The 15-minute city is a popular urban planning concept that promotes people living close to essential services, and encourages the use of walking and biking. Public transit is sometimes included in the transport mix, preferred to automobiles, which are largely absent.

Developed around 2016 by Paris-based urbanist , the idea of the 15-minute city has spread globally. Moreno subscribes to , or the idea of organizing cities around time including the 15-minute city.

For his work, Moreno has received numerous accolades and negative attention, particularly from the political claiming it will restrict people's .

Moreno isn't the only contemporary urbanist who thinks about time as a key organizing principle for the design of sustainable cities. Variations on the theme include: , the , the , and so on.

None of these, however, have gained as much traction as the 15-minute city. Moreno's work has been plugged into the global : making cities and communities "."

Can one planning concept possibly lead us toward sustainable and inclusive urban futures?

Health, time and the past

One unifying feature of the 15-minute city—or 20-, or 30-minute city—seems to be that by making most everyday activities doable by moving actively over shorter distances, we will become healthier. Research has already shown that .

Another area of consensus appears to be that these approaches, employed globally, will successfully treat our and catastrophic engagement with the environment.

While the 15-minute city might be considered revelatory by some, the relationship between cities and time is as old as cities. In the North American context, before the car and before and during the , amenities and services were located close to where people lived.

Ableism and disability

I think about planning, cities and transportation through a critical ableist and disability studies lens. My lived experience as a parent of a disabled child also informs my .

When considering the 15-minute city, I think about the relationship between —the practices and abilities considered and the social model of disability. The —one of several frameworks—is the idea that disability is produced by discriminatory barriers in society. Ableism produces disability.

The 15-minute city relies on residents' abilities to walk and bike. This raises several questions: What if a resident's body in what is considered a normative sense? What if someone ? What if a resident requires ?

There is no universality to 15 minutes spent in any city. Marginalized people, for example, are more likely to be or .

Planning policy and regulation

Urban planning and city building occur with a regulatory context. The 15-minute city is unlikely to materialize without professional scrutiny and regulatory compliance.

In Ontario, the , the , the and zoning by-laws regulate accessibility in cities. The —which prohibits discrimination—protects the right of equal access to services.

The details of this regulatory environment reveal an emphasis on physical disability and serious in terms of revision and enforcement. It would therefore be foolish to rely on such a relatively inflexibly narrow regulatory environment to make up for any ableist limitations of planning concepts used to shape sustainable, inclusive urban futures.

Educating planners

Disability is often an . Perhaps this reflects a lack of representation of disability, and disabled persons in planning education and professional practice.

Designing sustainable, inclusive urban futures, however, requires inclusive education, thinking, rhetoric and design from the beginning. My challenge to those involved in urban design and planning—including planners, engineers, geographers and architects—is to consider what cities or neighborhoods might look like when with .
