The following transitional provisions shall apply to activities, actions and other matters pending or occurring on the effective date specified by the provisions of Section 901.05.
A. 
Violations Continue. Any violation of the zoning regulations in effect before the effective date specified by the provisions of Section 901.05 shall continue to be a violation under this Code and shall be subject to penalties and enforcement under Chapter 924, unless the use, development, construction or other activity is clearly consistent with the express terms of this Code.
B. 
Nonconformities Under Previous Ordinance. Any legal nonconformity under the zoning regulations in effect before the effective date specified by the provisions of Section 901.05 shall be considered a legal nonconformity under this Code, so long as the situation that resulted in the nonconforming situation under the previous regulations continues to exist. If, however, a nonconformity under a prior ordinance becomes conforming because of the adoption of this Code or any subsequent amendment to this Code, then such situation shall no longer be considered a nonconformity.
C. 
Completion of Development Plans. Any building or development for which a permit was issued or for which complete plans were submitted before the effective date specified by the provisions of Section 901.05 may be completed in conformance with the issued permit and other applicable permits and conditions, including the plans submitted for the approval of the permit, even if such building or development does not fully comply with the provisions of this Code. If construction is not commenced or completed in accordance with the applicable permit terms, the Zoning Board of Adjustment may, for good cause shown, grant not more than one (1) extension of up to six (6) months for such construction. If the building or construction is not completed in a timely manner, within the time allowed under the original permit or any extension granted, then the building may be constructed, completed or occupied only in strict compliance with the requirements 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.
