Box 2068 Eagle, Colorado 81631 Job No. 195 343 Subject: Subsoil Study for Foundation Design and Percolation Test, Proposed Residence, 1660 Salt Creek Road, Eagle County, Colorado. Dear Mr. Overend: si k rlxr, Z As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study and percolation test for foundation and septic disposal designs at the subject site. The study was conducted in accordance with our agreement for geotechnical engineering services to you dated July 13, 1995. The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Proposed Construction: The proposed residence will be a 11/2 story log structure above a walkout basement level and located on the site as shown on Fig. 1. Ground floor will 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 to moderate. W 0 P u m� ? l�avc- 4 v If building conditions, location or foundation loadings are significantly different from those described above, we should be notified to reevaluate the recommendations presented in this report. Site Conditions: The proposed building site is located uphill of an overhead power line in undisturbed native terrain. The ground surface is moderately to steeply sloping generally down to the north. Vegetation consists of sage brush, grass and weeds. The proposed septic disposal area is located in a fallow irrigated field covered with grass and weeds. The test locations on the lot are shown on Fig. 1. An existing residence is located in the northern part of the lot. Charlie Overend November 6, 1995 Page 2 Subsurface Conditions: The subsurface conditions at the proposed building site were evaluated by excavating two exploratory pits at the approximate locations shown on Fig. 1. The logs of the pits are presented on Fig. 2. The subsoils encountered, below about 11/2 to 2 feet of topsoil, consist mainly of stiff slightly sandy to sandy clay. _ In Pit 1, porous sandy clay with gravel was encountered below about 31h feet. Results of swell -consolidation testing performed on relatively undisturbed samples of the stiff and porous clays, presented on Figs. 3 and 4, indicate low compressibility under existing low moisture conditions and light loading. The stiff clay samples showed a minor expansion potential when wetted and moderate compressibility after loading. The porous clay sample showed a moderate collapse (settlement under constant load) when wetted and high compressibility under additional loading. No free water was observed in the pits at the time of excavation and the soils were slightly moist to moist. Foundation Recommendations: Considering the subsoil conditions encountered in the exploratory pits and the nature of the proposed construction, spread footings placed on the undisturbed natural soil designed for an allowable soil bearing pressure of 1,500 psf can be used for support of the proposed residence. The_ soils exhibit erratic hydro swell or compression potential which could results in post construction settlements if the bearing soils were to become wet. Footings should be a minimum width of 18 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 to expose undisturbed natural soils. The native subgrade should then be compacted to at least 95 % of standard Proctor density at a moisture content near optimum. 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 14 H-P GEOTECH Charlie Overend November 6, 1995 Page 3 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 55 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. The soils may settle or heave when 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 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 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 may 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, crawl space - and basement areas, be protected from wetting and hydrostatic pressure buildup .by an underdrain system. H-P GEOTECH Charlie Overend November 6, 1995 Page 4 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 1'/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: 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. Free -draining wall backfill should be capped with at least 2 feet of the on -site 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 H-P GEOTECH Charlie Overend November 6, 1995 Page 5 3 inches in the first 10 feet in pavement and walkway areas. A Swale will 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 use of xeriscape next to the building to prevent potential subsurface wetting from irrigation. Percolation Test: A profile pit and three percolation tests were conducted at the designated area (refer to Fig. 1) for evaluation of an infiltration septic disposal system. The profile pit location is shown on Fig. 1 and the log is shown on Fig. 2. The percolation test results are presented in Table II. Based on our findings, the tested site is suitable for an infiltration septic disposal system. Limitations: This report has been prepared in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no other 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, 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. H-P GEOTECH Charlie Overend November 6, 1995 Page 6 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 soil engineer.
