What is zoning?
Zoning is the practice of allocating different areas of a Town, or City different uses. Zoning is an explicit and legal way of ordering land uses and is the basic tool of urban planning today. Through zoning, local governments have the legal obligation (police power given to them by state goveernments) to relate every piece of private property to all others and to be concerned about the health, safety and well being of the community (http://www.uwec.edu/geography/Ivogeler/w270/zoning-history.htm).
Zoning allows a local government to control and regulate the uses and characteristics of buildings, structures, and land within its boundaries. The authority for zoning is broadly based on a community's police power, allowing for the protection of the public's health, safety, and general welfare (http://archive.cityofpaloalto.org/knowzone/news/details.asp?NewsID=787&TargetID=239#introduction).

Types of zoning
There are several types of zoning codes in use today and combinations thereof.

What is Sustainable Development (SD)?

It contains within it two key concepts:
Thus the goals of economic and social development must be defined in terms of sustainability in all countries - developed or developing, market-oriented or centrally planned. Interpretations will vary, but must share certain general features and must flow from a consensus on the basic concept of sustainable development and on a broad strategic framework for achieving it.
Development involves a progressive transformation of economy and society. A development path that is sustainable in a physical sense could theoretically be pursued even in a rigid social and political setting. But physical sustainability cannot be secured unless development policies pay attention to such considerations as changes in access to resources and in the distribution of costs and benefits. Even the narrow notion of physical sustainability implies a concern for social equity between generations, a concern that must logically be extended to equity within each generation.
The Concept Sustainable Development focuses on the following:
