Subject: Subsoil Study -for Foundation Design and Percolation Test, Proposed
Residence, Lot 24, Sopris Mesa Subdivision, Green Mountain Drive, F f
Eagle County, Colorado. v
Dear Mr. Schrock:
As requested, Hepworth-Pawlak Geoteehnical, 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 March 14, 2002TIm data obtained and our recommendations based on
the proposed construction and subsurface conditions encountered are presented in this
report. Hepworth Pawlak Geotechnical, Inc., previously conducted a preliminary
eotechnical study y for the Sopris Mesa Subdivision and presented our findings in a
report dated October 23, 1997, Job No. 197 495.
Proposed Construction: At the time of our .study, design plans for the residence had
not been developed. We understand that the results of this study will be considered in
the purchase of the property. We assume the residence win be typical of the area and
consist of a one to two story wood frame structure over a walkout basement level or
crawlspace. We assume excavation for the building will have a maximum cut depth of
one level, about 8 to 10 feet below the existing ground surface.. For the purpose of our
analysis, foundation loadings for the structure were assumed to be relatively light and
typical of -the assumed type of construction. We assume the septic disposal system will
be located downhill to the southeast of the proposed residence.
If building loadings, location or grading plans are significantly different from those
described above, we should be notified to re-evaluate the recommendations contained in
this report.
Site Conditions: The site was vacant and covered with patchy snow at the time of our
field exploration. The ground surface is rolling terrain with a moderate slope down to
the southeast. An existing irrigation .ditch is located uphill to the north of the building
envelope. The lot is vegetated with scattered sagebrush, grass and weeds. Scattered
basalt cobbles are exposed on the ground surface.
Jim Schrock
March 26, 2002
Page 2
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 Iogs of the pits are
presented on Fig. 2. The subsoils encountered, below about '/h to 1 foot of topsoil and
I to 21/z feet of very stiff sandy clay, consist of basalt cobbles and boulders in a gravelly
silt and sand matrix. Pugging in the basalt cobbles and boulders was difficult and
refusal to digging was encountered in the pits. Results of swell -consolidation testing
performed on relatively undisturbed samples of upper clay soils, presented on Fig. 3,
indicate low compressibility under existing moisture conditions and light loading and a
low expansion potential when -wetted. 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 _na-him of the proposed construction, -we recommend spread
footings placed on the undisturbed- natural basalt rock soil designed for an allowable soil
bearing pressure of 3,000 psf for support of the proposed residence. The upper clay
soils are expansive when wetted and should be removed beneath the building area.
Footings should be a minimum- width of 16 inches for continuous walls and 2 feet for
columns.. The upper clay- soils and .loose disturbed -sails -encountered -at the foundation
bearing- level within the excavation should be removed and the footing bearing level
extended down to the undisturbed natural basalt rock. As an alternative, design bearing
levels can be -re-established with compacted structural fill- The fill should consist of
imported granular material compacted to at least 1009a' of standard Proctor density at a
moisture- content near optimum. The fill should extend laterally out from the footing a
distance at least equal to the depth of fill beneath the footing. Boulders in the subsoils
will make excavation difficult_ Voids created by the removal oflarge rocks should be
backfilled with compacted granular material, such as road base, or with -concrete.
Exterior footings should beprovided 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 1,0
feet. Foundation walls acting as reWbinxg structures should be designed -to resist a
lateral earth pressure based on an equivalent fluid unit weight of at least 45 pcf for the
on -site soils,. excluding vegetation, topsoil, clay soils or oversized rock, as backfill.
Floor Slabs: The natural on -site soils, exclusive of topsoil and expansive clay soils, are
suitable- to support lightly loaded slab--on-grade construction. The upper expansive clay
soils- should be removed beneath. the building floor slab areas. To reduce the effects of
Jim Schrock
March 26, 2002
Page 3
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.
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 rocky soils or imported granular -material devoid of -vegetation,
topsoil and oversized rock.
Underdrain 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 h feet -deep.
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 sods to reduce
Jim Schrock
March 26, 2002
Page 4
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.
4) Roof downspouts and drains should discharge well beyond the limits of
all backfill.
percolation Testing. Percolation tests were conducted on March 19, 2002 to evaluate
the feasibility of an infUtration septic disposal system at the site. One profile pit and
three. percolation holes were dug at the locations shown -on Big. 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- tar testing. The soils exposed in
the percolation holes are similar to those exposed in the Profile Fit shown on Fig. 2 and
consist of about lh foot of topsoil and 21h feet of stiff sandy clay overlying basalt
gravel, cobbles and boulders in a silt and sand matrix to the pit depth of 71/2 feet. The
percolation test results are, presented in Table IL The percolation test results indicate a
percolation rate between 30 and 60 mimites per inch with -arr average of 40 minutes per
inch for the underlying, granular soils. Based on- the subsurface conditions encountered
and the percolation test results, the tested area should be- suitable for a conventional
infiltration septic disposaL system. The -system should extend completely through the
upper clay soils and into the underlying basalt rock subsoils.
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 frorn 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 andextrapolation 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
theproject 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 fillby a representative of the geotechnical
engineer.
If you have any questions or if we may be of further assistance, please let us know.
