[R.O. 1997 § 400.660; Ord. No. 1021 Art. 15 § 15-1, 2-1-1966]
In a residential district where open land is being used as a non-conforming use, and such use is the principal use and not accessory to the main use conducted in a building, such non-conforming use shall not be extended, enlarged or changed to another non-conforming use, either on the same or adjoining property. Such non-conforming use of open land shall specifically include billboards, poster boards, automobile wrecking yards, scrap iron and junk storage, auction yards, contractors' yards, stockyards, golf driving ranges and miniature golf courses, and trailer camps or parks not approved under Article XII of this Chapter. If the non-conforming use of such open land ceases for a continuous period of one (1) year, then said property shall not again be used except in conformity with the regulations of the district in which such open land is located.
