AREA TO BE DISTURBED: 55. / V ACRES
The erosion on this tract will be controlled with sediment traps as indicated on the plan.
In the event of any additional temporary ditching, check danns will be siixd and installed to
contain 1800 cu.fl./acre of the area contributing to said temporary ditches. A revised plan will be
required and re -submitted for approval prior to any additional ditching,
Also enclosed in this plan are:
1. Construction sequence
2. Erosion Control Site Plan with...
a, Vegetation and seeding plan
b. Construction entrance
c. Temporary sediment traps
3. Energy Dissipator
SCHEDULING OF WORK: Clearing and grubbing shall be scheduled and performed in
such a manner that subsequent grading operation and erosion control practices can follow
immediately thereafter. Excavation, burrow and embankment operations will be conducted such that
cuts and fills will be completed to final grades in a continuous operation. All construction areas not
otherwise protected shall be planted with permanent vegetative cover in accordance with the
Specifications within 30 working days after completion of active construction.
MINIMUM AREAS TO BE DISTURBED: Only those areas necessary for timely and
proper completion of the project shall be stripped of native vegetation.
No land disturbing activity, except street crossings, shall be permitted in proximity to a natural
watercourse without a buffer zone along the margin of the watercourse of sufficient width to confine
visible siltation within the 25 percent of the buffer zone nearer the land disturbing activity.
The angle for graded slopes and fills shall be no greater than the angle which can be retained
by vegetative cover or other adequate erosion control devices or structures. Slopes left exposed Ardl
within its working days of completion of any, place of grading, be planted or otherwise provided with
ground cover, devices, or structures sufficient to restrain erosion
PLACEMENT OF SEDIMENT CONTROL DEVICES: All devices for sediment control
shall be constructed prior to beginning clearing and grubbblg on site. The work includes the seeding
and grassing of the denuded areas. As soon as practicable after finish grades have been established,
all operations in connection with grassing shall be performed. h4ulch shall be used where required
for stabilization of repaired areas. If vegetation has not stabilized the soil during the growth period
mentioned above, jute matting shall be installed on eroded slopes. See altern,te temporary and
permanent seeding schedule on the plan.
SEEDS: For fall planting, the grass seed shall be unhulled Bermuda Seed ti "I If 82% pure five
seed having a germination of 85eb, Kentucky 31 tall fescue with 88% pure live seed having a
germination of 85%, and Carpet Grass Seed with 80% pure five seed having a germination of 85%.
For spring planting, no change shall be made in composition except that the seed will be hulled.
FERTILIZER: Fertilizer shall be to-tcao grade, uniform in composition, free flowing and
suitable for application with approved equipment, delivered to the site in bags or other convenient
containers each fully labeled, conforming to the application State fertilizer laws, and bearing the name
and warranty of the producer.
Lime shall be ground limestone containing not less than 85% of total carbonates and shall be
ground to such fineness that at least 50% will pass through a 100 mesh sieve and at least 90% will
pass through a 20 mesh sieve,
Equipment necessary for the proper preparation of the ground surface and for handling all
required materials shall be on hand, in good condition.
Clearing: Prior to grading and tillage operations, the ground surface shall lure cleared of all
heavy vegetation, stumps, stones, roots, cable wire, grade stakes, and any other material which might
hinder proper grading, tillage or subsequent maintenance operations.
Grading: Grades on the areas to be seeded shall be maintained in a true and even condition,
preventing the formation of depressions where water will stand.
Tillage: After the areas required to be seeded have been brought to the grades shown on the
drawings, the areas shall be thoroughly tilled to a depth of at least 6 inches by pbhwing, discing,
harrowing or other approved operations until the condition of the soil is acceptable.
Application of Fertilizer: Fertilizer shall be distributed uniformly at a rate of 4 pounds per
100 square feet on areas indicated to be seeded and shall be incorporated into the soil to a depth of
at least 3 inches by discing. harrowing or other acceptable methods. The incorporation of fertilizer
may be a part of the tillage operation specified above.
Application of lime: Immediately follovvvng and simultaneously'with the incorporation of the
fertilizer, lime shall be distributed uniformly at a rate of 8 pounds per 100 square feet and shall be
incorporated into the soil to a depth of at least 2 inches by discing. harrowing, or other acceptable
methods. The incorporation of the lime with the fertilizer may form a part of the tillaee operations
previously specified.
Leveling: Any undulation or irregularities in the surface resulting from tilla(?e, fertilizing,
liming or other operations shall be leveled out before seeding operations are begun
Seeding: Seeding shall be in accordance with the seeding requirements sho-N71 on the plans.
No seeding shall be done during wundy weather or when the ground is wet or otherwise non -tillable.
The grass seed shall then be covered, using a flexible toothed weeder or other suitable equipment,
by stirring the ground no deeper than 1/4 inch.
Compaction: Immediately after the seed has been planted, the planted areas shall be leveled
and rolled with a culti-packer, roller, or other approved equipment weighing 60 to 90 pounds per
linear foot of roller.
Watering: Immediately following seeding, when necessary to maintain growth of grass and
in any case when planting is permitted in dry weather, planted areas shall be watered. Each watering
shall be in sufficient quantities to obviate rapid drying out and at a rate of which will not cause
erosion.
Protection: The seeded areas shall be protected against traffic or other use by erecting
barricades immediately after seeding is completed and by placing warning signs on the various areas.

MAINTENANCE PLAN
1. All erosion and sediment control practices will be
checked for stability and operation following every
runoff -producing rainfall but in no case less than once
every week. Any needed repairs will be made immediately
to maintain all practices as designed.
2. The sediment basin will be cleaned out when the level of
sediment reaches 2.0 ft. below the top of the riser.
Gravel will be cleaned or replaced when the sediment
pool no longer drains properly.
3. Sediment will be removed from the sediment trap and
block and gravel inlet protection device when storage
capacity has been approximately 50 % filled. Gravel will
be cleaned or replaced when the sediment pool no longer
drains properly.
4. Sediment will be removed from behind the sediment fence
when it becomes about 0.5 ft. deep at the fence. The
sediment fence will be repa,j.red as necessary to maintain
a barrier.
5. All seeded areas will be fertilized, reseeded as
necessary, and mulched according to specifications in
the vegetative plan to maintain a vigorous, deuce

NARRATIVE
Project Description
The purpose of the project is to create an equipment (trucks and construction
equipment) storage area between Market Street and the existing ditch which crosses the
tract. The storage area may be paved at some time in the future. The existing asphalt area
will be extended beside the building. The area north of the existing ditch, which crosses
the tract (32 acres) may be cleared. Prior to the development of this tract a revised
Erosion Control Plan will be provided for review.The total tract is 5.51 acres which ties
north of Market Street (U.S. Highway No. 17) and about 490 feet west of Judges Road
(S.R. No 2127), in New Hanover County.
Site Description
The site has been previously cleared and some minor ditching has been done, as
indicated by the topographic survey and map. The site slopes from elevation 40, at the
southeast comer, to elevation 30 at the intersection of the south bank of the previously
mentioned ditch with the west property line. The area north of the ditch, which is not
planned for development at this time, slopes from the north to the previously described
ditch and has about 8 feet of slope in 560 feet. An existing crossing of the ditch is
evidenced by a 36 inch culvert, which is to he removed. There is an existing one-story
metal building set back about 120 feet from the Market Street right-of-way line. A
portion of the area between the building and Market Street has been paved with asphalt
and/or concrete.
Adjacent Property
The tract on the west side of this property is currently used as an automobile sales
and repair lot. The rear of the car lot (north of ditch) is undeveloped. The tract north of
the portion of the property, which is not planned for development at this time, is a single
family residential development. The area east of the "not planed for development at this
time area" is developed as office/warehouses. The area east of this property, which fronts
Market Street, is a car and truck sales lot.
Soils
The soil types as shown in the "Soil Survey of New I Ianover County, North
Carolina" are "Se" (Seagate) and "Jo" (Johnson).

I II I 1 Definition A temporary fabric barrier placed around a drop inlet.
Purpose To help prevent sediment from entering storm drains during construction opera-
tions. This practice allows early use of the slam drain system.
Conditions Where Where storon drain inlets am to be made operational before pernmanentstabilim-
Practice Applies iron of the disturbed drainage area. This method of inlet protection is effective
where the inlet drains a small, nearly level area with slopes generally less than
5% and where shallow sheet [lows are expected. The immediate land area
around the inlet should be relatively flat (less than I %) and located so that ac-
cumulated sediment can be easily removed.
This practice must not be used near the edge of rill material and must not
divert water over cut or rill slopes.
Design Criteria Ensure that drainage areas do fam exceed I acre per inlet.
Keep the maximum height of fabric above the crest of the drop inlet at 1-5 ft.
This height allows a shallow temporary desilting pool to form behind the fabric
but limits the pressure against the fabric if overtopping occurs. The selected
height of die top of the barrier should allow overflow into the drop inlet and net
let overflow bypass the inlet to unprotected lower areas.
For fabric barriers, use stakes with a minimum length of 3 ft, and space them a
maximum of 3 ft apart, and securely drive them into the ground.
Drive the stakes close to the drop inlet so thatoverflow will fail directly into the
sintvarm, and not on unprotected soil.
To attach the fabric, make a frame around the stakes a maximum of 1.5 ft above
the top of the drop inlet This will serve as a stable crest for overflow during
rainfall.
Ensure that both fabric and supporting stakes are sufficiently strong to hold a
1.5 ft head of water without failure (Figure 6.51a).
Improved performance and sediment storage volume can be obtained by ex-
cavating the area (practice 6.50, ExcawnedDrop Inlet Protection).
Construction 1. As synthetic fabric, use a pervious sheet of nylon, polyester, or ethylene
Specifications ymro x= strength (50 Bill inch minimum}-thatcontains ultraviolet ray in-
hibitors and stabilizers. Fabric should be sufficiently porous toprovide adequate
drainage of the temporary sediment pool. Burlap may be used for short-term ap-
plications. It must be replaced every 60 days.
2. ^tat fabric from a continuous roll to eliminate joints.
3. For stakes, use 2 x 4-inch wood (preferred) or equivalent metal with a min-
imum length of 3 ft.
4. Space stakes evenly around the perimeterof the inleta maximum of 3 ft apart,
and securely drive them into the ground, approximately 18 inches deep.
5. To provide needed stability to the installation, frame with 2 x 4-inch wood
strips around the crest of the overflow area at a maximum of 1.5 ft above the
drop inlet crest.
6. Place the bottom 12 inches of the fabric in a trench and backfill the trench
with at least 4 inches of crushed stone or 12 inches of compacted soil.
7. Fasten fabric securely to the stakes and frame, Joints must be overlapped to
the next stake.
