The Changing American Dream: From Surburbia to Walkable Neighborhoods

High gas prices, long commutes, and the subprime mortgage crisis have hit Surburbia hard and people have started to rethink where they want to live. People are now finding walkable urban areas and walkable neighborhoods more attractive instead of a house in suburbia.

"The American dream is absolutely changing," he told CNN.

This change can be witnessed in places like Atlanta, Georgia, Detroit, Michigan, and Dallas, Texas, said Leinberger, where once rundown downtowns are being revitalized by well-educated, young professionals who have no desire to live in a detached single family home typical of a suburbia where life is often centered around long commutes and cars.

Instead, they are looking for what Leinberger calls "walkable urbanism" -- both small communities and big cities characterized by efficient mass transit systems and high density developments enabling residents to walk virtually everywhere for everything -- from home to work to restaurants to movie theaters.

The so-called New Urbanism movement emerged in the mid-90s and has been steadily gaining momentum, especially with rising energy costs, environmental concerns and health problems associated with what Leinberger calls "drivable suburbanism" -- a low-density built environment plan that emerged around the end of the World War II and has been the dominant design in the U.S. ever since.
