Plans for real megalopolis in China

Posted on by

The idea of a megalopolis dates back to the middle 1900s when people started thinking that collections of large cities, such as the large American cities on the Eastern seaboard including Boston, Hartford, New York City, Philadelphia, Baltimore, and Washington D.C., such be considered as a larger grouping. But even this good example has cities separated by decent distances.

China is planning its own version of a megapolis near Hong Kong. The plans including merging nine cities with a combined population of 42 million:

The “Turn The Pearl River Delta Into One” scheme will create a 16,000 sq mile urban area that is 26 times larger geographically than Greater London, or twice the size of Wales.

The new mega-city will cover a large part of China’s manufacturing heartland, stretching from Guangzhou to Shenzhen and including Foshan, Dongguan, Zhongshan, Zhuhai, Jiangmen, Huizhou and Zhaoqing. Together, they account for nearly a tenth of the Chinese economy.

Over the next six years, around 150 major infrastructure projects will mesh the transport, energy, water and telecommunications networks of the nine cities together, at a cost of some 2 trillion yuan (£190 billion). An express rail line will also connect the hub with nearby Hong Kong.

“The idea is that when the cities are integrated, the residents can travel around freely and use the health care and other facilities in the different areas,” said Ma Xiangming, the chief planner at the Guangdong Rural and Urban Planning Institute and a senior consultant on the project.

This sounds like a sizable project. The article suggests that this is being done for several reasons: to achieve economy of scale in certain things (like medical services) and the ability to create unified policies for the region (including transportation and pollution initiatives). And this grouping of cities could conceivably grow even larger if Hong Kong was ever added to this mix.

The article calls this a “mega city” but I think it would fit the definition of a megalopolis perfectly. In fact, compared to most examples of a megalopolis, this one would be much better suited to the idea: the cities are relatively close and will be highly connected. Additionally, the cities are laid out more in a circle pattern rather than a line, allowing a variety of connections between urban centers.

I wonder how many planners around the world would approve of such a project. Combining certain infrastructure has its appeal as planning can be done on a broader scale and without cities constructing competing systems.

Interestingly, there are no plans to give the region a new name: “It will not be like Greater London or Greater Tokyo because there is no one city at the heart of this megalopolis.” Will future residents identify themselves as residents of the region or their specific city?

Portland faces mocking on television show

Posted on by

Some large cities have better images than others. Portland generally has a positive reputation, particularly among urban sociologists and planners who have admired the city’s restrictions on urban sprawl.

So what happens when Portland takes some mocking from a new television show named “Portlandia”?

For years, many residents here have reacted with practiced apathy and amusement toward the national fascination with Portland. Outsiders and media critics have glowed over everything from its restaurants to its ambitious transit system of streetcars and light rail. Yet with “Portlandia,” the flattery has given way to mockery, however gently executed, of this liberal city’s deliberate differentness…

In a popular line from the show, which is on IFC, Mr. Armisen’s character describes Portland as a place “where young people go to retire.” Sure enough, economists have shown that the city in recent years has drawn a disproportionate amount of young people, and that many of them end up being underemployed…

The show has limits as social science. While many parts of Portland feel like one big group hug, the city is a complicated place, struggling with government budget cuts, manufacturing losses and the housing downturn even as demand for office space downtown has risen. The Gilt Club restaurant is just a few blocks from a Salvation Army shelter.

If Portland residents do not like the portrayal of their city, they shouldn’t worry too much: the Independent Film Channel, home to “Portlandia,” is not a very well-known channel.

Of course, how residents see one’s city can differ quite a bit from the view of outsiders. And television is not necessarily a good reflection of reality. It will be interesting to watch how Portland residents continue to respond to this show, particularly if the humor has an edge to it or takes on sacred cows.

Seeing China’s growth in two pictures of Shanghai

Posted on by

Urban growth and building can occur at a very quick pace. The population growth and building in Chicago in the late 1800s was tremendous. BusinessInsider has two pictures that show the rapid construction that took place in one part of Shanghai between 1990 and 2010.

The pictures are fascinating in themselves. But an explanation of exactly what happened and how it happened would be even better.

Which comes first, the jobs or the people?

Posted on by

New research from an urban sociologist suggests that the conventional wisdom that jobs bring new residents doesn’t match reality:

But according to a study in the Journal of Urban Affairs, MSU’s Zachary Neal found the opposite to be true. Bringing the people in first – specifically, airline passengers traveling on business – leads to a fairly significant increase in jobs, he said.

“The findings indicate that people come first, then the jobs,” said Neal, assistant professor of sociology. “It’s just the opposite of an ‘If you build it, they will come’ sort of an approach.”

For the study, Neal examined the number of business air-travel passengers in major U.S. cities during a 15-year period (1993-2008). Business passengers destined for a city and not just passing through are a key to job growth, he said.

Attracting business travelers to the host city for meetings and other business activities by offering an easily accessible airport and other amenities such as hotels and conference centers is one of the best ways to create new jobs, Neal said. These business travelers bring with them new ideas and potential investment, which creates a positive climate for innovation and job growth. In the study, Neal analyzed all permanent nonfarm jobs…

Neal added that business airline traffic is far more important for a city’s economic vitality than population size – a finding he established in an earlier study and reaffirmed with the current research.

So will cities alter their strategies for creating jobs to match this research?

This could be taken as a call for improved infrastructure, specifically airports and convention centers. Such projects can be expensive and difficult to get off the ground. (As a good example, see the case of the proposed expansion of O’Hare Airport.) But if Neal is right, then having more capacity to bring in business travelers would lead to more jobs. The upfront cost to expand the airport or convention center or attract hotels for business travelers would pay off down the road.

Reaction to Newsweek’s list of “dying cities”

Posted on by

Search for “dying city” and “Newsweek” and what you will see in the Google results is not the original article but rather reactions from some of the listed cities. Newspapers in South Bend, Rochester (NY), and Grand Rapids have voiced their displeasure.

This recent list from Newsweek is based on Census data and the cities that experienced the greatest population declines from 2000 to 2009:

We used the most recent data from the Census Bureau on every metropolitan area with a population exceeding 100,000 to find the 30 cities that suffered the steepest population decline between 2000 and 2009. Then, in an attempt to look ahead toward the future of these regions, we analyzed demographic changes to find which ones experienced the biggest drop in the number of residents under 18. In this way, we can see which cities may have an even greater population decline ahead due to a shrinking population of young people.

Here are the 10 cities that had the steepest drop in overall population as well as the largest decline in the number of residents under the age of 18.

Some thoughts about this data:

1. All of these cities, except two (one in FL, one in CA), are in the Rust Belt. Many of these cities are not surprises.

2. The local reactions seem to be expressions of civic pride. People in these cities can’t ignore the population loss but they are right in saying their cities are not going completely to waste. There are some good things going on in these places but broader population trends are working against them.

3. “Dying city” does not equal “dead city.” Dying doesn’t mean that everybody is leaving, just that these cities lead the country in percentage population loss. A real “dead city” would have no population left. These cities are from that point.

4. Perhaps what angers locals most is that articles like these can further negative stereotypes. These places already suffer from perception problems and lists like this do not help. For example, it is any surprise that Detroit continues to lose population after years of commentators saying how bad of shape Detroit is in? People probably leave places like Detroit for reasons more important than punditry (reasons like jobs, opportunities, etc.) but it could play some role.

Considering what the “green Loop” might look like

Posted on by

Amidst talk of eco-cities, a Chicago architectural firm has put together a plan to reduce carbon emissions by 80 percent within Chicago’s Loop. How to accomplish this: retrofit older buildings rather than building a lot of new, green buildings.

The architects break what they call the Central Loop into four types of buildings: heritage buildings (1880-1945), which are clad in heat-absorbing masonry and have operable windows; midcentury modern buildings (1945-75), which hog energy due to their vast expanses of glass and heavy reliance on air conditioning; post-energy-crisis buildings (1975-2000), which show greater energy-efficiency but are burdened by an unanticipated rise in computer use; and energy-conscious buildings (2000-present), which continue to improve efficiency but are in relatively short supply.

That brings us to the heart of the matter: The key to cutting pollution isn’t building new green buildings. There simply aren’t enough of them to make a difference. The only way to lower our carbon footprint is to make the buildings we already have more energy-efficient.

That’s possible, as evidenced by the recent transformation of the Merchandise Mart, the massive yet graceful Art Deco commercial and trade show building along the Chicago River. At 4.2 million gross square feet, it’s one of the world’s largest buildings. By taking a variety of steps — from installing energy-saving water pumps to promoting eco-friendly products to the building’s tenants — the Mart cut its overall energy consumption by 21 percent from 2006 to 2010, executives there say.

I wonder how this plan would be received by businesses and building owners. While they suggest energy costs will decrease in the long run and rents may increase, such retrofitting could be costly in the short-term and there could be some anxiety about doing these things in the middle of a tough real estate and business market.

And how much would the City of Chicago really get behind this? Mayor Daley has drawn plaudits in the past for promoting ideas like rooftop gardens but these are limited in number. The City itself faces significant financial troubles in the coming years and I imagine issues like jobs, pensions, crime and the number of police in the streets, will dominate conversations for a while.

I would enjoy seeing their charts or models to see which particular buildings in the Loop use more or less energy. The picture that leads this report on the plan probably shows carbon emissions or energy use by building.

Images of a planned Chinese eco-city

Posted on by

While there is lots of talk about greening cities and how cities themselves are more green than patterns of sprawl, these images from the planned Chinese city of Tianjin show what a true eco-city might look like.

On the whole, the city looks green, clean, and futuristic. Would a city built in this manner look as good as these pictures? And is this something that could easily be replicated elsewhere or will it need to be heavily subsidized and monitored?

An intriguing question: just how many parking spots are in the United States?

Posted on by

The Infrastructurist reports on a new academic study that considers the full environmental impact of parking. But in order to provide an answer to this query, the researchers had to first consider another question: just how many parking spots are there in the United States?

Turns out that’s no easy task; in fact, according to the authors, no such “nationwide inventory” has ever been done. “It’s kind of like dark matter in the universe,” Donald Shoup, the so-called “prophet of parking” (and not part of the study), told Inside Science. “We know it’s there, but we don’t have any idea how much there is.” When the Berkeley researchers crunched the numbers, they came up with five scenarios of available U.S. parking that ranged from 105 million spots to 2 billion. Give or take, I guess.

The most likely estimate points to roughly 800 million spaces across the country, and the construction and maintenance of those spaces do, in fact, take a large cumulative toll on the environment. When parking spots are taken into account, an average car’s per-mile carbon emissions go up as much as 10 percent, the authors conclude. They also report that, over the course of a car’s lifetime, emissions of sulfur dioxide and soot rise 24 percent and 89 percent, respectively, once parking is properly considered.

Those are just part of a broad “suite of impacts” that includes previously studied costs like the “heat island effect” — the term for when dark pavement raises the temperature of a city, leading to additional energy demands for cooling. And atmospheric costs are only part of the suite. According to the paper’s lead author, Mikhail Chester, there may be a larger infrastructure for parking than for roadways. If that’s the case, there would seem to be another great cost to all this parking: the relative cost of useful space.

I like the comments from “the prophet of parking.” While there are not probably too many people in the world who would want to know the exact figure of parking spots in the United States, it is important to know this fact in order to understand the larger impact of parking.

Parking itself is an interesting phenomenon. In a culture that loves automobiles, parking spots are essential features are many places. There is much evidence that if Americans can’t find a relatively cheap parking spot, they are likely to go elsewhere. Some of the allure of the shopping mall, with the first ones constructed in the mid 1900s, was that the consumer had a vast area of free parking as opposed to the crowded streets of downtowns. Homes have to have their own form of parking spaces, to the point of many homes from recent decades leading with their garages (and earning the nickname “snout houses” for how this garage protrudes toward the street).

But of course, as this study points out, parking spots come at a cost.

A related question that I would be interested in knowing the answer to: how many parking spots are occupied at different times of the day? How many parking spots in America are constructed for the 8-5 work hours and then sit empty the rest of the day?

Cities that are losing population

Posted on by

The list of the top seven American cities in population loss (measured as a percentage of total population) is not surprising: New Orleans, Flint, Cleveland, Buffalo, Dayton, Pittsburgh, and Rochester (NY). And outside of New Orleans, why these cities have lost population is also not difficult to figure out: a loss of manufacturing jobs.

But a list like this raises some questions about cities:

1. Is it that unusual for cities to lose population? If cities can boom, as these cities did during the industrial boom, why can’t they also go bust?

2. The headline on the article is misleading: “US cities running out of people.” There are still plenty of people in these communities – what is unusual is that the population is declining.

3. Is there a point where these population losses will stabilize? I always wonder this about cities – some people stay because there are still some jobs, particularly medical, municipal, and service jobs available.

4. Is there something the federal government could do to help these communities reverse these trends? Is there a public interest in not letting cities like these slowly die?

5. Measuring the city’s population is perhaps not the best way to go about it. How have the metropolitan populations changed? Are there still people in the region? This would make a difference.

Millennium Park: an example of how growth machines work

Posted on by

Within a story about whether Chicago will be able to move forward with large development projects in the next few years, a historian describes how Millennium Park, a significant undertaking, came about:

Indeed, as Chicago ponders its future, it may be useful to view Millennium Park not as a triumph to be repeated, but as a shining exception, one that occurred only because the stars aligned and Daley had created order in Chicago’s turbulent political universe.

After years of fruitless talk, the story goes, the park got its start in 1997, when the mayor peered down from his dentist’s office along Michigan Avenue and decided to turn that dusty railroad yard in Grant Park’s northwest corner into an urban showcase.

By then, Daley had been mayor for eight years and had consolidated his grip on power. Key figures in the park’s creation, including major donors like the Pritzker and Crown families, were “in many ways indebted to, dependent upon and allied with the mayor,” Gilfoyle said. They wanted to please Daley, he explained, partly because their real estate and other holdings might benefit from future city action.

All roads, in other words, led to Daley. And the economic winds were at his back. The late 1990s dot-com boom gave the park’s chief fundraiser, former Sara Lee Corp. CEO John Bryan, enormous wealth to tap. Without it, Gilfoyle said, the 6-year-old park might never have happened.

Today, with such favorable conditions a distant memory, Chicago’s builders are scrambling to find new paths to get things done. One is to push projects ahead step by step rather than in a single, expensive rush, as at Millennium Park.

This sounds like a classic description of growth machine development: the mayor wants something to get done, major donors and partners are sought and found, and a large and impressive park is able to be built on a spot that had been an industrial location/blighted site for years.

This is an interesting example considering the context of the rest of the story: Chicago will have a new mayor (with less consolidated power) and also is facing significant budget issues. Growth machine politics may not be possible at least with the new mayor for a while though other power brokers could emerge. Growth machines are also more limited when money from businesses and local governments is scarce.

Another question one could ask after reading this story: how unusual was it for both Mayor Daleys to undertake so many significant projects? Around Chicago, they are known for having significant building legacies. Are there mayors in other major cities with similar records or are they truly unusual?
