[Ord. No. 51, 7-14-1955]
A.
The Board of Aldermen may, upon request by the owner or owners of the property affected, after due public notice and hearings thereon, at which hearings parties in interest and citizens shall have opportunity to be heard as provided herein, amend, change, restrict or extend the boundaries of the various districts established herein. Before taking any action upon any proposed amendment, modification, change, restriction or extension, or change of the "Zoning Code", the same shall be referred by the Board of Aldermen to the Board of Zoning Adjustment, which Board, after due public notice and hearing, shall submit a report to the Board of Aldermen containing its recommendation thereon.
B.
In the case of a protest against any zoning change, duly signed and acknowledged by the owners of thirty percent (30%) or more either of the areas of the land (exclusive of streets and alleys) included in such proposed change or within an area determined by lines drawn parallel to and three hundred eighty-five (385) feet distant from the boundaries of the district proposed to be changed, such amendment shall not become effective except by a favorable vote of two-thirds (2/3) vote of all members of the Board of Aldermen.
C.
If, by amendment of this Chapter, any area is hereafter transferred to another district of higher classification by a change in the district boundaries, a building or use, lawfully existing in such transferred area at the time of such amendment, may be continued in the district to which it is transferred as a non-conforming building or use.
