SCOPE
This report presents geological data, interpretation, and evaluation which pertains to
the development of the proposed subdivision Red Baron Estates in Weld County, Colorado.
The subdivision is a proposed 123.5-acre development located east of the Town of Fort
Lupton in Weld County, Colorado. More particularly, the site is located in the SE''A of
Section 30, and the E% of the E%z of Section 31, Township 2 North, and Range 65 West of
the 6th P.M., Weld County, Colorado.
The intent of this subdivision is to provide lots for residential development.
I
SITE INVESTIGATION
This investigation was carried out by means of site inspection by the author of this
report, evaluation of test hole data from High Plains Engineering Preliminary Subsurface
Investigation and Foundation Recommendations (Job #02-2920), and information obtained
from "Sand, Gravel, and Quarry Aggregate Resources—Colorado Front Range Counties",
'1 "Guidelines and Criteria for Identification and Land Use Controls of Geologic Hazard and
Mineral Resource Areas" and " Proceeding of the Fifteenth Forum on Geology of Industrial
Minerals" by the Colorado Geological Survey, "Geological Map of Colorado" by the
U.S.G.S. and "Soil Survey of Weld County, Colorado Southern Part", by the U.S.D.A. Soil
Conservation Service. Information on economic constraints for sand and gravel mining were
from verbal communications with local gravel pit operators.
GEOLOGY
Regional and Local Settings
The site lies in the Colorado Piedmont section of the Great Plains Physiographic
Province. The Colorado Piedmont is an elongated trough in the Great Plains, adjacent to the
Front Range of the Southern Rocky Mountains. The Colorado Piedmont was formed when
.l uplift of the area in Miocene-Eocene times (20 to 50 million years ago) produced and
increase of stream erosion resulting in scouring next to the foothills and outlying areas. The
r
1,' 1
Piedmont is bordered by the Southern Rockies to the west, Great Plains Enscarpment to the
northeast, and Palmer Divide to the south.
a
More particularly, the site lies on the western edge of the Denver Basin, a thick
accumulation of sediments involved with down-warping in the basin area and uplift of the
!� adjacent highland areas in late Cretaceous and early Cenozoic. Small anticlinal folds occur
adjacent to the Front Range in the sedimentary rocks and are conductive to the accumulation
of oil and gas deposits. The closest known fault to the site is approximately 10 miles to the
west, or one mile east of the Town of Frederick, Colorado. The fault is believed to be
inactive since no recent records of fault movement or earthquakes exist.
Slopes at the site are slight (0.5% to 4.0%) with drainage flowing to the east with a
maximum slope of approximately four percent (4%). The site is not located within the 100-
1 year or 500-year floodplain. Groundwater levels are below a depth of fifteen feet (15'),
which was the maximum depth obtained during drilling.
a
Economic Geology
Mineral resources at the site do not exist. Test hole data reveals that no pit run was
encountered. The mineable area of the site was determined to be approximately 0 acres.
Based on the above data and criteria used in determining economic feasibility of local gravel
operations, we feel that the site is not large enough, and does not contain enough gravel to be
economic for mining. Information on oil and gas deposits at the site were not available at this
time; however, oil and gas wells are located near this area.
I
Potential Geologic Hazards
Geologic hazards caused by gravity, such as landslides, rock falls, mud and debris
flows, and snow avalanches are not anticipated in the present state of the site. Utility
trenches may require shoring or bracing in order to create safe working conditions during
construction.
The SCS described the soils at the site as 1) Olney Loamy Sand (1 to 3% slopes), 2)
Valent Sand (0 to 3% slopes), and 3) Valent Sand (3 to 9% slopes). These soils are described
by the SCS as having 1) moderate permeability, slow surface runoff, and low erosion hazard;
2
I
V
2) rapid permeability, slow surface runoff, and low erosion hazard, and 3) rapid permeability,
Islow surface runoff, and low erosion hazard; respectively.
The soils, which are to support foundations, are sand, sandy clays, and clays with a
Islight expansion potential (less than 0.5%) or a consolidation potential (less than 2.2%). Each
building site should have a complete geotechnical investigation and engineered foundation so
Ias to minimize the effects of structures on the expansive soils.
I
GROUNDWATER RESOURCES
IPotable water is to be supplied by individual wells for each lot. Shallow groundwater
at the site should not be used as potable water, but may be used for irrigation water pending
Iacceptable water tests and well permits. Pollution of the groundwater caused by individual
sewage disposal systems at the site should not exist because each site will have its own septic
Ifield designed per the I.S.D.S.R. for Weld County.
I
SEWAGE DISPOSAL
IEach house site in the subdivision will have its own septic field designed per the
I.S.D.S.R. for Weld County.
ISUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
IThe site is not underlain with pit run, and therefore, is not economical to mine. Oil
and gas wells are located in the region although sufficient information was not obtainable to
Idetermine the economic feasibility for oil and gas production at the site. Soil expansion, soil
consolidation, and potential trench caving are hazards which will require attention prior to
Iand during the construction process.
Potential hazards can be minimized or eliminated by 1) a geotechnical investigation
being performed for each building site and following the recommendations in the report, and
2) following current construction codes.

Based on the data mentioned in this report, we feel that the site is suitable for the
proposed subdivision provided the recommendations in this report are met. This report does
not reflect any variations in surface and subsurface conditions either natural or manmade.

PURPOSE:
This report reflects a preliminary "blanket-type" soils investigation from soil
borings to determine the subsurface soil identification, and to determine the
physical characteristics of the soil. The recommendations contained in this
report are based upon the results of field and laboratory testing, engineering
analysis, and experience with similar soil conditions.
LOCATION AND SITE CONDITIONS:
This report represents the results of the data obtained during the subsoil
investigation at the Red Barron Estates P.U.D., being a part of the SE1/4 of
Section 30, and the E1/2 of Section 6, T2N, R65W of the 6th P.M., Weld
County, CO.
The site is presently vacant land. This large parcel appears to have gently
rolling topography, with slopes of 0.5% to 4.0%.
SUBSOIL CONDITIONS:
Four, four-inch diameter holes were drilled to a depth of fifteen feet at the
building site on January 28, 2003, as shown on the attached site map.
Samples of the soil were taken at two-foot intervals. These samples were
analyzed in the field and laboratory to determine the characteristics of the
soil for identification and foundation design. In general, the soil profiles in
the five test holes did not vary to a considerable degree, as the attached
profile hole logs indicate. The Standard Penetration Test similar to ASTM
D1586 showed a range of 10 - 16 blows for 12-inch penetration, at a depth
of 4 feet and a range of 10 - 15 blows for a 12-inch penetration at a depth of
9 feet. No free water was encountered during the drilling operation.
One-dimensional swell/consolidation tests were performed on selected
samples to evaluate the expansive, compressive and collapsing nature of the
soils and/or bedrock strata. These tests indicated a consolidation potential of
0.7% to a consolidation potential of 2.2% at a depth of 4 feet and a
consolidation potential of 1.2% to an expansion potential of 0.4% at a depth
of 9 feet. Please review the individual hole sample data and corresponding
soil boring hole location log. The soils in this report were classified using
the American Society of Testing Materials (ASTM) procedures.
•
SUBSURFACE ANALYSIS:
Based on the geotechnical engineering analysis, subsurface exploration and
laboratory test results, all of the test holes represented a low consolidation
potential.
It appears that the majority of the lots with low-moderate consolidating soil
types would be founded on spread footings with allowable soil bearing
capacities of approximately 1000 psf to 1500 psf at 4 foot depths and 1250
psf to 1500 psf at 9 foot depths.
FOUNDATION DRAIN:
The drainage system should be lined with a 10 mil plastic liner, which will
contain a 4-inch diameter perforated drainpipe (rigid perforated PVC pipe is
recommended) encased in a minimum of 8-inches deep by 12-inches of
clean, %-inch to 11/2-inch river rock. The drain should extend around the
lower level of the footing perimeter with the invert at the high end of the
drain being placed a minimum of four-inches below the bottom of the
footing. The drain should be run to a non-perforated sump pit with a lift
pump and a high water alarm, or provide a free gravity outlet to the surface,
at a minimum slope of 1/8 inch per foot to facilitate efficient removal of
water, (1/4 inch per foot is desired). The river rock should be placed a
minimum of 8 inches over the pipe for the full width of the trench. The top
of the gravel should be covered with Mirafi 140 N filter fabric or equivalent,
to minimize clogging of the river rock and perforated pipe by backfill
material.
To help prevent secondary damage that could be caused by slab movement,
the following construction techniques are additional recommendations for
the foundation construction.
SLAB ON GRADE CONSTRUCTION:
1. Where slabs-on-grade are chosen and the owners are willing to accept
the risks associated with slab movement, the following
recommendations should be followed:
a.) Positive separations and/or isolation joints should be provided
between slabs and all foundation walls, columns and utility lines.
Isolation may be achieved with 1/2 inch isolation material or by
sleeving.
b.) Eliminate under slab plumbing where feasible. Where such
plumbing is unavoidable, it should be pressure tested during
construction to minimize leaks, which would result in wetting of
the sub soils.
c.) Place the slab directly on the undisturbed natural soils, or well
compacted fill soil. Floor slabs and footings should not be
constructed on frozen subgrade. Slabs should be reinforced with
rebar, wire mesh or fiber mesh to help control crack separation.
2. Provide frequent scoring of the slabs to provide joints for controlled
cracking of the slab. Control joints should placed to provide
approximate slab areas of 150 square feet. The depth of sawed
control joints should be 'A of the slab thickness.
3. Proper drainage away from the foundation walls should be provided.
A minimum slope of 12 inches in the first 10 feet out from the
building is recommended. Roof downspouts and sill cocks should
discharge into long concrete splash blocks (5 feet long) or into metal
gutter extensions to deposit runoff water beyond the limits of the
backfill soil near the foundation walls. Sprinkling systems should not
be installed or direct water within 10 feet of the foundation.
The foundation and retaining walls should be well cured, damp
proofed, and well braced prior to backfilling.
4. Steel reinforcement will be required in the footings and foundation
wall. This will give the walls beam strength to span or bridge over
any loose or soft pockets of soil not found in our exploratory holes or
that may develop during construction. This should also help prevent
any differential movement of the foundation system. It is also
recommended to provide lateral support to walls by the use of
counterforts, as deemed necessary by foundation engineer.
5. The soils that will support the concrete slabs should be kept moist
during construction by occasional sprinkling of water and especially a
day or so prior to pouring of the slab. This procedure will help
maintain the moisture content of the underlying soil. **Heavy
watering or pooling of any kind next to the foundation or within the
backfilled area is not recommended.**
6. A minimum void or clear space of 11/2 inches should be provided at or
near the bottom of all non-bearing partitions. In finished room areas,
all drywall and paneling should be stopped approximately 1'h inches
above the top of the slab. This will allow some space for upward
movement of the slab before pressures are applied to the wall and
upper levels of the structure. The builder should provide a '/z inch
space at the bottom of all doorjambs to allow for limited movement of
the floor slab. The owner is hereby notified that it is their
responsibility to maintain these void spaces.
PRELIMINARY ENGINEERING ANALYSIS AND
RECOMMENDATIONS:
The preliminary recommendations presented in this report are based on the
assumption that the site has variable soil conditions within the proposed site.
As a result, we recommend that supplementary geotechnical engineering
exploration should be performed for each of the proposed structures on this
site. Supplemental geotechnical explorations will be used to confirm or
modify the recommendations made in this report.
CONSTRUCTION DETAILS:
In any soil investigation, it is necessary to assume that the subsurface soil
conditions do not vary greatly from the conditions encountered in the field
and laboratory testing. The accompanying design is presented using best
professional judgment based on the limits of the extent of testing
commissioned by the client. Our experience has been that at times, soil
conditions do change and variations do occur. These may become first
apparent at the time of excavation for the foundation system.
If soils conditions are encountered which appear different from the test
borings as presented in this report, it is recommended that this office be
called to inspect the open excavation prior to placing the footings. This
inspection is not part of the report.
The foundation and retaining walls should be well cured and well
braced prior to backfilling.
DISCLAIMER:
THE PARTIES SPECIFICALLY AGREE THAT HIGH PLAINS
ENGINEERING, INC. HAS NOT BEEN RETAINED NOR WILL THEY
RENDER AN OPINION CONCERNING ANY ENVIRONMENTAL
ISSUES, HAZARDOUS WASTE OR ANY OTHER KNOWN OR
UNKNOWN CONDITIONS THAT MAY BE PRESENT ON SITE.

suspension by flowing water and subsequently deposited by
sedimentation.
Aggregate Base Course A layer of specified materialplaced on a subgrade
y p or subbase
usually beneath slabs or pavements.
Bedrock A natural aggregate of mineral grains connected by strong and
permanent cohesive forces. Usually requires drilling,
wedging,blasting or other methods of extraordinary force for
excavation.
Bench A horizontal surface in a sloped deposit.
Caisson A concrete foundation element cast in a circular excavation
that may have an enlarged base. Sometimes referred to as a
cast-in-place pier or drilled shaft.
Coefficient of Friction A constant proportionality fader relating normal stress and the
corresponding shear stress at which sliding starts between the
two surfaces.
Colluvium Soil,the constituents of which have been deposited chiefly by
gravity such as the foot of a slope or cliff.
