The Transect was developed a century ago as a management tool for the natural environment. Much more recently, Andrés Duany and an expanding band of colleagues (which includes us) have developed the Transect into a robust tool for the human environment as well.
Sprawl recovery is going to take time, and the Transect puts time on our side because with it, we don't have to know where all the lot lines will be in 50 years. We merely need to know what a T5 street (Main Street) or a T4 street (neighborhood street) looks like in our region, and that gives us enough comfort and predictability that we can get started with recovery. Here's more on the details of the Transect Zones, and how the Transect works at the scale of the city.
