Re: Mineral and Aggregate Evaluation
131/2 Acre Bates Development
Weld County, Colorado
Terracon Project No. 21995110
Terracon has completed a mineral and aggregate evaluation for the proposed residential
development to be located southwest of the intersection of Weld County Roads 31 and 76,
northwest of Eaton, Colorado.
The purpose of the evaluation was to provide information relative to:
• subsurface soil conditions, and
• presence or absence of economic deposits of sand, gravel, coal, limestone or quarry
rock.
The information contained in this report is based upon the results of test borings, a literature
search, and our general knowledge of the soils and geology of the site.
The subject site is approximately 131/2 acres in size, and is located northwest of Eaton,
Colorado. The site is currently an agricultural field that is vegetated with alfalfa. Drainage is
fair to the west. The property is bordered to the west by the Eaton Ditch. An old residence
that is currently in a state of disrepair is located on the southern end of the property.
The proposed area is located within the Colorado Piedmont section of the Great Plains
physiographic province. The Colorado Piedmont, formed during 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 near
the axis of the Denver Basin. During the Late Mesozoic and Early Cenozoic Periocs
(approximately 70,000,000 years ago), intense tectonic activity occurred, causing the uplifting
of the Front Range and associated downwarping of the Denver Basin to the east. Relative,y
flat uplands and broad valleys characterize the present-day topography of the Colorado
Piedmont in this region.
The site ,is underlain by the Cretaceous Laramie Formation. The Laramie consists of
interbedded sandstone, siltstone and claystone units. Minor coal deposits are locally observed

in the Laramie at this location. The Laramie is overlain by valley fill deposits of Pleistocene
and/or Holocene Age.
Horizon Construction Services, L.L.C. drilled five (5) test borings on the property on September
11, 1998. The borings were drilled to depths of approximately 20 feet. Based on the test
borings that were spaced essentially uniform across the site the general soils encountered
included clayey sand and sandy silty clay that is underlain by claystone and siltstone bedrock
at depths ranging from approximately 1 foot to 15 feet. The test borings recorded a thin lense
of coal in boring 3 at a depth of approximately 19% feet.
Based on the borings and our knowledge of the area, it is Terracon's opinion that economic
deposits of sand and gravel, limestone, or quarry rock are not present in the soils or bedrock at
the proposed development. The Laramie Formation is known to contain major coal deposits in
the Boulder-Weld Coal Field in southern Weld County. The coal encountered in boring 3 does
not appear to be thick enough or of great enough areal extent to be considered an economic
deposit. Terracon is not aware of any coal deposits or coal mining operations associated with
the Laramie Formation in the immediate vicinity of the development. Therefore, it is our opinion
that economic mineral and aggregate deposits are not present within the proposed 13% acre
Bates Development.
The scope of services for this project does not include either specifically or by implication any
environmental assessment of the site or identification of contaminated or hazardous materials
or conditions. If the owner is concerned about the potential for such contamination. other
studies should be undertaken.
This report has been prepared for the exclusive use of our client for specific application to the
project discussed and has been prepared in accordance with generally accepted geotechnical
engineering practices. No warranties, either express or implied, are intender or made. In the
event that changes in the nature, design, or location of the project as outlined in this report,
are planned, the conclusions and recommendations contained in this report shall not be
considered valid unless Terracon reviews the changes, and either verifies or modifies the
conclusions of this report in writing.
