“Site” means a place where a significant event or pattern of events occurred. It may be the location of prehistoric or historic occupation or activities that may be marked by physical remains; or it may be the symbolic focus of a significant event or pattern of events that may not have been actively occupied. A site may be the location of a ruined or now nonexistent building or structure if the location itself possesses historic, cultural or archaeological significance. (Ord. 2069 § 2 (Exh. B), 2011; Ord. 1635 § 1, 1996; Ord. 1258 § 1, 1987).
