If there's a part of Atlanta that's seen as little investment as southwest Atlanta, it's northwest Atlanta. Running through that long-overlooked part of town is Proctor Creek, a polluted waterway stretching from Vine City and English Avenue to the Chattahoochee River. It's an untapped asset that, thanks to a bold plan by some private developers, could become the Emerald Corridor, a linear park and bike trail flanked by smart development. The project has the blessing of the federal government and is far along in discussions with City Hall, which is providing some land. Much like the Beltline or every other project that aims to improve an area, it could spark questions and concerns about public investment and gentrification. But it has great potential to revitalize the area and will be something to watch unfold.
