Prior to general stripping topsoil and excavating, install silt fence where indicated. B. Construct erosion control devices where indicated on drawings during rough grading as grading progresses. C. Topsoil must be present to ensure growth. D. Tomporedly seed basin slopes: lepeeil steekpiles, and areas ditluibsd by construction. 1. Seeding times and rotes: a. May 15 to August 15; Annual Ryegross at 40 lbs. /ocre. b. August 15 to November 15; Rye (grain) or wheat at 2 bushels /ocre. c. March 1 to May 15; Oats at 3 bushels /acre. 2. Fertilizer: Commercial onolysis 12/12/12 applied at a rote of 600/ /ocre. a. Apply lime to raise PH to the level needed for species being seeded. b. Work fertilizer and lime into the soil to a depth of 2 -3 IN. 3. All Hydroseeding shall be in accordance with the preceding requirements. 4. Reseed as required until good stand of gross is achieved. 1.2 DURING CONSTRUCTION PERIOD A. Maintain basins, dikes, traps, stone filters, silt fences, etc. B. Inspect regularly especially after rainstorms. C. Repair or replace damaged or missing items. D. After rough grading, sow temporary gross cover over exposed earth areas not draining into o protected device. E. Construct inlets as soon as possible. 1. Install silt fence or straw bole barriers or 1/2" slotted barrel at each new inlet, as necessary to control erosion. F. Provide necessary swoles and dikes to direct water towards a protected device. G. Do not disturb existing vegetation (gross and trees) outside limits of construction. H. Remove sediment from behind silt fences when sediment reaches one- fourth fabric height. I. Topsoil and fine grade slopes and swoles, 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. Grode 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 hove 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 rote 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 gross is achieved. L Products 1. Fertilizer: Commercial analysis 12/12/12 or equivalent applied of a rote of 600 pounds per acre. 2. Lime: Apply agricultural lime to raise PH to the level needed for species being seeded. Soil test may be required to determine rote. 3 S w lee / 51 aP es' Blended mixture of seed shall be applied at rote of 110 p ou n ds per acre. The mix shall consist of 40 pounds Mustang turf -type Toll Fescue. 30 pounds Bonff or Wabash Kentucky Bluegrass, 30 4. Graded areas adjacent to pavement: Blended mixture of seed shall be applied of o rote of 90 pounds per acre. The mixture shall consist of 35 pounds Mustang turf -type Toll Fescue, 30 pounds Fiesta Perenniol. 5. Apply mulch straw at rote of 2 tons per acres immediately after seeding. The straw must be evenly distributed loosely over the entire area. "Slobs 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. .4 MAINTENANCE A. Reseed oil 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. Nointenonce fertilizer - apply 200 1/ or 12 -12 -12 or equivalent.
