If building permits are not issued for site development authorized by variance (if building permits are required) within three (3) years of the date of approval or such longer time as may be stipulated as a condition of approval, the variance shall expire. Upon written request received prior to expiration, the Director may grant renewals of variance approval for successive periods of not more than one (1) year each. Approvals of such renewals shall be in writing and for a specific period. Renewals may be approved with new or modified conditions upon a finding that the circumstances under which the variance was originally approved have substantially changed. Renewal of a variance shall not require public notice or hearing, unless the renewal is subject to new or modified conditions. In order to approve a renewal, the Director must make the findings required for initial approval. (Ord. #248-2020, S2 (Exh. A))
