§ 154.161 PLANNED UNIT DEVELOPMENT.
   (A)   Intent and purpose. The planned unit development (PUD) provisions are intended to encourage more efficient use of land, public services and greater amenity by allowing, under certain circumstances, a more flexible means of land development or redevelopment than is otherwise afforded through the strict enforcement of the zoning requirements of certain districts through lot-by-lot development. Although planned unit developments may appear to deviate in certain aspects from a literal interpretation of the zoning and subdivision ordinances, the PUD and its accompanying guidelines are intended to allow flexibility in design in order to promote developments which will be an asset to the city by equaling or surpassing the quality of developments resulting from the application of more conventional zoning regulations. A PUD may be used as an overlay district over any based zoning district or combination of zoning districts.
   (B)   Establishment. A planned unit development shall be established by rezoning to a newly created, numbered Planned Unit Development District that outlines the uses, dimensions and design standards of the new PUD zoning district following the procedures set forth in § 154.070.
   (C)   Minimum size. Planned unit developments shall be on a tract of land not less than one acre.
   (D)   Uses. Permitted uses shall generally be consistent with the permitted or conditional uses of the underlying base district. However, a PUD district can request alternative uses to the permitted uses of the underlying base district, subject to the approval by the City Council as part of the establishment of the PUD.
   (E)   Density. Density of development will be reviewed based on the following criteria:
      (1)   Effect on adjacent properties;
      (2)   Adequacy of public and private services and infrastructure;
      (3)   Overall design;
      (4)   Scale and massing of structures;
      (5)   Building elevations and setbacks;
      (6)   Landscaping, screening and buffering;
      (7)   Open space provision and design; and
      (8)   Retention of natural, cultural and historic resources.
   (F)   Dimensional and design standards. The following provisions shall be addressed as part of the PUD. When it is intended that regulations vary from the underlying district, the applicant shall propose them as part of the PUD application process:
      (1)   PUD perimeter. A PUD shall be designed to complement existing adjacent uses and infrastructure.
      (2)   Lot area. Lot area may vary from the underlying base district standard in a PUD provided the developer has demonstrated that the proposed design and layout meets the provisions of this chapter.
      (3)   Yard setbacks. Setbacks may vary from underlying base district standards in a PUD provided the developer has demonstrated that the proposed design and layout meets the provisions of this chapter. Perimeter setbacks shall be consistent with the setbacks of adjacent zoning districts.
      (4)   Building height. Building height may vary from the underlying base district standard. The city may request cross sections, elevations and other information from the developer in order to determine if the structure height meets the provisions of this chapter.
      (5)   Environmental design. A PUD shall be designed to preserve existing vegetation and topography where practical and shall be consistent with the goals and objectives of the comprehensive plan.
      (6)   Common open space. A PUD shall include common open space that is functional, improves appearance and aesthetics, is accessible and where possible adds to existing common or public open space systems.
         (a)   Common open space shall not include:
            1.   Setback areas;
            2.   Street right-of-way;
            3.   Parking areas and driveways;
            4.   Building sites;
            5.   Private/internal walkways and trails; or
            6.   Inaccessible stormwater ponds.
         (b)   Common open space may include land dedicated for public parks, trails or pathways.
         (c)   All structures or facilities proposed as part of common open space systems shall be completed as part of the required improvements or infrastructure of the proposed PUD.
         (d)   A PUD shall provide the following minimum amount of common open space based on the land use type that comprises more than 50% of the land use for the development:
            1.   Residential shall provide at least 30% of common open space;
            2.   Commercial shall provide at least 15% of common open space; and
            3.   Industrial shall provide at least ten percent of common open space.
      (7)   Architecture. A PUD shall include and incorporate architectural planning by the developer and implementation provisions for controlling the architecture by protective covenants, design overlay districts enforced by the city or other legal methods. Overall architectural design shall be generally compatible with the characteristics of the surrounding developments.
      (8)   Parking. Parking ratios may deviate from the off-street parking space standards. Where alternative parking ratios are not stated in the PUD application, they shall conform to the § 154.295 parking standards.
      (9)   Streets, utilities and drainage. All publicly dedicated streets, utilities and stormwater facilities shall be designed in accordance with city ordinances and policies. The city may consider flexible standards for streets if the developer has demonstrated that the proposed design and layout warrants varying standards and the design meets the provisions of this Title.
      (10)   Traffic calming design.
         (a)   Traffic calming measures and good street design shall be considered in all PUDs.
         (b)    Traffic calming examples.
      (11)   Circulation/access.
         (a)   Vehicular access to lots adjoining an arterial as defined by the functional classification system shall be designed by way of a frontage road, service road or local street.
         (b)   Streets in a PUD shall be designed to promote a grid network of streets, minimizing dead ends and cul-de-sacs and connecting to adjoining developments where streets have been "stubbed in" for the purpose of continuation.
         (c)   A PUD shall include provisions for pedestrians, bicycles and transit.
   (G)   Landscaping. A landscape and screening plan shall be included in the PUD submittal to the city including street tree provisions, screening, parking lot landscaping where applicable and the preservation of mature, healthy hardwood trees where applicable.
   (H)   Signs. A sign plan shall be included in the PUD submittal to the city. Signage shall generally conform to §§ 154.340 through 154.351, Sign Regulations. Freestanding pylon type signs shall consolidate tenants or uses in predetermined locations, minimizing the number of freestanding signs where possible.
