1171.07 NONCONFORMING SIGNS.
   (a)   Abandonment. The continuance of an existing sign which does not meet the regulations and requirements of this chapter shall be deemed a nonconforming sign which shall terminate by abandonment when any of the following conditions exist:
      (1)   When the sign is associated with an abandoned use.
      (2)   When the sign remains after the termination of a business. A business has ceased operations if it is closed to the public for at least ninety (90) consecutive days. Seasonal businesses are exempt from this requirement.
      (3)   When the sign is not maintained or does not conform to the following:
         A.   All signs, together with all supports, braces, guys and anchors shall be kept in a proper state of repair.
         B.   Every sign and the immediately surrounding premises shall be maintained by the owner, or his agent, in a clean sanitary and inoffensive condition, free from all obnoxious substances, rubbish and weeds.
   Upon finding that the sign is abandoned, the right to maintain and use such sign shall terminate immediately.
   (b)   Relocation or Replacement. A nonconforming sign shall not be structurally relocated or replaced unless it is brought into compliance with the provisions of this Section. Should any replacement or relocation occur without being brought into compliance, the sign shall be existing illegally, and subject to the penalties as specified in Section 1171.08 of this Ordinance.
   (c)   Maintenance. A nonconforming sign shall be maintained or repaired in accordance with the following provisions:
      (1)   The size and structural shape of the sign shall not be changed or altered. The copy may be changed provided that the change applies to the original use associated with the sign at the time the sign became nonconforming. The copy area shall not be enlarged.
      (2)   In case damage occurs to the sign to the extent that more than 50 percent (50%) of the replacement value is lost, the sign shall be removed within sixty (60) days.
