In order to understand the scope of the work intended under a permit application and expedite the
issuance of a permit it is important that complete information be provided. When reviewing a plan
and it's discovered that required information has not been provided by the applicant, this will result
in the delay of the permit issuance and in proceeding with building construction. The owner or
contractor shall be required to provide this information before the plan review can proceed. Other
plans that are in line for review may be given attention before the new information may be reviewed
after it has been provided to the Building Department.
Please review this document to determine if you have enough information to design your
project and provide adequate information to facilitate a plan review. Also, please consider
using a design professional for assistance in your design and a construction professional for
construction of your project. Any project with more than ten (10) occupants requires the plans
to be sealed by a Colorado Registered Design Professional.
To provide for a more understandable plan in order to determine compliance with the building,
plumbing and mechanical codes, applicants are requested to review the following checklist prior to
and during design. Applicants are required to indicate appropriately and to submit the

PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study for a proposed residence to be Iocated
on Lot 129, Silver Mountain Drive, Ironbridge Development, Garfield County, Colorado.
The project site is shown on Figure 1. The purpose of the study was to develop
recommendations for the foundation design The study was conducted as a supplement to
our agreement for geotechnical engineering services to L.B. Rose Ranch, LLC dated July
24, 2003. We previously conducted subsurface exploration to evaluate the collapse
potential on the non -irrigated debris fan areas within the development and presented the
findings in a report dated September 10, 1998, Job No. I97 327.
An exploratory boring was drilled on the lot to obtain information on the subsurface
conditions. Samples of the subsoils obtained during the field exploration were tested m
the Laboratory to determine their classification, compressibility or swell and other
engineering characteristics. The results of the field exploration and laboratory testing
were analyzed to develop recommendations for foundation types, depths and allowable
pressures for the proposed building foundation. This report summarizes the data obtained
during this study and presents our conclusions, design recommendations and other
geotechnical engineering considerations based on the proposed construction and the
subsurface conditions encountered.
PROPOSED CONSTRUCTION
The specific building on the lot had not been determined at the time of this study. The
proposed residence will generally be a 1 or 2 story, wood frame structure between about
2,500 and 3,000 square -feet in size. Ground floor will be slab -on -grade and/or structural
over a crawlspace. A basement level may be provided. Grading for the structure is
assumed to be relatively minor with cut depths between about 3 to 8 feet. We assume
relatively light foundation Ioadings, typical of the proposed type of construction.
Job No. 101 196-1
-2 -
If building loadings, location or grading plans change significantly from those described
above, we should be notified to re-evaluate the recommendations contained in this report.
SITE CONDITIONS
The lot is located in the western, uphill part of the development and was vacant at the
time of our field exploration. Silver Mountain Drive borders the lot to the northeast and
Wild Rose Drive borders the Iot to the northwest as shown on Figure 1. The roadway and
underground utility construction to the lot are complete. Minor overlot grading during
subdivision development consists of shallow cuts and fills across most ofthe lot. The
ground surface is relatively flat and slopes gently down to the northeast. Up to 1 foot of
snow covered the lot at the time of our field exploration.
GEOLOGY
The geologic conditions were described in our previous report conducted for planning and
preliminary design of the subdivision development, dated October 29, 1997, Job No. 197 "
327. The surficial soils on the lot mainly consist of sandy silt and clay debris fan deposits
overlying terrace gravel alluvium of the Roaring Fork River. The alluvium is
predominantly a clast-supported deposit of rounded gravel, cobbles and boulders up to 3
feet in size in sand and silty sand matrix.
The underlying bedrock consists of the Eagle Valley Evaporite which contains gypsum
and is generally associated with scattered sinkhole development in the Roaring Fork
River valley. The potential for subsidence due to dissolution of the evaporite throughout
the service life of the residence, in our opinion, is low. If further evaluation of the
sinkhole potential on the Iot is desired, we should be contacted.
Job No. 101 196-1
-3 -
FIELD EXPLORATION
The field exploration for the project was conducted on. December 10, 2004. An
exploratory boring was drilled at the location shown on Figure 1 to evaluate the
subsurface conditions. The boring -was advanced--with-4-inch diameter continuous flight
augers powered by a truck -mounted CME -45B drill rig. The boring was logged by a
representative of Hepworth-Pawiaic Geotechnical, Inc.
Samples of the subsoils were taken with a 2 inch 1.D. spoon sampler The sampler was
dd.,. en into the subsoils at various depths with blows from a 140 pound hammer falling 30
inches. This test is similar to the standard penetration test described by ASTM Method
D-1586. The penetration resistance values are an indication of the relative density or
consistency of the subsoils. Depths at which the samples were taken and the penetration
resista.ncevalues are shov,n on the Loa of Exploratory' 3oring, Figure 2. The samples
were returned to our laboratory for review by the project engineer and testing.
SLTBSURFACE CONDITIONS
A graphic log of the subsoil profile encountered in the boring is shown on Figure 2. The
subsoils, below about Y2 foot of topsoil, consist of 15/2 feet of stiff to very stiff, slightly
sandy to sandy silt and clay overlying relatively dense silty sandy gravel and cobbles with
boulders (terrace alluvium) down to the drilled depth of 17 feet. Drilling in the terrace
alluvium with auger equipment was difficult due to the cobbles and boulders and drilling
refusal was encountered in the deposit.
Laboratory testing performed on samples obtained from the boring included natural
moisture content, density and percent finer than No. 200 sieve (silt and clay fraction)
gradation analyses. Results of swell -consolidation testing performed on a relatively
undisturbed drive sample, presented on Figure 4, indicate Iow compressibility under
existing moisture conditions and Iight loading and a low expansion potential after
wetting. Consolidation testing performed on samples taken from nearby lots typically
Job No. 101 196-1

show that the natural silt and day soils collapse under a constant load after wetting.. The
laboratory testing is summarized in Table I.
No free water was encountered in the boring at the time of drilling and the subsoils were
slightly moist
FOUNDATION BEARING CONDITIONS
The upper silt and clay (debris fan) soils typically have tow bearing capacity and low to
moderate settlement potential. The expansion potential indicated by the swell -
consolidation test can be neglected iri the foundation design. Foundations which extend
down to the dense terrace alluvium would have moderate bearing capacity and low
settlement risk. Spread footings placed on the upper debris fan soils should be suitable
for support of relatively lightly- loaded structures with some settlement risk. mainly if the
bearing soils become wetted. The settlement potential and risk of distress can be reduced
by supporting the building on a stiffened slab (mat) foundation, or ground improvements,
.such as removal and replacement of the native soils compacted to at ]east 95% of standard
Proctor density at a moisture content at to 2% above optimum. We expect the ground
modifications would be Iimited to the upper 5 to 10 feet. If a deep foundation or ground
improvements are proposed, we should be contacted.
DESIGN RECOMMENDATIONS
FOUNDATIONS
Considering the subsurface conditions encountered in the exploratory boring and the
nature of the proposed construction, we recommend the building be founded with spread
footings bearing on the natural subsoils.
The design and construction criteria presented below should be observed for a spread
footing foundation system.
Job No 101 196-1
AHP. _
-5-
1) Footings placed on the undisturbed natural subsoils should be designed for
an allowable bearing pressure of 1,200 psf. Based on expenence, we
expect initial settlement of footings designed and constructed as discussed
in this section will be up to about 1 inch. Due to the variable settlement
potential of the debris fan soils, additional differential movement of about
1 inch could occur if the bearing soils become wetted.
)
The footings should have a minimum width of20 inches for continuous
walls and 2 feet for isolated pads
3) Exterior footings and footings beneath unheated areas should be provided
with adequate soil cover above their bearing elevation for frost protection
Placement of foundations at least 36 inches below exterior erade is
typically used in this area.
4) Continuous foundation walls should be reinforced top and bottom to span
local anomalies such as by assuming an unsupported length of at least 12
feet. Foundation walls acting as retaining structures should also be
designed to resist lateral earth pressures as discussed in the "Foundation
and Retailing Walls" section of this report.
5) Any existing fill, topsoil and loose or disturbed soils should be removed
and the footing bearing level extended down to the firm natural soils. The
exposed soils in footing area should then, be moistened and compacted.
6) A representative of the geotechnical engineer should observe all footing
excavations prior to concrete placement to evaluate bearing conditions.
FOUNDATION AND RETAINING WALLS
Foundation walls and retaining structures which are laterally supported and can be
expected to undergo only a slight amount of deflection should be designed for a IateraI
earth pressure computed on the basis of an equivalent fluid unit weight of at least 55 pcf
for backfill consisting of the on-site fine-grained soils. Cantilevered retaining structures
which are separate from the building and can be expected to deflect sufficiently to
mobilize the full active earth pressure condition should be designed for a_lateral earth
Job No. 101 196-1
-6 -
pressure computed on the basis of an equivalent fluid unit weight of at least 50 pcf for
backfill consisting of the on-site fine-grained soils.
All foundation and retaining structures should be designed for appropriate hydrostatic and
surcharge pressures such as adjacent footings, traffic, construction materials and
equipment. The pressures recommended above assume drained conditions behind the
walls and a horizontal backfill surface. The buildup of water behind a wall or an upward
sloping backfill surface will increase the lateral pressure imposed on a foundation wall or
retaining structure. An underdrain should be provided to prevent hydrostatic pressure
buildup behind walls.
Backfill should be placed in uniform lifts and compacted to at least 90% of the maximum
standard Proctor density at a moisture content near optimum. Backfill in pavement and
walkway areas should be compacted to at least 95% of the maximum standard Proctor
density. Care should be taken not to overcompact the backfill or use large equipment
near the wall, since this could cause excessive lateral pressure on. the wall. Some
settlement of deep foundation wall backfill should4be expected, even if the material is
placed correctly, and could result in distress to facilities constructed on the backfill.
The lateral resistance of foundation or retaining wall footings will be a combination of the
sliding resistance of the footing on the foundation materials and passive earth pressure
against the side of the footing. Resistance to sliding at the bottoms of the footings can be
calculated based on a coefficient of friction of 0.35. Passive pressure of compacted
backfill against the sides of the footings can be calculated using an equivalent fluid unit
weight of 300 pcf. The coefficient of friction and passive pressure values recommended
above assume ultimate soil strength. Suitable factors of safety should be included in the
design to limit the strain which will occur at the ultimate strength, particularly in the case
of passive resistance. Fill placed against the sides of the footings to resist lateral loads
should be compacted to at least 95% of the maximum standard Proctor density at a
moisture content near optimum.
Job No 101 196-1

FLOOR SLABS
The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab -
on -grade construction. The upper silt and clay soils have variable settlement/heave
potential when wetted under load and there could be some post -construction slab
movement if the subgrade soils become wet. To reduce the effects of some differential
movement. floor slabs should be separated from all bearing walls and columns with
expansion joints which allow unrestrained vertical movement. Floor slab control joints
should be used to reduce damage due to shrinkage cracking. The requirements for joint
spacing and slab reinforcement should be established by the designer based on experience
and the intended slab use. A minimum 4 inch layer of free -draining gravel should be
placed beneath basement level slabs to facilitate drainage. This matenal should consist of
minus 2 inch aggregate with at Ieast 50% retained on the No. 4 sieve and less than 2%
passing the No 200 sieve.
All fill materials for support of floor slabs should be compacted to at least 95% of
maximum standard Proctor density at a moisture content near optimum. Required fill can
consist of the on-site soils devoid of vegetation, topsoil and oversized rock.
UNTDERDRAIN SYSTEM
Although free water was not encountered during our exploration, it has been our
experience in the area that Iocal perched groundwater can develop during times of heavy
precipitation or seasonal runoff. Frozen ground during spring runoff can create a perched
condition. We recommend below -grade construction, such as retaining walls, crawlspace
and basement areas, be protected from wetting and hydrostatic pressure buildup by an
underdrain system. An underdrain should not be provided around shallow foundations (3
feet deep or less) and garage areas.
The drains should consist of drainpipe placed in the bottom of the wall backfill
surrounded above the invert level with free -draining granular material. The drain should
be placed at each Ievel of excavation and at least 1 foot below lowest adjacent finish
grade and sloped at a minimum 1% to a suitable gravity outlet. Free -draining granular
Job No. 101 196-!
-8 -
material used in the underdrain system should contain less than 2% passing the No. 200
sieve, less than 50% passing the No. 4 sieve and have a maximum size of 2 inches. The
drain gravel backfill should be at least 1'/2 feet deep. An impervious membrane such as
20 mil PVC should be placed beneath the drain gravel in a trough shape and attached to
the foundation wall with mastic to prevent wetting of the bearing soils.
SURFACE DRAINAGE
The following dramage precautions should be observed during construction and
maintained at all times after the building has been completed:
1) Inundation of the foundation excavations and underslab areas should be
avoided during construction.
2) Exterior backfill should be adjusted to near optimum moisture and
compacted to at least 95% of the maximum standard Proctor density in
pavement and slab areas and to at least gni of the maximum sta. da:J
Proctor density in landscape areas.
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 scope of 6 inches in the first 10 feet in unpaved
areas and a minimum slope of 3 inches in the first 10 feet in paved areas.
Free -draining wall backfill should be capped with about 2 feet of the on-
site, fine-grained soils to reduce surface water infiltration.
4) Roof downspouts and drains should discharge well beyond the limits of all
backfill.
5) Landscaping which requires regular heavy irrigation should be located at
least 10 feet from foundation walls. Consideration should be given to use
of xeriscape to reduce the potential for wetting of soils below the building
caused by irrigation.
