A special use permit or variance shall expire one  year from the date of granting by the Zoning Board unless the applicant exercises the permission granted or receives a building permit to do so and commences construction and diligently prosecutes the construction until completed. The Board may, upon application therefor, for good cause shown, and following a public hearing thereon, grant an extension for an additional one-year period. Nothing herein contained shall limit the number of successive one-year extensions which the Board may grant, provided that the Board may only grant a single one-year extension following any one public hearing.
