How can one expect a rational growth and development of urban communities without a definite guide line for applying fixed elements on city planning such as Park? Introduction: City Planning; the unified development of cities and their environments. For most of its history, city planning dealt primarily with the regulation of land use and the physical arrangement of city structures, as guided by architectural, engineering, and land-development criteria. In the mid-1920th century it broadened to include the comprehensive guidance of the physical, economic, and social environment of a community.Elements characteristic of city planning include (1) General plans that summarize the objectives of land development; (2) Zoning and subdivision controls that specify permissible land uses, densities, and requirements for streets, utility services, and other improvements;(3) Plans for traffic flow and public transportation; (4) Strategies for economic revitalization of depressed urban and rural areas; (5) Strategies for supportive action to help disadvantaged social groups; and (6) Guidelines for environmental protection and preservation of scarce resources. City planning is conducted by governments on all levels—local, county, regional, state, and federal—and by private groups. It is also a subject of university-level study and Professional societies.
