream to prevent livestock from entering these
areas.
15. Diffuse Flow
All constructed stormwater conveyance outlets shall be directed and maintained
as diffuse flow at non-erosive velocities through the protected riparian zones
such that it will not re-concentrate before discharging into a stream. If this is not
possible, it may be necessary to provide stormwater facilities that are considered
to remove nitrogen. This may require additional approval from this Office.
16. Riparian Zone Replanting
Replanting of vegetation within disturbed areas located within 25 feet of the
- streambank associated with any land disturbing activity, repair, replacement
and/or maintenance must be done in a manner consistant with the Guidelines
for Riparian Buffer Restoration immediately following construction. (Please
see attached.)
45. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained
jurisdictional wetlands, waters and protective woody riparian zones in order to
assure compliance for future wetland, water and buffer impact. These
mechanisms shall be put in place prior to impacting any wetlands, waters and/or
buffers approved for impact under this Certification Approval and Authorization
Certificate. A sample deed notification can be downloaded from the
401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of
the sample deed notification may be modified as appropriate to suit to this
project.
17. Turbidity Standard
The turbidity standard of 50 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.

1. PROJECT PURPOSE AND DESCRIPTION
The purpose of this project is to stabilize and/or repair eroded and unstable
streambanks along the stretch of Yadkin River on or adjacent to property off of
Richland Road damaged during the storms in September 2004. The eroded
streambanks have vertical banks, migrated, and are in danger of future failure in the
event of another storm flow. With consent of the landowners and charged to us by
Caldwell County, North Carolina, the proposed design is intended to return the
damaged banks as "close as possible" to the original pre-disturbance condition. It is
important that appropriate construction methods be utilized during the repair
construction to protect local and downstream habitat. The continued sedimentation
and erosion from this 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 is under the
Natural Resource Conservation Service (NRCS) Emergency Watershed Protection
(EWP) program to protect existing property and structures. NRCS is the funding
agency and Caldwell County 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. 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
Appalachian Environmental Services (AES). This site is one of six similarly
damaged sites selected for repair in Caldwell County as part of Caldwell County bid
invitation. Each of these sites is considered independent of one another due to their
physical separation.
2. Site Description
Richlands Site - Yadkin River: The repair site is approximately 300 feet of right and
left bank on the Yadkin River in Caldwell County, North Carolina. This area is
located on Richland Road approximately 2.6 miles from the junction of Richland
Road and US 321 North. Please refer to repair plans for photographs, mapping,
imagery, and existing site details.
Approximately 300 feet of stream was damaged during the storms of 2004. The
stream has moved approximately 40 feet from its original location and original
channel was filled with boulders, cobble and sand. The current NC DOT Bridge
crossing the Yadkin River at the upstream limit of the project is directing the flow of
water into the left stream bank. The current location of the stream is eroding the left
bank and eating away pasture land. A lack of over story species was noted on the
site. Currently there are horses in the pasture and the stream is not fenced out.
Damaged banks along the repair reach range in height from 2 to 6 feet and are near
vertical in some locations. Based upon the existing stream location and available
mapping and imagery, width of channel movement varies from 25 to 40 feet along
the repair reach.
2
No stream bank repairs have been made to this point although at least two high flow
events have occurred since the storms of 2004 which continue to erode the banks
along this reach. There are a limited amount of natural repair materials along this
reach. These materials are boulders and cobble deposited as a result of the storms
of 2004.
Access to the site is not an issue as the site is adjacent to Richland Road and
staging area will be pasture land. Overhead utility lines may be present along the
project reach and any utilities should be located and marked by contractor prior to
construction. The disturbed area for the proposed site is .69 acres and is exempt
from an Erosion Control Permit from Land Quality. The Richlands Site work
described in the repair plan will need to be permitted by the U.S. Army Corps of
Engineers (Section 404) and N.C. Department of Environment and Natural
Resources, Division of Water Quality (Section 401).
3. Technical Repair Description
On July 14 and July 15, 2005 members of our design team visited the repair site to
gain an understanding of current site conditions and perform a general site
characterization. While on site, we observed characteristics of the site and
surrounding area, verified surface and channel flow conditions, and observed
existing property boundaries, site accessibility, and existing water conveyance
structures. During these site visits, we observed eroded stream banks along the
repair reach to typify failed bank height, slope, vegetation and general site
conditions.
While on site we observed channel and bank conditions upstream and downstream
of the repair reach. Using county GIS information and in-field measurements, site
data was collected along the repair reach. Cross sections were field measured on
site. The cross sections typify the existing site condition and a general condition of
cross section either upstream or downstream from damaged site. A site plan of the
existing site conditions along the repair reach is shown in the repair plans.
We discussed site conditions with the project owner (Caldwell County), and project
funding party (NRCS). Photographs were taken of the project site and field notes
taken for the preparation of our design.
Available site mapping was used to locate the pre storm location of stream and
structures. Upon completion of our field visits, data collected in the field was meshed
with current mapping data to develop a preliminary site plan for the project. A
proposed site plan was also developed as part of the preliminary site plan. This
preliminary site plan was discussed with representatives for Caldwell County and
NRCS. The proposed site plan includes plan view, typical repaired bank cross
sections, construction details for typical site features, construction specifications, and
planting recommendations for the proposed repairs.
4. DESIGN CONSIDERATIONS
3
A range of possible repair options were weighed for the Richlands Site. The use of
soil bioengineering, gabions, rip rap, dead woody materials, vegetative stabilization
and in-stream flow modification structures were analyzed. Stabilizing the site in place
versus returning the site to its pre-storm location was also analyzed.
Throughout the process our design team kept in mind the feasibility of utilizing
techniques that would be contractor friendly and could be easily modified or refined
in the field by designer based upon site conditions that could be encountered during
construction.
Materials and methods for construction are commonly used and readily available.
The recommended repairs have been designed to withstand typical channel
discharges and erosive channel forces. Traditional bank armoring practices use
stone or other armored structures to provide protection. Although effective these
practices do not take into account the required volume of stone and does not provide
any natural habitat for wildlife. Dead woody material including dead trees and root
wads provide a more natural alternative to armoring structures, but our staff has
found over the years that in high flow events in the mountains of North Carolina that
dead woody material has a very low success rate where velocities of the stream
channel are significantly increased. Soil bioengineering includes using living plants
as structural components. Certain plant types including black willow root quickly to
begin stabilizing the soil. When used in conjunction with in-stream flow modification
structures including j-hook vanes. Soil bioengineering provides a sound armor of the
streambank by creating a community of root systems to hold the bank in place while
providing a more natural habitat for wildlife. Returning the entire site back to its
original location will be possible if enough material is available on-site.
5. PROPOSED REPAIR PLAN
The repair option recommended by our design staff incorporates returning the
stream as close to its original location as possible and soil bioengineering practices
with in-stream flow modification structures and toe protection. Angular stone will be
required to be brought in from off-site to provide toe protection for right and left banks
and to be used in the installation of j-hook vanes. Local boulders from on-site will be
used as toe protection also. The section of the project reach upstream from original
bridge location has a wider floodplain, flatter channel slope and lower velocity than
the section of reach below original bridge location. By using boulders from on-site, it
will reduce the overall cost of the project. Another benefit of using on-site boulders is
the natural look it will give this stretch of stream. The recommended approach will
improve the overall success of the project by providing a sound repair design and by
protecting and enhancing the values of the site.
As shown on the attached proposed site plan and design details, we recommend that
in-stream structures be installed using angular rock along the left bank to deflect and
train flow back into original channel, toe protection using native and angular stone as
prescribed in the design details. Banks are to be sloped according to bank
stabilization details (2).
4
Streambank Stabilization (2)
Streambank Stabilization (2) will reshape the bank for the purpose of slope,
stabilization measures, and site topography. The slope should be graded no steeper
than 2 horizontal : 1 vertical and should be lined with a 100% coconut coir matting or
equivalent, staked on 3 foot centers and seeded with erosion control grass as site is
brought to finished grade.
Toe Stabilization
Toe stabilization will be required to protect streambanks from future scour and
piping. Native boulders and angular stone will be used from on-site for Stream
Stabilization (2) and angular. Toe protection measures will be lined with non-woven
geotextile fabric and backfilled with suitable material.
Buffer Planting
Riparian buffer will be planted along the repaired reach of streambank. The buffer
will be planted with native tree and shrub species and will provide stream channel
stability, surface water treatment, and wildlife habitat and food. Approved bare root
seedling species are provided in the repair plan and may be substituted by other
additional approved species and plant types (i.e. containerized, live stakes, and
transplants) if approved by designer. The majority of the planting will take place in
the fall to increase survivability. Tree species shall be planted on a 10 foot by 10 foot
spacing to ensure a desired planting density of 436 stems per acre. Shrub species
shall be planted on a 6 foot by 6 foot spacing to ensure a desired planting density of
1200 stems per acre. AES personnel will supervise the planting of permanent
vegetation. Temporary seeding measures will be applied to disturbed area to
stabilize site until permanent vegetation is established.
6. SPECIAL CONSIDERATIONS
Agricultural Pasture Land:
The Richlands site currently serves as pasture for horses. Horses have access to
both sides of the stream and there is currently no fencing keeping the horses out of
the stream. Upon completion of channel construction and buffer planting, the
disturbed site will be fenced to keep animals out of the site and out of the stream. By
moving the stream back to its original channel configuration, there will be a net
increase in pasture land when the site is stabilized.

Boulders of approximate dimension 2' x 3' x 4' shall be individually picked by
contractor from the quarry or on site for use in in-stream structures and toe protection.
Boulders smaller may be used, but they must be approved by engineer and may not
constitute more than 30% of the total boulders.
In-stream Structures
J-Hook Vanes and Toe Protection
A tracked hydraulic excavator with a thumb of sufficient size to move specified
boulders is required for this item. Precise placement of structures will be determined
during construction by the Engineer and may not reflect the construction by the
construction drawings. In-stream structures and toe stabilization must be inspected and
approved by the engineer. Excavation for the purpose of installation is incidental and is
covered by this line item.
The excavation of the subgrade and installation will be consecutive and
continuous. Once the installation procedure has been initiated, it will be completed
before the end of the workday. Any incidental/accidental discharge of sediment
accumulation as a result of the installation procedure will be removed or integrated into
the designed bedform. Excavation shall terminate at bedrock if contacted prior to the
9
design grade. Bedrock will be excavated only if it is determined to be rippable and
necessary by the engineer.
Install toe stabilization as shown on the Drawings and as directed by the Engineer.
Grade area where toe stabilization is to be constructed. Surface shall be free of
obstruction, debris, and pockets of soft or low density material. Unless otherwise
directed by the Engineer, the stone shall be placed on the slope and/or angle as indicated
on the plans. The stone shall be graded so that the smaller stones are uniformly
distributed throughout the mass. The Contractor may place the stone by mechanical
methods provided that when the work is completed, it forms a properly graded, dense,
neat layer of stone.
Place j-hook vane arms as shown on the Drawings. Footer rocks shall be installed
to define shape of in-stream rock structures. Footer rocks shall be installed such that their
long dimension is oriented in the direction of flow. No gaps shall be left between footer
rocks. Minimum footer rock depth below the proposed ground surface of the stream bed
shall be 4 feet. Rock sills shall extend a minimum of 3 feet beyond bankfull
(perpendicular to stream flow) as indicated on plans. Geotextile shall be placed over
structures and backfilled with aggregate as shown on plans.
Slope Protection
Grade area to be lined. Surface shall be free of obstructions, debris, and pockets of soft
or low density material. Final grade with topsoil shall be as shown on Drawings. Topsoil
shall be prepared with fertilizer and lime, and seeded as described in Temporary Seeding
section of Technical Specifications. Install coir matting as called out for in Drawings.
Stakes should be installed on 3' x 3' spacing. In the event that the matting is displaced or
damaged during installation, the matting shall be repositioned or replaced. This will be
done at no additional cost to the owner.
Permanent Vegetation
All plants shall be as called in these specifications and shown on the Drawings. All
plants delivered shall be true to name. Each plant, or group of the same species, variety,
and size of plant, shall be legibly tagged with the name and size of the plant. All plants
shall be first-class representatives of their species. Stakes shall be reasonably straight.
All plants shall be free from plant diseases and insect pests. All shipments of plants shall
comply with all nursery inspection and plant quarantine regulations of the States of origin
and destination, as well as with Federal regulations governing interstate movement of
stock. If stock from other States is used, the stock shall be accompanied by a tag or
certificate stating, in effect, that the stock has been inspected and certified by an
authorized official of the State of origin as apparently free from injurious plant pests.
All plants shall be subject to inspection at any time by the Engineer. Any such inspection
before or during planting operation, however shall not be construed as final acceptance of
the plants involved.
Bare root plants, if approved by the Engineer shall have a heavy fibrous root system
which has been developed by proper cultural treatment. They shall be dug, packaged,
10
transported, and handled in a manner that will prevent injury to or drying out of the
trunks, branches, or roots, or freezing of the roots.
Container grown plants, if approved by the Engineer shall be healthy, vigorous, well-
rooted and shall have become established in the container in which they are delivered.
These plants shall have been in the established container long enough for the fibrous
roots to have developed so that the root mass will retain its shape and hold together when
removed from the container. The container shall be a 3 gallon container or larger,
sufficiently rigid to firmly hold the soil protecting the root during transporting, handling,
and planting, and the soil shall not be allowed to become frozen.
Live stakes, if approved by the Engineer, shall consist of freshly cut live plants of select
stock which has been developed by proper cultural treatment. Stakes and cuttings shall
be 3/8" to ''/2" diameter and between 12 and 18 inches long. They shall be carefully cut
from mother-stock plantings. Plant materials shall be packaged, transported, and handled
in a manner that will prevent injury, drying out, or freezing.
No change in the specified plants (species, variety, size, caliper, furnish, etc) will be
made without written approval of the Engineer. All requests by the contractor for
substitutions shall be presented in writing and shall include a listing of the sources which
have been contacted in an attempt to secure the specified plant material. Requests for
substitutions shall include botanical name, common name, size, caliper, and furnish
description of the proposed substitute. No increase in compensation will be made to the
Contractor as a result of the use of the approved substitute plants.
In areas where permanent vegetation is directed, trees shall be planted on a 10' x 10'
spacing and shrub species planted on 6' x 6' spacing. A minimum of 5 tree species and 4
shrub species shall be chosen for planting from approved list. Areas to be planted with
only tree species or shrub species are called for in Drawings. The installation of bare root,
container grown plants, and live stakes shall be performed between October 15 and
October 31, 2005.

CONSTRUCTION SPECIFICATION
HERBACEOUS VEGETATION ESTABLISHMENT
1. SCOPE
The work shall consist of the preparation of a seedbed; furnishing, placing, and
covering limestone, fertilizer and seed; and other operations necessary for the
establishment of permanent grasses, forbs and legumes from seed on designated
areas.
2. LOCATION
The areas to be treated in accordance with these specifications shall be stream
banks, access areas, equipment staging areas and all areas disturbed by construction
activities.
3. MATERIALS
The kinds of limestone, the kinds and grades of fertilizer, and the kinds of seed
shall be as stated in Section 10 of this specification. No substitutions shall be made
without the approval of the Contracting Officer.
Delivery tickets showing amounts, kinds, and quality of materials will be furnished
to the Inspector or his designee prior to use of any of the materials.
4. MEASUREMENT OF AREAS AND COMPUTATION OF MATERIAL
QUANTITIES
Section 10 of this specification stipulates the surface area to be seeded. This area is
based on estimations of groups of individual sites and reaches. The actual areas
have not been measured. The actual surface area to be seeded should be expected
to differ from the estimates.
The contractor shall locate each site shown on the Site Location Maps and be
responsible for measuring the disturbed area to be seeded at each site. All sites
must be measured to determine seeding area. Acceptable methods of measurement
include, but are not limited to, surveyor's level or transit survey, measuring wheel,
measuring tape, compass and two-man mapper, GPS with minimum 5 meter
accuracy, and other electronic area mappers. Paced and estimated measurements
are not acceptable. The measurement method(s) used shall be approved by the
Inspector in advance of use. Areas shall be measured to an accuracy of plus or
minus 10 percent.
The contractor shall be responsible for computing and applying the specified
quantity of seeding and mulching materials based on the surface area measured.
Material quantities specified in Section 10 are minimums. Materials applied shall
be equal to or more than the minimum quantities calculated based on measured
areas for each site.
12
5. DOCUMENTATION OF ACTIVITIES
Surface area and material quantity computations shall be documented in a hard
cover bound field book with a minimum of 48 pages. Computations for each site
shall be documented on separate pages in the field book. The first five (5) pages of
each field book shall be reserved for a table of contents.
Each site shall be clearly designated with numbers corresponding to the site
number or reach number shown on the Site Location Maps. For individual sites
within a designated reach, a secondary letter or number shall be appended to the
reach number to uniquely designate the site.
For each site the method of measurement, the actual measurement dimensions and
computations, and the quantity of materials required shall be clearly documented.
A sketch of each site shall be included in the field book or reference made to a
specific sketch in a separate sketch notebook.
Any contact with landowners relative to seeding operations on their property shall
be promptly documented in the field book on pages dealing with the site in
question or referenced back to those pages. Other significant factors which impact
the area measured or the methods and effectiveness of seeding operations shall be
documented in the field book.
The contractor shall provide written verification in the field book for each site,
including signature and date, attesting that the documented materials have been '
applied in accordance with this specification. Field books shall be provided to the
Inspector with each request for payment. Field books and sketch notebooks shall
become the property of the Contracting Local Organization.
6.- COORDINATION OF OPERATIONS
A. Any question regarding seeding areas should be promptly brought to the
attention of the Contracting Officer or his designee.
B. The contractor shall adapt his operations to variations in weather or soil
conditions so as to expect the successful establishment and growth of grasses
and legumes.
In all operations covered by this specification, care shall be taken to preserve
the required final grades, and drainage of areas to be vegetated.
C. All materials, equipment, tools, and other items necessary to prepare a seedbed,
seed, and mulch for that day's operations shall be on the site before any
seedbed preparation is begun.
13
The work will be done in a manner so that within 24 hours no area on which
seed and/or fertilizer and lime have been applied is left without having mulch
applied. Any area left incomplete will be subject to reworking at the
contractor's expense if rain, wind, or other weather conditions materially
affect the quality of the work.
Herbaceous Vegetation Establishment for this project must be staged. Upon
completion of streambank stabilization activities, each completed work site
shall be seeded and mulched as specified before moving to the next
designated work site. The maximum area of disturbed soil per staging
interval is one (1) acre.
State Requirement - Maximum interval for ground cover on exposed slopes
is 15 working days or 30 calendar days following completion of any phase of
grading. Permanent ground cover for all disturbed areas must be completed
within 15 working days or 90 calendar days (whichever is shorter) following
completion of all construction activities.
Any completed areas disturbed by the contractor's operations on adjacent
areas shall be repaired or reworked to the satisfaction of the Contracting
Officer at the contractor's expense.
7. SEEDBED PREPARATION APPLYING AND COVERING LIMESTONE AND
FERTILIZER
Evenly distribute lime and fertilizer over the area and uniformly mix lime and
fertilizer into the top 3 inches of the soil with a small disc, spike-tooth harrow, or
other tillage equipment on all areas to be seeded where soils are predominantly
fined grained or sands. Where surface materials are predominantly gravels and/or
cobbles, no incorporation of lime and fertilizer is required.
Where a hydraulic seeder is used, application of the fertilizer and lime shall be
performed immediately prior to or during the site preparation operations and
applied with a hydraulic seeder.
8. APPLYING AND COVERING SEED
When a cyclone seeder is used, the area shall be cross seeded by applying one-half
the seed in one direction and the other half at right angles to the first direction. The
seed shall be covered to a depth of 1/2 inch by a garden rake, harrow, disk, or other
suitable implement where soils are predominantly fine grained or sands. Where
surface materials are predominantly gravels and/or cobbles, no incorporation of
seed is required.
Where a hydraulic seeder is used, the specified amount and analysis of materials
shall be mixed and applied with the hydraulic seeder. Application of wood
cellulose fiber will not be acceptable as a substitute for straw mulch. A suitable
tracer shall be used to clearly identify areas hydroseeded. A minimum of 500 lbs.
per acre of wood cellulose fiber or a non-toxic water base dye may be used as a
tracer. Seed shall not remain in water containing fertilizer more than 45 minutes
before being used.
9. MEASUREMENT AND PAYMENT
14
For items of work for which specific unit prices are established in the contract, the
area which has been acceptably vegetated will be measured to the nearest 1000
square feet. Payment for vegetation will be made at the contract unit price and
shall be considered full compensation for all labor, equipment, tools, materials, and
all other items necessary and incidental to the completion of the work.
Prior to final payment a ten (10) percent or greater random spot-check of seeded
sites will be conducted by the Contracting Local Organization. Field books and
sketch notebooks will be inspected for compliance with this specification. Sites
will be measured and inspected for proper quantity and application of seeding and
mulching materials. If spot-checks reveal that seeding has not been performed in
accordance with this specification, the contractor will be informed of the
discrepancies and shall immediately initiate corrective measures. Subsequent spot-
checks will be conducted by the Contracting Local Organization as required to
verify compliance with this specification. Payment will not be made until
inspections indicate that all sites have been measured and seeded in accordance
with this specification.
Compensation for any item of work described in the contract but not listed in the
bid schedule will be included in the payment for the item of work to which it is
made subsidiary. Such items and the items to which they are made subsidiary are
identified in Section 10 of this specification.

9. 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 site has experienced severe streambank erosion
channel relocation on site due to Hurricanes Frances and Ivan in September 2004. The
impacted areas threaten agricultural land and a private driveway. The channel has relocated
itself as a result of NC DOT bridge directing flow into the outside bend of the stream.
10. Describe the overall project in detail, including the type of equipment to be used:
The project reach includes approximately 300 feet of streambank stabilization and channel
relocation along Yadkin River located at 36° 05'7.74" N 81'35'51.54"W. Streambank repairs
Page 6 of 13
for this site include : (1) Returning channel as close as possible its original location (2)
Stabalizing streambanks, (3) installing in stream structures to protect streambanks
Returning the channel as close as possible its original location will require the old channel to be
excavated out to its original layout. This will be accomplished in the dry and the excavated
material will be stored between the old channel and new channel Upon completion of the
excavation and stabilization of the old channel, water from the new channel will be released back
into the old channel. The excavated fill material will then be placed into the new channel and
sloped according to streambank stabilization (2)
In stream i-hook vanes will be installed just downstream from NC DOT bridge to divert and train
the stream back as close as possible to its original channel A hydraulic excavator will be used to
remove cobble and place i-hook vane structures Whenever possible excavation equipment will
be kept out of the stream.
11. Explain the purpose of the proposed work:
The pumose of this protect is to relocate the stream back as close as possible to its original
channel and install i-hook vane structures to protect streambanks in danger of failure The
proposed repairs are not intended to enhance existing conditions or provide restoration using
natural channel design techniques Although some techniques to be used are also part of natural
channel design, such activities would require detailed engineering evaluation and design which is
beyond the scope of the EWP program

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. When possible equipment will
be kept out of the stream channel. When necessar for or equipment to be in channel care will be
taken that no fluid or other items including grease falls into the channel If a leak is detected
equipment will be removed from the stream and leak fixed or machine replaced When at all
possible stream material will be moved from dry areas to the banks this will minimize the
movement of wet stream material. Temporary and/or herbaceous vegetation shall be planted on
all bare soil within 15 days of ground disturbing activities Large rocky material will be brought
in to stabilize the toe of impacted river banks where necessary.
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 January 15, 2002, 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 NCEEP concurrence shall be placed on hold as incomplete.

Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federaUstate) land? Yes ® No ?
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ? No
3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ? No ?
Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ? No
Page I 1 of 13
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.
Zone* Impact Multiplier Required
(square feet) Mitieation
3 (2 for Catawba)
1.5
Total
* Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 213.0242 or.0244, or.0260.
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. Imperviousness will not change. Erosion and
sedimentation prevention and control will be maintained throughout this project rimarilX
through: proper water management construction sequencing, roper staging and stockpiling of
materials, and the maintenance at all times of suitable channel capacity for expected flow
events. Equipment fuels lubricants or other potential sources of water pollution will not be
stored in areas that could be flooded during this project
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Portable facilities shall be provided at the work site
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules?
Yes ? No
Is this an after-the-fact permit application? Yes ? No
XIV. Cumulative Impacts (required by DWQ)
Page 12 of 13
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ? No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
XV.
Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
