A new analysis authored by Todd Litman at the Victoria Transport Policy Institute concludes that sprawl costs the U.S. economy more than $1 trillion every year. [...]
The optimal density Litman uses in the report is only about 23 people per hectare. Add those 2.2 billion people to global cities at a density of about Atlanta, and we'd need the equivalent of all the land in India to accommodate them. — washingtonpost.com
How much more does it cost the public to build infrastructure and provide services for sprawling development compared to more compact neighborhoods? A lot more, according to this handy summary from the Canadian environmental think tank Sustainable Prosperity.
To create this graphic, the organization synthesized a study by the Halifax Regional Municipality [PDF] in Nova Scotia, and the research is worth a closer look. — streetsblog.org
A new study by Thomas Laidley, a sociology doctoral student at NYU [...], uses satellite images to develop a new and improved “Sprawl Index,” which he links to a wide range of outcome measures.
Perhaps the biggest surprise is that L.A. ranks as the least sprawling metro in the country, ahead of New York and San Francisco. — citylab.com
one-story peanut butter, noun: in reference to urban sprawl, how it spreads and oozes.The term comes courtesy of Archinector and Archinect Sessions co-host, Donna Sink, who recalls W. Kirby Lockard (1930-2007), Professor of Architecture at University of Arizona, using it to describe sprawl...
Urban densities are not trivial, they severely limit the transport mode choice and change only very slowly. Because of the large differences in densities between Atlanta and Barcelona about the same length of metro line is accessible to 60% of the population in Barcelona but only 4% in Atlanta. The low density of Atlanta render this city improper for rail transit. — usa.streetsblog.org
In the wake of economic reforms in the 1990s that helped set off the largest urban migration in history, China had the rare opportunity to embrace cutting-edge city-building approaches as it expanded its skyline. It could have avoided the mistakes that made Los Angeles into the land of gridlock, or bypassed the errors that turned the banlieues of Paris into what one American planner calls “festering urban sores”.
But China looked back instead of forward. — theguardian.com
Marshall, Garrick and Piatkowski are talking about a different set of health concerns: not communicable diseases like cholera, but lifestyle diseases like diabetes. "The literature suggests," they write, "that the shift in industrialized nations toward a more sedentary lifestyle is linked to increasingly auto-dependent lifestyles, which in turn is linked to lower density developments and auto-friendly land uses." Maybe we're designing places, in other words, that make it harder to be active. — washingtonpost.com
A new report from Reid Ewing and Shima Hamidi of the University of Utah, lead researchers on the aforementioned rankings, gets at that question. Ewing and Hamidi scored the largest 162 U.S. urbanized areas on the Sprawl Index — or, if you're feeling optimistic, the Compactness Index — for 2010. (Urbanized areas reflect development better than fixed metro area boundaries do.) Then they applied the index to the same cities in 2000 to show the change over time. — citylab.com
In a series of photos taken over seven years, now published in a new book called Ciphers, photographer Christoph Gielen shows a different perspective on sprawl, intended to get more people to question typical patterns of development.
"I meant for Ciphers to be provocative at a time when we are witnessing a phenomenal escalation in urban construction ... when entire cities are emerging fully formed in India and China, rather than slowly evolving," says Gielen. — fastcoexist.com
It may not seem like it when you’re stuck in traffic on the 110 Freeway, but Southern California is home to some of the least-sprawling metro areas in the country.
That’s according to a study out today from Smart Growth America, which attempted to measure the concept of urban sprawl in 221 metro areas nationwide. The study ranked the Los Angeles, Orange County and Santa Barbara regions in the 25 least-sprawling. — latimes.com
“Ultimately people can’t get around conveniently because they are far away from everything.” And it is this observation that for me epitomizes the problem of the driverless car — it’s the worst kind of solutionism. By becoming so enamored with how technology might transform the car, we’ve neglected to adequately explore how getting rid of cars might transform how and where we live. We’d do well to heed Gorz’s exhortation to “never make transportation an issue by itself.” — opinionator.blogs.nytimes.com
It's a given that America continues to be a car-obsessed society despite the more painstaking reality of driving a car in many major cities of today. In The New York Times, editor Allison Arieff of SPUR points out that the U.S. is still fixated on selling, using and enhancing the car when...
This 1959 film, "Community Growth, Crisis and Challenge," warns citizens, developers, and city officials of the dangers of urban sprawl. This historical artifact, co-sponsored by the National Association of Home Builders (NAHB) and the Urban Land Institute ULI) provides alternative approaches to land development. The film was produced by the NAHB. — ULI
The Urban Land Institute is clebrating their 75th birthday this year. To join in the celebration, enjoy this classic film warning of the perils of urban sprawl sponsered by them and the National Association of Home Builders. You can see their other videos on YouTube by going...
