' Based upon our. review of ffie 2 Photovoltaic Arrays, installed 4. modules high and 5 modules wide. The PV Array shall have a transverse spacing of approximately 5..58 feet on center and, a longitudinal spacing of 7.58 feet maximum. Based upon.a wind speed of 100 mph, Exposure C, it was determined that the minimum required footing depth; is 30 inches minimum below grade for the front footing and 36 inches minimum below grade for the rear:footing for a 12 inch diameter pier footing. The footing sizes are ' based upon:the worst case loading -due to horizontal and vertical wind loading. Refer to attached calculations and details:for additional. information.
