§ 156.155  DISTRICT INTENT; PERMITTED USES; MISCELLANEOUS STANDARDS.
   (A)   District intent.
      (1)   The purposes of these regulations are to provide greater design flexibility in the development of land when consistent with the Comprehensive Plan and intent of this chapter and Ch. 155 of this code of ordinances. The use of planned development zoning classifications shall be encouraged when the use of such regulations promotes a harmonious variety of uses, and/or provides for an economy of shared services and facilities, and/or are compatible with surrounding areas and/or foster the creation of attractive, healthful, efficient and stable environments for living, shopping or working.
      (2)   The planned development regulations and procedures may apply to the development of existing developed lands, or vacant lands. Further, they generally only apply to large tracts of land.
      (3)   Planned development regulations are intended to encourage innovations in land development techniques so that the growing demands of the community may be met with greater flexibility, variety in type, design and layout of sites and buildings. Also, planned development projects should also encourage a more efficient use of land so that resulting economies may accrue to the benefit of the community at large. Examples of this concept would include the preservation of existing trees or wetlands, and the inclusion of recreation areas within new subdivisions.
   (B)   Permitted uses.
      (1)   All uses are subject to the discretion and approval of the Plan Commission. No uses are granted by right.
      (2)   In general, the uses that will be allowed in a planned development are: uses designated as permitted uses or special exceptions in the zoning district prior to being changed to a Planned Development District. For example if the previous zoning was R2 and the proposed Planned Development District would be PD-R2, the permitted uses and special exceptions in the R2 District would generally be appropriate.
      (3)   All other land uses will be reviewed and considered carefully by the Plan Commission. Mixed uses will be considered and are encouraged when appropriate. All land uses proposed in a PD must be non-conflicting and in the spirit of the previous zoning district and surrounding land uses and zoning districts.
   (C)   Miscellaneous standards.
      (1)   Minimum land area: 20 acres to qualify for any PD;
      (2)   Minimum overall lot frontage: 300 feet on a single public street with access from said public street;
      (3)   Maximum lot coverage: square feet of all primary and secondary structures, and impervious surface cannot exceed 65% of the lot area;
      (4)   Minimum floor area: based on zoning district prior to rezoning to a PD District;
      (5)   Maximum structure height:
         (a)   Forty feet for the primary structure; and
         (b)   Twenty feet for accessory structures.
      (6)   Minimum open space:
         (a)   Thirty percent for residential based planned developments; and
         (b)   Fifteen percent for commercial based planned developments.
