168.05 SPECIAL PURPOSE AND OVERLAY DISTRICTS.
   1.   Defined.
      A.   ID Interim Development District. The ID District is intended to preserve existing agriculture and other non-intensive uses to prevent premature development and non-orderly encroachment of higher intensity urban uses, and to help guide urban growth into suitable areas.
      B.   P Public Use District. The P District is intended to provide space for public safety, administration, recreational, and community facilities.
      C.   PO Professional Office Overlay District. The PO District is intended to be limited in use and will only be used for those special situations where the establishment of this district will not alter the essential character of any residential district in which it could be placed, and will, in addition, require that any land owner desiring to establish this district shall enter into a written agreement with the City to abide by such terms and conditions as required by the City.
      D.   PAD Planned Area Development Overlay District. The PAD District is intended to encourage innovation and flexibility in planning the development of land so development is compatible with the site’s physical and environmental characteristics. This district allows for flexibility in district requirements. The Planned Area Development District provides an opportunity for the development of a mixture of uses and housing types in a coordinated manner. The intent of the underlying district shall guide the development. It is incumbent upon the person proposing the PAD to justify the project, and any variations from the underlying zone district.

      B.   PAD Planned Area Development Overlay District
         (1)   General. Planned area developments may be allowed by Council approval in any zoning district. No such planned area development permit shall be granted unless such development either meets the use limitations of the zoning district in which it is located and the density and other limitations of such district, except as such requirements may be lawfully modified as provided by this code. Compliance with the regulations of this section in no way excuses the developer from the applicable requirements of a subdivision ordinance, except as modifications thereof are specifically authorized in the approval of the application for the planned area development.
         (2)   Conditions.
            (a)   Area. No planned area development shall have area less than that approved by the Council as adequate for the proposed development.
            (b)   Uses. A planned area development that will contain uses not permitted in the zoning district in which it is to be located will require a change of zoning and shall be accompanied by an application for a zoning amendment, except that any residential use shall be considered a permitted use and shall be governed by density, design and other requirements of the planned area development permit.
            (c)   Ownership. The development shall be in single or corporate ownership at the time of application, or the subject of an application filed jointly by all owners of the property.
            (d)   Design. The Commission and Council shall require such arrangements of structures and open spaces within the site development plan as necessary to ensure that adjacent properties will not be adversely affected.
               (i)   Density. Density of land use shall in no case be more than 25 percent higher than allowed in the zoning district, except not more than 10 percent higher in residential districts.
               (ii)   Arrangement. Where feasible, the least height and density of buildings and uses shall be arranged around the boundaries of the development.
               (iii)   Specific Regulations. Lot area, width, yard, height, density, and coverage regulations shall be determined by approval of the preliminary site plan, which shall accompany the application.
            (e)   Open Spaces. Preservation, maintenance, and ownership of required open spaces within the development shall be accomplished by either:
               (i)   Dedication of land as a public park or parkway system, or
               (ii)   Granting to the jurisdiction a permanent, open space easement on and over the said private open space to guarantee that the open space remain perpetually in recreational use, with ownership and maintenance being the responsibility of an owners’ association established with articles of association and bylaws which are satisfactory to the Council.

            (g)   Signs. The size, location, design, and nature of signs, if any, and the intensity and direction of floodlighting shall be detailed in the application.
            (h)   Exterior Lighting. The size, material type, location, and intensity of all exterior lighting shall be detailed in the application.
            (i)   Desirability. The proposed use of the particular location shall be shown, as necessary or desirable, to provide a service or facility which will contribute to the general well-being of the surrounding area. It shall also be shown that under the circumstances of the particular case, the proposed use will not be detrimental to the health, safety, or general welfare of persons residing in the vicinity of the planned area development.
         (3)   Commission and Council Determination. In carrying out the intent of this section, the Commission and Council shall consider the following principles:
            (a)   It is the intent of this section that site and building plans for a planned area development shall be prepared by a designer or team of designers having professional competence in urban planning as proposed in the application. The Commission and Council may require the applicant to engage such expertise as a qualified designer or designer team.
            (b)   The Council may approve or disapprove an application for a planned area development. In approval, the Council may attach such conditions as it may deem necessary to secure compliance with the purpose set forth in this chapter.
         (4)   Commission and Council Action.
            (a)   Approval. In order that it may approve a planned area development, the Council shall have authority to require that the following conditions (among others it deems appropriate) be met by the applicant:
               (i)   The proponents of the planned area development shall demonstrate to the satisfaction of the Council that they are financially able to carry out the proposed project.
               (ii)   The proponents intend to start construction within one year of either approval of the project or of any necessary zoning district change, and intend to complete said construction, or approved stages thereof, within four years from the date construction begins.
            (b)   Limitations on Application.

               (ii)   Amendment to approved plans and specifications to a planned area development shall be obtained only by following procedures here outlined for first approval.
               (iii)   The Code Official shall not issue any permit for any proposed building, structure or use within the project unless such building, structure, or use is in accordance with the approved development plan and any conditions imposed in conjunction with its approval.
