EXECUTIVE SUMMARY
The proposed residences should be supported with
conventional type spread footings,designed for an
allowable soil bearing pressure of 2000 psf.They should
construct the footings of the entire foundation on the
undisturbed,sandy gravel with large sandstone boulders.
See Foundation Recommendations.
SCOPE OF STUDY
This report presents the results of a subsurface Soil and Foundation Investigation for
proposed residences to be constructed on Lots 31 &32, Block 1,Vail Potato Patch,Town of
Vail,Eagle County,Colorado.The purpose of the subsurface soil and foundation investigation
was to determine the engineering characteristics of the foundation soil and to provide
recommendations for the foundation design,grading,and drainage.
Geologic hazard studies are outside of our scope of services.
SITE DESCRIPTION
Lot 31 is a 0.48-acres site and Lot 32 is a 0.73-acres site, located on the west side of
Potato Patch Drive, in the Town of Vail,Eagle County,Colorado.Lots 31 &32 had steep
topography.Vegetation on the lots consisted of sage brush,wild grass and some aspens.
Drainage is to the south and southwest. Lot 31 is vacant and Lot 32 has an existing residence.
LKP Engineering,Inc.

PROPOSED CONSTRUCTION
We have assumed that the proposed residences will consist of a two-story,wood frame
construction,with a walkout basement, on a concrete foundation. We understand that the current
residence located on Lot 32 will be razed. Loads are anticipated to be light,typical of residential
construction.
If the finalized plans differ significantly from the above understanding,they should
notify us to reevaluate the recommendations of this report.
FIELD INVESTIGATION
The field investigation conducted on May 17,2007, consisted of excavating, logging
and sampling two test pits.The test pits' locations are shown on Drawing No, 1. Excavation of
the test pits was done with a Cat 315C,trackhoe.We show the soil profiles of the test pits on the
Subsurface Exploration Logs, Figure No's one and two.Soil samples for laboratory soil analysis
and observation were taken at selected intervals.
SUBSURFACE SOIL AND GROUNDWATER CONDITION
The soil profiles encountered in the test pits were fairly uniform.Test Pit No. I had four
feet of topsoil over three feet of reddish brown,sandy gravel with large sandstone boulders.Test
Pit No.2 had five feet of topsoil over two feet of reddish brown,sandy gravel with large
sandstone boulders.Refusal was encountered at 7 feet in both test pits.Ground water was not
encountered in either test pit.

FOUNDATION RECOMMENDATIONS
The proposed residences should be supported with conventional type spread footings,
designed for a maximum allowable soil bearing pressure of 2000 psf.The footings, for the entire
foundation, should be placed on the undisturbed,sandy gravel with large sandstone boulders,
below all of the topsoil.
We recommend a minimum width of 16 inches for the continuous footings and 2 feet for
the isolated footing pads.Continuous foundation walls should be reinforced top and bottom to
span an unsupported length of at least 10 feet.
A minimum of 48 inches of backfill cover is recommended for frost protection of the
footing subsoils. The undersigned engineer should observe the foundation excavation to verify
that the soil conditions are uniform throughout the foundation excavation.
The foundation excavation should be free from excavation spoils,frost,organics and
standing water.The on-site soil free from topsoil,organics,and rock fragments smaller than six
inches, is suitable backfill material. Imported fill material,approved by the undersigned
engineer,might be necessary for the foundation backfill. Voids left in the excavation,due to
rock removal,should be filled with lean concrete. Footings should be constructed on a level
surface.
SLAB CONSTRUCTION
The natural on-site soils,exclusive of topsoil,organics,are suitable to support lightly
loaded slab-on-grade construction.The subgrade for the slab-on-grade construction should be
proof compacted to detect and remove soft spots.They should backfill overexcavated soft spots
and other underslab fill with the on-site soil,free from topsoil and organics, or other suitable
material, compacted to a minimum of 95 percent of the maximum standard Proctor density
(ASTM D-698).Suitable material should be free from topsoil,organics and rock fragments
greater than 3 inches.
The concrete slab should be constructed over a 4-inch layer of clean gravel consisting of
-3/4 inch gravel with at least 50%retained on the No.4 sieve and less than 3 percent passing the
LKP Engineering,Inc.
5
No.200 sieve.
They should reinforce the concrete slab-on-grade and score control joints according to
the American Concrete Institute requirements and per the recommendations of the designer to
reduce damage due to shrinkage.The concrete slab should be separated from the foundation
walls and columns with expansion joints to allow for independent movement without causing
damage.
RETAINING WALLS
They should design foundation walls retaining earth and retaining structures that are
laterally supported to resist an equivalent fluid density of 60 pcf for an"at-rest"condition.
Laterally unrestrained structures retaining the on-site earth should be designed to resist an
equivalent fluid density of 40 pcf for the"active"case.
The above design recommendations assume drained backfill conditions and a horizontal
backfill surface. Surcharge loading due to adjacent structures,weight of temporary stored
construction materials and equipment, inclined backfill and hydrostatic pressure due to
undrained backfill should be incorporated in the design.They should try to prevent the buildup
of hydrostatic pressure behind the retaining wall.
UNDERDRAIN SYSTEM
To reduce the risk of surface water infiltrating the foundation subsoil,installation of a
foundation perimeter drain(see Figure No.3)is recommended.The foundation perimeter drain
should consist of a 4-inch diameter perforated pipe sloped to a suitable gravity outlet,or to a
sump pump location.The drain should slope at 1/4 inch per foot if flexible or at 1/8 of an inch if
rigid pipe is used.The bottom of the trench adjacent to the footing should be lined with a
polyethylene moisture barrier glued to the foundation wall. The drain pipe should be placed over
the moisture barrier and covered with a minimum of 6 inches of-3/4 inch free-draining granular
material.Geotextile(Mirafi 140N or equivalent)should be used to cover the free-draining gravel
to prevent siltation and clogging of the drain.The backfill above the drain should be granular
LKP Engineering, Inc.

material to within 2 feet of the ground surface to prevent a buildup of hydrostatic pressure.The
top one foot of the backfill material should consist of a relatively impervious fill.The backfill
should slope away from the building.
SITE GRADING AND DRAINAGE
A site plan was not available for review at this time. The following recommendations
are general in nature.The site surrounding the building structure should slope away from the
building in all directions.A minimum of 12 inches in the first 10 feet is recommended in
unpaved areas,and three inches in the first 10 feet in paved areas.The top of the granular
foundation backfill should be covered with a minimum of 1 foot of relatively impervious fill to
reduce the potential of surface water infiltrating the foundation subsoils.
Surface water naturally draining toward the proposed building site or permanent cuts,
should be diverted around and away from it by means of drainage swales or other approved
methods.The roof drains and downspouts should extend and discharge beyond the limits of the
backfill. Exterior backfill should be compacted at or near the optimum moisture content to at
least 95%of the maximum standard Proctor density under pavement,sidewalk and patio areas
and to at least 90%of the maximum standard Proctor density under landscaped areas.
Mechanical methods of compaction should be used.Do not puddle the foundation excavation.
LAWN IRRIGATION
It is not recommended to introduce excess water to the foundation soils by installing
sprinkler systems next to the building.The installation of the sprinkler heads should insure that
the spray from the heads will not fall within 10 feet of foundation walls,porches or patio slabs.
Lawn irrigation must be controlled.

The findings and recommendations of this report are based on field exploration,
laboratory testing of samples obtained at the specific locations shown on the Location Sketch,
Drawing No.I and on assumptions stated in the report.Soil conditions at other locations may
