A neighborhood standing alone can be a village or a town. A cluster of neighborhoods becomes a bigger town. Clusters of a great many neighborhoods become a city. The population of a neighborhood can vary, depending on local conditions. The neighborhood is limited in physical size, with a well-defined edged and a focused center.
Human scale is the standard for proportion in buildings and their accessories.
Automobiles and other wheeled vehicles are permitted, but do not take precedence over human needs, including aesthetic needs. The neighborhood contains a public transit stop. The secondary units of assembly are corridors and districts. Corridors form the boundaries between neighborhoods, both connecting and defining them. The neighborhood is emphatically mixed-use and provides housing for people with different incomes.
