This could be accomplished by excavating shallow temporary ditches. <br /> IThe ttenches would not only drain the low-lying aneas, but also would aid in drying out the <br /> soils sumounding these areas. In our opinion, construction of tempotary dreinage ditches <br /> ' prior W major earth�wrk operations would gready improve the general ha�cabiliry of the <br /> site. Tbmpoiary drainage diwhes should be installed as soon as construction begins, and <br /> Iwell in advance of major grading. <br /> I8.4.2.2 Site ratinn <br /> We recommend that trees and brush be cieared and roots and stumps be <br /> Iremaved from buildinB areas, parlanB areas, pavements, and all areas to be graded. The <br /> eaisdng surficial Wpsoil and any soil conhaining signi8cant quan6tics of ocganics should be <br /> � stripped and remo�vad from all amas. The depth of this removal is expected to be variable <br /> over the site. Our explorations encountered from 0 to about 18 inches of surficial topsoil. <br /> iFor estima6ng topsoil stripping quanGdes only, we recommend using an avetage depth of 8 <br /> to 10 inches. Rnots and stumps will likely eztend deeper than the depths estimated above <br /> and should be completely c�emoved in the amas specified abwe. lbpsoil is not considered <br /> � suitable for reuse as swctural SIl and should be removed from the site or stockpiled for <br /> reuse in landscape ac�eas. Stripping and removal of topsoil should extend laterally a <br /> Iminimum distance of 15 feet beyond building limits and parldng and drive areas. <br /> I8.4.2.3 Bm•ldine Pad Pre �ratinn <br /> In addition to stripping the surficial topsoil, stripping of al( �( i Y fill as <br /> I- well as any soft, organic, disturbed or otherwise unsuitable soils (including original topsoil), <br /> I <br /> W-6693-01 <br /> I 15 <br />
