Urban fabric is the physical form of towns and cities. Like textiles, urban fabric comes in many different types and weaves.

For simplicity’s sake, I am going to divide the multiple of different urban fabrics into two typologies: coarse grain and fine

grain:

COARSE GRAIN

“Long blocks isolate the users of one street from the next one over. This isolation reduces the capability of those

living on these streets to jointly support retail establishments.” —Jane Jacobs

Coarse grain urban fabric is like burlap: rough, large-scale weaves that are functional, but not usually comfortable. Such

places consist of one of two things. Large blocks, predominated by big box stores and other car contract retail and corporate

centers, or multi block mega project dropped on a city without integrating the surrounding city or community. In downtown

Phoenix, developments like Arizona Center and CityScape come to mind.

Not only do coarse grain fabrics NOT provide many opportunities for interconnecting; the fabric itself is usually inhospitable to

interaction. Instead of asserting control over the street, such places turn inward, fortifying themselves against the perceived

dangers of the outside. This begets yet more undesirability. In this regard coarse grain acts as a barrier for all but those who

are there for a specific purpose. Just as we are not comfortable wearing a burlap shirt, we are not comfortable spending more

time them necessary in coarse-grained places.

…the effect of putting an enormous single-purpose entity within this fine network of the city core is the same as

putting a huge field of a single crop in the middle of an ecology: it renders the whole thing essentially sterile,

incapable of generating anything new. —James Howard Kunstler

FINE GRAIN

Street patterns must be easily navigable and lattice like, with blocks that are not too big and intersections that

are not too far apart. —Roger Lewis

On the other hand, there is fine-grained urban fabric. Like high count egyptian (or perhaps pima) cotton; fine grain urban

fabric can feel luxurious and want to make people linger in or around it. Fine grain urban fabric consists of several small

blocks in close proximity. Within each block are several buildings, most with narrow frontages, frequent store fronts, and

minimal setbacks from the street. Streets and opportunities to turn corners are frequent, and as a result, so are storefronts.

This offers many opportunities for discovery and exploration. There are virtual no vacant lots or surface parking. Also, as

there are more intersections, traffic is slower and safer.

Fine grained urban fabric is not imposed on a community like its coarse cousin. Rather, it evolves over time in a piecemeal

way, responding to what came before, and adapting to what came afterwards. This evolutionary process creates place that

are not frozen in the era when they were built, but are dynamic and reflective of a neighborhood’s changing needs. This

creates an urban fabric that can seamlessly evolve over time from lightly developed residential areas to mixed-used retail to

dense urban core, if that’s what the community desires. In this way, there are far more resilient than the mega projects

mentioned above who, when they lose a single tenant, often fail.
