Transect Methodology
The TransectA tool for understanding, categorizing, and designing the natural and build environment from rural to urban.
Encourages diversity of development rather than homogeneity.
![Page 25: Building Support For Form Based Plans - Carlat CNU 17](https://reader033.vdocument.in/reader033/viewer/2022052906/558e24ab1a28ab741f8b459a/html5/thumbnails/25.jpg)
Different transect categories can sit side by side,
but within any transect category, all elements of development should be consistent.
