It is our opinion the footing sizes shown on the foundation plan dated February 8, 2008 are adequate for the design loads. We do recommend adding #4 vertical and horizontal rebar spaced at 36" on center to the foundation walls provided each side of the foundation wall is backfilled concurrently to about the same height.

The location of the subject sites are presented on Figures 1 and 2. The purpose of the study was to develop recommendations for design and construction of single-family residences on the subject lots. The field investigation consisted of drilling one exploratory test hole on each lot within close proximity to the building envelopes. Due to heavy snow cover at the time of this investigation, the lots required a plowed path for drill rig access. The paths were plowed by a representative of the client and the test holes were drilled at a point where the path clearing -terminated. Samples of the subsurface materials were collected and returned to our laboratory for testing. The results of our field and laboratory programs were evaluated to develop recommendations for building foundations and surface and subsurface drainage. This report summarizes the information obtained during our investigation and presents our recommendations based on the proposed construction and subsurface conditions encountered. PREVIOUS INVESTIGATIONS Yeh and Associates has conducted a previous investigation for Lots 20, 27, 28, 42 and 48 in Pinyon Mesa Subdivision under our Project No. 27-362, dated January 15, 2008. Our previous investigation was reviewed prior to completion of this report. PROPOSED CONSTRUCTION The proposed residences will be one to two-story wood framed structures with or without basements. For non-basement structures, foundation excavations will likely be on the order of 3 to 4 feet deep. For basement structures, foundation excavations will likely be on the order of 8 to 10 feet deep. We anticipate the main level floor will be structurally supported. Foundation loads will likely be on the order of 1,000 to 3,000 pounds per linear foot. The lots included in this investigation are presented on Figure 2. SITE CONDITIONS Pinyon Mesa is located south of Glenwood Springs, Colorado and more particular, about one mile up and on the south side of County Road 114 from the intersection of Highway 82. The subject lots were vacant within a developed subdivision. Vacant lots were located around the subject lots. Lots 21 and 29 were situated on the eastern half of the subdivision. Streets were paved and utilities have been installed. The site sloped down to the west at grades of 1 Lots 21 and 29 Pinyon Mesa Project No. 27 ~362A about 4 to 13 percent. The building envelope on Lot 21 was partially cleared of scrub and the entire site was covered with snow at the time of this investigation. SUBSURFACE CONDITIONS An exploratory test hole was drilled within close proximity to the building envelope on each lot. The test holes were drilled to a depth of 25 feet. Modified California samples were collected at specified depths. California samples were collected using a 2-inch I.D. sampler driven into the subsoils with a 140-pound hammer falling 30 inches. The number of blows needed to drive the sampler constitutes the blow count. For example, a value on the log (Figure 3) of 16/12 indicates the sampler was driven 12 inches with 16 blows of the hammer. The blow count can be used as a relatively measure of material stiffness or density. The collected samples were transported to our laboratory where they were examined and classified. Laboratory tests included moisture content, dry density, swell/consolidation, grain size analysis and Atterberg limit testing. Generally, the subsoils encountered in our test holes consisted of sandy clay with interlayered silt. Bedrock was not encountered to the maximum depth explored. The clay samples tested had 60 to 77 percent fines (passing No. 200 sieve). One clay sample tested had a liquid limit of 28 percent and a plastic index of 9 percent. One clay sample exhibited low swell (0.2 percent) and one clay sample exhibited moderate consolidation (-3.5 percent) when wetted under an applied pressure of 1,000 psf. The laboratory test results are presented on Figure 4 and are summarized in the Summary of Laboratory Test Results table. Groundwater was not encountered during drilling, and the subsoils were slightly moist to moist. We believe variations in ground water conditions can occur. The magnitude of the variation will be largely dependent upon local irrigation practices, the duration and intensity of precipitation, site grading changes, and the surface and subsurface drainage characteristics of the surrounding area. SITE DEVELOPMENT We understand cuts of about 3 to 4 feet from existing grade may be necessary to reach foundation level for crawlspace construction and 8 to 10 feet from existing grade for basement construction. Fill placement should be minor. Areas to receive fill should be stripped of vegetation, organic soils and debris. The on-site soils free of organic matter, debris and rocks larger than 6 inches can be used in fills. Fill should be placed in thin, loose lifts of 8 inches thick 2 Lots 21 and 29 Pinyon Mesa Project No. 27 -362A or less, moisture conditioned to 0 to 3 percent above optimum moisture content and compacted to at least 95 percent of maximum standard Proctor dry density (ASTM D 698). Placement and compaction of fill should be observed and tested by a geotechnical engineer. FOUNDATIONS RECOMMENDATIONS Based on the results of our previous and this subsurface investigations, we judge these lots as low collapsible risk overall and therefore believe the residences can be supported on footing foundations placed on the natural soils or properly compacted fill. Based on our experience and laboratory test results, we believe there is a low risk of consolidation and therefore a low risk of foundation movement provided the following recommendations are followed. The following design and construction details should be observed for spread footings placed on the natural soils or properly compacted fill. 1. Foundations should be constructed on undisturbed, natural soils. Loose, disturbed soils encountered at foundation level should be removed and replaced with compacted fill or the foundation should be extended to undisturbed soils. 2. Footing foundations can be designed for a maximum allowable soil pressure of 2,000 psf. The design pressure may be increased by 1/3 or as allowed by local code, when considering total loads that include wind or seismic conditions. 3. Continuous wall footings should have a minimum width of at least 18 inches. Foundation pads for isolated columns should have a minimum dimension of 24 inches. 4. Resistance to sliding at the bottom of the footing can be calculated based on a coefficient of friction of 0.30. Passive pressure against the side of the footing can also be considered for the sliding resistance if it is properly compacted. Passive pressure can be estimated based on an equivalent fluid density of 300 pcf for a level backfill. 5. Grade beams and foundation walls should be reinforced to span undisclosed loose or soft soil areas. We recommend reinforcement sufficient to span an unsupported distance of at least 10 feet. 6. The soils below exterior footings or exterior edges of slabs should be protected from freezing. We recommend the bottom of footings be constructed at least 3 feet below finished exterior grade or as required by local municipal code. 7. All foundation excavations should be observed by a representative of the geotechnical engineer prior to placement of concrete. 3 Lots 21 and 29 Pinyon Mesa BELOW-GRADE WALLS Project No. 27 -362A Crawlspaces or basements are planned below the main level for these residences. Foundation walls that extend below grade should be designed for lateral earth pressure where backfill is not present to the same level on both sides of the wall. For walls that can deflect or rotate about 0.5 to 1 percent of the wall height, the wall can be designed for "active" earth pressure conditions. For a very rigid wall where negligible deflection can occur, an "at-rest" lateral earth pressure condition can be used. Typically, below-grade walls for residences can rotate under normal design loads, and this deflection results in acceptable performance. If on-site soils are used as backfill, we recommend using an equivalent fluid density of 45 pcf for design of below grade walls. This value assumes that some minor cracking is acceptable. If negligible deflections are desired, a higher equivalent fluid density of 60 pcf should be used for design. These equivalent densities do not account for sloping backfill, surcharges or hydrostatic pressure. SLABS-ON-GRADE Based on our investigation, garage and driveway slabs will likely be underlain by clay with interlayered silt soils. We believe there is a low risk of poor slab-on-grade performance due to collapsible soils. The on-site soils, free of organics and debris, are suitable to support lightly loaded slabs-on-grade. Slabs should be separated from all load bearing walls and columns with expansion joints that allow vertical movement. Control joints should be used to reduce damage from shrinkage cracking. All fill below slabs should be compacted to at least 95 percent of maximum standard Proctor dry density within 2 percent of optimum moisture content. SUBSURFACE DRAINAGE Groundwater was not encountered during our investigation. Surface water typically flows through permeable wall backfill and collects at the backfill and natural soil interface resulting in saturated foundation soils and/or wet crawlspace conditions. To reduce water accumulation outside foundation walls and reduce moist crawlspace and basement conditions, a foundation drain could be installed around the exterior of the foundation walls. Drains could be installed in crawlspace areas after completion of construction, if groundwater develops. If groundwater or highly saturated soils are encountered during foundation excavation on these lots, we should be contacted for additional recommendations. A typical drain should consist of a 4-inch diameter, perforated pipe encased in free draining gravel. The gravel should be% to 1.5-inch washed rock with less than 5 percent fines. 4 Lots 21 and 29 Pinyon Mesa Project No. 27 w362A The drain should be provided with a gravity discharge such as a sump pit where water can be removed by pumping or be daylighted. The pipe should be sloped at a minimum of 1 percent and should be installed 12 to 18 inches away from and parallel to the footing foundation. The bottom of the pipe should be at least 2 inches below the bottom of footing level at the high point. Crawlspace areas should also be provided with adequate ventilation. SURFACE DRAINAGE Surface drainage is crucial to the performance of foundations and flatwork. We recommend the ground surface surrounding the building be sloped to drain away from the structure. We recommend a slope of at least 6 inches in the first 10 feet for landscape areas and a minimum slope of 1 percent for paved areas. Backfill around foundations should be moisture conditioned and compacted as recommended in the SITE DEVELOPMENT section. Roof downspouts and drains should discharge beyond the backfill area. WATER SOLUBLE SULFATE Based on the results of water-soluble sulfate concentrations that were measured, we anticipate a Class 2 exposure for concrete due to the presence of water-soluble sulfate. Based on ACI 201.2R-01, "Guide to Durable Concrete," concentrations between 0.2 and 2.0 percent represent Class 2 exposure (severe). For cast-in-place structures, ACI recommends equivalent Type V cement or any blend of cement meeting ASTM C 150 or C 1157. For cast-in-place structures in contact with structural fill, any type of concrete may be used. Structural fill is assumed to have Class 0 or no effect on concrete. LIMITATIONS The analyses and recommendations presented in this report are based upon our data obtained from the borings at the indicated locations, field observations, laboratory testing, our understanding of the proposed construction and other information discussed in this report. It is possible that subsurface conditions may vary between or beyond the points explored. The nature and extent of such variations may not become evident until construction. If variations appear, we should be contacted immediately so we can review our report in light of the variations and provide supplemental recommendations as necessary.
