Thece �i1Cs and sands were con- <br /> solidated under ice during the glaciation and Uecame compact and hard. In <br /> our opinion soils underlying the site are stxble, and poten:ial large slide <br /> of the site is not likely to occur unless thesc material.s are exposed to water <br /> ' and 6ecome saturated. <br /> Along the slope� these campact allts and sands are exposed to weathering. <br /> When these soils become saturated, the strenKth of soil masa Siminishes. <br /> 'I'hecefore sloughiaz or slabUing of these materials ha, occurrad from time tu <br /> time. Sloughing and slabbing can be minir.!ized by properly protecting the <br /> expoaed eurface from becoming saturated. <br /> 5ince we were only engaged in visual examic�ation of the site our opinion i� <br /> derived on haais of what we found and from our expericnce in deulin� witli <br /> �lacially overconsolidated soile in thic :i.cea. <br /> 7`GW Aseociatea� Inc. <br /> / <br /> en H�W B-i f��_��or"''I----., <br /> Principal ( <br /> c . .. <br /> � J <br /> � <br /> � <br /> J <br /> � <br />
