Re-chartered in 1917, Kingsport was an early example of a "garden city". Part of it was designed by city planner and landscape architect John Nolen of Cambridge, Massachusetts. It was nicknamed as the "Model City" from this plan, which organized the town into areas for commerce, churches, housing and industry. Most of the land on the river was devoted to industry. Most of the Long Island is now occupied by Eastman Chemical Company, which is headquartered in Kingsport. As part of this plan, Kingsport built some of the earliest traffic circles (roundabouts) in the United States.
