      C.   Public assemblies, displays, and exhibits.
      D.   Commercial circuses, carnivals, fairs, festivals, or other transient events, provided that events are located on property owned by the sponsoring non-profit organization, or are located within a BG or more intensive zoning district.

      B.   The Zoning Administrator may authorize a temporary use only if such official determines that:
         (1)   The use will not impair the normal operation of a present or future permanent use on the site.
         (2)   The use will be compatible with surrounding uses and will not adversely affect the public health, safety, and welfare.
