Intracorp E-3592-520 _ September 23, 1998 Page 3 Groundwater Groundwater seepage was not observed at any of our test pit locations, but the observed soils typically became moist to wet at approximately nine feet below existing grade. Based on proposed finished grades and upon observed site conditions we do not anticipate groundwater seepage will be encountered in site excavations. However, the contractor should be aware that groundwater levels are not static. Groundwater levels can be expected to fluctuate significantly depending on the season, amount of rainfall, surface water runoff, and other factors. Generally, the groundwater level is higher in the wetter winter months (typically October through May). The contractor should be prepared to control groundwater if seepage is encountered in site excavations Laboratory Testina Laboratory tests were conducted on several representative soil samples to verify or modify the field soil classification and to evaluate the general physical properties and engineering characteristics of the soil encountered. Visual classifications were supplemented by grains size analyses on representative samples. Moisture content tests were performed on all samples. The results of laboratory tests performed on specific samples are provided either at the appropriate sample depth on the individual test pit logs or on a separate data sheet contained in Appendix B. It is important to note that these test results may not accurately represent the overall in-situ soil conditions. Our geotechnical recommendations are based on our interpretation of these test results and their use in guiding our engineeringjudgement. ECI cannot be responsible for the interpretation of these data by others. In accordance with our Standard Fee Schedule and General Conditions, the soil samples for this project will be discarded after a period of fifteen days following completion of this report, unless we are otherwise directed in writing. DISCUSSION AND RECOMMENDATIONS General Based on the results of our study, it is our opinion the proposed building can be constructed generally as planned. Building support can be provided using a conventional spread and continuous footing foundation bearing on competent native soil, or on structural fill used to modify site grades. Slab-on-grade floors may be similarly supported. As part of our study, we conducted a reconnaissance of the north, east and southeast slopes. Based on the results of our reconnaissance, it is our opinion the site slopes are stable and should not be adversely impacted by the proposed development provided the recommendations in this letter are followed.
