Most types of land uses covered by this Zoning Code are grouped according to compatibility and function, and each group is permitted outright in one or more of the various districts established in the Zoning Code. In addition to these permitted uses, there are other uses which it may be necessary or desirable to allow in certain districts but because of their potential impact on adjacent land or public facilities, require particular and individual consideration prior to location in the community. Such uses are classified in this Zoning Code as "conditional uses."
