My article “Off the Grid… and Back Again? The Recent Evolution of American Street Network Planning and Design” has been published by the Journal of the American Planning Association and won the 2020 Stough-Johansson Springer Award for best paper. It identifies recent nationwide trends in American street network design, measuring how urban planners abandoned the grid and embraced sprawl over the 20th century, but since 2000 these trends have rebounded, shifting back toward historical design patterns.
This study measures the entropy (or disordered-ness) of street bearings in each street network, along with each city’s typical street segment length, average circuity, average node degree, and the network’s proportions of four-way intersections and dead-ends. It also develops a new indicator of orientation-order that quantifies how a city’s street network follows the geometric ordering logic of a single grid. These indicators, taken in concert, reveal the extent and nuance of the grid.
It took two decades for HGTV and its ilk to streamline the process of creating design hegemony — to perfect the concept of having multiple shows congeal around the same aesthetic rather than let them exist at the whims of their individual hosts, as was more the case in the 2000s. While previous eras of design (think midcentury modernism) were spearheaded by architects, interior designers, and other tastemakers, in the late ’90s, capital-A Architecture lost interest in the home — deconstructivist ideas and new, high-tech forms were better suited to museums and universities — and a coalition of real estate developers, home improvement and furniture stores, and TV decorators stepped in to take their place. The worlds of high culture and popular consumption in residential design have never been more separate, and, in this critic’s opinion, both suffer as a result.
