Using famous diagrams to explore the changes in urban planning

The San Francisco Planning and Urban Research Association has put together a new exhibit that provides an overview of urban planning. See 10 of the diagrams and short descriptions here. Also, here is a quick overview of the exhibit:

The exhibition’s title – Grand Reductions – suggests the simple illustration’s power to encapsulate complex ideas. And for that reason the medium has always been suited to the city, an intricate organism that has been re-imagined (with satellite towns! in rural grids! in megaregions!) by generations of architects, planners and idealists. In the urban context, diagrams can be powerful precisely because they make weighty questions of land use and design digestible in a single sweep of the eye. But as Le Corbusier’s plan illustrates, they can also seductively oversimplify the problems of cities. These 10 diagrams have been tremendously influential – not always for the good.

“The diagram can cut both ways: It can either be a distillation in the best sense of really taking a very complex set of issues and providing us with a very elegant communication of the solution,” Grant says. “Or it can artificially simplify something that actually needs to be complex.”

Over the years, some of these drawings have perhaps been taken too literally, while others likely lie behind some of your favorite spots in your city. “Even if you don’t know the diagram,” Grant says, “you might know the places that the diagram inspired.” SPUR shared these images from the exhibition, which opened this week. If you happen to live in San Francisco, you can also visit the show in person at the SPUR Urban Center Gallery (654 Mission Street) through February (oh, and it’s free!).

Three things strike me when looking at these influential diagrams:

1. On one hand, these diagrams are very similar to maps. On the other hand, they involve a particular vision that can sometimes be hard to achieve with a two dimensional image. These diagrams provide particular perspectives but they go beyond just being maps because the creators (and perhaps some of the viewers) can see a bigger picture.

2. They indicate a more scientific or rational approach to putting together cities. Particularly in the last century, urban planning has become a professional field that involves theories along with specific training and methods. These diagrams involve a lot of straight lines, overhead views, and the idea that the proper placement of buildings, streets, and other features can lead to the right outcomes.

3. These diagrams are quite artistic. Do they qualify as art?

How much does a 21st century city, like San Diego, need a catchy slogan?

A sociologist argues San Diego needs a new slogan for the 21st century:

“San Diego: First City of the 21st Century.”…

Industrial sociologist Walshok, whose book on San Diego as a center of innovation in science, technology and other sectors is due out next year from Stanford University, said this area has a public relations problem — no catchy “narrative” that sells.

“L.A. has the movies, San Francisco has the Gold Rush,” she said. “But I think our capacity to innovate and reinvent is our DNA. That’s what the community has been able to do in the 21st century. It isn’t a process that just happens in the lab. It’s in the ecology of the people, the neighborhoods, the diverse talent … ”

Walshok’s moniker recalls former Mayor Susan Golding’s formulation of a slogan coined in the 1990s, “San Diego: The First Great City of the 21st Century.”

While I get the idea behind the slogan, I’m not sure it really captures the idea of innovation and reinvention.

Looking beyond San Diego, is a slogan necessary for a 21st century city? Does it really encourage business growth from outsiders who see and like the slogan or is it more about people in a community developing a unifying theme that helps bring them together? I suspect it is more of the second. Slogans could help a city establish its own character and this is not unimportant. It might indicate that the local business community has banded together for booster purposes. It could reflect history and aspirations while also highlighting a strength that sets the city apart from other cities. Of course, slogans can be used for marketing purposes but it takes some time and sustained pressure for the concepts to sink in.

Here is a quick summary of a 2005 survey about city nicknames:

In 2005 the consultancy Tagline Guru conducted a small survey of professionals in the fields of branding, marketing, and advertising aimed at identifying the “best” U.S. city slogans and nicknames. Participants were asked to evaluate about 800 nicknames and 400 slogans, considering several criteria in their assessments. The assigned criteria were: whether the nickname or slogan expresses the “brand character, affinity, style, and personality” of the city, whether it “tells a story in a clever, fun, and memorable way,” uniqueness and originality, and whether it “inspires you to visit there, live there, or learn more.”

The top-ranked nickname in the survey was New York City’s “The Big Apple,” followed by “Sin City” (Las Vegas), “The Big Easy” (New Orleans), “Motor City” (Detroit), and “The Windy City” (Chicago). In addition to the number-two nickname, Las Vegas had the top-rated slogan: “What Happens Here, Stays Here.” The second- through fifth-place slogans were “So Very Virginia” (Charlottesville, Virginia), “Always Turned On” (Atlantic City, New Jersey), “Cleveland Rocks!” (Cleveland, Ohio), and “The Sweetest Place on Earth” (Hershey, Pennsylvania).

Outside of Las Vegas, aren’t the more informal nicknames on this list a lot more prominent than the official slogans?

Building more resilient cities

Constructing cities and social and political institutions that are resilient in response to disasters, like Hurricane Sandy, is not an easy task:

An article from The New York Times this past September explored New York City’s vulnerability from flooding, casting an eerie hindsight over this week’s storm. Dr. Klaus H. Jacob, a research scientist at Columbia University’s Earth Institute and an adviser to the city on climate change (also author of this predictive study), told the Times that subway tunnels would have flooded during Hurricane Irene had the storm surge been one foot higher. “We’ve been extremely lucky,” he told the paper. “I’m disappointed that the political process hasn’t recognized that we’re playing Russian roulette.” Today, repairs and service restoration are only just beginning in New York’s flooded subway system.

The opportunity is to rethink infrastructure in terms of resilience, and not just rebuild it as it was (as this post in Scientific American points out). As University of Toronto professor Christopher Kennedy points out in his important book on The Evolution of Great World Cities, the definition of infrastructure goes far beyond roads, airports, tunnels, rail systems, subways and bridges and includes the rules, code and norms which govern how cities are built. His research points out that London’s rise to global commercial dominance in the 17th century was fueled by its response to the catastrophic fires of 1666. These led to sweeping changes in the city’s building codes and widening of its streets, which in turn led to increased densities, the adoption of new building technologies, and ultimately remade the city in ways that put it on a new growth trajectory.
The roadblock to building resilient cities, quite simply, has less to do with science and more to do with institutions and politics, as Steve Nash pointed out a couple of years ago in The New Republic.

For one thing, the politics of sea-level rise are still hazy—no one seems to agree on whether it’s a local, state, or federal responsibility. And Congress is not doing much to resolve these issues. The climate bill that passed the House last year merely calls for more research, even though more blue-ribbon panels seem superfluous at this point. “Do you need cost-benefit analysis to know that you’re going to protect Manhattan?” asks [Jim Titus of the U.S. Environmental Protection Agency]. “That you’re not going to allow the Jefferson Memorial to go underwater? That Miami is going to continue to exist?” Those aren’t trick questions. But, for now, they’re going unanswered.

In other words, it isn’t just about rebuilding the same thing over and over again. Cities, and countries, need to develop plans by which the new construction is better suited to possible future disasters. The response to massive fires is cited above (and it reminds me of the changes in building after the Chicago Fire in 1871) but this has also occurred in response to earthquakes by setting codes so that buildings are better suited to face future threats. And being able to develop forward-thinking plans requires more flexible institutions that can respond to whatever changes come along. What worked in the past won’t necessarily work in the future so only changing after a major event or disaster is not a good thing. At the same time, such major events also may allow for a more sweeping reaction and change to take place in cities.

Seeing low-density Nashville as well as its revived core on TV

Nashville may be about country music but it also provides some views of sprawling Nashville:

Nashville remains one of the lowest density cities in the United States, and both film and series rove widely over its suburban homes and scattered music venues. ABC’s principle location, the Bluebird Cafe, occupies a strip mall in traffic-snarled Green Hills, surrounded by chain retail and McMansions. Reyna James lives in snobbish Beale Meade, a former plantation turned moneyed bastion that pointedly excluded the music community in the 1970s. Then country was considered the music of loud and ugly bumpkins. But as legendary Nashville producer Tony Brown observes: “Money can kinda pretty you up.”

Sprawl now competes with new urban designs in Nashville. Employing soaring aerial views, the series’ opening sequence scans acres of wooded hills and pasture, within which are carved oases of development, including the Opryland Hotel, the Mall in Green Hills and the Belle Meade estates. But no longer is Nashville a city without a center. The camera circles the downtown’s middling skyscrapers, zeroing in on Nashville’s resuscitated heart, the 120 year-old Ryman Auditorium, a former tabernacle and “the Mother Church of Country Music.”

The rest of the article provides some interesting insight into how Nashville has been viewed in movies and on TV.

One thought while reading about the changes in Nashville and how it is portrayed on Nashville: TV and movies tend to show the “high points” of urban and suburban life. In other words, we tend to get sweeping shots of urban cores that show off tall buildings and lights. When showing suburbs, we tend to see big houses and well-kept lawns. Both sets of images tend to promote a more glitzy image. What we tend not to see is the more mundane aspects of suburban and urban life. In the suburbs, you don’t see much of the big box stores or strip malls or fast food joints or local institutions like churches, schools, and civic buildings. (I’m also thinking here of Modern Family – we don’t see much of their actual community as most of the action takes place inside of several large houses.) In the city, we don’t see “normal” neighborhoods but tend to see neighborhood hangouts, which always tend to look like nice bars or coffee shops, as well as cool apartments or condos. Perhaps “normal life” is too boring for these story lines but movies and TV shows aren’t exactly providing an honest image of places.

Argument: Phoenix is world’s least sustainable city

I recently ran into an overview of a 2011 look at Phoenix as the “world’s least sustainable city”:

Phoenix, Arizona is one of America’s fastest growing metropolitan regions. It is also its least sustainable one, sprawling over a thousand square miles, with a population of four and a half million, minimal rainfall, scorching heat, and an insatiable appetite for unrestrained growth and unrestricted property rights.

In Bird on Fire, eminent social and cultural analyst Andrew Ross focuses on the prospects for sustainability in Phoenix–a city in the bull’s eye of global warming–and also the obstacles that stand in the way. Most authors writing on sustainable cities look at places like Portland, Seattle, and New York that have excellent public transit systems and relatively high density. But Ross contends that if we can’t change the game in fast-growing, low-density cities like Phoenix, the whole movement has a major problem. Drawing on interviews with 200 influential residents–from state legislators, urban planners, developers, and green business advocates to civil rights champions, energy lobbyists, solar entrepreneurs, and community activists–Ross argues that if Phoenix is ever to become sustainable, it will occur more through political and social change than through technological fixes. Ross explains how Arizona’s increasingly xenophobic immigration laws, science-denying legislature, and growth-at-all-costs business ethic have perpetuated social injustice and environmental degradation. But he also highlights the positive changes happening in Phoenix, in particular the Gila River Indian Community’s successful struggle to win back its water rights, potentially shifting resources away from new housing developments to producing healthy local food for the people of the Phoenix Basin. Ross argues that this victory may serve as a new model for how green democracy can work, redressing the claims of those who have been aggrieved in a way that creates long-term benefits for all.

Since the population of the United States has shifted in recent decades to Sunbelt cities like Phoenix, tackling sustainability in these more sprawling and hot places seems like it is important. I wonder how much this sustainability push would require curbing sprawl and if there are some critics who would argue places like Phoenix (or even the metropolitan regions of cities like Chicago and New York) can’t really be sustainable unless they severely limit sprawl.

In two trips to Las Vegas in recent years, I was struck each time by the landscape when flying into the city. I always enjoy seeing cities from above but Las Vegas (and presumably Phoenix as well) shows stark contrasts between deserts which suddenly turn into subdivisions, lawns, golf courses, and then opulent casinos. It is a quick reminder that some of these Sunbelt cities are carved out of the desert and this requires a lot of resources to maintain and expand.

More evidence of a racist North: disparities in incarceration rates by race existed in late 1800s

There is a disparity across racial groups in incarceration rates in the United States today. But this is not a recent phenomenon: a recently published sociological study argues this dates back to the late 1800s.

Since 1970, the percentage of Americans in prison has skyrocketed; the incarceration rate is especially pronounced among blacks. Though it’s often assumed that the racial disparity came along with the surge in incarceration, a recent study by a sociologist at Harvard suggests that the disparity originated earlier, with the emigration of blacks from the South. Not only was the racial disparity in incarceration higher in the North to begin with, but it rose sharply in the North after 1880, even while dropping sharply in the South after 1900. What exacerbated the racial disparity in the North was the fact that blacks were competing with lower-class immigrants from Europe, many of whom—particularly the Irish—had come to dominate law enforcement and were looking for any excuse to arrest blacks. In a sense, the Irish—who, ironically, had gotten a reputation as troublemakers when they first immigrated—traded places with blacks. “As the incarceration rate of Irish immigrants and their children in Great Migration states declined from 245 to 158 people per 100,000 between 1880 and 1950, the nonwhite incarceration rate leapt from 203 to 594.”

Muller, C., “Northward Migration and the Rise of Racial Disparity in American Incarceration, 1880–1950,” American Journal of Sociology (September 2012).

This is more evidence that the North has had a long history of issues over race after the Civil War. The typical narrative often doesn’t allow for this; the story often goes that the South was the racist and discriminatory part of the country and the Jim Crow laws prove this. But the North may not have been much better. In addition to these differences in incarceration rates, there is evidence of:

1. Increasing levels of residential segregation between whites and blacks emerging in many Northern cities in the early 1900s. As the Great Migration picked up, blacks were pushed to live in black areas, not in white neighborhoods. For example, the thousands upon thousands of blacks who entered the city were forced into the Black Belt. See the book American Apartheid, among other research.

2. Many smaller Northern communities had “sundown laws” that did not allow blacks to stay in the community after dark. While blacks had unprecedented residential mobility in the two decades after the Civil War, these new sundown rules pushed blacks back into major cities. See the book Sundown Towns.

New developments tower over Mecca

Several new developments in Mecca threaten to dwarf the holy sites:

Shooting 26 searchlights 10km into the skies, and blaring its call to prayer 7km across the valley, the Abraj al-Bait is also the world’s second tallest building. Encrusted with mosaics and inlaid with gold, it is the most visible (and audible) sign of the frenzied building boom that has taken hold of Saudi Arabia’s holy city over the last 10 years. “It is truly indescribable,” says Sami Angawi, architect and founder of the Jeddah-based Hajj Research Centre, who has spent the last three decades researching and documenting the historic buildings of Mecca and Medina, few of which now remain. In particular, the house of the prophet’s wife, Khadijah, was razed to make way for public lavatories; the house of his companion, Abu Bakr, is now the site of a Hilton hotel; and his grandson’s house was flattened by the King’s palace. “They are turning the holy sanctuary into a machine, a city which has no identity, no heritage, no culture and no natural environment. They’ve even taken away the mountains,” says Angawi…

Along the western flank of the city are the first towers of the Jabal Omar development, a sprawling complex that will eventually accommodate 100,000 people in 26 luxury hotels – sitting on another gargantuan plinth of 4,000 shops and 500 restaurants, along with its own six-storey prayer hall. The line of blocks, which will climb to heights of up to 200 metres and terminate in a monumental gateway building, share the clocktower’s Islamic-lite language: a cliched dressing of pointed arches and filigree grillwork plastered over generic concrete shells…

Another development of repetitive slabs, echoing Jabal Omar’s toast-rack urbanism, is slated for the northern side of the Grand Mosque, at al-Shamiya, while a $10bn plan to provide an extra 400,000 sq metres of prayer halls there is almost complete. Standing like a gigantic triangular slice of wedding cake, this building will accommodate 1.2m more worshippers each year, but it has come at a price…

The Kaaba is the holy black cube in the centre of the Grand Mosque, around which pilgrims walk; proximity to it has become the ultimate currency, allowing hotel suites with the best views to charge $7,000 per night during peak seasons. This unique concentricity, with everything determined by its orientation towards the hallowed centre, has spawned a strangely diagrammatic radial urbanism. From above, like a sea of iron filings pulled by a magnet, the whole city appears to crowd round a core, the vortex of pilgrims giving way to an equally swirling current of tower blocks. It is the axis of prayer writ large in concrete.

The contrast seems stark: a holy site versus ultra-modern development. Is this growth machine development, meaning development primarily about generating profits from pilgrims, run amok? That this is emerging in Saudi Arabia shouldn’t be too surprising. Oil money has to be spent somewhere. Plus, cities like Dubai and Abu Dhabi have been getting a lot of attention in recent years for their massive developments and I imagine Saudi Arabia would like to match some of that. Yet, Dubai and Abu Dhabi aren’t also known for being major religious sites.

Also, whenever I see stories like this, I am reminded of the amazing pace of development in some cities (particularly in China and oil-rich Middle East nations) around the world: from populated, primarily low-rise cities to massive, tall, expensive developments.

Would you rather have $10 land in rural Canada or houses for under $100 in Detroit?

I saw a story about a small rural town in Canada trying to lure in new residents by offering land for $10:

In an effort to jump on the oil boom in that part of the country, officials are once again selling undeveloped land for a mere $10, an initiative they first started in 2010. Back then they had 14 lots for sale, 11 of which have houses built on them today, economic development officer Tanis Chalmers told ABC News .

That plan was so successful that in September the Rural Municipality of Pipestone, of which Reston is the biggest town (population: 550), decided to put up an additional 10 lots for sale, along with the three left from 2010. Nine remain, “But I’ve had offers on them already from both Canada and the U.S,” said Chalmers, adding that the initiative has been so effective that the local school finally “has a standalone kindergarten class.”…

The plan is pretty straightforward: To purchase a property, wannabe homeowners have to sign an agreement and put down a $1,000 deposit. Once a lot is purchased, owners have 90 days to begin construction, and 12 months to complete it. As soon as the town receives your occupancy permit, they will refund $990 of the original down payment…

As further incentive, the town is offering a $6,000 grant to people who’ve built a new house or purchased an existing home in the rural municipality. The grant, mind you, can be used for anything from home upgrades to a new car. Chalmers says taxes hover around $1,500 to $2,500 per year.

This reminded me of stories in recent years about cheap houses in Detroit. Here is one example:

“I was living in Chicago and a friend told me that houses in Detroit could be had for $500,” said Brumit, a financially strapped artist who thought he had little prospect of owning his own property. “I said if you hear of anything just a little cheaper let me know. Within a week he emails me a photo of a house for $100. I thought that’s just crazy. Why not? It’s a way to cut our expenses way down and kind of open up a lot of time for creative projects because we’re not working to pay the rent.”…A third of the population are unemployed. Property prices have fallen 80% or more in large parts of Detroit over the last three years. The average price of a home sold in the city last year has been put at $7,500 (£4,900)…

Banks are selling off properties in the worst neighbourhoods, which are usually surrounded by empty and wrecked housing, for a few dollars each. But even better houses can be had at a fraction of their former value.

Technically, Brumit paid $95 for the land and $5 for the house on Lawley Street – which fitted what estate agents euphemistically call an opportunity.

I suspect more people would jump at the rural opportunity. While there might be more amenities nearby in Detroit (you mean those winning Tigers can’t boost home prices like winning NFLteams  supposedly can?), the idea of living in Detroit itself would scare a lot of people. What might happen in the neighborhood? Can the city provide basic services? On the other hand, the rural property might be a long way from anything worthwhile but it could offer some access to nature, there probably aren’t as many worries about neighbors, and there is some appeal to starting from scratch. If we wanted to stretch this explanation out even further, this could be a sign of the urban/rural divide in the United States; economically similar opportunities in the big city and the country don’t attract the same level of cultural and residential interest.

Twin Cities’ Metropolitan Council tries to project 30 years into the urban future

The Metropolitan Council for the Twin Cities region in Minnesota is working on a new plan that tries to project urban changes in the next 30 years:

For example, he noted, the Twin Cities region will have 900,000 more people, with twice as many elderly. Also, by 2040, 43 percent of the region’s population will be people of color, up from today’s 24 percent.

Big changes are already being seen in housing patterns. The share of building permits issued in developing suburbs has been declining since 2008, when they had 66 percent of the total. But by 2011, less than half were issued in the second- and third-ring suburbs for the first time in a decade…

“But what we’ve seen in the few years is that employment did not increase between 2000 and 2010. Employment dropped in the seven-county area, so growth management isn’t the issue it was before,” she said.

Instead, the new plan will likely focus more on “what the transit system means for our region, thinking out how new light-rail lines will influence new development and thinking about water supplies.”

A quick summary of these predicted changes: a more diverse population, slower or less growth on the suburban fringe, a struggle to create good-paying jobs, preserving local natural resources, and looking to build more effective mass transit that might also boost local development efforts. I suspect a lot of regions, particularly ones without high levels of growth, will have similar concerns. As cities and communities age, infrastructure will cost more, regions will continue to compete with each other for high-tech and white-collar jobs, and new populations might challenge the existing character of places and regions.

A note: if you have read the work of Myron Orfield (for example, see American Metropolitics), you will have heard of the Metropolitan Council. Compared to other metropolitan regions, the Twin Cities has a metropolitan agency with some teeth:

The Metropolitan Council or Met Council is the regional governmental agency and metropolitan planning organization in Minnesota serving the Twin Cities seven-county metropolitan area. The Met Council is granted regional authority powers in state statutes by the Minnesota Legislature. These powers can supersede decisions and actions of local governments. The legislature entrusts the Council to maintain public services and oversee growth of the state’s largest metro area. This agency is similar to Metro in Portland, Oregon in that both agencies administer an urban growth boundary…

In 1967 the Minnesota Legislature created the Metropolitan Council in response to growing issues of septic tank wastewater contamination. During that time, it was recognized there were systematic problems which transcended coordination of any one agency. There were more than 200 municipal agencies in existence then.

Additional acts of the legislature passed in 1974, 1976, and 1994 expanded the role and powers of the Met Council, merging it with transit and waste control commissions to become a unified regional authority.

In other words, the planning being done could have a big impact on the next few decades in the region.

Why New Yorkers and pigeons get along

A sociologist explains the social interaction New Yorkers have with pigeons:

For more than three years, Jerolmack observed the ways in which people interact with pigeons in cities. His forthcoming book, The Global Pigeon, which, as he put it, seeks to examine “our social experience of animals,” draws from that research. Yesterday evening he spoke about our own city’s rather vexed relationship to the birds.

In the 1960s, for instance, Thomas P.F. Hoving, the former city parks commissioner and longtime director of the Metropolitan Museum of Art (not to mention the subject of a famed John McPhee New Yorker profile from 1967), called pigeons “rats with wings,” an epithet—often wrongly attributed to Woody Allen—that really stuck. Hoving cited the species, along with litterers and vandals, as a plague on Bryant Park. The park’s supervisor at the time, Andrew Petrochko, told the New York Times that “the homosexuals … make faces at people [and] once the winos are dried out at Bellevue, they make a beeline for Bryant Park.”…

Despite their bad reputation, though, Jerolmack noted that our urban encounters with pigeons “are profoundly social.”

“The impulse to feed pigeons is not so different from wanting to chat with strangers,” Jerolmack said, speaking about one of the subjects for his book, Anna, the elderly pigeon lady who regularly feeds the birds at Father Demo Square, the tiny enclave in the West Village where Jerolmack’s research began.

This sounds like it could be a testable hypothesis: do city dwellers have more positive, social relationships with wildlife (not including pets or animals connected to a household) than people who live in suburbs or rural areas? Cities aren’t typically known for their wildlife but perhaps this could be tied to Simmel’s arguments in his piece “The Metropolis and Mental Life.” He suggested there were too many people for individuals to interact with in big cities so they would have to develop blase attitudes to protect themselves. But what if they could interact safely with pigeons (and even ducks and squirrels)? Or perhaps this is tied to romanticized (or real?) notions residents have about needing to connect with nature in the middle of the “concrete jungle.”
