A.   Planned Developments Are Not Permitted As Of Right: Planned developments shall be approved by the village only in direct response to the accrual of tangible public benefits from the planned development to the village and its residents, along with the neighborhood and area in which the planned development is proposed. These benefits shall include, without limitation, exceptional amenities, landscape features, architectural or site design, or the conservation of special manmade or natural features of the site, all as more specifically set forth in the standards set forth in subsection B of this section.
   B.   General Design Standards: No application for a planned development shall be approved by the corporate authorities unless the proposed planned development satisfies the standards set forth in this subsection B and subsection C of this section. All of these standards shall not be regarded as inflexible, but shall be used as a framework by the village to test the quality of the amenities, benefits to the community, and design and desirability of the proposal.
      1.   Commercial Areas Revitalization Master Plan: The planned development shall not be inconsistent with the planning policies, goals, objectives, and provisions of the village's commercial areas revitalization master plan. A planned development must also not be inconsistent with the intent and spirit of the village of Oak Brook comprehensive plan.
      2.   Public Welfare: The planned development shall be designed, located, and proposed to be operated and maintained so that it will not impair an adequate supply of light and air to adjacent property and will not substantially increase the danger of fire or otherwise endanger the public health, safety and welfare.
      3.   Impact On Other Property: The planned development shall not be unnecessarily injurious to the use or enjoyment of other property in the neighborhood for the purposes permitted pursuant to the applicable zoning district, shall not prevent the normal and orderly development and improvement of surrounding properties for permitted uses, shall not be inconsistent with the community character of the neighborhood, shall not alter the essential character of the neighborhood, and shall not substantially diminish or impair property values within the neighborhood, or be incompatible with other property in the immediate vicinity. The uses permitted in a planned development must be of a type and so located so as to exercise no undue detrimental influence upon surrounding properties. The planned development must also address compliance with the village's noise, lighting, and other performance standards.
      4.   Impact On Public Facilities And Resources: The planned development shall be designed so that adequate utilities, road access, drainage, and other necessary facilities will be provided to serve the development. The planned development shall include such impact donations as may be reasonably determined by the corporate authorities. The required impact donations, including, without limitation, obligations under the village's subdivision regulations, shall be calculated in reasonable proportion to the impact of the planned development on public facilities and infrastructure to the extent permitted by law.
      5.   Archaeological, Historical Or Cultural Impact: The planned development shall not substantially and adversely affect a known archaeological, historical, or cultural resource located on or off of the parcel proposed for development.
      6.   Parking And Traffic: The planned development shall have or make adequate provision to provide ingress and egress to the proposed use in a manner that minimizes traffic congestion in the public streets, provides appropriate cross access to adjacent properties and parking areas, and provides adequate access for emergency vehicles.
      7.   Adequate Buffering: The planned development shall have adequate landscaping, public open space, and other buffering features to protect uses within the development and surrounding properties.
      8.   Signage: Signage on the site of the planned development shall generally be in conformity with the village's sign regulations (chapter 11 of this title), except as may otherwise be specifically provided in the ordinance approving a planned development.
      9.   Ownership/Control Area: The site of the planned development must be under ownership and/or unified control of the applicant.
      10.   Need: A clear showing of need for the planned development must be made by means of an economic feasibility, land utilization and marketing study.
      11.   Compliance With Subdivision Regulations And Plat Act: All planned developments, whether or not they are by definition subject to the village's subdivision regulations or the Illinois plat act, shall comply with all standards, regulations and procedures of the village's subdivision regulations and the plat act except as is expressly provided otherwise in this chapter, or as otherwise provided by the corporate authorities pursuant to the ordinance approving the planned development, or the applicable sections of the village's subdivision regulations.
      12.   Covenants And Restrictions To Be Enforceable By Village: All covenants, deed restrictions, easements, and similar restrictions to be recorded in connection with the planned development shall provide that they may not be modified, removed, or released without the express consent of the corporate authorities and that they may be enforced by the village as well as by future landowners within the proposed development.
      13.   Security And Site Control: The planned development shall include the plans necessary to describe, establish, and maintain appropriate property and building security and site control measures for the planned development and the property on which the planned development is located. These plans shall also include measures to prevent adverse impacts on neighboring properties.
   C.   Additional Standards: In addition to the standards required in subsection B of this section, the following standards shall be considered in reviewing all proposed and amended planned developments, particularly with regard to elements of planned development proposals that do not satisfy the otherwise applicable provisions of the underlying zoning and subdivision regulations:
      1.   Integrated Design: A planned development shall be laid out and developed as a unit in accordance with an integrated overall design. This design shall provide for safe, efficient, convenient and harmonious grouping of structures, uses and facilities, and for appropriate relation of space inside and outside buildings to intended uses and structural features.
      2.   Beneficial Common Open Space: Any common open space in the planned development shall be integrated into the overall design. These open spaces shall have a direct functional or visual relationship to the main building(s) and shall not be of isolated or leftover character. The following would not be considered usable common open space:
         a.   Areas reserved for the exclusive use or benefit of an individual tenant or owner.
         b.   Dedicated streets, alleys and other public rights of way.
         c.   Vehicular drives, parking, loading and storage areas.
         d.   Irregular or unusable narrow strips of land.
      3.   Functional And Mechanical Features: Exposed storage areas, trash and garbage retainers, exposed machinery installations, service areas, truck loading areas, utility buildings and structures, and similar accessory areas and structures shall be accounted for in the design of the planned development and made as unobtrusive as possible. These features shall be subject to such setbacks, special planting or other screening methods as shall reasonably be required to prevent their being incongruous with the existing or contemplated environment and the surrounding properties.
      4.   Visual And Acoustical Privacy: The planned development shall provide reasonable visual, and acoustical privacy. Fences, insulations, walks, barriers and landscaping shall be used as appropriate for the protection and aesthetic enhancement of property and the privacy of its occupants, screening of objectionable view or uses, and reduction of noises.
      5.   Energy Efficient Design: A planned development shall be designed with consideration given to various methods of site design and building location, architectural design of individual structures, and landscaping design capable of reducing energy consumption within the planned development. The applicant will be encouraged, to the extent feasible, to obtain leadership in energy and environmental design ("LEED") certification for the project. A planned development applicant may also undertake the following:
         a.   Having at least one member of the applicant's project team be a "LEED accredited professional" - a person who has received the LEED accredited professional designation from the United States green building council ("USGBC"), the Green Building Certification Institute, or another entity authorized by the USGBC to grant that designation.
         b.   Having its application materials include a "LEED checklist" developed by the U.S. green building council indicating the credits pursued and total points anticipated for a project under the most appropriate LEED rating system, in consultation with the director of community development.
      6.   Drives, Parking And Circulation: Principal vehicular access shall be from dedicated public streets, and access points shall be designed to encourage smooth traffic flow with controlled turning movements and minimum hazards to vehicular or pedestrian traffic. With respect to vehicular and pedestrian circulation, including walkways, interior drives and parking, special attention shall be given to location and number of access points to the public streets, width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic, adequate provision for service by emergency vehicles, and arrangement of parking areas that are safe and convenient, and insofar as feasible, do not detract from the design of proposed buildings and structures and the neighboring properties. To the extent practical, planned developments shall provide connections to and from existing bike and walking paths so as to ensure a continuous route without gaps or disconnections.
      7.   Surface Water Drainage: Special attention shall be given to proper site surface drainage so that removal of surface waters will not adversely affect neighboring properties or the public storm drainage system. Surface water in all paved areas shall be collected at intervals so that it will not obstruct the flow of vehicular or pedestrian traffic. (Ord. G-890, 7-14-2009)
