There’s been a lot of talk about gentrification recently. Much of it has focused on how bad gentrification is, and how we need diverse neighbourhoods (because that’s why people wanted to move somewhere in the first place). This piece in the New York Times outlines measures some rapidly gentrifying cities in the US are taking to keep older residents from being pushed out by rising property taxes as their area becomes the focus of the up-and-coming. Long story short – Philly has got some pretty decent sounding schemes for keeping its neighbourhoods diverse. Yay for Philly.
