As I recall wind pressure "on a flat surface" at 70 mph is 20.6 lbs/sq ft., so if the tower is rated for 18 sq ft at 70 mph, would it be too much of a stretch to say to the zoning board that since wind pressure at 90 mph is 34 lbs/sq ft, by simple math, the tower should be good for 10.9 sq ft at 90 mph ?
