SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY. REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE
ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PRESSURE ON THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING
CLEANOUT. REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE AREA TO GRADE AND STABILIZE IT AFTER THE
CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED.
CONSTRUCTION ENTRANCE
MAINTAIN GRAVEL PAD IN A CONDITION TO PREVENT MUD OR SEDIMENT FROM LEAVING THE CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC TOP DRESSING
WITH 2-INCH STONE. AFTER EACH RAINFALL, INSPECT ANY STRUCTURE USED TO TRAP SEDIMENT AND CLEAN IT OUT AS NECESSARY. IMMEDIATELY REMOVE ALL
OBJECTIONABLE MATERIALS SPILLED, WASHED, OR TRACKED ONTO PUBLIC ROADWAYS.

inlet protection should be provided to protect the storm drainage system and
downstream areas from sedimentation until permanent stabilization of the
disturbed drainage area.
Do not install this measure in an intermittent or perennial stream.
Planningproject stage
When construction on a ro'ect reaches a a where culverts and other storm
drainage structures are installed and many areas are brought to the desired
Considerations grade, there is a need to protect the points where runoff can leave the site
through culverts or storm drains. Similar to drop and curb inlets, culverts
receiving runoff from disturbed areas can convey large amounts of sediment
to lakes or streams. Even if the pipe discharges into a sediment trap or basin
PPP
the pipe or pipe system itself may clog with sediment.
Design Criteria When used in combination with an excavated sediment storage area to serve
as a temporary sediment trap, the design criteria for temporary sediment traps
must be satisfied. The maximum drainage area should be 5 acres, and 3600
cubic feet of sediment storage per acre of disturbed drainage area should be
provided.
The minimum stone height should be 2 feet, with side slopes no steeper than
2:1. The stone "horseshoe" around the pipe inlet should be constructed of
Class B or Class I riprap, with a minimum crest width of 3 feet. The outside
face of the riprap should be coved with a 12-inch thick layer of #5 or #57
washed stone.
In preparing plans for rock pipe inlet protection, it is important to protect the
embankment over the pipe from overtopping. The top of the stone should be a
minimum of 1 foot below the to of the fill over the pipe. The stone should tie
P PP
into the fill on both sides of the pipe. The inside toe of the stone should be no
closer than 2 feet from the culvert opening to allow passage of high flows.
The sediment storage area should be excavated upstream of the rock pipe inlet
protection, with a minimum depth of 18 inches below grade.
0
WashingIf conditions at the site are such that most of the mud and sediment
are not removed by vehicles traveling over the gravel, the tires should be
washed. Washing should be done on an area stabilized with crushed stone
that drains into a sediment trap or other suitable disposal area. A wash rack
may also be used to make washing more convenient and effective.
Construction 1, Clear the entrance and exit area of all vegetation, roots, and other
objectionable material and properly grade it.
Specifications
2. Place the gravel to the specific grade and dimensions shown on the plans,
and smooth it.
3. Provide drainage to carry water to a sediment trap or other suitable
outlet.
4. Use geotextile fabrics because they improve stability of the foundation in
locations subject to seepage or high water table.
Maintenance Maintain the gravel pad in a condition to prevent mud or sediment from
leaving the construction site. This may require periodic topdressing with 2-
inch stone. After each rainfall, inspect any structure used to trap sediment
and clean it out as necessary. Immediately remove all objectionable materials
spilled, washed, or tracked onto public roadways.

Definition A temporary measure of wire -mesh hardware cloth around steel posts
supporting washed stone placed around the opening of a drop inlet.
Purpose To prevent sediment from entering yard inlets, grated storm drains or drop
inlets during construction. This practice allows early use of the storm drain
system.
Conditions Where To be placed around a catch basin or a drop inlet and where the flow is light to
moderate. If heavy flow is anticipated, use the rock doughnut inlet protection
Practice Applies method (Practice 6.54, Rock Doughnut Inlet Protection). it is also used where
storm drain inlets are to be made operational before permanent stabilization
of the disturbed drainage area. This method of inlet protection is effective
where the inlet is expected to drain shallow sheet flow. The immediate [and
area around the inlet should be relatively flat (less than 1 percent) and located
so that accumulated sediment can be easily removed.
This practice must not be used near the edge of fill material and must not
divert water over cut or fill slopes.
Design Criteria Ensure that drainage areas do not exceed 1 acre per inlet.
For securing the wire mesh hardware cloth barriers, use steel T posts. The posts
need to be 1.25 lb/linear ft steel with a minimum length of 5 feet. Make sure
the posts have projections to facilitate fastening the hardware cloth. Securely
drive each stake into the ground to a minimum depth of 2 feet. The maximum
spacing for the posts is 4 feet.
The wire mesh should be at least a 19-gauge hardware cloth with a '/4 inch
mesh opening. The total height should be a minimum of 2 feet. Providing a
flap of hardware cloth on the ground projecting away from the inlet can aid in
removal of the stone at the project's completion. The sediment control stone,
with a height of 16 inches, should have a outside slope of 2:1.
The top elevation of the structure must be at least 12 inches lower than the
ground elevation downslope from the inlet. It is important that all storm
flows pass over the structure into the storm drain and not bypass the structure.
Temporary dikes below the structure may be necessary to prevent bypass flow.
Soil excavated when constructing the sediment pool may be used for this
purpose (Figure 6.51a).

2. Install the Class B or Class I riprap in a semi -circle around the pipe
inlet. The stone should be built up higher on each end where it ties into the
embankment. The minimum crest width of the riprap should be 3 feet, with a
minimum bottom width of I 1 feet. The minimum height should be 2 feet, but
also 1 foot lower than the shoulder of the embankment or diversions.
3. A 1 foot thick layer of NC DOT #5 or #57 stone should be placed on the
outside slope of the riprap.
4. The sediment storage area should be excavated around the outside of the
stone horseshoe 18 inches below natural grade.
5. When the contributing drainage area has been stabilized, fill depression
and establish final grading elevations, compact area properly, and stabilize
with ground cover.
Maintenance Inspect rock pipe inlet protection at least weekly and after each significant (%z
inch or greater) rainfall event and repair immediately. Remove sediment and
restore the sediment storage area to its original dimensions when the sediment
has accumulated to one-half the design depth of the trap. Place the sediment
that is removed in the designated disposal area and replace the contaminated
part of the gravel facing.
Check the structure for damage. Any riprap displaced from the stone horseshoe
must be replaced immediately.
After all the sediment -producing areas have been permanently stabilized
P g P Y
remove the structure and all the unstable sediment. Smooth the area to
blend with the adjoining areas and provide permanent ground cover (Surface

Temporary seeding controls runoff and erosion until permanent vegetation or

residue for soil protection and seedbed preparation, and reduces problems of
mud and dust production from bare soil surfaces during construction.

vegetative cover is needed for less than 1 year. Applications of this practice
include diversions, dams, temporary sediment basins, temporary road banks,
and topsoil stockpiles.
P I a n n i n g
Annual plants, which sprout and grow rapidly and survive for only one season,
Considerations
are suitable for establishing initial or temporary vegetative cover. Temporary
seeding preserves the integrity of earthen sediment control structures such
as dikes, diversions, and the banks of dams and sediment basins. It can also
reduce the amount of maintenance associated with these devices. For example,
the frequency of sediment basin cleanouts will be reduced if watershed areas,
outside the active construction zone, are stabilized.
Proper seedbed preparation, selection ofappropriate species, and use of quality
seed are as important in this Practice as in Practice 6.11, Permanent Seeding.
Failure to follow established guidelines and recommendations carefully may
result in an inadequate or short-lived stand of vegetation that will not control
erosion.
Temporary seeding provides protection for no more than I year, during which
time permanent stabilization should be initiated.
Specifications
Complete grading before preparing seedbeds, and install all necessary erosion
control practices such as, dikes, waterways, and basins. Minimize steep slopes
because they make seedbed preparation difficult and increase the erosion
hazard. If soils become compacted during grading, loosen them to a depth of
6-8 inches using a ripper, harrow, or chisel plow.
SEEDBED PREPARATION
Good seedbed preparation is essential to successful plant establishment. A
good seedbed is well -pulverized, loose, and uniform. Where hydroseeding
methods are used, the surface may be left with a more irregular surface of
large clods and stones.
Liming -Apply lime according to soil test recommendations. Ifthe pH (acidity)
of the soil is not known, an application of ground agricultural limestone at the

rate of 1 to 1 1/2 tons/acre on coarse -textured soils and 2-3 tons/acre on fine -
textured soils is usually sufficient. Apply limestone uniformly and incorporate
into the to 4-6 inches of soil. Soils with a H of 6 or higher need not be
P P g
limed.
Fertilizer -Base application rates on soil tests. When these are not possible,
apply a 10-10-10 grade fertilizer at 700-1,000 lb/acre. Both fertilizer and lime
should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is
used do not mix seed and fertilizer more than 30 minutes before application.
Surface rots hening- If recent tillage operations erations have resulted in a loose
g g
surface, additional roughening may not be required, except to break up large
clods. If rainfall causes the surface to become sealed or crusted, loosen it
just prior to seeding b disking, raking, harrowing, or other suitable methods.
J P g Y gm g, g,
Groove or furrow slopes steeper than 3:1 on the contour before seeding
(Practice 6.03, Surface Roughening).
PLANT SELECTION
Select an appropriate species or species mixture from Table 6.1OR for seeding
in late winter and early spring, Table 6.1Ob for summer, and Table 6.1Oc for
fall.
In the Mountains, December and January seedings have poor chances of
success. When it is necessary to plant at these times, use recommendations
for fall and a securely tacked mulch.
SEEDING
Evenly apply seed using a cyclone seeder (broadcast), drill, cultipacker seeder,
or hY droseeder. Use seedingrates given in Tables 6.10a-6.10c. Broadcast
seeding and hydroseeding are appropriate for steep slopes where equipment
cannot be driven. Hand broadcasting is not recommended because of the
difficulty in achieving a uniform distribution.
Small grains should be planted no more than 1 inch deep, and grasses and
legumes no more than 1/2 inch. Broadcast seed must be covered by raking
or chain dragging, and then lightly firmed with a roller or cultipacker.
Hydroseeded mixtures should include a wood fiber (cellulose) mulch.
MULCHING
The use of an appropriate mulch will help ensure establishment under normal
conditions, and is essential to seeding success under harsh site conditions
(Practice 6.14, Mulching). Harsh site conditions include:
• seeding in fall for winter cover (wood fiber mulches are not considered
adequate for this use),
• slopes steeper than 3:1,
• excessively hot or dry weather,
• adverse soils (shallow, rocky, or high in clay or sand), and
• areas receiving concentrated flow.
If the area to be mulched is subject to concentrated waterflow, as in channels,
anchor mulch with netting (Practice 6.14, Mulching).
Practice Standards and Specifications
Maintenance Reseed and mulch areas where seedling emergence is poor, or where erosion
occurs, as soon as possible. Do not mow. Protect from traffic as much as
Possible.

6.62
Definition A temporary sediment control measure consisting of fabric buried at the
bottom, stretched, and supported by posts.
Purpose To retain sediment from small disturbed areas by reducing the velocity of
sheet flows to allow sediment deposition.
Conditions Where Below small -disturbed areas that are less then'/4 acre per 100 feet of fence.
Practice Applies Where runoff can be stored behind the sediment fence without damaging the
fence or the submerged area behind the fence.
Do not install sediment fences across streams, ditches, or waterways, or
other areas of concentrated flow.
Sediment fence should be placed along topographic elevation contours, where
it can intercept stormwater runoff that is in dispersed sheet flow. Sediment
fence should not be used alone below graded slopes greater than 10 feet in
height.
Planning A sediment fence is a system to retain sediment on the construction site. The
fence retains sedimentprimarily retardingfl w anri promoting depos
ition.
operation, generally the fence becomes clogged with fine particles, which
reduce the flow rate. This causes a pond to develop behind the fence. The
designer should anticipate ponding and provide sufficient storage areas and
overflow outlets to prevent flows from overtopping the fence. Since sediment
fences are not designed to withstand high water levels, locate them so that
only shallow pools can form. Tie the ends of a sediment fence into higher
ground to prevent flow around the end of the fence before the pool reaches
design level. Curling each end of the fence uphill in a "J" pattern may be
appropriate to prevent end flow. Provide stabilized outlets to protect the fence
system and release storm flows that exceed the design stone.
Deposition occurs as the storage pool forms behind the fence. The designer can
direct flows to specified deposition areas through appropriate positioning of
the fence or by providing an excavated area behind the fence. Plan deposition
areas at accessible points to promote routine cleanout and maintenance. Show
deposition areas in the erosion and sedimentation control plan. A sediment
fence acts as a diversion if placed slightly off the contour. A maximum slope
of 2 percent is recommended. This technique may be used to control shallow,
uniform flows from small disturbed areas and to deliver sediment -laden water
to deposition areas. The anchoring of the toe of the fence should be reinforced
with 12 inches of NC DOT #5 or #57 washed stone when flow will run parallel
to the toe of the fence.
Sediment fences serve no function along ridges or near drainage divides where
there is little movement of water. Confining or diverting runoff unnecessarily
with a sediment fence may create erosion and sedimentation problems that
would not otherwise occur.

during the soil preparation process, add pH modifier and fertilizers at the
rate specified in the soil test report.
• Re -compact the area utilizing a cultipacker roller. The finished grade shall
be a smooth even soil surface with a loose uniformly fine texture. All
ridges and depressions shah be removed and fined to provide the approved

surface drainage. Seeding of graded areas is to be done immediately after
finished grades are obtained and seedbed preparation is completed.
Areas to be Sprigged, Sodded, and/or Planted:
• At the time of planting till or disc the prepared areas to a depth of four (4)
to six (6) inches below the approved finished grade. Remove all stones
larger than three (3) inches on any side, sticks, roots and other extraneous
materials that surface. If not incorporated in the ripping process, add pH
modifier, fertilizer, and other recommended soil amendments.
• Re -compact the area utilizing a cultipacker roller and prepare final grades
as described above. Install sprigs, sod and plants as directed immediately
after fine grading is complete. Mulch, mat and/or tack as specified.
VEGETATION
Availability of seed and plant materials is an important consideration of
any construction stabilization effort. Throughout North Carolina, climate,
economics, construction schedule delays and accelerations, and other factors
present difficult challenges in specifying the different vegetation needed for
site stabilization. To help resolve this issue, vegetative stabilization requires
consideration in three categories:
is Immediate Stabilization -nurse crop varieties (Note: temporary mulching
may be utilized for immediate stabilization if outlined on the approved
my
plans and construction sequence.)
■ Primary Stabilization - plant varieties providing cover up to 3 years with
a specified maintenance program
■ Long Term Stabilization - plant varieties providing protective cover with
maintenance levels selected by the owner
An adequate job in one of these areas does not guarantee success in the later
phases. Horticultural maintenance must be included in the plans.
Immediate vegetative cover will always require additional fertilization, soil
amendments, soil tests, overseeding and/or other horticultural maintenance
until primary vegetative cover is established.
a
Straw barriers have only a 0-20% trapping efficiency and are inadequate. Straw
bales may not be used in place of sediment fence. Prefabricated sediment fence
with the fabric already stapled to thin wooden posts does not meet minimum
standards specified later in this section.
Anchoring of sediment fence is critical. The toe of the fabric must be anchored
in a trench backfilled with compacted earth. Mechanical compaction must be
provided in order for the fence to effectively pond runoff.
Design Criteria Ensure that drainage area is no greater than'/4 acre per 100 feet offence. This
is the maximum drainage area when the sloe is less than 2 percent. Where
P
all runoff is to be stored behind the fence, ensure that the maximum slope
length behind a sediment fence does not exceed the specifications shown in
Table 6.62a. The shorter slope length allowed for steeper slopes will greatly
reduce the maximum drainage area. For example, a 10-20 % slope may have
a maximum slope length of 25 feet. For a 100-foot length of sediment fence,
the drainage area would be 25ft X 100ft = 2500sq.ft., or 0.06 acres.

Make the fence stable for the 10-year peak storm runoff.
Ensure that the depth of impounded water does not exceed 1.5 feet at any point
along the fence.
If non -erosive outlets are provided, slope length may be increased beyond
that shown in Table 6.62a, but runoff from the area should be determined and
bypass capacity and erosion potential aloe the fence must be checked. The
YP P tY P g
velocity of the flow at the outlet or along the fence should be in keeping with
Table 8.05d, Appendix 8.05.
Provide a rira splash ad or other outlet protection device for an point

where flow may overtop the sediment fence, such as natural depressions or
swales. Ensure that the maximum height of the fence at a protected, reinforced
outlet does not exceed 2 feet and that support post spacing does not exceed 4
feet.
The design life of a synthetic sediment fence should be 6 months.
Construction MATERIALS
Specifications 1. Use a synthetic filter fabric of at least 95% by weight of polyolefins or
Polyester, which is certified by the manufacturer or supplier as conforming to
the requirements in ASTM D 6461, which is shown in part in Table 6.62b.
Synthetic filter fabric should contain ultraviolet ray inhibitors and stabilizers
to provide a minimum of 6 months of expected usable construction life at a
temperature range of 0 to 120' F.
Practice Standards and Specifications
2. Ensure that posts for sediment fences are 1.25 lb/linear ft minimum
steel with a minimum length of 5 feet. Make sure that steel posts have
projections to facilitate fastening the fabric.
3. For reinforcement of standard strength filter fabric, use wire fence with a
minimum 14 gauge and a maximum mesh spacing of 6 inches.

CONSTRUCTION
1. Construct the sediment barrier of standard strength or extra strength
synthetic filter fabrics.
2. Ensure that the height of the sediment fence does not exceed 24 inches
above the ground surface. (Higher fences may impound volumes of water
sufficient to cause failure of the structure.)
3. Construct the filter fabric from a continuous roll cut to the length of the
barrier to avoid joints. When joints are necessary, securely fasten the filter
cloth only at a support post with 4 feet minimum overlap to the next post.
4. Support standard strength filter fabric by wire mesh fastened securely to
the upslope side of the posts. Extend the wire mesh support to the bottom of
the trench. Fasten the wire reinforcement then fabric on the upslope side of
the fence post. Wire or plastic zip ties should have minimum 50 pound tensile
strength.
5. When a wire mesh support fence is used, space posts a maximum of 8 feet
apart. Support posts should be driven securely into the ground a minimum of
24 inches.
6. Extra strength filter fabric with 6 feet post spacing does not require wire
mesh support fence. Securely fasten the filter fabric directly to posts. Wire or
plastic zip ties should have minimum 50 pound tensile strength.
0
7. Excavate a trench approximately 4 inches wide and 8 inches deep along
the proposed line of posts and upslope from the barrier (Figure 6.62a).
8. Place 12 inches of the fabric along the bottom and side of the trench.
9. Backfill the trench with soil placed over the filter fabric and compact.
Thorough compaction of the backfill is critical to silt fence performance.
10. Do not attach filter fabric to existing trees.
SEDIMENT FENCE INSTALLATION USING THE SLICING METHOD
Instead of excavatinga trench placing fabric and then backfillin trench
,P g g ,
sediment fence may be installed using specially designed equipment that
inserts the fabric into a cut sliced in the ground with a disc (Figure 6.62b).
Installation 1. The base of both end posts should be at least one foot higher than the
middle of the fence. Check with a level if necessary.
Specifications
2. Install posts 4 feet apart in critical areas and 6 feet apart on standard
applications.
3. Install posts 2 feet deep on the downstream side of the silt fence, and
as close as possible to the fabric, enabling posts to support the fabric from
upstream water pressure.
4. Install posts with the nipples facing away from the silt fabric.
5. Attach the fabric to each post with three ties, all spaced within the top 8
inches of the fabric. Attach each tie diagonally 45 degrees through the fabric
with each puncture at least 1 inch vertically apart. Also, each tie should be
positioned to hang on a post nipple when tightened to prevent sagging.
6. Wrap approximately 6 inches of fabric around the end posts and secure
with 3 ties.
7. No more than 24 inches of a 36 inch fabric is allowed above ground
level.
8. The installation should be checked and corrected for any deviations before
compaction.
9. Compaction is vitally important for effective results. Compact the soil
immediately next to the silt fence fabric with the front wheel of the tractor,
skid steer, or roller exerting at least 60 pounds per square inch. Compact the
upstream side first, and then each side twice for a total of 4 trips.

acceptable as an end use would be lawns in residential and commercial
developments that are established, monitored and complimented with regular
and approved horticultural maintenance practices. (See Example 6.1 La.)
In projects where continual maintenance will not be provided or scheduled
following the primary stabilization of a project, long-term stabilization will
be necessary. Maintenance of initial and long -tern stabilization can cease
only after the long-term cover has established and hardened to local climatic
conditions. Maintenance of long-term. vegetation must be included in the
project construction sequence and on the approved plan. Examples of
areas suitable for long term vegetation include roadsides, reforestation areas,
restored flood plains, restored riparian areas, phased closing of landfills, and
mining reclamation.
Complete stabilization requires using at least two, and most times, all three
vegetative phases. The design professional must clearly communicate this point
in their specifications, construction sequence, and in direct communications
to owners and installers. The charts in tables 6.1 La through 6.1 Ld provide
information to assist the design professional in this task. The tables are not
inclusive and are presented only as alternatives. The professional is expected
and required to provide design and specifications that combine the information
in the manual with knowledge of the particular sites and their constraints.
pH AND NUTRIENT AMENDMENTS
Determining the nutrients that enable seed and container plants to grow,
flourish, and become established after planting are critical elements of the
design and stabilization process. The soils tests previously described will
provide a recipe for amendments based on particular plants and particular
soils. The test results will recommend the amounts of base elements (nitrogen,
phosphorous, potassium), pH modifiers and other trace elements that should to
be added to the soil for selected species of seeds and plants.
The acid/base characteristic of the soil is a primary component of soil fertility.
If the soil acidity is not in the proper range, other nutrients will be ineffective,
resulting in less productive plant growth. Most plants grow best in a pH range
of 6.5 - 7.0 (slightly acidic to neutral). The soil tests will recommend the
specific amendments and application rates required to achieve this range.
These amendments must be incorporated into the soil (not applied on the
surface) to be effective. (See the General Requirements for soil preparation
specifications and timing for incorporation of soil amendments.)
The base elements are easily found in bulk quantities. Lime can also be
obtained in large quantities. They all must be thoroughly incorporated into
the soil through appropriate mechanical means. Ground surface applications
without proper soil mixing will result in poor results.
In addition to the base fertilizers, other trace elements are needed to produce
healthy and vigorous growth. These include but may not be limited to sulfur,
manganese, zinc, boron, chlorine and molybdenum. If not already included
with bulk mixes of the base elements, they can be obtained from commercial
suppliers.
Provisions for soils test during and/or after initial grading is complete shall
be included on the approved plan, in the approved construction sequence, and

Some common examples of starter type fertilizers required for a 1,000 sq.

of 18-24-6. For sandy soils, typical to coastal plain and sandhills of North
Carolina, fertilizer rates should be increased by 20 percent.
Where available, it is recommended that the design professional specify
organic compounds that meet the fertilization requirements, pH and other
element requirements. Initial studies have indicated that these compounds
have a more positive effect on the environment than some of the synthetic
compounds used to manufacture inorganic fertilizers. These materials are
readily available in the commercial trade as well as found in recycled yard
waste debris, sewerage sludge, lime -stabilized sludge and animal manures.
Materials proposed for use must be industry certified and/or privately tested
and certified to be acceptable for proposed areas of use and application prior
to approval.
MULCHES AND TACKING AGENTS
Mulches and tacking agents may be required or necessary to protect a seedbed's
disturbed surface until the seed can germinate and provide the required
protection from erosion. Selection of the materials used in this application
should be based on their ability to hold moisture in the soil, as well as protect
exposed soil from rainfall, stone water runoff, and wind. The availability of
the selected material and the mean to apply it are critical factors to consider
when planning for the stabilization of any disturbed area. The mulch must
cover a minimum of eighty (80) percent of the soil surface and must be secured
by a tacking agent, crimping, or protective biodegradable netting. Netting that
incorporates plastic mesh and/or plastic twine should not be used in wetlands,
riparian buffers or floodplains due to the potential of small animal mortality.
See Section 6.14 for detailed specifications and product applications.
SOIL BLANKETS
Soil blankets can be an acceptable and effective method of temporary sediment
and erosion control in lieu of nurse crops. See Section 6.17 of the manual for
descriptions of this product and how it can be used in conjunction with this
section. In absence of mulches and tracking agents other means of protection
may be necessary and required.

Permanent native seed species within the seed mixture should be selected
based on natural occurrence of each species in the project site area. Climate,
soils, topography, and aspect are major factors affecting the suitability of plants
for a particular site and these factors vary widely across North Carolina, with
the most significant contrasts occurring among the three major physiographic
regions of the state - Mountains, Piedmont, and Coastal Plain. Sub -regions
of the state should also be considered. For example, the Triassic Basin in the
Piedmont region may have characteristics that call for special soil treatment,
limited plant selection, and special maintenance. Even within the riparian
area there may be need for different species depending on site conditions
Y P P g
i.e. sand alluvial flood lain with wet pockets). Therefore thoughtful
( , dii' Y P P ) g
planning is required when selecting species for individual sites in order to
maximize successful vegetation establishment.
Native seed and plant species are included on the plant list in Appendix 8.02
of this manual.
The design professional should note that regardless of the benefits and
advantages of native seeds and plants, there are potential issues if proper
planning, installation and maintenance do not occur. These may include:
• Potential for erosion or washout during the establishment stage;
• Seasonal limitation on suitable seeding dates and availability of seed and
plants;
• Adaptability of species at specific sites;
• Availability of water and appropriate temperatures during germination
and early growth; and
• Lack of maintenance to control invasive plants and undesirable
competition.
PLANTING
• Seed - Prepare the seed bed as described above in soil preparation. Apply
seed at rates specified on the plans, and/or as recommended in Tables
6.11a-c of this manual, with a cyclone seeder, prop type spreader, drill,
or hydroseeder on and/or into the prepared bed. Incorporate the seed
into the seed bed as specified. Provide finished grades as specified on
the approved plan and carefully culti-pack the seedbed as terrain allows.
If terrain does not allow for the use of a cultipacker, the approved plans
and construction sequence must provide an alternative method of lightly
compacting the soil. Mulch immediately.
• Sprigs and Sod -Install onto the prepared seedbed per the most current
guidance in Carolina Lawns, NCSU Extension BulletinAG-69, or Practice
6.12 Sodding.

Practice Standards and Specifications
Soil tests will indicate the texture of the given soil but will not
provide recommendations for amendments that will improve the soil
texture. Generally, the addition of organic materials will improve the
porosity of heavy clay soils and improve the water holding capacity of
extremely sandy soils. On sites where these different soil conditions
exist, it is recommended that a design professional with experience in
soil modification be employed to recommend the proper amendments.
For more information visit the NCDA Agronomic Services Soil Testing web
page http://www.agr.state.nc.us/agronomic/sthome.htrn
SOIL PREPARATION
Proper soil preparation is necessary for successful seed germination and root
establishment. It is also necessaryfor establishment of rooted sprigs, sod and
woody plants. Heavily compacted soils prevent air, nutrients and moisture
from reaching roots thereby retarding or preventing plant growth. The success
of site stabilization and reduction of future maintenance are dependent on an
adequately prepared soil bed. Following are the requirements for preparation
of areas to be vegetated by 1sing, sprigging, sodding, and/or planting of
woody plants:
General Requirements:
• Preparation for primary/permanent stabilization shall not begin until all
construction and utilitywork within the preparation area is complete.
P P P
However, it may be necessary to prepare for nurse crops prior to
completion of construction and installation of utilities.
• A North Carolina Department of Agriculture Soils Test or equal) P g ( q ) shall
be obtained for all areas to be seeded, sprigged, sodded or planted.
Recommended fertilizer and pH adjusting products shall be incorporated
into the prepared areas and backfill material per the test.
• All areas to be seeded or planted shall be tilled or ripped to a depth specified
on the approved plans, construction sequence and/or construction bid
list Rinnina r cicfs of ire l fismrres in -ft- o
P-Tthe entire surface area, utilizing an implement that will not glaze the side
walls of the fissures. Site preparation that does not comply with these
documents shall not be acceptable. The depth of soil preparation may
be established as a range based on the approval of the reviewing state or
local agency. Once tilled or ripped according to the approved plan, all
areas are to be returned to the approved final grade. pH modifiers and/or
other soil amendments specified in the soil tests can be added during the
P g
soil preparation procedure or as described below.
• All stones larger than three (3) inches on any side, sticks, roots, and other
extraneous materials that surface during the bed preparation shall be
removed.

NOTE:
With the native varieties, the seed mix should be in the range of 15 pounds per acre.
Depending on availability of native seeds adaptable to North Carolina, the percentage
of a particular variety used may be reduced or increased accordingly. Although
diversity is desirable, it is imperative that the primary crop develop and become an
effective protective cover. In addition to the native species mix, additional nurse crop
species must be included to provide immediate stabilization and an adequate ground cover.
