RE: Cordillera Septic Systems
Dear Terrill:
This letter is intended to summarize the geologic conditions
for purposes of waste disposal in the central part of the
Cordillera Subdivision where most of the multi -family systems
will be.
As indicated in my earlier report and the Lincoln/DeVore
report, the sandstones, siltstones and shales of the
formations in that area are very steeply to vertically
dipping and highly weathered. In the many test holes that we
excavated in this vicinity, the permeable soils graded into
similarly permeable weathered bedrock which graded into
fractured bedrock. It was considered that the permeable
"soil" profile existed to at least the top of the fractured
bedrock, which in most cases yielded at least eight feet of
suitable material. There were, however, certain areas where
fractured bedrock was nearer the surface than this, and that
is why more detailed site investigations were performed.
Percolation rates were nearly always in the acceptable range
and at least several suitable sites were found in all areas.
I anticipate no problem in lbcating adequate drain field
sites as long as fractured bedrock is greater than eight feet
below the surface. It should be remembered that resistant
sandstone beds run through the development very near or at
the surface, and these must be avoided.
I hope I have answered your questions, but feel free to
contact me again.

REVISED APRIL 1988
Box No. 978 1420 Vance Street

SCOPE
This report presents the results of percolation tests
and provides septic system recommendations for the proposed
single family residence on Lot 48, Cordillera Subdivision,
Filing No. 2, Eagle County, Colorado.
SITE INVESTIGATION
The site was investigated on October 20, 1987, and three
percolation test holes were dug to a minimum depth of
30 inches. Holes were presoaked and percolation tests per-
formed on October 26, 1987. Results of these tests are
included in this report; see PERCOLATION TEST RESULTS. A
test pit was excavated to a depth of 7 feet on October 27, 1987
with a conventional backhoe. The locations of the percolation
test holes are shown on Drawing No. 1. A summary of the test
pits is detailed on Figure No. 1.
SITE LOCATION AND DESCRIPTION
The site is located at G095 Grand Traverse in Eagle County,
Colorado. A ridge line running north to south divides the
lot. Drainage in the area of the absorption trenches is to
the west. Vegetation consists of sage brush and grasses.
E
SUBSURFACE AND GROUNDWATER CONDITIONS
. Subsurface conditions in the proposed leach field area
are uniform, and consist of topsoil to a depth of 1-1/2 feet
underlain by very weathered bedrock to a depth of 7 feet
underlain by bedrock.
Nicholas Lampiris, Ph.D., has studied the subdivision
to determine the suitability of the area for individual septic
systems. The enclosed letter dated October 30, 1987, states
that the permeability of the weathered bedrock is similar to
soil.
PERCOLATION TEST RESULTS
A total of three percolation tests were performed on
the site as specified by the Eagle County Individual Sewage
Disposal System Regulations. Results were as follows:
Test Hole Min/1" Drop Date of Test Ambient Air Temp.
1 7.1 10/21/87 500 F
2 10.9 10/21/87 500 F
3 10.0 10/21/87 500 F
Average time for 1 inch drop = 9.32 minutes.
DESIGN CRITERIA
A single family residence has been proposed for this
site for year-round use. The residence will have a total of
five (5) bedrooms, and will be equipped with a garbage disposer
and automatic clothes washing-machi.ne., Thus design criteria
for calculations are:
DESIGN CRITERIA - continued
2 persons/bedroom
75 gallons/person/day - average flow
+20% absorption area for garbage disposer
+40% absorption area for automatic washer
+25% absorption area for dosing tank
+30% absorption area for reducing subsidence
Maximum flow: 150% of average flow
CALCULATIONS
3
A = QjE where A = minimum absorption area (sq.ft.)
5 Q = maximum quantity of sewage flow (gal/day)
T = percolation rate (min/inch)
Q= 5 x 2 x 75 x 1.5 = 1125 gal/day
A = Q T = 11259 . 3 2 = 687 s ft.
5 +137 sq. ft. (disposal +20%)
+275 sq. ft. Nasher +40%)
-172 sq. ft. (dosing -25%)
+206 sq. ft. (subsidence +30%)
1,133 sq. ft. absorption trench
From Table 5, a minimum area of 165 sq. ft. per bedroom
is required. (165 x 5 = 825 sq. ft., which is less than 1133
sq. ft.) Minimum area of the absorption trench is 1,133 sq. ft,
use 1,140 sq. ft.
If Advanced Drainage Systems, Inc, SB2 10-inch gravelless
leach bed tubing is used, one lineal foot of pipe is required
for each three square feet of absorption trench; thus 380 lineal
feet is required.
From Table 4 (Section 4.07.01 of the Eagle County Regu-
lations), a 1,500 gallon septic tank is required.
4
SEPTIC SYSTEM RECOMMENDATIONS
Based on the preceding calculations, it is recommended
to install a 1500-gallon compartmented septic tank followed
by a minimum 1140 square foot seepage trench. The seepage
trench should lie a minimum of 10 feet from all property lines,
and 20 feet from the proposed residence. An inspection of the
system should be made by a representative of the Eagle County
Environmental Health Department prior to backfilling. The
installation and material specifications must comply with
the Eagle County Individual Sewage Disposal System Regulations.
An an alternate to the standard 1140 square foot seepage
trench, 380 lineal feet of 10-inch diameter "gravelless" leach
bed tubing (as manufactured by Advanced Drainage Systems, Inc.)
could be embedded in the native soils of the site. Due to
the remoteness of the site, this alternate would probably be
cost-effective.
A dosing chamber with dual alternating siphons will be
installed. The dosing chamber will allow for periodic high
rate discharge to alternating portions of the drainage field
instead of a slow trickle into the field. This would prolong
the life of the drainage field.
CONCLUSIONS
This report has been prepared for the exclusive use of
Kensington Land Investment Partners for the specific application

The absorption area within the mound system can either be a bed or a
series of trenches. Beds are typically used for single homes or other
small systems because they are easier to construct. The shape of the
bed, however, depends on the permeability of the natural soil and the
slope of the site. In most instances, a rectangular bed with the long
axis parallel to the slope contour is preferred to minimize the risk of
seepage from the base of the mound. If the natural soil has a percola-
tion rate slower than 60 min/in. (24 min/cm), the bed should be made
narrow and extended along the contour as far as possible (see Figure 7-
12). In soils with percolation rates faster than 60 min/in. (24
min/cm) , the bed can be square if the water table is greater than 3 ft
(0.9 m) below the natural ground surface (4)(25)..

RE: The Divide at Cordillera, Filing 2, Lot 48
Physical Address: 0115 Alhambra Place
Ms. Fawcett:
Enclosed please find a permit application for the alteration of the individual sewage disposal
system, a check in the amount of $150 for the permit application fee, a site plan entitled "The
Divide at Cordillera, Filing No. 2, Lot 48, Septic System Alteration," and a letter from Hepworth-
Pawlak Geotechnical, Inc. reporting on the profile hole for the proposed relocation.
Ms. Kathy Scott and myself have both spoken with you previously in regards to the above
referenced file. As you may recall, the septic system on Lot 48 encroaches into the neighboring
lot and building envelope (Lot 47). We are proposing to relocate the portion of the septic system
encroaching Lot 47 back onto Lot 48. According to our phone conversations, you stated that a
percolation test would not be necessary, only a soil profile in the area where the relocated septic
system would be located would be required. The enclosed letter from Hepworth-Pawlak
Geotechnical, Inc. satisfies this requirement.
We did not redesign the existing septic system, we are simply proposing to backfill the absorption
trench that is encroaching onto the adjacent lot and construct a new absorption trench adjacent to
the existing Lot 48 septic system. Please refer to "The Divide at Cordillera, Filing No. 2, Lot 48,
Septic System Alteration," for the proposed improvements.

Subject: Profile Hole at Proposed Septic Disposal Area, Lot 48, Filing 1, Divide
at Cordillera, Eagle County, Colorado
Dear Alan:
As requested, a representative of Hepworth-Pawlak Geotechnical, Inc. observed a
profile hole dug in the proposed septic disposal area at the subject site on December 21,
2000. The work was performed in accordance with our agreement for professional
services with you, dated December 4, 2000.
The proposed disposal area is located in the northern part of the lot and below the
driveway entrance to the residence. The terrain is steep down to the west and vegetated
with thick sagebrush and some oak brush. About 1 to 1 1/2feet of snow covered the site
at the time of our field work.
The profile hole was dug with a Bobcat 341 backhoe to its practical excavation depth
limit of 81/2 feet. The hole was dug in the upper southern part of the proposed disposal
area. The soils exposed in the pit consisted of 3 feet of topsoil above rock fragments in
a silty clay matrix. The lower portion of the pit could be highly weathered
claystone/siltstone. No free water was encountered in the excavation and the soils
were slightly moist.
If there are any questions or if we may be of further assistance, please let us know.
