Urban form and grain
One square mile of different cities' street networks, held at the same scale to compare the urban form and grain.
Names vs. The Nothing
This is the first site along the tour. In here we have a void. I remember the building that used to stand here, it was painted blue. Passing through it, you can imagine how us, as ghosts – should the building be standing here – would have to actually be invisible to pass through these walls and now it’s the reverse. The building is the ghost and we’re passing through these walls.
The linear city
The linear city was an urban plan for an elongated urban formation. The city would consist of a series of functionally specialized parallel sectors.
As the city expanded, additional sectors would be added to the end of each band, so that the city would become ever longer, without growing wider.
A dialogue between homogeneity and exception
All cities can be described as a dialogue between homogeneity and exception, and each strikes a particular balance that is at the core of its character.
Ground displaced upward
Imagine that our rooftops were parkland, that the area of ground occupied by buildings was, in effect, simply displaced upward. Imagine that the city enacted legislation requiring that the equivalent of 100 percent of the surface area of New York were to be green. A 100 percent requirement would not simply oblige green roofs. It would also demand that compensatory greenery be added to make up for such ungreenable areas as roadways, runways, and other unplantable places. Perhaps the requirement would be satisfied with road narrowings, cantilevered gardens, or green floors in buildings (utilities on the order of the mechanical floors that occur in almost all tall buildings).
Same name in the same basket
Does a concert hall ask to be next to an opera house? Can the two feed on one another? Will anybody ever visit them both, gluttonously, in a single evening, or even buy tickets from one after going to a performance in the other?
In Vienna, London, Paris, each of the performing arts has found its own place, because all are not mixed randomly. The only reason that these functions have all been brought together in Lincoln Center is that the concept of performing art links them to one another. The organization is born of the mania every simple-minded person has for putting things with the same name into the same basket.
A city cannot be a work of art
There is a basic esthetic limitation on what can be done with cities: A city cannot be a work of art.
The kind of problem a city is
Dr. Weaver lists three stages of development in the history of scientific thought: (1) ability to deal with problems of simplicity; (2) ability to deal with problems of disorganized complexity; and (3) ability to deal with problems of organized complexity.
The history of modern thought about cities is unfortunately very different from the history of modern thought about the life sciences. The theorists of conventional modern city planning have consistently mistaken cities as problems of simplicity and of disorganized complexity, and have tried to analyze and treat them thus.
These loose notes
These loose notes are one possible description of our city. A city that, as in Constantin Cavafy's poem The City, is and always will be the same, in the same city again.
Strands of life
For the human mind, the tree is the easiest vehicle for complex thoughts. But the city is not, cannot, and must not be a tree. The city is a receptacle for life. If the receptacle severs the overlap of the strands of life within it, because it is a tree, it will be like a bowl full of razor blades on edge, ready to cut up whatever is entrusted to it. In such a receptacle life will be cut to pieces. If we make cities which are trees, they will cut our life within to pieces.
Natural and artificial cities
I want to call those cities which have arisen more or less spontaneously over many, many years natural cities. And I shall call those cities and parts of cities which have been spontaneously created by designers and planners artificial cities. Siena, Liverpool, Kyoto, and Manhattan are examples of natural cities. Levittown, Chandigarh, and the British New Towns are examples of artificial cities.
It is more and more widely recognized today that there is some essential ingredient missing from artificial cities.
Tree, leaf, house, city
"Tree is leaf and leaf is tree – house is city and city is house. A city is not a city unless it is also a huge house – a house is a house only if it is also a tiny city."
— Aldo van Eyck
To become completely lost
To become completely lost is perhaps a rather rare experience for most people in the modern city. We are supported by the presence of others and by special way-finding devices: maps, street numbers, route signs, bus placards. But let the mishap of disorientation once occur, and the sense of anxiety and even terror that accompanies it reveals to us how closely it is linked to our sense of balance and well-being. The very word "lost" in our language means much more than simple geographical uncertainty; it carries overtones of utter disaster.
Junctions
The junction, or place of a break in transportation, has compelling importance for the city observer. Because decisions must be made at junctions, people heighten their attention at such place and perceive elements with more than normal clarity. This tendency was confirmed so repeatedly that elements located at junctions may automatically be assumed to derive special prominence from their location.
A certain plasticity
There are dangers in a highly specialized visible form; there is a need for a certain plasticity in the perceptual environment. If there is only one dominant path to a destination, a few sacred focal points, or an ironclad set of rigidly separated regions, then there is only one way to image the city without considerable strain. This one may suit neither the needs of all people, nor even the needs of one person as they vary from time to time. An unusual trip becomes awkward or dangerous; interpersonal relations may tend to compartmentalize themselves; the scene becomes monotonous or restrictive.
A metropolis for hydrocarbons
An oil refinery suggests the image of a metropolis for hydrocarbons, the pipe manifolds like expressways, the distillation towers like skyscrapers.
Roads to nowhere
Among real-estate developers, straight lines and right angles went out of fashion sometime in the middle of the twentieth century. If you look at a town or a residential neighborhood laid out since then, you are more likely to find sinuous, serpentine roads—whether or not the topography offers any excuse for such curves. Many of these roads go nowhere: they are loops that bring you back to where you started, or they are cul-de-sacs. Making it easy to find your way through the network of streets is obviously not a high priority. This is an interesting development in urban geography: having redesigned the city to accommodate the automobile, we now search for ways to discourage people from driving on the streets.
Dead cities
If you can understand a city, then that city is dead.
NYLA
"See, what I've always liked about Los Angeles is that it's one of the least restrictive towns in the world. You can pretty much live any way you want to here. And part of that is because the place has no tradition and no history in that sense. It doesn't have any image of itself, which is exactly its loss and gain. That's why it's such a great place to do art and to build your ideas about culture. In New York, it's like an echo chamber: its overwhelming sense of itself, of its past and its present and its mission, becomes utterly restricting."

A Book by Robert McCarter & Juhani PallasmaaWhy I Walk
An Article by Chris ArnadeOn my first day I literally walk across the city, to the extent it can be done…The next day I do another cross town walk, but in a different direction, filling in the blanks from the prior day’s walk.
Then, over the next week(s), I walk between 10 to 20 miles per day, picking and choosing from what I have seen before, highlighting what I like, what I want to know more about, refining the path, till by the end of my trip, I have a daily route that is roughly the same.
While that is certainly not the most efficient way to see a city, it is the most pleasant, insightful, and human. I don’t think you can know a place unless you walk it, because it isn’t about distance, but about content.

Tilted Arc
An Artwork by Richard SerraIn the 1980s, Serra found himself in the center of a public controversy over his piece titled Tilted Arc. While it was the government that approached him to create the work for downtown Manhattan’s Federal Plaza, the unveiling of the piece in 1981 was met with sharp criticism. The monumental sculpture was said to disrupt rush hour and the pedestrians who had to cut through the plaza daily. To the dismay of art lovers, the 120-foot-long, 12-foot-tall Tilted Arc was ultimately disassembled in 1989.
Working with Brian Eno on design principles for streets
- 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.
Towers in the Village
An Essay by Alfred TwuSince tall buildings have been around, there have been many ways they’ve fit into cities: towers in downtown, towers in the park, and most recently, towers on a whole-block development. Let’s look at a 4th way, the Tower in the Village.
Unlike the others, the Tower in the Village does not aim to be the center of attention. Instead, the upper floors are hidden behind a low front that fits in with the rest of the block. It faces a village green instead of a busy road.
Why highrise infill? Growing cities have two choices: 1) Redevelop a lot of sites to medium density, or 2) Redevelop a small number of sites to very high density. Highrise infill requires less demolition and can get more homes built faster.
Clues for software design in how we sketch maps of cities
An Article by Matt WebbGiven there’s an explosion in software to accrete and organise knowledge, is the page model really the best approach?
Perhaps the building blocks shouldn’t be pages or blocks, but
neighbourhoods
roads
rooms and doors
landmarks.Or rather, as a knowledge base or wiki develops, it should - just like a real city - encourage its users to gravitate towards these different fundamental elements. A page that starts to function a little bit like a road should transform into a slick navigation element, available on all its linked pages. A page which is functioning like a landmark should start being visible from two hops away.

Psychogeography
A Definition by Guy DebordPsychogeography is an exploration of urban environments that emphasizes playfulness and "drifting". It was defined in 1955 by Guy Debord as:
- "The study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behavior of individuals."
- "A total dissolution of boundaries between art and life."
- "A whole toy box full of playful, inventive strategies for exploring cities...just about anything that takes pedestrians off their predictable paths and jolts them into a new awareness of the urban landscape."
Title Cities
An Artwork by Nicholas RougeuxA book’s title page contains more than its namesake—including its author, contributors, publisher, and release date, and. Antiquarian books are known for having lengthy titles, especially those of a scientific nature. These books’ frequently unassuming title pages are gateways to a wealth of knowledge and the focal point of this project.
Title pages of antique influential scientific books covering a variety of subjects were coded and reimagined as colorful cityscapes based solely on their words to illustrate the unique body of knowledge readers would find within.
Boxes were drawn around each word of a title page and color-coded by its first letter (words beginning with “A” are one color, “B” another, and so on). Each title page has its own palette. Those boxes were then upended and arranged to form an abstract cityscape while maintaining their original sizes relative to each other.

A Book by Nicholas de MonchauxLocal Code’s data-driven layout arranges drawings of 3,659 digitally tailored interventions for vacant public land in San Francisco, Los Angeles, New York City, and Venice, Italy. The natures of these found parcels is as particular as the cities that house them — land under billboards in Los Angeles, dead-end alleys in San Francisco, city-owned vacant lots in New York City, and abandoned islands in the Venetian lagoon — but have in common an unrecognized potential as a social and ecological resource.
Urban Street Network Orientation
An Article by Geoff BoeingThis study measures the entropy (or disordered-ness) of street bearings in each street network, along with each city’s typical street segment length, average circuity, average node degree, and the network’s proportions of four-way intersections and dead-ends. It also develops a new indicator of orientation-order that quantifies how a city’s street network follows the geometric ordering logic of a single grid. These indicators, taken in concert, reveal the extent and nuance of the grid.

Infrastructure: A Guide to the Industrial Landscape
Savage, hostile, and cruel
Some may find puzzling or distasteful the parallel I am drawing between the study of nature and the study of technology. After all, nature is good and good for you, whereas everyone knows that technology is ugly, evil, and dangerous.
A few centuries ago—say, on the American western frontier—a quite different view prevailed. Nature was seen as savage, hostile, cruel. Mountains and forests were barriers, not refuges. The lights of civilization were a comforting sight. We took our charter from the book of Genesis, which grants mankind dominion over the beasts, and felt it was both our entitlement and our duty to tame the wilderness, fell the trees, plow the land, and dam the rivers.
Nature undisturbed
My chief aim is simply to describe and explain the technological fabric of society, not to judge whether it is good or bad, beautiful or ugly. And yet I would not argue that technology is neutral or value-free. Quite the contrary: I suggest that the signs of human presence are the only elements of the landscape that have and moral or aesthetic significance at all. In nature undisturbed, a desert is not better or worse than a forest or a swamp; there is simply no scale on which to rank such things unless it is a human scale of utility or beauty. Only when people intervene in nature is there any question of right or wrong, better or worse.
The raw materials of society
A big hole in the ground: This is where most of the raw materials of an industrial society come from. To appreciate the scale of this excavation, note that the bright blue object on a shelf near the center of the image is a Porta Potti.
The dragline
A dragline is the largest of the machines used to strip away the overburden and mine the ore layer at an open-cast mine. A bucketload for this particular dragline, one of the world's largest, is 220 cubic yards. Note the school bus, which would easily fit in the bucket.
Dark satanic steel
When poet William Blake wrote of "dark satanic mills", he couldn't have been looking at a steel mill because there were none in 1804. Nevertheless, when I visit a steel mill, Blake's phrase always comes to mind. With the heat and the pounding noise, the dust and smoke, and the red glow against the night sky, it's hard not to see these places as infernal. And yet the process of making steel also produces some of the most hauntingly beautiful images found anywhere in the world of industry.
Strength from both mass and form
Hoover Dam has the shape of an arch dam, but it is actually a hybrid structure, gathering strength from both mass and form. The dam is often ranked as one of the most exquisite of all engineered structures. It is fitted to its site so well that the gnarly canyon wall looks like an organic growth engulfing the mass of concrete.
Warmed by the afternoon sun
Textbooks on water-system engineering state that supply mains are generally installed on the north side of the street in the Northern Hemisphere and on the south side in the Southern Hemisphere, so that the sun will warm them. In both hemispheres they are supposed to be on the east side of north-south streets, on the premise that the afternoon sun is warmer than the morning sun.
Trompe l'oeil fantasies
In residential neighborhoods some sewage-pumping stations are trompe l'oeil fantasies, dressed up to look like the split-level or colonial houses that surround them. If you look closely, it's not hard to spot these disguised pumphouses: the heavy-duty power connections, the big ventilating fans, and the diesel generator in the backyard are all tip-offs. Furthermore, the windows are often fakes, with sash and shutters adorning a blank wall.
Quaker Square Inn
The modernist architect Le Corbusier was an admirer of American grain elevators, suggesting that their regularity and modularity could serve as a model for other kinds of buildings. At least one later architect took the suggestion seriously. The Quaker Square Inn in Akron, Ohio, occupies the shell of a former elevator. If you're in town for the night, you can rent a round room in one of the silos.
A metropolis for hydrocarbons
An oil refinery suggests the image of a metropolis for hydrocarbons, the pipe manifolds like expressways, the distillation towers like skyscrapers.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Pylons
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
The Iridium System
Several Low-Earth-Orbit (LEO) networks were proposed, but only one got off the ground: the Iridium system. The original Iridium proposal called for a "constellation" of 77 satellites, which gave the plan its name: the element iridium has atomic number 77, meaning that an iridium atom has 77 orbiting electrons. Before the satellites were launched, the constellation was scaled back to 66 active satellites, but no one wanted to change the name to Dysprosium.
Roads to nowhere
Among real-estate developers, straight lines and right angles went out of fashion sometime in the middle of the twentieth century. If you look at a town or a residential neighborhood laid out since then, you are more likely to find sinuous, serpentine roads—whether or not the topography offers any excuse for such curves. Many of these roads go nowhere: they are loops that bring you back to where you started, or they are cul-de-sacs. Making it easy to find your way through the network of streets is obviously not a high priority. This is an interesting development in urban geography: having redesigned the city to accommodate the automobile, we now search for ways to discourage people from driving on the streets.
A gradual refinement
The steel rail is an artifact whose form has been carefully optimized. This gradual refinement of the design was done not by a single brilliant engineer but by more than a century of industrial evolution. The rail was never meant to be an object of beauty, but its cross section has all the elegance of fine typography.
Hyperart: U.S. Rail
The steepest grade on U.S. main-line track is at the small town of Saluda, on a Norfolk Southern route between Spartanburg, South Carolina, and Asheville, North Carolina. The grade goes on for three miles at a slope of 4 or 5 percent. Trains have not been running on the line since 2001, but the tracks are still maintained.
An emblem of friendship
Bridges make connections; they bring people together—a role that has made them a traditional emblem of friendship. Consider the town of Mostar in Bosnia-Herzegovina. When fighting between ethnic factions broke out there in the 1990s, nothing symbolized the social disintegration more clearly than the destruction of a sixteenth-century stone-arch bridge that had linked the two parts of the town on opposite banks of the Neretva River. And the emblem of efforts to heal the divisions is a rebuilt bridge, opened with fireworks and fanfare in July of 2004.
Routine design
When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art.
The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.
No Smoking
What's that big electrical cord that also connects the ship to the dock? It's not a power cord to run machinery aboard ship; it's a grounding strap, to prevent sparks from static electricity. Something else you're sure to notice on a tanker is a big warning sign about the fire hazard. Frederick Allen, the editor of American Heritage of Invention & Technology, has remarked that all tankers seem to be named No Smoking.
Port furniture
All the miscellaneous fittings and fixtures on wharves and piers and elsewhere in nautical neighborhoods are known by the charming term port furniture.
The mirror-image economy
When we enter the world of refuse and waste, we cross over into a mirror-image economy. In the "normal" world, we pay to acquire things; on the other side of the looking glass, we pay to get rid of them. Junk isn't merely worthless; it has negative value.
A chemical engineer once told me about a recent improvement in a manufacturing process; by fine-tuning a chemical synthesis he had increased the yield of a certain commodity from 98 percent to 99 percent. I congratulated him, but I couldn't help remarking that this seemed like a rather paltry improvement. "Ah, you miss the important point," he said. "The amount of waste goes from 2 percent down to 1 percent. It's cut in half. We save tremendously on disposal costs."
NIMBY, BANANA, NOPE
Waste-disposal facilities of all kinds—landfills, incinerators, even transfer stations—are sure bets for generating the NIMBY response: not in my backyard. In its most cynical form, NIMBY is the attitude of citizens who acknowledge the need for a facility, somewhere, but who oppose a plan for building it simply because the selected site is too close to their own property. But opposition to landfills and many other kinds of development goes well beyond cynical NIMBY. Another catch phrase for this phenomenon is BANANA: build absolutely nothing anywhere near anybody. Or else it's NOPE: not on planet earth.
Creations of human artifice
In the twenty-first century, the question most of us ask when disaster strikes is not "How could God let that happen?" but "Who screwed up?" This is a salutary development: We take responsibility for the world we live in. Whether or not our world is the best of all possible worlds, it is a world we have made for ourselves. We live in an engineered landscape, on an engineered planet. Our cities and farms, our dwellings and vehicles, our power plans and communication networks—these are all creations of human artifice. If we don't like it here, we have only ourselves to blame.
What kind of world it's going to be
The wonderful thing about living in a world of our own creation is that we get to choose what kind of world it's going to be—at least in principle. But the promise is meaningful only if a broad enough "we" can be engaged in the process. At present, mechanisms and democratic institutions for making collective decisions about the deployment of technology are hopelessly cumbersome. How can anyone make a sensible choice without being able to weigh one alternative against another?
