Verification of conditions: Prior to commencing the finish grading, review the installed work of <br />other trades and verify that their work is complete. <br />1. Rough Grading: Grading in planting areas (except raised planter areas) shall be <br />established to within plus or minus 0.10 foot prior to beginning of finish grading. <br />D. Import topsoil only when necessary to supplement site soil to achieve grades shown on <br />drawings, or if site soil is unsuitable for planting. <br />3.2 PREPARATION <br />E. Weeding: Before finish grading, weeds and grasses shall be dug out by the root or sprayed with <br />an herbicide and disposed of off-site. This procedure is outlined under the Landscape Planting <br />Section. <br /> <br />F. Debris: Remove stones and debris 1 inch in diameter and greater and clumps of earth that do not <br />break up.
