Dear Mr. Dunsdon:
At your request on May 5,1996, we visited the construction site at Lot 6, Section 15, T2S, R83 W of
the 6th P.M. in Burns, Colorado. The purpose of our site visit was to inspect the installation of the Septic
System for the new church.
The system was installed in general compliance with the design reeonunmdations shown on the
Septic System Desiga Plan, dated July 6, 1995. Fifteen hundred -gallon two compartments, precast concrete
tams by Copland Concrete, was installed seven feet southwest from the southwest corner of the ,new church.
Two trenches with 9 Standard Infiltrator Chambers in each, were installed west of the septic tank. The
infiltrators in the two trenches were connected by serial distribution at the west end. Cleanout parts were
installed in the last Infiltrator unit of each trench. Tlae upper trench was about 1.5 feet drop and the lower
was about 2.5 feet deep. The soil exposed in the trenches consisted oaf brown sandy topsoil, as anticipated
from the test pit.

Dear Applicant,
Eagle County Building
P.O. Box 179
500 Broadway
Eagle, Colorado 81631-0179
The Environmental Health Division would like to notify you to
make a formal request to extend your Individual Sewage Disposal
System(ISDS) Permit into the 1996 construction year. The
Environmental Health Division discontinued percolation tests on
November 15, 1995 and.final inspections on December 2, 1995 due
to climatic conditions.
ISDS permits are active for 120 days after the date of issue if
no Building Permit has been issued for the same property. If a
Building Permit has been issued for the same property the ISDS
will expire at the same time as the building permit.
If you still plan to apply for a Building Permit this year or in
the early months of 1996 you will need to have a percolation test
conducted before your Building Permit will be released. You will
have to contact a Registered Professional Engineering(RPE) firm
to conduct your percolation test.
If you have had your permit issued and have not had your final
inspection completed, but plan on constructing the system in the
next few weeks, please give our office a call and we will
evaluate your permit on a case by case situation.
Please give the Environmental Health office a call at 328-8755,
if you have any questions regarding your permit extension
process.

EXECUTIVE SUMMARY
The proposed church should be supported with
conventional type spread footings, designed for
an allowable soil bearing pressure of 1,500 psf.
The footings should be placed on the undisturbed
fine SAND.
SCOPE OF STUDY
This report presents the results of a subsurface Soils and Foundation Investigation for a
proposed church to be constructed on Lot 6, Section 15, T2S, R85W of the 6th Principal Meridian,
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.
SITE DESCRIPTION
The lot is located in Section 15, T2S, R85W of the 6th Principal Meridian, Eagle County,
Colorado. The site is approximately 11 miles west of U.S. Highway 131, on the road to Burns. On the
north side of the lot is the County Road. To the west and southwest is Colorado River. To the south
is the Denver and Rio Grande Railroad. To the east are the Cabin Creek and a private property.
The topography of the site is relatively flat to moderate, sloping gently to the south and
southwest, toward Colorado River and Cabin Creek. There are two existing buildings on the lot, as
shown on the Location Sketch. One of the buildings is an old school building, and the other one is
old garage.
2
The vegetation consisted of grass, some pine trees, and shrubs. Drainage is to the south and
southwest.
PROPOSED CONSTRUCTION
Based upon information provided by Mr. Bruce Dunsdon, it is understood that the proposed
church will consist of a single level wood frame construction with a walkout basement. Loads are
anticipated to be light.
If the finalized plans differ significantly from the above understanding, we should be notified
to reevaluate the recommendations of this report.
FIELD INVESTIGATION
The field investigation conducted on June 27, 1995, consisted of excavating logging and
sampling two test pit. The test pit locations are shown on Figure No. 1. The excavation of the test pits
was done with a conventional backhoe. The soil profiles of the test pits are shown on the Subsurface
Exploration Logs, Figure No's 1 and 2. Soil samples for laboratory soil analysis and observation
were taken at selected intervals.
SUBSURFACE SOIL AND GROUNDWATER CONDITION
As shown on the Subsurface Exploration Logs, Figure No's 1 and 2, the subsurface soil
conditions consisted of abo eet of Topsoil with fine roots, over 5 feet of slightly silty SAND, in
Test Pit No. 1, andf-feet of topsoil and man made fill over 4 feet of fine SAND in Test Pit No. 2.
Ground water was encountered in the Test Pit No. 1 ao' t. There was no groundwater
encountered in Test Pit No. 2.
The soil samples taken from the test pit were tested for swell/consolidation, moisture
content, unit weight, and grain size distribution. The test results are shown on Figure No's 3 and 4.
The laboratory test results showed low potential for hydro consolidation (additional settlement upon
addition of water).
3
FOUNDATION RECOMMENDATIONS
The proposed church should be supported with spread footings, designed for a maximum
allowable soil bearing pressure of 1500 psf. The footings should be placed on undisturbed sand.
Minimum width of 16 inches is recommended 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 foundation excavation should be observed by the undersigned to verify that the soil
conditions encountered during construction are as anticipated in this report.
The foundation excavation should be free from excavation spoils, frost, organics and
standing water. Any overexcavation within the proposed foundation, should be backfilled, in 8 inches
loose level lifts and compacted to 100% of the maximum dry density and within 2 percent of the
optimum moisture content as determined in a laboratory from a Standard Proctor test (ASTM D-
698). Structural fill placed under footings should be tested by the engineer or her representatives on
regular basis.
SLAB CONSTRUCTION
The natural on -site soils, exclusive of topsoil and 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. Overexcavated soft spots and other underslab fill should
be backfilled with the on -site soil 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
M
inch gravel with at least 50% retained on the No. 4 sieve and less than 3 percent passing the No. 200
sieve.
The concrete slab -on -grade should be reinforced and control joints scored in accordance with
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
Foundation walls retaining earth and retaining structures which are laterally supported should
be designed to resist an equivalent fluid density of 50 pcf for an "at -rest" condition. Laterally
unrestrained structures retaining the on -site earth should be designed to resist an equivalent fluid
density of 30 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. Every attempt should be made to prevent the buildup
of hydrostatic pressure behind the retaining wall.
UNDERDRAIN SYSTEM
In order to reduce the risk of surface water infiltrating the foundation subsoil, installation of a
foundation perimeter drain 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, at a
1/4 inch per foot if flexible or at a 1/8 of an inch if rigid pipe. 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
5
cover the free -draining gravel to prevent siltation and clogging of the drain. The backfill above the
drain should be granular material to within 2 feet of the ground surface to prevent a buildup of
hydrostatic pressure.
SITE GRADING AND DRAINAGE
A site plan was not available for review at this time.
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.
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 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.
LAWN IRRIGATION
It is not recommended to introduce excess water to the foundation soils by installing
sprinkler systems adjacent to the building. The installation of the sprinkler heads should insure that
the spray from the heads will not fall within 5 feet of foundation walls, porches or patio slabs. Lawn
irrigation must be controlled.

LIMITATION
This report has been prepared in accordance with locally accepted professional Geotechnical
engineering standards for similar methods of testing and soil conditions at this time. There is no
other warranty either expressed or implied.
The findings and recommendations of this report are based on field exploration, laboratory
testing of samples obtained at the specific locations shown on the Site Plan Figure No. 1 and on
assumptions stated in the report. Soil conditions at other locations may vary, which may not become
evident until the foundation excavation is completed. If soil or water conditions appear to be
different from those described in this report we should be contacted immediately to reevaluate the
recommendations of this report.
This report has been prepared for the exclusive use of Mr. Bruce Dunsdon for the specific
application to the proposed church to be located on Lot 6, Section 15, T2S, R85W of the 6th P.M.,
Eagle County, Colorado.
