These land uses could not be conveniently allocated to one zone or another, or the effects of such uses could not be definitely foreseen as of a given time. The general characteristics of these uses include one or more of the following:

They require large areas.
(2)
They are infrequent.
(3)
They sometimes create an unusual amount of traffic.
