a RECLAMATION PLAN <br /> Quarry Floor = 6 to 7 inches <br /> South and West Facing Slopes = 10 to 11 inches <br /> Quarry Outlet area = 4.5 to 5.5 inches <br /> Expanding on this worst case scenario, if the south end of Stage 2 is mined then there will <br /> be significant amounts of additional soil available. That soil can be used to upgrade soil depths on <br /> previously topsoiled lands that are growing poorly because of inadequate depth and to topsoil other <br /> disturbances that have not been previously topsoiled. It is important to note that the available soil in <br /> the south end of Stage 2, although generally of greater quality and depth, is considerably less than <br /> the volume available in Stage 1. <br /> (The figures presented above are derived from a computer model of the topsoiling process <br /> and is based upon measured acreages. It is assumed that the topsoil salvage will be consistent with <br /> the respective salvage depths as indicated on the soil profiles presented in Soils Information - <br /> Exhibit 1.) <br /> Revegetation <br /> The central direction of the revegetation plan is two-fold. First, is to establish good grass <br /> growth necessary to control erosion, especially on the quarry side slopes. Second, is to provide a <br /> suitable invasion environment so trees and shrubs can readily invade the revegetated area. The seed <br /> mixtures for the grasses is based upon the species typically found in the potential vegetation <br /> associated with typical soils in the area. A limited amount of introduced grass species are also used <br /> to help establish rapid cover, but the amount of these species is kept to a minimum so as to allow <br /> for an open community that will trend toward dominance by native species as well as allow for <br /> invasion of native species from the surrounding areas. <br /> Planting of this site follows a typical pattern for a semi-arid environment. Seeding should <br /> only occur between late August and early October OR between January and late March. <br /> Seeding during these times will provide for the greatest success. Spring seeding tends to produce <br /> the maximum number of seedlings while autumn and winter seeding produces fewer seedlings but <br /> similar cover and density as that achieved by spring seeding followed by early summer die-back as <br /> a result of excessive competition. The ultimate vegetation produced by both methods is usually <br /> similar, although compositional variations may occur depending on moisture patterns during the <br /> first growing season. <br /> Due to the fact that the soils will probably be fairly rocky, broadcast seeding will probably <br /> be required. Drill seeding might be done, but would be hard on equipment. <br /> The mixtures designed for this operation do not require fertilization or mulching to succeed. <br /> No irrigation is necessary. <br /> No trees will be planted on this site. The invasion rate of trees into this site, as evidenced by <br /> invasion into past disturbances, is very high. This pattern is also evident for many of the native <br /> shrubs. Growth rates of woody vegetation, once established, is also high. <br /> The following seed mixture is based on broadcast rates of approximately 90 live seeds per <br /> square foot. Seeding should occur within 7 to 10 days of topsoil distribution, provided topsoil <br /> distribution occurs during the planting season. In the event the topsoil is spread during a time when <br /> seeding cannot occur, the topsoil surface should be extensively loosened prior to seeding, especially <br /> Table Mountain Quarry - Castle Concrete Company Exhibit E Page E-6 <br />
