The Street
“Every trip begins with a step”
“Life takes place on foot” – Jan Gehl
The Charter of the New Urbanism
The region: metropolis, city, and town
The neighborhood, the district, and the corridor
The block, the street, and the building
Sustainable: over what period of time?Equitable: for whom?
