Though the two most exciting development projects in Atlanta would/could/should have happened individually, there's no doubt that The Atlanta BeltLine and Ponce City Market enjoy a relationship marked by synergy, a shared spirit and compound momentum. The BeltLine's path through the neighborhoods that surround the Eastside trail almost guarantee that Ponce City Market will become the hub of the east side of town. And the destination PCM is sure to become for both metro Atlanta residents and out-of-town visitors will also drive traffic to the BeltLine's multi-use trails and (eventually) rail transit. But the completion of both projects holds the promise of delivering more than a community gathering place and tourist attraction- it has the potential to serve as a best practices example and catalyst for a new wave of similarly sustainable development all over the city. For now, though, the symbiosis between the BeltLine and PCM is a source of smaller pleasures, like revealing views of the construction progress on the BeltLine from the upper floors of the building. We never tire of dispatches documenting Jamestown's progress on the renovation of the former City Hall East, in both the BeltLine's gallery and the project's own blog. As we all now know, Atlanta will never be New York. But The High Line and Chelsea Market will certainly have some competition.
