I was in the mood for some light reading before bed earlier this week, and so I pulled out this comparative critique of Euclidean zoning. Many of you are probably familiar with how single-use zoning works. It is the dominant form of zoning in North America and it is predicated on the idea of "everything in its place." Meaning, land uses are best off when they are segregated and put into distinct zones: commercial here, industrial over there, residential in these areas, and so on.
But there are a whole host of arguments for why this is bad cities. Among other things, it makes them less sustainable, because typically you need to drive between zones when you want to do things. It makes them less resilient, because you've now created monocultures. And it also encourages segregation, because if this zone is only for 2-acre single-family lots, then only people who can afford a 2-acre lot get to live there.
I'm sure that many of you are already aware of these arguments. So what I found most interesting from this light bedtime reading was the comparison to the French model of urbanism. One of the key differences in cities such as Paris is that the French have historically preferred to zone for structures over uses. In other words, aesthetics and how buildings look have long been a priority, but what happens inside of them has been less of one.
The result is an incredible mix of uses that makes the city what it is today. And this is perhaps the great irony of Paris. Its visual harmony might make you believe that "everything is in its place." But really things are often all over the place -- as they should be in a city. Adding to this irony is the fact that many single-use cities do not actually appear very orderly, even though they're kind of supposed to by design.
I thought this was an interesting way of looking at these two different models of urbanism. It makes the case that not everything needs to be in its place; maybe it just needs to look that way and the rest will figure itself out.


When I was a kid growing up in the suburbs of Toronto, I never played in the backyard. I played in the streets. That’s where all the kids came together.
We would play baseball in somebody’s driveway, using one of the garage door “squares” as the strike zone. We would play football on corner lots, where it was tackle on the grass and “two-hand touch” on the street. And we would wax our curbs so that we could skateboard them.
None of these spaces were ever really intended for baseball, football, or skateboarding, but we kids repurposed them.
As people, including families, continue to move into urban centers around the world, I have no doubt that the next generation of children will once again repurpose spaces for play. But that doesn’t mean that we don’t have work to do when it comes to properly preparing our communities for people of all shapes and sizes.
One of the most interesting design challenges facing us today has to do with our towers.
Architects have long been obsessed with the idea of vertical villages. Le Corbusier’s Unité d'habitation in Marseille had two shopping streets embedded within the tower that were intended to act as public spines. I don’t know how well they did, but it was a highly progressive idea for the time.
Following on this idea, I was recently watching a TED talk with architect Ole Scheeren (thanks Mariane) and I was fascinated by his obsession with breaking down the raw verticality of towers.
His belief was that, yes, cities are and will continue to become more dense through tall buildings, but that most towers isolate rather than connect people. His work strives to do the opposite.
And this one of the big trends that I think we will see more of in our cites. We will see new forms of urban connectedness and a blurring of private, public, and semi-public spaces. Screw Euclidean zoning.
On that note, I am reminded that I owe the ATC community a post on my predictions for 2016. I hope to get that out shortly.

The Old Urbanist has just published an informative post called “Where Zoning Went Wrong.” In it, he talks about some of the defining characterstics of American city planning and suggests that the delegation of planning authority from states to local municipalities is what has caused many of the challenges that city builders now face.
But before we get into that discussion, let’s outline the characeristics. By way of Edward Bassett’s handbook on zoning (1922), the Old Urbanist outlines 9 characeristics of American planning. They are:
Approval of the exclusion of commercial activity from residential zones
Failure to disapprove of the exclusion of multifamily from residential zones
Extreme deference to localities
Insistence on a “comprehensive” plan
Irreconcilable conflict between planning and zoning
Heavy reliance on legal process as a substitute for sound policymaking
Rejection of aesthetic concerns
Concern with protecting the wealth of well-to-do homeowners
Lack of comparative focus
If you’re a planner or city geek, some of these items will be familiar to you – particularly the first one. Single-use zoning (or Euclidean zoning) is widely criticized as being hugely detrimental to cities, which is why mixed-use is so much in vogue right now. We’ve realized that there are tremendous benefits to creating neighborhoods and precincts where people can live, work, play, and learn. And not just do one of those things.
But one point that somewhat surprised me was number 3: the deference to localities. The Old Urbanist’s argument is that around the world – from Germany to Japan – state and federal governments play a much more active role in city planning as compared to the US. And that the result is a different kind of city. As one example, most other countries don’t have single-family detached-only residential zones. The US does.
Now, you could argue that it’s partially cultural. The US is all about individualism, whereas many other countries around the world have a greater sense of collectivism. But as the Old Urbanist suggests, it could also be because local municipalities are more prone to NIMBYism, which can ultimately lead to downzoning and more restrictive land use policies. Interesting.
It was surprising to me though because I’m a firm believer in strong cities. They drive the economy and I generally believe that they deserve to look after themselves. And so could it really be that they need higher levels of government to keep advocacy groups and community opposition in check?
Immediately I thought of the planning environment here in Toronto and Ontario. The Places to Grow Act, which is largely responsible for the intensification we’re seeing across the region, is provincial legislation. And “the Board” (OMB) that hears appeals arising from the municipal planning level is also provincial. So in other words, provincial decisions trump municipal ones.
Many people believe that the OMB should be abolished. But probably an equal number of people believe that it’s critical to keeping development moving in Ontario. And, given our discussion here, it could be keeping our land use policies in check.
But at the same time, I wonder if there isn’t a way to structure local planning such that it doesn’t succumb to individual interests and instead keeps the greater city building agenda at the forefront. If you have any thoughts on this, I’d love to hear from you in the comment section below.
