Within selected geographical areas that are designated for mobile homes on the city general plan map, adopted by the city council on January 15, 1974, or zoned RMH on the zoning map, the city council, through conditional use permits, after review by the planning commission, may regulate by districting, the proposed mobile home residential use, manufactured home residential use, and recreational vehicle parks. When such districts are designated, the provisions of this chapter shall prevail over any requirements underlying by virtue of the zoning previously adopted. Within the commercial zoning districts, the appropriate provisions of this chapter shall apply to recreational vehicle (RV) parks approved by the planning commission through conditional use permits.
