[Ord. No. 646 §2]
The restoration of any structure and its use, when such structure has been damaged by fire, explosion, act of God or the public enemy to an extent less than sixty percent of its replacement value at the time of destruction, may be permitted, provided the restoration of such structure and its use in no way increases any former nonconformity; and provided, further, that restoration of such structure is begun within six months of such damage an diligently prosecuted to completion within two years following such damage. Where damage to the structure is more than sixty percent of the replacement value at the time of damage, the structure shall not be restored except in full conformity with all the regulations of the district in which such structure is situated. However, none of the restrictions contained in this section shall limit the authority of the board of adjustment to grant relief for reconstruction of a nonconforming use if it finds some compelling public necessity requiring the continuance of the nonconforming use and the primary purpose of continuing the nonconforming use is not to continue a monopoly.
