In the event of fire, flood or other disaster or unforeseeable event, the Zoning Administrator, upon approval by the Planning Commission and in accordance with conditions established by the Planning Commission, including time limits, may issue a temporary zoning certificate for a period the Zoning Administrator deems appropriate, but in any event not longer than one year, which would allow a temporary relocation of an existing use, whether conforming or nonconforming, to any property within the City limits no matter how the proposed temporary location is zoned.
