complementary uses. Zoning can also provide the opportunity to
stimulate or slow down development in specific areas.
Advantages of zoning

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

community by requiring landscaping, buffers, and parking lot
improvements.
