[Ord. No. 875-17 § 1, 1-18-2017]
A. 
The intent of this Article is to provide, with the granting of a special use, a voluntary and alternate zoning procedure in the "R-1" and "R-2" residential zone districts, to permit flexibility in building types and arrangements that would not be possible under the strict application of the zoning district, encourage a creative approach to the use of land and related physical facilities that result in better design to preserve existing site topography, major tree cover and natural water features on and adjacent to the development and to contribute to the enhancement of the City's urban design with attention to abutting neighborhoods and roadway systems.
B. 
This district is intended for attached single-family structures separated into two (2) owner-occupied living units. They include common wall construction, individual garages, private yards, landscaped common areas, and homeownership is required.
C. 
Maintenance of the public and private outdoor areas is provided by a property management organization.

The mean average of the unit lots of the development will be no less than 1 acre in "R-1" and 1/2, acre in "R-2." Common ground can be added to affect the average. Roads and other similar facilities can be considered common ground for the purposes of calculating density.
C. 
Single-family attached dwellings shall not form long unbroken lines of row housing. Moreover, no more than two (2) contiguous single-family attached dwellings shall be built with the same front line. The required difference in front lines shall be a minimum of three (3) feet. It is preferred that the dwellings be arranged in groupings to allow for more efficient use of land and provide for more open space.
