§ 154.119  PLANNED UNIT DEVELOPMENT.
   (A)   Intent. This section is intended to encourage innovation in land use patterns and variety in design for development of parcels as well as encouraging economy and efficiency in provision of public services, the use of land, natural resources and energy. These regulations provide flexibility for developers while protecting public values.
   (B)   Permitted uses and standards.
      (1)   A planned unit development (PUD) may include all uses by right and special uses listed for the zoning district that applies to its site, and for the zoning district that immediately precedes and follows it in the following list of districts:
         (a)   R-1;
         (b)   R-2;
         (c)   R-3;
         (d)   B; and
         (e)   I.
      (2)   For example, a PUD proposed for a parcel zoned R-2 could include all uses identified for the R-1, R-2 and B Zoning Districts.
      (3)   When a Use is listed only as a special use for the applicable zoning districts, all special use permit standards for said use will apply. When a use is listed as a special use in one of the applicable zoning districts, and as a use by right in another, it may be treated as a use by right for the PUD.
   (C)   Use density and parcel coverage. Parcel coverage limits for the applicable zoning district must be met overall, with the following additions.
      (1)   Residential coverage in business zoning districts. For a PUD located in the B Zoning Districts, up to 50% of the allowable parcel coverage may be devoted to structures for residential uses.
      (2)   Nonresidential coverage in residential zoning districts. For a PUD located in the R-1 or R-2 Zoning Districts, up to 20% of the allowable parcel coverage may be devoted to structures for nonresidential uses.
      (3)   Residential density. The maximum residential density shall be one dwelling unit for every 4,000 square feet of parcel area. Single-family or two-family dwellings shall meet the dwelling unit area requirements specified for the R-2 Zoning District. Multiple-family dwellings shall conform to the R-2 requirements.
   (D)   Dimensional requirements. Front yard setback requirements for the applicable zoning district shall apply to all boundaries of the PUD. Building height limitations and minimum yards between dwelling structures shall be as specified for the C-1 Zoning District; however, if plots of land in a PUD are proposed for resale as either fee simple parcels or site condominiums, said parcels or condominium units, and any buildings thereon, must meet the parcel dimension and yard requirements for the R-3 Zoning District.
   (E)   Buffering for residential uses. When a PUD contains a mix of residential and other uses, the following provisions shall be enforced.
      (1)   Separate buildings. In any PUD, a building devoted to nonresidential use must be separated from adjacent residential buildings by a yard area not less than 30 feet across, developed as landscaped open space and not used for parking or circulation of motor vehicles. This area may apply toward satisfaction of the PUD’s open space requirement, as noted below.
      (2)   Within same building. When residential and nonresidential uses occupy space in a single building in a PUD, a continuous physical separation must be provided between spaces devoted to said uses. Access doorways are allowed, but the separation must provide at least a one-hour fire rating between residential and nonresidential space.
   (F)   Open space. At least 10% of any parcel containing a PUD must be devoted to landscaped open space. Forest, wetland or other unique environmental areas may be left in a natural state. Cropland may not be counted as landscaped open space, nor may yard areas of individual residential lots be included; however, landscaped yard areas for multiple dwellings or nonresidential uses may be included. If the PUD includes multiple dwellings, it must have at least 1,000 square feet of open space per dwelling unit.
   (G)   Parking and circulation. Parking for uses in a PUD shall conform to the requirements of individual uses. Roadways in a PUD are intended to be public streets, and must be built to the standards of the applicable public agency.
