This isn’t actually a post about transit. It’s about land use. But we’ll get there in a second. Enrique Peñalosa, the former mayor of Bogotá, Colombia, is responsible for one of the most widely-shared quotes in the urbanist world: “An advanced city,” he said, “is not one where the poor use cars, but rather one […]

    One of the most controversial recommendations from Seattle’s affordable housing task force, or HALA, was to reform zoning laws that only allow single-family homes in certain neighborhoods. That was always going to be a challenge—as Sonia Hirt argues in her history of American zoning, Zoned in the USA, prioritizing and protecting single-family-home-only neighborhoods

“The automobile tragedy is one of the most serious…man-made assaults on the human body,” wrote Ralph Nader in 1965. “It is a lag of almost paralytic proportions that these values of safety…have not found their way into legislative policy-making for safer automobiles.” Those words come from the preface of Unsafe at Any Speed, an expose

What City Observatory did this week 1. Let’s talk about neighborhood stigma. Daniel Kay Hertz reviews some of the literature on the interplay between a neighborhood’s reputation and its disadvantage—and finds a surprising reversal in the conventional understanding of the issue.

Back in June, we catalogued how riders weren’t really abandoning buses—buses were abandoning their riders, with significant cuts to service in many metropolitan areas that appeared to be driving declines in ridership. Further analysis of transit data since 2000 suggests that bus riders may have another problem: not only are there fewer buses on their

My hometown, Chicago, is having a fight over words: in particular, “Chiraq.” That’s a portmanteau of “Chicago” and “Iraq,” which is meant to analogize the city not to that country’s rich cultural heritage, or extreme weather, but to its war. The name seems to have come from a South Side rapper, but has since been

What City Observatory did this week 1. Our old planning rules of thumb are “all thumbs.” Joe Cortright argues that many of the heuristics that have guided urban planning for decades, such as “wider streets are safer streets,” and “faster traffic flow is always better,” have long outlived their usefulness. We offer five of these outdated

What City Observatory did this week This week, we ran a three-part series on what we mean by “housing affordability.” 1. In The way we measure housing affordability is broken, Daniel Kay Hertz writes about the problems with the most common way “affordable housing” is interpreted: as housing costs that make up no more than

Over the past two posts, we’ve argued that the most common measure of housing affordability – whether someone is paying more than 30% of their income – has a lot of serious problems. For one, housing costs are only one facet of overall location costs: if you move from the city to the suburbs for
