Statement of intent. The R-1 District is generally composed of quiet low-density residential areas, plus undeveloped areas where similar residential construction appears likely to occur. The standards set forth for this district are designed to stabilize and protect the essential character of the Town, to promote and encourage a suitable environment for residential growth and allow for the optional development and redevelopment of land consistent with the design principles of traditional neighborhoods where deemed appropriate by the Planning Commission and Town Council. Development should be compact and designed for the human scale while providing a mix of housing styles, types and sizes to accommodate households of all ages, sizes and incomes. A mix of uses may be provided for, including single-family detached dwellings, secondary dwelling units, attached single-family dwellings, including duplexes and townhouses, selected commercial uses, and open space uses such as squares, greens, neighborhood parks and linear environmental corridors owned and maintained by a homeowners' association that serve the residents of the development. When new development and redevelopment are planned within or adjacent to a previously developed area, existing buildings with historic or architectural features that enhance the visual character of the Town shall be retained.
