(a) The district boundary lines on the Zoning Map are intended to follow either street, alley or lot lines and where the districts designated on the Zoning Map are bounded approximately by such street, alley or lot lines, the street, alley or lot line shall be construed to be the boundary of the district unless such boundary is otherwise indicated on the Zoning Map. In the case of unsubdivided property, the district boundary lines shall be determined by the use of the scale appearing on the Zoning Map or by dimensions.
(b) Where the boundary of a district follows a railroad line, such boundary shall be deemed to be located midway between the main tracks of the railroad line.
(c) All territory which may hereafter be annexed to the Municipality shall be automatically classified in the R-1 Residence District unless Council enacts an ordinance, effective the same date as the ordinance or resolution accepting annexation of such territory, providing for use classification of such territory as an R-2 Single- Family Residence District, an R-3 Single-Family Residence District, an R-4 Multiple-Family Residence District, a B-1 Highway Commercial District, a B-2 Central Business District, an I-1 Light Industrial District, or an I-2 Heavy Industrial District. No such ordinance providing for a use classification of newly annexed territory shall be enacted as an emergency.
(d) No district established in this Zoning Code shall be created, amended, changed or modified in such a manner as to create a free-standing district of less than five acres in area. For the purpose of determining compliance with this section, the area composed of public right-of-ways within the district shall also be included in the area computations.
(e) Whenever any street, alley or other public way is vacated by the legislative authority, the zoning district adjoining each side of such street, alley or public way shall be automatically extended to the center of such vacation, and all area included in the vacation shall then and henceforth be subject to all appropriate regulations of the extended districts.
