A. District boundary lines, as shown on the official zoning map, follow streets, alleys and existing property lines, where feasible. When the district boundary lines do not follow any of these lines, the width or extent of the district may be scaled from the map, unless otherwise provided in this chapter.
B. Whenever a district boundary line does not follow either a street or alley, the less restricted district (industrial district being less restricted than the commercial districts or residential districts, respectively) extends only to the back of the lots where the lots or buildings thereon, or to be constructed thereon, face the least restricted district and cannot face towards the side of a building existing or erected in conformity with subsection A of this section.
C. Whenever any street, alley or public way or railroad right of way is vacated by proper authority, the districts adjoining each of such vacation and all that are included in the vacation shall henceforth be subject to all regulations of the extended districts. (Ord. 1183, 12-12-2005)
