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_£orgeotechnical 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. 197 327. 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 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 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 loadings, typical of the proposed type of construction. Job No. WI 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. Wild Rose Drive borders the lot to the southeast 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 of the 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 lot is desired, we should be contacted. 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 Job No. 101 196-1 -3 - 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. 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 Iaboratory 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, below about '/z foot of topsoil, consist of stiff to very stiff, slightly sandy to sandy silt and clay with occasional gravel lenses down to the drilled depth of 26 feet. Based on other nearby borings, we expect dense gravel alluvium to be below the silt and clay soils at a depth of about 30 to 35 feet. 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 low compressibility under existing low moisture conditions and a minor collapse potential (settlement under a constant load) when wetted. The sample showed moderate compressibility with increased loading after wetting. The laboratory testing is summarized in Table 1. No free water was encountered in the boring at the time of drilling and the subsoils were slightly moist. Job No. 101 196-1 GtV5oec,, -4 - FOUNDATION BEARING CONDITIONS The potential for the subsoils to collapse is consistent with our previous findings for the non -irrigated areas of the development. The subsurface conditions and laboratory test results indicate that the debris fan soils generally have low to moderate collapse potential that decreased with depth. There is a risk of settlement and distress to the building, driveway and utilities founded on the relatively dry debris fan deposits if the subsoils were to become wetted. The magnitude of settlement will depend on the depth and extent of wetting, and the structure loading. Lightly loaded spread footings placed on the natural soils should be suitable for support of the residence with a risk of settlement and distress if the bearing soils become wetted. Precautions to prevent wetting of the bearing soils need to be taken. These include: 1) proper placement and compaction of backfill; 2) positive backfill slopes next to foundations; 3) restricted landscape irrigation and/or use of xeriscape; and 4) gutters to prevent roof runoff near the building. Extensive wetting such as from water line leaks and heavy irrigation could result in excessive settlements and distress. 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 least 95% of standard Proctor density at a moisture content at to 2% above optimum. We expect the ground modifications would be limited to the upper 5 to 10 feet. If other foundation types and subgrade treatment methods 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. Job No. 101 1 961-1 5 The design and construction criteria presented below should be observed for a spread footing foundation system. 1) Footings placed on the undisturbed natural subsoils 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 up to about 1 inch. Additional differential settlement of about 1 to 2 inches or more could occur if the bearing soils become wetted. 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 typically used in this area. 4) The foundation should be constructed in a "box Tike" configuration rather than isolated footings. The foundation walls should be heavily reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 15 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 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 alI 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 Iola No. 101 196-1 1 1 1 1 1 1 -6- 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 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 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 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 Job No. 101 196-1 7 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 soils are compressible when wetted under load and there could be some post -construction settlement and distress if the subgrade soils become wetted. 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 material should consist of minus 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. 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 Job No. 101 196-1 8 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 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. 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 Developing and maintaining positive drainage throughout the life of the residence is critical to limiting potential settlement and distress to the building. The following drainage precautions should be observed during construction and maintained at all times after the building has been completed: 1) Uncontrolled wetting 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 dram away from the foundation in all directions. We recommend a minimum slope 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. Job No. 10.1 196-1 -9- 4) Roof downspouts and drains should discharge well beyond the limits of ail 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. 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 monitor 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 Job No. 101 196-1 -10 - bearing strata and testing of structural fill by a representative of the geotechnical engineer.
