PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study for a proposed residence to be located
on Lot 107, Wild Rose Drive, lronbridge 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 an evaluation of subsidence potential 017. Lot 107 and
presented our findings in a report dated February 25. 2005, Job No 105 1 1 5-1
An exploratory boring was drilled on the lot to obtain information on the subsurface
conditions. The results of the field exploration 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
encounte>fed.
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 about 2,500 to
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 loadings, typical of the proposed type of construction.
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.
JobNo. 10! 196-1
SITE CONDITIONS
The lot is located in the downhill, eastern part of the development and was vacant at the
time of our field exploration. Wild Rose Drive borders the lot to the west 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
The ground surface is relatively flat and slopes gently down to the northeast. Up to a few
inches 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 gravel terrace alluvium of the
Roaring Fork River. The alluvium is predominantly a clast-supported deposit of rounded
gravel, cobbles and boulders up to about 3 feet in size in a silty sand matrix that extended
to a depth of 28 feet on the lot.
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. Voids were not encountered in the bedrock to the drilled depth of 481A feet
and the potential for subsidence due to dissolution of the evaporite throughout the service
life of the residence, in our opinion, is low_ Our previous report dated February 25, 2005
should be referenced for the complete findings of the subsidence potential evaluation.
FIELD EXPLORATION
The field exploration for the project was conducted on February 22, 2005. 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-Pawlak Geotechnical, Inc.
Job No. 101 196-1
G e
n
Sampling of the subsoils to evaluate engineering properties was not practical due to the
difficult drilling conditions encountered with augers.
SUBSURFACE CONDITIONS
A graphic kw of the subsoil profile encountered in the boring is shown on Figure 2. The
subsoils consist of elatively dense, slightly silty sandy grave] with cobbles and boulders
(terrace alluvium) down to the drilled depth of 4/2 feet. Drilling in the dense terrace
alluvium with auger equipment was difficult due to the cobbles and boulders and drilling
refusal was encountered in the deposit. No free water was encountered in the boring at the
time drilling and the subsoils were slightly moist.
FOUNDATION BEARING CONDITIONS
Silt and clay (debris fan) soils typical of the area were not encountered in the boring but
could be at shallow depth in other parts of the lot. Foundations that extend down to the
dense terrace alluvium would have moderate bearing capacity and low settlement risk.
Spread footings placed on the natural terrace alluvium should be feasible for building
support with relatively Iow settlement potential.
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.
JobNo. 10] 196-1
-4-
1) Footings placed entirely on the natural dense terrace alluvium can he
designed for an allowable bearing pressure of 3,000 psf. Based on
experience. we expect initial settlement of footings designed and
constructed as discussed in this section will be about 1 inch or less.
2) The footings should have a minimum width of 16 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 grade 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 Retaining Walls" section of this report.
5) Any existing fill, topsoil and loose or disturbed soils should be remo' ed
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 lateral
earth pressure computed on the basis of an equivalent fluid unit weight of at least 50 pcf
for backfill consisting of the on-site granular soils. Cantilevered retaining structures
which are separate from the residence and can be expected to deflect sufficiently to
mobilize the full active earth pressure condition should be designed for a lateral earth
pressure computed on the basis of an equivalent fluid unit weight of at least 40 pcf for
backfill consisting of the on-site granular soils.
Job No. 101 196-1
Gtech
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°%0 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 should be 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 pressur6
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 0.5 for footings placed on gravel soils.
Passive pressure of compacted backfill against the sides of the footings can be calculated
using an equivalent fluid unit weight of 350 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.
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 where present have variable

settlement 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 laver of free -
draining grave] should be placed beneath basement level stabs to facilitate drainage This
material should consist of minus 2 -inch aggregate with at ]east 30% retained on the No 4
sieve and Jess than 2T°/a 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.
UNDERDRAIN SYSTEM
Although free water was not encountered during our exp]oration, it has been our
experience in the area that local 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 Tess) 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 level 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
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 11/2 feet deep.

SURFACE DRAINAGE
The following drainage 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 90% of the maximum standard
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 slope of 6 inches in the first ] 0 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 dowrispouts and drains should discharge well beyond the limits of all
backfill.
5) Landscaping which requires regular heavy irrigation should be located at
least 5 feet from foundation walls.
LIMITATIONS
This study has been conducted in accordance with generally accepted geotechnical
engineering principles and practices in this area at this time. We make no warranty either
express or implied. The conclusions and recommendations submitted in this report are
based upon the data obtained from the exploratory boring drilled at the location indicated
on Figure 1, the proposed type of construction and our experience in the area. Our
services do not include determining the presence, prevention or possibility of mold or
other biological contaminants (MOBC) developing in the future. if the client is
concerned about MOBC, then a professional in this special field of practice should be

consulted. Our findings include interpolation and extrapolation of the subsurface
conditions identified at the exploratory boring and variations in the subsurface conditions
may not become evident until excavation is performed. If conditions encountered during
construction appear different from those described in this report_ we should be notified so
that re-evaluation of the recommendations may be made.
This report has been prepared for the exclusive use by our client for design purposes. We
are not responsible for technical interpretations by others of our information As the
project evolves. we should provide continued consultation and field services during
construction to review and rnonitoi the implementation of our recommendations, and to
verify that the recommendations have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein. We recommend on-site observation of excavations and foundation
bearing strata and testing of structural fill by a representative of the geotechnical
engineer.

1. The exploratory boring was drilled on February 22, 2005 with a 4—inch diameter continuous flight power
auger.
2. The exploratory boring location was measured approximately by pacing from features shown on the site
plan provided.
3. The exploratory boring elevation was not measured and the log of exploratory boring is drawn to depth.
4. The exploratory boring location should be considered accurate only to the degree implied by the method
used.
5. The lines between materials shown on the exploratory boring log represent the approximate boundaries
between materia! types and transitions may be gradual
6. No free water was encountered in the boring at the time of drilling. Fluctuation in water level may
occur with time.
