Dear Hank,
------·----·------------------·-···--
Based on the preliminary plans which you submitted last fall for the design of your house on Lot 1 of
the Pinyon Peaks Subdivision, the Architectural Control Committee has granted conditional approval.
This approval is contingent upon the Committee receiving the final plans and evidence that no major
modifications have taken place. If the final plans are submitted to the Committee and have in fact not
changed significantly from those preliminary plans previously submitted, final approval will be granted.
Unrelated to the actual house construction, we still will need to review the location of the septic/leach
field as well as your resolution for electric service. As these are not significant issues and do not effect
the location of the house, we are willing to review them at a convenient time. As with the final plans,
these will need to be reviewed prior to the final approval.
We appreciate the fact that you incorporated the concerns we voiced at our on-site meeting and
incorporated them into the plans that you submitted. I believe that this house will "fit" the site well and
in so doing preserve the natural integrity of the site. I look forward to seeing this house built as it will
be an asset to our subdivision.
If you have any questions or comments please do not hesitate to contact me.
Sincerely,
~atM?~
Thomas G. Stevens

Subject: Subsoil Study for Foundation Design, Proposed Residence, Lot 1, Pinyon Peaks
Subdivision, Garfield County, Colorado.
Job No. 4 190 93
Dear Mr. Gray:
As requested, Chen-Northern, 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 Hank Gray, dated December 4, 1992. The data obtained and our
recommendations based on the proposed construction and subsurface conditions encountered are
presented in this report.
Proposed Construction: The proposed residence will be a two-story wood frame structure with
a garden level basement located approximately as shown on Fig. 1. Cut depths will be relatively
minor and probably up to about 6 feet below the existing ground surface. 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 proposed development site consists of vacant property along the uphill side
of County Road 112. The ground surface slope across the lot is variable and generally moderate
to steep. Elevation difference within the building area is about 6 feet. Shallow snow depth and
numerous cobbles and boulders covered the ground surface. The area is heavily wooded with
pinon and juniper trees and an understory of grass, weeds and sagebrush.
Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two
exploratory pits at the approximate locations shown on Fig. 1. The building site was identified
by Dave Doolen, contractor. The pits were excavated with a rubber-tired backhoe. The logs
of the pits are presented on Fig. 2. The subsoils encountered, below about 1 foot of cobbley
topsoil, consist mainly of silty sandy clay with varying amounts of basalt rock fragments. The
soils are slightly to heavily calcareous and slightly to moderately porous. Results of swell-
consolidation tests performed on relatively undisturbed samples of the clay soils, shown on
Fig. 3, indicate low compressibility under relatively light surcharge and moderate to high
compressibility potential when wetted and loaded. Results of gradation analyses and Atterberg

limits testing, presented in Table I, indicate the soils are mainly low plasticity silty clay. No
free water was observed in the pits at the time of excavation and the soils were relatively dry.
Foundation Recommendations: Considering the subsoils encountered in the exploratory pits and
the nature of the proposed construction, we recommend spread footings placed on the
undisturbed natural soil designed for. an allowable soil bearing pressure of 1500 psf for support
of the proposed residence. The soils become compressible when wetted which could result in
some post-construction foundation settlement. Precautions to help prevent wetting of the bearing
soils such as by providing positive surface drainage away from the structure, using PVC liner
material below the underdrain system and pressure testing utility lines should be observed.
Footings should be a minimum width of 16 inches for continuous walls and 2 feet for columns.
Loose and disturbed soils and any existing fill encountered at the foundation bearing level within
the excavation should be removed and the footings extended down to the natural soils. The
excavation should be protected against frost during construction. Exterior footings should be
provided with adequate cover above their bearing elevations for frost protection. Placement of
footings at least 36 inches below the exterior grade is typically used in this area. Continuous
foundation walls should be well 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 50 pcf for backfill consisting of the on-site soils devoid of vegetation, topsoil and
oversized rock.
Floor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded
slab-on-grade construction. To reduce the effects of some differential movement which may
occur, floor slabs should be separated from all bearing walls and columns with expansion joints
which allow unrestrained vertical movement. 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 should be placed beneath basement level 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.
Underdrain System: Although free water was not encountered during our exploration, it has
been our experience in mountainous areas that local perched groundwater may develop during
times of heavy precipitation or seasonal runoff. Frozen ground during spring runoff can also
create a perched condition. We recommend below grade construction, such as retaining walls,
crawl space and basement 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 2 feet deep.
An impervious membrane, such as 20 mil PVC, should be placed below the drain gravel in a
trough shape and attached to the foundation wall with mastic to prevent wetting of the bearing
soils.
Surface Drainag.e: The bearing soils may tend to settle when wetted and precautions should be
taken to prevent moisture infiltration to below the building. The following drainage precautions
should be observed during construction and maintained at all times after the residence has been
completed:
1)
2)
3)
Inundation of the foundation excavations and underslab areas should be avoided during
construction.
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.
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)
5)
Roof downspouts and drains should disclJarge well beyond the limits of all backfill.
Utility lines should be pressure tested for leaks and repaired as necessary prior to
backfilling.
6) Landscape irrigation should be limited within about 10 feet of the building.
Limitations: This report has been prepared in accordance with generally accepted soil and
foundation engineering practices in this area for use by the client for design purposes. 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 the proposed type of
construction. The nature and extent of subsurface variations across the site may not become
evident until further excavation is performed. If during construction, fill, soil, rock or water
conditions appear to be different from those described herein, this office should be advised at
once so reevaluation of the recommendations may be made. We recommend on-site observation
