consist of 3 to 4 feet of loam sand with a 9 inch gravel bed be 15 feet wide by 65 in length.
A 1 foot cap of clayey soil will be placed on the mound. The mound would be located
approximately 120 feet to the southeast from the center of the building envelope in the
shallow draw.
Estimate Costs
1. Septic Tank - 1500 Auto Siphon $2370.00
Delivery 250.00
2. Mound 85 feet X 37 feet — 600 cubic yards(est.)
$5000.00
3. Miscellaneous materials (est.) $500.00
Installation (est.) $6000.00
Estimated cost $14,120.00
WHITE WATER TREATMENT SYSTEM
The White Water Treatment System consists of an aerobic unit, a dosing chamber and an
absorption system consisting of irrigation emitters. The absorption field should be
approximately 50 feet by 50 feet. The mound should be approximately 4 to 5 feet in
height. The mound will contain a 6-inch thick gravel layer containing rows of irrigation
type emitters on 1/2 inch plastic tubing.
The White Water Treatment System treats the wastewater to a point where the absorption
field is much cleaner than the wastewater from a septic tank. The aerobic unit treats the
wastewater influent mixing the influent in the chamber with organisms formed by the
decomposition of organic materials. Mixing is accomplished by releasing compressed air
from the bottom of the tank to mix the biomass and other solids and to supply oxygen for
waste degradation. An advantage to this system is that should surfacing of wastewater
occur down gradient from the mound absorption field, the wastewater would be cleaner
and less displeasing odors would be noticed.

SAND FILTER SYSTEMS
Sand Filter systems are becoming popular in many locations along the outlining Denver.
Metropolitan Area. They involve a septic tank and either and a single pass or
recirculating sand filter. The septic system for this site involves a 1500 gallon septic tank
and a mound absorption field. The advantage to this system is that should surfacing of
wastewater occur down gradient from the mound absorption field, the wastewater would
be cleaner and less displeasing odors would be noticed.
Estimated Costs
1. 1500 gallon septic tank(include delivery) $2620.00

EXECUTIVE SUNUUARY
The project consists of the development and construction of a single family residence on Lot
48, Cordillera Subdivision Filing No. 24, in Eagle County, Colorado. We anticipate that the proposed
residence will consist of a two story wood frame residence with a basement.
The site is located on Aspen Meadows Road in Bearden Meadows. Two soil test borings were
performed to help determine the foundation design parameters, and we exploratory bores for septic
system investigation. The site has a topsoil layer of approximately 0.5 feet in thickness. The
subsurface soils at the site consist of cobble, sandy SILT, silty SAND and SAND to depths of
approximately 2 to 3 feet. At 2 to 4 feet, variable weathered SANDSTONE was encountered which
was underlain by SANDSTONE BEDROCK.
The foundations at the site may be designed for a bearing pressure of 4000 psf for footings
located in the SANDSTONE BEDROCK. A minimum foundation bearing pressure of 500 psf is
recommended.
SCOPE
This report presents the results of a Geotechnical Investigation for the proposed residence to
be constructed on Lot 48, Cordillera Subdivision Filing No. 24, in Eagle County, Colorado. The
investigation was performed by advancing soil test borings, obtaining soil samples for laboratory
testing, and presenting our findings in this report.
The purpose of this foundation exploration is to evaluate the soil for foundation support, and
the engineering characteristics of the foundation materials, and to provide criteria from a geotechnical
perspective, for use by the owner in preparing foundation design, grading design, and drainage plans.
SITE LOCATION AND DESCRIPTION
The site is an undeveloped lot located at Lot 48, Cordillera Subdivision Filing No. 24 in
Bearden Meadows at the Ranch at Cordillera near Edwards, Colorado. The site is bounded by
partially wooded and wooded lots. The western boundary consists of Aspen Meadows Road. The site
slopes toward the east at gradients estimated to range from 5 to 40 percent. Vegetation on the site
consists of Aspen trees and the ground surface contains a grass root mat.

SITE INVESTIGATION
. The subsurface exploration included a site reconnaissance by an Inter -Mountain Engineering
personnel and the drilling of two soil test borings to observe the subsurface soil profile and obtain soil
samples for laboratory testing. The soils test borings. were performed by a truck mounted CME 55
drill rig to the depths indicated in the Summary of Test Borings. The test boring locations were
established in the field by estimating right angles and pacing distances from site features. The
approximate locations of the test borings are illustrated on the Site Plan in the Appendix, refer to
Drawing No. 1. The Appendix also contains Summary of Test Borings presenting the information
which was obtained in the subsurface exploration, a key to the terms used in the Summary of Test
Borings, and a brief description of the procedures used.
The ground surface elevation shown on the Summary of Test Borings was interpolated from
the site plan and should be considered to be approximate.
SUBSURFACE AND GROUNDWATER CONDITIONS
The generalized soil stratigraphy is presented below. The stratum symbols and solid lines
which are used to illustrate the various strata break on the Summary of Test Borings are approximate
as the transitions between soil types may occur suddenly or relatively gradual.
Two soil test borings were performed to help determine the foundation design parameters, and
we exploratory bores for septic system investigation. The site has a topsoil layer of approximately 0.5
feet in thickness. The subsurface soils at the site consist of cobbly, sandy SILT, and SAND to depths
approximately 2 to 3 feet. At 2 to 4 feet variable weathered SANDSTONE was encountered above a
silty SANDSTONE BEDROCK.
No measurable groundwater was present at the time the soil test borings were completed. No
long-term ground water observations were made.
Laboratory sampling for swell -consolidation characteristics was not possible.
5
The underlying bedrock is mapped as the Maroon Formation which is described on the
Charles S. Robinson in 1975 maps as a grayish -red to moderate reddish -orange SILTSTONE and
silty SANDSTONE; grayish -red, pale red and pale red -purple arkosic SANDSTONE.
PROPOSED CONSTRUCTION
The project site consists of the construction of a single family residence on the site. The
residence is to be of wood frame construction with concrete slab on grade construction for the ground
floor. We anticipate that the residence will be a two-story structure with a walk out basement.
Foundation wall loading is anticipated to range from 1 to 5 kips per linear foot, and isolated column
loading are anticipated to range from approximately 5 to 25 kips.
FOUNDATION RECOMMENDATIONS
Based upon the results of field explorations and the laboratory testing, we recommend that
conventional spread footing foundation system be used. The foundations may be designed for a
bearing pressure of 4000 psf for footings bearing on undisturbed sandstone bedrock, and approved fill
materials compacted to the recommendations provided herein. A minimum foundation bearing
pressure of 500 psf based upon dead load is recommended.
At this pressure, settlements are anticipated to be within tolerable limits for wood frame
construction, provided the improvements in the bearing soils will be made as discussed herein. The
footing excavations should be relatively smooth, free of debris, organics, loose soil, frost, and standing
water. Any over -excavations should be backfilled and compacted to 100 percent within 2 percent of
optimum moisture as determined by a Standard Proctor Test (ASTM D-698). A representative of this
office should be contacted to inspect the foundation excavation to verify that the soil conditions are the
same as those anticipated in this report.
0
After, all of the final grading is completed, the bottom of the footings should be covered with a
minimum of 48 inches of backfill for frost protection.
Voids left by the removal of cobbles in the bottom of the footing excavation should be filled
. with lean concrete or a granular soil with a maximum particle size of 3 inches compacted to 100
percent of Standard Proctor Density (ASTM D-698), within 2 percent of optimum moisture.
i
SLAB CONSTRUCTION
The on -site soils, exclusive of Topsoil and Organics are suitable to support lightly loaded slab -
on -grade construction. All excavations made for the foundations under proposed slab -on -grade areas
must be properly backfilled with suitable material compacted to a minimum of 95 percent of the
maximum Standard Proctor Density (ASTM D-698). Backfill placed beneath slab -on -grade floors
should be installed at -1 to +3% of optimum moisture content. The on -site soils, exclusive of topsoil
and organics are suitable for use as backfill. Before the backfill is placed, all water and loose debris
should be removed from the excavations.
Prior to the construction of concrete floors, the undisturbed subgrade, free from topsoil and
organics, should be proof rolled with a loaded rubber -tired loader or similar equipment to densify the
near surface soils. To reduce the chance of damage to shallow utilities, special care should be taken in
areas where underground utilities are present.
All columns should be isolated from concrete slabs -on grade to prevent movement of the
columns due to slab movement. The voids surrounding the columns should be expansion joint
materials with a minimum 1/2" clearance.
The bedrock formation occasionally contains clayey layer which swell when wetted. If the
clayey materials are encountered in the foundation excavation, the footing should be stepped through
the clayey materials to bear on the sandstone.
GROUNDWATER AND DRAIN SYSTEM
While no groundwater was reported in the soil test borings at the time the field investigation
was conducted, it is possible that seasonal variations will cause fluctuations, or for a water table to be
present in the upper soils during the spring months, or after :prolonged periods of rain. A foundation
perimeter drain as detailed on Figure No. 8 is recommended to reduce the risk of surface water
infiltrating the footing subsoils. The foundation perimeter drain should daylight to a down gradient
point.
The foundation should be well reinforced and rigid enough to withstand differential
settlements. Walls retaining earth should be designed to resist an equivalent fluid pressure of 35 pcf for
an "active" case assuming a level drained backfill condition. For "at rest" conditions such as basement
walls, an equivalent fluid pressure value of 50 pcf may be used for "at rest" conditions.
CRAWL SPACE COVER
When moist soils are encountered in the excavation, the ground surface in crawl space areas
should be covered with an impervious moisture barrier sealed against the footings. This will help to
reduce humidity in the crawl space area.
BACIUML AND SURFACE DRAINAGE
The foundation soils encountered in portions of the site must be prevented from being wetted
after construction. The backfill placed around the foundation walls should be methodically compacted
to help reduce settlement after completion of construction. The top one foot of the backfill material
must be relatively impervious. The on -site soils, exclusive of Topsoil and Organics are suitable for use
as backfill.
8
Foundation wall backfill should be moistened or dried to near its optimum moisture content
and compacted to at least 90 percent of the maximum Standard Proctor Density. Structural backfill
should be compacted to at least 95 percent of the maximum dry density as determined by the Standard
Proctor method of test (ASTM D 698).
Surface water running toward the structure from up slope areas should be diverted around and
away from the building by means of lined drainage swales or other similar measures.
The final grade should have a positive slope away from the foundation walls on all sides. A
minimum of 12 inches in the first 10 feet is recommended. Down spouts and sill cocks should
discharge into splash blocks that extend beyond the limits of the backfill or a minimum distance of at
least 5 feet from the foundation wall. The use of long downspout extensions in place of splash blocks
is advisable.
EXCAVATION
The superficial soils at the site should be easily excavated with conventional backhoe-
trackhoe equipment. Should the proposed construction require excavation into the shallow
bedrock, then the prospective owner should be aware that some additional effort will probably be
necessary. We do not anticipate that the excavation operations will require blasting, however
some puematic hammering with a trackhoe may be necessary.
SEPTIC SYSTEM
The site was evaluated with respect to the potential of installing a septic system at the site.
Weathered Bedrock was found in the building enveloped at depths ranging from 2 to 3 feet in Borings
B4 and B-2, respectfully. The PROFILE boring, located approximately 140 feet to the southeast had
i
approximately 4 feet of silty SAND overlying a SANDSTONE BEDROCK. Three percolation holes
were bored at points surrounding the PROFILE HOLE indicated 1.5 , to 2,5 feet of soil above the
SANDSTONE BEDROCK.
The shallow bedrock condition would not allow for a conventional bed or row absorbtion field.
Alternatives include a mound septic absorbtion field, aeration system, or a sand filter system.
LAWN IRRIGATION
Do not install sprinkler systems next to foundation walls, porches or patio slabs. If sprinkler
systems are installed, the sprinkler heads be aligned so that the spray from the heads, under full
pressure, does not fall on foundation walls or within five feet of foundation walls, porches, or patio
slabs. Lawn irrigation must be controlled and no flooding or ponding of water should be performed.
If the future owners desire to plant next to foundation walls, porches or patio slabs, and are
willing to assume the risk of structural damage, etc., then it is advisable to plant only flowers and
shrubbery (no lawn) of varieties that require very little moisture. These flowers and shrubs should only
be hand watered.
MISCELLANEOUS
The recommendations provided herein are based on experience in the area and from the on -site
field exploration. The information obtained from the field exploration and laboratory testing reflects
subsurface conditions only at the specific locations at the particular times designated. Subsurface
conditions at other locations and times may differ from the conditions at these locations. The extent of
10
any variations between the test borings may not appear evident until excavation is performed.
However, only minor variations are expected. If during construction conditions appear to be different,
this office should be advised so reevaluation of the recommendations may be made.
This report has been prepared for the exclusive use of Robert J. Smith for the specific
application to the proposed residence to be located on Lot 48, Cordillera Subdivision Filing 24, Eagle
County, Colorado.
The findings and recommendations of this report have been prepared in accordance with locally
accepted professional engineering standards for similar conditions at this time. There is no other
warranty, either expressed or implied.

Attention: Laura Fawcett
ICE: Individual Septic System installation
Lot 48, Cordillera Filing No. 24
Dear Laura,
As per our telephone conversation on Friday August 6, 1999 we will be making the
following revisions to our design for the proposed septic system for the subject lot:
1. T$e leach field will be. enlarged to provide a bottom trench absorption area of
1975 square :feet. The final dimensions and number of lateral runs will be
submitted with a revised drawing for the system following further site
investigation to ensure the field adheres to the required setbacks_
2. The clay cap as indicated on the drawing will be removed and the system will be
backfilled with native material to provide an opportunity for evapotranspiration.
3. A Miraf. Filter Fabric will be installed over the gravel surrounding the perforated
pipe to prevent any fines from entering and clogging the system_
4. A mote will be added to ensure final grading will convey surface runoff around the
leach geld to avoid any infiltration into the system.
These revisions have been conveyed verbally to representatives of Long's Excavating
and final leach field .dimensions will be provided based on further site investigation.
Based on these revisions we are requesting the issuance of an individual septic system
installation permit. If you have any questions or any further comments please contact the
undersigned at this office.
Respectfully,
Tony knovan

RE: Individual Septic System Installation
Lot 48, Cordillera Filing No. 24
Ladies and Gentlemen:
On August 6, 1999 a representative of Inter -Mountain Engineering Ltd. (I1VIE) visited the
subject site to observe the installation of an individual septic disposal system. A test pit
was excavated to determine the depth of underlying bedrock to ensure a minimum 4 foot
separation was maintained between the bottom of the leach field and the bedrock. The
test pit was excavated to approximately 8 feet and no bedrock was encountered. Based
upon our review, it appears that the septic system was installed in substantial compliance
with the design and revisions made by Eagle County Environmental Health Department.
Per the request of Eagle County Environmental Health Department, attached is an as -built of
the leach field and all appurtenant tanks and observation ports.
If you have any additional questions, please do not hesitate to contact the undersigned at this
office.
