What is Zoning?

The local governments in developed countries designated permitted uses of land based on mapped zones. The mapped zones help in separating one set of land uses from another. This device of land use planning is called zoning.(1) Zoning is one of the principles of town planning.

Zoning is used to specify the use of land and is called functional zoning. It is also used to regulate the height of the buildings and density (ground coverage specifications).

A town/city is divided into different zones such as:

  1. Residential zone (housing)
  2. Commercial zone (retail/wholesales shops/malls – anything related to commerce)
  3. Industrial zone (Industries/factories)
  4. Recreational zone (Parks/Playgrounds/spaces for recreational activities)
  5. Mixed use zone (Commercial + Residential)

All of the above mentioned zones cater to their specify type of usage.

Why is Town planning important?

It is evident that a small house if well arranged and planned, looks far more better than a disordered big palace. In a similar way, a town which is properly planned provide people with more comfort and convenience.

The necessity of town planning can very well be appreciated by mentioning the evil situations which a town has to face in the absence of town planning. They are as follows:

1. Defective road system resulting in the formation of narrow streets and lanes;

Defective road system is a problem in most countries. It is due to the fact that towns and cities were never planned. They gradually grew with the help of the developers which resulted in bad road network giving rise to bad transportation network.

Principles of Town Planning

Town planning cannot be studied in isolation. It involves the study of various subjects such as engineering, architecture, surveying, transportation planning etc. The intention of the town planning is to satisfy the needs of our future generations and prevent the haphazard growth of the town. Some of the guiding principles of town planning are as follows:

1. Zoning

The town should be divided into suitable zones such as commercial zone, industrial zone, residential zone, etc and suitable rules and regulations should be formed for the development of each zone.

2. Green belt

Green belt is non-development zone on the periphery of the town. It prevents the haphazard sprawl of the town restricting its size. In essence, a green belt is an invisible line designating a border around a certain area, preventing development of the area and allowing wildlife to return and be established. Greenways and green wedges have a linear character and may run across the town and not around the town.

3. Housing

Housing has to be carefully studied and designed to suit the local population. Care should be taken to see that there is no development of slums since it would be responsible for degrading the life of the citizens. There are various types of housing styles. When a landuse plan is made, zones for independent housing, midrise buildings, high rise buildings are allocated. Landuse maps are of two types. Type 1 helps us study the landuse on a broad range. All we can see are the residential, commercial and recreational zones.
