Job Sprawl? Horrors!
posted in News commentary |The Brookings Institute just discovered the jobs are moving to the suburbs along with people. According to their press release, this decades-old trend “undermines long-term regional [and] national prosperity.”
“Allowing jobs to shift away from city centers hurts economic productivity, creates unsustainable and energy inefficient development, and limits access to underemployed workers,” says Brookings senior fellow Robert Puentes. But neither he nor the author of the study, Elizabeth Kneebone, actually proves that any of these things will happen — or how we’ve managed to survive for so long in the face of this adversity.
The study itself uses the curious procedure of measuring changes in job numbers within three miles, three to ten miles, and outside of ten miles of downtown. That would be fine if all metro areas covered the same geographic area, but the urban areas reviewed by Brookings ranged from Atlanta, which covers 2,000 square miles, to Trenton, which covered less than 100 square miles in 2000.
Not surprisingly, Trenton was found to have a lot less job sprawl than Atlanta. “The larger the metro area,” the study insightfully observed, “the more likely people are to work more than 10 miles away from downtown.” Well, duh.
Brookings’ rather strange criteria meant that metro areas that are beloved of the anti-sprawl crowd, such as Portland and San Jose, were found to have some of the worst job sprawl. This shouldn’t be at all surprising: a key plank in the smart-growth platform is to promote a jobs-housing balance. Achieving this goal requires that lots of jobs move to the suburbs to balance the concentration of jobs downtown.
I guess Brookings — or at least Puentes and Kneebone — decided to come out against smart growth.
Just why is it so important that jobs be concentrated downtown? Kneebone uses the old argument that more dispersed jobs require more driving, but never mentions that it allows people to drive in less congestion. Kneebone also frets that job dispersal takes potential jobs away from inner-city low-income workers. But this contradicts the whole point of the smart-growth jobs-housing balance thing.
Finally, Kneebone claims that infrastructure for low-density development costs more than for high densities. But this is different than saying that infrastructure 10 miles away from downtown costs more than infrastructure downtown. In fact, it probably costs a lot less. Even if infrastructure in the suburbs costs more, those costs are more than offset by other savings.
For example, planners in Calgary, which the Antiplanner recently visited, just published a report on the costs of sprawl. The report finds that Calgary’s sprawl alternative (also known as the current direction) will cost the city $11.2 billion more to serve a projected 1.3 million new residents than its preferred, compact alternative.
Calgary has about 2.6 people per dwelling unit, so $11.2 billion averages out to $22,000 per home. Against that extra cost, the average cost of a home in the Vancouver metro area was (according to the 2006 census) almost $140,000 more than in the Calgary metro area. Since Vancouver has long had a smart-growth plan like the one Calgary wants to adopt, this is a rough approximation of the trade off.
In other words, it’s not all about infrastructure costs. Both businesses and homebuyers must consider land costs, taxes, and the costs of regulation, all of which tend to be lower the further you get away from downtown.
Moreover, nearly all of Calgary’s added costs of sprawl are roads, water, and sewers. These can easily be charged to the people using those facilities. So what’s wrong with charging people and letting them decide if they want to live or work downtown or on the urban fringe?
In other words, Kneebone is making a mountain out of a well-explored molehill. Alan Pisarski documented the dispersal of jobs decades ago in his Commuting in America series. Brookings managed to get some nice coverage for this report, but all it really means is that decentralization is going to continue no matter what the planners want.
Update: This article from the Buffalo News affirms why jobs are moving away from downtowns: “because the outer suburbs have the one thing many businesses think essential for their designs — large amounts of land that would accommodate the modern vision of a workplace.” Keeping these jobs in the city requires that cities engage in expensive brownfield clean ups — just one more cost ignored by Brookings’ intrepid researchers.
