Subject: Subsoil Study for Foundation Design, Proposed Residence, Lot 16,
Horse Mountain Ranch, Eagle County, Colorado.
Dear Mr. Howard:
As requested, Hepworth-Paw1_ak Geotechnical, Inc. performed a subsoil study for
design of foundations at the subject site. The study was conducted in accordance with
our agreement for geotechnical engineering services to you dated October 18, 1996.
The data obtained and our recommendations based on the proposed construction and
subsurface conditions encountered are presented in this report. Assessment of potential
geologic hazard impacts on the site are beyond the scope of this study.
Proposed Construction: The proposed residence will be a one story wood frame
structure with an attached garage located on the site as shown on Fig. 1. An apartment
will be built above the garage. Ground floors will be structural over a crawlspace for
the residence and slab -on -grade in the garage. Cut depths are expected to range up to
about 8 feet. Foundation loadings for this type of construction are assumed to be
relatively light.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to reevaluate the recommendations presented in
this report.
Site Conditions: The site was vacant and covered with between about '/2 and 1 foot of
snow at the time of our field work. Topography in the area is gently rolling with a
ground surface slope of about 12 % down to the east in the building area. Elevation
difference is about 10 feet across the proposed building area. A dry shallow drainage
runs through the northern side of the proposed building. A spring is located about 60
feet downhill to the east of the building location. Vegetation consists of sagebrush,
grasses and weeds. Scattered boulders comprised of vesicular basalt are present on the
ground surface.
Tom Howard
November 11, 1996
Page 2
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating three exploratory pits at the approximate locations shown on Fig. 1. The
logs of the pits are presented on Fig. 2. The subsoils encountered, below about 1 _foots
of topsoil, consist of relatively dense clayey sand and gravel with cobbles and boulders.
About 5 feeDf slightly organic cla e� y silt was found above the gravel in Pit 1
excavated in the shallow drainage. Results of swell -consolidation testing performed on
relatively undisturbed samples of the sandy clay matrix, presented on Fig. 3, indicate
low compressibility under existing moisture conditions and light loading and a low
expansion potential when wetted. Results of gradation analyses performed on samples
of the clayey gravel (minus 3 inch fraction) obtained from the site are presented on
Fig. 4. No free water was observed in the pits at the time of excavation and the soils
were slightly moist to moist.
Foundation Recommendations: Considering the subsoil conditions encountered in the
exploratory pits and the nature of the proposed construction, we recommend spread
footings placed on the undisturbed gravel soil designed for an allowable soil bearing
pressure of 3,000 psf for support of the proposed residence. The silt soils encountered
at Pit 1 should be removed from the building area. Due to the expansive clay matrix
soils, the footings should be designed to impose a minimum dead load pressure of 800
psf. The subgrade should be evaluated for expansive soils at the time of excavation.
Settlement/heave of footings should be on the order of 1 inch or less depending on the
depth and extent of any wetting below the foundation. Footings should be a minimum
width of 16 inches for continuous walls and 2 feet for columns. Loose and disturbed
soils encountered at the foundation bearing level within the excavation should be
removed and the footing bearing level extended down to the undisturbed gravel
subsoils. Voids created by boulder removal should be backfilled with compacted gravel
or with concrete. Exterior footings should be provided with adequate cover above their
bearing elevations for frost protection. Placement of footings at least 42 inches below
the exterior grade is typically used in this area. Continuous foundation walls should be
reinforced top and bottom to span local anomalies such as by assuming an unsupported
length of at least 12 feet. Foundation walls acting as retaining structures should be
designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at
least 50 pcf for the on -site gravelly soil as backfill, exclusive of oversized rock.

Tom Howard
November 11, 1996
Page 3
Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support
lightly loaded slab -on -grade construction. The clay matrix of these soils possess an
expansion potential and slab heave could occur if the subgrade soils were to become
wet. To reduce the effects of some differential movement, floor slabs should be
separated from all bearing walls and columns with expansion joints which allow
unrestrained vertical movement. Slab bearing partition walls should be provided with a
slip joint at the bottom of the wall to allow for slab heave up to about 11/2 inches. Floor
slab control joints should be used to reduce damage due to shrinkage cracking. The
requirements for joint spacing and slab reinforcement should be established by the
designer based on experience and the intended slab use. A minimum 4 inch layer of
free -draining gravel can be placed beneath interior floor slabs to facilitate drainage.
This material should consist of minus 2 inch aggregate with less than 50% passing the
No. 4 sieve and less than 2% passing the No. 200 sieve.
All fill materials for support of floor slabs should be compacted to at least 95 % of
maximum standard Proctor density at a moisture content near optimum. Required fill
can consist of the on -site soils devoid of vegetation, topsoil and oversized rock or
imported sand and gravel, such as road base aggregate.
Underdrain System: Although free water was not encountered during our exploration,
it has been our experience in mountainous areas and where clay soils are present that
local perched groundwater may develop during times of heavy precipitation or seasonal
runoff. Frozen ground during spring runoff can create a perched condition. We
recommend below -grade construction, such as retaining walls and crawispace areas, be
protected from wetting and hydrostatic pressure buildup by an underdrain system.
The drains should consist of drainpipe placed in the bottom of the wall backfill
surrounded above the invert level with free -draining granular material. The drain
should be placed at each level of excavation and at least 1 foot below lowest adjacent
finish grade and sloped at a minimum 1 % to a suitable gravity outlet. Free -draining
granular material used in the underdrain system should contain less than 2 % passing the
No. 200 sieve, less than 50% passing the No. 4 sieve and have a maximum size of
2 inches. The drain gravel backfill should be at least 11/2 feet deep.
H-P GEOTECH
Tom Howard
November 11, 1996

Surface Drainage: The following drainage precautions should be observed during
construction and maintained at all times after the residence has been completed:
1) Excessive wetting or drying of the foundation excavations and underslab
areas should be avoided during construction. Drying could increase the
expansion potential of the clay soils.
2) Exterior backfill should be adjusted to near optimum moisture and
compacted to at least 95 % of the maximum standard Proctor density in
pavement and slab areas and to at least 90 % of the maximum standard
Proctor density in landscape areas. Free -draining wall backfill should be
capped with at least 2 feet of the on -site, finer graded soils to reduce
surface water infiltration.
3) The ground surface surrounding the exterior of the building should be
sloped to drain away from the foundation in all directions. We
recommend a minimum slope of 12 inches in `the first 10 feet in unpaved
areas and a minimum slope of 3 inches in the first 10 feet in pavement
and walkway areas. A Swale will be needed uphill to direct surface
runoff around the residence.
4) Roof downspouts and drains should discharge well beyond the limits of
all backfill
Limitations: This report has been prepared in accordance with generally accepted
geotechnical engineering principles and practices in this area at this time. We make no
other warranty either expressed or implied. The conclusions and recommendations
submitted in this report are based upon the data obtained from the exploratory pits
excavated at the locations indicated on Fig. 1 and to the limited depths shown on Fig.
2, the proposed type of construction, and our experience in the area. Our findings
include interpolation and extrapolation of the subsurface conditions identified at the
exploratory pits and variations in the subsurface conditions may not become evident
until excavation is performed. If conditions encountered during construction appear
different from those described in this report, we should be notified at once so re-
evaluation of the recommendations may be made.

This report has been prepared for the exclusive use by our client for design purposes.
We are not responsible for technical interpretations by others of our information. As
the project evolves, we should provide continued consultation and field services during
construction to review and monitor the implementation of our recommendations, and to
verify that the recommendations have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein. We recommend on -site observation of excavations and foundation
bearing strata and testing of structural fill by a representative of the geotechnical
engineer.
If you have any questions or if we may be of further assistance, please call our office.
