- 10 - <br />• stripping all loose material, topsoil and organic and deleterious <br />materials fran beneath the embankment. <br />No brush, sod, frozen material, or other unsuitable materials or <br />stone of 6 inches or greater should be placed in the fill. The <br />distribution of the material of the fill should he such to avid the <br />formation of lenses or layers of materials differing substantially in <br />character from the surrounding materials. The material should be <br />delivered to the fill surface at a uniform rate and in such quantity <br />as to permit a satisfactory construction procedure. Unnecessary <br />concentration of travel tending to cause ruts or uneven cror~action <br />should be avoided. Before placing the successive layer, all ruts and <br />other hollows mire than 6 inches in depth should be regraded and <br />compacted. After placing the fill material on the fill surface, the <br />material should be spread in horizontal layers. These layers shall <br />not be greater than 8 inches in thickness after compaction. it is <br />recommended a sheepsfoot roller be used for compaction of the <br />embanlanent. The use of hauling and loading equipment for compaction <br />is not reootmnended. <br />The existing embanlrnients at or near the proposed embankment <br />locations should be removed prior to construction of the new <br />structures. Materials removed from the embankments may be reused if <br />they meet the requirements presented above. <br />SAFE"PY EVALOATION <br />Considering the proposed dam heights and subsoils, we have <br />. approached embankment stability analysis on a si~lified basis. <br />
