8-7-4: RESIDENTIAL DENSITY STANDARDS:
   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)
