The purpose of this subdivision is to permit development of projects consisting of
residential, commercial or industrial, or any combination of residential, industrial
and commercial uses, as permitted herein, within a single development under a unified

standards relative to specific dimensional regulations, encourage ingenuity and originality
in subdivision and site design while preserving open space to serve recreational,
scenic and other public service purposes, ensure compatibility of new development
with the surrounding area, and facilitate the provision of mixed uses including housing
types and housing cost levels within the same project.
