Section 1205.07    District 4: Historic Residential Neighborhood

  1. Purpose
    This District is established to preserve and protect the residential neighborhoods in
    the city's historic district. These neighborhoods, while containing some multi-family
    and single-family attached units, are dominated by a significant number of historic
    detached homes with relatively shallow setbacks and yard depths. Densities are
    relatively high, with lot sizes generally less than 30,000 square feet. There are strong
    connections and easy accessibility to the Village Core; however, increasing traffic
    congestion is a growing detriment to the quality of life in this District's residential
    neighborhoods. There are few environmental constraints on new development, but
    there also are few potential development areas. The regulations contained in this
    District are intended to permit compact residential densities, including multi-family
    residential uses, while assuring compatibility with existing residential neighborhoods
    and their historic character and strengthening this District's linkages with the Village
    Core. Potential traffic impacts from new developments will be scrutinized as part of
    the development approval process.
