§ 155.146 PUD PLANNED UNIT DEVELOPMENT OVERLAY DISTRICT.
   (A)   Purpose.
      (1)   The purpose of planned unit development regulations is to allow more creative and imaginative design of land development than may be possible under district zoning regulations.
         (a)   Planned unit developments are intended to allow substantial flexibility in planning and design while maintaining consistency with the general provisions of this chapter and of the city's comprehensive plan.
         (b)   This flexibility often accrues in the form of relief from compliance with conventional Zoning Ordinance site and design requirements.
         (c)   Ideally, this flexibility results in a development that is better planned and makes more efficient use of resources than one produced in accordance with typical Zoning Ordinance standards.
      (2)   Approval of a planned unit development is intended to:
         (a)   Promote innovative and creative design of residential and nonresidential areas;
         (b)   Promote efficient use of land by facilitating a more economic arrangement of buildings, infrastructure, circulation systems, land use and facilities;
         (c)   Encourage high standards in the layout, design and construction of residential and nonresidential development and promote opportunities for varied housing types;
         (d)   Conserve, protect and enhance the natural environment through flexibility of design and development within a PUD, and preserve environmentally sensitive lands;
         (e)   Allow a diversification of uses, structures and open space in a manner compatible with both the surrounding, existing and approved development of land surrounding and abutting the PUD site;
         (f)   Provide more useable and suitably located open space and recreation facilities, as well as other public and common facilities than would otherwise be provided under conventional land development planning practices;
         (g)   Achieve harmonious building and site designs; and
         (h)   To create a method for the permanent preservation of historic buildings and/or landmarks.
   (B)   Designation.
      (1)   Criteria for designation. A designation for a Planned Unit Development Overlay District may be made if:
         (a)   The PUD Overlay District project would result in a greater benefit to the city than would development under the base zoning district regulations;
         (b)   The site of the proposed PUD Overlay District contains at least two acres of contiguous land, unless Council finds that the property of less than two acres is suitable by virtue of its unique historical character, topography or other natural features or unique design layout of proposed subdivision; and
         (c)   The PUD Overlay District project satisfies all other provisions of this subchapter and is consistent with the city's comprehensive plan.
      (2)   Process for designation. The initiation, application and procedure to establish a PUD Overlay District shall be in accordance with division (A) above. Additionally, the master development plan must include:
         (a)   The existing and proposed use of the structure;
         (b)   Any planned rehabilitation by the property owner; and
         (c)   The nature and degree of endangerment to the structure.
      (3)   Removing a designation. A designation for a PUD Overlay District may be removed in the same manner and by the same process by which it was enacted.
   (C)   Property development standards.
      (1)   Lot. The minimum lot area, width, frontage and yard requirements for single-family residences may be altered as approved by City Council.
      (2)   Streets. Minimum street widths or alleys proposed within a PUD Overlay District shall be flexible in order to promote innovative design.
      (3)   Off-street parking. A minimum of two off street parking spaces shall be provided for each single-family unit.
         (a)   The required off-street parking spaces must be located on the lot of the single-family unit or be provided elsewhere within the proposed development.
         (b)   The single-family dwelling unit garage does not count toward satisfying this requirement.
         (c)   No portion of a street may be used in calculating the required off-street parking spaces. All nonresidential parking shall comply with city ordinances and regulations.
      (4)   Building height. Height limitations shall be the same as imposed in this chapter for the underlying zoning district.
      (5)   Open space. At least 30% of the open space required in herein shall be converted to common areas used for recreation or parks.
      (6)   Landscaping. Landscaping shall be provided for residential and nonresidential developments. A minimum of two trees and eight shrubs shall be provided for each single-family residential unit on each single-family residential lot. Fifty percent of the required trees may be located in an open space as defined herein. The specific placement, forward of the rear building line, shall be left to the discretion of the developer. Whenever practicable, the preservation of existing trees is encouraged.
      (7)   Buffering and screening. Open space buffers and screening shall be required to separate land uses within ths PUD Overlay District. No parking lot, structures or equipment pads shall be placed in an open space buffer. The minimum size of an open space buffer shall be 20 feet measured from the exterior property line that is adjacent to the single-family or duplex use. Screening shall be provided along the property line adjacent to the single-family or duplex use.
      (8)   Engineering and construction standards. Engineering and construction standards shall be the same as imposed in the International Building Code.
