TemDOrary Stabilization
Temporary Stabilization is defined as a condition where exposed soils or disturbed areas
are provided a temporary vegetative and/or non -vegetative protective cover to prevent
erosion and sediment loss. Temporary stabilization may include temporary seeding,
geotextiles, mulches, and other techniques to reduce or eliminate erosion until either final
stabilization can be achieved or until further construction activities take place to
re -disturb this area.
Initiatina Temporary Stabilization
Initiate temporary stabilization by mulch or temporary stabilization by seeding within 7
calendar days where land disturbing activities have temporarily ceased on the Project and
will not resume for a period exceeding 14 calendar days. Where land disturbing
activities on a portion of the Project are temporarily ceased, and the land disturbing
activities are resumed within 14 days, temporary stabilization measures are not required
to be initiated on that portion of the Project.
Temporary stabilization by seeding is required if the Project will not be worked for a
period longer than 60 days.
Initiate temporary stabilization measures as soon as practicable for areas where initiating
temporary stabilization measures within 7 days is infeasible (e.g., where snow cover,
frozen ground, or drought conditions preclude stabilization).
Temporary Stabilization
Acceptance of Temporary Stabilization
Before acceptance of temporary stabilization by the regulatory agency and the Design
Engineer or Landscape Architect, temporary stabilization is required that is sufficient to
control erosion for a given area and length of time before the next phase of construction or
the establishment of permanent seeding is to commence. A satisfactory stand of temporary
stabilization meeting the requirements of this Specification is required regardless of the time
of the year the work is performed.
Temporary Cover by Mulch
Use temporary cover by mulch where it is not feasible or practicable to bring an area to
final slope and grade. Finish the surface so that permanent seeding can be performed
without subsequent disturbance by additional grading.
Temporary Cover by Seedina
Following the preparation of the seedbed, sow seed per the seeding Tables and apply an
appropriate Mulch prior to a rainfall event that compacts the seedbed. The CONTRACTOR may
add granular lime and fertilizer as necessary to enhance growth.
Final Stabilization
Final Stabilization is defined that all land -disturbing activities at the construction site have
been completed and that on all areas not covered by permanent structures, either
(1) A uniform (e.g., evenly distributed, without large bare areas) permanent vegetative cover
with a density of 70 percent has been established, or
(2) Equivalent permanent stabilization measures (such as the use of landscaping mulch,
riprap, pavement, and gravel) have been implemented to provide effective cover for exposed
portions of the construction site not stabilized with permanent vegetation.
Final stabilization by vegetation must be achieved with permanent perennial vegetation
prior to issuing the Notice of Termination (NOT).
Permanent Seedin
Initiate permanent seeding within 7 calendar days where land disturbing activities have
permanently ceased on the Project. Where land disturbing activities are resumed within 14
days, stabilization measures are not required to be initiated on that portion of the Project.
Initiate permanent seeding measures as soon as practicable for areas where initiating
permanent seeding measures within 7 days is infeasible (e.g., where snow cover, frozen
ground, or drought conditions preclude stabilization).
When performing permanent seeding for permanent detention ponds, ensure that the detention
pond is cleaned of any deposited sediment and graded to the required permanent detention
basin configuration. Ensure the seedbed for the permanent seeding is established in
accordance with this Specification.
Acceptance of Permanent Seedina
Before acceptance, a uniform perennial vegetative cover with a density of 70% of each
square yard of the seeded area is required. A well developed root system must be
established to sufficiently survive dry periods and winter weather and be capable of
reestablishment in the spring.
Permanent Seedina Installation
Following the preparation of the seedbed, perform permanent seeding per the seeding Tables
and apply an appropriate Mulch within 5 working days and/or prior to a rainfall event that
compacts the prepared seedbed. If a rain event occurs that compacts or erodes the
seedbed prior to performing permanent seeding, the seedbed must be re -prepared prior to
conducting permanent seeding. Add fertilizer and lime as required by a soil test.
Sod
Initiate Sod applications within 7 calendar days where land disturbing activities have
permanently ceased on the Project. Initiate Sod applications measures as soon as practicable
for areas where initiating Sod applications within 7 days is infeasible (e.g., where snow cover,
frozen ground, or drought conditions preclude stabilization). Use Sod on slopes less than
2HAV.
Acceptance of Sod
Acceptance is contingent on establishing a satisfactory stand of perennial grass. Sod
application areas are acceptable when all requirements including maintenance are met and a
healthy, evenly colored, viable stand of grass is established. A satisfactory stand of grass
must have a root system that is sufficient to survive dry periods and winter weather and is
capable of re-establishing in the spring.
Sod
Do not use sodding on slopes steeper than 2HA V, and if sodding is mowed, do not
place on slopes greater than 3HAV. Install Warm Season Sod between March 1st and
September 1st. Install Cool Season Sod anytime during the year as long as the soil is
not frozen. Do not place Sod on:
Soil that is frozen and/or when the 10-day forecasted low temperature remains below
35 degrees Fahrenheit;
Soil that is excessively wet;
Soil that is excessively dry (periods of heat or drought) unless watering is specified;
Soil that is composed of compacted clay; and
Soil than has been treated with pesticides.
Sod Bed Preparation
Ensure the Sod bed is uniform and conforms to the finished grade of the Project.
Loosen the Sod Bed to a minimum depth of 3 inches before placing Sod.
Furnish and place topsoil or compost in the Sod Bed in areas where the existing Sod
Bed has little or no topsoil,
Lay Sod when Sod Bed is moist. Moisten dry Sod Beds before sod is laid.
Sod Material
Provide Sod with living, well -established growth, with a dense root mat of predominant
grass Specified. Provide vigorous, well rooted, healthy turf, free from disease, insect
pests, weeds, other grasses, stones, and any other harmful or detrimental materials.
Sod Installations
Ensure Sod is not installed until the end of the project or when final stabilization is
achieved on adjacent areas of the project that drain or discharge to the Sod application.
Lime
Agricultural Granular Lime
Use agricultural grade, standard ground limestone for all permanent seeding applications
and Sodding applications.
Applying Granular Lime
A soil analysis is recommended prior to application. Apply at a rate within ±10% of
weight recommendation of soil analysis. Do not apply more than 2,500 Ibs/acre of in a
single application.
Fast Acting Lime
Use fast acting liquid and/or dry forms of lime for all temporary seeding and permanent
seeding applications.
Fertilizer
Granular Fertilizer
Use for all permanent seeding applications and all Sodding applications. Proper mixture is
dependent on the existing soil conditions and it is recommended that a soil analysis be
performed if the soil conditions are uncertain in the area of fertilizer application.
Use fertilizer that incorporates a minimum of 50% water insoluble (slow release)
nitrogen . Animal by-product or municipal waste fertilizers are not acceptable under this
Specification.
Unless a soil analysis is performed to determine otherwise, a good rule of thumb
granular fertilizer to apply in the Upstate of South Carolina is 10-10-10. In no case
should a 20-20-20 fertilizer be used due to the potential burning of the seedbed.
Compost Soil Amendment
For seedbeds that have little or no topsoil, are highly acidic, or are lacking sufficient
nutrients to sustain a health stand of grass place, and mix certified weed free compost
into the seedbed to ensure a good stand of grass.
Biological Growth Stimulant
Use for all permanent seeding, Sodding, and temporary seeding applications. Animal
by-products or municipal waste products are not acceptable. Liquid fertilizers are not
acceptable, and can cause burning of the seedbed if applied as such.
Seeding Dates and Rates of Application
Perform seeding during the periods and at the rates specified in the seeding tables. Do
not use temporary cover by seeding or permanent seeding for projects when:
The ground is frozen and/or when the 10-day forecasted low temperature remains
below 35 degrees Fahrenheit;
The ground is excessively wet; or
The ground is excessively dry (periods of drought) unless watering is specified.
During periods of adverse conditions, use temporary cover by mulch.
Seedbed Preparation
Ensure that the areas receiving permanent seeding are uniform and conform to the
finished grade of the Project.
Perform minor shaping and evening of uneven and rough areas outside of the
graded area in order to provide for more effective erosion control and for ease of
subsequent mowing operations.
Loosen the seedbed (including cut slopes) to a minimum depth of three (3) inches
before initiating permanent seeding and temporary seeding.
An acceptable method of preparing the seedbed on slopes is vertically tracking the
seedbed up and seedbed up and down the slope with proper equipment.
Remove stones larger than two and one-half (21/2) inches in any dimension, large
dirt clods, roots, or other debris brought to the surface.
Use compost if good seedbed material is not located on site or results of the soil
test show the seedbed is excessively nutrient deficient to the extent of requiring costly
fertilizer additions and or have excessively low pH values (lower than 5.0).
Consider the use of mechanical seed drills to perform permanent seeding on areas
where temporary seeding or temporary cover by mulch was previously utilized.
Mulch
Required for all permanent seeding, temporary seeding, and temporary cover applications.
Do not use Mulch in areas where concentrated flow is expected. Use HECP Mulch for
temporary seeding and temporary cover applications when the application area will require
additional grading prior to permanent seeding. Do not use Erosion Control Blankets
(ECB) or Turf Reinforcement Matting (TRM) in this situation.
Wood Chip Mulch
Wood chip mulch is not acceptable for seeding applications. If wood chip mulch is used
for temporary cover by mulch, it must be removed prior to performing permanent
seeding
Straw or Hay Mulch with Tackifier
Use material that is certified weed. Do not use on slopes steeper than 4HA V. Anchor
using one of the following tacking agents:
Organic or Chemical Tackifier
Hydraulic Straw Tackifiers
Emulsified Asphalt
Applying Straw or Hay Mulch
Uniformly apply material at the rate of 2,000 pounds per acre.
Compost Mulch
Only use from producer that participates in the USCC STA program. Do not use
materials that have been treated with chemical preservatives as a compost mulch. Do
not use mixed municipal solid waste compost.
Hydraulic Erosion Control Products (HECPs)
Use as an allowable mulch for temporary cover by mulch, temporary cover by seeding
or permanent cover by seeding applications. Do not use as a channel liner or for areas
receiving concentrated flow.
Temporary Erosion Control Blankets (ECB) and Turf Reinforcement Mattina (TRM)
Consider for permanent seeding application areas with steep slopes or areas where there
is a significant erosion problem or potential for erosion. Use in areas where
concentrated flow is expected. Do not use for temporary seeding applications when the
application areas will require additional grading or modifications prior to permanent
seeding.
Protection of Structures
Cover any parts of bridges, culverts, guardrails, signs, sidewalks, curb and gutters, catch
basins, pipe ends, and other structures as necessary to prevent discoloration before
spraying HECPs, organic or chemical tackifiers.
Slope Interruption Devices
The maximum allowable continuous slope length for straw or hay mulch, HECPs, compost
and ECB applications is 50 feet. Slope interruption devices (such as sediment tubes) or
TRMs are required for continuous slope length longer than 50 feet.
Inspection
Ensure that all seed, Sod, fast acting lime, biological growth stimulants, agricultural
granular lime, granular fertilizer, straw and hay mulch, HECPs, compost mulch, and ECBs
are applied as Specified. The Design Engineer or Landscape Architect, or member of the
Design Engineer or Landscape Architect staff must document on -site that these materials
are applied correctly by completing and signing proper forms.
Perform all maintenance necessary to keep Stabilization areas in a satisfactory condition
until the work is finally accepted. This includes mowing, repairing areas of erosion and
washes, and applying additional seed, fertilizer, and mulch to areas where a satisfactory
stand of grass has not been achieved.
Mowing
Mow road shoulders and medians when vegetation reaches a height of approximately 18
to 24 inches. Do not perform excessive mowing of Slopes resulting in ruts, furrows or
grooves. Do not perform excessive mowing of Slopes that inhibits the establishment of
the slope vegetation. Do not perform mowing when soil and weather conditions are such
that rutting or other damage to the Project may occur.
Ensure mowing results in a uniform vegetation height of 4 to 6 inches, unless otherwise
directed. When utilizing a nurse crop for permanent seeding, mow Millet (no lower than 3
inches) once it reaches a height of 18 inches to reduce competitiveness with the
permanent vegetation. Mow Wheat and Rye Grain (no lower than 3 inches) once they
reach a height of 6-8 inches to reduce competitiveness with permanent vegetation.

CHANNEL
INSTALLATION
DETAIL
1. Prepare soil before installing rolled
erosion control products (RECPs),
including any necessary application of
lime, fertilizer, and seed.
2. Begin al the lop of the channel by
anchoring the RECPs in a 6"(15cm)
deep X 6"(15cm) wide trench with
approximately 12"(30cm) of RECPs
extendetl beyond the up -slope portion
of the trench. Use ShoreMax mat at the
channel/culvert outlet as supplemental
our protection as needed. Anchor the
RECPs with a row of staples/stakes
approximately 12"(30cm) apart in the
bottom of the trench. Backfill and
compact the trench after stapling. Apply
seed to the compacted soil and fold the
remaining 12"(30m) portion of RECPs
back over the seed and compacted soil.
Secure RECPs over compacted soil
with a w of staples/stakes spaced
approximately 12" apart across the
width of the RECPs.
3. Roll center RECPs in direction of water
flow In bottom of channel. RECPs will
unroll with appropriate side against the
soil surface. All RECPs must be
urely fastened to soil surface by
placing staples/stakes in appropriate
locations as shown in the staple pattern
guide.
4. Place consecutive RECPs entl-over-end
(Shingle style) with a 4".6" overlap. Use
S
double row of staples staggered 4"
aPart
and 4" on center to secure
RECPs.
5. Full length edge of RECPs at top of side
slopes must be anchored with a row of
staplewstakes approximately 12"(30cm)
apart in a 6"(15cm) deep X 6"(15cm)
wide trench. Backfill and compact the
trench after stapling.
6. Adjacent RECPs must be overlapped
approximately 2"-5" (5-12.5cm)
(Depending on RECPs type) and
stapled.
7.In high Flow channel applications a
staple check slot is recommended at 30
to 40 foot (9 -12m) intervals. Use a
double row of staples staggered
4"(10an) apart and 4"(10cm) on center
over entire width of the channel.
8. The terminal end of the RECPs must be
anchored with a row of staples/stakes
approximately 12"(30an) apart in
6"(15cm) deep X 6"(15cm) wide trench.
Backfill and compact the bench after
stapling.
