Lot 11. Teller Sprlnis. Garfield County. Colorado Dear Mr. Deer: 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 June 25, 2001. 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 and barn/ADU will be one story wood frame structureS located on the site as shown on Fig. 1. Ground floors are proposed to be slab-on-grade. CUt depths are expected to range between about 3 to 6 feet. For the pwpose of our anslysis, foundation loadings are assumed to be relatively light and typical of the proposed type of construction. The septic disposal system is proposed to be located to the south of the barn/ADU building. If building conditions or foundation loadings are significantly different from those described above, we should be notified to re-evaluate the recoonnendations presented in this report. Site Conditions: The lot is funner pasture land located on the east side of County Road Hl9. The ground surface in the building areas is relatively flat with a gentle slope down to the northeast. There is about 7 and 3 feet of elevation difference across the residence and barn/ ADU footprints, respectively. An irrigation ditch is located to the east of the proposed buildings. The lot is vegetated with grass and weeds. ... .. ,· Mike Deer July 6, 2001 Page2 Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating four exploratory pits in the building areas and one profile pit in the septic disposal area at the approximate lucatiuns shown on Fig. 1. The logs of the pits are presented on Fig. 2. The subsoils encountered, below up to about 2 feet of topsoil, consist of relatively stiff, slightly sandy silty clay. Very sandy clay with scattered gravel below one foot of topsoil was encountered at Pit 4. Results of swell-'> • consolidation testing performed on relatively undisturbed samples of slightly sandy silty clay, presented on Figs. 3 and 4, indicate low compressibility under existing moisture conditions and light loading and a low collapse potential (settlement under a constant load) when wetted. The samples showed moderate to high compressibility under increased loading after wetting. Atterberg limits testing indicates the clay soils have low compressibility. 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. Subsidence Potential: Bedrock of the Pennsylvanian age Eagle Valley Evaporite underlies Teller Springs. These: rucb are a sequence of gypslferous shale, ftne..gralned sandstone/siltstone and limestone with some massive beds of gypswn. There is a possibility that massive gypsum deposits associated with the Eagle Valley Evaporite underlie portioos of the lot. Dissolution of the gypsum under certain conditions can cause sinkholes to develop and can produce area of localized subsidence. During previous work In the area, a few sinkholes were observed in the terraces close to the Roaring Fork River at Teller Springs. These sinkholes appear similar to others associated with the Eagle Valley Evaporite in areas of the Roaring Fork Valley. Sinkholes were not observed in the immediate area of the subject lot. No evidence of cavities was encountered in the subsurface materials; however, the exploratory pits were relatively shallow, for foundation design only. Based on our present knowledge of the subsurface conditions at the site, it cannot be said for certain that sinkholes will not develop. The risk of future ground subsidence on Lot 11 throughout the service life of the proposed resideucc, in our opinion, ib luw; however, the owner should be made aware of the potential for sinkhole development. If further investigation of possible H·P GEOTCCH • r • I Mike Deer July 6, 2001 Page3 cavities in the bedrock below the site Is desired, we should be contacted. Foundation Reoommemlatiullli: 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 subsoils designed for an allowable soil bearing pressure of 1,200 psf for support of the proposed buildings. The soils tend to compress after wetting and there could be some post-construction foundauon settlement. Footings should be a minimum width of 18 inches for continuous walls and 2 feet for columns. l..oose 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 firm natural soils. Exterior footings should be provided with adequate cover above their bearing elevations for frost protection. Placement of footingR at least 36 inches below the exterior grade is typically used in this area. Continuous foundation walls should be reinforced top 8Dd bottom to span local anomalies such as by assuming an nnsupported length of at least 12 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 SS pcf fur 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. 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 verticld 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. :bis material should consist of minus 2 inch aggregate with less than SO% 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 dew;ity at a moiMure conr.ent near optimum. Required fill can consist of the on-site soils devoid of vegetation, topsoil and oversized rock.

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. 4) Roof downspouls an<l drains should discharge well beyond the limits of all backfill. 5) I .andscaping which requires regular heavy irrigation should be located at least 10 feet from the building. Consideration should be given to the uac of xeriscape to limit potential wetting due to irrigation. Percoladon TestJq: Percolation tests were conducted on June 28, 2001 to evaluate the feasibility of an infiltration septic disposal system at the proposed location on the property. One profile pit and three percolation holes were dug at the locations shown on Fie. 1. The test holes (oominal 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 boles are similar to those exposed in the Profile Pit shown on Fig. 2 and consist of relatively stiff, slightly sandy silty clay. Percolation test results indicate infiltration rates between 30 and 120 minutes per inch with an average rate of 90 minutes per inch. 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 H-P GFOTfCH .· ,. Mike Deer July 6, 2()()1 Pages in this report are based upon the data obtained from the exploratory pits excavated at the locations indicated on Fig. l, the proposed type of construction, percolation test results 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 0 i the recom:nendations 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 recolllOlendations 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 geotecbnical engineer.
