SECTION 02910 - SOIL EROSION CONTROL SEQUENCE
The following is a list in sequence of construction activities to
control soil erosion:
EROSION CONTROL SEQUENCE
Erosion control must be carried out according to Indiana State Rule
(327 IAC15 -5) referred to as Rule 5 (General Permit for construction
activities storm water Control) administered by Indiana Department, of
Environmental Management, and /or the local Planning Deportment in
the county where construction activities are to commence.
Erosion control activities must begin before commencing construction,
continue thru the construction phase, and maintained following construction
until the area is stable.
Other erosion control measure may be needed during the construction
phase as problems accrue refer to the Indiana Handbook for Erosion Control
in Developing Areas for other measure to meet the requirements of Rule 5.
1. Contractor shall install sediment traps and straw bole
filters, as port of initial phase of any work to insure
maximum silt retention on -site.
2. Moss grade the site (sides of swales, mounds and ponds to be
seeded and mulched immediately upon completion). Temporary
seeding shall be required for all swales and disturbed areas
that cannot be final seeded within a time period that will
prevent slope erosion. For temporary seeding, the
contractor shall utilize o fast growing seed of either oats,
annual ryegross, wheat or rye depending on time of year.
Disturbed areas shall be kept to a minimum at all times.
3. Contoctor shall control mud accumulation on all streets
surrounding project by installing stone surface at all
locations where construction traffic leaves the site. Dust
shall be kept to a minimum by utilizing sprinkling, Calcium
Chloride, vegetative cover, spray on adhesives or other
approved methods.
4. Maintain all filters and traps during construction to
prevent any blockages from accumulated sediment. Additional
seeding and straw boles may be required during construction
as specified by Engineer or Soil Conservation Service. Rip
rap shall be placed in areas of high velocity stream flow
(minimum size 113 cu. ft.). Poyment for additional rip rap
(not shown on plans) and seeding shall be paid for on a unit
basis.
5. Contractor shall install oil sanitary sewers, storm sewers,
subsurface drains, and water mains. Silt barriers shall be
installed at all storm inlets (including street inlets), and
all drainage swales at 100 ft. intervals.
6. All proposed street areas shall be paved as soon as possible
after subgrode is prepared.
7. All disturbed areas shall be seeded and mulched as
specified.
8. Contractor shall maintain all temporary erosion control
measures throughout the construction phase of this project
and remove all temporary erosion and sediment controls only
when there is a sufficient growth of ground cover to prevent
further erosion.
SECTION 02912 - EROSION CONTROL BLANKET
Erosion control blanket shall be a machine- produced mot of 100%
agricultural straw.
The blanket shall be of consistent thickness with the straw
evenly distributed over the entire area of the mot. The blanket
shall be covered on the top side with polypropylene netting
having on approximate 5/8" x 5/8" mesh, and on the bottom with a
polypropylene, netting with on approximate 1/4" x 1/4" mesh. The
blanket shall be sewn together with cotton thread.
Straw erosion control blanket (or low velocity channel lining)
shall be S75 ors manufactured by North American Green, or
equivalent. Erosion control blanket or channel lining shall hove
the following properties.
Material Content:
Straw 100% (.5 lb/sq. yd.) (.27 kg /m2)
Netting One side lightweight photodegrodable
(1 Ib /1000 sq. ft. approx. wt.)
One side heavyweight photodegrodable
(3 Ib /1000 sq. ft. approx. wt.)
Thread Cotton
Physical Specifications (Roll):
Width 6.5 foot (2m}
Length 83.5 foot (25.4m)
Weight 30 Ibs + 10% (13.6 kg)
Area 60 sq. yds. (5Om2)
Site Preparation
- Smooth grade and compact all areas to be covered with mot
- Remove all rocks, dirt clods, gross clumps, trash, and other
obstructions that will lift mat from ground surface.
Anchor Trenches
- The mot 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.
FILE: N: \95330 \20000 \ CAD \ENGR \95330C91
Seeding
- Seed and fertilizer shall be spread before mot installation.
Seed type, fertilizer type, and rote of application shall
comply with seeding specifications.
Mat 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.
Pulling taut may cause mot to bridge depressions in the surface
and allow erosion underneath.
-
Beginning at up or downstream end bury transverse terminal end
of at 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.'
-
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 mot by 3" (min.) and stake... see
"Ground Fastening."
Ground Fastening
Metal pins or wood stakes are recommended for anchoring mat to
the ground surface. Metal pins should be 3/16" diameter steel
with 1 -1/2" diameter steel washer secured at head of pin. Wood
stakes should be 1 "x3" nominal stock cut in a trionculor 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. Core must be taken to assure that
fasteners hold mat securely at the surface and hove sufficient
ground penetration to resist pullout.
- Stake mat to ground on 3 to 5 foot centers. Add extra stokes
at depressions in ground surface where mot 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 of its center and at overlapped edges before backflling
and compacting.
- Stake overlaps longitudinally at 3' intervals.
SECTION 02930 - SEEDING

ultraviolet stabilized.
9. If temporary seeding is established prior to permanent
seeding, the mulch may be eliminated except in "bare" areas.
10. If grading occurs during December, January, or February, no
seeding to take place till spring planting time; however, it
is imperative that all sediment filters and traps are in
place prior to bulk earthmoving or clearing.
11. All areas along street (approximately 25 foot behind curb)
shall be seeded with permament seed mixture as soon as grade
is established. Reseeding may be required after utility
companies have installed their mains.

construction is expected to occur within 60 days, shall be
filled with additional 3" topsoil and seeded with the
temporary seeding process.
13. 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
seasonal 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.
14. All dates shown ore nominal and may be varied with
concurrence of the Engineer or the Local Soil
Conservation Service Office.
