Under some unusual circumstances, a use which more intensely affects an area than those uses permitted in the zoning district in which it is located may nonetheless be compatible with permitted uses, if that use is properly controlled and regulated. Such uses shall be listed as conditional uses within the respective zoning districts. The Board of Zoning Appeals may grant conditional approval for use of the land, buildings, or other structures and may allow such a use to be established where unusual circumstances exist and where the conditional use will be consistent with the general purpose and intent of this Zoning Resolution.
