1156.01 PRINCIPAL PERMITTED USES.
   (a)   Intent. The intent of the PD-R district regulations is to:
      (1)   Provide flexibility in architectural design, placement and clustering of buildings, use of open space, provision of traffic circulation facilities and parking, and related site and design considerations;
      (2)   Encourage the preservation and best use of existing landscape features through development sensitive to the natural features of the surrounding area;
      (3)   Promote efficient land use with smaller networks of utilities and streets;
      (4)   Encourage and preserve opportunities for energy efficient development;
         A.   Promote an attractive and safe living environment that is compatible with surrounding residential developments; and
         B.   Provide an alternate method for redeveloping older residential areas and to encourage infill development.
   (b)   Permitted Uses. Those uses specified as permitted principal uses, permitted accessory uses, and conditional uses in the "R-l," "R-2," "R-3," and/or "R-4" residential zoning districts, developed in a unified manner in accordance with the approved development plan
   (c)   Applicability. Housing shall be permitted as follows:
      (1)   For development of land of two (2) acres or more.
      (2)   For development of land less than two (2) acreswhere such development is more appropriate and more efficient than conventional development because of environmentally sensitive areas, existing natural features or scenic assets, the amount of land available for infill development, or the age of existing development in the vicinity.
   (d)   General Requirements. All PD-R developments shall meet the following criteria:
      (1)   Land uses. Any residential uses are permitted. Combinations of land uses may include single-family, multi-family, and group care facilities.
      (2)   Variations. Variations in the requirements of the underlying district may be permitted. However, setbacks required by the Ohio Basic Building Code, legislated by the State of Ohio, or the Ohio Residential Code For One-, Two-, and Three-Family Dwellings, whichever is applicable, shall be provided.
      (3)    Dwelling unit density. The dwelling unit density shall be calculated on the buildable acreage (gross acreage less public and/or private street right-of-way, flood plain, etc.) divided by the minimum lot size (square footage) for the allowed "R" Zoning District. Lot sizes can be less than the minimum designated in the "R" District provided the dwelling unit density of the buildable acreage does not exceed the density permitted in the "R" District. Density should be in accordance with Section 1161.02 (b) (1).
      (4)    Streets. Planned developments shall make provision for the extension of streets, if any.
      (5)   Storm water management. The planned development shall comply with the requirements for storm water management, including the provision of detention or retention basins. The developer shall submit a legally binding instrument setting forth the procedures to be followed in maintaining the areas and the means for financing maintenance costs. Generally, such costs shall be shared by all owners of property located within the planned development, with unpaid costs becoming a lien against individual properties.
      (6)    Open space. Except in a conventional subdivision, planned developments are encouraged to provide open space for flood control, agriculture, active or passive recreational purposes, etc., and to enhance the general character of the area. In the event the open space land is to be retained under private ownership, the developer shall submit a legally binding instrument setting forth the procedures to be followed in maintaining the areas and the means for financing maintenance costs as with storm water detention or retention basins in subsection (5) above.
      (7)   Dedication of land for public or common use. All proposed dedications of land for public or common use, including those to be dedicated for recreational use, shall be approved in writing by appropriate departments of the Village or County before the approval of the plan by the Village Council.
      (8)    Ownership. At the time of approval of a preliminary plan, the developer must submit evidence of ownership of the property to be developed or show evidence of a legally binding executed option agreement for purchasing all the property.
      (9)    Schedule of completion. A developer or agent of a planned development shall submit a signed statement generally describing the proposed development and setting forth an intended time schedule for the completion of various phases.
      (10)    Other requirements. Other conditions may be imposed as deemed necessary to fulfill the purpose and intent of this chapter. Such conditions may include but are not limited to planting screens, fencing, construction commencement and completion dates, lighting, operational controls, improved traffic circulation, highway access restrictions, yards, and parking requirements.
   (e)    Requirements for Areas less than Two (2) Acres. A PD-R plan for an area containing less than two (2) acres shall in addition to or in lieu of the requirements elsewhere above, meet the following requirements:
      (1)    The density and design of the PD-R shall be compatible in use, size and type of structure, relative amount of open space, traffic circulation, and general layout with adjoining land uses, and shall be integrated into the neighborhood. (See 1161.02(b)(1))
      (2)    Multi-family structures located adjacent to existing single-family dwellings shall be sited, landscaped, and screened by natural features and plant materials to harmoniously integrate the planned development with the surrounding neighborhood.
      (3)    The development shall not overburden existing streets and utilities.
      (4)    The development Plan as approved by the Developer shall not adversely affect views, light and air, property values as determined by a licensed/certified Professional and privacy of neighboring properties any more than would a conventional development.
