EXHIBIT I—SOILS INFORMATION
Soils within the entire property consist of four soil types. The area within the
proposed permit boundary is composed of three soil types. Soil types Aquolls
and Aquents, Cascajo Gravelly Sandy Loam, and Otero Sandy Loam constitute
the area to be mined.
Soil types mapped within the proposed permit boundary can be found on the
soils map contained within this Exhibit.
Aquolls and Aquents are formed in recent alluvium. It is a deep, poorly drained
soil that is typically found in low-lying areas with the water table being very close
to the surface layer. The capability classification by the United States
Department of Agriculture, Soil Conservation Service (SCS) and excerpts from
the Soil Survey of Weld County (SCS, 1972) are contained in this Exhibit. The
SCS capability classifications for this soil indicate that, due to wetness, they are
severely limited in their suitability for cultivation. However, Aquolls and Aquents
are typically supportive of rangeland and wildlife habitat.
Cascajo Gravelly Sandy Loam is a deep, excessively drained soil formed in very
gravelly alluvium, between slopes of 5 and 20 percent. It is typically found on
upland ridges and knobs. The SCS capability classifications for this soil type
indicate that it is not easily cultivated, but is a fair medium for re-establishing
rangeland.
Otero Sandy Loam is a deep, well drained soil that is formed in alluvium and
eolian deposits between slopes of 5 to 9 percent. It is typically found on plains
and terraces. The SCS capability classifications for this soil type indicate that it
has limited suitability for cultivated crops and is capable of supporting extensive
wildlife habitat.
