In restless dreams I walked alone
Narrow streets of cobblestone
Beneath the halo of a streetlamp
I turned my collar to the cold and damp
When my eyes were stabbed by the flash of a neon light
That split the night
And touched the sound of silence
How much more mysterious and inviting is the street of an old town with its alternating realms of darkness and light than are the brightly and evenly lit streets of today! Homogenous bright light paralyzes the imagination in the same way that homogenization of space weakens the experience of being, and wipes away the sense of place. The human eye is most perfectly tuned for twilight rather than bright daylight.
I have for years been engaged in a thought experiment, the product of which is the idea of a program of “greenfill” for the city streets. The idea is simple: if one lane of every block in the city were removed from the automotive system and returned to the pedestrian realm, an enormous range of urban problems could be solved.
Along with being a meeting place, the stoop is a space of spectatorship. A street lined with stoops is a kind of lateral stadium, ideal for viewing the passing parade, whether formal ones like the giant Gay Pride and Halloween Parades (until their route was changed a few years ago) or the more informal quotidian version. Hanging out on the stoop allows the sitter to observe the dance (Jane Jacobs’s ballet) of daily activity, to notice what is out of the ordinary, to provide the kind of public presence that prompts neighborly behavior.
To generate exuberant diversity in a city’s streets and districts, four conditions are indispensable:
- The district, and indeed as many of its internal parts as possible, must serve more than one primary function; preferably more than two. These must insure the presence of people who go outdoors on different schedules and are in the place for different purposes, but who are able to use many facilities in common.
- Most blocks must be short; that is, streets and opportunities to turn corners must be frequent.
- The district must mingle buildings that vary in age and condition, including a good proportion of old ones so that they vary in the economic yield they must produce. This mingling must be fairly close-grained.
- There must be a sufficiently dense concentration of people, for whatever purposes they may be there. This includes dense concentration in the case of people who are there because of residence.
A city street equipped to handle strangers, and to make a safety asset, in itself, out of the presence of strangers, as the streets of successful city neighborhoods always do, must have three main qualities:
- First, there must be a clear demarcation between what is public space and what is private space.
- Second, there must be eyes upon the street, eyes belonging to those we might call the natural proprietors of the street.
- And third, the sidewalk must have users on it fairly continuously.
Streets and their sidewalks, the main public places of a city, are its most vital organs.
They serve many purposes besides carrying vehicles, and city sidewalks—the pedestrian parts of the streets—serve many purposes besides carrying pedestrians. These uses are bound up with circulation but are not identical with it and in their own right they are at least as basic as circulation to the proper workings of cities.
- Think like a gardener, not an architect: design beginnings, not endings
- Unfinished = fertile
- Artists are to cities what worms are to soil.
- A city’s waste should be on public display.
- Make places that are easy for people to change and adapt (wood and plaster, as opposed to steel and concrete.)
- Places which accommodate the very young and the very old are loved by everybody else too.
- Low rent = high life
- Make places for people to look at each other, to show off to each other.
- Shared public space is the crucible of community.
- A really smart city is the one that harnesses the intelligence and creativity of its inhabitants.
This is a famous picture by the artist Imperial Boy (帝国少年), who works in the anime industry. I sometimes claim that the entire genre of solarpunk is simply a riff on this picture.
If it’s not just “trees on buildings”, where does the Imperial Boy picture get its magic? Looking at it carefully and trying to analyze what I like about it, I think that much of it is about architecture, and even more of it is about the use of urban space — about how the structures in the picture shape the kinds of things you’d do if you were there. For example, here are five things I like:
- Open, walkable multi-level retail
- River with low bank
- Walkable streets
- Varied architecture
- Shade
My article “Off the Grid… and Back Again? The Recent Evolution of American Street Network Planning and Design” has been published by the Journal of the American Planning Association and won the 2020 Stough-Johansson Springer Award for best paper. It identifies recent nationwide trends in American street network design, measuring how urban planners abandoned the grid and embraced sprawl over the 20th century, but since 2000 these trends have rebounded, shifting back toward historical design patterns.
This order is all composed of movement and change, and although it is life, not art, we may fancifully call it the art form of the city and liken it to the dance—not to a simple-minded precision dance with everyone kicking up at the same time, twirling in unison and bowing off en masse, but to an intricate ballet in which the individual dancers and ensembles all have distinctive parts which miraculously reinforce each other and compose an orderly whole. The ballet of the good city sidewalk never repeats itself from place to place, and in any one place is always replete with new improvisations.
