PART 3 - EXECUTION

3.1      CLEARING AND GRUBBING

A. Clearing  and  grubbing  shall  be  in  conformance  with  the  SSPWC  Section  300-1.  If potentially hazardous materials are encountered, the Contractor shall stop work in the affected area, and a hazardous material specialist shall be informed immediately for proper evaluation and handling of these materials prior to continuing to work in that area. As  presently  defined  by  the  State  of  California,  most  refined  petroleum  products (gasoline, diesel fuel, motor oil, grease, coolant, etc.) have chemical constituents that are considered to be hazardous waste.

3.2      STRIPPING

A. Prior to beginning any excavation or fill, strip the topsoil to a depth of 6 inches or to a depth sufficient to remove all organic material.   In general, topsoil shall be removed where structures are to be built, trenches dug, and roads, parking lots, walks, and similar improvements constructed within the areas presently covered with topsoil.  Topsoil shall be stored clear of the construction area.   Take reasonable care to prevent the topsoil from becoming mixed with subsoil.   In lieu of reusing stockpiled topsoil, use imported topsoil as required for final grading.
