THIS SHEET TO BE USED
FOR EROSION CONTROL ONLY.
PERSON ONSITE RESPONSIBLE FOR EROSION CONTROL:
DANN SMALL
EQUICOR
PHONE (317)-573-8100
NOTE:
ANY ADDITIONAL EROSION CONTROL MEASURES MAY
BE REQUIRED IN THE FIELD BY THE INSPECTOR.
NOTE:
IF SITE REMAINS INACTIVE FOR A PERIOD OF 2 WEEKS,
THEN STABILIZATION IS REQUIRED TO TAKE PLACE IN
THE FORM OF TEMPORARY SEEDING, MULCH, OR SPRAY
ON PALIMAR.
Seedbed PreDaration for Permanent Seedin
1. Test soil to determine pH and nutrient levels.
Contact you county SWCD or Cooperative Extension
office for assistance and soils information, including
available testing services.)
2. If soil pH is unsuitable for the species to be
seeded, apply lime according to test recommendations.
3. Fertilize as recommended by the soil test. If testing
was not done, consider applying 400-600 lbs/acre of
1 2-12-12 analysis, or equivalent, fertilizer.
4. Till the soil to obtain a uniform seedbed, working
the fertilizer and lime into the soil 2-4 in. deep with
a disk or rake operated across the slope.
The following is a list in sequence of construction
activities to control soil erosion:
1. The contractor shall schedule a Pre-construction
meeting with the Hamilton County Soil and Water
Conservation District prior to any construction on
the site being started.
2. The construction entrance installed.
3. Perimeter Silt fencing to be installed.
4. Maintenance and Refueling area constructed
5. Concrete washout area constructed
6. Posting information area shall be constructed. All
items, as outlined in the in the O&M manual for
Post Constuction water quality measures shall be
placed in this area.
7. Sediment basin for Pond #1 constructed
8. Install outlet pipe for Pond 1. Install blankets
on pond banks and seed were necessary at this
time.
9. Grade the site (sides of swales, mounds and
ponds to be seeded and mulched immediately upon
completion. If the site remains inactive for a
period of 15 days, stabilization is required to take
place in the form of temporary seeding, mulch or
spray on palimar. For temporary seeding, the
contractor shall utilize a fast growing seed of
either oats, annual ryegrass, wheat or rye
depending on time of year. Disturbed areas
should be kept to a minimum at all times.
10. Storm inlets are to be protected immediately
after installation.
11. Contractor 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.
12. 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 or Soil and Water Conservation District.
Payment for additional straw bales shall be at the
contractor's expense. Payment for additional
rip-rap (not shown on plans) and seeding shall be
paid for on a unit basis.
13. Contractor shall install all sanitary sewers, storm
sewers, subsurface drains, and water mains.
Straw bale filters shall be installed at all storm
inlets (including street inlets).
14. Seed all remaining disturbed areas and remove
all BMP's when area is stabilized.
