A. Not Expansion of Nonconforming Use: Towers that are constructed, and antennas that are installed, in accordance with the provisions of this chapter shall not be deemed to constitute the expansion of a nonconforming use or structure.

B. Pre-existing towers: Pre-existing towers shall be allowed to continue their usage as they presently exist. Routine maintenance (including replacement with a new tower of like construction and height) shall be permitted on such preexisting towers. New construction other than routine maintenance on a preexisting tower shall comply with the requirements of this chapter.

C. Rebuilding Damaged or Destroyed Nonconforming Towers or Antennas: Notwithstanding other provisions of this chapter, bona fide nonconforming towers or antennas that are damaged or destroyed may be rebuilt without having to first obtain a special use permit and without having to meet the separation requirements specified in Sections 17.07(A) and 17.07(B). The type, height, and location of the tower onsite shall be of the same type and intensity as the original facility approval; provided, however, that any destroyed lattice or guyed tower shall be replaced with a monopole structure only. Building permits to rebuild the facility shall comply with the then applicable building codes and shall be obtained within ninety (90) days from the date the facility is damaged or destroyed. If no permit is obtained or if said permit expires, the tower or antenna shall be deemed abandoned as specified in Section 17.10.
