The study was conducted in accordance with our agree:t cat for geptechnical engineering services to you dated Mareb 28, 2003, The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report- Evaluation of potential geologic hazard impacts at the site are beyond the scope of this study. Proposed Construction: The proposed residence will be one or two story wood frarne construction over a possible basement or crawlspa.ce with an attached garage and located on the site as shown on Figure 1. Ground floors in the basement and ,garage are proposed to be slab -on -grade. Cut depths are expected to range between about 3 to 8 Feet. Foundation loadings for this type of construction are assumed to be relatively light and typical of the proposed type of construction. The, septic disposal system is proposed to be located downhill and west of the residence. If building conditions or foundation loadings are si-rdficanily different from those described above, we should be notified to re-evaluate the recommendations presented in this report. Site Conditions: The lot is located on the south side of Blue Creek Trail. The ground surface in ihe- building area slopes moderately steep down to the south with about 12 feet of elevation difference across the building footprint. The lot is vegetated with scattered pinon trees, sagebrush grass and weeds. Numerous cobbles and small boulders are exposed on the ground surface.

The logs of the pits are presented on Figure 2. The subsoils encountered, below about 1 foot of topsoil, consist of basalt cobbles and boulders in a silty sand matrix. Results of a 'gradation analysis performed on a sample of the gravel (minus 6 inch fraction) obtained from the site are presentee! on Figure 3. The laboratory test results are summarized in Table 1. No free water was observed in the pits at the time of excavation and the sails were slightly moist to moist. Foundation 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 2,000 psf for support of the proposed residence. The 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. Loose and disturbed soils encountered at the foundation bearing level within the excavation should be removed and the footing bearing level extended dawn to the undisturbed natural soils. Voids created from boulder removal at the footing bearing level should be filled with properly compacted structural material such as 3/4 inch road base. Exterior footings should be provided with adequate cover above their bearing elevations for frost protection. Placement of footings at least 42 inches below the exterior grade 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 10 feet, Foundation walls acting as retaining structures should be designed to resist a lateral, earth pressure based on an equivalent fluid unit weight of at least 50 pcf for the on -site soil as backfill. Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support lightly loaded slab -on -grade construction. To reduce the effects of some differential movement, floor slabs should he separated from all bearing walls and columns with expansion joints which allow unrestrained vertical movement. Floor slab control join. is 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 tha 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 less than 50% passing the No. 4 sieve and less than 2% passing the No. 200 sieve. Job #f 103 215 nF�r•r. � Jun -I 3-03 04:29pm From -Eagle County Community Development 970 $28 7185 T-962 P.004/011 F-142 Lighthill Development ApdI 25, 2003 Page 3 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 an -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 C7 pressure buildup by an underdrain system. 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 11�1'o to a suitable gravity outlet. Free -draining granular material used in the underdrain system should contain less than 296' passing the No. 200sieve, less than 50% passing the No. 4 sieve and have a maximum size of 2 inches. The drain gravel backfill should be at least feet deep. Surface Drainage: The following drainage precautions should be observed during construction and maintained at all times after the TesideDoe has been compIeted- 1) Inundation of the foundation excavations and undprslab areas should be avoided during construction. 2) Exterior backfill should be adjusted tQ near optimum moisture and compacted to at least 95% of the maximum standard Proctor density in pavement and slab areas and to at least 90010 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 minim -um slope of 03 inches in the first 10 feet in pavement and walk -way areas. A swale may be neeeded uphill to direct surface runoff around the residence. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. Job # 103 215 111- 1 - ---- -- -I .

Consideration should be given to the use of xeriscape to limit poteritia) wetting of soils below the building caused by irrigation_ Percolation Testing. Percolation tests were conducted on April 15, 2003 to evaluate the feasibility of an infiltration septic disposal system at the site. One profile pit and three percolation holes were du; at the locations shown on Figure X. The test holes (nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow backhoe pits and were soaked with water one day prior to testing. The soils exposed in the percolation holes are similar to those exposed in the Profile Pit shown on Figure 2 and consist of basalt cobbles and boulders in a silty sand matrix. The percolation test results are presented in Table 2_ Based on the subsurface condizions encountered and the percolation test results, the tested area should be suitable for a conventional infiltration septic disposal system. JIMitat ong: This study has been conducted in accordance with generally accepted geotechnical ertgxrteerxug principles and practices in this area at this time. We make no warranty either expressed 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 1, the ,proposed type of construction and our experience in the area. 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 ethers 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_ loin # 103 215 C_1491ech Ti It.l - -i , - OCX7{ , C'o T r r1- 7MOM T R •Goal C rill KiTY Pf dt J PP7i f TN PRiaE : 5 Jun-1 3-03 04:29pm From -Eagle County Community Development 970 328 7185 T-962 P-006/011 F-142 Lighthill Development April 25, 2.003 Page 5 If you have any questions or if we may be of further assistance., please let us know.
