The use of the <br />seismic coefficients herein above are intended to prevent loss of life and to minimize but <br />not entirely eliminate structural damage. <br />Moreover, major foundation problems are not anticipated as a result of <br />earthquake-induced liquefaction, fault ground rupture or displacement and settlement <br />provided the proposed foundation system is constructed as recommended with the <br />limitations mentioned here. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />1022 S Hickory St <br />1/9/2025
