Urban sprawl is difficult to define but people usually know it when they see it.

Urban sprawl, also known as suburban sprawl, is the spreading of a city and its suburbs over rural land at the fringe of an urban area. Residents of sprawling neighborhoods tend to live in single-family homes and commute by automobile to work. Low population density is an indicator of sprawl. Urban planners emphasize the qualitative aspects of sprawl such as the lack of transportation options and pedestrian friendly neighborhoods. Conservationists tend to focus on the actual amount of land that has been urbanized by sprawl.

From Wikipedia, the free encyclopedia

It all began during the post-war prosperity of the 1950's and 60's, when housing developments popped up across the landscape like mushrooms after a rain. A half-century later, we now understand that many environmental problems accompany the outward spread of cities: fragmenting and destroying wildlife habitat, for example, and discharging polluted runoff water into streams and lakes.
