Expiration of variances. Any variance from the zoning regulations shall expire by limitation unless the construction, alteration or use, as applicable, permitted by the variance shall have been actually commenced within 12 months of the date of memorialization of approval of the variance; provided, however, that the running of the period of limitation herein provided shall be tolled in the case of legal action as provided in §
184-68. Notwithstanding the foregoing, any variance hereafter granted in connection with a subdivision or site plan application shall not expire as provided above, but shall expire in the same manner as the subdivision or site plan approval, as applicable, as set forth in Article
IX.
