The purpose of Article XI is to regulate the location and design of RMDs in such a manner as to create neighborhoods designed for long-term occupancy, to ensure compatibility with surrounding areas and with the natural environment, and to provide safe, sanitary and attractive living conditions for occupants of mobile homes located in such parks. There shall be no creation, extension or expansion of any mobile home park after an amendment of this ordinance, unless such creation, extension or expansion is in conformance with all ordinances concerning RMDs.
