§ 81-f. Planned unit development zoning districts. A city legislative
body, except in a city having a population of more than one million
persons, is hereby authorized to enact, as part of its zoning local law
or ordinance, procedures and requirements for the establishment and
mapping of planned unit development zoning districts. Planned unit
development district regulations are intended to provide for
residential, commercial, industrial or other land uses, or a mix
thereof, in which economies of scale, creative architectural or planning
concepts and open space preservation may be achieved by a developer in
furtherance of the city comprehensive plan and zoning local law or
ordinance.
