Abandonment. Each and every nonconforming building structure and use shall terminate upon abandonment. When a nonconforming use of/or a structure, or the nonconforming use of a structure and lot in combination, is discontinued for a period of 12 consecutive months, the nonconforming use shall be presumed to be abandoned, and the structure or structure and lot in combination, as the case may be, shall not thereafter be used except in conformance with the regulations of the zoning district in which it is located, unless the owner can establish that abandonment has not occurred. Any structure, or structure and lot in combination, in or on which a nonconforming use is superseded by a permitted use must thereafter conform to the regulations of the zoning district in which said structure is located, and the nonconforming structure or use shall not thereafter be reinstituted. The Zoning Officer shall determine abandonment and shall be informed by any action, or lack thereof, to further signify that a use has been terminated. Such as indicators may include removal of essential equipment, removal of signage, removal of inventory, removal or semipermanent disconnection of utilities, de-facto cessation of operations, a record of chronic failure to maintain property in accordance with property maintenance codes, declaration of unsafe building, condemnation, evidence of chronic dumping, vandalism or other vice. The Planning Board shall hear appeals of this decision.
