New Track Homes?

Dongtan, located on an island off of Shanghai, China, is one of the world's
first truly green cities. It's still in early development but the bridge and
tunnel link to the mainland is now being built. This planned, zero-waste, energy-efficient community is to reach 500,000 residents by 2050, all the while maintaining much of the natural wetlands that provide one of the few remaining refuges for birds in a constantly developing country. The city will be powered mainly by sea breezes and only clean-running vehicles will be permitted.
It is so good to see a new brand of planned community.
