Edge). Next is General, the largest zone in most neighborhoods. General is primarily residential, but more urban in character (somewhat higher density with a mix of housing types and a slightly greater mix of uses allowed). At the urban end of the spectrum are two zones which are primarily mixed use: Center (this can be a small neighborhood center or a larger town center, the latter serving more than one neighborhood); and Core (serving the region — typically a central business district). Core is the most urban zone. The character—from rural to highly urban—of each of the zones in the transect continuum is made up not only of the land uses and activities that take place in that zone, but the degree of development and the typology of that development. In contrast to conventional 20th-century zoning, which was for the most part concerned with land uses and activities and largely ignored issues of typology and community form (also known as urban form), transect-based zoning codes take up the issue of development typology as a principal concern. Potentials in Implementation The potential of the transect as an urban planning tool lies in: 1) Education: it is easy to understand 2) Coding: it can be directly translated into the familiar legal framework of Euclidean Zoning districts 3) Immersive environments: this is one where all of the elements of the human environment work together to create something that is greater than the sum of the parts. The transect contains other features: it creates a framework to control and promote growth in certain areas; it intends to increase pedestrian life, local safety, and community identity; and, it provides tools to protect and restore natural environments. A transect is a breakdown of city centre houses out to country houses Challenges to Implementation Many of the features of transect planning cannot be reproduced without a change to municipal ordinances. For example, the transect encourages storefronts to push forward to the sidewalk, to allow window shopping, and push parking lots to the rear. In many municipalities, this design would not be permitted today under town planning bylaws. Hence, any effort to implement the principles of the transect must be accompanied by code changes (See the development of SmartCode).
