The intent of the RE (Residential Estates) district is to provide for the development of single-family dwellings at a density not to exceed one (1) dwelling unit per acre and other selected uses, which are compatible with the large lot, low density character of the district. Property in this zoning district would be located on those tracts which abut or are in close proximity to existing large-lot single-family development and which have an established neighborhood character of single family dwellings on one (1) acre or larger lots. Land considered for RE zoning should also include only that land which, due to its location of conditions resulting from adjacent large-lot residential development, will not be provided with public sanitary sewers within a reasonable period of time, or are in areas which can be sewered, and are located adjacent to ridgelines or near other large-lot subdivisions developed prior to adoption of these regulations.
