Except as modified elsewhere in this Ordinance, if a nonconforming use is discontinued for one hundred eighty (180) calendar days or more, then the property shall thereafter be occupied and used only for a conforming use. If a nonconforming use of property is discontinued, but re-established within one hundred eighty (180) calendar days, then the nonconforming use may continue, if the nature and degree of the nonconformity will not be changed or increased from that which existed before the nonconforming use was discontinued.
