Earlier this week, a mysterious development group brought forward a proposal for five towers near Abernathy Road and Ga. 400 that would rank among the largest mixed-use developments Sandy Springs had ever seen.

Now longtime Atlanta developer Charlie Brown is featured in a story in Friday's Atlanta Business Chronicle with the latest iteration in his long-simmering plans to redevelop the former Gold Kist headquarters site near Perimeter Mall in nearby Dunwoody.

Brown and his company, which bought the site a few years ago and has been refining its plans for some time, appear to be gearing up for at least five towers of their own, including a hotel, residences and offices.

 The planned towers would rise near the State Farm office complex (photo above) –which includes four new towers over the next decade.

We’ve made requests to speak to Brown and his team.

Sites near Ga. 400 and I-285 such as Gold Kist and High Street were awarded massive re-zonings for greater density years ago by county governments.

Those moves contributed to the desires of Sandy Springs and Dunwoody residents to form their own cities for greater local control.

Meanwhile, Boston developer GID is expected in the coming months to unveil renewed plans for the High Street site, another ambitious mixed-use mini-city that was shelved in the wake of the economic collapse.

Many of these mega projects are likely years away and their designs could change considerably — if they even happen in the current development cycle.

But it is a foregone conclusion Dunwoody and Sandy Springs are rapidly urbanizing. Can already choked freeways and surface streets handle more?

In the meantime, maybe Amazon or Uber will figure out drone delivery … of humans.
