Replacement. If any nonconforming structure is hereafter damaged or destroyed, in whole or in part, such nonconforming structure may be replaced on its identical footprint, subject to site plan approval from the Planning Board pursuant to Article XI of this chapter, which approval must be sought within one year of the damage or destruction, provided that the structure is not added to, enlarged, or altered in any manner which increases its nonconformity. If such approval is not sought within one year, any construction must conform to the regulations of the district in which the structure is located. For the purposes of this subsection, "sought" shall require submission of all necessary copies of a full and complete application for site plan review, as applicable, with all required supporting documentation, as certified by the Code Enforcement Officer. Nothing in the subsection should be deemed to prohibit, and the Planning Board is hereby expressly authorized to permit, any changes to the structure which make the structure less nonconforming.
