(A) All signs which have been installed, and were lawful at the time of installation, and are in existence as of the effective date of this chapter, which do not conform to this chapter shall be known as "preexisting non-conforming signs." Such preexisting non-conforming signs need not comply with the provisions of this chapter except as follows:
(1) Any changes to a preexisting non-conforming sign, other than routine repair or maintenance, require that said sign be brought into compliance with all applicable city ordinances.
(2) When a preexisting non-conforming sign becomes an abandoned sign, its status as a preexisting non-conforming sign shall terminate.
(B) The lighting of a preexisting non-conforming illuminated sign shall be brought into conformity with this chapter.
(C) Removal of destroyed signs. A preexisting non-conforming sign shall be considered destroyed if the cost of repairing the sign, after a part of it has been destroyed or dismantled, is more than 60% of the cost of erecting a new sign of the same type at the same location. A destroyed sign must be removed by the responsible party without compensation by the city and within 30 days of the damage, destruction or dismantling. A preexisting non-conforming sign that has been destroyed may not be replaced or rebuilt except by a sign which is in full conformity with this subchapter.
