George Belflower stream stabilization project are attached. This project was funded through the
Environmental Quality Incentives Program (EQIP) along with other practices that will improve
environmental quality on this farm. Members of the NRCS Area 1 Engineering Staff completed
survey and design work, and will also supervise construction.
In addition to the EQIP project, this farmer has also been selected for funding through the
Agricultural Water Resources Assistance Program (AgWRAP) administered by the NC Soil &
Water Conservation Commission to construct a pond for agricultural water supply. This pond
will be located upstream of the proposed stream stabilization "Western Site". The local Soil and
Water Conservation District submitted a Farm Pond Exemption request, and the USACE
returned a "NO DEPARTMENT OF THE ARMY AUTHORIZATION REQUIRED" form
(Action ID: 2017-00255). This form is included in this application packet.
Please let me know if you have any questions or if we can do anything else.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The work consists of stabilizing and relocating the stream channel/banks on approximately 650' of stream. The majority of the work will be bank
shaping and in -stream rock or log structures. The proposed impacts will enhance the stream corridor providing increased aquatic and terrestrial
wildlife habitat and improved water quality.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
All graded areas will be seeded. The new streambanks will be protected by erosion control matting while vegetation is being established. Woody
plants (livestakes and/or rooted seedlings) will be a vital part of the final stabilization. Equipment will work in the dry from top of bank.

GENERAL PROJECT DESCRIPTION
George Belflower Farm
Stream Channel Restoration and Stabilization
Unnamed Tributary to Roberson Creek
Rutherford County, North Carolina
This stream restoration project will address streambank erosion on two separate unnamed
tributaries to Roberson Creek. Instabilities will be addressed on about 425 feet of one
stream and 221 feet of another for a total of 650 linear feet of proposed work.
The streams are labeled "Eastern Site" and "Western Site" on the plans.
The eastern stream channel has migrated laterally in multiple meander bends, likely due
to straightening and channelization in the past, an overly wide channel, and a high
width/depth ratio. This process is continuing to erode multiple vertical mass wasting
banks. Instabilities and an over -widened channel exist throughout most of the reach.
The western stream channel is severely incised and entrenched. Both banks are nearly
vertical throughout the majority of the existing reach. Very little floodplain exists at
bankfull elevation. The channel has migrated laterally in multiple meander bends, and
this process is continuing to erode multiple vertical mass wasting banks. Instabilities
exist throughout much of the reach.
The objective of this design is to address the dimension, pattern, and profile of each
stream to improve sediment transport and stop bank erosion. Pattern or alignment will be
corrected to a tolerable range and held in place with multiple structures including log
vanes, rock cross -vanes, and rock j -hooks. These structures will also maintain a stable
channel dimension and profile created through construction activities.
An agricultural water supply pond was planned and designed upstream of the proposed
stream restoration project by employees of the NC Division of Soil and Water
Conservation. The upstream face of the proposed dam will be on the upstream
landowner's property (son of Mr. Belflower), and the downstream face will be on Mr.
Belflower's property. The proposed stream restoration begins at the end of the designed
plunge pool, which serves as the outlet of the pond back into the stream. A Priority 1
restoration approach is proposed for the first 200 feet of the reach. Unfortunately,
property and topographic constraints prohibit continuing the Priority 1 restoration further
downstream. Therefore, the proposed channel will drop back into the existing channel
around Station 2+10. The remainder of the reach and all of the Eastern Site will correct
dimension, pattern, and profile at approximately the same elevations of the existing
stream.
Improved aquatic and terrestrial habitat will be a by-product of the stream stabilization.
Native herbaceous and woody vegetation will be installed to provide long term stability.
Landowner Guidance for Contracting Stream Projects
Certain issues can arise when contracting a stream stabilization project that normally do
not arise with more common construction contracts such as building construction or
earth moving projects. With most common projects, there is a high degree of certainty
that the project will be installed exactly as shown on the drawings and with the quantity
of materials estimated. This means that contractors can bid on the job with a fixed dollar
amount and should not be surprised by unforeseen changes, difficulties, or additional
materials required to complete the job properly. If a contract awarded at a fixed amount
encounters unforeseen issues during construction, problems with the contractor can
occur since these issues can cost the contractor large amounts of money which will
lower their profit margin.
While engineering plans are carefully prepared to show the expected extent of work,
stream stabilization projects are sometimes not installed exactly as shown on the plans.
Constructing stream projects is unique in that work is being done on a dynamic system
where previously unknown complications are commonly found only after construction
has begun. It is not uncommon during construction for the construction supervisor
(NRCS or SWCD personnel) to determine the need to deviate slightly from the
engineering plans. Other factors can impact the time it takes or the amount of materials
required to complete a project. A few examples follow:
• In -stream structure installation has a downstream effect causing a need for an
additional structure not shown in the plans, or making it possible to omit a
downstream structure
• Availability of suitable construction materials may necessitate a change of plans
• Equipment operator inexperience or equipment inadequacies can greatly
increase the time required to finish a project
• Stream bed properties such as previously unidentified bedrock seams or deep
unconsolidated stream bed material may decrease or increase required materials
• Large storm events and high flows that happen during construction can have
negative effects that must be repaired
All deviations from the plans affect the installation cost of the project making it either
more or less expensive. Material quantities, such as boulders for in -stream structures,
are very difficult to estimate accurately. The relative time required to complete a project
varies greatly from project to project. These factors make it difficult for both the
contractor and the engineer to predict the cost of installation. Also, there are only a
limited number of contractors that have experience with multiple stream projects so
many may underbid a project when bidding total cost. When the cost of installation turns
out to be more than a contractor expects, problems can occur especially if the contractor
is being paid a fixed amount for project completion.
For stream stabilization projects several hundred feet or more long and requiring multiple
in -stream structures, it is recommended that the landowner contract the job with
provisions to accommodate payment for changes to the plans or unexpected material
expenses. It can be problematic to try to work out costs for these issues once
construction is underway. There are various ways to set up your contract to avoid
problems during construction. Work with your contractor to come to good terms on how
to set up the contract so that unexpected issues can be easily resolved. And contact
your NRCS or SWCD representative for advice.

CONSTRUCTION SPECIFICATION
IN -STREAM STRUCTURES CONSTRUCTED OF ROCK
1) SCOPE
This specification covers the installation of Rock Vanes, J -Hooks, and Cross Vanes at locations
as shown on the construction plans and as directed by the engineer.
2) PURPOSE
• Redirect erosive velocities away from streambanks
• Provide aquatic habitat
• Cross Vanes may be used for grade control
3) DEFINITIONS
ROCK VANE - A deflective structure installed pointing upstream, beginning at bankf ill sloping
down to the streambed. The angle at which the vane points upstream from the
bank shall be 20-30 degrees. The slope of the top surface of the vane will be 5-7
percent. The vane should extend from the bank to approximately 1/3 of channel
width. (See fig. 1)
J -HOOK - A rock vane with a hooked portion on the streambed. The hook provides
additional habitat. (See fig. 2) May included a sill (See fig. 3) which continues
across the stream bed from the hook portion of the structure, perpendicular to
the flow and follows the shape and elevation of the stream bed and stream bank
up to interberm or as directed by the engineer.
CROSS VANE - A rock vane from both sides of the stream with a connecting bar on the
streambed. If this structure is used for grade control, the existing streambed
elevation may be increased by no more than 10 percent of bankfull, unless a
greater increase is provided for in the approved design. (See fig. 4)
WING
DEFLECTOR - A deflective structure installed with sloping "arms" the slope downward into the
stream bed. The angle the arms point downstream and upstream from the bank
is 20 — 30 degrees. The slope of the top surface of the downstream arm will be
2 — 4 percent. The vane should extend from the bank and help identify the low
flow channel. (See Construction Drawings - Engineer will direct construction)
USDA-NRCS page 1 of 6 Rock Structures
WEST Carolina August 1999
ENGINEER - The USDA-NRCS and/or SWCD person(s) who have appropriate construction
approval authority for Practice Standard 580, Streambank and Shoreline
Protection for the specific size and type of structure.
STREAMBANK — portions of intermittent or perennial streambanks which are eroding at an
accelerated rate due to the effects of stream flow near banks without adequate
vegetative cover and supporting riparian area.
BANKFULL — The stream flow level at which the stream channel is formed and maintained.
The term "bankfull" should not be confused with "the top of the bank". Persons
who have received training in Natural Stream Channel evaluation shall identify
the bankfull elevation.
THALWEG - The deepest part of the channel where the highest channel velocities occur.
4) PLANNING CONSIDERATIONS
This practice should be applied as a part of a total Natural Stream Channel Restoration design.
These structures are not intended to be a total solution to the streambank erosion problem in
themselves. They are to be used as a component of a total streambank management plan, which
may require a number of associated practices. In some cases modification of the stream
dimension, pattern and profile may be required before structures are installed. The use of rock
structures without considering the stable dimension, pattern, and profile of the stream will most
likely result in failure.
5) PERMITTING
No work, which is covered by this specification, shall be performed until the Army Corp of
Engineers has issued a Section 404 permit and the Division of Water Quality has issued a
Section 401 certification (if required). The final construction plans and specifications must be
prepared and approved prior to the beginning of construction.
6) EQUIPMENT
• A hydraulic excavator (trackhoe) with a hydraulic "thumb" shall be used to handle and install
the rocks
• All required safety equipment shall be available during construction. Safety equipment
includes but is not limited to hard hats, gloves, and eye and hearing protection.
7) SUPERVISION
The engineer must be on-site to supervise and inspect each operation as it is performed. No
work, which is covered by this specification, shall be performed in the absence of the engineer
except as approved by the engineer. The work shall be conducted as directed by the engineer.
The engineer shall be notified a minimum of 24 hours before installation is performed.
USDA-NRCS page 2 of 6 Rock Structures
WEST Carolina August 1999
8) INSTALLATION
• The engineer shall place a marker at the point where the last rock of the structure will meet
the streambed. This marker shall be set at a point, which represents the planned angle from
bankfull and the planned slope of the structure. The engineer should check to see if this point
is approximately 1/3 of the total channel width.
• Holes for footer rocks shall be excavated in the streambed at the location, elevation and
orientation as directed by the engineer.
• A footer rock of the size and shape as directed by the engineer shall be installed in the hole.
Multiple footer rocks may be required, at the discretion of the engineer or as provided for in
the approved plan.
• A structure rock of the size and shape as directed by the engineer shall be installed on top of
the footer rock.
• Streambed material will be removed as directed by the engineer if it is required to move the
thalweg of the stream to the point of the structure.
• Streambed material shall be placed on the upstream side of the structure near the bank.
• Equipment shall be operated from the streambank whenever possible.
• Equipment which appears to be leaking fluids shall be removed to a safe site away from the
stream corridor until it is repaired and confirmed that no leaks exist.
9) ASSOCIATED PRACTICES
• ROOT WADS and related instream structures planned as an integral component of the
natural stream channel restoration design.
• CRITICAL AREA SEEDING shall be applied on all disturbed areas.
• WOODY VEGETATION shall be established on the sloped bank above bankfull and on top
of the bank.
• RIPARIAN FOREST BUFFER should be considered.
• LIVESTOCK EXCLUSION shall be installed if livestock are pastured in the area.

CONSTRUCTION SPECIFICATION
LOG VANE
1) SCOPE
This specification covers the installation of Log Vane(s) at location(s) as shown on the
construction plans and as directed by the engineer.
2) PURPOSE
• Redirect erosive velocities away from streambanks
• Protect bank from erosion during the establishment of woody vegetation
• Provide aquatic and terrestrial habitat
• This practice does not apply to streams that are highly entrenched.
3) DEFINITIONS
LOG VANE — A log, installed at an angle of 20 to 30 degrees to the bank and at a slope of 5 to
7 percent from the streambank to the streambed. (See Fig 1)
ENGINEER - The USDA-NRCS and/or SWCD person(s) who have appropriate construction
approval authority for Practice Standard 580, Streambank and Shoreline
Protection for the specific size and type of structure.
STREAM BANK — Portions of intermittent or perennial stream banks which are eroding at an
accelerated rate due to the effects of stream flow near banks without adequate
vegetative cover and supporting riparian area.
BANKFULL (BKF) — The stream flow level at which the stream channel is formed and
maintained. The term "bankfull" should not be confused with "the top of the
bank". Persons who have received training in Natural Stream Channel
evaluation shall identify the bankfull elevation.
4) PLANNING CONSIDERATIONS
This practice should be applied as a part of a total Natural Stream Channel Restoration design.
Log Vanes are not intended to be a total solution to the streambank erosion problem by
themselves. They are to be used as a component of a total streambank management plan, which
may require a number of associated practices. In some cases modification of the stream
dimension, pattern and profile may be required before structures are installed. The use of log
vanes without considering the stable dimension, pattern, and profile of the stream will most
likely result in failure.
USDA-NRCS page 1 Log Vane
North Carolina October 2004
5) PERMITTING
No work, which is covered by this specification, shall be performed until the Army Corp of
Engineers has issued a Section 404 permit and the Division of Water Quality has issued a
Section 401 certification (if required). The final construction plans and specifications must be
prepared and approved prior to the beginning of construction.
6) EQUIPMENT
• A hydraulic excavator (trackhoe) with a hydraulic "thumb" shall be used to handle and install
log vanes
• A chain saw shall be available on site during construction
• All required safety equipment shall be available during construction. Safety equipment
includes but is not limited to hard hats, chain saw chaps, gloves, and eye and hearing
protection.
7) SUPERVISION
The engineer must be on-site to supervise and inspect each operation as it is performed. No
work, which is covered by this specification, shall be performed in the absence of the engineer
except as approved by the engineer. The work shall be conducted as directed by the engineer.
The engineer shall be notified a minimum of 24 hours before installation is performed.
8) INSTALLATION
Excavate a trench into the bank to embed one end of the log vane. The top of the log vane at the
point where it enters the bank should normally be at approximately the "inter -berm" elevation
(inter -berm is approximately one half the distance between water surface and bankfull).
Excavate a trench in the stream bed to embed the other end of the log vane ("Methods for
Securing Streambed End of Log", for additional information). Install the stump end of the log
in the trench on the bank. Any opening between the bottom of the log and the streambed shall be
closed by placing geotextile fabric filter cloth on the side of the log toward the bank. This filter
cloth should be nailed with large headed nails, such as roofing nails, to the side of the log. The
remaining filter cloth is to be draped down along side of the log and onto the bed of the stream.
Place streambed material back fill over the top of the filter cloth to a point sufficient to stop all
flow below the log. Note the process of installing the filter cloth and backfill is best done
concurrently. If an attempt is made to nail the filter cloth along the log for the entire length
before any backfill is placed, the filter cloth will tend to wash under the log.
METHODS FOR SECURING STREAMBED END OF LOG VANE
a) Place rocks (see Items of Work for Rock Size) on the end of the log to form a "J -Hook" and
to prevent the log from floating out of the streambed.
b) Install a vertical stake in the streambed on the downstream side of the log vane. The stake
should be at least six feet long and at least six inches in diameter at the smallest point.
Sharpen the stake on one end and drive it into the streambed with the equipment used to
place the log vane. Any stake remaining above the top of the log vane after driving, shall be
USDA-NRCS page 2 Log Vane
North Carolina October 2004
cut off to within approximately six inches of the top of the log vane. Connect the log vane
and stake with at least three turns of cable on each diagonal and cable clamps. The
connection should be similar to diagonal lashing.
c) Attach a cable to a Duckbill anchor (may use a double barrel crimp sleeve or two cable
clamps). Place the anchor on a drive rod. Install the anchor on the upstream side of the log
vane at a point which will allow the cable to be essentially perpendicular to the log at
approximately the mid -point of the portion of the log vane which is buried in the streambed.
Make three wraps of the cable around the Log Vane and secure the cable end with two cable
clamps (a self locking wire rope grip such as the "Gripple" or "Dyna-Tite" is highly
recommended). The cable MUST be pulled taunt to ensure proper anchorage.
All excavation will be performed at the location, elevation, and orientation and to the dimensions
as directed by the engineer.
The streambank shall be sloped to 1'/2:1 or flatter from the bankfull elevation to the top of the
bank unless otherwise directed by the Items of Work or the Engineer.
Equipment which appears to be leaking fluids shall be removed to a safe site away from the
stream corridor until it is repaired and confirmed that no leaks exist.
9) MATERIALS
• LENGTH OF THE LOG VANE — The stem shall be of sufficient length so that a minimum
of 8' is placed into well consolidated soil plus such length as is required to install the log on a
7% or less slope plus approximately 8' to bury into the streambed on the upstream end
• DIAMETER — The minimum diameter of the stem measured at smallest end shall be 6 inches
unless stated otherwise in the Items of Work.
• FORM — The stem shall be as straight as possible for the entire length. Log Vanes may not
have bows and/or other deformities which will cause a concentration of flow at any point
along the section of stem which is exposed to stream flow. The stem shall not exhibit an
unusual degree of taper. Forks are prohibited except within the portion which will be buried
in the streambed.
• SPECIES — Tree species shall be selected that exhibit rot resistance. Locust, White Oak, and
Black Walnut are some possible choices. Species such as Hemlock, Poplar, Maples,
Sycamore and White Pine have slight resistance to decay or are nonresistant to decay when
subjected to wet/dry cycles.
• HARVEST SITE — Trees shall not be harvested from within the riparian area except where
associated stream restoration activities require the removal of the tree. Trees which are
harvested from within the riparian area shall not be removed without the approval of the on-
site engineer. Trees which have already washed into the stream may be used if the on-site
engineer determines that they meet all criteria listed in this specification.
• QUALITY — Trees may be rejected by the on-site engineer if they are split, broken,
decaying, or otherwise exhibit faults which will cause the service life of the structure to be
less than the time required to establish permanent woody vegetation with sufficient root
systems to protect the streambank.

Streamside Herbaceous Vegetation Specifications
The work shall consist of preparing the area, furnishing and placing seed, sprigs, sod mats, mulch,
fertilizer, inoculate, soil amendments and anchoring mulch in the designated areas as specified; streambanks,
access areas, and other areas disturbed by construction activities.
Seedbed Preparation
On sites where equipment can be operated safely the seedbed shall be adequately loosened and smoothed.
Disking or cultipacking or both may be necessary. On sites where equipment cannot operate safely, the
seedbed shall be prepared by hand scarifying to provide a roughened surface so that seed will stay in place.
If seeding is done immediately following construction, seedbed preparation may not be required except on
compacted, polished or freshly cut areas.
Fertilizing
Evenly distribute lime and fertilizer over the area to be seeded. Uniformly mix lime and fertilizer into the
top 3 inches of the soil. Where surface materials are predominately gravel and/or cobble, no incorporation
is required. Apply lime and fertilizer according to soil test results or at the following rates.
Per 1000 sq. ft. Per Acre
Lime 50-100 lbs. 1-2 tons
10-10-10 Fertilizer 9-12 lbs. 4-500 lbs.
Sod Mats
Strip and stockpile mats of existing desirable herbaceous vegetation. Ensure that several inches of sod
remains attached to the vegetation. The root systems must remain moist while the vegetation is stockpiled.
Place the mats on the lower bank slopes and anchor in place.
Temporary Seeding - Use where needed for erosion and pollution control, when permanent vegetation cannot be
established due to planting season and where temporary ground cover is needed to allow native or woody vegetation
to become established.

Mulchinz
Mulching should be performed within 48 hours of seeding. Grain straw mulch should be applied on seeded
areas at a rate of 3 bales per 1000 square feet or 1.5 tons per acre. Apply mulch uniformly. Anchor
mulch with equipment traffic, mulch crimper, asphalt tackifier, or appropriate mulch netting.
Streamside Woody Vegetation Establishment
This work consist of securing and planting permanent woody vegetation using rooted stock, unrooted stock and
on site transplants.
Care and Handling
Planting stock should be stored in a cool moist environment or heeled in. Roots of bareroot stock shall be kept
moist during planting operations. Container or potted stock shall be kept moist at all times. The root balls of
transplanted stock must be kept moist.
Site Preparation
Desirable trees and shrubs on the construction site should be dug and stored. On recently graded sites use
temporary seedings, anchored mulch or erosion control fabrics to provide surface protection until woody
vegetation becomes established. Sod may be killed by non-selective herbicides the year previous to planting
stock (follow all federal, state and local regulations in the use of herbicides). When hand planting; scalp an area
at least 3 feet in diameter and 2-4 inches deep. Place plant in the center of the scalped area. On sites where
equipment cannot be operated safely and there are concerns about potential erosion use a non-selective herbicide
to kill vegetation in a 36 inch wide circle or 36 inch wide strip and plant in the center of the killed vegetation. If
the site is a row crop site, reasonably free of weeds, plant stock in the stubble without prior preparation. Sites
with undesirable brush will need initial treatments to facilitate planting and follow-up treatments to prevent
reencroachment.
Planting
Transplants should be replanted to the same depth they were originally growing. Plant rooted stock in a vertical
position with the root collar approximately % inch below the soil surface. The planting trench or hole must be
deep enough and wide enough to permit roots to spread out and down without J -rooting. Insert dormant cuttings
to the depth required to reach adequate soil moisture, leaving 2 to 3 buds above ground. After planting pack soil
around each plant firmly to remove air pockets.

A Priority 1 restoration approach connecting
the channel to the existing floodplain
elevation is proposed from Stations 0*00
to 2.1-00. Property and topographic
constraints require ending the Priority 1
restoration at Station 2+00 and shifting to
a Priority 3 approach until the end of the
project. A more detailed explanation is
offered in the specification package on the
page titled General Project Description.

Construction Notes
• Seed and mulch all disturbed areas as soon as possible according to the Streamside Herbaceous Vegetation
Specification - Temporary Seeding.
• Remove all exotic invasive species as directed by NRCS or SWCD staff.
• Protect all trees not required to be removed for construction purposes.
• Excavated and constructed benches and banks shall be revegetated according to the Streamside Herbaceous Vegetation
Specification - Temporary Seeding and Permanent Seeding, and the details shown in these drawings. Erosion control
matting shall be installed as well.
• Heavy equipment should work from the top of the bank whenever possible. Heavy equipment travel up and down the
stream corridor and across the stream should be kept to a minimum.
• Debris and construction waste shall be disposed of according to the recommendations of NRCS or SWCD staff.
• Thoroughly review all construction specifications prior to construction. Structure installation techniques and
specifics are not shown in detail in these drawings.
• All required permits and letters of consent from surrounding property owners must be obtained before
construction begins.
• No channel realignment or structure installation work shall take place without an NRCS representative present.
