After rough grading, sow temporary grass cover over exposed earth areas not draining into a protected device. E. Construct inlets as soon as possible. 1. Install silt fence or straw bale barriers or 1/2" slotted barrel at each new inlet, as necessary to control erosion. F. Provide necessary swales and dikes to direct water towards a protected device. G. Do not disturb existing vegetation (grass and trees) outside limits of construction. H. Remove sediment from behind silt fences when sediment reaches one - fourth fabric height. 1. Topsoil and fine grade slopes and swales, etc. Seed and mulch as soon as possible in areas as they become ready. 1.3 NEAR COMPLETION OF CONSTRUCTION A. Eliminate erosion control devices except inlet protection. B. Grade to finished or existing grades. C. Fine grade remaining earth areas disturbed by construction activities. D. Topsoil must be a minimum of 4" to ensure growth. F. Permanent seed: March 1 to May 15 and August 10 to October 15. (Dates may vary at discretion of Landscape Architect depending on weather conditions.) G. Soil Preparation. 1. Soil surface must be free of rocks, debris• and other foreign materials. 2. Soils must have proper moisture control to assure proper germination and growth. 3. Soil surface must be compacted to a depth of at least 6 inches. 4. Soil preparation depends on soil conditions at time of seeding. Various tools may be necessary to achieve surface finish. 5. Surface of soil shall be level and large voids eliminated to applying fertilizer, lime and seed. H. Applying fertilizer, lime and seed. 1. Work fertilizer and lime Into soil to a depth of 2 - 3 Inches. 2. Apply seed carefully and cover seed with 1/4 Inch soil, apply seed carefully and avoid covering seed more than 1/4 Inch. 3. Apply mulch at rate of 2 tons per acre following seeding. 4. Water as necessary to ensure adequate moisture for germination and growth. 5. Reseed as necessary until a good stand of grass Is achieved. I. Products 1. Fertilizer. Commercial analysis 12/12/12 or equivalent applied at a rate of 600 pounds per acre. 2.

The mix shall consist of 40 pounds Mustang turf -type Tall Fescue, 30 pounds Banff or Wabash Kentucky Bluegra 4. Graded areas adjacent to pavement: Blended mixture of seed shall be applied at a rate of 90 pounds per acre. The mixture shall consist of 35 pounds Mustang turf-type Tall Fescue, 30 pounds Fiesta Perennial 5. Apply mulch straw at rate of 2 tons per acres immediately after seeding. The straw must be evenly distributed loosely over the entire area. "Slabs" of straw must be redistributed or It will, kill young seedlings. On large open areas the mulch must be secured to soil by a tack or mechanical means to prevent wind action on mulch. 3.4 MAINTENANCE A. Reseed all areas that don't take. B. Apply a maintenance fertilizer (•) within 6 months of acquiring a good stand. C. Avoid traffic on area until area is well protected and stable. D. Water as necessary to ensure adequate growth and development. •Maintenance fertilizer - apply 200 Ibs of 12 -12 -12 or equivalent. -1�h NO SCALE L TYPICAL SWALE DETAIL TENTATIVE SCHEDULE Activities Erosion and Sediment Control Sequence 1.

Contact Indiana Underground Planned Protection Systems, Inc. ( "Holey Moley ") for underground Utility locations. (1- 800 - 382 -554) 3. Before opening up the site, first evaluate, mark and protect important trees and associated root zones, unique areas to be preserved (Le. wetlands), or existing vegetation suitable for use as filter strips especially in perimeter areas). 4. Install sediment basins or traps around the perimeter of the site and diversions above the site to direct water from undisturbed areas away from the sediment traps while conveying sediment- laden runoff from disturbed areas to the traps. 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. 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 cannot 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. 7. 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. 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. As grading progresses, install additional traps, silt fences, slope drains, temporary diversion:., and other runoff control measures at appropriate locations to keep sediment contained on -site. 10. Immediately after grading, apply surface stabalization 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 30 working days. 11. 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. PROJECT INFORMATION 1A. PROJECT LOCATION MAP: See Sheet C100 1B.
