A. 
Adoption. The boundaries of the zoning districts established by this Code shall be shown on a map or series of maps designated as the "Zoning District Map", which is adopted as part of this Code. Original copies of such maps and all amendments thereto shall be maintained in the office of the Zoning Administrator. In case of any dispute regarding the zoning classification of property subject to this Code, the original copies maintained by the Zoning Administrator shall control.
B. 
District Boundaries. The following provisions shall govern interpretations regarding the location of zoning district boundaries shown on the zoning map.
1. 
Streets and Ways. A zoning district boundary shown as approximately following a street or way shall be construed to be in the center of the street or way. If the street or way is vacated, its centerline shall remain the district boundary until the boundary is changed by a zoning map amendment.
2. 
Lot Lines. A zoning district boundary shown as approximately following the boundary line of a recorded lot or separate parcel of land shall be construed to be the boundary of the recorded lot or parcel of land. If a recorded lot line cannot be used to determine the boundary, its location shall be determined by use of the scale shown on the Zoning District Map.
3. 
Uncertainties. Where physical features existing on the ground contradict those shown on the official zoning map, or in case any other uncertainty exists regarding the boundary of zoning districts, the location of district boundaries shall be determined by the Zoning Board of Adjustment in accordance with the procedures of Section 923.02.B.
C. 
Environmental Overlay District Boundaries. The boundaries of the Environmental Overlay Districts are intended to correspond to the location of the regulated or protected natural resources. The boundaries of those districts are based upon the best information available at the time of enactment. If land is determined to be incorrectly included within an Environmental Overlay District, the boundary shall be amended in accordance with the Zoning Map Amendment procedures of Section 922.05.
