It can be both. I live by an airport. I knew it when I moved. No complaints from me. But, my house backs a golf course. It's zoned permanent green space.

It can be both. I live by an airport. I knew it when I moved. No complaints from me. But, my house backs a golf course. It's zoned permanent green space. A developer bought the land at a discount (because it shouldn't be possible to redevelop it) and it sinking millions into buying local politicians to open the zoning up to condos and commercial use. Damn straight I write my local representatives about that. This isn't just putting a bigger building where one already existed - this is taking a giant green space and bulldozing it all for profit. I'm all for redeveloping underused plots and increasing density where buildings already exist. But removing all the parkland is a no-no to me.
