(A) All signs, except those attached flat against the wall of a building shall be constructed to withstand wind loads as follows:
(1) For solid signs, 30 pounds per square foot on one face of the sign.
(2) For skeleton signs, 36 pounds per square foot of the total face area of the letters and other sign surfaces, or ten pounds per square foot of the gross area of the sign as determined by the overall dimensions of the sign, whichever is greater.
(B) The wind loadings quoted above are normal averages and must be adjusted for areas subject to unusually high velocity winds, for signs of extraordinary height or for certain wind tunneling effects created by large buildings.
