A.   Map Established: The boundaries of the districts described above are shown on the map that is on file in the office of the city manager and incorporated herein and made a part hereof by reference, which map is designated as the zoning district map. Said district map and all notations, references and other information shown thereon are made a part of this title and shall have the same force and effect as if said map and said data thereon were fully set forth or described herein. Said map shall, on its face, be identified and verified in the manner following: it shall bear the title "Zoning District Map - Alamo, Texas"; it shall bear the name of the mayor and it shall be attested by the signature of the city secretary. The original of said map shall be kept in a proper place in the municipal building.

   B.   Vacations: Whenever any street, alley or public way is lawfully vacated by the board of commissioners of the city, the zoning district adjoining each side of such street, alley or public way shall be automatically extended to the center of such vacated area thereafter all land included in said districts.

   C.   Annexations: Whenever any property is annexed into the city such property shall be added to the zoning map and be assigned to a district in accordance with the zoning ordinance passed after the effective annexation. If the use of such property cannot be wholly determined then such property shall be given a temporary zoning classification as R-1. (Ord. 95-04-04, 4-4-1995)

Where uncertainty exists with respect to the boundaries of the various districts as shown on the map made part of this title, the following rules apply:

   A.   The district boundaries are either streets or alleys unless otherwise shown, and where the districts designated on the map made a part of this title are bounded approximately by street or alley lines, the street or alley shall be construed to be the boundary of the district.

   B.   Where the district boundaries are not otherwise indicated and where the property has been or may hereafter be divided into blocks and lots, the district boundaries shall be construed to be the lot lines, and where the districts designated on the map made part of this title are bounded approximately by lot lines, the lot lines shall be construed to be the boundary of the district unless the boundaries are otherwise indicated on the map.

   C.   In subdivided property, the district boundary lines on the map made a part of this title shall be determined by the use of the scale appearing on the map. (Ord. 95-04-04, 4-4-1995)
