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
INSTREAM 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 bankfull 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 form 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 "arms" will be 2 — 4
percent The vane should extend from the bank and help identify the low flow
channel (See figure on the attached drawing)
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
USDA -NRCS page 1 of 6 Rock Structures
North Carolina August 1999
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.
8) INSTALLATION
USDA -NRCS page 2 of 6 Rock Structures
North Carolina August 1999
• Theengineenshall 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 theaengineer.
• 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.
10) FIGURES
Figures attached to this specification illustrate the placement and orientation of the various
instream rock structures which may be included in the plan. Figures are as follows

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,anchormg 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 iloosened and smoothed
Diskmg 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,iwplace
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 toibe seeded Uniformly mix lime and fertilizerinto 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 Ibs 4 -500 Ibs
Sod Mats
Stnp,and stockpile mats of existing desirable herbaceous vegetation Insure 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
Seed
TemporarylSeedmg - Use,whereuneeded 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

Permanent Seeding — Use in combination with woody plantings on the upslope side of the riparian
planting Spring planting time is ideal for native perennial warm season grasses These grasses,should be
used when enhancing wildlife habitat,is a goal of the riparian planting Spring planted'seed should be
treated with a cold wet chill process to maximize germination Fall plantings should be planted with a
lightly,sowed cool season annual to hold the soil and do not need'the wet chill process To improve wildlife
habitat existing stands of fescue can be killed using,an appropriate herbicide and warm season grasses can
be no -till planted into the sod Omit fertilizer when establishing native grasses, fertilizer can be applied the
second year to improve the stand

Mulching
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 15 tons per acre Apply mulch uniformly Anchor mulch
with a mulch crimper, asphalt tackifier or appropriate mulch netting
Streamside Woody Vegetation Establishment
This work consist of securing and planting permanent woody vegetation,usmg 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 orerosion 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 rowcrop site, reasonably free,of weeds, plantstock 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 1/2 inch below the, soil surface The,plantmg 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
