Assign an on -site person with the daily responsibility and authority to ensure that erosion /sediment control practices are installed according to this sequence schedule. 2. Contact Indiana Underground Planned Protection Systems, Inc. "Holey Maley for underground Utility locations. (1- 800 382 -5544) 3. Before opening up the site, first evaluate, mark and protect important trees and associated root zones, unique areas to be preserved (i.e. wetlands), or existing vegetation suitable for use as filter strips (especially in perimeter areas). 4. Install silt fence around the perimeter of the site as shown. 5. Install an adequate and stable construction entrance exit drive from the construction site to keep mud and sediment off public roads. Dust shall be kept to a minimum by utilizing sprinkling, Calcium Chloride, vegetative cover, spray on adhesives or other approved methods. 6. Identify construction staging area, material storage area, concrete washout areas, dumpster area. Each area shall properly protected and delineated prior to construction. 7. Prior to the start of construction activities, pump down the water level of the existing pond to two feet below normal pool elevation. This will aid in preventing turbid water from entering the storm sewer system. Repeat this step following all rain events once the pond has settled. If rain events persist to the point of turbid water reaching the outlet, stormwater clarification additives are to be used (Floc Log by Applied Polymer Systems, Inc. or approved equal). Follow manufacturer's instructions. 8. Once erosion and sediment control measures are in place, begin land clearing followed immediately by grading. Do not leave large areas unprotected for more than 7 days. 9. Start mass earthwork including topsoil striping and stockpile. 10. Start building pad and road grading. 11. As the grading progress, install fabric inlet bafflers to storm inlets, and additional silt fencing to prevent sediment from going off site or into the retention pond. 12. Install the main runoff conveyance system with inlet and outlet protection devices to convey storm runoff through the site without creating gullies and to prevent damage to open channels. Sides of Swales, mounds and ponds to be seeded and mulched upon completion. Temporary seeding shall be required for all swales and disturbed areas that can not be final seeded within a time period that will prevent slope erosion. For temporary seeding, the contractor shall utilize a fast growing seed of either oats, annual rye grass, wheat or rye depending on time of year. Disturbed areas shall be kept to a minimum at all times. 13. As soon as the storm drain system is functional, install drain inlet protections, which trap sediment on -site in shallow pools while allowing high water flows to enter the system. 14. Install sanitary sewers and other utilities. 15. Complete roadway and parking lot grading followed by aggregate layers and curbing. 16. Immediately after grading, apply surface stabilization practices on all graded areas, using permanent measures in accordance with the erosion control plan. However, if weather delays permanent stabilization, temporary seeding and /or mulching may be necessary as a stop -qap measure. Also stabilize (using temporary seeding /mulching or other suitable means) any disturbed area where active construction will not take place for 15 working days. 17. After construction and final grading, landscape and permanently stabilize all disturbed sites, including borrow and disposal areas. Also remove temporary runoff control structures and any unstable sediment around them, and vegetate those areas. 18. Maintain all erosion and sediment control practices until all disturbed areas are permanently stabilized.

Assign an on -site person with the daily responsibility and authority to ensure that erosion /sediment control practices are installed according to this sequence schedule. 2. Contact Indiana Underground Planned Protection Systems, Inc. "Holey Maley for underground Utility locations. (1- 800 382 -5544) 3. Before opening up the site, first evaluate, mark and protect important trees and associated root zones, unique areas to be preserved (i.e. wetlands), or existing vegetation suitable for use as filter strips (especially in perimeter areas). 4. Install silt fence around the perimeter of the site as shown. 5. Install an adequate and stable construction entrance exit drive from the construction site to keep mud and sediment off public roads. Dust shall be kept to a minimum by utilizing sprinkling, Calcium Chloride, vegetative cover, spray on adhesives or other approved methods. 6. Identify construction staging area, material storage area, concrete washout areas, dumpster area. Each area shall properly protected and delineated prior to construction. 7. Prior to the start of construction activities, pump down the water level of the existing pond to two feet below normal pool elevation. This will aid in preventing turbid water from entering the storm sewer system. Repeat this step following all rain events once the pond has settled. If rain events persist to the point of turbid water reaching the outlet, stormwater clarification additives are to be used (Floc Log by Applied Polymer Systems, Inc. or approved equal). Follow manufacturer's instructions. 8. Once erosion and sediment control measures are in place, begin land clearing followed immediately by grading. Do not leave large areas unprotected for more than 7 days. 9. Start mass earthwork including topsoil striping and stockpile. 10. Start building pad and road grading. 11. As the grading progress, install fabric inlet bafflers to storm inlets, and additional silt fencing to prevent sediment from going off site or into the retention pond. 12. Install the main runoff conveyance system with inlet and outlet protection devices to convey storm runoff through the site without creating gullies and to prevent damage to open channels. Sides of Swales, mounds and ponds to be seeded and mulched upon completion. Temporary seeding shall be required for all swales and disturbed areas that can not be final seeded within a time period that will prevent slope erosion. For temporary seeding, the contractor shall utilize a fast growing seed of either oats, annual rye grass, wheat or rye depending on time of year. Disturbed areas shall be kept to a minimum at all times. 13. As soon as the storm drain system is functional, install drain inlet protections, which trap sediment on -site in shallow pools while allowing high water flows to enter the system. 14. Install sanitary sewers and other utilities. 15. Complete roadway and parking lot grading followed by aggregate layers and curbing. 16. Immediately after grading, apply surface stabilization practices on all graded areas, using permanent measures in accordance with the erosion control plan. However, if weather delays permanent stabilization, temporary seeding and /or mulching may be necessary as a stop -qap measure. Also stabilize (using temporary seeding /mulching or other suitable means) any disturbed area where active construction will not take place for 15 working days. 17. After construction and final grading, landscape and permanently stabilize all disturbed sites, including borrow and disposal areas. Also remove temporary runoff control structures and any unstable sediment around them, and vegetate those areas. 18. Maintain all erosion and sediment control practices until all disturbed areas are permanently stabilized.
