The bearing capacity can be increased by one third for transient loading conditions such as earthquake and wind. Additional parameters for shallow foundations are provided below. Minimum Footing Width: 18 inches for continuous footings 24 inches for square/rectangular footings Minimum Footing Depth: 18 inches below lowest adjacent soil grade Minimum Reinforcement: Two No. 5 bars at both top and bottom in continuous footings. • Canopy Foundations: Typical shallow drilled pier footings for the canopy columns are expected to provide adequate support for the proposed structures provided that the recommendations provided herein are incorporated in the design. We understand that typical canopy column footings will consist of reinforced concrete drilled piers having a minimum diameter or width of 4 feet and embedded a minimum depth of 7 feet bgs. Based on these assumptions and the anticipated subsurface conditions, an allowable bearing pressure of 4,000 psf may be used in the design. For resistance to transient lateral loads, such as earthquake and wind loads, the aforementioned allowable bearing capacity may be increased by one-third. • Lateral Resistance: Lateral loads will be resisted by friction between the bottoms of footings and passive pressure on the faces of footings and other structural elements below grade. An allowable coefficient of friction of 0.30 can be Review and approval of construction plans Prior to grading permits City of Santa Ana 1-22
