2-1. Districts. For the purposes of this ordinance, the city and the area within one and one-half (1½) miles of the city limits of the city is hereby divided into the following districts:

(Ord. No. 22-95, § 1, 3-21-95)

2-2. Maps. The boundaries of these districts are hereby established as shown on the official city zoning map which is on file at city hall and is designated as the zoning district map. The zoning district map and all the notations, references and other information shown thereon are a part of this ordinance and shall have the same force and effect as if such map and all the notations, references and other information shown thereon were all fully set forth or described herein, which zoning district map is properly attested and on file at the city hall in the city. Contiguous territory within one and one-half (1½) miles of the corporate limits of the city is classified for zoning purposes as shown in the extra territorial zoning map, which accompanies and is hereby declared to be a part of this ordinance; and all the notations, references and other information shown thereon are a part of this ordinance and shall have the same force and effect as if such extra territorial zoning map and all the notations, references and other information shown thereon were all fully set forth or described herein, which zoning district map is properly attested and on file with the city clerk.

2-3. District boundaries.

A.

District boundary lines on said map are intended to follow either streets or alleys or lot lines; and where the districts designated on the map are bounded approximately by such street, alley or lot lines, the street or alley or lot line shall be construed to be the boundary of the district unless such boundary is otherwise indicated on the map. In the case of unsubdivided property, the district boundary lines shall be determined by the use of the scale appearing on the zoning district 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 said railroad line.

2-4. All territory which may hereafter be annexed to the city shall maintain the same district designation as is held under the extra territorial zoning map. Any unzoned land lying outside of and contiguous to the zoning boundary one and one-half (1½) miles distant from the corporate limits of the city shall automatically be zoned "NU—Nonurban District" when said corporate limits are changed or altered in such a way that the previously contiguous land then lies within the 1½-mile area.

2-5. Whenever any street, alley or other public way is vacated by official action of the city council, 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.

2-6. Any area within the corporate limits of the city or within one and one-half (1½) miles of the corporate limits of the city which is under water and not shown as included within any district shall be subject to all of the regulations of the district which immediately adjoins the water area. Where said water area adjoins two (2) or more districts, the boundaries of each district shall be construed to extend to the center of the water area.
