This chapter is intended to identify those structures and uses for which standard height limits are not appropriate and to provide review procedures and criteria for those special situations where the height restrictions of this title may be relaxed. Performance-based height exceptions are intended to allow structures that require height in excess of height limits for effective performance and operation. Performance-based height exceptions are not intended to be used as a means of circumventing individually inconvenient height restrictions. (Ord. 988 § 1, 2005; Ord. 950 § 1, 2004).
