RE: Geological Mineral Resources for the Filly ridge PUD at State Highway
52 and Weld County Road 3 1/4, Weld County, CO.
To Whom It May Concern:
The proposed area is located within the Colorado Piedmont section of the
Great Plains physiographic province. The Colorado Piedmont, formed
during the Late Tertiary and Early quaternary time (approximately
2,000,000 years ago), is a broad, erosional trench, which separates the
Southern Rocky Mountains from the High Plains. Structurally, the site lies
along the western flank of the Denver Basin. During the Late Mesozoic
and Early Cenozoic Periods (approximately 70,000,000 years ago), intense
tectonic activity occurred, causing the uplifting of the Front Range and
associated down warping of the Denver Basin to the east. Relatively flat
uplands and broad valleys characterize the present-day topography of
the Colorado Piedmont in this region.
No mineral resources were found on this site at the depths explored, the
soils encountered at the site are Sandy Clay (SC) to a depth of 13 feet,
then Sandstone to a depth of 25 feet, followed by Clay-stone. If is our
opinion that the small nature of the site, 23.88 acres would prevent the site
from being considered an economic deposit of minerals if found at
greater depth. The project site is located in Seismic Risk Zone 1 of the
Seismic Zone Map of the United States as indicated by the 1997 Uniform
Building Code.
