Ihe.purpose .. of.the .. study_was.tode:v.elop _______________________ , ---------···-- reconunendations for the foundation design. The study was conducted in accordance with our agreement for geotechnical engineering services to Iron bridge Homes, LLC dated June 22, 2007. We previously performed a preliminary geotechnical study for this area of the Phase 2 subdivision development and presented our findings in a report dated May 31, 2005, Job No. 105 115-4. We also performed observation and testing of compaction during the infrastructure and Jot grading construction and presented those findings in daily reports under Job No. 106 0367. 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 in 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 proposed residence will be a 2-story, wood frame structure with a walkout basement level. Ground floors will be slab-on-grade. 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. 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 ---··The·lot-is-hJcated·onthe uphill; southeastern sideofB'enrGtasiOidJiiCelYnotne·soutlfeasr-·· --·------- side of the Mountain Cottages part of Phase 2. The underground utilities to the lot and the roadway construction are complete. Overlot grading during subdivision development consists of relatively shallow cuts and fills. The 1 6'h Hole of the golf course borders the southeast side of the lot. The ground surface has been benched 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 40 feet below ground surface in the area ofLot 174. The underlying bedrock consists of the Eagle Valley Evaporite which contains gypsum deposits and is generally associated with scattered sinkhole development in the Roaring Fork River valley. A sinkhole was observed prior to the subdivision development in Fairway 16 about 200 feet south of Lot 174. The sinkhole was backfilled during construction of the golf course. Voids have not been encountered in borings drilled into the bedrock near Lot 174 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 20, 2007.

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 hanuner 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 Jog of the subsoil profile encountered in the boring is shown on Figure 2. The subsoils consist of about 6 feet of compacted silty sandy clay fill and 14 feet of stiff to very stiff, sandy silt overlying dense, slightly silty sandy gravel, cobbles and boulders (terrace alluvium) down to the drilled depth of20Yz 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 fill material 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 finer than sand size gradation analyses. Results of swell-consolidation testing performed on a relatively undisturbed drive sample of the silt soil, presented on Figure 4, indicate low compressibility under existing low moisture condition and light loading and a low to moderate collapse potential (settlement under Job No. 107 0486 -4- constant load) when wetted. The sample showed moderate compressibility under additional loading. The laboratory test results are summarized in Table l. No free water was encountered in the boring at the time drilling or when checked three day later and the subsoils were slightly moist. FOUNDATION BEARING CONDITIONS The upper silt (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 soils 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 1 to 2 inches could occur if the debris fan soils are wetted. Job No. 107 0486 -5- 2) 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 grade is typicallyused-inihisarea:;--·------------------·---------· ---·---· · ··· · · · 4) Continuous foundation walls should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 14 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 pcf for 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. 107 0486 -6- 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. ··· B!!ckfilhlroulttbeplaclldiYrtmifoM lifts ·and· compacted to ·aneasl90o/Ooflliemaximum -----------·-· standard Proctor density at a moisture content near optimmn. 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 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 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 of300 pcf The coefficient of friction and passive pressure values recommended above assmne 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 maximmn standard Proctor density at a moisture content near optimum. FLOOR SLABS The natural on-site soils and compacted fill are suitable to support lightly loaded slab-on- grade construction. The upper silt 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 allow unrestrained vertical movement. Floor slab con(roljoints should be_ used to rc:Jd\lce Job No. !07 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 free-draining gravel should be placed beneath . basementJevel.slabs to .facilitate drainage. This material should consist ofminus 2-inch aggregate with at least 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. UNDERDRAlN 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 and basement areas, 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 1 foot below lowest adjacent finish grade and sloped at a minimum 1% 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 than 50% passing the No. 4 sieve and have a maximum size of2 inches. The drain gravel backfill should be at least 1 Yz feet deep. 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 completed: . l) Inundation of the foundation excavations and underslab areas should be 2) 11voiJied during construction. . .. . . . . .. .. .. . .. . . . . 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 12 inches in the first 10 feet in unpaved areas and a minimum slope of 3 inches in the first I 0 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 I 0 feet from foundation walls.
