Any existing communication tower or antenna which becomes nonconforming on the effective date hereof or becomes nonconforming at any future date shall be regulated according to the rules set forth in chapter 4 of this title, except as follows:
A. New antennas and support facilities may be mounted on a nonconforming communication tower.
B. A nonconforming communication tower within one thousand feet (1,000') of a historic preservation district shall be considered a legal nonconforming tower. As such, the tower may remain until it has been abandoned.
C. Should any lawful nonconforming communication tower be destroyed by any means to an extent of more than seventy five percent (75%) of its replacement cost at the time of destruction, it may only be reconstructed in conformance with the provisions of this section 16-7-2, provided that the destruction was caused by an accident or act of God occurring after the adoption of this section 16-7-2 and such reconstruction does not increase the degree of nonconformity that existed prior to destruction.
