This chapter details the requirements for conventional developments. A special use permit for a planned unit development allows an innovative and imaginative design and provides that each case is considered individually.

Several types of planned unit developments are possible: cluster developments of single-family dwellings on reduced size lots with common open space; business developments of unified design and developments combining two (2) or more land uses into a coordinated whole. (Ord. 90-O-16, 7-3-1990)

The intent of the planned unit development is not to disregard this title, but to allow other approaches to fulfill the purposes and intents of this title. Requirements for parking and loading must be met in a planned unit development. The requirements of this title or other requirements of this code may be modified if adequate provisions are made to compensate for changes from the requirements of this title. With this in mind, the following design standards must be a part of each planned unit development:

   A.   Preservation Of Landscape: The landscape shall be preserved in its natural state insofar as possible by minimizing tree and soil removal. Any grade changes shall be in keeping with the general appearance of neighboring developed areas.

   B.   Relation Of Proposed Building To Environment: Proposed structures shall relate harmoniously to the terrain and to existing buildings in the vicinity. This may include the enclosure of space in conjunction with other existing or proposed buildings, creation of focal points with respect to avenues of approach, terrain features or other buildings or other visual relationships.

The inventory and analysis phase during the design process should consider the property and surrounding area for a distance of not less than one thousand feet (1,000') in terms of topography, soils and geology, waterways, wetlands, wildlife, drainage, vegetation, adjacent land uses and zoning, utilities, roadways, trails and other information necessary to prepare a PUD that meets the high standards of the village.

   C.   Drives, Parking And Circulation: Attention shall be given to the location and number of access points to the public streets of both pedestrian and vehicular circulation.

   D.   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 storm drainage.

   E.   Utility Services: Electric and telephone lines shall be underground. All planned unit developments must specify both water source and method of disposal of sanitary sewage. (Ord. 2011-O-24, 11-1-2011)

A planned unit development may be located in any district zoned for a use which is a component of that planned unit development. No planned unit development may be located in a district which is not zoned for one component of that planned unit development. (Ord. 90-O-16, 7-3-1990)

   A.   Maximum Number Of Dwelling Units: Within a residential planned unit development or in the residential component of a multi-use planned unit development, the maximum number of dwelling units shall be determined by the area of the minimum lot size permitted for the zoning classification of the area in which the proposed development is located. In the event that the subject property is classified into two (2) or more zoning classifications, the density shall be determined by calculating separately the number of units which would be allowed on that land area in each zoning district and adding them together. If the density calculation results in a fraction number, the permitted number of dwelling units shall be the same as the lower whole number.

   B.   Lot Yield: In calculating lot yield, each lot shall contain a minimum area of thirty three thousand (33,000) square feet, excluding areas where slopes are in excess of fifteen percent (15%), floodplains, land incapable of meeting percolation requirements, land formerly used for landfill operations or hazardous industrial use, fault areas, stream corridors, estuaries, wetlands, marshes, bogs, fens, lakes, ponds and other bodies of water.

   C.   Common Open Space: The space resulting from the reduced size of the individual lots in a planned unit development shall be common open space for the enjoyment or benefit of all residents of the development or by mutual agreement between the Village and the developer, such area may be dedicated as public open space. Primary (abutting) access from such common open space to each building site need not be provided; however, convenient access through permanent easement must be provided and perpetually guaranteed to all residents not granted primary access. Open space land shall not be utilized for future residential building sites. (Ord. 90-O-16, 7-3-1990)

The floor area ratio of a nonresidential planned unit development or of the nonresidential component of a multi-use planned unit development shall not exceed the lowest floor area ratio of the nonresidential zoning district in which any of the nonresidential uses could be located as a permitted use. (Ord. 90-O-16, 7-3-1990)

   A.   Application: An applicant for a special use permit for a planned unit development or any amendment thereto shall file an application with the Village Clerk which includes any proposed articles of incorporation and declaration of covenants and restrictions. The planned unit development plan shall also be submitted for review. This plan shall include a statement of purpose of the PUD and the standards which shall be met by the PUD, with reference to both this Title and Title 9 of this Code.

   B.   Comprehensive Site Development Plan: In addition, a comprehensive site development plan shall be submitted first in the form of a preliminary plat including the arrangement and location of buildings, uses permitted, open space and landscaped areas, pedestrian walkway areas, parking and loading spaces and facilities and other special features. This is to be followed once the plat has been approved by a detailed landscaping plan showing the spacing, sizes and specific type of landscaping material to be used. Developers are encouraged to follow the sketch plan, preliminary plat, and final plat procedures contained in Chapter 4 of Title 9.

   C.   Architectural Elevations And Perspective Drawings: Architectural elevations and perspective drawings of all proposed structures and improvements should also be submitted, except that in the case of a totally residential planned unit development with individual dwellings to be custom built to the buyer's specifications, only general elevations and perspective drawings need be submitted.

   D.   Fiscal Impact Study: A fiscal impact study prepared by the developer shall be submitted to the Village. The fiscal impact study shall list the revenues that Village will receive from the PUD if approved and the costs to the Village of providing Municipal services.

   E.   Traffic Impact Study: A traffic impact study prepared by the developer shall be submitted to the Village showing the estimated changes in traffic volumes and congestion on nearby collector distributor and arterial streets as a result of the proposed PUD.

   F.   Development Schedule: A development schedule should be submitted indicating the approximate date for the beginning of construction, the stages, if any, in which the project will be built and the approximate dates when construction of each stage can be expected to begin, the anticipated rate of development and the approximate date when development of each of the stages will be completed.

   G.   Surface Water Drainage Plan: A general surface water drainage plan shall be submitted which shall indicate the existing contours (at one foot intervals), proposed contours and method of controlling storm water drainage.

   H.   Water And Sewer Plan: A water and sewer plan shall be submitted indicating the location of wells and septic tanks or other sewage treatment facilities, together with the estimated usage in number of gallons of each.

   I.   Financial Assurances: A statement of proposed financing and acceptable financial assurances must be submitted to guarantee that once any stage of development is started, it will be completed. (Ord. 90-O-16, 7-3-1990)
