"Planned development" means a tract of land which is planned as a whole for development under single ownership or control and which, by virtue of such unified planning and development, provides greater amenities, convenience or other benefits than would normally be had through the development of diverse smaller tracts under multiple ownership. In the case of a residential planned development, adequate provision shall be made for basic community facilities such as schools, parks, playgrounds and churches, among others.
The minimum area for a planned development shall be:
(a) For residential, forty acres;
(b) For business, five acres;
(c) For industrial, twenty acres; and
(d) For governmental, three acres.
