General: Maintain and establish turf by watering, fertilizing, weeding, mowing, trimming, <br /> replanting, and performing other operations as required to establish healthy, viable turf. Roll, <br /> regrade, and replant bare or eroded areas and remulch to produce a uniformly smooth turf. <br /> Provide materials and installation the same as those used in the original installation. <br /> 1. Fill in as necessary soil subsidence that may occur because of settling or other <br /> processes. Replace materials and turf damaged or lost in areas of subsidence. <br /> 2. In areas where mulch has been disturbed by wind or maintenance operations, add new <br /> mulch and anchor as required to prevent displacement. <br /> 3. Apply treatments as required to keep turf and soil free of pests and pathogens or <br /> disease. Use integrated pest management practices whenever possible to minimize the <br /> use of pesticides and reduce hazards. <br /> B. Watering: Install and maintain temporary piping, hoses, and turf-watering equipment to <br /> convey water from sources and to keep turf uniformly moist to a depth of 4 inches (100 mm). <br /> 1. Schedule watering to prevent wilting, puddling, erosion, and displacement of seed or <br /> mulch. Lay out temporary watering system to avoid walking over muddy or newly <br /> planted areas. <br /> 2. Water turf with fine spray at a minimum rate of 1 inch (25 mm) per week unless rainfall <br /> precipitation is adequate. <br /> C. Mow turf as soon as top growth is tall enough to cut. Repeat mowing to maintain specified <br /> height without cutting more than one-third of grass height. Remove no more than one-third of <br /> grass-leaf growth in initial or subsequent mowings. Do not delay mowing until grass blades <br /> bend over and become matted. <br /> 2.11 SATISFACTORY TURF <br /> A. Turf installations shall meet the following criteria as determined by Architect: <br /> 1. Satisfactory Seeded Turf: At end of maintenance period, a healthy, uniform, close stand <br /> of grass has been established, free of weeds and surface irregularities, with coverage <br /> exceeding 90 percent over any 10 sq. ft. (0.92 sq. m) and bare spots not exceeding 5 by <br /> 5 inches (125 by 125 mm). <br /> 2. Satisfactory Sodded Turf: At end of maintenance period, a healthy, well-rooted, even- <br /> colored, viable turf has been established, free of weeds, open joints, bare areas, and <br /> surface irregularities. <br /> B. Use specified materials to reestablish turf that does not comply with requirements, and <br /> continue maintenance until turf is satisfactory. <br /> 2.12 PESTICIDE APPLICATION <br /> A. Apply pesticides and other chemical products and biological control agents according to <br /> requirements of authorities having jurisdiction and manufacturer's written recommendations. <br /> Orange County Solid Waste Drainage Repairs DAA 2200365/TRC 017055.0000.0000 <br /> Drainage Repair Project November 2023 <br /> Orange County, NC 329200-7/8 <br />
