Flooding of low lying areas due to heavy rains, flash floods inundation and consequent heavy demages to properties and lives are the common features in many of the urban areas of the world. Apparently the pace of urban growth is at a faster rate when compared to the protective measures undertaken. The increasing demand for land utilization, the cost and opportunity factors etc more often outbeat the effectiveness of the development control stipulations of the local Govts for these areas. Though the environmental hazards are common in both the developed and developing world yet the dimension and magnitude of the problem varies in relation to the geographical location, socio-economic texture of the urban society and the function of the urban areas. More often the frequent occurance of flooding poses a host of urban planning and development issues for deeper understanding of the problems involved and the efforts needed to be undertaken by the Govts concerned. Several earlier studies and efforts either proved to be inadequate or not in tune with the dimensions of the problem as they lacked a comprehensive approach and concrete solution. In this paper an attempt has been made to bring out the various facets of flooding hazards, the environmental and planning issues involved and measures undertaken and needed to be undertaken to mitigate the problems in the city of Sapporo of Japan and Madras of India.
