Describing a plan for Melbourne, Australia, Alex Steffen explains how urban density improves quality of life for everyone:
The city’s growing quickly, needs to add a million people over the next decade or two, but they don’t want that to be sprawl. So they took a digital map of the city and blocked off everything that’s currently single-family residences, everything that’s a historical building, everything that’s green space, working industrial land, and other things people are vociferous about valuing. That left a fairly small percentage of land.
But they showed that if they concentrated density in those corridors, they could add a million people without expanding the city at all, and it would add all these benefits, like better public transit and such. You can dramatically increase the density of places without taking away things people want—and actually adding things they want but couldn’t afford today—because the average suburb isn’t dense enough to financially support a tram or the like. But if you add a dense core that can support that, suddenly even the people around it, in their single-family homes, get the benefit, too.
