Expiration of special use permit or variance and repetitive petitions

Unless specifically granted by the board for a longer period of time, a special use permit or variance from the provisions of this chapter shall expire two years from the date granted by the board unless the applicant receives a building permit and commences construction, and diligently prosecutes the construction until completed or obtains a certificate of occupancy where no building permit is required. The board may extend a special use permit or variance for a period of one additional year at a time for good cause shown if a request is received in writing prior to expiration of the decision and voted on at a regular meeting of the board. No reapplication for a special use permit or variance shall be granted without a hearing as specified above. The board shall not accept a second appeal or application which is identical to an appeal or application, which has been adversely decided, for a period of two years from the date in which the decision is recorded and filed unless facts are presented to the board indicating a substantial and specific change in conditions or circumstances relating to the matter.
