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 sediment primarily by retarding flow and promoting deposition.
Considerations In 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 storm.
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 fimction 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.

6.62.5
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 1/4 acre per 100 feet offence. This
is the maximum drainage area when the slope is less than 2 percent. Where
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 along the fence must be checked. The
velocity of the flow at the outlet or along the fence should be in keeping with
Table 8.05d, Appendix 8.05.
Provide a riprap splash pad or other outlet protection device for any 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
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.
6.62.3
Practice Standards and Specifications
Maintenance Inspect sediment fences at least once a week and after each rainfall. Make any
required repairs immediately.
Should the fabric of a 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.

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 excavating a trench, placing fabric and then backfilling trench,
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.

Washing —If 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 I. Clear the entrance and exit area of all vegetation, roots, and other
Specifications objectionable material and properly grade it.
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.

Purpose To preserve and protect trees that have present or future value for their use in
protection from erosion, for their landscape and aesthetic value, or for other
environmental benefits.

Practice Applies
Planning Conserving the right trees can reap rewards for developers, homeowners,
Considerations and communities. Healthy trees enhance property values and community
development by providing shade, wildlife habitat, and beauty. Sickly, stressed
trees reduce property values, discourage potential buyers and detract from a
community. Post -construction maintenance and removal of trees is difficult
and expensive. Replacing trees after construction can also be costly and time
consuming.
Preserving and protecting trees and other natural plant groups often results in
a more stable and aesthetically pleasing development. During site evaluation,
note where valuable trees and other natural landscape features should be
preserved, then consider these trees and plants when determining the location
of roads, buildings, or other structures.
Trees that are near construction zones should be either protected or removed
because damage during construction activities may cause the death of the tree
at a later time.
Trees should be considered for preservation for the following benefits:
• They stabilize the soil and prevent erosion.
• They reduce stormwater runoff by intercepting rainfall, promote
infiltration, and lower the water table through transpiration.
• They moderate temperature changes, promote shade, and reduce the force
of wind.
• They provide buffers and screens against noise and visual disturbance,
providing a degree of privacy.
• They filter pollutants from the air, remove carbon dioxide from the air,
and produce oxygen.
• They provide a habitat for animals and birds.
• They increase property values and improve site aesthetics.
Consider the following characteristics when selecting trees to be protected and
saved:
Tree vigor —Preserve healthy trees. A tree of low vigor is susceptible to
damage by environmental changes that occur during site development. Healthy
trees are less susceptible to insects and disease. Indications of poor vigor
include dead tips of branches, small annual twig growth, stunted leaf size,
sparse foliage, and pale foliage color. Hollow or rotten trees, cracked, split, or
leaning trees, or trees with broken tips also have less chance for survival.
Tree age —Old, picturesque trees may be more aesthetically valuable than
smaller, younger trees, but they may require more extensive protection.
Tree species —Preserve those species that are most suitable for site conditions
and landscape design. Trees that are short-lived or brittle or are susceptible to
attack by insects and disease may be poor choices for preservation.
Tree aesthetics —Choose trees that are aesthetically pleasing, shapely, large,
or colorful. Avoid trees that are leaning or in danger of falling. Occasionally,
an odd -shaped tree or one of unusual form may add interest to the landscape if
strategically located. However, be sure the tree is healthy.
Wildlife benefits —Choose trees that are preferred by wildlife for food,
cover, or nesting. A mixture of evergreens and hardwoods may be beneficial.
Evergreen trees are important for cover during the winter months, whereas
hardwoods are more valuable for food.
Construction activities can significantly injure or kill trees unless protective
measures are taken. Although direct contact by equipment is an obvious
means of damaging trees, most serious damage is caused by root zone stress
from compacting, filling, or excavating too close to the tree. Clearly mark
boundaries to maintain sufficient undisturbed area around the trees.
Design Criteria 1. Take stock of trees on the site. Hire a professional arborist or urban forester
to inventory existing trees. An inventory records the variety, location, size,
and health of each tree. A proper tree inventory creates the foundation for
a successful tree protection plan. A professional can identify valuable trees
and those that need attention or removal. Identify any stressed trees that need
removal. Stressed, unhealthy trees have wilting leaves, dying limbs, thinning
crowns or other signs of declining health. Always remove insect-, disease-, or
storm -damaged trees prior to construction. This is fast, efficient, and saves
resources.
2. Draw a base map. Include all the important site features such as existing
vegetation, property lines, utility connections, slopes, and required setback
distances before drawing in the proposed building(s):
• Map grading and drainage.
• Identify priority trees for protection. Mark their locations on the base map
and sketch in approximate tree protection zones where temporary fences
should be located around priority trees.
• Locate the building footprints: the areas where structures and their amenities
will affect the landscape. Draw in the driveways, parking areas, and decks.
• Mark trees that need to be removed or pruned to make room for future
structures and construction equipment.
3. Prepare a tree protection plan. A tree protection plan designates the valuable
trees that must be protected during the construction process. Assemble a team
to write a tree protection plan before ground is broken. The team should include
the site managers as well as professionals who can provide tree protection
advice (Table 1). Do not leave anyone out who should be involved. By working
together, the team can identify potential conflicts between construction needs
and tree protection, and identify compromise solutions.
Planning takes time, but it pays off during and after construction. Using the
base map, the team can plan for tree protection, foresee problems, and solve
them. Early planning helps to keep construction on schedule, reduce costs, and
avoid conflicts:
• Locate construction activities after considering the priority trees and the
development requirements.
• Look for potential conflicts, and explore alternate solutions.
• Consider grading and stormwater drainage. Remember that cutting or filling
around roots will weaken and eventually kill valuable trees. Weigh alternatives
such as retaining walls to protect priority trees.
• Designate tree protection zones (TPZs). The protection plan should specify
the location of temporary tree protection fences to protect trees and their
root zones during construction. TPZ fences identify "exclusion zones" where
construction and equipment use is prohibited. Effective TPZs maintain a
radius of at least 1.25 feet of protected area for each inch of trunk diameter
(Table 6.05a).

develop a schedule oftree maintenance activities, including watering, mulching,
and fertilization. Stay committed to this plan throughout the project.

Design Criteria
The following general criteria should be considered when developing sites in
wooded areas:
• Leave critical areas (such as flood plains, steep slopes and wetlands) with
desirable trees in their natural condition or only partially cleared.
• Locate roadways, storage areas, and parking pads away from valuable tree
stands. Follow natural contours, where feasible, to minimize cutting and
filling in the vicinity of trees.
• Select trees to be preserved before siting roads, buildings, or other
structures.
• Minimize trenching in areas with trees. Place several utilities in the same
trench.
• Designate groups of trees and individual trees to be saved on the erosion
and sedimentation control plan.
• Do not excavate, traverse, or fill closer than the drip line, or perimeter
of the canopy, of trees to be saved.

1. Erect TPZ fences. Restrict access to TPZs, with tall, bright, protective
Specifications
fencing. Most fencing is inexpensive and durable enough to last throughout
most construction projects. Temporary tree protection fencing should be
erected before clearing, deliveries and other construction activities begin on
the site.
2. Prohibit or restrict access to TPZs. All on -site workers should be aware
of the TPZs and the restrictions on activities within the zones. Use these TPZ
guidelines for the best effect:
• Post "keep out" signs on all sides of fencing. Do not store construction
equipment or materials in TPZs.
• Prohibit construction activities near the most valuable trees, and restrict
activities around others.
• Assess crew and contractor penalties, if necessary, to keep the TPZs intact.
3. Monitor trees. Vigilance is required to protect trees on construction sites.
Use a tree professional or train your staff to monitor tree health during and
after construction on a regular, frequent basis. Watch for signs of tree stress,
such as dieback, leaf loss, or general decline in tree health or appearance.
4. Monitor TPZ fences. Assign a crewmember the weekly responsibility
of checking the integrity of TPZ fences. Repair and replace TPZ fencing as
needed.
5.Optimize tree health. Assign a trained crewmember or hire a professional
to complete regular tree maintenance tasks, including watering, fertilization,
and mulching to protect tree roots. Consult a tree professional for advice on
these practices if needed. Survival of protected trees will increase if these
practices continue during construction. Healthy trees require undisturbed
healthy soils. Do not cause injuries to trees and roots. Do not change the soil,
grade, drainage, or aeration without protecting priority trees

Maintenance Continue to care for the site until the new owner takes possession. Take
these steps after all materials and equipment have been removed from the
site:
• Remove tree protection zone fences.
• Prune any damaged trees. In spite of precautions, some damage to protected
trees may occur. In such cases, repair any damage to the crown, trunk, or
root system immediately.
• Repair roots by cutting off the damaged areas and painting them with tree
paint. Spread peat moss or moist topsoil over exposed roots.
• Repair damage to bark by trimming around the damaged area as shown in
Figure 6.05d, taper the cut to provide drainage, and paint with tree paint.
• Cut off all damaged tree limbs above the tree collar at the trunk or main
branch. Use three separate cuts as shown in Figure 6.05d to avoid peeling
bark from healthy areas of the tree.
• Continue maintenance care. Pay special attention to any stressed, diseased, or
insect -infested trees. Reduce tree stress caused by unintended construction
damage by optimizing plant care with water, mulch, and fertilizer where
appropriate. Consult your tree expert if needed.
• Inform the property owner about the measures employed during construction,
why those measures were taken, and how the effort can be continued.

Definition Planting rapid -growing annual grasses, small grains, or legumes to provide
initial, temporary cover for erosion control on disturbed areas.
Purpose To temporarily stabilize denuded areas that will not be brought to final grade
for a period of more than 21 calendar days.
Temporary seeding controls runoff and erosion until permanent vegetation or
other erosion control measures can be established. In addition, it provides
residue for soil protection and seedbed preparation, and reduces problems of
mud and dust production from bare soil surfaces during construction.
Conditions Where On any cleared, unvegetated, or sparsely vegetated soil surface where
vegetative cover is needed for less than 1 year. Applications of this practice
Practice Applies include diversions, dams, temporary sediment basins, temporary road banks,
and topsoil stockpiles.
Planning Annual plants, which sprout and grow rapidly and survive for only one season,
are suitable for establishing initial or temporary vegetative cover. Temporary
Considerations 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 of appropriate 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 1 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. If the 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 top 4-6 inches of soil. Soils with a pH of 6 or higher need not be
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 roughening —If recent tillage operations have resulted in a loose
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 by disking, raking, harrowing, or other suitable methods.
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 6.1 Oa for seeding
in late winter and early spring, Table 6.IOb 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 hydroseeder. Use seeding rates given in Tables 6.1Oa-6.1Oc. 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).
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.

Definition Controlling runoff and erosion on disturbed areas by establishing perennial
vegetative cover with seed.
Purpose To reduce erosion and decrease sediment yield from disturbed areas, to
permanently stabilize such areas in a manner that is economical, adapts to site
conditions, and allows selection of the most appropriate plant materials.
Conditions Where Fine -graded areas on which permanent, long-lived vegetative cover is the
most practical or most effective method of stabilizing the soil. Permanent
Practice Applies seeding may also be used on rough -graded areas that will not be brought to
final grade for a year or more.
Areas to be stabilized with permanent vegetation must be seeded or planted
within 15 working days or 90 calendar days after final grade is reached, unless
temporary stabilization is applied.
Introduction During the initial phase of all land disturbing projects, the protective layer, either
natural or man-made, is removed from the earth's surface. As the protective
layer is removed, the resulting bare areas are exposed to the natural forces
of rainfall, freezing, thawing, and wind. The result is soil erosion that leads
to sediment pollution of North Carolina streams, rivers, lakes, and estuaries.
This design manual presents many alternative strategies for preventing erosion
and reducing sediment loss during the construction process. Establishment
of protective vegetative cover during the construction project, however, is
the crucial step in achieving soil stabilization, controlling soil erosion, and
preventing sedimentation ofwaterways. Without a sufficient amount of root mat
and leaf cover to protect and hold the soil in place, large volumes of soil will be
lost and waterways will be degraded long after projects are considered complete.
Sections of this practice standard address many of these various situations
and set forth selection criteria for the appropriate cover based on purpose and
adaptability. Some sediment and erosion control practices recommended in
earlier editions of the manual may no longer be applicable. For example, many
popular and commonly used seed and plant varieties have been identified as
invasive. Invasive plants are defined as species that aggressively compete
with, and displace, locally adapted native plant communities. In select cases
where no practical alternative is available, these plants may be considered on
a limited basis for soil stabilization, understanding that the goal is to eliminate
the use of all invasive plants in favor of non-invasive native and/or introduced
species that will provide an equally acceptable vegetative cover. Where there is
no alternative to the use of invasive species, measures need to be incorporated
in the installation and maintenance of these plants to limit their impacts.

It is imperative that disturbed soils be totallyprotected from erosion and sediment
loss during construction and before a project is considered complete and
acceptable. Installing appropriate vegetation in an immediate and timely fashion
is the optimal means of achieving this stabilization. Vegetative specifications
for most exposed soil conditions across North Carolina are provided in this
section of the manual. It should be noted however, that no two sites in the State
are exactly alike; therefore the protective vegetative cover for individual sites
should be carefully selected. Each requires its own investigation, analysis,
design and vegetative prescription as set forth in this section of the manual.
This practice standard describes three stages of vegetative cover; immediate,
primary and long term. Effective and acceptable stabilization can be provided
only when the optimum combination of immediate, primary, and long term
vegetative practices are applied.
The vegetative measures presented in this chapter include application of seed,
sod and sprigs. Use of field and container grown plants are not addressed
in this manual. Planting of these types of vegetation is typically at spacing
and intervals that will not provide the required protective cover. However,
the design professional is encouraged to utilize these larger plants to
compliment the required protective cover, particularly where these types of
plants will provide seed for continued long term cover and wildlife habitat.
PLANNING CONSIDERATIONS
SOILS
Test and analyze the type(s) and quality of the existing soils on a site, their pH
ranges, and their nutrient levels. Taking soil samples from the different areas
of the project site and having them tested at a state or independent lab will
provide a baseline for determining the pH modifiers and additional nutrients
required for the selected plant varieties.
Disturbed conditions on a site may produce a variety of soil communities.
Nutrient and pH levels in deeply cut soils will be quite different from those
soils found on the original surface. When sites are highly disturbed through
mechanical means such as grading, the soils become mixed together in many
different ratios. These areas should be identified and tested.
Results from soil tests will usually include recommended application rates of
soil modifiers such as lime and fertilizer for the selected plant species in the
particular soils. Application rates will be itemized in the report.
The texture of the soil on a site, which is the proportion of sand, silt, and clay
in the soil, is an important physical indicator of the site's ability to support
vegetation. In heavy clay soils amendments may be necessary to provide an
adequately drained planting medium. Conversely, in extremely sandy soils,
amendments may be required to provide for moisture and nutrient retention.

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.

SOIL PREPARATION
Proper soil preparation is necessary for successful seed germination and root
establishment. It is also necessary for 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 grassing, sprigging, sodding, and/or planting of
woody plants:
General Requirements:
• Preparation for primary/permanent stabilization shall not begin until all
construction and utility work within the preparation area is complete.
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) 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. Ripping consists of creating fissures in a criss-cross pattern over
the 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
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.
Areas to be Seeded:
• Till or disc the prepared areas to be seeded to a minimum depth of four
(4) inches. Remove stones larger than three (3) inches on any side, sticks,
roots and other extraneous materials that surface. If not incorporated
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 shall be removed and filled 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:
■ Immediate Stabilization — nurse crop varieties (Note: temporary mulching
may be utilized for immediate stabilization if outlined on the approved
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.
Where provisions are made for regular maintenance, primary vegetative
cover may be the end result. An example of primary vegetative cover being
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 6.11.a.)
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-term 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 plans. 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 6.1l.a through 6.11A 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
on the bid item list utilized for the project. If you did not obtain a soil test:
Follow these recommendations for all grasses except centipedegrass.
1. Apply 75 pounds of ground limestone per 1,000 sq. ft.
2. Apply a starter type fertilizer (one that is high in phosphorus) based on the
type of grass and planting method. Fertilizer bags have a three -number system
indicating the primary nutrients, such as 8-8-8 or 5-10-10. These numbers
denote the N-P-K ratio —the percentage of each nutrient in a fertilizer. The
percentages are always noted in the following order:
N Nitrogen for green color and growth.
P205 Phosphorus for good establishment and rooting.
K20 Potassium to enhance pest and environmental stress tolerance.
Some common examples of starter type fertilizers required for a 1,000 sq.
ft. area include 40 pounds of 5-10-10, 20 pounds of 10-20-20, or 16 pounds
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, storm water runoff, and wind. The availability of
the selected material and the means 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.

Practice Standards and Specifications
PROTECTIVE MATTING
Protective matting consists of an impervious cover secured to the soil surface
in lieu of vegetative cover. It is used to protect and stabilize the surface where
the process of seeding or planting forms of vegetation may cause more erosion
and off -site sedimentation than application of the mat. It is also used where a
disturbed area is intended to lay fallow for a period of time before additional
construction or land disturbance takes place. If a pervious matting is selected,
a combination of vegetation and matting is required. Seeds can be applied
prior to installation of the matting only after proper seedbed preparation
has been provided. Also, live stakes, dormant sprigs, and other vegetation
forms can be inserted in the pervious matting once it has been installed. Pre -
seeded pervious matting may be used for quicker root establishment and
stabilization only if certified dating and germination guarantees are provided.
The reviewing agency must approve all pre -seeded matting on site prior to
installation. Matting 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 6.17 for detailed specifications and
recommended product applications.
STABILIZATION IN WETLANDS, RIPARIAN BUFFERS, AND
FLOODPLAINS
Land disturbing activity involving streams, wetlands or other waterbodies
may also require permitting by the U.S. Army Corps of Engineers or the N.C.
Division of Water Quality. Approval of an erosion and sedimentation control
plan is conditioned upon the applicant's compliance with federal and State
water quality laws, regulations, and rules. Additionally, a draft plan should be
disapproved if implementation of the plan would result in a violation of rules
adopted by the Environmental Management Commission to protect riparian
buffers along surface waters. Care should be taken in selecting vegetative
stabilization of wetlands and riparian buffers to comply with permitting
requirements of other agencies, as well as provide adequate ground cover.
Planning Considerations for Land Disturbing Activities Within Wetland,
Riparian, and Floodplain Areas
Wetlands, riparian areas, floodplains, and/or terrestrial areas between streams
and uplands, serve to buffer surface water and provide habitat for aquatic and
terrestrial flora and fauna. When cleared and disturbed, these sensitive areas
are difficult to protect. Because of their proximity to water courses, relatively
high ground water tables, and flooding potential, detailed analysis and design
is necessary to determine the appropriate erosion control measures during
construction. Determining the appropriate and most expeditious means of
permanent vegetative stabilization in these areas requires equally detailed
analysis and design. The following considerations for erosion control and
stabilization should be taken into account during the design phase of the land
disturbing project where sensitive areas are involved:
• Obtain soil tests to determine the soil type, pH, texture and available
nutrients.
• Based on the soil tests provide a schedule of nutrients and other soil
amendments that will be required.
0
• Select a seeding mix of non-invasive species that will provide immediate
stabilization a short-term environment that will support and compliment
( pp p
permanent vegetative stabilization) and include a selective native
species mix that will eventually provide a permanent cover a long-term
P YP p ( g
environment that, with minimal maintenance, will provide adequate root
and leaf cover).
• Invasive species are to be avoided. If native species and introduced non-
invasive seed sources are not available, protective matting that will hold
and foster the development of native cover from adjacent seed sources
should be used. Continuous maintenance must be employed until the
selected species have matured and are no longer susceptible to competition
from invasive plants. If no alternative to the use of invasive seeds and
plants is available, invasives approved on the plans may be utilized only
with strict containment measures outlined in detail on the plans, in the
construction sequence and in the maintenance specifications.
• A quickly germinating nurse crop of non-invasive, non-competitive annual
grass species can be used along with native seeding and/or matting. These
temporary systems should be planted at minimal density so that they do
not inhibit the growth and establishment of the permanent, native species.
(See the plant chart in Table 6.1 La for recommended native and nurse
crop species.)
• Seed bed preparation is key to successful establishment of seeds. Particular
care should be taken, however, when working in wetlands, riparian areas,
or floodplains due to their sensitive nature. Careful consideration should
be given to the types and placement of large equipment working in these
areas. This process must be outlined in detail on the plan's construction
sequence.
• Installation techniques vary and should be planned for accordingly.
• A maintenance plan must be established for optimal plant establishment,
submitted with the plans and included in the bid list for the project.
Like all construction sites, wetlands, riparian areas, and floodplains will vary
widely in physical makeup across North Carolina. Different conditions will
dictate specific treatment, design and plant selection within the Mountains,
Piedmont, and Coastal Plain regions. Soil tests, seedbed preparation,
mulching, matting, and maintenance will be critical for successful vegetative
establishment and long-term protection of these environmentally sensitive
areas. Unavoidable impacts to these areas during land disturbing activities
need to be addressed in detail on the plan sheets and construction sequence.
Practice Standards and Specifications
Native Seed and Plant Selection for Stabilization of Wetlands, Riparian
Areas, and Floodplains
Upon the completion of the land disturbing activity, vegetative cover must
be established on all areas not stabilized by other means. If work in these
areas stops for more than 15 working days, temporary vegetative cover and/
or matting must be applied to all disturbed areas. The goal is to protect these
areas from erosion and to prevent sedimentation of adjacent streams, wetlands,
lakes, and other water bodies.
Planning considerations for wetlands, riparian areas and floodplains will
require additional research, detail and specifications. Native grasses are
usually required as a condition of a 401 Water Quality Certification or a trout
buffer variance.
Native vegetative species are plant species that naturally occur in the region in
which they evolved. These plants are adapted to local soil types and climatic
variations. Because most native species do not germinate and establish as
readily as some introduced species, it is necessary to provide a non-native
nurse crop or matting to stabilize the soil until the native crop can become
established as the dominant cover. Once established, the native plants will
produce an extensive root structure that, if properly maintained, will stabilize
soils and reduce erosive forces of rainfall and overland stormwater flow. Many
of these plants also possess characteristics that, when established, allow them
not only to survive, but also to thrive under local conditions.
Seeding a mixture of perennial native grasses, rushes, and sedges is a way
to establish permanent ground cover within wetlands, riparian areas and
floodplains. The use of propagated plants is another method of reestablishing
natives in these environments. Selecting a seed mixture and/or propagated
plants of different species with complimentary characteristics will provide
vegetation to fill select niches on sites with varying physical conditions.
The design professional should note that because most native species do not
germinate and establish as readily as some introduced species, it is necessary
to provide a non-native nurse crop or matting to stabilize the soil until the
native crop can become established as the dominant cover. For additional
information about acceptable nurse crop varieties, consult the planting list in
Appendix 8.02, local seed and plant suppliers, the North Carolina Cooperative
Extension Service or a qualified design professional to assure the proper
selection and plant mix.
0
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
(i.e., dry sandy alluvial floodplains with wet pockets). Therefore, thoughtful
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
6.11 a-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 seed bed per the most current
guidance in Carolina Lawns, NCSU Extension BulletinAG-69, or Practice
6.12 Sodding.

• Woody plants (liners, container, B&B) — These materials are typically
used to complement an herbaceous protective cover. They eventually
are major components of long-term, permanent stabilization and should
be chosen and planned in conjunction with immediate and long-term
maintenance. The plants should be selected and specified by the design
professional for each individual project. See Practice 6.13 Trees, Shrubs,
Fines, and Ground Covers.
MAINTENANCE
The absence of or an incomplete landscape management specification and/
or complete maintenance schedule shall constitute grounds for disapproval of
the plans. Proper maintenance is critical for the continued stabilization once
vegetative cover is established. Although maintenance strategies for different
sites may be similar, no two construction sites in North Carolina have been
or will be able to be controlled or protected in identical ways. Variations in
climate, topography, soils, available moisture, size and many other conditions
will dictate the maintenance methodology to be used. A detailed schedule of
maintenance will be required on the plans. This schedule will illustrate how
the initial planting will be maintained to assure immediate, short term and
permanent protection. The schedule will address topics such as appropriate
irrigation of plants during the early establishment phase, drought conditions,
excessive rainfall, mulch replacement, supplemental seeding, supplemental
soils tests, application of nutrients and amendments, control of competitive
and invasive species, disease and insect control, and corrective maintenance,
measures to address failure of vegetation to become established. Contractual
responsibility for maintenance after initial establishment of vegetative cover
will be provided on the plans, in the construction sequence and on the bid list
for the project. Maintenance bonds and/or warranty guarantee may be required
of the responsible party, especially for areas in or adjacent to environmentally
sensitive sites such as wetlands, riparian buffers, floodplains, and waters of
the State. See Example 6.11a for a sample maintenance specification and a
minimum maintenance check list that shall be provided on all plans.
RECOMMENDED BID LIST

planting pertaining to vegetative stabilization of land disturbing projects in
North Carolina.)
• Soil test prior to grading (price per each test).
• Soil test during grading operations (price per each test).
• Soil test at completion of grading and/or prior to seeding, sprigging,
sodding and application of fertilizer, lime, and other soil amendments

• Mowing (price per square foot).
SEEDING RECOMMENDATIONS
The following tables list herbaceous plants recommended for use as nurse
crops for immediate stabilization and primary crops for initial and long-term
stabilization. Nurse crops are expected to develop in two to five weeks and,
with adequate maintenance, be an effective method of soil stabilization for
a period of six months to one year. Nurse crops are not effective as primary
long-term cover, however if properly maintained they can be an adequate
cover and protection for the development of primary crops.
The goal for a primary crop is for it to develop over a three-week to one-year
period and be effective up to three years with a well-defined maintenance
program. The long-term goal for a primary crop is the initial step toward
a sustainable protective cover without the need of maintenance. Where the
primary crop is intended for a managed lawn and landscape aesthetics, the
effective period can be extended by a more intense maintenance program.
Where native species are utilized and become established during the planned
maintenance program, a permanent cover that will support future succession
species should exist and require little or no additional maintenance or
management.
In uses of both nurse and primary crops, the development periods listed on the
tables are optimal based on normal climatic conditions for the planting dates
listed. The sediment and erosion control maintenance program must recognize
that optimum temperatures and rainfall are the exception rather than the rule.
The design professional needs to provide flexibility in the stabilization plan
to address the potential ranges of temperature and moisture conditions we
experience in North Carolina.
Information is provided for seeding rates, optimum planting dates in the state's
three regions, sun and shade tolerance, invasive characteristics, compatibility
in wetlands and riparian buffers, and installation maintenance considerations.
By going through the lists the design professional can select the nurse and
primary seed varieties and maintenance characteristics they feel are best suited
for their site conditions, vegetation management expertise and maintenance
capabilities.
To use the information in the seeding charts the plan preparer must:
• Determine what nurse crop best fits their site, soil conditions, and
permanent seed mix.
• Obtain soil tests for all areas to be seeded.
• Know the site's region: mountains, piedmont, or coastal plain.
• Know if the areas to be seeded are sunny, part shade, or full shade.
• Know if the areas are well or poorly drained.
• Know if wetlands or riparian buffers are included in the areas to be
seeded.
• Know if a chosen crop is invasive and if so, what potential impacts it will
have on the site and adjacent properties.
With this knowledge the plan preparation may proceed utilizing the charts
provided to provide the several seed mixes that will be applicable to the
different areas requiring stabilization.

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.

NOTES
Example 6.1 La GUIDELINES FOR WRITING MINIMUM LANDSCAPE MANAGEMENT SPECIFICATIONS
Following is an outline that demonstrates what should be included in specifications that will insure the long term
stabilization of disturbed sites in North Carolina. As noted before in this manual, each construction site in the
state is unique and has features that will require special provisions for revegetation and stabilization. The outline
provided below cannot address these individual sites. It is the responsibility of the design professional and the
financially responsible party to see that the specifications are edited to fit their site and to assure that permanent
stabilization is achieved.
General Provisions
A. Intent:
1. These specifications are prepared with the intent of promoting outstanding performance in long-
term stabilization. They are to be used as guidelines in establishing sediment control and vegetative standards
for the sites. Final technical decisions such as herbicides, fertilizer ratios, times of application and schedules
are to be determined by the Contractor, who has the responsibility to obtain soil test and to manage the
vegetation to achieve the desired results. The maintenance specifications must address maintenance for
sediment and erosion control vegetation during construction and for permanent/long-term stabilization.
B. Description of Work:
1. Perform all work necessary and required for the (insert period of contract) maintenance of the project as
indicated on the drawings, in the project manual, and specified herein.
2. Licensing:
a) Contractor shall provide verification of current, applicable pesticide applicator licensing for
each applicator that will handle pesticides on the contracted sites.
3. Contract Administration
a) Staffing: The Contractor shall provide adequate staffing, with the appropriate expertise, to
perform all required work.
b) Monthly Site Review meetings will be held. Attendees will include the Contractor's Project
Manager and Site Foreman and the property manager or other representative designated by the
financially responsible party. Result of site reviews will be documented and circulated to the
attendees and the owner by the contractor.
c) The Contractor will communicate with the proper person on a monthly basis to summarize
work performed and immediately notify the project manager of any failure of the site to remain
stabilized.
II. Materials
A. Soil Additives: Additives are to be applied per soils test taken prior to, during and after construction. (Use
this section to provide the types and quantities of fertilizers, lime, and other soil amendments called for in
the soils P
report. Include all soils test reports in the specifications document. This narrative or list should
P P
include quantities, rates, mixes, organic information, manufacturer, sources, and other information
suggested in the soils test.)
6.11.20
1. INLET MAINTENANCE SHALL BE DOCUMENTED IN PROJECT LOG BOOK.
2. FILTER TYPES SHALL BE APPROVED BY THE CITY INSPECTOR PRIOR
TO INSTALLATION.
3. FILTER BAGS MAY BE REMOVED WHEN SITE IS STABILIZED AT
THE DIRECTION OF THE ENGINEER.
4. FILTER BAGS SHALL BE REMOVED PRIOR TO STREET ACCEPTANCE.
5. FILTER BAGS SHALL BE CLEANED OR REPLACED ON A REGULAR
HOOD BASIS (NOT BE MORE THAN HALF FULL AT ANY TIME).
6. FILTER BAGS SHALL NOT BE ALLOWED IN EXISTING CITY OR NCDOT
ROADS.

NPDES Stormwater Discharge Permit for Construction Activities (NCGO1)
A. Pesticides:
1. Establish an Integrated Pest Management (IPM) program for the site that relies on targeted insect and
disease control coupled with sound stabilization management and water management practices.
2. These specifications do not include pesticide treatments for infestations of Southern Pine Beetle, Gypsy
Moth, or Fire Ants. The contractor shall notify the Owner if these pests are observed on site.
3. All pesticides shall be applied by a North Carolina licensed applicator in accordance with all State and
Federal regulations and per manufacturer's recommendations.
B. Mulches: Mulch for areas not subject to erosion and over wash by storm water should be called out in
this section addressing its maintenance, replacement, removal and conversion to other uses. Those subject to
erosion and over wash by storm water must be addressed on the plans and in the calculations.
III. Execution
A. General:
1. Good long term stabilization is based on the proper maintenance, management and balance of nutrients,
soil moisture and general cultural practices. It is recognized that fewer fungicide and pesticide treatments as
well as lower fertility rates are required with a well managed, balanced landscape. The following section is
meant to promote this balance and therefore do not highlight specific quantitative standards. (Quantitative
standards should be addressed as site specific by the design professional in conjunction with the
owner and contractor.) Calendar references are general and are to be used only as a guide. Weather and
soil conditions that are most appropriate for a given process, procedure and/or area of the state shall be the
determining factor in scheduling work.
B. Soil Tests:
1. After the soil test prior to stabilization, tests shall be made yearly in the fall to determine the required soil
additives for all stabilized areas. If known nitrogen requirements are not specified by previous test, they
need to be determined by the subsequent soils test and the proper applications made. Fertilizer ratios may
be determined through analysis of the soil tests coupled with the contractor's experience and knowledge of
the site.
C. Mowing
Rev. 5/08
1. Mowing for maintained turf/lawns
a. Mow areas intended for "groomed appearance" on a schedule during the growing season
and as required throughout the year to provide the desired appearance. (Establish a mowing
frequency here that addresses the specific plant species used and their growing habits.) This
frequency will be a minimum standard. Particular properties and their peculiar characteristics
as well as individual plant species may require mowing more often than the stated minimum
may be required. This should be noted in this section.
b. The range of turf species suggested for lawns in the three growing regions of North Carolina
vary as to optimum maintained height. The selected species should be maintained at a height
recommended by the seed producer. Do not cut too short and do not allow the turf to attain
a height that will cause the crop to decline or die. Consult individual seed producers and/or
packaging for recommended mowing heights.
c. Mow with a mulching mower to limit the amount of clippings removed, or mow and blow in
such a manner that clippings are not evident and not to adversely effect the growing capacity

and/or health of the existing vegetation turf. It is important clippings are allowed to remain
spread throughout the lawn area, to the extent possible, so that they might aid in building a
more productive soil profile and root zone.
2. Mowing other stabilized areas to promote continued growth. Include mowing specification here for other
stabilized areas which require maintenance but not a "groomed" appearance. Also include specifications
for mowing areas where it is desirable for woody native volunteer vegetation to become established. This
should include attention to mowing stakes or other way of protecting the desired woody natives from the
mowing operation.
D. Watering
1. Irrigation System Maintenance and Monitoring: If stabilized areas are to be irrigated the design
professional should include specifications for the system, its maintenance and its operation in this section.
2. In the absence of an automatic or manual irrigation system, provisions for providing adequate water to
stabilized areas should be addressed in this section.
3. (Provisions should be made in this section for adjustments to application rates of water during
times of regulated droughts and/or periods of excessive rainfall.)
E. CONTROL OF INVASIVES: Competition from invasive species can be detrimental to the establishment
of the permanent vegetative cover. Left unchecked, these invasives can undermine a revegetation process in
a short period of time and eventually lead to unprotected soil and sediment damage. Make site observations
monthly to check for the presence of such species and, if found, treat them immediately with the appropriate
cultural practices and/or by the use of seasonally -appropriate and site appropriate herbicides.
F. Maintenance items including fertilization, mowing, continued soils testing, repair, mulching, matting and
soil preparation are to be addressed in the approved construction sequence and on the project bid list.

Practice Standards and Specifications
Definition The stabilization of temporary construction access routes, on -site vehicle
transportation routes, and construction parking areas.
Purpose To control erosion on temporary construction routes and parking areas.
Conditions Where All traffic routes and parking areas for temporary use by construction traffic.
Practice Applies
Planning Improperly planned and maintained construction roads can become a continual
Consideration s erosion problem. Excess runoff from roads causes erosion in adjacent areas,
and an unstabilized road may become a dust problem. Construction vehicle
traffic routes are especially susceptible to erosion because they become
compacted, and collect and convey runoff water along their surfaces. Rills,
gullies, and troublesome muddy areas form unless the road is stabilized.
During wet weather, unstabilized dirt roads may become so muddy they are
virtually unusable, generating sediment and causing work interruption. Proper
grading and stabilization of construction routes often saves money for the
contractor by improving the overall efficiency of the construction operation
while reducing the erosion problem.
Situate construction roads to reduce erosion potential, following the natural
contour of the terrain. Avoid steep slopes, wet or rocky areas, and highly
erosive soils.
Controlling surface runoff from the road surface and adjoining areas is a key
erosion control consideration. Generally locate construction roads in areas
where seasonally high water tables are deeper than 18 inches. Otherwise,
subsurface drainage may be necessary. Minimize stream crossings and
install them properly (Practices 6.70, Temporary Stream Crossing and 6.71,
Permanent Stream Crossing).
When practical, install permanent paved roads and parking areas and use them
for construction traffic early during the construction operation to minimize
site disruption.
Design Criteria Road grade —A maximum grade of 10% to 12% is recommended, although
grades up to 15% are possible for short distances.
Road width-14 feet minimum for one-way traffic
—20 feet minimum for two-way traffic
Side slope of road embankment-2:1 or flatter.
Ditch capacity —Roadside ditch and culvert capacities-10-year peak
runoff.
6.80.1
6.80.2
0
Stone surface —Use a 6-inch course of "ABC' or "base course" or larger as
specified in N.C. Department of Transportation Standard Specifications for
Roads and Structures.
Permanent road standards —Design standards are available from the N.C.
Department of Transportation Division of Highways District Engineer. Follow
these specifications for all permanent roads.
Construction 1. Clear roadbed and parking areas of all vegetation, roots, and other
objectionable material.
Specifications
2. Ensure that road construction follows the natural contours of the terrain if
it is possible.
3. Locate parking areas on naturally flat areas, if they are available. Keep
grades sufficient for drainage, but generally not more than 2 to 3%.
4. Provide surface drainage, and divert excess runoff to stable areas by using
water bars or turnouts (References: Runoff Control Measures).
5. Keep cuts and fills at 2:1 or flatter for safety and stability and to facilitate
establishment of vegetation and maintenance.
6. Spread a 6-inch course of "ABC' crushed stone evenly over the full width
of the road and smooth to avoid depressions.
7. Where seepage areas or seasonally wet areas must be crossed, install
subsurface drains or geotextile fabric cloth before placing the crushed stone
(Practice 6.81, Subsurface Drain).
8. Vegetate all roadside ditches, cuts, fills, and other disturbed areas or
otherwise appropriately stabilize as soon as grading is complete (References:
Surface Stabilization).
9. Provide appropriate sediment control measures to prevent off -site
sedimentation.
Maintenance Inspect construction roads and parking areas periodically for condition of
surface. Topdress with new gravel as needed. Check road ditches and other
seeded areas for erosion and sedimentation after runoff -producing rains.
Maintain all vegetation in a healthy, vigorous condition. Sediment -producing
areas should be treated immediately.
