Ch. 1 What is a City?: What the tradoffs might look like

We can visualize the tradeoff between the scale of design and the complexity and spontaneity of a social order as a downward-sloping curve. A sort of “scale-versus-order-possibilities frontier.” In addition to scale and spontaneous order/complexity, a third element I would add to the tradeoff is the passage of time. You can to some extent plan for complementarity, but you can’t really plan for spontaneous complexity and intricacy. [Helpful to bring in capital theory here?] Fortunately, time allows people to some extent to adjust social networks and physical spaces to better complement their own plans, in ways that the designer could not foresee. That is, for any given scale, time lets people figure out novel uses for, or changes to, the space as originally designed. Those unthought-of uses constitute an increase in the level of complexity in a spontaneous order. Over time, then, the frontier can shift outward. Figure 1 reflects these relations: The scale of a structure and the designed or planned uses of the space within that structure are of course two different things. Increasing the dimensions of a room doesn’t necessarily mean the elements that go into its design become more complex. But to keep things simple, Figure 1 treats scale and design as highly positively correlated. [Is this necessary?] Thus, as scale increases so do the designed elements – you move from point A to point B – and together they decrease the potential for spontaneous order. [But think about the tradeoff between scale and order, keeping design constant. Just increasing scale does seem to increase the designed/planned element in a previously undesigned space.] Then, as time passes, the frontier shifts up from AB to A’B, where point B represents the case where the structure occupies100% of the relevant action space. So for any given scale, the […]

Ch. 1 What is a City?: What a city is not (and is)

As Jacobs explains in her book The Death and Life of Great American Cities: Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist…the essence of the process is disciplined, highly discriminatory selectivity from life. In relation to the inclusiveness and the literally endless intricacy of life, art is arbitrary, symbolic and abstracted…To approach a city, or even a city neighborhood, as if it were a larger architectural problem, capable of being given order by converting it into a disciplined work of art, is to make the mistake of attempting to substitute art for life. The results of such profound confusion between art and life are neither art nor life. They are taxidermy.” (1961: 372-3, emphasis original) So how do we avoid turning the results of urban design into taxidermy and killing off a city by planning? I think the short answer is that we avoid it by recognizing that there’s a tradeoff between the scale of a design and the degree of spontaneity, complexity, and intricacy in the resulting social order that the design allows. Now, saying that a city cannot be a work of art doesn’t mean of course that a city cannot be beautiful or that deliberate design can never enhance that beauty. But I am suggesting that beauty that is designed as a work of art is fundamentally different from the undersigned beauty that emerges from a lifetime of experience. The skillfully made-up face of a fashion model and the face of a 90-year-old grandmother are both beautiful, but in profoundly different ways.

Cities are not man-made things

[In this space I’ll be posting quotes, ideas, and excerpts relating to a book I’m writing (thus far untitled), which I might describe as “What I have learned from the economic and social theory of Jane Jacobs.” My hope is to get thoughtful, informed feedback that will be useful in shaping the book.] Architects and planners refer to something called the “built environment” by which they usually mean things such as city streets and pathways and the grids made up by them, buildings of various kinds, plazas, the infrastructure of water and energy inflow and outflow, parks and recreation areas, unbuilt open spaces. Although parts of each of these urban elements were consciously constructed, usually by a team of individuals, the way that they fit together, except in the case of mega- and giga-projects, are not the result of a deliberate plan. Buildings in a particular location, for example, – offices, schools, residences, retail, malls, entertainment, places of worship, research facilities – are of different vintages, constructed by different people for different purposes at different times with different techniques, historical contexts, and sensibilities. But the way they all more-or-less complement one another, their “fit,” is an emergent, unplanned phenomenon. I will refer to these elements collectively as the “built framework,” where the word “built” should not in all cases imply deliberate design. What goes on within the built framework can also be planned or unplanned There are, of course, the activities for which a particular element is intended (most recently, that is, because spaces can have multiple uses over time). A gas station, what we might call a “specialized space,” is primarily for pumping gas, not for seeing a football game, which you do at a stadium. But there are other activities that take place in or are facilitated by a given element, […]

Bike Sharing

My Other Bike is a Public Transportation System by Greg Beato at Reason.com: A bike delivers a strong sense of autonomy, too—stronger even than a car in many ways. It doesn’t, for example, require a license, registration, insurance. You aren’t beholden to routes or schedules. You go where you want, when you want. Unless the bike you’re riding is part of a bike-sharing program. Then your usage is more proscribed. Take, for example, SmartBike D.C., America’s first high-tech bike-sharing program. Launched in August, and, like Velib, funded by an advertising company (Clear Channel Outdoor in this case) in return for the right to advertise on the city’s bus shelters, the program currently consists of 120 bikes and ten docking stations, all of which are clustered within a relatively small radius downtown. For a $40 annual fee, users get a smart card that allows them to unlock a bike from its docking station and start contributing to America’s energy independence. Sounds like a great free-market solution. Right? Greg doesn’t think it’s so great: it’s like you own the bike, except you don’t. You’re not permitted to let someone else ride it. You’re not permitted to put too much stuff in the front basket. (The baskets are for “light goods” only.) You aren’t supposed to ride it in “inclement and dangerous weather.” You have to return it to very specific places at very specific times. If something on your bike breaks while you’re riding it, you aren’t supposed to take it to the nearest bike shop or attempt to make the repair yourself. Instead, you have to call SmartBike’s customer service line and wait for a repair person to respond to your request for help. At least when a bus breaks down, you can abandon ship and take destiny in your own […]

Socialist Cities

So, you think the planners in your area are taking something a little too far? Be glad you aren’t in Venezuela… I wish I could link to the article by Michael Mehaffy in The Urban Land Institute’s May edition of Urban Land titled “Venezuela’s New Socialist Cities”, but ULI doesn’t provide the online edition to non-members. However, I have been able to find some related articles online, which I can share with you. Development of Caminos de Los Indios, the first of five “Socialist Cities” has begun south of Caracas. In his 2007 inaugural speech, Hugo Chavez said, “We need to a system of cities based on federations, federal regions. We need to build communal cities, Socialist Cities.” “Economic power needs to be transfered to these local bodies (“councils of popular power”) – so that we can work toward the communal and social state and move away from capitalism.” The concept is tauted by the government as a way of empowering locals and creating sustainable places for the 1/2 million residents. In Nov 17, 2007’s Washington Post, Ramón Carrizales, Venezuela’s housing minister is quoted “A city that’s self-sustainable, that respects the environment, that uses clean technologies, that is mostly for use by the people, with lots of walking paths, parks, sports areas, museums and schools within walking distance.” However, many environmentalists are appalled, since these cities will be build in the wilderness, requiring roads and infrastructure to these newly deforested locations. Not only that, many rural residents will be forced to resettle into the “Socialist Cities.” The history of these sort of projects are dismal. From the Washington Post article Chávez’s ‘Socialist City’ Rises: “The majority of socialist cities that were built in socialist countries failed,” said Maria Josefina Weitz, an urban planner in Caracas. “When you create something by […]

Markets for Parking

Matthew Yglesias: Parking How much will they pay? Well, it’s hard to know in advance which is why you need markets. But that’s what you should have — as much parking as the market will bear. Not government-mandated parking, and not government-provided free or discount parking. Let people build garages and if it’s more economical to provide less parking, let there be less parking. SFGate: SFpark would micromanage city’s scarce spaces As SFpark is envisioned, parking rates would be adjusted based on time of day, day of week and duration of stay. People would be able to pay not just with coins, but with credit cards, prepaid debit cards and even by cell phone. If a meter is set to expire, a text message could be sent to the driver. More time could be purchased remotely. It’s a step in the market direction for public parking spaces, but why not privatize all those spots? chicagobusiness.com: City links CTA improvements, higher parking fees While proceeding with these plans, the city also is privatizing operation of its thousands of parking meters. That could provide the city with a substantial cash infusion.
