  By: David A. Smith    [Continued from the preceding Part 1, Part 2, Part 3, and Part 4.]   As established in the earlier four parts of this post, modern cities depend on verticality – without it, the city’s horizontal expansion would overtax all natural resources, overload any infrastructure, and despoil the urban environment, […]
