   A.   Map Adopted: The boundaries of the various zoning districts are hereby fixed and established as shown on the zoning map. The zoning map is on file in the office of the village clerk. The map is hereby adopted and made a part of this title as if the matters and information set forth by said map were fully described herein.

   B.   Changes To Map:

      1.   Compliance With Provisions; Unauthorized Changes: No changes or amendments to the official zoning map shall be initiated, except in compliance and conformity with all procedures and requirements of this title. It shall be unlawful for any person to make any unauthorized change in the official zoning map.

      2.   Time For Publication: In accordance with state law, if any changes are made in the zoning districts or regulations during a calendar year, the village clerk shall publish the official zoning map of the village not later than March 31 of the following year. (Ord. 96-21, 9-10-1996)

The boundaries of the various districts as shown on the zoning map shall be determined by the boundaries as shown and outlined thereon and when not clearly so determined, by use of the scale shown on said map unless actual dimensions are noted. Scale and field measurements and map dimensions shall be figured from the center line of streets, highways, alleys and railroad rights of way as appropriate. Where uncertainty exists as to the exact location of said boundaries, the following rules shall apply:

   A.   Center Line As Boundary: Where district boundaries lie on or within streets, highways, road rights of way or railroad rights of way, the district boundaries shall be the center line of the same.

   B.   Boundaries Which Bisect Blocks: Where district boundary lines approximately bisect blocks, the boundaries shall be the median lines of such blocks between the center line of boundary streets.

   C.   Boundaries Dividing Parcels Of Land: In subdivided property or where a district boundary divides a subdivided lot, the location of such boundary, unless the same is indicated by dimensions, shall be determined by the use of a scale appearing on the district map. Where a district boundary divides a platted lot, the zone classification of the greater portion shall prevail throughout the lot.

   D.   Uncertainty Settled By Board Of Zoning Appeals: In case any further uncertainty exists, the board of zoning appeals shall interpret the intent of the zoning map as to the location of such boundaries.

   E.   Street And Right-Of-Way Abandonments: Where a public road, street, alley or other right of way is officially vacated or abandoned, the regulations applicable to the property to which it reverted shall apply.

   F.   Excluded Areas: Unless areas are classified on or by the official zoning map of the village or the appropriate classification can be established by the rules above, such areas shall be considered to be classified as A-1 agricultural district, until such time as the land is rezoned by the village board of trustees. (Ord. 96-21, 9-10-1996)

Any territory hereafter annexed to the village shall automatically be zoned as RS-10 single-family residential district, until duly changed by an amendment to this title except under the following conditions:

   A.   The village board, with the recommendation of the planning and zoning commission, may annex any territory as any other zoning district or districts herein established if all legal requirements for zoning the property at the time of the annexation are recorded.
