No site shall be considered as a planned residential development for townhouse, senior citizen or multifamily development unless it shall contain five or more acres of adjoining and contiguous land and shall contain sufficient access to an approved and improved public street, certified to be suitable or approved by the Joint Planning Board, unless such site qualifies as a planned residential development under the definition provided in §
142-87 of this Part
4. For the purpose of this Part
4, internal streets, roads to be dedicated and rights-of-way shall not be deemed to divide acreage of a planned development and shall be considered as part of the gross site area. Subdivision into lots or separate ownership of less than five acres, however, shall not be deemed prohibited provided that the planned residential development otherwise meets the criteria of this section. Subdivision and separate ownership of single-family detached dwellings on lot that comply with the lot width, lot size and road frontage requirements applicable in A Residence Districts shall also not be deemed prohibited, although less than five acres in size, provided that the criteria of this section are otherwise complied with.
All tracts, parcels or lots within a Planned
Residential Development Zone which do not qualify as a planned residential
development, and until preliminary site plan approval as a planned
residential development, shall be governed by the rules and regulations
of the applicable zoning in effect without reference to this Part
4.
The minimum distance between any two buildings
shall be not less than 1/3 the average height of the buildings involved
at their closest proximities, except that the Joint Planning Board,
on site plan review, may require a greater minimum distance, but not
more than the average height of the buildings involved at their closest
proximities or 12 feet, whichever is greater, where such greater distance
is determined by the Joint Planning Board to be necessary to provide
adequate access for the building or buildings.
The maximum height of buildings shall not exceed
two habitable stories, and the height thereof shall not in any event
exceed 35 feet, including roof mechanical equipment, measured at any
point of the adjacent finished grade at the building line.
The maximum area of the gross site which may
be covered by buildings, private parking areas, private driveways,
road surfaces and other impermeable surfaces, with the exception of
walkways and recreational facilities, shall not exceed 50% of the
gross site area.
Minimum dwelling unit floor area requirements
shall be as follows:
A. One-family dwelling: as required in the A Residence
District.
B. Senior citizen dwelling: 600 square feet.
C. Townhouse or multifamily dwelling, each dwelling unit:
(1)
Efficiency unit: 600 square feet.
(2)
