Protecting Water Resources with Smart Growth U S Environmental Protection Agency

Publisher Marketing: How are zoning codes and building designs related to standards established by the Clean Water Act? How do transportation choices or the mix of uses in a district affect the quality and quantity of stormwater runoff? How are development patterns associated with protecting the nation's water resources, including lakes, rivers, streams, and aquifers? As studies have shown, growth and development can have profound effects on our water resources. Storm sewer overflows and polluted runoff from non-point sources are a major reason that some water bodies do not meet Clean Water Act (CWA) standards. One factor related to persistent water pollution problems is our development patterns, particularly patterns of highly dispersed development that have been common since the end of World War II. The more woodland, meadowland, and wetland areas disappear under impermeable cover, and the more miles and vehicles we drive and park on impermeable roads and highway surfaces, the more difficult protecting the quality and quantity of our water supplies becomes. In response to these current trends, local governments are developing smarter approaches to growth. They are looking for, and using, policies and tools that enhance existing neighborhoods, improve schools, protect drinking water, and provide solid housing and transportation choices. These communities are seeking smart growth-a development approach characterized by 10 smart growth principles. These principles support economic development and jobs; create strong neighborhoods with a range of housing, commercial, and transportation options; and achieve healthy communities and a clean environment. "Protecting Water Resources with Smart Growth" is intended for audiences already familiar with smart growth, who now seek specific ideas on how techniques for smarter growth can be used to protect their water resources. Smart growth principles provide a foundation-a basic springboard-for the 75 policies described in this report. The majority of these policies (46) are oriented to the watershed, or regional level; the other 29 are targeted at the level of specific development sites.
