(A) The gross area of a tract of land to be developed in a planned unit development district shall be a minimum of ten acres, provided however, that smaller parcels may be considered on the basis of their potential to satisfy the objectives of this subchapter as stated in § 154.205.
(B) When the planned unit development proposes a mixture of residential uses with commercial, professional and/or industrial uses, the Planning Commission may limit the development to not more than 8% of the tract to commercial/professional uses and not more than 12% of the tract to light industrial uses.
(1) Minimum lot sizes. Lot area per dwelling unit may be reduced by not more than 40% of the minimum lot area required in the district regulations in §§ 154.075 through 154.090 on sanitary sewer. A planned unit development need not conform to the density requirements of §§ 154.075 through 154.090 on sanitary sewer. A diversification of lot sizes is encouraged on sanitary sewer. Lots widths may be varied to allow for a variety of structural design. It is also recommended that setbacks be varied.
(2) Height requirements. For each foot of building height over the maximum height regulations specified in §§ 154.075 through 154.090, the distance between such buildings and the side or rear property lines of the planned unit development project area shall be increased by one foot addition to the side and rear yard required in the districts.
(3) Parking. Off-street parking, loading and service areas shall be provided in accordance with §§ 154.165 through 154.172. However, off-street parking and loading areas shall not be permitted within 15 feet of any residential use and shall be screened with fence or vegetation approved by the Planning Commission.
(5) Lots to abut upon common open space. Every property developed under the planned unit development approach should be designed to abut upon common open space or similar areas. A clustering of dwellings is encouraged. In areas where townhouses are used, there shall be no more than eight townhouse units in any contiguous group.
