GEOTECHNICAL ENGINEERING STUDY McDonald's Corporation E-6893-1 June 9, 1995 Page 3 Groundwater Groundwater seepage was not observed in any of the test pits during the time our site study was performed. It is important to note that groundwater seepage is not constant; thus, one may Expect fluctuations in the volume and location depending on the season, amount of rainfall, surface water runoff, and other factors. Generally, groundwater seepage is greater during the wetter winter months (typically October through May). Groundwater seepage is not expected to have a significant impact on construction unless the site is developed during periods of heavy precipitation or the winter months. Laboratory Testing Laboratory tests were conducted on representative soil samples to verify or modify the field soil classification of the units encountered and to evaluate the general physical properties and engineering characteristics of the soils encountered. Visual classifications were supplemented by index tests, such as sieve analysis, and by moisture content tests on representative samples. The results of laboratory tests performed on specific samples are provided either at the appropriate sample depth on the individual test pit log or on a separate data sheet contained in Appendix B. However, 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. The soil samples for this project will be discarded after a period of fifteen (15) 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 that the site can be developed generally as planned provided the recommendations contained in this report are incorporated into the final design. In our opinion, the proposed restaurant may be supported on spread footings bearing on the dense native soil or on structural fill, depending on design grades. These and other geotechnically related aspects of the project are discussed in the following sections of this report. Earth Conauhmta, Inc.
