Upon application, evaluation, and written approval of the director, any part of a building, structure, or land occupied by a nonconforming use may be changed to a use which has the same land use impacts as the legally nonconforming use or a use currently permitted by the zoning code; but where the use of a nonconforming building, structure, or land is changed to a use that is more consistent with the current code, the nonconforming building, structure or land use shall not revert to the prior use.

C. Signs that are left blank, unused, or advertise a business that is no longer licensed by the city of North Bend for operation at the location of the sign for a period of one year as specified in subsection A of this section are determined to be a nonconforming use per this section and an abandoned sign.

(Ord. 1256 § 1 (part), 2006: Ord. 1020 (part), 1997).
