• convex slopes. Soil salvage in this map unit may yield slightly less than predicted. <br />Map unit 98H occurs on mesa side slopes that are not as steep as those found in map unit <br />98B. Hardness of bedrock varies depending on the underlying strata. Wahweap soil has the <br />same physical and chemical properties as those soils similarly named in the survey area. <br />Wahweap is outside the range of characteristics compared to the survey area, in that it <br />occurs in an area of 7 inches mean annual precipitation. <br />Table 2.04.93 represents average depths and pH of lift layers for soil salvage materials in <br />the 1998 survey area and which lies in the proposed future area of disturbance. Weighted <br />average lift depth is based on the percent of each soil component including inclusions for <br />each map unit. Appendix 2.04.9-9 lists the percent composition for each soil type in a map <br />unit. Weighted average lift depths are used to calculate volume of salvage material in table <br />2.04.9-4. Lift layer one is a combination of the following horizons where present: A, Ap, Ag, <br />AB, AC, Bw, and Bt if the pH of those horizon was less than 8.0. Lift layer two is a <br />combination of the following horizons where present: AC, Bw, and Bt if the pH of those <br />• horizons was greater than 8.0 and Bk, Btk, and C horizons. <br />Table 2.04.9-4 represents the acreage by map unit and the weighted average volume (cubic <br />yards) of soil salvage material by lift layer available in the 1998 soil survey area and which <br />lies in the proposed future area of disturbance. Soil map unit 986 and 98H are combined <br />into one lift layer for all horizons as sited in 2.05.4(2)(d). <br />(Revised 2/00) 2.04.9-14 <br />
