Dear Mr. Radler:
Eagle County Building
P.O. Box 179
500 Broadway
Eagle, Colorado 81631-0179
As per your request, our office has resized your ISDS Permit #1860-99 from eight bedrooms to
five bedrooms. However, after checking your building plans on file in the Building Department
it was determined that the approved set of plans had indeed included an eight -bedroom residence,
with three of the bedrooms on the unfinished lower level. If at any time in the future you are
planning on finishing this area, you will need to expand the size of your septic system to include
these three bedrooms. Also, your Certificate of Occupancy will only include the two upper
levels of the home, and you will need to apply for another building permit to finish off the
basement area. .
You currently have a permit to install a septic system large enough to accommodate eight
bedrooms.' In order to reissue the ISDS Permit for five bedrooms, we will need a letter verifying
your intent to finish only the upper levels of the residence at this time, and acknowledgment of
the fact that you will have to reapply for a Building Permit and an ISDS Alteration Permit to
finish the lower level. A copy of the letter will be placed in both the Building Permit File and the
ISDS Permit File.
We realize that building costs are extremely high in this area, but they will only continue to
escalate in the future. We recommend that you install at least enough septic tank capacity for the
originally planned eight bedroom home, which would be 2250 gallons. That way you will only
have to add to the leach field and not worry about the tank size. This is only a recommendation.
Please call 328-8755 if you have any questions regarding any of the above.
Sincerely,
anet Kohl

Subject: Subsoil Study for Foundation Design, Proposed Residence, Lot 6A, Colorow at
Squaw Creek, Eagle County, Colorado.
Job No. 4 136 93
Dear Mr. Pritchard:
As requested, we have conducted a subsoil study at the subject site, located on Lot 6A, Colorow
at Squaw Creek in Eagle County, Colorado.
Subsurface conditions encountered in the exploratory borings drilled in the proposed building
area are variable and generally consist of clayey sand and gravel overlying sandstone and
siltstone bedrock. The clay fraction of the upper soil has a relatively high plasticity and may
have a low expansion potential when wetted. Groundwater was not encountered in the borings
at the time of drilling,
The proposed residence can be founded on spread footings placed on the natural subsoils or
bedrock and designed for an allowable bearing pressure of 2500 psf and a minimum dead load
- pressure of 600 psf. The foundation bearing soils should be evaluated at the time of excavation
to determine if expansive soils are present.
The report which follows describes our investigation, summarizes our findings, and presents our
recommendations. It is important that we provide consultation during design, and field services
during construction to review and monitor the implementation of the geotechnical recommenda-
tions.
IIf you have any questions regarding this report, please contact us.
Sincerely,
CHEN-NORTHERN, INC.

SURFACE DRAINAGE
The following drainage precautions should be observed during construction and
maintained at all times after the residence has been completed:
1) Excessive wetting or drying of the foundation excavations and underslab areas should be
avoided during construction. Drying could increase the expansion potential of clay soils.
2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least
95% of the maximum standard Proctor density in pavement 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 to 3 feet of the on -site 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 areas and a minimum slope of 3 inches in the first
10 feet in paved areas.
4) Roof downspouts and drains should discharge well beyond the limits of all backfill.
PERCOLATION TESTING
Percolation testing was performed at the locations shown on Fig. 1. Two profile holes
were drilled at the locations shown on Fig. 1 to determine a suitable area for percolation testing.
The logs of the profile holes are shown on Fig. 2. The subsurface conditions encountered in
Profile Hole 1 consist of about 1 foot of topsoil over about 1 foot of clayey gravel. Sandstone
bedrock was encountered at a depth of 2 feet to the full depth of exploration, 8 feet. Profile
Chen@Northern, Inc.
Consuuiny Engmeetsand Soenusis

Hole 2 was drilled southeast of the proposed building location. The subsoils encountered consist
Of 1 foot of topsoil overlying clayey gravel to a depth of 8 feet. No free water was encountered
in the profile holes. The shallow bedrock encountered in Profile Hole 1 indicates this area will
likely be unsuitable for a conventional infiltration septic stem.
P Y
Percolation testing was performed in three shallow 7-inch diameter borings near Profile
Hole 2. The results of the percolation testing are presented in Table II. The results indicate
infiltration into the u s bsoils is very slow and a conventional infiltration septic system may not
be feasible at this site. The slow percolation rates may be due to a combination of the soil type
and density and auger hole testing and, may not be representative of the true infiltration rate for
these soils. The auger drilling operation can cake or smear the sides of the boring which can
r
reduce the percolation rate. We recommend additional testing be performed in larger backhoe
dug holes to better determine infiltration rates. If the rates remain slow, an
evaporation/transpiration septic system may be a feasible alternative to a conventional infiltration
system. The selected system should be designed by a qualified engineer familiar with local
9 g
regulations pertaining to septic disposal systems.
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
borings drilled at the locations indicated on Fig. 1, the proposed type of construction and our
experience in the area. The nature and extent of subsurface variations across the site may not
Chen@Northern,'Inc.
Cunsuninr) Engineers and Scientists

become evident until 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
of excavations and foundation bearing strata and testing of structural fill by a representative of
the soil engineer.

•If field sample contained cobbles or boulders. or both.
add "with cobbles or boulders. or both" to group name.
`Gravels with 5 to 12% fines require duel symbols:
GW-GM well -graded gravel with silt
GW-GC well -graded gravel with clay
GP -GM poorly graded gravel with silt
GP -GC poorly graded gravel with clay
*Sands with 5 to 12% Fines require dual symbols:
SW-SM well -graded sand with silt
SW -SC well -graded sand with clay
SP-SM poorly graded sand with sill
SP-SC Itoorly graded sand with clay
