Official zoning maps designating the exact boundaries of each zone, as adopted by the hearing examiner and/or county council, shall be available for public review at the department during business hours. The location and boundaries of the zones shall be shown on the official zoning maps and subject to the following rules of interpretation:
(b) Unless otherwise referred to established points, lines, or features, the zone boundary lines are the centerlines of streets, public alleys, parkways, waterways, or railroad rights-of-way. In the case of navigable water, the outer harbor line shall be the boundary line. If the outer harbor line is not established, then the zone boundary shall extend 500 feet from the ordinary high water mark; and
(c) Zone classification will not change as a result of vacating a street or alley. The boundaries originally established will continue to apply. (Added by Amended Ord. 02-064, Dec. 9, 2002, Eff date Feb. 1, 2003).
