The development and enactment of a zoning ordinance is based upon the division of the city into districts, within which districts the use of land and buildings and the bulk and location of buildings and structures in relation to the land are mutually compatible. It is recognized, however, that there are uses which, because of their unique characteristics, cannot be properly classified in any particular district or districts without consideration, in each case, of the impact of those uses upon neighboring land and of the public need for the particular use at the particular location. Such special uses fall into three (3) categories:
A. Uses either publicly operated or operated by publicly regulated utilities or uses traditionally affected by public interest.
B. Uses entirely private in character but of such an unusual nature that their operation may give rise to unique problems with respect to their impact upon neighboring property or public facilities.
C. Nonconforming uses which, as special uses, can be made more compatible with their surroundings. (Ord. B-39, 1969)
