New Urbanism

"New Urbanism is an American urban design movement that arose in the early 1980s. Its goal is to reform many aspects of real estate development and urban planning, from urban retrofits to suburban infill. New urbanist neighborhoods are designed to contain a diverse range of housing and jobs, and to be walkable.

New Urbanism can include (neo)traditional neighborhood design and transit-oriented development."
