Paved paradise? Impervious surfaces affect a region's hydrology, ecosystems—even its climate

Science News, Sept 4, 2004 by Sid Perkins

Ecoroofs are only one of many prospective techniques to avoid the effects of impervious surfaces. Some developers, for example, are digging large, shallow ponds where runoff can collect and seep into aquifers rather than rush into streams and increase erosion.

These approaches may permit further urban and suburban development without exacerbating the problems associated with impervious surfaces.
