Do Sustainable Cities Have a Future?

This article is reprinted from the American Prospect.

A "green revolution" is burgeoning in America's cities and towns.

And it's a surprise. Six years ago, as we exited an economically exuberant but perilously polluting 20th century, the idea would have seemed chimerical. True, by the 1990s we'd begun to talk about community and global sustainability; President Clinton even appointed a White House council on the topic. But the conversation proved to be a tad ahead of its time. It exhibited little of the intensity with which the green ideal is today being talked up, and in some places, truly implemented.

A set of mix-and-match developments explain the change. Foremost and scariest among them is the mounting scientific evidence of fast-advancing, potentially cataclysmic global climate change. Then there is the growing realization of oil's short-term future in the dangerous world that September 11 dramatized.

Among the results are heightened interest in hybrid cars and renewed focus on wind farms, solar energy, biofuels, and other renewables; a burgeoning "smart-growth" movement in our states and regions; worry on the health front about sedentary lifestyles, obesity, loss of natural connections; green roofs and strong revival of urban parks; and breakthroughs to pinpoint waste and pollution in our great infrastructure systems, enabled by more sophisticated geographic information system (GIS) technology.

If the new, green, urban alchemy has an epicenter, it's Chicago. Once the embodiment of smoky factories and belching locomotives, the erstwhile City of the Big Shoulders has led the new green wave with beds of flowers and blossoming pots hung from new downtown street lamps.

A big share of the Chicago credit goes to Mayor Richard J. Daley and his allies. There's a green roof on City Hall and greenery along roadway medians stretching out into the neighborhoods. Asphalt schoolyards have been converted to grass, vacant lots turned into community gardens, greenways and wildlife habitat nurtured. Major reinvestment is occurring in the city's 570 parks, 31 beaches, and 16 historic lagoons. And there's a dramatic "big splash" -- 3-year-old Millennium Park, $475 million worth of lush greenery, sculpture, fountains, and more on the lakefront that's drawing 4 million visitors a year, many to its stunning outdoor music theater.

Says Chicago Alderman Mary Ann Smith: "We're creating places people want to be, not places people want to flee." In fact, Chicago has registered America's most dramatic "back-to-the-city" movement, with tens of thousands of new downtown residents.

Cities Taking the Lead

But Chicago is no exception. From Philadelphia to Seattle, Boston to San Diego, city officials agree that green urban settings are a critical draw in an era when highly educated, mobile professional workers -- the economic gold of the times -- gravitate to attractive, welcoming, and healthy places.

What's more, claim the apostles of green, property tax yields from homes and apartments near parks are significantly higher. Tree-lined streets alone increase property values some 15 percent.

Quite quickly in this decade, the familiar definition of "green" has advanced from trees and plants and parks to a much more inclusive vision of city and metropolitan planning. Moreover, it now comprises an array of environmental issues, including energy saving and renewable sources, reduced burning of fossil fuels, cleaner air and water, improved wastewater removal systems, and redevelopment of "brownfields" sites.

Energy standards for buildings -- the familiar LEED standards of the U.S. Green Building Council -- are a case in point. They're quickly advancing from handfuls of pioneering buildings to a preferred benchmark in new construction. Despite the 2 percent to 4 percent price premium for fully energy-efficient buildings, a growing number of businesses are opting for a LEED standard. Part of the justification is long-term energy savings; another rationale, increasingly cited, is the dramatically increased productivity reported among employees in quality green structures.
