Any improved lot that does not conform to the minimum requirements of lot area, setbacks and/or frontage because of alteration or reduction by condemnation, shall be considered conforming; except, that setbacks may be changed by the Planning Commission if found to be harmful or injurious to adjacent properties or if it would constitute a traffic hazard. Any vacant lot made nonconforming, whether improved or unimproved, prior to condemnation shall be considered nonconforming and subject to review by the Zoning Administrator for feasibility of development prior to issuance of any building permit. (Ord. 1356 § 1, 1971; Ord. 1212 § 1, 1969; prior code § 33.1001(G)).
