Property Address: 7901 Santa Clara Blvd., St. Lucie, Florida 34951 Re: HIGH WIND -RESISTANT CONSTRUCTION CERTIFICATE SCANNED StLucie County Wind loads have been calculated for a speed of 157 MPH. The roof pitch and construction have been analyzed, and the photovoltaic system structure designed to resist resulting uplift and downward forces. The attached drawings and diagrams reflect a design that safely transmits dead and live loads to the roof. To the best of my professional knowledge and belief, the subject construction and photovoltaic system installation will be in compliance and designed to 2017 Florida Building Code 6th Edition at the time of our review. i '0 ST.LUCIE COUNTY REVIEW, PLAN BLDG: ELEC:_-__ DATE` PLUMB: DATE;,�,,.�_.
