Conventional Suburban Development (CSD) vs. Traditional Neighborhood Development (TND)

This diagram (above) presents a caricature of Conventional Suburban Development, or CSD (top), as contrasted with Traditional Neighborhood Development, or TND (bottom), as alternative models and patterns of development. Sprawl is characterized by the separation of uses (mall, apartments, houses, school) in a low-density, dispersed pattern that is automobile-dependent.The traditional neighborhood mixes uses and different types of housing in an interconnected pattern of streets and blocks that create a walkable neighborhood.
