PLANNING

Zoning

Zoning is the process of dividing an area of
land into districts or zones, and placing
certain development and land use
restrictions on these areas. It is a means by
which the development and growth of a
community may be controlled.

Zoning is an important, if not critical, tool
for successful mitigation against any type
of disaster. By implementing height,
weight, bulk, and design limitations, as
well as penalties for development within
designated areas, an environmentally safe
and stable community may be achieved.

environment and discourages llIIY misuse of
land.

Implementation of zoning ordinances
should be structured so all adjacent
properties are under similar restrictions to
avoid conflict between patrons that have
adjacent properties. High hazard areas,
such as floodplains, may eventually be
converted into recreational parks, parking
lots, agricultural land, or wildlife
sanctuaries, which all lessen risk associated
with flood.

Land Use Planning

Land use planning encourages people to
avoid hazardous zones. There are four
basic aspects of land use plllIlllip.g:

Public Acquisition - is government
ownership of potentially hazardous land
