Within certain districts now existing or which may hereafter be created, it is intended to permit, on application and on approval of detailed site and building plans, planned unit developments, primarily for housing, where tracts suitable in location and character for the uses and structures proposed are to be planned and developed as units. Within such planned unit developments, regulations adapted to such unified planning and development are intended to accomplish the purposes of zoning and subdivision regulations to the same degree as in those districts in which regulations are desired to control development which is not on a similarly unified basis; however, it is expressly intended that the planned unit developments provide a method of development for land that permits variation in lot sizes without an increase in the density of population or development, that allows subdivisions with varying lot sizes so as to allow home buyers a choice of lot sizes according to their needs, that preserves open space, tree cover, scenic vistas, natural drainageways and outstanding natural topography, that prevents soil erosion by permitting lot sizes according to the nature of the terrain within the development, that provides larger open areas with greater utility for open space and recreation and that encourages the development of more attractive and economic and less monotonous building forms by providing freedom of architectural and site design.
