Thia opin- ion ie based upon the scope of development ae we underatand it, and the expectation that the criteria and proceedurea aet forth in the following sectiona will be Pollowed. Slo�e Stabilitv We are confident that the naturally occurring slope soila are in a stable condition� and that distress which would in- volve theae soils is highly unlikely. The lottg term stabil- ity of the uncontrolled Yill soils covering the natural slope face is leas certain. However, at the time o£ our study in- dicationa of impending or past large scale distreas were not observed , in the fill soils. A moderate to high auscsptibility to water erosion is dieplayed by the fill soils. The existing average Pill slope angle of 36° is most probably at or elightly above the angle of repose for theae soils in a looae condition. In our opinion the beat approach for treating the preaent slope condition would include dressing of the slope face so that a conaistent, uniform condition and a maximum grade of 1 1/2 to 1 (horizontal to vertical) is established. In addi- tion� . seeding or planting should be accomplished so as to • establiah a good ground cover. Alteration of the slope by filling, terracing, or other pro-
