§ 153.167  PLANNED UNIT DEVELOPMENT.
   (A)   Districts permitted. A planned unit development (PUD) shall be permitted in the following zoning districts: R-1, R-2a, and R-3.
   (B)   Special use permit. A planned unit development (PUD) shall require a special use permit with site plan approval by the Planning Commission and must be in accordance with all standards, procedures, and provisions set forth in §§ 153.075 through 153.081, 153.095 through 153.100, and 153.165 through 153.170.
   (C)   Site eligibility.  The minimum area necessary to qualify as a PUD shall not be less than ten contiguous acres of land.  However, an owner of land less than the minimum required area may apply if the subject land is adjacent to a lawfully approved or constructed PUD which is similar in character to the one proposed.
   (D)   Density and open space requirements for PUDs.  As a planned single unit, a PUD may be constructed in any combination of residential uses and structures (except mobile homes), provided that:

      (2)   At least 25% of the total area is reserved for open space.  OPEN SPACE is defined as an area which may consist of land included as part of the required yard setbacks, roads, greenbelt areas, drainage easements, open space, or any outdoor recreational amenity; but shall not include any area used for structures, or off-street parking and loading; and
      (3)   Full compliance with the provisions of this chapter and the tables/schedules contained herein, shall be met, unless waived by the Planning Commission serving as the special use review and approval body.
   (E)   Residential density bonuses.  Bonuses in net residential density for PUD development are permitted by the Planning Commission, provided that additional land is reserved and dedicated for open space (as defined above) as follows:
