Box 9231 Chico, CA 95927 Subject: Review of minimum footing requirements Project: (168) Module Photovoltaic Groundmount Installation (1 Array) Burch Creek - County Line Highway 99 E, Chico, CA 95973 V&A Project No. 12-3457 The purpose of this report is to provide a site specific analysis of the minimum footing requirements for the photovoltaic array groundtrac installation at Highway 99 E in Chico, CA 95973. Based upon our review of the 1 Photovoltaic Array, installed 4 modules high and 42 modules wide. The PV Array shall have a transverse spacing of approximately 8.42 feet on center and a longitudinal spacing of 8.00 feet maximum. Based upon a wind speed of 100 mph, Exposure C, it was determined that the Krinner KSF PV M24/PV T 76x1600 ground screw is sufficient for the applicable horizontal and vertical wind loading. Refer to attached calculations and details for additional information. Our professional services have been performed using the degree of care and skill ordinarily L exercised under similar circumstances by reputable engineers practicing in this locality. No other warranty, expressed or i ied, is made as to the professional options included in this report. We hope this prov' es ou with the information you need at this time.
