§ 156.145  ADDITIONAL STANDARDS FOR PLANNED DEVELOPMENTS.
   (A)   Intent.  A planned development is intended to encourage innovative designs in the development of land.
   (B)   Additional standards and criteria for planned developments. In addition to the standards and criteria set forth in § 156.142(E)(6), planned developments shall comply with the following standards and criteria.
      (1)   Modifications from district regulations. Modifications from district regulations shall adhere to § 156.143, Modification of District Regulations for Planned Developments, and comply with the following standards.
         (a)   Lowland yards, as required by § 156.073 of the zoning code, shall not be varied.
         (b)   Lot coverage can exceed the amount required by § 156.073, up to 5%, provided the Plan and Zoning Commission and the City Council find that the development has incorporated environmentally-sensitive design and energy-efficient practices that will mitigate the increased coverage.
      (2)   Design standards.
         (a)   Design guidelines.
            1.    Design guidelines, as contained in Appendix B, shall apply to the planned development, unless an applicant chooses to establish their own set of guidelines as part of the planned development, establishing more creative and site-specific standards.
            2.   When guidelines are created for a planned development, the city's guidelines will be used as a baseline for review, and similar or better standards are expected.
            3.   The Plan and Zoning Commission will make recommendation on, and the City Council may approve, such guidelines.
            4.   Planned developments following the city's design guidelines may deviate from the recommendations, provided it is determined that the deviation is justifiable and does not alter the intent of the guidelines.
         (b)   Exterior building materials.  Deviations from the standards contained in Appendix A are permitted if justified by the applicant. Structures or buildings that demonstrate exceptional architectural merit and/or an intention to reflect the historic character of the city may deviate from the provisions of Appendix A, Exterior Building Materials, to allow the use of different materials, or to allow the use of a different percentage or proportion of the materials otherwise required in the exterior finish of a structure or building.
      (3)   Standards for open space.  Open space provided in a planned development may be as proposed by the applicant, required under standards of the city code, or as a condition of city approval of the planned development. No open space may be delineated or accepted under the provisions of this subchapter unless it is in keeping with the following standards.
         (a)   All land shown on the final development plan as planned open space must either be:
            1.   Conveyed to a public body, if the public body agrees to accept conveyance, to maintain the planned open space and any buildings, structures or improvements that have been placed in it; or
            2.   Conveyed to a homeowners' association or similar organization organized for the purpose, among others, of owning and maintaining common buildings, areas and land within the planned development. The planned open space must be conveyed, subject to covenants to be approved by the city, which restrict the planned open space to the uses specified on the final development plan, and which provide for the maintenance of the planned open space in a manner that assures its continuing use for its intended purpose.
         (b)   No portion of a planned development shall be conveyed or dedicated by a developer, or any other person, to any public body or a homeowners' association, unless the Plan and Zoning Commission has determined that the character and quality of the tract to be conveyed make it suitable for the purposes for which it is intended. When making its determination, the Plan and Zoning Commission shall consider the size and character of the dwellings to be constructed within the planned development, the topography and existing trees, ground cover, and other natural features; the manner in which the open area is to be improved and maintained for recreational or amenity purposes; and the existence of public parks or other public recreational facilities in the vicinity.
      (4)   Signs. The city may require, as a condition of the special use permit, more restrictive sign regulations than otherwise permitted by the city code.
      (5)   Additional standards for residential planned developments. Densities recommended by the city comprehensive plan need not be strictly adhered to, provided the development will not negatively impact neighboring development, is sufficiently buffered from adjacent properties, and closely applies the city’s design principles included in the comprehensive plan.
      (6)   Additional standards for planned developments with commercial uses.  For commercial uses located within a planned development, regulations other than those of the underlying district may be applied, subject to the following restrictions.
         (a)   Structures and uses shall be located, designed and operated so as to have direct pedestrian access to residential areas, if applicable.
         (b)   Layout of parking and loading areas, service areas, entrances, exits, yards, courts, landscaping and the control of signs, lighting, noise and other potentially adverse influences shall be mitigated to avoid impact on the residential areas within or adjoining the development.
         (c)   The structures and uses, by reason of their location, construction, manner of timing of operation, shall not have adverse effects on residential uses within or adjoining the development, or create traffic congestion or hazards to vehicular or pedestrian traffic.
         (d)   Design standards shall be as set forth in division (B)(2) above.
