uence of Construction for StormwaterQ_ualit
The stabilized construction entrance and filter inlet protection for existing storm inlets and pipes shall be installed
prior to beginning other earth disturbing activities.
Perimeter protection, silt fences, diversion berms /swales, rock filters, also shall be installed prior to starting other
earth disturbing activities.
Whenever possible, erosion and sediment control measures shall be constructed and installed prior to performing
other earth disturbing activities.
Minimize erosion from exposed areas by providing and maintaining temporary or permanent stabilization measures.
Erosion control measures to protect exposed areas shall be installed at the end of the day's work or within 24
hours of the completion of the earth disturbing activity, as applicable for the type of measure.
All disturbed areas shall be seeded and /or stabilized upon completion of the earth disturbing activity.
All seeded areas shall be stabilized per the Specifications. Seeded and planted areas shall be stabilized with an
anchored, crimped or tockified mulch and seed mixture.
All graded areas, (lawns, basins, swales, etc.) with slopes equal to or steeper than 6H:1V shall be stabilized with
an erosion control blanket per the Project Specifications. Constructed landscaping mounds shall be stabilized with
an erosion control blanket. Soil stockpiles shall be seeded and mulched to minimize erosion.
Areas to be paved shall be stabilized with a temporary stone cover. The temporary stone stabilization shall be
equivalent to the proposed stone sub -base material. Adequate sub -base depths shall be maintained during
construction and provided prior to final paving. Stone stabilization shall be installed per the paving specifications
and details.
Install pipe and grate inlet protection measures and pipe outlet protection as new pipes or pipe extensions are
installed. Limit excavation to the work that can be performed that day. Trenches shall be seeded and mulched
as part of the backfill operation.
Wrap all grates with filter fabric to prevent debris and sediment from entering storm system. Check weekly and
after each storm event for debris and sediment. Clear blockages as identified. Torn or damaged fabric shall be
replaced.
Temporarily seed and stabilize all disturbed areas where work will cease for 5 days or longer.
Erosion and sediment control measures shall be maintained until the area of the Work is 95% stabilized

Inspect silt fence periodically (weekly) and after each storm event.
If fabric is torn or damaged or in any way becomes ineffective, replace
the affected portion immediately.
Remove deposited sediment when it reaches half the height of the fence,
or it is causing the fabric to bulge.
Take care not to undermine the fence during sediment removal.
After the contributing area has been stabilized, remove the fence and
remaining sediment, bring the disturbed area to grade, and stabilize.

Installation:
1. Cut fence fabric from a single roll to eliminate joints. Use a minimum overlap 2' if
a joint is needed.
2. Bury 12` of fence fabric per the Silt Fence Section Detail, this sheet.
3. Space support evenly, with a maximum spacing of 3'.
4. Supports shall abut the inlet perimeter where ever possible.
Provide a 4' bed of no. 2 stone where overflow falls to unprotected soil.
5. Prefabricated welded wire structures are acceptable.
Maintenance:
1. Inspect fence periodically (weekly) and after each storm event.
2. If fence is damaged, repair or replace it immediately.
3. Remove deposited sediment when it reaches one third of the height of fence.
4. Take care not to undermine the fence during sediment removal.
5. After the contributing area has been stabilized, remove the fence and remaining
sediment, bring the
disturbed area to grade, and stabilize.
6. Replace the fence with Gravel Donut (Practice 3.56) if it continually sustains
significant damage.

General Erosion and Sediment Control Notes
1. All erosion and sediment control practices shall be in accordance with the Indiana Handbook for Erosion Control
in Developing Areas from the Division of Soil Conservation, Indiana Department of Natural Resources.
2. A copy of this Erosion and Sediment Control Plan and the Erosion and Sediment Control Report shall be available
at the Project Site throughout the entire construction period.
3. The Contractor shall control waste, garbage, debris, wastewater, and other substances on the site so they will not
be transported from the site by the action of wind, storm water runoff, or other forces. Proper disposal or
management of all wastes and unused building material appropriate to the nature of the waste or material is
required.
4. Public or private roadways shall be kept clear of accumulated sediment. All sediment that is cleared must be
returned to the likely point of origin or other suitable location. Clearing of large amounts of sediment shall not
include flushing the area with water.
5. Minimize the exposure of bare earth by limiting the work area to that necessary to perform the Work, and by
proper scheduling of manpower and equipment.
6. All erosion and sediment control measures shall be inspected, cleaned, and maintained following each storm
event.
7. Wherever possible, maintain existing vegetative cover. Use non - vegetative material including mulch, erosion
blankets, or stone to control erosion from disturbed areas.

2. Reshape as needed for drainage and runoff control.
3. Topdress with clean stone as required. Maintain minimum depth through construction.
4. Immediately remove mud and sediment tracked or washed onto public roads by
sweeping or brushing.
5. Repair any broken pavement immediately.
