Do not broadcast or drop seed when wind <br /> velocity exceeds 5 mph (8 km/h). <br /> 1. Evenly distribute seed by sowing equal quantities in two directions at right angles to <br /> each other. <br /> 2. Do not use wet seed or seed that is moldy or otherwise damaged. <br /> 3. Do not seed against existing trees. Limit extent of seed to outside edge of planting <br /> saucer. <br /> B. Sow seed at rates indicated. <br /> C. Rake seed lightly into top 1/8 inch (3 mm) of soil, roll lightly, and water with fine spray. <br /> D. Protect seeded areas with erosion-control mats where indicated on Drawings; install and <br /> anchor according to manufacturer's written instructions. <br /> E. Protect seeded areas with slopes not exceeding 1:6 by spreading straw mulch. Spread <br /> uniformly at a minimum rate of 2 tons/acre (42 kg/92.9 sq. m) to form a continuous blanket 1- <br /> 1/2 inches (38 mm) in loose thickness over seeded areas. Spread by hand, blower, or other <br /> suitable equipment. <br /> 1. Anchor straw mulch by crimping into soil with suitable mechanical equipment. <br /> 2. Bond straw mulch by spraying with asphalt emulsion at a rate of 10 to 13 gal./1000 sq. <br /> ft. (38 to 49 L/92.9 sq. m). Take precautions to prevent damage or staining of structures <br /> or other plantings adjacent to mulched areas. Immediately clean damaged or stained <br /> areas. <br /> 2.7 HYDROSEEDING <br /> A. Hydroseeding: Mix specified seed, commercial fertilizer, and fiber mulch in water, using <br /> equipment specifically designed for hydroseed application. Continue mixing until uniformly <br /> blended into homogeneous slurry suitable for hydraulic application. <br /> 1. Mix slurry with nonasphaltic tackifier. <br /> 2. Spray-apply slurry uniformly to all areas to be seeded in a one-step process. Apply slurry <br /> at a rate so that mulch component is deposited at not less than 1500-lb/acre (15.6- <br /> kg/92.9 sq. m) dry weight, and seed component is deposited at not less than the <br /> specified seed-sowing rate. <br /> 2.8 SODDING <br /> A. Lay sod within 24 hours of harvesting unless a suitable preservation method is accepted by <br /> Engineer prior to delivery time. Do not lay sod if dormant or if ground is frozen or muddy. <br /> B. Lay sod to form a solid mass with tightly fitted joints. Butt ends and sides of sod; do not stretch <br /> or overlap. Stagger sod strips or pads to offset joints in adjacent courses. Avoid damage to soil <br /> or sod during installation. Tamp and roll lightly to ensure contact with soil, eliminate air <br /> Orange County Solid Waste Drainage Repairs DAA 2200365/TRC 017055.0000.0000 <br /> Drainage Repair Project November 2023 <br /> Orange County, NC 329200-5/8 <br />
