An approved planned unit development and final development plan automatically expire 2 years after the date of approval if:a building permit has not been issued; or the installation of required infrastructure has not begun. The Planning Commission may extend the time for expiration of an approved planned unit development and final development plan on:a written request for extension that is submitted before the expiration; and for good cause shown. The Planning Commission must conduct a public hearing to determine whether to terminate or extend the approval. In making its determination, the Planning Commission must take into account:hardship to the applicant; changes in surrounding circumstances that have occurred since the original approval; the schedule for providing required public benefits and amenities; and the likelihood that substantial construction will occur during any period of extension.
