Metropolitan regions are finite places with geographic boundaries derived from topography, watersheds, coastlines, farmlands, regional parks, and river basins.
The metropolis has a necessary and fragile relationship to its agrarian hinterland and natural landscapes.
Where appropriate, new development contiguous to urban boundaries should be organized as neighborhoods and districts, and be integrated with the existing urban pattern.
Cities and towns should bring into proximity a broad spectrum of public and private uses to support a regional economy that benefits people of all incomes.
The physical organization of the region should be supported by a framework of transportation alternatives.
