They eventually <br /> are major components of long-term, permanent stabilization and should <br /> be chosen and planned in conjunction with immediate and long-term <br /> maintenance. The plants should be selected and specified by the design <br /> professional for each individual project. See Practice 6.13 Trees,Shrubs, <br /> Vines, and Ground Covers. <br /> MAINTENANCE <br /> The absence of or an incomplete landscape management specification and/ <br /> or complete maintenance schedule shall constitute grounds for disapproval of <br /> the plans. Proper maintenance is critical for the continued stabilization once <br /> vegetative cover is established. Although maintenance strategies for different <br /> sites may be similar, no two construction sites in North Carolina have been <br /> or will be able to be controlled or protected in identical ways. Variations in <br /> climate,topography,soils,available moisture,size and many other conditions <br /> will dictate the maintenance methodology to be used. A detailed schedule of <br /> maintenance will be required on the plans. This schedule will illustrate how <br /> the initial planting will be maintained to assure immediate, short term and <br /> permanent protection. The schedule will address topics such as appropriate <br /> irrigation of plants during the early establishment phase, drought conditions, <br /> excessive rainfall, mulch replacement, supplemental seeding, supplemental <br /> soils tests, application of nutrients and amendments, control of competitive <br /> and invasive species, disease and insect control, and corrective maintenance, <br /> measures to address failure of vegetation to become established. Contractual <br /> responsibility for maintenance after initial establishment of vegetative cover <br /> will be provided on the plans,in the construction sequence and on the bid list <br /> for the project. Maintenance bonds and/or warranty guarantee may be required <br /> of the responsible party,especially for areas in or adjacent to environmentally <br /> sensitive sites such as wetlands, riparian buffers, floodplains, and waters of <br /> the State. See Example 6.11 a for a sample maintenance specification and a <br /> minimum maintenance check list that shall be provided on all plans. <br /> RECOMMENDED BID LIST <br /> (These items should be itemized on documents utilized to obtain pricing for <br /> planting pertaining to vegetative stabilization of land disturbing projects in <br /> North Carolina.) <br /> • Soil test prior to grading(price per each test). <br /> • Soil test during grading operations(price per each test). <br /> • Soil test at completion of grading and/or prior to seeding, sprigging, <br /> sodding and application of fertilizer, lime, and other soil amendments <br /> (price per each test). <br /> • Ripping/subsoiling to a depth of six(6)inches. (Provide an alternate for <br /> ripping to a depth greater than six(6)inches.) (price per acre) <br /> • Tilling/discing ripped area to a depth of four(4)inches and re-compacting <br /> with a cultipacker roller(include in seeding price). <br /> Rev.5/08 6.11.11 <br />
