Glenwood Springs, Colorado 816()f Job No. 102 527
Subject: Subsoil Study for Foundation Design and Percolation Test, Proposed
Residence, Lot 35, Westbank Mesa, Garfield County. Colorado
Dear Mr. Villemaire:
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study and
percolation test for foundation and septic disposal designs at the subject site. The study
was conducted in accordance with our agreement for geotechnical engineering services
to you dated July 31, 2002. The data obtained and our recommendations based on the
proposed construction and subsurface conditions encountered are presented in this
report Evaluation 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 above a walkout basement located on the site as shown on Fig. 1. Ground
floors are proposed to be slab-on-grade. Cut depths are expected to range between
about 4 to 8 feet. Foundation loadings for this type of construction are assumed to be
relatively light and typical of the proposed type of construction. The septic disposal
system is proposed to be located downhill and northwest of the residence.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to re-evaluate the recommendations presented in
this report.
Site Conditions: Lot 35 is located on the uphill side of Huebinger Drive. The ground
surface in the building area is hilly and moderately steep with 25% slopes down to the
north-northeast. The lot is vegetated with scattered juniper and pinon trees, sagebrush,
grass and weeds.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating two exploratory pits in the building area and one profile pit in the septic
disposal area at the approximate locations shown on Fig. 1. The logs of the pits are
presented on Fig. 2. The subsoils encountered, below about 1 foot of topsoil, consist of
Villemaire Construction
August 14, 2002
Page2
sandy silty clay with scattered rock fragments. Results of swell-consolidation testing
performed on relatively undisturbed samples of the clay, presented on Figs. 3 and 4,
indicate low compressi'bility under existing low moisture conditions and light loading
and moderate to high compressibility under additional loading after wetting. The
sample showed a low collapse potential (settlement under constant load) when wetted.
No free water was observed in the pits at the time of excavation and the soils were
slightly 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 natural soil de.~gned for an allowable soil bearing
pressure of 1,200 psf for support of the proposed residence. The soils tend to compress
after wetting and there could be some post-constructjon foundation settlement on the
order of 1 to 2 inches or more depending on the depth and extent of wetting. Footings
should be a minimum width of 20 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 to expose the undisturbed natural soils. The exposed
subgrade should then be moistened and compacted. 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 reinforced top and bottom to span local
anomalies such as by assuming an unsupported length of at least 14 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 soil as backfill.
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, 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.
H-P GEOTECH
"" . '
Villemaire Construction

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.
Underdraln System: Although free water was not encountered during our exploration,
it has been our experience in the area that local perched groundwater can 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, crawlspace 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 1 ~feet deep. An impervious
membrane such as 20 mil PVC could be placed beneath the drain gravel in a trough
shape and attached to the· foundation wall with mastic to help prevent wetting of the
bearing soils.
Surface Drainage: The following drainage precautions should be observed during
construction and maintained at all times after the residence has been completed:
1) Inundation of the foundation excavations and underslab areas should be
avoided during construction.
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 about 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
H-P GEOTECH
Villemaire Construction
August 14, 2002
Page4
areas and a minimum slope of 3 inches in the first 10 feet in pavement
and walkway areas. A swale may be needed uphill to direct surface
runoff around the residence.
4) Roof downspouts and drains should discharge well beyond the limits of
all backfill.
5) Landscaping which requires regular heavy irrigation should be located at
least 10 feet from the building. Consideration should be given to the use
of xeriscape to limit potential wetting due to irrigation.
Percolation Testing: Percolation tests were conducted on August 8, 2002 to evaluate
the feasibility of an infiltration septic disposal system at the site. One profile pit and
three percolation holes were dug at the locations shown on Fig. 1. The test holes
(nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow
backhoe pits and were soaked with water one day prior to testing. The soils exposed in
the percolation holes are similar to those exposed in the Profile Pit shown on Fig. 2 and
consist of sand silty clay. Scattered basalt cobbles and boulders were encountered in the
lower 3 feet of the pit. The percolation test results are presented in Table II. Based on
the subsurface conditions encountered and the percolation test results, the tested area
should be suitable for a conventional infiltration septic disposal system ..
Limitations: This study has been conducted in accordance with generally accepted
geotechnical engineering principles and practices in this area at this time. We make no
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, 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
H-PGEOTECH

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 let us know.

Re: Westbank, Lot 35 ISDS Inspection
Mr. Villemaire:
The following letter is provided per our inspection of the installation of the septic
system components for the residence on Lot 35 of the Westbank Ranch P.U.D.
outside of Glenwood Springs, Colorado.
The septic system was sized by our office for a minimum septic tank capacity of
1, 125 gallons, and a minimum of 45 infiltrator units arraigned in a trench layout.
The actual septic tank had a capacity of 1,500 gallons, and there were a total of 45
infiltrator units installed in five parallel trenches of nine infiltrator units in length
each.
The final inspection for the system was on December 19th and 23'd of 2002. Per
our inspections and information the system was constructed in accordance with
the intended layout and design.
If you have any questions, please call.
