Zoning in Urban Town Planning

Definition

It is the distribution or division of land (in town planning) into particular zones based upon some criteria or principles.

Principles of zoning

The principles of zoning include the following elements which are given importance while zoning an area.

1. Concentric growth
2. Boundary
3. Existing towns
4. Flexibility
5. New towns

a. Concentric growth

The growth of buildings which spread from a center in all directions is called concentric growth. These types of buildings usually for a ring and consists of residential buildings surrounded by commercial areas. This type of growth is natural and totally unplanned. When the population goes on increase, the concentric circles are again surrounded by people - these areas are called the suburbs of the city.

b. Boundary

Boundaries are the important element in zoning. Usually the boundaries between two zones can be road, railway line, river, a wall or a green belt. Green belt is preferred to all others. The existence of boundaries depends on the rule of law. Sometimes boundaries are broken and two zones seem to mix. This type of area is then called transition zone.

c. Existing towns

While zoning and planning new towns, the planner must keep in mind the convenience of existing towns. Zoning should be done in such a way so as not to disturb the ecosystem of the already existing towns.

d. Flexibility

The zoning of an area should be as such so as to provide maximum comfort and convenience to people. Zoning should also be done in such a way that in future new towns can be made and there is room for expansion of the zone.

e. New towns

New towns should be provided room for in zoning of site.
