1205.04   DISTRICT 1: SUBURBAN RESIDENTIAL NEIGHBORHOOD.
   (a)   Purpose. District 1 is established to preserve and protect an existing community character typified by single-family detached residential housing developed at densities varying from one dwelling unit per one-half acre to one dwelling unit per two and one-half acres. The district is relatively more rural in density given its distance from the Village Core. The amount of prior development has left few environmental constraints on additional development; on the other hand, there remain few potential development areas. District regulations are intended to continue the predominant single-family detached use, while providing for additional parks and open space, supporting institutional uses (such as churches and schools), and public service uses. Densities will mirror existing densities and character, and be permitted up to a maximum of two dwelling units per acre. Protection of remaining sensitive environmental areas will also be a high priority.
