No clearing shall be performed until written permission is given by MANAGER and until the <br />CONTRACTOR has provided construction staking for the proposed work. Clearing shall consist of <br />cutting brush to the ground level, removing such material, along with wood, rubbish, tree stumps, <br />and any other vegetation with roots in excess of 1-inch diameter, and other deleterious materials, and <br />disposing of all such material in the accepted manner described below. <br />C. In areas designated to be stripped of unsuitable or objectionable material, said materials shall be <br />stripped to the full depth of organic or other unsuitable material as determined by MANAGER and <br />CERTIFYING ENGINEER, whichever is greater. <br />D. Stripped and grubbed vegetation shall be removed and disposed in stockpiles or other approved <br />methods in an area designated by MANAGER. <br />3.02 TOPSOIL REMOVAL: <br /> Topsoil is defined as an acceptable growth medium as approved by MANAGER and CERTIFYING <br />ENGINEER that has no chemical or physical characteristics, which will exclude its use as such. <br />A. Stripping of the topsoil shall be done within the entire area of the stripping limits. <br />B. CONTRACTOR shall excavate and remove topsoil in a manner that will minimize contamination <br />with other soil horizons, and will take such measures as are necessary to ensure that the removal of <br />topsoil does not result in erosion or excessive sedimentation. <br />C. CONTRACTOR shall stockpile topsoil at locations designated by MANAGER. Stored topsoil <br />shall not be disturbed by mining, leaching operations, or construction activities, and shall be <br />protected from wind and water erosion, compaction, and contamination. <br />D. CONTRACTOR shall grade topsoil stockpiles to prevent erosion and ponding of precipitation in <br />the stockpile areas. The maximum topsoil stockpile height will be approved by MANAGER. The <br />CONTRACTOR shall protect stockpiled topsoil by an effective cover of non-noxious, quick- <br />growing, annual, and perennial plants, approved by MANAGER, which shall be seeded or planted <br />during the first appropriate growing season after removal. <br />3.03 WASTE REMOVAL: <br /> Waste material is defined as material too wet, too dry, frozen or containing ice or snow, containing organic or <br />other deleterious matter, having poor characteristics of grading or compaction, having other characteristics that <br />may result in undesirable settlement or other movement of the fill, or within the fill, or otherwise not meeting <br />the requirements of the SPECIFICATIONS, provided that this definition permits drying, water, and any other <br />processing or reprocessing to make the material stable and suitable prior to incorporating it into the fill as <br />permitted in the SPECIFICATIONS or by the MANAGER and CERTIFYING ENGINEER. <br />A. CONTRACTOR shall excavate and remove waste in a manner that will minimize contamination <br />with other soil horizons. <br />B. CONTRACTOR shall stockpile removed waste at locations designated by MANAGER.
