The T-R, Threshold Residential District is created to provide for single family detached residences at relatively low densities which are compatible with the Comprehensive Plan's goals for large lot residential development in selected locations in Danville. The average density of two units per net acre establishes the T-R District as the City's second lowest density district for detached residences. The T-R District shall require public water and sewer service, public streets, and pedestrian trails or sidewalks as minimum subdivision improvements. Recognizing prevailing storm drainage deficiencies in and around the City, all new public roads in the T-R District shall be constructed with a storm water conveyance system.

The T-R District may be applied to both undeveloped tracts and to infill lots in existing stable neighborhoods in appropriate locations recognized by the Comprehensive Plan. The intent of the district is to preserve existing natural features and vegetation, promote excellence in site planning and landscape design, facilitate the efficient layout and orientation of public utilities and community infrastructure, and encourage housing with compatible scale and character of architecture. No more than one single family dwelling shall be permitted per subdivision lot. Public water and sewer is required and lots shall not be permitted with private domestic wells or septic systems.
