The urban-to-rural transect is a New Urbanist planning framework that prescribes a smooth continuum of settlements that go from least dense to most dense. The six zones are as follows: natural (T1), rural (T2), sub-urban (T3), general urban (T4), center (T5), and core (T6).
Part of this framework is about rejecting single-use Euclidean zoning. Instead of segregating uses, New Urbanism looks to return to a mix of uses within close proximity of each other. This is a good thing.
But the transect also advocates for a certain orderliness. There should be a smooth transition as you move outward from T6 toward T1. It is about placing things in their useful order and maintaining a certain kind of character.
Witold Rybczynski makes an interesting observation about this in a recent post called “urban discontinuities.” The point he makes is that some of the most remarkable urban moments are the result not of smoothness, but of “odd juxtapositions.”
Think:
- Mount Royal (T1) in the middle of downtown Montreal (T6).
- The North Shore Mountains (T1) that terminate views from within the building canyons of downtown Vancouver (T6)
- The walls of tall buildings (T6) that frame Central Park (T1) in Manhattan
