A.
The Town of Yorktown, New York, has provided in its Development Plan, as amended to June 1961, and as implemented by its this chapter, as amended to July 1964, ample lands for sale to and use and occupancy by persons of all ages, financial circumstances and family conditions, as well as sufficient and suitable lands for nonresidential purposes and for the population contemplated in said Development Plan for years still to come. The establishment of a special classification for the age-oriented community will leave ample lands available in the Town for other types of housing accommodations for those not yet qualifying under this classification. Without even considering the land zoned in such manner as to be available for general residence use in neighboring Towns within this county, the immigration to the Town of Yorktown of citizens of more modest means or those desiring space to raise their families will in no way be detrimentally affected.
B.
The purpose of the age-oriented community is to permit the establishment, within residential areas, of a specialized residential development for older persons, in which development certain accessory uses requisite to the mode of living and age of, or desirable and convenient for use by, a group of residents having the characteristics of those qualified by definition to inhabit the structures constituting such specialized residential development are permitted. There is an increasing demand by persons of or nearing retirement age for dwelling accommodations in a developed, separate residential section in which a greater degree of tranquillity is assured through the zoning classifications, which will be inhabited by persons similarly circumstanced and which have been designed and developed for such age group. It is further provided that such age-oriented community be considered and made part of a larger, overall residential neighborhood. Not only is it considered the duty of a municipal government to provide space within its boundaries for this group of citizens which, as the science of geriatrics advances, grows larger daily, but it is to the benefit of the Town and its other residents to do so.
C.
Such persons form a stable part of the community. In contrast to young families which are often compelled to move as their families grow or jobs change, retired persons set their roots fast in the community, usually for the rest of their span of life. They have no need for schools and related services, nor do they require, in the aggregate, as many municipal services and facilities. The taxes paid by them, directly or indirectly, help to stabilize the tax base required to provide schools and other public services in those areas and for those land uses which require them. Usually having a greater-than-average purchasing power, they bolster the local economy and aid in the expansion and development of local business districts. The manner in which they use the physical premises where they reside is less apt to disturb the peace and tranquillity of the neighborhood than the use of property by younger persons with families, with greater outdoor activity, greater social activity taking place on the premises and greater traffic at all times on and onto the premises.
D.
Moreover, it has been determined that a minimum amount of retail trade and services, professional and other, may be carried on in such specialized development for the convenience of its inhabitants, some of whom will, by reason of age or reduced physical fitness, be unable to travel beyond the development itself without difficulty and some of whom will have no means of individual transportation. Such accessory uses and others permitted hereby will, it is likely, diminish the amount of vehicular movement within and to and from such community, thereby promoting its tranquillity and the public health, safety and general welfare. The more stringent requirement of site approval than that required elsewhere and the age and composition of the residents therein give ample assurance that such accessory uses in such specialized residential development community will have no adverse effect upon neighboring properties or land uses and warrant their inclusion as permitted accessory uses and sufficiently distinguish such community from other residentially zoned districts.
