Soil Soil is the layer of broken rock particles and decaying organic matter on the surface of earth, which is essential for the growth of plants. The kind of soil in a region determines the depth of foundations, earthquake vulnerability and general stability of structures. Delhi is composed mainly of alluvial soil with ranging age. Its physiographic distribution is:
Alluvial plain on eastern and western sides of the ridge Yamuna flood plain deposits Isolated and nearly closed Chattarpur alluvial basin NNE-SSW trending Quartzitic Ridge.

The ridge region is mainly quartzite stone and is hence hard and impenetrable. Inferences • As is visible from the map, very little construction activity has occurred over the quartzite ridge region. This limits location for housing projects • Major construction activity has taken place in the region of high alluvium concentration. But low yield prospects. • Regions with high yield are relatively free of construction activity. • Groundwater availability is also determined by the penetrability of soil, hence areas with harder soil conditions such as ridge have limited groundwater resources, hence limiting scope of construction activity due to lack of availability of water.
