Planned unit developments may be established by amendments to the official Zoning Map in any existing residential district where tracts suitable in location and character for the uses and structures proposed are to be planned and developed as units, according to the requirements and procedures set forth in this article. Unified tracts of land for planned unit developments shall contain a minimum of five acres of land.
Planned unit developments shall be appropriately located with respect to the general pattern of urban development, existing or proposed, and to public and private facilities and services, existing or clearly to be available by the time development reaches the stage where they will be required. The following specific requirements shall be met:
(a) Relation to Major Transportation Facilities. Planned unit developments shall be located with respect to major streets and highways or other transportation facilities so as to provide direct access to such districts without creating traffic along minor streets in residential neighborhoods outside such districts.
(b) Relation to Utilities and Public Facilities. Planned unit developments shall be located in relation to sanitary sewers, water lines, storm and surface drainage systems and other utilities systems and installations so that neither extension nor enlargement of such systems will be required in manner, form, character, location, degree or scale of timing, resulting in higher net public cost or earlier incursion of public cost than would development in a form generally permitted in the area. Such districts shall be located with respect to schools, parks, playgrounds and other public facilities required so as to have access in the same degree as would development in a form generally permitted in the area.
(c) Physical Characteristics of Site. The site shall be suitable for development in the manner proposed without hazards to persons or property on or off the site from probability of flooding, erosion, subsidence or slipping of the soil or other dangers, annoyances or inconveniences. The condition of the soil, ground water level, drainage and topography shall be appropriate to both kind and pattern of use intended.
