805.3CONSTRUCTION —
hours after seeding is completed. Unless otherwise indicated, place only straw or wood fiber over topsoiled areas. Use hay, straw, or wood fiber in other areas, as indicated or specified. Place hay or straw uniformly, in a continuous blanket, at a minimum rate of 1,200 pounds per 1,000 square yards or as otherwise indicated. If directed, increase the rate of application, depending upon the material used, season, soil conditions, or method of application. An acceptable mechanical blower may be used to apply mulch. Do not use machines that cut mulch into short pieces. Anchor mulch with specified mulch binders applied at the following rates:
• Recycled cellulose fiber —160 pounds per 1,000 square yards
805.3(a) 805.3(e)
• Nonasphaltic emulsion —At manufacturer's recommended rate
• Polyvinyl acetate —At manufacturer's recommended rate
• Recycled cellulose fiber/wood fiber mixture —160 pounds per 1,000 square yards
The mulch binder application is incidental to the application of straw and hay mulch. Apply wood fiber mulch hydraulically according to the manufacturer's tank -mixing instructions. It may be incorporated as an integral part of the slurry after the seed and soil supplements have been thoroughly mixed. Apply uniformly at the rate of 320 pounds per 1,000 square yards unless otherwise indicated. Mulch temporary seeded areas with hay.
