Section 1205.06    District 3: Outer Village Residential Neighborhood

  1. Purpose
    District 3 is established to preserve and protect an existing community character
    typified by single-family detached residential housing developed at moderate
    densities averaging about 2 dwelling units per acre. Being relatively closer to the
    Village Core, neighborhoods in this district have greater accessibility and connection
    to the Village Core than residences in District 1. Existing single-family
    developments are characterized by traditional subdivision designs with curvilinear
    street patterns and some examples of open space dedications. Few potential
    development areas remain, and are constrained in many instances by the Brandywine
    Creek drainage corridor. District regulations are intended to continue the
    predominant single-family detached use, while providing for the addition of attached
    single family, duplexes, and townhomes, into the housing mix, as well as additional
    parks, open space, and trail/bikeway linkages to the Village Core. Additional uses
    include supporting institutional uses (such as churches and schools) and public
    service uses. Single-family detached residential housing densities will mirror
    existing densities and character, and be permitted up to a maximum of 2.5 dwelling
    units per acre. Protection of remaining sensitive environmental areas, including
    wellhead protection areas, will be a high priority.
