Seeding rate: 50# /acre Seeding mixture: 100% perennial rye. 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. Silt fencing for entire project 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. Grade the site (sides of swales, mounds and ponds to be seeded and mulched immediately upon completion). Temporary seeding shall be recommended 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 ryegrass, wheat or rye depending on time of year. Disturbed areas should be kept to a minimum at all times. 8. Storm inlets are to be protected immediately after installation. 9. 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. 10. 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 Conservation Service. 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. 11. 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). Curb inlet NEM Temporary straw bale dam to be removed during blanket installation. Stone bags shall be placed around curb inlets. Silt Sack shall be used for inlets in inverted Crown Conditions. Imo Silt Fence NOTES: Seedbed Preparation for Permanent Seeding 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 12 -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. ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY THE HAMILTON COUNTY SURVEYOR'S OFFICE.
