EXHIBIT I (Cont'd) <br /> <br />there are small, highly localized areas where saline and <br />alkaline conditions are found as evidenced by the presence of <br />saltgrass. However, such sites are few, small and highly dis- <br />persed. These tiny pockets of saline/alkaline soil appear to <br />be similar to the Arvada loam and may represent outliers of <br />that soil. <br />In most areas, 8 to 15 inches of soil could be salvaged, <br />but a few spots are very thin and stony where the gravel bed <br />approaches the surface or actually outcrops. These are small <br />and of little consequence. <br />Halaquepts, nearly level (map unit SIV) - In the north- <br />eastern corner of the site is found a soil which should be <br />strictly avoided in any salvage operations. This is the <br />Halaquepts soil. Even the name indicates its terrible chemistry. <br />Hala indicates it is a saline soil, and quepts means it is <br />very wet. In the area where this soil occurs, salvageable <br />topsoil is actually in a minority quantity and for the most part <br />should be avoided completely. <br />The Halaquepts is a poorly-drained, salt-affected soil <br />that is highly variable in texture, depth and structure. The <br />upper two feet ranges from a loam to a clay. On this site the <br />depth ranges from 0.5 feet to as much as 7 feet, and the texture <br />can change from a gravelly sandy loam to clay in a matter of a <br />few feet horizontally. <br />About 10 percent of the area occupied by this soil is <br />severly alkaline and saline, even to the extent that Distichlis <br />stricta has a difficult time surviving. About 70 percent of <br />-32- <br />
