The Perry Pit operation will provide aggregates for Asphalt
Paving Company's contracts in the northern Denver metropolitan
area and southern Weld County. The materials to be produced from
the property will be suitable for use in concrete, asphalt,
select fill, drain material and road base. Asphalt Paving
Company will operate a portable processing plant on the site,
consisting of a portable cone crusher and a screening/wash plant.
A portable asphalt batch plant will be brought onto the site on a
job-by-job basis. The total acreage of the site is 117.61 acres,
all of which is zoned agricultural.
At present, the property is used as pasture land with some
private hunting use as well. The southwestern portion of the
property appears to have been shallowly excavated at some time in
the past, as the ground level is about two to three feet below
the surrounding land surface. The property does contain some
trees, mainly cottonwoods and willows, along the ditch which
traverses the center of the property. As much as possible, these
trees will be left undisturbed, but it is anticipated that some
of them will need to be removed in the course of mining.
Topographically, the property has very little expression outside
of the Lupton Bottoms Ditch and the South Platte River. Two
power line easements cross the property: one in a north-south
direction on the western portion of the property and one in an
east-west direction on the southwestern portion of the property.
No mining is planned for these easements, although they may be
used for overburden, topsoil, or product stockpiles.
Barrett Energy has a gas well and accompanying facilities on the
property, located north of the proposed asphalt plant site.
Mining will maintain a minimum of 50 foot setback from these
structures. The Lupton Bottoms Ditch that traverses the center
of the property will have a setback of 50 feet from each side of
the ditch edge.
The access road to the mine and plant site will be left after
mining is completed to provide access to the gas well as the
present access will be mined in Phase III. The acreage involved
with this road is not included in disturbance calculations.
The topsoil on the site is about one foot thick with overburden
about three feet thick. Overburden consists of clay and loam.
Sand and gravel underlying the overburden is from 25 to 30 feet
thick. The underlying bedrock consists of shale and claystone.
The depth of ground water is estimated to be about 4 to 5 feet.
