Job No. 4 387 94 Dear Mr. Foster: As requested, we have conducted a preliminary geotechnical engineering study at the subject site, located along the south side of County Road 320 in Rifle, Colorado Subsoil conditions encountered in the exploratory test pits excavated in and near building areas are variable and consist of a combination of sandy clay and sandy gravel containing cobbles and boulders on Lot 2 and sand clay overlying sandstone bedrock on Lot 3. Groundwater was not encountered in the test pits at the time of our investigation. The proposed residences can be founded on spread footings placed on the natural gravel subsoils and bedrock and designed for a maximum bearing pressure of 1500 to 2000 psf, depending on the local soil conditions. A site specific subsoil study should be performed for individual structures. Moderate grading will be required to construct the driveways to access the proposed Tots. The report which follows describes our investigation, summarizes our findings, and presents our recommendations suitable for planning and preliminary design. It is important that we conduct additional subsurface investigation when building plans have been developed. We should also provide field services during construction to review and monitor the implementation of the geotechnical recommendations.

The project site is shown on Fig. 1. The purpose of the study was to provide recommendations for preliminary design of foundations and driveway subgrade. The study was conducted in accordance with our proposal for geotechnical engineering services to you, dated September 21, 1994. A field exploration program consisting of exploratory pits was conducted to obtain information on subsurface conditions. Samples obtained during the field exploration were tested in the laboratory to determine compressibility or swell and other engineering characteristics of the on -site soils. The results of the field exploration and laboratory testing were analyzed to develop preliminary recommendations for foundation types, depths and allowable pressures for the proposed residential building foundations, roadway subgrade parameters and topsoil depths. The results of the field exploration and laboratory testing are presented in the report. Evaluation of the geologic conditions which may impact construction on the site was performed based on review of existing literature and a partial site reconnaissance. This report has been prepared to summarize the data obtained during this study and to present our conclusions and recommendations based on the proposed construction and the subsoil conditions encountered. Design parameters and a discussion of geotechnical engineering considerations related to the proposed construction are included in the report. PROPOSED CONSTRUCTION The proposed development will consist of a semi- private access drive to Lots 2 and 3 and two proposed single family residential lots. The proposed building area for Lots 2 and 3 are located on the extreme north edge of each lot. The driveway from County Road 320 ascends to the south across a relatively flat area. Near the break in slope, there will be an intersection with a driveway to each building area. Cuts in the drive alignment will vary from 0 to approximately 8 feet and maximum fill depth will be on the order of 7 -8 feet. A layout of the proposed development is shown on Fig. 1. If driveway grading plans change significantly from those described above, we should Ci A member of the HUH) proop of companies Huntingdon -2- be notified to re- evaluate the recommendations contained in this report. SITE CONDITIONS Lots 2 and 3 are composed of varied terrain. The northern ends of both lots consist of gently rolling to hilly areas. To the south, the lots climb relatively steeply up to a Grass Mesa. Several minor surface drainages cross the lots from south to north and there is a larger intermittent drainage across Lot 2 along the west side of the building envelope. The sites are vegetated with pinions, junipers, sagebrush and grasses. Bedrock outcrops in several areas along the hillside. Total elevation change across the two sites is approximately 280 feet. FIELD EXPLORATION The field exploration for the project was conducted on September 23 and 26, 1994. Two exploratory pits were excavated at the locations shown on Fig. 1 to evaluate the subsurface conditions. The pits were advanced with a backhoe. The pit on Lot 3 was excavated below the actual building area because the terrain is too steep for equipment access. The pits were logged by a representative of Huntingdon. One additional pit was excavated on each lot for the purpose of percolation testing. Samples of the subsoils were taken with a 2 -inch I.D. hand drive. Bulk samples of the soils were also collected. Depths at which the samples were taken are shown on the Logs of Exploratory Pits, Fig. 2. The samples were returned to our laboratory for review by the project engineer and testing. GEOLOGY Site geology can be divided into two main areas. The northern end of Lot 2 consists of alluvial and colluvial deposits described under the "Subsurface Conditions" section of this report. �'s A member of the (HI111 group of companies • Huntingdon -3- All of the proposed development for Lot 2 and most of the driveway for Lot 3 is within these materials. The building area for Lot 2 will be underlain by colluvium /alluvium and the building area for Lot 3 will be underlain by the Wasatch Foundation. Based on a partial site reconnaissance, the only significant potential geologic hazard identified is that of rockfall. We believe the severity of the hazard is low, in part because of the tendency for the site bedrock to form slabs. Slab shaped pieces would tend to have short travel distances even on the relatively steep slopes. A positive measure for mitigation of this hazard would be to locate the residences away from the hillslope on the proposed building pads. Soil cover on the steep slopes behind the building envelope appears to be shallow, so any surficial slumping should be minor. SUBSURFACE CONDITIONS The subsoil conditions encountered at the site (shown graphically on Fig. 2) are variable with respect to their types, depths and engineering characteristics. The subsoils encountered in Pits 1 and 3, located below and in the building areas of Lot 3, generally consist of 1 foot of topsoil overlying medium dense, sandy clay. Based on the location and attitude of the outcropping bedrock it appears that excavation in the building area of Lot 3, above Test Pit 1, will encounter shallow sandstone bedrock. In Test Pit 2, located near the center of the building area of Lot 2, we encountered 0.5 feet of topsoil overlying relatively dense sandy gravel. Groundwater was not encountered at the time of excavation. The United States Soil Conservation Service classifies the site soils as the Arvada Loam. This unit is generally described as a deep, well drained silty clay loam. The Arvada Loam is shown as Map Unit 4 on the partial reproduction of Sheet 9 of 20, of the U.S. Dept. of Agriculture Soil Conservation Service, Rifle area map, dated 1977. This partial reproduction is included in the report as Figure 7. This figure indicates that the southern most ends of the lots grade into Unit 67. This unit is classified as Torriorthants -Rock Outcrop Complex, and is described generally as exposed sandstone and shale bedrock and stony soils. A member of the )H 1H) group of companies Huntingdon -4 Laboratory testing performed on samples obtained from the pits included natural moisture content, Atterberg limits testing, gradation analyses and consolidation testing. Results of consolidation testing performed on relatively undisturbed drive samples of the clay, presented on Figs. 4 and 5, indicate moderate to high compressibility under conditions of loading and wetting and high compression when wetted under constant light surcharge. Results of gradation analyses performed on a bulk sample (minus 3 -inch fraction) of the natural coarse granular soils from Lot 2, are shown on Fig. 6. Atterberg limits testing typically indicates the clay soils have moderate plasticity. The laboratory testing is summarized in Table I. PRELIMINARY DESIGN RECOMMENDATIONS Considering the subsurface conditions encountered in the exploratory pits and the general proposed construction, it appears that development of the site should be feasible based on geotechnical engineering considerations. Subsurface conditions vary considerably across the site and should be carefully evaluated for the individual lot construction when building plans are available. The following recommendations are made for planning and preliminary design purposes. When final building plans have been developed, we should be contacted for review and additional analysis as needed. FOUNDATIONS The subsoils encountered at expected foundation bearing depths on Lot 2 are mainly sandy gravels beneath a thin veneer of sandy clay. Although Test Pit 3 did not penetrate the sandy clay, we anticipate that the strata at foundation bearing levels will consist of the sandstone bedrock exposed lower in the slope on Lot 3. The natural granular soils on Lot 2 and bedrock on Lot 3 should be suitable for support of lightly loaded spread footings. Footings can probably be sized to impose a maximum bearing pressure of 1500 psf to 2000 psf, depending on the local soil conditions. The upper clay soils are compressible and could result in some post- construction foundation settlement if the structures bear on them. �'3 A member of the [H I HJ group of companies Huntingdon -5- Settlement potential of foundations should be evaluated as part of the site specific foundation study for the individual structures. FLOOR SLABS The natural on -site granular soils and bedrock should support lightly loaded slab -on -grade construction, typical of residential construction. The on -site clay soils are compressible in their native state but should be suitable for use as underslab fill, if properly compacted. To reduce the effects of some differential movement, floor slabs should be constructed independent from the building foundation. UNDERDRAIN SYSTEM Individual buildings should have foundation drains to prevent wetting of the below grade areas and prevent hydrostatic pressure buildup behind foundation walls and retaining structures. The foundation drains should consist of drainpipe surrounded by free - draining granular material placed at least 1 foot below the bottom of the proposed excavation. The free - draining gravel backfill should be surrounded by a suitable filter fabric to reduce infiltration of the on -site fine - grained soil into the gravel. The drain line should be sloped at a minimum 1% grade and connected to a gravity outlet pipe. Free - draining granular material used in the drain systems 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. DRIVEWAY CONSTRUCTION The subsoils encountered within the proposed roadway alignment were evaluated using standard property tests to estimate an 'R' value. The test results are summarized in Table I. Clayey fine - grained soils, such as those encountered at the site, typically have poor load support properties. The soils in this area are also known to be frost susceptible. Based on the other tests results and our experience in the area, we recommend an 'R' value of 15 be used for design of pavement sections on the sandy clay subgrade. a A member or the ® group of companies • Huntingdon -6- Subgrade soils should be scarified, adjusted to near optimum moisture and compacted to 95 % of the standard Proctor density prior to placement of base course or surfacing materials. A preliminary roadway section consisting of a layer of "pit -run" material over properly prepared subgrade and surfaced with a 4 -inch aggregate base layer should be suitable for typical residential traffic. Heavy construction traffic could damage the roadways and placement of additional base and regrading may be necessary in a post- construction phase. In some areas overexcavation and placement of compacted granular borrow or additional aggregate base course may be necessary to stabilize the driveway section. PERCOLATION TESTING Preliminary percolation testing was performed in the proposed leach field areas of the building sites. The subsoil profiles were logged in the adjacent exploratory test pits. No free water was observed in the exploratory or percolation pits. The testing was performed in hand dug holes in the bottom of the backhoe excavated pits. The results of the percolation testing are presented in Table II. The results indicate the subsoils have a variable percolation rate but should be acceptable for conventional infiltration septic disposal systems. SITE GRADING Drainage ditches should be provided along the uphill side of the driveways to divert surface water away from the road section. The proposed site grading will consist of minor cut and fill to allow construction of' the semi - private driveways and building sites. We assume proposed cut depths will not exceed about 10 feet and maximum fill depths will be about 5 to 7 feet. The following criteria can be used in developing preliminary grading plans. Grading of the property should limit cut and fill depths as much as possible. Permanent unretained cut and fill slopes which do not encounter seepage should be graded at 2 horizontal to 1 vertical or flatter. If groundwater seepage is encountered or where deeper cuts are proposed, we recommend that they be evaluated for stability on an individual basis. Interceptor drains will be needed above the building pads to divert surface flow around the building areas. We do not anticipate unusual problems with the proposed fill slopes provided the fills are A member of the (HI I{J oipip of tornpanies Huntingdon • -7 properly compacted and the slopes do not exceed 2 horizontal to 1 vertical. We understand that the larger intermittent drainage crossing Lot 2 will be re- channeled, to the west away from the proposed building area. We recommend that the east side of the new channel be protected from erosion from the mouth of the drainage along the length of the building area for Lot 2. This could be done by the placement of rip -rap or channel lining. On -site sandstone cobbles and boulders should be suitable for rip -rap. A typical channel section is shown on Fig. 8. Areas to receive fill should be carefully prepared prior to fill placement by removing all vegetation, topsoil and other deleterious materials. The exposed subgrade should be scarified and compacted to provide a uniform base for fill placement. Fills placed on hillsides exceeding 2 horizontal to 1 vertical should be benched into the hillsides. Fill material should be compacted to at least 95% of standard Proctor density at a moisture content near optimum in areas to be developed and 90% in landscape areas. Fill sections deeper than 10 feet should be studied on an individual basis for slope stability and settlement potential. c7 A member or ft (HIM group of companies Huntingdon -8 ADDITIONAL STUDIES This report has been prepared in accordance with generally accepted geotechnical engineering practices in the area and is suitable for planning and preliminary design purposes.
