Lot 19, Filing 6, Elk Springs Subdivision, Garfield County, Colorado Dear Mr. Cooke: As requested, Hepworth-Pawlak Geotechnical, lnc_ performed a subsoil study for design of foundations
at the subject site_ The study was conducted in accordance with our agreement for geotechnical engineering services to Caribou Construction dated March 23, 2006_ The data obtained and
our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Hepworth-Pawlak Geotechnical, Inc_, previously performed a
preliminary geotechnical study for Filings 6 through 9, Elk Springs (formerly Los Amigos Ranch PUD) and reported our findings on February 14, 1997,job No_ 197617_ Proposed Construction:
The proposed residence will be one story wood frame construction above a basement with an attached garage and located on the site as shown on Figure 1_ Basement and garage floors will
be slab-on-grade_ Cut depths are expected to range between about 3 to 8 feel Foundation loadings for this type of construction are assumed to be relatively light and typical of the proposed
type of construction. Ifbuilding conditions or foundation loadings are significantly different from those described above, we should be notified to re-evaluate the recommendations presented
in this report_ Site Conditions: Lot 19 is located on the west (downhill) side of Wood Nympth Lane on a rolling mesa_ Vegetation consists of sage brush, grass and weeds and scattered
pinion Parker 303-841-7119 • Colorado Springs 719-633-5562 • Siiverthome 970-468-1989
-2 -and juniper trees. The ground surface slopes gently down to the southwest at a grade of about 10 percent in the building area. Scattered basalt cobbles are visible on the ground
surface. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits at the approximate locations shown on Figure 1. The logs of the
pits are presented on Figure 2. The subsoils encountered, below about one foot 0 f topsoil, consist of basalt cobbles and boulders in a silt and sand matrix. Results 0 f a gradation
analysis performed on a sample of gravel in a silt and sand matrix(minus 5 inch fraction) obtained from the site are presented on Figure 3. No free water was observed in the pits at
the time of excavation and the soils were slightly moist to moist. F oundatiou Recommendations: Considering the subsoil conditions encountered in the exploratory pits and the nature
of the proposed construction, we recommend spread footings placed on the undisturbed natural soil designed for an allowable soil bearing pressure of 2,500 psf for support of the proposed
residence. The silt and sand matrix soils tend to compress after wetting and there could be some post-construction foundation settlement. Footings should be a minimum width of 16 inches
for continuous walls and 2 feet for columns. Utility trenches and deep cut areas may require rock excavating techniques such as chipping or blasting. Loose and disturbed soils encountered
at the foundation bearing level within the excavation should be removed and the footing bearing level extended down to the undisturbed natural soils. Voids created from boulder removal
at footing grade should be filled with a structural material such as road base compacted to 95 percent standard Proctor density at a moisture content near optimum or concrete. Exterior
footings should be provided with adequate cover above their bearing elevations for frost protection. Placement of footings at least 36 inches below the exterior gradc is typically used
in this area. 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

::c:.:t:.:oi :.:n::... 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 freedraining gravel should be placed beneath basement level slabs to facilitate drainage. This
material should consist of minus 2 inch aggregate with less than 50% passing 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 fiI! can consist of the on-site soils devoid of vegetation, topsoil
and oversized rock. Underdrain System: Although free water was not encountered during our exploration, 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. The drains should consist of drainpipe placed in the bottom
of the wall backfill surrounded above the ~~ level with free-draining granular materiaL The drain should be placed at each level of excavation and at least I foot below lowest adjacent

following drainage precautions should be observed during construction and maintained at all times after the residence has been completed: 1) Inundation of the foundation excavations
and underslab areas should be ? avoided during construction, Drying could increase the expansion potential of the soils, 2) Exterior backfill should be adjusted to near optimum moisture
and compacted to at least 95% of the maximuID standard Proctor density in pavement and slab 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 feet of the on-site, finer graded 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 of3 inches in
the first 10 feet in pavement and walkway areas, A swale may be needed uphill to direct surface runoff around the residence, 4) Roof dovvnspouts and drains should discharge well beyond
the limits of all backfilL 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 ex.press or implied, The conclusions and recommendations submitted in this report are based upon the data obtained from the exploratory pits excavated at the
locations indicated on Figure I and to the depths shown on Figure 2, the proposed type of construction, and our ex.perience in the area, Our services do not include determining the presence,
prevention or possibility of mold or other biological contaminants (MOB C) developing in the future, If the client is concerned about MOBC, then a professional in Job No, 106 0268
-5 -this special field of practice should be consulted. Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory pits 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 at once so 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 monitor
the implementation of our recommendations, and to veri!}' that the recommendations have been appropriately interpreted. Significant design changes may require additional analysis or
modifications to the recommendations presented herein. We recorrunend on-site observation of excavations and foundation bearing strata and testing of structural fill by a representative
of the geotechnical engIneer. If you have any questions or if we may be of further assistance, please let us know. Respectfully Submitted, HEPWORTH -PAWLAK GEOTECHNICAL, INC. -/C;;~;-~
