R1
Residential Low Density Zone
This zone is intended for low-density, single-family residential areas, which will provide a suitable environment for family life for residents. The zone is intended to provide a quiet living environment free from rooming and boarding houses, commercial and industrial activities, and, to the greatest degree possible, free from other than local vehicular traffic. All new development in this zone shall be compatible with the immediate residential neighborhood with respect to scale, mass and height. The purpose of this zone is to allow low-profile, single-family residences that preserve existing public and private views and minimize building mass and bulk in a manner that is sensitive to their terrain and to environmental constraints.
