The official zoning map shall be displayed at all times in City Hall and shall bear a certificate with the signature of the mayor and the certification of the city clerk and the date of the adoption of the ordinance codified in this title. If any changes to the map are made by amendment of the ordinance codified in this title, such changes shall be made to the official zoning map and signed and certified upon the map or upon material attached thereto. (Ord. 965-05 § 3; Ord. 817 § 2, 1996).

In the event that the official zoning map becomes damaged, lost or difficult to read or interpret because of the number or nature of changes thereto, a new official zoning map shall be prepared and shall be approved for certification by the city council and signed by the mayor, and certified as the official zoning map by the city clerk. (Ord. 817 § 2, 1996).

Where uncertainty exists as to the boundaries of districts as shown on the official zoning map, the boundaries shall be interpreted as following the nearest logical line to that shown: where shown as approximately following platted lot lines, it shall be construed as following such lot lines; where shown as following approximately the city limits, railroad tracks, street centerlines, stream or water centerlines or shorelines, it shall be construed as following such lines. Boundaries indicated as extensions of or parallel to such lines shall be so construed and where distances are now shown on the map, they shall be determined by the scale of the map. Where boundaries cannot be so construed or interpreted, or where such boundaries seem in conflict with physical or cultural features on the land, the planning commission shall interpret such boundaries. (Ord. 817 § 2, 1996).

Whenever any street or alley shall be vacated such street or alley or portion thereof shall automatically be classified in the same zoning district as the property to which it attaches. (Ord. 817 § 2, 1996).

All territory which may hereafter be annexed to the city shall be considered to be zoned in the same manner as the contiguous territory inside the previous city limits, until otherwise classified. (Ord. 817 § 2, 1996).
