In addition to the standards generally applicable to special uses, as provided in Article herein, no Planned Unit Development shall be approved unless the Plan Commission shall also find:
A. That said Planned Unit Development conforms with the intent and specific proposals of the Comprehensive Plan of the Village.
B. That the Planned Unit Development will be on a tract of land under common ownership or control and furthermore, any residential development shall not be considered for a special use in the nature of a Planned Unit Development unless it is located on a tract of land of ten (10) or more contiguous acres. In the O/R or R-1 zoning districts no development shall be considered for a special use in the nature of a Planned Unit Development unless it is located on a tract of land of 300,000 square feet or more contiguous area.
1. Such common ownership or control shall extend to all common open space, landscaping, exterior maintenance and all other exterior common area aspects of the development for a period of not less than twenty (20) years.
2. Said common ownership or control shall extend to all portions of the Planned Unit Development for a period of not less than eighteen (18) months following the completion of all public improvements, common area improvements, and the developer's relinquishing its control of any and all owners associations.
3. Common ownership or control as required herein shall mean unity of ownership or legal authority to act on behalf of all owners which shall be evidenced by deed, contract, management agreement or other written guarantee.
C. That the uses permitted in the Planned Unit Development shall conform to those in the zoning district within which the real property which is the subject of the Planned Unit Development is located and shall be compatible to each other and with existing land use in the surrounding area. Uses shall be deemed compatible if they are so designed, located, and proposed to be operated so that the public health, safety and welfare will be protected and such uses will not cause appreciable injury or damage to other property in the area in which it is located.
D. That the Planned Unit Development will be responsive to a demonstrated need within the community.
E. That the maximum height permitted in the Planned Unit Development, exclusive of steeples, belfries, spires, chimneys, smoke stacks, cooling towers, elevator bulkheads, parapet walls, and building equipment penthouses shall not exceed the maximum height permitted for the zoning district in which the development is located.
1. Provided such buildings do not exceed thirty (30) feet in height, the minimum horizontal distance between buildings (including their appurtenances) of one story, two stories, three stories, or combinations thereof, shall not be less than fifteen (15) feet.
2. In the case of buildings exceeding thirty (30) feet in height, the space between buildings shall be equal to the height of the tallest building from which the measurement is taken.
F. If granted, the principal use of the subject property shall be the Planned Unit Development. Accordingly, the only required yards shall be adjacent to the periphery of the Planned Unit Development and shall be at least equal in width or depth to the greater of the required yard for real property adjacent to the Planned Unit Development or a distance not less than the height of the closest building to such lot line. However, in the event such Planned Unit Development is located adjacent to real estate owned by the Illinois Toll Highway Authority, the yard adjacent to such Toll Highway Authority real estate shall be fifty (50) feet. No other yards are required.
G. That, in the case of a residential development, residential density of the Planned Unit Development shall not exceed in number of dwelling units the maximum number of lots that could be achieved through a conventional subdivision of the site as demonstrated by the subdivision sketch plan. It is understood that whenever the development is located in more than one zoning district, the number of allowable dwelling units must be separately calculated for each portion of the development that is in a separate zoning district. Thereafter the combined total of all dwelling units so calculated as allowable may be constructed and distributed within the entire Planned Unit Development without concern for the respective zoning districts within which the Planned Unit Development is located, provided there is compliance with building locations shown upon the site plan approved for such Planned Unit Development.
H. That the Planned Unit Development shall include a traffic plan which will provide ingress and egress which is designed to minimize traffic congestion in the public streets outside the Planned Unit Development and facilitate the free flow of traffic, both vehicular and pedestrian, within the Planned Unit Development. The streets and other traffic thoroughfares, public or private, provided in such Planned Unit Development shall conform with at least the minimum requirements for streets and public ways of the ordinances of the Village of Mettawa.
