Prior to the adoption of Ord. 2005-07 on 06/01/2005, Section 16.04.410 read as follows.

    The use of land that legally existed before its current zoning  land use designation; has been maintained continuously since the time the zoning land use regulation governing the land changed; and because of subsequent zoning  land use ordinance changes, does not conform with the zoning  land use regulations that now govern the land.
