The RA residential acreage district is intended to provide living area which combines certain of the advantages of both urban and rural location by limiting development to very low density concentrations of one-family dwellings as designated by the general plan, and permitting limited numbers of animals and fowl to be kept for pleasure or hobbies, free from activities of a commercial nature. The RA district is intended to encourage the use of the subdivision or parcel map process in the creation of large residential sites to assure the provision of those physical improvements necessary to protect the health, safety and general welfare of the people.
