China's Dongtan To Take An Ecosystem Approach to Urban Planning
"Dongtan breaks ground later this year on a plot about the size of Manhattan on Chongming Island. The first condos and commercial space will hit the market by 2010, around the time a 12-mile bridge and tunnel combo and subway extension will link the city to Shanghai's new international airport (45 minutes away) and financial district (30 minutes). By 2050, Dongtan will have a half-million residents, more than Miami or Atlanta today.
That may count as a cozy little town in a country of 1.3 billion people. But Dongtan is a dramatic gambit, and not just because a whole city will rise, fully realized, from nothing. With Dongtan, Arup is testing a radical new approach to urban design, one that suggests cities across China and the rest of the developing world can actually get greener as they grow.
Dongtan's master plan - hundreds of pages of maps, schematics, and data - has almost nothing to say about architectural style. Instead, it outlines the world's first green city, every block engineered in response to China's environmental crisis. It's like the source code for an urban operating system. "We're not focused on the form," Gutierrez explains. "We're focused on the performance of the form." He and his team imagine a city powered by local, renewable energy, with superefficient buildings clustered in dense, walkable neighborhoods; a recycling scheme that repurposes 90 percent of all waste; a network of high tech organic farms; and a ban on any vehicle that emits CO2."
