City of Santa Ana <br />7-Eleven Convenience Store and Service Station Project <br />Mitigation Monitoring and Reporting Program <br />Table 1 (cont.): 7-Eleven Convenience Store and Service Station Project Mitigation Monitoring and Reporting Program <br />Mitigation Measures <br />Method of Verification <br />MM GEO-2: Conventional Shallow Foundations Review and approval of <br />An allowable bearing pressure of 2,500 psf shall be used for construction plans <br />conventional square or rectangular shallow foundations <br />founded in properly compacted fill. The bearing capacity can <br />be increased by one third for transient loading conditions such <br />as earthquake and wind. <br />Additional parameters for shallow foundations are provided <br />below. <br />Minimum Footing Width: 18 inches for continuous footings 24 <br />inches for square/rectangular footings <br />Minimum Footing Depth: 18 inches below lowest adjacent soil <br />grade <br />Minimum Reinforcement: Two No. 5 bars at both top and <br />bottom in continuous footings. <br />Canopy Foundations: Typical shallow drilled pier footings for <br />the canopy columns are expected to provide adequate <br />support for the proposed structures provided that the <br />recommendations provided herein are incorporated in the <br />design. We understand that typical canopy column footings <br />will consist of reinforced concrete drilled piers having a <br />minimum diameter or width of 4 feet and embedded a <br />minimum depth of 7 feet bgs. Based on these assumptions <br />and the anticipated subsurface conditions, an allowable <br />bearing pressure of 4,000 psf may be used in the design. For <br />resistance to transient lateral loads, such as earthquake and <br />wind loads, the aforementioned allowable bearing capacity <br />may be increased by one-third. <br />Lateral Resistance: Lateral loads will be resisted by friction <br />between the bottoms of footings and passive pressure on <br />the faces of footings and other structural elements below <br />grade. An allowable coefficient of friction of 0.30 can be <br />FirstCarbon Solutions <br />Y:\Publications\Client(PN-1N)\0327\03270041\MMRP\03270041 City of Santa Ana 7-Eleven MMRP.docx <br />Verification of Completion <br />Responsible for <br />Timing of Verification Verification Date Initial <br />Prior to grading City of Santa Ana <br />permits <br />1-22 <br />
