The purpose of this district is to promote a low density residential development in areas generally adjacent to the built-up portions of the community, thereby providing a more orderly extension of public facilities by encouraging redevelopment to take place in these areas. The district recognizes the community's housing demand for single-family dwellings and the sociological and economic reasons for providing these in areas excluding two-family and multi-family units. Therefore, the district is established and located in sections of the community presently dominated by single-family dwellings.
