Consensus and Vision

The death of Steve Jobs has led to impromptu discussions about the nature of his genius, causing some to call for a Steve Jobs of transit. Human Transit quotes such calls in comments and tries to strike a balance between good organization and singular vision; Market Urbanism tweets that it’s impossible only because of public control.

Instead of this fantasy for someone who will have enough power to make transit great, let us step back and ask what makes transit cities work. It’s not really vision – the inventions that have made transit more useful in the last few decades (for example, the takt and the integrated timetable) are so distributed that it’s impossible to assign them a single inventor or even agency. And in the US, the last true visionary of urban transportation, Robert Moses, had about the same effect on the city he ruled that such visionaries as Stalin and Mao had over their countries.

The absolute worst quote one can invoke in the field is Henry Ford’s apocryphal claim that if he’d asked customers what they’d wanted, they’d have said faster horses; Ford may never have said that, but he believed something along these lines, and as a result lost the market to General Motors in the 1920s. People tend to project the same attitude, with far more success, to Steve Jobs: he saved Apple from ruin when he came back, he saw potential in Xerox’s computers that nobody else did, he focused on great design above all. Some of this is due to the cult of personality Jobs created around himself, unparalleled in the industry; a better assessment of Apple’s early growth comes from Malcolm Gladwell, who dispenses with Great Man histories and talks about innovation as an incremental process requiring multiple different business cultures to get anywhere.

In cities, there really is a need for consensus rather than autocratic vision. The reason Moses was so bad for New York is not just that he happened to be wrong about how cities should look. Roads were not his only sin, and on one account, the use of tolls, he was better than the national road builders. No; he reigned over a city that to him existed only on maps and in models, routing expressways through blocks with the wrong ethnic mix and depriving neighborhoods of amenities in retribution for not being able to complete his plans. Because he was insulated from anyone who could tell him what the effect of his policies was, and had no effective opposition, he could steamroll over just anyone.

The reality is that any Steve Jobs-like autocrat is going to act the same. Moses did it; Janette Sadik-Khan is doing it, delaying even popular projects in Upper Manhattan because of the perception that it’s against livability; Jaime Lerner did it, moving pollution from Curitiba to its suburbs and slowing but not preventing the spread of cars. In contrast, Jane Jacobs’ own observations of her struggle are the opposite, focusing on consensus and participation and crediting “hundreds of people” with saving the West Village. Everything I said about consensus and cities and about democratic consensus applies here.

The same is by and large true of transit. Although the subject is more technical, the role of experts is similar to their role in urbanism: answering narrow technical questions (“does the soil allow this building type to be built?”, “how much will it cost to run trains faster?”), helping people see tradeoffs and make their own choices, bringing up foreign examples that local activists may not be familiar with. They’re just one of several interest groups that have to be heard.

I think people who ascribe invention to great individuals finding things consumers didn’t even know they wanted are projecting the history of the 19th century to present times. At the time, invention was done individually, often by people without formal education. It was already fairly incremental, but much less so than today, and was portrayed as even less incremental since to get a patent approved the inventor had to play up his own role and denigrate previous innovations. Since it was not done in the context of large companies or universities, the corporate culture issue that Gladwell focuses on didn’t apply. The economy, too, was understood as a process involving discrete inventions, rather than a constant rate of growth, as Andrew Odlyzko’s monograph on the Railway Mania discusses in chapter 15.

We no longer live in such a world. Fixed-route public transportation has existed since the 1820s. Practically all innovations within transit since have been slow, continuous improvements, done by large groups of people or by many individuals working independently. Even implementations of previous ideas that became wildly successful are rarely the heroic fit of a mastermind. The few cases that are, such as Jaime Lerner’s dirt-cheap BRT, indeed spawn rants about democratic consensus and raves about vision and fast decisions.

In contrast, I do not see any mention in mainstream US media of the role of Swiss consensus politics in the backing of the Gotthard Base Tunnel or in SBB’s 50% over-the-decade growth in passenger rail traffic. If there’s a story about Tokyo or Hong Kong, it’ll be about skyscrapers and development, not about their collective decisions to restrain car traffic while rapid transit was still in development. And while China’s rapid expansion of transit and high-speed rail, at much lower cost than in the US, has gotten much media coverage, scant attention has been paid to Spain even though its costs are lower and its expansion is nearly as rapid.

What’s happening is that people imagine single heroes to do what is really the work of many. Alternatively, they romanticize autocrats, even ones who were unmitigated disasters, such as Moses. Even stories about consensus and social movements get rewritten as stories about great people, for example Jane Jacobs, or more broadly Martin Luther King. It’s an aesthetic that treats everything as a story, and in the 19th century, it often was: in other words, it’s steampunk. The difference is that steampunk artists don’t wish to return to a world in which women have to wear corsets. And in similar vein, people who imagine benevolent, visionary dictators should not try to confuse their fiction with reality.

Aesthetics and Usability

New York is spending multiple billions of dollars on two signature projects in Lower Manhattan of which the more expensive (PATH terminal at $3.8 billion) has no transportation benefits and the less expensive (Fulton Street Transit Center at $1.4 billion) has small transportation benefits. This has led Stephen Smith and Ben Kabak to posit an opposition between spending on aesthetic design and spending on good transit, leading a few irate commenters to declare that they don’t like ugly transit and that design matters. In principle Stephen and Ben are right and the commenters are wrong, but the main issue involved is broader, and somewhat different.

The first observations I made of the photos Stephen provides is that the example he gives of ugly transit, Shinjuku Station, is in fact quite aesthetic. It has nothing on any average Mediterranean city, but neither does Grand Central. From the photos I’ve seen of Shinjuku, and my best recollection of staying one night in the area ten years ago, it looks fine from street level. The opposite is true of PATH’s Calatrava terminal, which looks like a monument to the architect more than a useful train station for ordinary passengers.

What passes for great design, in other words, is not based on normal street-level impressions. It’s based on how things look in drawings or aerial photos and on the ability of the project to act as a monument. Medieval cathedrals were designed to be big to make the individual feel small compared to the greatness of the institution that built them; the same is true of modern signature train stations and downtown revitalization skyscrapers. The Twin Towers were not designed for high office capacity; the commercial floor area ratio on the site of World Trade Center was 10, compared with 33 for the Empire State Building. They were designed for urban renewal, and thus looked much better from the air than from the ground; the same is true of the Calatrava terminal.

More in general, this relates to what I said about London and how it looks better on a map than on street level. This is less about aesthetics and more about usability, but the general argument is the same.

Grids, clockface schedules, and simple fare systems all have this benefit that occasional users, or regular users going outside their usual train line or neighborhood, can easily grasp what is going on. Living in ungridded Tel Aviv, I knew how my own neighborhood’s street network looked like; similarly, a colleague who reverse commutes from Boston knows the timetable of the trains useful to her. The supposedly beautiful schedules or street networks that planners come up with aren’t as usable.

The conflation of usability and aesthetics can easily lead people to think that spending billions on an iconic train station has any benefit except to Calatrava and his company. A commenter on Second Avenue Sagas even mentioned Apple as an example of design-based success. In reality, the iPod is easier to browse than any MP3 player that came before it, leading to success at a time when Apple’s brand was in the gutter; and unlike the BlackBerry that it displaced, the iPhone has games and customizable apps and a touchscreen that everyone other than me seems to like. It’s those devices that form Apple’s core product, measured by operating income; the Mac, which is based purely on design and brand, is a niche.

So the question is what usability-oriented spending could have been done in Lower Manhattan. This is of course purely academic. Like the original World Trade Center, those post-9/11 projects have never been about the needs of users, or even about simple aesthetics; they’ve always been about agency self-aggrandizing. But for $5.2 billion, they could have done a lot to build a Hoboken-Fulton Street-Flatbush tunnel and run RER-style service (at European construction costs, they could’ve built the entire tunnel and had change to spare; at New York construction costs, probably not). They could’ve integrated the fares between PATH and the subway, instead of having each agency seek an incompatible smartcard standard (Cubic for PATH, the ISO standard for the MTA). Instead, they spent about a billion on improvements for pedestrian circulation at Fulton Street and burned the rest of the money on the altar of starchitect aesthetics.

Suburbanization of Poverty: What’s New?

The current trend toward suburbanization of poverty is worth examining. It is incontrovertible that on the whole, the American poor are moving to the suburbs. Simultaneously, city centers are gentrifying, seeing large increases in income, with an influx of rich and upper middle-class people. This could lead to a French-style geography in which the rich live in central cities and the poor outside them. It’s not my intention to doubt that this trend is happening; my question is whether it represents a break from the past.

On the one hand, the consequences of such a trend clearly do represent a break from the past. We’re already seeing demands from business-oriented groups for more transit investment, and a new focus on urbanism in elite magazines. However, this by itself does not mean that the reasons for this trend are at all new. In fact, in one way, we’ve really been seeing the same trend for fifty years, in which both the inner and the outer limits of poverty are pushed outward. What we saw last decade was just a tipping point in which the expansion of the gentrified core was by itself enough to offset the wealth loss coming from the expansion of the ghetto.

The best example for this is New York, whose regional income distribution is arguably more regularly donut-shaped than that of other Americans metro areas, with less of a favored/ill-favored quarter geography. Furthermore, in Manhattan, there is a sharp color line between the Upper East and West Sides and Harlem, which is relatively easy to discern if you’re a resident. Mad Men contains multiple citations establishing Manhattan north of 86th as a bad area, and based on the geography of the 1970s, Joel Garreau placed the boundary at East 86th and West 96th. By the 1990s, we see citations putting the line at West 110th Street; moreover the Upper West Side has joined up with Morningside Heights, itself gentrified, moving the color line up to about West 123rd. This is a decades-long trend, rather than a recent development. Conversely, the boundary between the poor South Bronx and the middle-class North Bronx has, too, moved north over the decades, and is still moving north as the black middle class leaves for greener pastures.

In general, a similar story played out in the first-ring suburbs of many Rust Belt cities, especially in ill-favored quarters: the places that people used to flee the city to are now cities that people flee.

This is not to say that nothing has changed. Harlem and the South Bronx of today are richer than Harlem and the South Bronx of 1980, leading some people to think that they (especially Harlem) have gentrified far more than they actually have. People are no longer abandoning the Bronx in droves. But in terms of relative geographical income across the metropolitan area, we’ve really just witnessed an expansion of the donut going back to at least the establishment of the first modern suburbs in Westchester and Long Island, nearly a hundred years ago.

What we see is therefore inconsistent with the usual story of suburbanization of poverty. The exurbs are not terribly rich, but the Rust Belt exurbs are a far cry from their housing bust-stricken Sunbelt counterparts. Poverty is suburbanizing from the inside out rather than from the outside in, just as wealth and the upwardly mobile middle class did fifty years ago.

Although this implies that suburbia is unsustainable, the way it implies it is different from the usual explanation. It’s not that the future is bad for low-density settlements and good for high-density ones. It’s that the American urban form and political geography, especially but not only in the suburbs, are fundamentally unsustainable, and require constant growth to persist. Greenfield sites have an inherent advantage with respect to pensions, debt, and fossilized community relations;the debt-fueled system of growth in the US encourages moving on to the next tract rather than maintaining what exists. Thus today’s boomburb is tomorrow’s decaying eyesore. This can only be countered in persistently favored quarters, but those by definition only hold a small proportion of the population; not everyone can live in the richest 15% of the region.

The thing to wonder then is not why suburbs are hollowing from the inside out, but why city centers are expanding and gentrifying so rapidly. One answer is that Jane Jacobs was right, and diverse city neighborhoods can resile from the shock of middle-class flight. Indeed, the only significant non-Jacobsian neighborhoods in the expanding cores tend to be projects, and those tend to significantly lag in gentrification (for example, see Stuyvesant Town – and that’s a project that was originally white-only, thus middle-class). On the other hand, the projects are protected by public ownership laws, regardless of urban form, so even if Jacobs was wrong, developers would only eye them after exhausting private buildings.

A second answer is that today’s gentrified cities are something like greenfield sites. It holds up well with the analogy between gentrification today and suburbanization a century ago. That said, this analogy is political and sociological rather than geographical or economic: cities still have to pay pensions, and the buildings that are now selling for a million dollars per apartment are often very old. On the third hand, the social networks of the newcomers are mostly independent from those of the older residents: for example, they rarely send their children to neighborhood public schools, or if they do, they organize a separate school in the same building as the established school; so on the social level they really are greenfield.

That said, in the future, the trend for suburbanization of poverty can accelerate and become different from what it has been since the 1940s, if it reinforces itself. Cities are getting closer to a tipping point of being richer than their suburbs, possibly even to the point of having better social services for the middle class. This is to some extent already occurring with crime, though we’ve seen an absolute decline more than a relative decline in central cities, and is occurring more slowly with schools. Although on the whole the trend among people who care about schools and crime is to move to the suburbs, if the suburbanization of poverty, coming about from movement of people with other concerns, gets to this tipping point, then a large mass of people will abandon much of suburbia in favor of the cities, as urbanist common wisdom holds that they already are.

At least, they will try. The number of people who can live in a city is bounded by the product of household size and the number of available housing units, and the number of available housing units grows glacially in brownfield sites. Here, gentrified cities cannot imitate the properties of greenfield exurbs. As a result, we can expect to see an acceleration of the current trend of demand for cities translating into high housing prices rather than population growth. In such a scenario, cities will not become middle-class, but rather turn into enclaves of the rich and upper middle class. Of course there’s a natural limit on how high rents can go, especially in New York, Chicago, and other cities with large city proper populations, allowing the middle class to be comfortable in their suburban neighborhoods. But a transition to a French urban geography will be very rapid and self-reinforcing, and the rents will take every penny the upper middle class can afford.

Pedestrian Observations from Central London

As I got off the Underground, I was greeted by a fenced roadway without easy crossings. I found the way around a roundabout and started to walk toward the hotel where I was to meet my family, on the wrong side of the street. Although traffic was relatively light and the street was not very wide by New York standards, a fenced median required me to cross at one crosswalk, a Z-crossing with beg buttons and different pedestrian signal phasing for the two halves of the road. About five minutes after I first emerged above ground in London on foot, I realized: this city hates pedestrians.

Of course, the 20 mph zones, the naked streets, and the streets that are officially neither 20 mph nor naked but so narrow they might as well be are not, by themselves, hateful toward pedestrians. They’re rather pleasant. Even when they have beg buttons, which is often, those buttons can be ignored, as they routinely are in Providence. Beyond them, there’s a class of streets of about the same width as Manhattan streets, for example Portobello, which are busy and pedestrian-scaled. The issue is that the wider ones, the main streets, have completely abandoned any attempt at catering to pedestrians; they’re run by road engineers rather than by urban designers.

The failure of London is not a matter of preferring cars to cities, as is the case in American cities. The London Underground is quite nice, though it’s more because it charges exorbitant fares (see page 45 here, and realize that the graph seems to use a depreciated pound:Euro exchange rate) than because it’s particularly well-run. The commuter rail system is treated like modern rapid transit and is treated with lavish investment. There is an extensive bike share system, but with substandard bike lanes that tend to disappear into bus stops. None of this comes from a deliberate attempt to destroy alternative transportation; it’s just an unintended consequence of modernist planning.

In the view of the modernist planner, pedestrians and cars should always be strictly separated with fences if necessary, all crosswalks must be signalized, and it should be impossible to have any spontaneous crossings, or spontaneous anything for that matter. Ideally, crossings should be in pedestrian underpasses or overpasses, to eliminate all conflict. There can be delineated zones for pedestrians – side streets or some busy pedestrian malls, such as Covent Garden – but those should be placed away from the main streets.

In contrast, New York and Paris do things differently. Streets are wider both on average and at the minimum. Parking is done on the street, providing a buffer from traffic that’s wide enough to make me feel protected but porous enough that I can cross when I want to. Sidewalks are wide, crosswalks are frequent and let pedestrians cross in just one cycle, and increasingly protected bike lanes are cannibalizing road space that used to belong to cars. Of course, London’s main streets are wide enough that they could look like the delightful mess that is First Avenue if TfL wanted to. At a few places, they do look like New York streets, such as the aforementioned Portobello Road, with parked cars on one side. But for the most part, London treats its main streets, where most activity is, as arterial roads for cars.

This contrast between New York and London’s style of planning is jarring. New York’s grids are meticulously planned, without much variation except in the parts of Brooklyn and Queens where two separate grids meet. London is nothing like that – its street network is famously labyrinthine, and walking there with one’s roaming function turned off in order to save money requires hopping from one public map to another. But on the level of the individual street, this situation is reversed: London’s streets are meticulously traffic-engineered, while New York’s avenues are chaotic. It’s true even on the level of stereotypical cabbie behavior: for one, London’s cab drivers tend to obey traffic laws.

More fundamentally, it shows just why car-centric planning is so incompatible with urbanism: it tries to impose order on something that resists it. According to Christopher Alexander and the rest of the traditional urbanists, I’m supposed to shun the mechanistic design of New York (or Paris, which is as planned) and gravitate toward the traditionalism of London. In reality, my reaction is the exact opposite – on the micro level, New York is much more emergent and chaotic, and, at the level that is relevant to a local who doesn’t feel the need to constantly look up, vastly more human-scaled. London may appear to succeed on grand urban design principles on a map and in diagrams, but on little things that matter, it fails. It may have little pockets of success, and enough activity on the streets that I’m willing to spend 3 minutes crossing them when necessary, but it has nothing on its peer Western megacities.

That is not to say I avoided walking around London. On the contrary, I explored Central London during what little time I had to ditch my family. But the streets were not particularly inviting, and at some points it felt more like an adventure than like an ordinary walking trip. This never happened to me in New York or Paris or the (very few) other cities I’ve found to be walkable.

Who’s Migrating to the Sunbelt?

It’s well-known that people have been moving from coastal US states to the Sunbelt for many years now. But who’s moving? Is it the upper middle class fleeing higher taxes or searching for cheaper houses, or perhaps the poor fleeing high costs of living? Put another way, is the above-average growth in per capita income in many Northeastern and West Coast metropolitan areas a matter of actual growth, or simply of pushing the poor out to the Sunbelt, whose per-capita income growth is often anemic?

All data in this post is courtesy of Aaron Renn’s Telestrian service, which cribs numbers from the IRS, Census Bureau, and other sources and presents them in a reasonably searchable manner. The IRS keeps track of intranational migration in the form of tax exemptions, which allows us to figure out the migration trends in terms of people (exemptions), households (returns), and income (adjusted gross income). This way we can figure out if the people moving out of a region are richer or poorer than the average. Although the IRS misses a lot of people and much income, it is still the best available source in the US for migration statistics. The more accurate American Community Survey tabulates very coarse migration statistics.

Observe also that the IRS data is given per year, which allows us to look at zoomed-in trends. For example, here is California’s migration with each state as well as the rest of the world from 2000 to 2009. Here is somewhat worse-presented data for New York State. It turns out that migration marginally increased California’s per capita income, and had practically no effect on New York’s; in other words, their growth is real, and doesn’t come from pushing the poor away.

More precisely, we have the following observations:

– In both California and New York, the difference in income between immigrants and emigrants is very small; immigrants are slightly richer in California, $27,098 vs. $26,209, and slightly poorer in New York, $29,876 vs. $30,810.

– Overall both immigrants and emigrants are slightly poorer than the statewide per capita income. However, the effect is very small: according to the IRS, California’s per capita income in 2009 was $28,569 and New York’s was $31,617. Were it not for migration – that is, if people had lived in 2009 where they’d lived in 2000 but still earned the same income – California’s per capita income would’ve been $28,243, i.e. 1% lower, and New York’s would’ve been $31,689, i.e. 0.1% higher.

– The richest migration occurs between high-cost coastal states, especially between New York and California, while migration between those states and the Sunbelt is much poorer.

– The poorest large group of immigrants in both states is international immigrants. In both cases they were about 9% of total immigrants, so they can’t have dominated the numbers too much. Thus Jane Jacobs’ story that great cities take in poor immigrants and churn out a middle class, considered on the state level, is only partially confirmed by this data.

– Emigration to the Sunbelt’s bubble states – from California to Arizona and Nevada and from New York to Florida – was predominantly a 2005-7 phenomenon, and decreased markedly after the bubble crashed.

– Emigration to other Sunbelt states was more of a mixed bag. Georgia and North Carolina, both partial bubble states, also look like partial bubble states in the migration numbers, with emigration from New York and California peaking in 2005-8, but less prominently than with the proper bubble states. Emigration from California to Texas looks like that to a bubble state, despite Texas’s strong economy through the recession; but emigration from New York to Texas and from both states to Colorado remains steady.

– The biggest difference between immigrants and emigrants is not income but household size – emigrating households were much bigger (1.95 vs. 1.7 in California), but still much smaller than the statewide average (2.23 according to the IRS, much lower than the actual average but comparable with the above numbers). This is only partially consistent with the explanation that those regions attract singles and DINKs and turn away families.

The story I started this investigation with is that New York and California predominantly turn away the middle class, which would be seen in middle-class emigration and low-income immigration; my recollection, coming from merely eyeballing the data, had been that immigrants were much poorer. This should be consistent with the breakdown of the cost of living in dense city regions: housing is unaffordable if your ideal of how to live is having a car and a single-family detached house that’s less than an hour away from work; if you’re flexible about car ownership and don’t mind small apartments, then New York and California are quite affordable.

But what we actually see is that both immigration and emigration between those states and the rest of the world is middle-class. The people moving to the Sunbelt really are being priced out. It’s hard to distinguish pricing out from cashing in on high housing prices, but the lower-income characteristic of this emigration suggests the former. The upshot is that policies reducing the cost of housing could stem this tide while at the same time having no effect on poverty and the need for social services. While it’s heinous to try to price out the poor, as the richer parts of the Bay Area and many other regions do, this is not what is being done here.

Let me close by linking without much comment to the same data for Texas. The IRS recorded a total income of $475,109,477 in 2009 and a total population of 19,235,926, i.e. a per capita income of $24,699. As in California, immigrants are a little poorer than emigrants and both are a little poorer than the average. Controlling for this effect as above would raise per capita income to $25,002, a 1.2% rise.

The Rail-Trail Scam

I recently learned that a writer for the Adirondack Explorer has the following proposal to create a new rail-trail: demolish a line that’s in use by a heritage railroad, pave it over, and convert it to a bicycle trail. The arguments in the piece are your standard hatchet job considering only the costs of rail and only the benefits of the alternative, and are downright uninteresting; what’s interesting is that this is just the culmination of the misuse of the original concept of rail-trails.

Originally, rail-trails were created to preserve railroads for future use. Their mandate includes “to preserve established railroad rights-of-way for future reactivation of rail service.” In reality, restoration almost never happens. The Rails-to-Trails Conservancy’s review of railbanking points to success that a full nine railbanked corridors have had rail service restored, out of 301. The rest have been paved over, and often have enough non-railroad users that any restoration would be politically difficult in practice; I suspect that this is why the Providence Foundation makes no mention of restoring service on the second, now-abandoned track between Providence and Woonsocket in its regional rail study.

Another problem with railbanking is that it focuses on what’s useful as a trail, and not on what would be useful as a railroad later. There are pleasant exceptions, such as the Milwaukee Railroad’s route in most of Washington State, but in Rhode Island, the rights-of-way that have been preserved are those that would be easiest and least expensive to rebuild from scratch: the line to Hartford through West Warwick and Coventry, the line from East Providence to Bristol, and the aforementioned second track to Woonsocket. In contrast, many major pieces of infrastructure were demolished. Downtown Providence’s connection to East Providence was cut and would require new urban viaducts to be restored, and it’s sheer luck that the bridge over the Blackstone estuary is still there. Newport’s only rail connection to the mainline was railbanked but removed, which means restoration would face fewer regulations than starting new service from scratch, but only after rebuilding a bridge from the island to the mainland.

This is not intentional, but it’s neglectful of the needs of any mode other than the car as regular transportation; even bikes only get the nod for recreational use. The document coming out of Rails-to-Trails Conservancy, Railbanking and Rail-Trails: a Legacy for the Future, makes this thinking clear, when one reads between the lines. Here are some touted benefits of rail-trails:

The USDA’s Dietary Guidelines recommend at least 60 minutes of daily exercise for children and teens and at least 30-60 minutes everyday for adults. Trails provide close, safe, traffic-free paths for walkers, joggers, inline skaters [and] cyclists. Rail-trails are also part of a nationwide initiative launched by Congressman James L. Oberstar (D.-Minn.) to create safe routes that will encourage school children to walk and bike to school.

The first sign of utter disregard for alternative transportation as everyday transportation is the touting of “traffic-free paths.” Segregation of different modes of travel into different rights-of-way is the thinking of the traffic engineer and the freeway builder, not of the urbanist. The second is the fact that, in practice, the placement of those trails follows ideal corridors for the needs of trains, not bicycles or pedestrians. One does not use a mode of transportation that averages 60 km/h and loses 2 minutes every time it stops the same way one uses a mode that averages 25 km/h and can stop where you want. You can look at the northern end of the aforementioned West Warwick trail on Streetsview or on satellite and judge for yourself how useful it is for a cyclist’s daily work trip; a train would just blast through at full speed.

There’s already an ideal place for pedestrians are cyclists: the streets. Those are the strange linear alignments used by cars and fronted by actual residences and jobs. Away from urban areas, those are the country roads that go through small towns. A policy that aimed at reducing car use and getting people to use more active transportation would impose walkability and bikability standards on streets, which are where the exact addresses people want to go to are. A policy that didn’t care would turn railroads into recreational trails and greenwash it by saying they’re usable by pedestrians and cyclists. And I think we all know which of the two the rail-trail scam is.

Consensus and Cities

Note: this is the first post in a series of 3-4 articles about consensus urbanism.

The dominant discourse on cities nowadays focuses on the role of visionary, top-down innovation. Some write about mayors who change paradigms, such as Michael Bloomberg and now Rahm Emanuel. Others write about entrepreneurs and the role of new technology, and invariably portray the change as groundbreaking and unforeseen by all except the dogged inventor. In contrast to this worldview, let me propose a view of urbanism based on political consensus among disparate interests, on forging agreement instead of trying to defeat everyone else.

The current trend toward livable cities, as seen in road diets and bike lane projects, is entirely top-driven. Bloomberg decided to make it his legacy, and Transportation Commissioner Janette Sadik-Khan moves aggressively with little consultation with community interests except those that already agree with her. Rahm Emanuel, infamous for his combative style, followed suit. This caused livable streets advocates, led by Streetsblog, to often identify community consensus with NIMBYism and top-down change with improvement; it’s unavoidable on Streetsblog, though sometimes there are glimpses of support for a more consensus-based policy on other livable streets blogs.

In reality, in cities, there are too many interest groups for one to normally dominate: labor, the middle class, multiple kinds of business, organized religion – and in the exceptional cases, such as Singapore, it comes out of autocracy. This is especially true in the US, with its multi-ethnic cities, requiring delicate acts of ticket-balancing. This is easy to paper over in majoritarian political systems, as the US is, but the actual practice of politics in American cities is far from majoritarian. Liberal cities have become cities of primaries – one wins by assembling an ad hoc coalition that can win the Democratic primary. In general, cities have multiple interest groups, even independently of ethnicity: see for example Christof Spieler’s analysis of the 2009 Houston mayoral race. The reason this political process hasn’t led to a consensus-based decision making is that the electoral process – in particular, the authoritarian strong-mayor system – is anti-consensus.

And yet, a consensus-based agenda is possible. As one of the Streetsblog community members explained to me, the way to obtain community support for a project is to talk to all stakeholders in the neighborhood, and understand what their hidden hopes and fears are; it’s important to avoid any situation in which someone later complains “Nobody informed me about this.” Ordinary people are far less intransigent than they can appear in the papers. For example, along Queens Boulevard, the long-term residents are still reeling from plans to turn the street into an expressway, and therefore will support or oppose a livable streets proposal in part based on whether they perceive it as turning the street into more of a highway (closing cross-streets) or less of one (widening sidewalks).

A community so empowered with its own ideas about how to make itself pedestrian-friendlier will of course help if a top-down reformist politician wants to make the city more livable, but it can also convince an apathetic politician to champion its cause if it can demonstrate that this cause is popular. The same is true of many other public projects and contentious issues; support for many of them crosses ideological and partisan boundaries, both the normal national ones and the specific issue of machinists vs. reformists in American cities.

Consensus must be contrasted with its distant top-down cousin, outreach. Outreach is what a partisan or dominant side in a debate does to get the little fish on board. There’s almost no possibility of dialogue. In contrast, consensus implicitly assumes that all stakeholders own the decision, more or less equally even if one side began the push for it and in reality did most of the work. One can imagine a community board agreeing to a development plan put forth by a mayor, and then criticizing the mayor for it after it fails; one can’t imagine the same if the community board is the body that created the plan.

Film critic Pauline Kael, when asked to comment on why Nixon won the 1972 election, refused to comment, saying she couldn’t know because nobody she knew voted for him. (This has been misquoted in conservative circles as her saying that she couldn’t believe he could have won.) Kael’s contrition was unusual; most people are more than happy to generalize based on the few people they know who fit a type, or, even worse, based on stereotypes they’ve heard from others. It’s bad enough in a bipartisan world, but in city politics, the large number of different factions and worldviews is such that no one force can possibly know enough to govern for everyone.

Although the political process of any non-autocratic city forces some cooperation among groups, the practice can be authoritarian enough that many are completely unheard of in the halls of power. This is especially true of recent immigrants and others who have no long-term activist presence, or of racial minorities in cities with a majority race and racist politics. But even groups with some organization and voting power can be shut out by a Bloomberg, an Emanuel, or even a Villaraigosa. The result is that even policy that isn’t malevolent can be destructive; this is the sin of many postwar urban renewal programs, which didn’t have to accommodate the concerns of the neighborhoods they leveled and had no intention of listening to anyone they didn’t have to listen to.

The alternative is to embark on a process that’s slow, but more robust. It’s immune to changes in electoral fortunes, since swings from 52-48 to 48-52 don’t have such a huge impact on policy. The roads movement in the US got everything it wanted from the 1910s to the 1950s, from governing ideologies ranging from Hooverism to New Deal liberalism. It’s important to imitate this one aspect of the roads movement, and ensure as many groups as possible pull in the same direction.

There are always authoritarians-in-making, people who pay lip service to any consensual and democratic concept they need to be seen to support but in reality seek power for themselves and surround themselves with yes-men. Those we need to be watchful of, to make sure that they never have the power to cause permanent damage. Streetsblog has shown glimpses of holding the Bloomberg administration’s feet to the fire on issues on which the city has not been a positive force for livability – for example, the 1st/2nd Avenue bike lanes – but we need to do more than that, and ensure that even if an autocrat has power, we use him more than he uses us.

Switching from a fundamentally authoritarian booster mentality to consensus governance has no hope of getting us demolition of low-performing or city-splitting freeways, or Hong Kong-style traffic restraint, at least not until the far future. It will take a long time to overturn preexisting anti-urban biases – even longer than necessary, since it will be based on consultation with many groups that oppose gentrification and find what’s happening to American cities now a bad thing. It requires letting go of many proposals that are currently too expensive, and focusing on making the process friendlier to good transit and walkability and less so to boondoggles and pollution. It requires sitting down with people we may find abhorrent on other issues. Its saving grace is only that, in the medium and long runs, it works.

Pedestrian Observations from Barbados: Followup to Caribbean Car Ownership

The biggest criticism I’ve gotten in comments to Matt Yglesias’s link to my previous post was about my comparison of Puerto Rico’s car ownership with that of neighboring middle-income Caribbean nations. Multiple people claimed that Puerto Rico is much larger than the other countries and therefore needs cars, whereas in the rest of the countries people can walk everywhere. The correlation between size and car ownership is not statistically supported – whereas that with urban density is – but I’m going to instead narrate the pedestrian experience in Barbados to explain why positing such correlation doesn’t make sense. One commenter, Peter from the Block, writes:

Unless you are on a small island like Barbados or Antigua or Barbuda, in which case everything is close [enough to walk]!

My experience with Barbados comes from a week-long conference in Holetown last year. The conference was at the beginning of May, when the Sun came within two degrees of the zenith. The main road we’d use to get back and forth from the institute where we slept and the conference was held to the area where we could shop for food has little shade and even less tree coverage. The sidewalks are narrow, and there’s no real street wall: on the contrary, commercial buildings are fronted by parking lots. With the Sun directly overhead, the high asphalt coverage made for intense heat.

There was not much traffic by suburban American standards, but enough that it was still impossible to walk in the roadway, making the narrow sidewalks a problem whenever more than about 3 people walked together. In addition, the mall we used for food shopping is surrounded on all sides by parking, with a gas station on the side. My recollection of the people I saw in the area, including in the mall, is that they were mostly black, therefore majority-local (for while presumably there were some African-American tourists, most tourists would be white), but tourists comprised a disproportionate fraction.

For trips to other parts of the island, we got around with a tour bus rather than on foot. I tried at one point and failed to learn to use the local bus system and visit the main city, Bridgetown; walking would take far too long. The tour bus took us to a patch of rainforest and back, with a stopover at a beach; none of the points we passed in between looked especially dense, and few looked walkable.

Bear in mind, the above does not apply to Bridgetown. Purely from Google Maps tourism, it looks like a pedestrian-centric traditional city to me, of the kind that Charlie Gardner and Nathan Lewis would rave about. Presumably, car ownership is low because people in the cities can walk to their daily errands. But this is precisely the point I was making about the role of national policy in transportation mode choice: while Barbados’s size and national density are features of geography, the shape of its cities and its urban density are features of government policy.

Another thing one should note is that although walking to local errands was annoying, it was possible. This, again, is a feature of land use and transportation policy – probably inertia rather than a conscious choice, but still a different path from that taken by the US. Local travel is not that sensitive to national size and density.

Barbados is not Monaco. Its national population density, 660/km^2, is high by any global standard, but it’s not a high urban density. There are plenty of suburbs in New Jersey with several times that density where one could not walk to a supermarket. Under an American (or Malaysian) transportation policy, Barbados would’ve not only been pedestrian-hostile, but also sprawled like San Juan or Honolulu.

Where Did You Grow Up?

The last few weeks’ posts on Old Urbanist made me think about what urban forms people prefer, and how it’s affected by what they are familiar with. Rather than speculate on what people in my social circle prefer, I yield the stage to you. What type of urban environment did you grow up in, and/or influenced your thinking about cities the most? And what form of urban development do you find most desirable?

I’ll start: I grew up in the Old North of Tel Aviv, a dense (about 15,000/km^2) neighborhood whose residential stock is almost exclusively four-story Garden City apartment buildings. Buildings are not attached as rowhouses, but instead are set back a few meters from the edges of the lots; typical apartment size is 120 square meters. The neighborhood is upper middle class – indeed, North Tel Aviv is used as a metonym for latte liberalism – but is not uniformly so. Growing up, I knew plenty of people in the neighborhood who were middle middle class, a few who were working class, and a few who were outright rich. This somewhat distinguishes North Tel Aviv from some surrounding suburbs that are nominally equally rich but are more uniformly upper middle class. In the 1990s, it was also stable rather than gentrified; there were, and still are, people living in the same neighborhood, sometimes the same apartment, for multiple decades.

As a result, I never grew up with the association of detached houses with wealth. Hebrew even distinguishes words for houses in general (house/home) and words that denote wealth (villa, cottage) but has just one word normally for an apartment; English, which distinguishes an apartment or a tenement from a condo, is exactly the opposite. Having a car is important for social status in Israel, but the idea is to drive it a short distance to work, as my parents did. Driving 20 kilometers each way would be strange. At the same time, I took some measure of walkability for granted, making me uncomfortable with sections of the city that were built after the 1950s and were designed to automobile scale. I did not think of public transportation as a normal means of getting to work, unless one couldn’t afford a car, but it was nifty for getting to school.

The ideas about urbanism I’ve developed out of that experience, followed by Manhattan, are:

1. Street width should be close to building height; for the purposes of this discussion, street width is measured from building edge to building edge, and building height is the average height of the continuous street wall. A height:width ratio of about 1 or slightly higher is best. Below about 1/2, it’s too open; in Providence, where the ratio is about 0.6, measured from the top of buildings, I already walk in the middle of the roadway, as if the streets were naked. Above about 2, which exists on some streets in such pre-industrial cities as Florence, it feels like an alley. As a corollary, very narrow streets are suitable for low-traffic cities, whereas high-density places should look more like Manhattan.

2. Every normal neighborhood amenity should be reachable on foot, on streets that are designed to be used primarily by pedestrians. If you need to take mechanized transportation or cross a highway to get to the supermarket, there is something wrong with your neighborhood.

3. Bicycles are a form of private transportation.

4. Stoplight phasing is critical.

5. The street network should be porous. The closer to a regular grid, the better. The Old North has a grid of arterial streets, but the local streets terminate in T-shaped intersections, like this, and it’s not always possible to tell a local from an arterial street on sight; in addition, the grid is not really continued into other neighborhoods, making walking there confusing. I found Manhattan much more walkable than the Old North for this reason.

I will now exit the stage and make this an open mic.

Affordable Housing

A new post on Old Urbanist linking to prior posts about housing affordability, both on his own blog and on New World Economics. The theme is that various design standards – the two sites’ main scourge is streets wider than about 5-10 meters and in general excessive room for parking and front lawns – force the cost of construction up, making housing less affordable.

In reality, the first thing to note about high housing prices is that they exist everywhere: not just in new urbanist towns in the US, the type of development under discussion on the above blogs, but also in New York, and Paris, and Tokyo, and Tel Aviv, and Hong Kong, and London. In my matrix of different types of city planning, every row contains cities whose housing prices stretch the middle class to its limits. Often there’s significant homelessness, but most people have just enough to scrape by. The cities where housing prices are low compensate by either having very poor populations (inner-city Detroit) or requiring people to spend large quantities of money on driving (the Sunbelt): note how across US metro area, the total percentage of household income spent on housing and transportation is essentially constant.

Thus, as a first filter, the cities whose housing prices are low relative to incomes are very spread out and auto-oriented, exactly the opposite of any kind of urbanism other than suburbanism. As a second filter, Ed Glaeser notes that the high cost of housing in coastal cities comes from supply restrictions in the form of zoning, writing about Boston and about Manhattan as case studies.

First, what is clear about situations with unaffordable housing (really, barely-affordable) is that it is not due to high construction costs. Glaeser himself notes that construction of luxury apartments in Manhattan costs about $300 per ft^2, while the sales price per ft^2 is on average $600. In particular, parking requirements and other restrictions that effectively raise construction costs are not the primary agent to blame for high housing costs in general. An extra $20,000 for a parking spot is not going to make housing unaffordable, though it may influence developers’ decisions of what and where to build to maximize profits, in particular by making them abandon urban construction in favor of the suburbs. Glaeser blames persistently high housing prices on a regulatory tax, which forces developers to spend extra money on lobbying and preparing paperwork for permits.

Second, the primary determinant of housing prices is not capital costs, but the cost of the land underneath. An older post on Old Urbanist asks why real housing prices have increased since 1920; the answer is that a house is not a manufactured good, but primarily land, as is especially clear when one considers expensive, desirable cities.

Third, the worth of land is dependent on demand. Land on which a developer can build three apartments is worth three times as much as land on which a developer can build one apartment. That’s why on the level of the individual building, building higher does not reduce rents. Land supply only forms the limiting factor when there’s a regionwide desire to be in an area with a fixed land constraint, such as the national borders of Singapore or Monaco, or the physical extent of the New York City Subway or the walkable radius of Central Tel Aviv. In such cases, it could reduce prices to expand the available space for housing within the fixed constraint, via either increasing density or expanding the desirable area through transportation infrastructure or landfill. But otherwise, there’s not much point.

When high housing prices are genuinely the result of high capital cost, the result is different from that of high demand or a shortage of land. Consider North Tel Aviv, which mandates expensive whitewash on its traditional garden city buildings. When those buildings were first constructed in the 1930s, they were priced too steeply for the working class, leading the rising middle class to move in instead. Since the whitewash is also high-maintenance, apartments deteriorated, and the only buildings that maintain an aesthetic exterior cost much more to maintain and are only affordable to the rich. In effect, the result of high capital cost is worse physical stock, the opposite of what normally happens in Tokyo, New York, and other expensive cities.

Anti-gentrification activists often fight policies that make their areas more desirable; the above three points help explain why. Affordable housing to them is a bargain to richer people, and if they want to move in, they’ll be priced out. The only way to depress housing prices is to depress demand. One activist, a Harlem preacher with extreme right sympathies, even calls for a general economic boycott of his own neighborhood in order to cause an economic collapse and lower rents.

The inevitable conclusion, namely that it’s impossible to make housing persistently cheap without raising other costs or impoverishing people, does not mean that affordable housing issues are moot. First, the equity issue remains; although on average housing is just marginally affordable, to many people it is not affordable, and as a result, expensive cities engage in government intervention to prevent mass homelessness, even ultra-capitalist Singapore.

In addition, although expanding housing supply makes land more valuable and normally prevents prices from falling, it also create better housing in the process. Auto-oriented sprawl in the US has caused dwelling size to increase; upzoning and the construction of better transportation infrastructure in expensive cities would enable people to move from the periphery to the core – or, more precisely, people could stay where they are, but public transit could redefine regions from periphery to core.

For a toy model, suppose there are two kinds of development: regular suburbia and new urbanism, where new urbanism is more expensive. Constructing more new urbanism is going to reduce the price for both kinds of housing (new urbanism has an increase in supply, regular suburbia suffers from a subsequent decline in demand), while also shifting people from regular suburbia to new urbanism. Overall the average price of housing shouldn’t change, but the quality will increase.

In other words, on a national or regional level, affordable housing is never a problem; it may be a problem for poor people, but not in general, on average. Supply restrictions should show in low-quality housing, measured in terms of size, local walkability, aesthetics, and other factors that on the local level determine price.
