OUTLET CONTROL DETAIL
Control Measures:
1- All work will be done in accordance with the State of North
Carolina Sedimentation and Erosion Control Act. No land disturbing
activity beyond that required to install the appropriate erosion
control measures may proceed until measures are approved
by the State of North Carolina.
2. Following site clearing, all storm drainage culverts and
structures shall be installed. Rock inlet Sediment Traps shall be placed
around all drainage structures to Collect surface runoff and
control siltation and release water at a gradual rate.
J. Parking lots shall have stone base placed on them for
stabilization and shoulders shall be seeded to stabilize the
soil. Seed bed preparation shall be conducted according to North
Carolina Deportment of Transportation Standard Specifications for
Roads and Structures (D.O. T.). The ground surface shall be
cleared of stumps, stones, roots, cables, wire, grade stakes, and
other materials that might hinder proper grading, tillage,
seeding or subsequent maintenance operations. Grades on the area
to be seeded shall be maintained in a true and even condition.
Maintenance shall include any necessary repairs to previously
graded areas. All graded areas shall be thoroughly tilled to a
depth of at least four (4) inches by plowing, disking, harrowing,
or other approved methods until the condition of the soil is
acceptable. On sites where soil conditions are such that high
cloy content and excessive compaction cause difficulty in getting
clods and lumps effectively pulverized, the Contractor shall use
the rotary tillage machinery until the mixing of the soil is
acceptable and no clods or clumps remain larger than 1 112 inches
in diameter. A firm and compact seed bed is required and after
being graded, the seed bed shall be lightly compacted with a land
roller, such as a cultipacker, before and after seeding.
Limestone shall be dolomitic agriculture ground limestone
containing not less than 10 percent magnesium oxide. Lime shall
be uniformly applied at the rate of 2 tons per acre. Fertilizer
shall be uniformly applied at a rate of 500 pounds per acre of
10-20-20 analysis. The fertilizer shall be incorporated into the
upper three or four inches of prepared seed bed Pst prior to the .
last tillage operation, but in no case shall it be applied more
than three days prior to seeding. Fertilizer shall be used
immediately after delivery or stored in a manner that will not
permit it to harden or destroy its effectiveness
When hydroseeding equipment is used for seeding, fertilizer
shall be applied simultaneously with seed, using the above rates
of application. Seed shall be certified seed or equivalent based
on North Carolina Seed improvement Association requirements for
certification. All seed shall be furnished in sealed standard
containers. Seed which has become wet, moldy, or otherwise
damaged prior to seeding will not be acceptable Seeding shall
be accomplished with hand planters, power —drawn planters, hand
packers, or hydroseeding equipment at the following rates.
Seed Bed Preparation (Offsite drainage easements and
stormwater detention area).
Lime — 2 tons per acre
Fertilizer 00-20-20) — 500 pounds per acre
Seeding Mixture:
(January 1 — March 31)
Common Bermuda grass (unhulled) — 20 pounds per acre
(April 1 — July 31)
Common bermudagrass (hulled — 15 pounds per acre
Weeping Lovegrass — 5 pounds per acre
Centipede — 8 pounds per acre
(August 1 — December 31)
Common Bermuda grass (unhulled) — 15 pounds per care
Tali Fescue -- 120 pounds per acre
Centipede — B pounds per acre
Seed Bed Protection:
Straw Mulch — 2 tons per acre (visual)
Asphalt Tack — 0.03 gallons per square yard
4. Temporary seeding will be done in those areas that ore bare
and no work done for more than 15 days but in no case shall
the area be left unattended for more than 120 days.
5. All erosion and sedimentation control devices shall be
inspected by the Contractor after each rainfall. When
inspection reveals the trap to be reduced to 5OZ of design
capacity or the device to be deficient in its intended
purpose such as fabric deterioration for silt fences the
Contractor shall restore the device to its original
condition.
6. All erosion and sedimentation control devices shall remain
in place and be maintained by the Contractor until all
seeding is established and construction areas have been
stabilized.
