These plans were reviewed for conformance with the <br />assumptions, conclusions, and recommendations of the above referenced report. The foundation plans <br />for the proposed development were prepared by Superior Electrical Advertising, Inc. and YJ, Inc. and <br />are identified as follows: <br />Page 02.1, dated May 3, 2016. <br />Page 14, dated May 3, 2016. <br />Page 14.1, dated May 3, 2016, Calculations by YJ, Inc <br />Page 15, dated May 3, 2016. <br />In addition, we contacted Mr. Yousif Jacob of YJ, inc. to discuss the proposed drilled pier <br />One comment was generated during our review of these plans and as a result of our communications <br />with Yl, Inc.: <br />The plans indicate that YJ, Inc. has designed a single 6-foot-diameter drilled pier that is 25, 3,, <br />below proposed finish grade. This drilled pier is larger than the 36-inch-diameter drilled pier and <br />shorter than the 42-foot-long drilled pier analyzed in the above-referenced report. Therefore, we <br />performed deep foundation analysis on the proposed 6-foot-diameter, 25'3'rlong drilled pier <br />based on the following design loads and settlemenvdeflection tolerances provided to me by yl, <br />Inc.: <br />. Design axial load at the top of the drilled pier (-ground surface): 9,000 lb. Design moment at the top of the drilled pier (-ground surface): 925,000 ft-lb. Design lateral load at the top of the drilled pier (-ground surface): 23,000 lb. l'laximum allowable lateral deflection at the top of the drilled pier: 3/a inch. Maximum allowable vertical settlement for the drilled pier: y2 inch <br />22885 Savi Ranch Parkway - <br />voice: (714) 685-1115 - <br />Suite E - Yorba Linda - Glifornia - 92887 <br />tax: (7l4)685-1118 - www.lqeo.com <br />Gentlemen: <br />SoCalceo
