shall be removed by Contractor.
4. Maintain all filters and traps during construction to prevent
any blockages from accumulated sediment. Additional
seeding and straw bales may be required during construction as
specified by Engineer, Soil Conservation Service or Owner. Rip -
rap shall be placed in areas of high velocity stream flow
minimum size 1/3 cubic feet). Payment for additional rip -rap
not shown on plans) and seeding shall be paid for on a unit
basis as approved by Owner's representative.

SECTION 02912 - EROSION CONTROL BLANKET
Erosion control blanket shall be a machine -produced mat of 100%
agricultural straw.
The blanket shall be of consistent thickness with the straw
evenly distributed over the entire area of the mat. The blanket
shall be covered on the top side with polypropylene netting
having an approximate 5/8" x 5/8' mesh, and on the bottom with a
polypropylene netting with an approximate 1/4* x 11,C mesh. The
blanket shall be sewn together with cotton thread.
Straw erosion control blanket (or low velocity channel 'lining)
shat[ be S75 as manufactured by North American Green, or equina
lent. Erosion control blanket or channel lining shall have the
following properties.
A. Material Content:
Straw 100% (0.5 Ib/sq. yd.) (0.27 kg/m2)
Netting One side lightweight photodegradable
(1 Ib/1000 sq. ft. approx. wt.)
One side heavyweight photodegradable
(3 lb/1000 sq. ft. approx. wt.)
Thread Cotton
B. Physical Specifications (Roll):
Width 6.5 feet (2m)
Length 83.5 feet (25.4m)
Weight 30 lbs + 10% (13.6 kg)
Area 60 sq. yds. (50m2)
Site Preparation
• Smooth grade and compact all areas to be covered with mat.
• Remove all rocks, dirt clods, grass clumps, trash and other
obstructions that will lift mat from ground surface.
Anchor Trenches
• The mat must be anchored at the upstream and downstream ends of
the protected area and intermittently in between.
• Excavate end trenches to a minimum of 12" deep and 6" wide
before placing mat.
• Dig intermittent check slots 6' deep by 6" wide transverse to
mat at approximately 25' intervals.
Seeding
• Seed and fertilizer shall be spread uniformly before mat in-
stallation. Seed type, fertilizer type, and rate of opplica-
tion shall comply with seeding specifications.
Mot Placement
• Unroll mat flat side against the ground. Unroll mat in
direction parallel with direction of water flow.
• Mat should lay flat. DO NOT PULL MAT TAUT over ground.
Putting mat taut may cause mat to bridge depressions in the
surface and allow erosion underneath.
• Beginning at up or downstream end, bury transverse terminal end
of mat to secure and prevent erosion flow underneath.
• Fold and secure mat snugly into all transverse check slots.
• Backfill and compact trenches and check slots after staking the
mat in bottom of trench ... see 'Ground Fastening', below.
• Bury final terminal end as prescribed above.
• Overlap roll ends by 3' (min.) with upslope mat on top to
prevent uplift of mat end by water flow.
• Overlap adjacent edges of mat by 3" (min.) and stake ... see
"Ground Fastening', below.
Ground Fastenin
Metal pins or wood stakes are recommended for anchoring mat to
the ground surface. Metal pins should be 3/16" diameter steel
with 1-11f diameter steel washer secured at head of pin. Wood
stakes should be 1" x 3" nominal stock cut in a triangular
shape. Stakes should be 9' to 18' long depending on soil
density. Longer anchors are required for loose soils.
Note that ground fasteners different from those mentioned here
may function adequately. Care must be taken to assure that
fasteners hold mat securely at the surface and have sufficient
ground penetration to resist pullout.
• Stake mat to ground on 3 to 5 foot centers. Add extra stakes
at depressions in ground surface where mat bridges over to
assure ground conformity.
• Drive wood stakes to within 3" of ground surface. Do not drive
flush to surface. Steel or plastic pins should be driven
flush
to surface.
• In all transverse terminal trenches and check slots, stake each
mat at its center and at overlapped edges before backfilling
and compacting.
• Stake overlaps longitudinally at 3' intervals.
SECTION 02930 - SEEDING
1. Scope of Work
To reestablish vegetative cover by seeding, either perma-
nent/temporary or erosion control types, as shown on the
Plan. After finish grading, All construction areas are to
be seeded.
2. Sodding (Alternate): Locally grown Bluegrass blend uniform
in color, type, density, and thickness. Whenever possible,
rolls of sod shall be used - not slabs of sod.
3. Permanent Seeding: March 1 to May 15 and August 10 to
October 15. (Dates may vary at discretion of Landscape
Architect depending on weather conditions.)
A. SwalsZSlopes: Blended mixture of seed shall be ap-
plied at the rate of 110 pounds per acre. The mixture
shall consist of 40# Mustang turf -type Tall Fescue, 30#
Banff or Wabash Kentucky Bluegrass, 30# Flesto Perenni-
al Ryegrass and 10# Redtop Bentgrass.
B. Graded Area Ad.�acent to Pavement: Blended mixture of
seed shall be applied at the rate of 90 pounds per acre.
The mixture shall consist of 35# Mustang turf -type Tall
Fescue, 30# Fiesta Perennial Ryegross and 25# Banff or
Wabash Kentucky Bluegrass.
4. Temporary Seeding:
A. May 15 to August 15; 40#/acre Annual Ryegrass.
B. August 15 to November 15; 2 bushels/acre Rye (grain) or
wheat. (May be dormant seeded between December 10 and
February 28. Add 50% to seed quantity.)
C. March 1 to May 15; 3 bushels/acre Oats.
5. Erosion Control Seeding: An interim seeding to be applied
to all disturbed areas as soon as final grade is established.
Mix and apply as shown on detail sheet.
(Note: If this seeding is applied immediately on finish
grading, it can save some of the further seeding and
lengthen the duration between maintenance of silt traps and
barriers and street cleanings.)
6. Fertilizer. Commercial analysis 12/12/12 applied at a rate
of 600#/acre. Apply lime to raise PH of soil to level needed
for species being seeded. Work fertilizer and lime into the
soil to a depth of 2-3 inches. (PH factor should be checked
prior to seeding. Lime should not be required if topsoil is
replaced.)
7. All Hydroseeding shall be In accordance with the preceding
requirements.
8. Mulch: Wood cellulose fiber may be used where application
Is made by hydraulic mulching at the rate of one ton per
acre. Straw mulch may be used and applied uniformly in
a continuous blanket at the rate of 2 tons per acre within
24 hours after seeding in accordance with Section 621 of
IDHSS.
9. Sediment Control Fabric: Fabric shall be non -woven con-
striction composed of polypropylene and shall be ultra-
violet stabilized.
10. If Temporary seeding and/or erosion control seeding is
established prior to permanent seeding, the mulch may be
eliminated except in 'bare" areas.
11. If grading occurs during December, January, or February,
dormant seeding procedures shall be used. It is imperative
that all sediment filters and traps are in place prior to
bulk earthmoving or clearing operations commencing.
12. All areas along street (approximately 25 feet behind curb)
shall be seeded with permanent seed mixture as soon as
grade is established. Reseeding may be required after
utility companies have installed their mains. If erosion
control seeding is established, the permanent seeding can
be delayed until lot is improved.
13. All lots/ouhots where grading has occurred and no
construction is expected to occur within 60 days, shall be
filled with additional 3" of topsoil and seeded with the
erosion control seeding process.
14. During dry weather, keep lawns watered with sprinklers or
other approved methods. Reseed any areas not germinating or
damaged at intervals as may be required according to Season-
al condition. Water grass and execute necessary weeding until
acceptable and full stand of grass has been obtained Upon
acceptance by the Owner, the Owner shall assume maintenance
of the lawn areas.
15. All dates shown are nominal and may be varied with concur-
rence of the Engineer, Landscape Architect, Local Soil Conserv-
ationist or Owner.
