If we want more density and less sprawl, where will the land come from?
Re-zoning exclusively single-family home space is a rising idea, and feasible, given the example posted earlier on PT from Houston.
Christopher Pollen writes in The Tyee “Imagining City Life After the Car“.
Across North America today, precious urban housing space is languishing right under our noses — or more precisely, under our wheels.
In the City of Vancouver alone, it’s estimated that over 30 per cent of all land — worth an estimated $48 billion — is tied up by our roads, parking lots and alleys. This vast urban “greyfield” constitutes the largest tract of un-built space in many cities, raising exciting questions about how it could be used to make urban density liveable, family friendly, and maybe even more affordable. . . .
. . . . We seldom think about it, but our roads and alleyways occupy enormous tracts of valuable land. Consider: the City of Vancouver has more than 1,400 linear kilometres of roadway, including over 1,000 kilometres of local roads and 650 kilometres of driveable lanes and alleys; a typical street in Vancouver is 66 feet wide, while larger arterials are 80 feet.
And really, it’s not such a new idea, as this PT post from 2013 shows.
