Erosion and Sediment Control Notes

1. All erosion and sediment control measures are to be constructed and maintained in accordance with the Illinois Urban Manual, latest edition.

2. All erosion and sediment control measures shall be installed prior to the start of any construction or disturbance of the site. The measures may have to be adjusted to meet field conditions during construction. Any measures, in addition to those outlined in the plans and which are deemed necessary by the village, shall be implemented immediately by the developer.

3. Regular inspection and maintenance of all erosion and sediment control measures must be provided by the developer. Inspections should occur weekly, and after any rainfall greater than 1/2". Any non-functioning sediment control measures or damaged devices that are found during inspection shall be repaired or replaced immediately The developer shall be responsible for any sediment which leaves the property, and the developer is also responsible for maintenance of all sediment control measures until the site is permanently stabilized.

4. All points of construction ingress and egress shall be protected to prevent tracking of debris, dirt, and mud onto adjacent streets, parking lots, or properties. Any debris, dirt, or mud that reaches an improved public right-of-way, street, or parking area shall be promptly removed, and transported to a proper disposal area.

5. All sediment must be prevented from entering any public or private storm drainage system. Reusable inlet filter baskets (Flexstorm, CatchAll, or equivalent), sediment basins, and water filtering bags, shall be provided as needed.

6. All drainage swales shall be sodded. Areas or embankments having slopes steeper than or equal to 3H:1V, and approved by the village, shall be stabilized with sod, matting, or erosion blanket in combination with appropriate seeding.

7. Topsoil stockpiles shall be located to avoid erosion of stockpile onto neighboring properties or into restored project areas. Stockpiles shall be located so that a drainage swale is located between the stockpile and any downstream properties. If a stockpile is to remain in place for more than 14 days, it must be seeded and blanketed to minimize soil erosion by both wind and water.

8. The developer is responsible for obtaining a separate National Pollution Discharge Elimination System (NPDES) permit from the Illinois Environmental Protection Agency whenever 1 acre or more of property is disturbed. For developments over 1 acre, the developer must also prepare and maintain a Storm Water Pollution Prevention Plan (SWPPP) at the project site, along with the NPDES permit. For developments less than 1 acre, a Sediment and Erosion Control Plan must be maintained by the developer.

9. Disturbed areas shall be stabilized with temporary or permanent measures within 14 calendar days of the end of active hydrologic disturbance, or redisturbance.

10. If dewatering services are used, adjacent properties and discharge locations shall be protected from erosion. Discharges from construction dewatering shall be routed through an effective sediment control measure such as a sediment trap, a sediment basin, or any other appropriate measure.
