The purpose of the RE zone is to accommodate very low density residential uses. It applies primarily to areas impacted by high noise levels; areas within designated approach or clear zones around airports; areas within identified floodway and floodway fringe areas; and other areas where physical or safety considerations necessitate very low density residential use. This zone is designated as "RE" with a suffix indicating one unit per a minimum number of acres (i.e., RE-1/4, RE-1/2, RE-1/1, RE-1/.5). (Ord. 2013-0020 § 1; Ord. 2013-0007 § 1)
