The project site is shown on Figure l . The purpose of the study was to develop recommendations for the foundation design. The study was conducted in accordance with our agreement for geotechnical engineering services to Cerise Ranch dated July 26, 2004. CTL/Thompson, Inc. previously conducted a preliminary geotechnical study for the Cerise Ranch Development and presented their findings in a report dated January 27, 2000, Job No. GS 2933. A field exploration program consisting of exploratory borings was conducted 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 single story, wood frame structure over a crawlspace with an attached garage. Garage floor will be slab -on -grade. Grading for the structure is assumed to be relatively minor with cut depths between about 2 to 3 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. Job No. 104 579 G1,113 -tech -9 - SITE CONDITIONS The lot was vacant at the time of our field exploration and is Iocated south (downhill) of Lark Spur Drive. The ground surface is relatively flat with a gentle slope down to the southwest. There is about 3 feet of elevation difference across the building area. A drainage ditch is located to the south of the building envelope and was flowing at the time of our field exploration. Vegetation consists of grass and weeds. Eagle Valley Evaporite is visible in the steep hills along the northern boundary of the subdivision. SUBSIDENCE POTENTIAL Bedrock of the Pennsylvanian age Eagle Valley Evaporite underlies the Cerise Ranch development. These rocks are a sequence of gypsiferous shale, fine-grained sandstone and siltstone with some massive beds of gypsum and limestone. There is a possibility that massive gypsum deposits associated with the Eagle Valley Evaporite underlie portions of the lot. Dissolution of the gypsum under certain conditions can cause sinkholes to develop and can produce areas of localized subsidence. Sinkholes were not observed in the immediate area of the subject lot. No evidence of cavities was encountered in the subsurface materials; however, the exploratory borings were relatively shallow, for foundation design only. Based on our present knowledge of the subsurface conditions at the site, it cannot be said for certain that sinkholes will not develop. The risk of future ground subsidence on Lot 3 throughout the service life of the proposed residence, in our opinion, is low; however, the owner should be made aware of the potential for sinkhole development. If further investigation of possible cavities in the bedrock below the site is desired, we should be contacted. FIELD EXPLORATION The field exploration for the project was conducted on July 26, 2004. Two exploratory borings were drilled at the locations shown on Figure 1 to evaluate the subsurface conditions. The borings were advanced with 4 -inch diameter continuous flight augers powered by a truck -mounted CME -45B drill rig. Hand -slotted, 11/4 -inch diameter PVC Job No. 104 579 GecPttch pipe was installed in the borings to the depths shown on Figure 2 for water level readings. The borings were logged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with 1% inch and 2 inch I.D. spoon samplers. The samplers were 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 Logs of Exploratory Borings, Figure 2. The samples were returned to our laboratory for review by the project engineer and testing. SUBSURFACE CONDITIONS Graphic logs of the subsurface conditions encountered at the site are shown on Figure 2. The subsoils consist of about 1 foot of topsoil overlying generally soft, slightly sandy silty clay. Relatively dense sandy gravel with cobbles and probable small boulders was encountered beneath the clay at depths of 111/2 and 13 feet below the ground surface. Drilling in the dense gravel soils with auger equipment was difficult due to the cobbles and boulders and drilling refusal was encountered in the deposit. Laboratory testing performed on samples obtained from the borings 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 shallow drive sample of the clay, presented on Figure 4, indicate high compressibility under conditions of loading and wetting. The laboratory testing is summarized in Table 1. . Free water was encountered in the borings between depths of 2 and 31/2 feet at the time of drilling. Water Ievels of 5 and 3 feet were measured in Borings 1 and 2, respectively, when checked 4 days following drilling. The subsoils were moist to wet below the water level. Job No. 104 579 GecPtech -4 - FOUNDATION BEARING CONDITIONS The upper clay soils encountered at the site are compressible under light loading and are soft below a depth of about 2 feet. Excavations should be kept relatively shallow in order to avoid the underlying soft wet soils. Based on the planned excavation depths and building layout, it does not appear feasible to adequately limit cut depths to avoid encountering soft soils and groundwater. Lightly loaded, shallow spread footings placed on the upper soils will have a risk of excessive settlement and building distress. The settlement risk for shallow spread footings can be reduced by surcharge loading the building site with soil for adequate time to allow the fine-grained soils to compress prior to foundation construction. Another method to limit foundation settlement potential would be to support the residence on a deep foundation such as pipe piles or micropiles which extend down into the sandy gravel soils encountered at depths of 111/2 and 13 feet in the borings. If the deep foundation alternative is selected, we should be contacted for the design review and additional analysis as needed. Free water was encountered in the borings between 3 and 5 feet below the ground surface when checked 4 days followed drilling. Groundwater levels could rise during seasonal peak runoff and field irrigation. The ground floor or crawlspace grade should be kept at least 2 feet above the high groundwater level. Ventilation and a moisture barrier should be provided in the crawlspace. DESIGN RECOMMENDATIONS SOIL SURCHARGE Surcharge loading should be applied for adequate time to allow the fine-grained soils at the site to compress prior to spread footing foundation construction. The surcharge should be placed over the entire building area and be at least 10 feet deep. Structural frlI needed to achieve design subgrade levels, such as for the garage slab, should be placed prior to adding the surcharge loading. The subgrade should be prepared by removing any vegetation or topsoil, and compacting to at least 90% of the standard Proctor density. Stabilization of soft subgrade areas could be needed prior to placing the structural fill. Job No. 104 579 G 17tech -5 - Structural fill planned for building support that extends to above existing ground surface can be included in the surcharge soil depth. The surcharge should be placed as early in the construction schedule as possible to allow time for the fine-grained soils to compress, and for a period of at least 3 months. The building pad settlement could be monitored by a level survey on a regular basis in order to determine the point at which the settlement has substantially stopped. After the surcharge loading has been removed, spread footings can be used to support the residence as described in the recommendations presented below. Long term settlements of the footings for this alternative are expected to be about 1 inch or less. SPREAD FOOTINGS The design and construction criteria presented below should be observed for a spread footing foundation system after the surcharge soil has been removed. 1) Footings placed on the upper natural clay soils should be designed for an allowable bearing pressure of 1,000 psf. Based on experience, we expect settlement of footings designed and constructed as discussed in this section will be up to about 1 inch and differential across the building. 2) The footings should have a minimum width of 20 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 15 feet. Foundation walls acting as retaining structures. should also be designed to resist a lateral earth pressure corresponding to an equivalent fluid unit weight of at least 55 pcf. 5) Topsoil and any loose or disturbed soils should be removed to expose the relatively firm natural soils. The subgrade in the footing area should then be moisture adjusted and Iightly compacted as needed. The excavation Job No. 104 579 Gtech -6 - should be no deeper than 2 to 3 feet below existing ground surface to avoid encountering soft soils and/or groundwater. 6) A representative of the geotechnical engineer should observe all footing excavations prior to concrete placement to evaluate bearing conditions. FLOOR SLABS The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab - on -grade construction. The upper fine-grained soils are compressible and there could be some long term slab distress. The soil surcharge used for a spread footing foundation should essentially mitigate the slab settlement risk. To reduce the effects of some differential movement, non-structural 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 interior slabs for 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. A vapor barrier should be used to prevent moisture migration up through the floor slab. 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 relatively dry soils devoid of vegetation, topsoil and oversized rock. UNDERDRAIN SYSTEM Free water was encountered during our exploration at relatively shallow depths and 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 crawlspace areas, be protected from wetting and hydrostatic pressure buildup by an underdrain system. Job No. 104 579 GeS-tech 7 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 I V2 feet deep. SURFACE DRAINAGE The 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. 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 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 soils to reduce surface water infiltration. 4) Roof downspouts and drains should discharge well beyond the Iimits 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 express or implied. The conclusions and recommendations submitted in this report are Job No. 104 579 Ptech -8 - based upon the data obtained from the exploratory borings drilled at the locations 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 borings 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 bearing strata and testing of structural fill by a representative of the geotechnical engineer.

NOTES: 1. Exploratory borings were drilled on July 26, 2004 with a 4—inch diameter continuous flight power auger. 2. Locations of exploratory borings were measured approximately by pacing from property corner stakes. Elevations of exploratory borings were measured by instrument level and refer to the Bench Mark shown on Figure 1. The exploratory boring locations and elevations should be considered accurate only to the degree implied by the method used. The lines between materials shown on the exploratory boring logs represent the approximate boundaries between material types and transitions may be gradual. Water level readings shown on the logs were made at the time and under the conditions indicated. Fluctuation in water level may occur with time.
