requirement, building size, and other development standards. These
restrictions and standards help prevent overcrowding in the specified
area by limiting the amount and sizes of structures and parcels.
 Zoning protects existing property values by preventing incompatible
uses of a property. For example, a bar would not be allowed near an
elementary school
