Re: ratios of green to developed space

Philadelphia, the original "Greene Countrie Towne," was founded under
William Penn's Charter that required one acre of green space for every four
acres of development, which makes for a very pretty city.

It lasted for many years, until developers found a loophole and annexed the
surrounding farmland into the city limits. When you bought a parcel
downtown you got a corresponding chunk of open space out in the
hinterlands. We've been fighting to get the original regulations back ever
