§ 155.311 PLANNED RESIDENTIAL UNIT DEVELOPMENT.
   It is the purpose of this section to encourage more imaginative and livable housing environments within the residential districts, as noted, through a planned reduction, or averaging, of the individual lot area requirements for each zone district; providing, the overall density requirements for each district remains the same. The averaging or reduction of lot area requirements shall only be permitted when a land owner, or group of owners acting jointly, can plan and develop a tract of land as one complex land use unit, rather than an aggregation of individual buildings located on separate, unrelated lots. Under these conditions, a special use permit may be issued for the construction and occupancy of a planned residential unit development providing the standards, procedures and requirements set forth in this section can be complied with.
   (A)   Objectives.
      (1)   To provide a more desirable living environment by preserving the natural character of open fields, stands of trees, brooks, ponds, flood plains, hills and similar natural assets;
      (2)   To encourage the preservation of open space and the development of recreational facilities in a generally central location and within reasonable distance of all living units;
      (3)   To encourage developers to use a more creative and imaginative approach in the development of residential areas;
      (4)   To provide for more efficient and aesthetic use of open areas by allowing the developer to reduce development costs through the bypassing of natural obstacles in the residential site; and
      (5)   To encourage variety in the physical development pattern of the community by providing a variety and mixture of housing types.
   (B)   Applicability. The provisions of this section, shall take precedence when in conflict with other section of the Zoning Ordinance.

      (1)   The acreage of the site, computed from the legal description of the parcel being developed shall be used for all calculations related to density and open space. The gross acreage shall be used. No factors for rights-of-way or easements will be considered. The perimeter setbacks and building heights shall meet the requirements of the zoning district in which the parcel is located.
      (2)   Minimum size of the development shall be six acres.
   (F)   Open space requirements.
      (1)   There shall be a minimum of 10% open space. There is no maximum amount of open space that may be set aside as open space.
