6.0 coNcLUstoNS <br />Based on the results of our subsurface investigation, it is our opinion that the proposed <br />residential development is feasible from a geotechnical standpoint, provided the <br />recommendations contained herein are incorporated in the design and construction. The <br />following is a summary of the geotechnical design and construction factors that may affect <br />development of the site. <br />6.1 Seismicity <br />Based on our studies on seismicity, there are no known active faults crossing the property. <br />However, the site is located in a seismically active region and is subject to seismically induced <br />ground shaking from nearby and distant faults, which is a characteristic of all Southern <br />California areas. <br />6.2 Liquefaction <br />We recommend the proposed new structure be designed based on upto-date building codes <br />and be supported by a strengthened foundation system as recommended in this report to <br />reduce the potential adverse effects due to the potential liquefaction to the proposed new <br />structure. <br />6.3 Groundwater <br />Ground water was not encountered at a depth of about 5 feet below the existing ground <br />surface during our subsurface investigation. ln our opinion, groundwaler will not be a <br />problem during the near surface construction. <br />6.4 Expansion Potential <br />Based on our field observation and testing of sample of the near ground surface on-site earth <br />materials, the foundation subgrade soils at the site generally consisted of silty very fine sand <br />and have a very low expansion potential. <br />Page 7
