Dear Mr. Shapira: 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 Mhay. —I&, 2000 The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Hepworth-Pawlak Geotechnical, Inc. previously performed a preliminary subsoil study and geologic hazards evaluation of the Sopris Mesa Subdivision, report dated October 23, 1997, Job No. 197 495. Proposed Construction: The proposed residence will be a 2 story wood frame structure located on the site as shown on Fig. 1. The lower level will be a walk -out basement with a slab -on -grade floor. 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-septid=isasal system is. proposed--,to.�be located:;to�the�southeast of'the residence. The driveway,,.from Green Meadow Drive to the -residence will- be -gravel surfaced. 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. Builders West LLC June 27, 2000 Page 2 Site Conditions: The lot is vacant and located downhill of Green Meadow Drive. The ground surface in the building area is gently rolling with a strong slope down to the southeast. Elevation difference across the proposed building is about 8 feet. The're—is, an irrigation ditch -to: the.west. of the building, site -that. was :flowing at the time of our field work. The lot is vegetated with grass and weeds. h�} Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits in the building area and one profile pit in the 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/Z to=3 feet of topsoil, consisted -,,of stiff, sandy silty clay. The -clay, -extended to the. depths explored of 7'h to 84eet at Pit 1 and the Profile Pit, respectively, and to a depth af3aboutr6feetat Pt2 where relatively;;dense..basalt gravel and_cobbles with boulders in a sandy clayey silt matrix. was encountered to :the pit depth -of 8 feet. Results of swell -consolidation testing performed on relatively undisturbed samples of the soils, presented on Figs. 3 and 4, indicate low compressibility under existing moisture conditions and light loading and generally a minor expansion potential when wetted. The samples showed moderate compressibility when loading was increased after wetting. The laboratory testing is summarized in Table I. 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, 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 soils may have variable heave or settlement potential after wetting and there could be some post - construction foundation movement if the bearing soils become wetted. Precautions should be taken to prevent wetting of the bearing soils. Footings should be a minimum width of 16 inches for continuous walls and 2 feet for columns. All topsoil, fill and loose or disturbed soils encountered at the foundation bearing level within the H-P GEOTECH Builders West LLC June 27, 2000 Page 3 excavation should be removed and the footing bearing level extended down to the undisturbed natural soils. 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 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 pcf for the on -site soil, excluding topsoil and oversized rocks, as backfill. Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support lightly loaded slab -on -grade construction. There could be some slab settlement or heave if the subgrade is 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. 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 and where clay soils are present 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 H-P GEOTECH Builders West LLC June 27, 2000 Page 4 recommend below -grade construction, such as retaining walls 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. Driveway Pavement: We understand 4 inches of Class 6 base course above 12 inches of sand, gravel and cobble subbase material is planned for the driveway section. This should be feasible for typical light traffic loading. The materials should be compacted to at least 95 % of the maximum standard Proctor density at a moisture content near optimum. 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. Drying could increase the expansion potential of the clay soils. 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. Gravel 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 H-P GEOTECH Builders West LLC June 27, 2000 Page 5 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. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Landscaping which requires regular heavy irrigation, such as sod, should be located at least 5 feet from the building. Percolation Testing: Percolation tests were conducted on Mary--=26-=2000kto evaluate the feasibility of an infiltration septic disposal system at the site. One profile pit and three percolation holes were dug at the locations 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 one day prior to testing. The soils exposed in the percolation holes are similar to those exposed in the .Rro-file=Pit-shown on Fig-2--and consist of san,dy,;silty.,clay. The percolation test results, presented in Table II, indicate average.percolation_xates of between.about 36 ;and_45-minutes per inch, The average rates were determined from the last 3 readings of each test. Based on the subsurface conditions encountered and the percolation test results, the tested area should be suitable for a conventional infiltration septic disposal system. We recomtnen&lh-einfitration area= be, -oversized due to 'the relatively s`lov�' percolation rates. 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, 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.

NOTES: 1. Exploratory pits were excavated on May 25, 2000 with a backhoe. 2. Locations of exploratory pits were approximated by pacing from features shown on the site plan provided. 3. Elevations of the exploratory pits were obtained by interpolation between contours on the site plan provided. Pit logs are drawn to depth. 4. The exploratory pit locations and elevations should be considered accurate only to the degree implied by the method used. 5. The lines between materials shown on the exploratory pit logs represent the approximate boundaries between material types and transitions may be gradual. 6. No free water was encountered in the pits at the time of excavating. Fluctuations in water level may occur with time. 7.
