Take a look at this tweet I came across yesterday:

On the left is a picture of some crowded and dense city at, I presume, the turn of the 20th century. And on the right is a picture, today, of your generic suburban city with lots of cars, a broad street and auto-oriented signage everywhere.
As the captions say, the city on the left is what modernist architects like Le Corbusier and powerful city builders like Robert Moses were trying to fix. What we ended up with, as a result of these efforts, is the city on the right. Now, today, we–architects, planners and urbanists–are all trying to correct what we see as a huge misstep in the way we designed and built cities.
But is it really an anomalous misstep or is it simply a preferential pendulum that swings back and forth from generation to generation? One generation thinks cities are dirty and evil and that they need to be evacuated. And then the next generation loves them and wants to move back into them, which is what’s happening today.
Dogma–particularly when it comes to cities–takes a long time to percolate through the system. Le Corbusier was espousing his city building ideals of “towers in parks” in the 1920s. That’s when he proposed to demolish 2 square miles of Paris (Plan Voisin) and turn it into what most people today would think looks like a New York public housing project.
But for these new ideas to take hold, young architects, planners and builders first need to become indoctrinated in school or wherever they’re learning the ropes. Then, they need to get out and start practicing and mature to a point where they’re starting to influence and control substantial city building decisions. That’s why, I think, Le Corbusier’s ideas of the 20s really only became widely accepted as planning principles in the post-war years.
Because of this though, I sometimes wonder if I too am just following the natural cycle of changing tastes. When I went to architecture school, we were taught that public transit is more efficient than private cars, density is good for the environment and for economic development, and that Le Corbusier was generally a crappy city builder. And if you’re a regular reader of this blog, you’ll know that that is generally the view I take here.
But when I ask myself this question, I think of a few things. First, if you look at the urbanization of ancient cities, they were always organized around strong public spaces. The desire for human beings to be able to walk around, conduct business and socialize with each other is not a new phenomenon. And our post-war planning ideals put a strain on that.
Second, take a look at the world and what’s happening. The majority of people now live in cities and we’re continuing to urbanize at a frenetic pace. Shenzhen in China went from a population of just over 300,000 people in 1979 to over 10.5 million people today. That is the pace of urbanization that city builders need to deal with. It’s unprecedented.
And to even begin to make that manageable, I don’t think we can continue to build cities like the ones on the right side of the picture, above. It’s unsustainable both environmentally and from a mere space planning standpoint. There simply isn’t enough room.
So call me a product of the times, but I just don’t see our current planning goals as one side of a swinging pendulum. I see them as a return to what cities have always been about: a place for people to interact, socialize and generate wealth.
If you’re into cities, then you’re likely familiar with the Baron Georges-Eugène Haussmann.
He was Napoleon III’s urban planner and the man responsible for the Paris we all know and love today. Those broad avenues radiating from the Arc de Triomphe are his doing. His plans transformed Paris from a medieval city into what was considered to be, at the end of the 19th century, one of the most modern cities in the world.
What spurred this post is an exhibition currently on display at the National Gallery of Art in Washington. It’s on the photography of Charles Marville, who was, interestingly enough, initially commissioned to document Paris before Napoleon and Haussmann “destroyed” it.
In reading NPR’s summary, I was amazed to learn about the meticulous detail that went into the redesign of the city, which went all the way down to the gas street lamps that were rolled out following the “Haussmannization”of Paris. In fact, so much thought went into the appearance of these street lamps that their heights were actually modulated to match changes in street elevation; the effect being that as you looked down an avenue, the street lamps always appeared even and harmonious despite any ups-and-downs in the road.
But beyond street lamps, the exhibition also got me thinking about urban renewal as a broader concept. Today, I suspect that most people would consider Haussmann’s interventions to have been a positive thing for Paris. Before these changes, Paris was a cramped and crumbling medieval city.
However, while in retrospect these changes might seem positive, Parisians at the time hated what was happening to their city. The entire place was under construction. And if you’re a fan of Impressionism, you’ll know that many artists at the time began lamenting about the regularization of Paris. They yearned for the visual variety that once characterized the city.
But as any developer will tell you, change is not something most communities tend to embrace. In fact, it’s human nature for us to down play positives and play up negatives when faced with uncertainty (see Prospect Theory).
And sometimes it’s merited. Fast forward to 1925 and you have yet another audacious Frenchman trying to destroy and rebuild Paris: Le Corbusier. Come to think of it, I wonder if he thought of himself as the next Haussmann. He certainly thought of himself as the man responsible for ushering in the next wave of modernity.
But while he didn’t execute on his Plan Voisin in Paris, he certainly left his mark on cities all across the world. The plan he intended for Paris, was more or less what we used to clear slums in a lot of cities. However it turned out to be a complete failure.
So I guess the moral of the story is that some change is good and some change is bad. But most of the time it’ll seem bad at first, making it hard to tell which is which.
