§ 153.022 ZONE MAP.
   (A)   Zone Map. The Zone Maps, which accompany this chapter, show the boundaries of and the area covered by the districts. These maps are incorporated by reference into this chapter, with two copies being on file in the office of the City Clerk and available for public inspection. The notations, references, indications and other matters shown on the Zone Maps are as much a part hereof as if they were fully described herein.
   (B)   Boundaries: in general.
      (1)   The boundaries of the districts established by this section are as shown on the Zone Maps, which are a part of this chapter. Such boundaries may be changed only by amending this chapter.
      (2)   The exact location of split zone boundaries in regards to individual tracts of land shall be determined as follows.
         (a)   When the exact boundaries of a district are uncertain, they shall be determined by use of the scale of the Zone Map.
         (b)   When a right-of-way is vacated, the districts adjoining each side are respectively extended to the center of the area so vacated.
         (c)   If the boundary line of a district divides a lot having frontage on a street so that the front part of the lot lies in one district and part of the lot lies in another, the restriction that applies to the front part of the lot applies to the entire lot.
         (d)   If the boundary line of a district divides a lot in a manner essentially perpendicular to a street, that restriction which applies to the larger part of the lot applies to the entire lot.
         (e)   If the boundary of a district divides a through lot, the district that applies to the greater frontage applies to the entire lot, except that if one frontage is designed arterial, the district of that frontage shall apply. If the frontage is equal, the Board shall determine the intent of the Zone Map.
         (f)   In the case of further uncertainty, the Board shall interpret the intent of Zone Map as to the location of the boundary in question.
      (3)   In the event of annexation of lands to the city or a town, the zoning classification existing at the time of annexation shall remain until changed by amendment procedures.
   (C)   Boundaries: in Shopping Center Districts. Boundaries in Shopping Center Districts are affixed by the Commission and posted by it on the Zone Map. Each such District shall be at least six acres in area and some part of it shall be within 1400 feet of the location corresponding to the location of an SC symbol shown on the Zone Map. The location of such a symbol may be changed only by amending this chapter.
