A. Where, on September 11, 1978, or at the effective date of an amendment of these zoning regulations, lawful uses of land exist that are no longer permissible under the terms of these zoning regulations as enacted or amended, such uses may be continued so long as they remain otherwise lawful, subject to the following conditions:
1. No such nonconforming use shall be moved, in whole or in part, to any other portion of the lot or parcel occupied by such use at the effective date of the adoption or amendment of these zoning regulations;
2. No such nonconforming use shall be enlarged or increased or extended to occupy a greater area of land than was occupied at the effective date of the adoption or amendment of these zoning regulations; and
3. If any such nonconforming use of land ceases for any reason for a period of more than sixty (60) days, any subsequent use of such land shall conform to the regulations specified by these zoning regulations for the zoning district in which such land is located.
B. A nonconforming use of a structure or of a structure and land in combination shall not be changed unless changed to a use permitted in the zoning district in which it is located, including a use permitted on review. Such change shall be construed as an abandonment of the former nonconforming use.
