We previously perfonned a preliminary geotechnical study for this area of the Phase 2 subdivision development and presented our fmdings in a report dated May 31, 2005, Job No. 105 115-4. We also perfonned observation and testing of compaction during tbe infrastructure and lot grading construction and presented tbose findings in daily reports under Job No. 106 0367. An exploratory boring was drilled on the lot to obtain infonnation on the subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to detennine tbeir classification, compressibility or swell and other engineering characteristics. The results of tbe 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 proposed residence will be a 2-story, wood frame structure. Ground floors will be structural above crawlspace in the residence area and slab-on-grade in the garage. Grading for the structure is assumed to be relatively minor witb cut deptbs between about 3 to 4 feet. We assume relatively light foundation loadings, typical of tbe proposed type of construction. Job No. 107 0486 -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· · T!fenoris-located on the downhill, eastern sideofRiveiBeiidWayjusno the north of the· Mountain Cottages part of Phase 2. Theundergrotiiid utilities to thelotand the roadway construction are complete. Overlot grading conducted during subdivision development appears to consist of shallow fills. The 17'h Hole of the golf course borders to the east of the lot. The ground surface is relatively flat and slopes gently down to the east. Vegetation consists of sparse grass and weeds. GEOLOGY The geologic conditions were described in our previous report conducted for planning and preliminary design of the overall subdivision development dated October 29, 1997, Job No. 197 327. The surficial soils on the lot mainly consist of sandy silt debris fan deposits overlying 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 was encountered to depths of about 25 to 30 feet below ground surface in the area. 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. An apparent sinkhole was observed along the south side ofRiver Bend Way and River Bank Way intersection about 250 feet north of Lot 249. The sinkhole was . excav~tted, backfilled and grouted during construction of the roadway.Voids have not been encountered in borings drilled into the bedrock near Lot 249 and the potential for subsidence due to dissolution of the evaporite throughout the service life of the residence, in our opinion, is low, but the owners of the lot should be aware of the sinkhole potential and the risk of future subsidence. Job No. 107 0486 -3- FIELD EXPLORATION The field exploration for the project was conducted on July 19, 2007. An exploratory boring was drilled at the location shown on Figure·]· to evaluate the subsurface conditions. The boring was advanced with 4-inch diameter continuous flight augers ·p6we-re<ny·a truck"mounted ·cME~45B· drill rig:· Tile boring was logged bya representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with a 2 inch I.D. spoon sampler. The sampler was driven 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 resistance values are shown on the Log of Exploratory Boring, Figure 2. The samples were returned to our laboratory for review by the project engineer and testing. SUBSURFACE CONDITIONS A graphic log of the subsoil profile encountered in the boring is shown on Figure 2. The subsoils consist of about 2 feet of compacted silty sandy clay fill and 20 feet of medium stiff, sandy silt and clay overlying dense, slightly silty sandy gravel, cobbles and boulders (terrace alluvium)down to the drilled depth of23 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. The existing fill111aterial was placed during the subdivision development and monitored during construction for compaction by Hepworth-Pawlak Geotechnical. Laboratory testing performed on samples obtained from the boring included natural moisture content and density and fmer than sand size gradation analyses. Results of swell-consolidation testing performed on a relatively undisturbed drive sample of the silt and clay soil, presented on Figure 4, indicate low compressibility under existing low moisture condition and light loading and a low collapse potential (settlement under Job No. 107 0486 i I I -4- constant load) when wetted. The sample showed moderate compressibility under additional loading. The laboratory test results are sununarized in Table 1. No·free water was encountered in the boring at the time drilling or when checked 4 days later and the subsoils were slightly moist to moist with depth. FOUNDATION BEARING CONDITIONS The upper silt and clay (debris fan) soils typically have low bearing capacity and low to moderate settlement potential under loading when wetted. Foundations that extend down to the dense terrace alluvium would have moderate bearing capacity and low settlement risk. Spread footings placed on the natural soils or compacted fill are recommended for building support with some potential for differential settlement, mainly if the debris fan soils are wetted. 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 or compacted "structural fill. The design and construction criteria presented below should be observed for a spread footing foundation system. I) Footings placed on the undisturbed natural soils or compacted fill should be designed for an allowable bearing pressure of 1,000 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. Additional differential settlement on the order of I inch could occur if the debris fan soils are wetted. Job No. 107 0486 -5- 2) The footings should have a minimwn 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 grade is · ·cypicall'fused-iliiliis·area: · · · 4) Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by asswning 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 vegetation and loose disturbed soils should be removed and the footing bearing level extended down to the firm natural soils or compacted fill. The exposed soils in footing areas 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 55 pcf for backfill consisting of the on-site 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 45 pcffor backfill consisting of the on-site 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 Job No. I 07 0486 -6- walls and a horizontal backfill surface. The buildup of water behind a wall or an upward sloping backfiJI 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.· · · ·Baclffiinmotild be placed iii iiiiifonnlifts·and compacted to at least 90% ofllie maX.imum --·· - 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 wa!J 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 retruning wal! footings will be acombination of the sliding resistance of the footing on the foundation materials and passive earth pressure agrunst the side of the footing. Resistance to sliding at the bottoms of the footings can be calculated based on a coefficient of friction of0.35 for footings placed on fine-grained soils. 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 reconunended 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:csite soils and compacted fill are suitableto support lightly loaded slab-on- grade construction. The upper silt and clay soils 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 . . . ?,l!s>W.lllli:e~!:r!!llie4Y<:J!1ic<!l movement. I'loor slab control j.oints should.be used to reduce Job No. 107 0486 -7- 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 relatively well graded sand and gravel should be placed beneath interior slabs for support. This .material should consist of minus 2-inch aggregate with at least 50% retained on the No.4 sieve and less than 12% passing the No. 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 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 dnring spring runoff can create a perched condition. We recommend below-grade construction such as retaining walls be protected from wetting and hydrostatic pressure buildup by an underdrain system. An underdrain should not be provided around shallow foundations (roughly 3 feet deep or less) and slab- on-grade 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 I foot below lowest adjacent finish grade and sloped at a minimum I% to a suitable gravity outlet or sump and pump. Free- draining granular material used in the underdrain system should contain less than 2% passing the No. 200 sieve, less th;m 50% passing the No.4 sieve and have a maximum size of2 inches. The drain gravel backfill should be at least I Y, feet deep. In silt and clay bearing soil areas, an impervious membrane, such as a 30 mil PVC liner, should be placed in a trough shape below the drain gravel and attached to the foundation wall with mastic to prevent wetting of the bearing soils. Job No. 107 0486 -8- SURF ACE DRAINAGE The following drainage precautions should be observed during construction and maintained at all times after the building has been C()mpleted: 1) Inundation of the foundation excavations and underslab areas should be 2) avoided.during.construction. . ................ _ . . .......... . Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95% of themaximrim 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 minimwn slope of 12 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, such as sod, should be located at least 10 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 figur~:: 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 Job No. 107 0486 -9- 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 .notresp.onsible. for. technical interpr.etations.hy. others. ofoudnformation . .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 verifY that the recommendations have been appropriately interpreted. Significant design changes tnay 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.

The exploratory boring was drilled on July 19, 2007 with a 4-inch diameter continuous flight power auger. 2. The exploratory boring location was measured approximately by pacing from features shown on the subdivision plat drawing. 3. The exploratory boring elevation was not measured and the log of the boring is drawn to depth. 4. The exploratory boring location and elevation 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 material types and transitions may be gradual. 6. No free water was encountered in the boring at the time of drilling or when checked 4 days later. Fluctuation in water level may occur with time. 7.
