Growth like that is a rare boon to have in the coming world of negative population projections and (despite my criticisms) city leadership is meeting the challenge with some of the most aggressive housing expansions seen among any major American city in the modern age. Every political voice in the city is unified in this. For all of our faults, we are a city of transplants who hail from across the entire south and beyond -- no matter where you come from you'll be accepted here with open arms.
With all of that being said, some of the better ways to keep in touch with the local issues are probably the AJC and the Atlanta section of the URBANIZE website[1]. Truth be told, I personally get most of my news by participating in local events. I live in the Midtown area, so I keep an eye on our local event calendar[2] and just show up for whatever feels interesting. I'm actually a very big fan of Midtown -- it's one of the few truly viable places in the state to live completely car-free and being here is what continues to drive my passion for making such a lifestyle accessible to as many people as possible.
