   (A)   Purpose.
      (1)   The regulations contained in this section are established to achieve or otherwise promote one or more of the following amenities or objectives in a new development: (a) imaginative design; (b) preservation of natural features such as floodplains, woodlands, wetlands, bluffs and ravines; (c) open space; (d) landscaped berms and buffers; (e) recreational facilities; (f) stormwater retention facilities; (g) diverse housing types and housing types that are available only in limited supplies in the community; (h) housing that supports alternative modes of fransportation through proximity to train stations, bicycle and pedestrian paths and similar facilities; (i) development that supports and brings vitality to the business districts; and (j) housing near community institutions or (k) such other amenities as the City Council may determine will serve the purposes of this section and be in the public interest. The standards contained in this section and § 159.048 are intended to provide a development alternative to the zoning standards applicable to the underlying zoning for the property. To be eligible for approval, proposed developments must, in the determination of the City Council based on consideration of the findings and recommendation of the Plan Commission: (a) serve the purposes stated in this division (A); (b) comply with all applicable requirements of this § 159.047, including the standards stated in the appropriate section of division (A)(2), below; (c) be in the public interest; (d) be compatible with the character of the city; and (e) be in accord with the principles set forth in the Comprehensive Plan of the city.
      (2)   Additionally, each of the individual types of planned developments was created for the following purposes:
         (a)   Planned preservation subdivision development. The planned preservation subdivision provisions, as further set forth in § 159.048, permit creation of developments which preserve and protect architecturally significant homes and estates, significant parts of the landscape heritage of the city or significant natural resources including, but not limited to, woodlands, prairies, wetlands, flood plains, and environmentally sensitive or significant open space, through the dedication or establishment of common open space and the use of innovative subdivision design techniques for single-family dwellings in residential disfricts. Notwithstanding anything in this section or § 159.048 to the contrary, the City Council may approve a planned preservation subdivision design that deviates from the generally applicable development standards of Chapters 156 and 159 of the city code (including, but not limited to, standards pertaining to the size, shape, and number of lots; density; setbacks; and building areas) if the City Council determines that such design will serve one or more of the purposes described in this paragraph.
         (b)   Planned multi-family development. The planned multi-family development provisions are established to provide a safe and desirable living environment characterized by a unified building and site development plan, to preserve natural features of the site, to provide adequate open space for passive recreation and other outdoor living purposes and to offer diverse housing within walking distance of restaurants, stores and services.
         (c)   Planned business development. The planned business development provisions are established to provide opportunities to strengthen the economic viability and enhance the aesthetic qualities of the business districts through the promotion of larger scale (rather than parcel by parcel) developments of a unified design, which may include shared parking and other amenities. Such developments are intended to provide economic benefit to the community, property owners, and businesses, which benefits may be achieved by various means including by encouraging investment in the community and providing goods and services to support the overall welfare of the community.
   (B)   Design standards. The design standards and definitions set forth in § 156.002 and §§ 156.070 through 156.080 of the subdivision regulations shall be applicable to all planned residential developments, unless otherwise approved by the City Council.
