PHYSICAL ASPECTS OF CITY PLANNING.

The article focuses on the physical aspects of city planning. Physical factors are those which are inherent in or emanate most directly from the facts of the three-dimensional world. To simplify their exposition, physical factors are divided into three general categories, including long-range, medium-range, and short-range. Climatic changes, natural erosion and, the types and quantities of natural vegetation, all constitute the long range physical factors. Such long-range physical influences are as yet either so unresolved or involve such vast cycles of time that their greatest importance for town planning lies in their function as roots for deductions of more immediate relevance.
