The study was conducted in required accordance with our agreement for geotechnical engineering services to you dated June 16, 1998. The agreement was verbally amended by you to include additional percolation testing. 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 on the site are beyond the scope of this study. Proposed Construction: The proposed residence will be a 1 and 2 story wood frame structure cut into and stepped down the hillside. The proposed building location on the site is shown on Fig. 1. Ground floors will be slab -on- grade. Cut depths are expected to range between about 3 to 5 feet. Foundation loadings for this type of construction are assumed to be relatively light and typical of the proposed type of construction. The on -site septic disposal system.was originally planned about 30 feet downhill to the northwest of the proposed residence and then moved to about 125 feet south of the residence where more favorable percolation rates were found. If building conditions or foundation loadings are significantly different from those described above, we should be notified to re- evaluate the recommendations presented in this report. Site Conditions: The lot is vacant and located in variable, hilly terrain. The building site is on a strongly sloping to moderately steep, southwesterly facing hillside with grades ranging from about 10 to 20 %. Elevation difference across the proposed residence is about 15 feet. There are several coalescing gullies along the west - northwest sides of the lot that were dry at the time of our field work. The lot is vegetated with sagebrush, grass, weeds and scattered juniper and pinion trees. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits at the building site and one profile pit in the original planned septic disposal area, at the approximate locations shown on Fig. 1. The logs of the pits are presented on Fig. 2. The subsoils encountered, below about 1 to 1 feet of topsoil, consist of a layer of medium dense clayey sandy gravel with shale fragments • Joel Cotton July 10, 1998 Page 2 about 1 to 3 feet deep overlying weathered claystone shale bedrock in Pit 1 and very stiff sandy clay with shale fragments in Pit 2. Results of swell - consolidation testing performed on relatively undisturbed samples of the sandy clay subsoils, presented on Fig. 3, indicate low to moderate compressibility under existing moisture conditions and light loading. One sample (Pit 2 at 7 feet) showed a low expansion potential when wetted under a constant light surcharge. Results of a gradation analysis performed on a sample of the clayey gravel with shale fragment subsoils (minus 11 inch fraction) obtained from the site are presented on Fig. 4. The laboratory testing is summarized in Table I. No free water was observed in the pits at the time of excavation and the soils and bedrock were slightly moist to moist. Foundation Recommendations: Considering the subsurface conditions encountered in the exploratory pits and the nature of the proposed construction, we recommend spread footings placed on the undisturbed natural soils or shale bedrock designed for an allowable bearing pressure of 3,000 psf for support of the proposed residence. Due to the expansion potential, the footings should also be designed to impose a minimum dead load pressure of 600 psf. The soils and bedrock may tend to swell after wetting and there could be some post - construction foundation movement if the bearing materials become wetted. Precautions should be taken to prevent wetting of the building. 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 down to the undisturbed natural soils or shale bedrock. Exterior footings should be provided with adequate cover above their bearing elevations for frost protection. Placement of footings at least 36 inches below the exterior grade is typically used in this area. Continuous foundation walls should be well reinforced top and bottom to span local anomalies and better withstand the effects of some differential movement such as by • assuming an unsupported length of at least 12 feet. Foundation walls acting as retaining structures should also be designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at least 50 pef for the on -site granular soil as backfill. The granular soils should be selectively stockpiled during excavation for re -use as foundation wall backfill. Floor Slabs: The natural on -site soils and shale bedrock, exclusive of topsoil, are suitable to support lightly loaded slab -on -grade construction. There is a risk of slab heave if expansive materials below the slab were to become wetted. Slab -on -grade construction may be used provided precautions are taken to limit the risk of slab heave and a risk of movement is accepted by the owner. Interior partition walls bearing on slabs -on -grade should be provided with slip joints so that if the slab heaves the movement is not transmitted to the upper structure. To reduce the effects of some differential movement, floor slabs should be separated from all bearing walls and • H -P GEOTECH Joel Cotton July 10, 1998 Page 3 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 less than 50% passing 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 to above optimum. Required fill can consist of the on -site more granular soils devoid of vegetation, topsoil and oversized rock, or a suitable imported granular material. Underdrain System: Although free water was not encountered during our exploration, it has been our experience in the area were clay soils are present and bedrock is shallow, that local perched groundwater can develop during times of heavy precipitation or seasonal runoff. Frozen ground during spring runoff can also 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 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 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 or 30 mil PVC should be placed beneath the drain gravel in a trough shape and attached to the foundation wall with mastic to help prevent wetting of the bearing materials. Surface Drainage: Positive surface drainage is an important aspect of the project to limit the potential for wetting below the building. The following drainage precautions should be observed during construction and maintained at all times after the residence has been completed: 1) Excessive wetting or drying of the foundation excavation materials should be avoided during construction. Drying could increase the expansion potential of the soils and shale bedrock. 2) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95% of the maximum standard Proctor density in H -P GEOTECH Joel Cotton July 10, 1998 Page 4 pavement and slab areas and to at least 90% of the maximum standard Proctor density in landscape areas. Granular 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 minimum slope of 3 inches in the first 10 feet in pavement and walkway areas. A swale may be needed uphill to direct surface runoff around the residence. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Landscaping which requires regular heavy irrigation should be located at least 10 feet from the building. Consideration should be given to the use of xeriscape to limit potential wetting due to irrigation. Percolation Testing: Percolation tests were conducted at the site to evaluate the feasibility of an infiltration septic disposal system. One profile pit and three percolation holes (P -1, P -2, P -3) were dug at the origihal proposed location shown on Fig. 1. 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 by the client one day prior to testing. The soils exposed in the percolation holes are similar to those exposed in the Profile Pit shown on Fig. 2 and consist of sandy clay with angular rock fragments. The percolation test results presented in Table II indicated rates from nil to about 240 min/in. Due to the slow percolation rates, a second site to the south of the residence was tested for percolation rates. For the southern site (P -4, P -5, P -6), the percolation tests were conducted in 8 inch diameter auger holes, prepared by the client. The results, also presented in Table II, indicate percolation rates at this site between about 12 and 30 minutes per inch based on an average of the last two readings. Based on the assumed subsurface conditions and the percolation test results at the southern site, this area should be suitable for a conventional infiltration septic disposal system. We recommend the infiltration area be oversized due to the variable percolation rates. Garfield County may require additional subsoil investigation and percolation testing at the selected site for the system design. 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 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 Fig. 1, and to the depths shown on Fig. 2, the proposed type of construction and our experience in the area. Our findings include interpolation and H -P GEOTECH Joel Cotton • July 10, 1998 Page 5 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 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.
