Contractor shall Install sediment traps and straw bale filters, as shown. 2. Grade the site (sides of swales, mounds and ponds to be seeded and mulched Immediately upon completion). Temporary seeding shall be recommended for all awales 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 dl times. 3. 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. 4. 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 Contractors expense. Payment for additional rip rap (not shown on plans) and seeding sholl be paid for on a unit basis. 5. Contractor shall install am sanitary sewers, storm sewers, subsurface drains, and water mains. Straw bale filters shall be Installed at oil storm inlets (including street Inlets). Recommended Erosion Control Measures Erosion Control Blanket: Recommend erosion control blankets such as North American Green S150 be Installed as a temporary erosion control measure in the bottom of any swole with a concentrated surface water flow. Refer to erosion control practice number 3.17 . Straw Bale Drop Inlet Protection: Recommend using straw bale drop Inlet protection as per erosion control practice number 3.54 as a temporary erosion control measure until blankets are installed. Other drop inlet protection practices may become necessary upon the recommendation of the engineer or erosion control consultant if a specific need arises during construction. Topsoil Salvage and Utilization: As per erosion control practice number 3.02. Removal of topsoil to a depth of six inches (or more if required by the engineer) from all areas to be excavated or filled. Topsoil should be stored at a location where it will not Interfere with construction operations. Temporary Seeding: Recommend temporary seeding as per erosion control practice number 3.11 if disturbed ground is to be left bare for two months or more. In addition, it is recommended red clover be added to the seeding mixture at a rate of 10 pounds per acre. Dormant and Frost Seeding: As per practice number 3.13 attached to be applied if necessary. Surface Roughening: As per erosion control practice number 3.03, suggest using a bulldozer to track with cleats perpendicular to the slope of slopes on disturbed ground of six percent or greater and around the shore of the lakes as a temporary measure until ready for blankets. Temporary Gravel Construction Entrance/Exit Pod: Recommended as per erosion control practice number 3.01. Tree Con servatlon/Protection: As per erosion control practice number 3.83, the contractor shall, at the dlrection of the developer, endeavor to save and protect trees of value and worth which do not impair construction of Improvements as designed. In the event cut or fill exceeds 0.5 foot over the root area, the developer shall be consulted with respect of protective measure to be taken, if any, to preserve such trees. Maintenance Schedule: Maintenance of all erosion control practices should be done as needed on a weekly basis and after all large storms. A construction supervisor should be assigned the task of seeing that all practices are installed and maintained according to the design criteria. Maintenance for each erosion control practice should be conducted per maintenance schedule shown on each erosion control practice job sheet (attached). Construction Sequence Schedule: Spring (Projected season to start): Locate areas of tree protection, install gravel construction entrance, install temporary silt fence, strip and stockpile topsoil. Excavate building areas and other earthwork (lakes, roads, swales, sewers, etc.) Spring/Summer: Install strowbole Inlet protection. Install rock chute outlet protection. Install temporary erosion control blankets as needed. Track in ridges with dozer cleats on all slopes greater than six percent and around side slopes of lakes. Summer/Fall: Apply sod in all areas that are finish graded. Apply temporary seeding in areas where earthwork construction Is halted and area will be bare and exposed for more than two months. Maintain erosion control practices as per erosion control maintenance schedule above. Remove temporary erosion control measures In stabilized areas that have been sodded. Winter/Spring: Apply dormant seeding on any areas that show a need for it. Continue maintenance of existing erosion control practices. Spring/Summer/Fall (following year): Stabilize all open ground and remove temporary erosion control practices. Implement find landscape plan. FORMS\18545ECM Seeding Specifications: I. Ditch Banks: shall be seeded and covered with North American Green fiber blanket /S/50 and /SC150 (or Equal) or Hydroseeded with straw mulch. The Contractor shall follow the manufacturer's recommended guidelines for Installation and staple patterns when Installing the fiber blankets. Seeding rate: I10#/acre or 2.5#/1000 S.F. Seeding mixture: 38% Kent. 31 Fescue 19% Perennial Rye 19% Annual Rye 14% Orchard Gross 10% Kent. Bluegrass 2. 4' of topsoil (minimum) shall be placed prior to permanent seeding. 3. If grades ore established between May 15 and August 10, a temporary seeding consisting of 40/ of Annual Ryegrass shall be planted per acre. 4. If grades ore established between October 15 and December 30, either Rye (grain) or Wheat may be used at the rate of 2 busheis/Ac. All grains should be mowed prior to seed maturing. 5. If temporary seeding is established prior to permanent seeding, the mulch may be eliminated except In 'bare' areas_ 6. If grading occurs during December, January, or February, use dormant seeding and it should be done within 7 days of last land disturbing activity.

AFTER A YARD IS RE -VEGETATED, REMOVE ALL TEMPORARY EROSION CONTROL MEASURES ALL AREAS NOT DENOTING PERMANENT SEEDING OR FIBER BLANKETS SHALL BE TEMPORARILY SEEDED. RECOMMENDED EROSION CONTROL MEASURES WERE TAKEN FROM CHAPTER 3 AS STATED IN THE INDIANA HANDBOOK FOR EROSION CONTROL IN DEVELOPING AREAS. ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY INSPECTOR AS CONDITIONS WARRANT. Maintenance: Seeding *Inspect periodically, especially after storm events, until the stand is successfully established. (Characteristics of a successful stand include: vigorous dark green or bluish—green seedlings; uniform density with nurse plants, legumes, and grasses well inter—mixed; green leaves; and the perennials remaining green throughout the summer, at least at the plant base.) *Plan to add fertilizer the following growing season according to soil test recommendations. *Repair damaged, bare, or sparse areas by filling any gullies, re— fertilizing, over— or re—seeding, and mulching. *If plant cover is sparse or patchy, review the plant materials chosen, soil fertility, moisture condition, and mulching; then repair the affected area either by over—seeding or by re—seeding and mulching after re—preparing the seedbed. *If vegetation fails to grow, consider soil testing to determine acidity or nutrient deficiency problems. (contact your SWCD or Cooperative Extension office for assistance.) *If additional fertilization is needed to get a satisfactory stand, do so according to soil test recommendations. Maintenance Storm *Inspect after storm events to check for movement of mulch or for erosion. *If washout, breakage, or erosion is present, repair the surface, then re—seed, re—mulch and, if applicable, install new netting. *Continue inspections until vegetation is firmly established. Maintenance Blankets *During vegetative es;,- )lishment, inspect after storm events for any erosion below the blanket. *If any area shows erosion, pull back that portion of the blanket covering it, add soil, re—seed the area, and re—lay and staple the blanket. After vegetative establishment, check the treated area periodically. METES/23899 2"-3" WASHED STONE 12'-0" MIN.
