Is the tiny little neighborhood the city of the future?

Why the hyper-local 15-minute city' is gaining ground in urban planning circles

At first glance, O'Fallon, Illinois, has little in common with Paris, France. Paris has its world-class museums and cream-colored Haussmann-style apartment buildings. O'Fallon, an outer-ring suburb of St Louis with a population of 32,000, has a collection of squat brick buildings settled around a little-used freight rail track in its city center, and a proliferation of mid-century ranch homes on the blocks beyond.

On the other hand, there are macarons for sale at O'Fallon's Sweet Katie Bee's organic bakery cafe. And last year, when O'Fallon adopted a 180-page master plan to guide its development for the next two decades, it chose the same organizing concept" that Paris's mayor, Anne Hidalgo, made the backbone of her 2020 re-election campaign: the 15-minute city.
