The regulations set forth in this Chapter are designed to deal with certain types of problems which arise only in connection with large-scale residential developments and to promote and facilitate better site planning and community planning through modified application of the district regulations in such developments.

For large-scale residential developments involving several zoning lots but planned as a unit, the district regulations may impose unnecessary rigidities and thereby prevent achievement of the best possible site plan within the overall density and bulk controls. For such developments, the regulations of this Chapter are designed to allow greater flexibility for the purpose of securing better site planning for development of vacant land and to provide incentives toward that end while safeguarding the present or future use and development of surrounding areas and, specifically, to achieve more efficient use of increasingly scarce land within the framework of the overall bulk controls, to enable open space in large-scale residential developments to be arranged in such a way as best to serve active and passive recreation needs of the residents, to protect and preserve scenic assets and natural features such as trees, streams and topographic features, to foster a more stable community by providing for a population of balanced family sizes, to encourage harmonious designs incorporating a variety of building types and variations in the siting of buildings, and thus to promote and protect public health, safety and general welfare.
