A. Unless a longer time is specifically established as a condition for approval, a variance approval shall lapse and shall become void if not exercised within one (1) year from the date of approval. For a permit to be considered “exercised,” substantial improvement to the land must be performed within one (1) year from the date of approval. Substantial improvement is determined as the completion of fifty (50) percent or more of the total authorized improvements as determined by cost.

B. A variance approval subject to lapse may be extended by the planning commission for an additional period of up to one (1) year; provided, that prior to the expiration date, a written request for extension is submitted to the planning commission and good cause for the extension is shown. [Ord. 01-05 § 8.]
