'LI <br />EXHIBIT I (Cont'd) <br />SCS information was found to be applicable to the site and help- <br />ful in designing a topsoil salvage plan. The SCS soil map for <br />the area however was not found to be accurate at the scale <br />examined in the on-site investigation. In places large devia- <br />tions in soil boundaries and depths were readily identified <br />from surface appearance. This is due to differences in examina- <br />tion scale and not an inherent inaccuracy in the SCS ~lat.a. <br />' No chemical or textural data is available from the SCS or <br />other sources. However, plant species on the site clearly <br />' indicate the more important chemical differences, and accurate <br />texture can be determined from the surface because most of the <br />' soils have been extensively cultivated, thereby destroying much <br />of the horizon structure that once existed. <br />Wann sandv loam, 1 to 3 percent slopes (man unit X3B) - <br />I Approximately half the area of the site is occupied by this <br />soil. It is deep and usually rather poorly drained even though <br />a sandy loam. It is derived from sandstone and shale. Permeabil- <br />I ity is moderately rapid and available water capacity is high. <br />Although salinity and alkalinity is the second lowest of all <br />I the soils on the site, the native vegetation still included <br />saltgrass, Alkali Sacaton and other species that exhibit <br />I fairly high salt/alkali tolerance. On this site all of this <br />soil was cultivated at one time or another, and some of it is <br />currently under cultivation. Therefore, its original structure <br />has been totally lost because of plowing. Drill logs show an <br />average depth to gravel of about 3.5 feet with a range of 0.5 <br />-30- <br />
