NUMBER: 09-019 FILE NUMBER: SHEET NO, OF 2 TURFING SCHEDULE: C1. All disturbed areas shall be dressed to typical sections and plowed to a depth of 5 inches. The top two inches shall be pulverized to provide a uniform seedbed Note: Lime should be applied with necessary equipment to give uniform distribution of these materials. The hand -bucket method is not acceptable. 02, The following are rates and kinds of these materials to be applied PER ACRE: Select temporary AND permanent seed mixture based upon the dates of seeding.

Ground Agricultural Limestone 40001bs. Sept. 1-Oct. 31 or Feb. 15-Apr, 30 03, Seeded area shall be cultipacked to firm seedbed and to cover seed. 04 Grain straw shall be applied over seeded areas as mulch. No bare ground shall be visible in the mulched area if proper application is achieved. Thick clumps of straw are not permissible as uniform coverage is expected. Straw shall be applied at a minimum of 4,000 lbs. per acre. 05 The mulched area shall be tacked with liquid asphalt sufficient to hold straw in place where necessary. OFF. Ditch treatment shall be used in areas where steep grades could cause ditch erosion. Use of jute mash, excelsior matting, or fiberglass roving is acceptable Ditch treatment should be installed before mulching operation. 07. Temporary ground cover on exposed slopes shall be seeded, fertilized and mulched sufficient to restrain erosion within 21 calendar days of completion of any phase of grading, 08, Permanent groundcover sufficient to restrain erosion should be provided on all areas disturbed during this project within 15 working days or 90 calendar days.. whichever period is shorter, following completion of construction. MAINTENANCE SCHEDULE 01. Ail erosion and sediment control practices will be checked for stability and operation following every storm event, but in no case less than once every week. Any repairs or cleaning necessary to maintain erosion and sediment control practices shall be completed immediately. 02. Ali seeded areas will be re -fertilized, re -seeded as necessary, and mulched according to the Turfing Schedule. NOTE: ALL DISTURBED AREAS SHALL BE SEEDED ACCORDING TO THE TURFING SCHEDULE. ANY AREAS WITHOUT ESTABLISHED GROUND COVER AFTER 90 DAYS SHALL BE RESEEDED AND REFERTILIZED. GRAPHIC SCALE a 10 0 5 10 20 40 m ( IN FEDT ) 1 inch = 10 ft. 305 N.
