This Vox Future Perfect article examines how compact, infill development can reduce infrastructure costs, improve fiscal sustainability, and create stronger communities.

The article also features John Zeanah, who explains how Memphis is shifting its planning strategy to focus investment in established neighborhoods and corridors—demonstrating how thoughtful growth can reduce the long-term costs of sprawl while creating more resilient communities.
