David King: By This Logic, Perhaps the Whole Thing is Flawed:
“Second, Rail Authority Chairman Dan Richard explained omitting Anaheim based on the cost of travel time savings:
Electrifying and improving the Los Angeles to Orange County route would cost $6 billion and save only 10 minutes of travel time, said rail authority Chairman Dan Richard.
“Why would we do that, pay $600 million per minute?” he said in an interview Friday.
Let’s do the math here. The project is justified on travel time savings, and the Chairman has now said that $600 million per minute is too high a cost. At about $70 million, the current project needs to save more than two hours (116 minutes) to justify the expense if each minute is worth $600 million. Yet Richard says $600 is too high, but by how much? The current (new) business plan offers about 2 hour and 40 minute service from San Francisco to Los Angeles on some routes. (How travel times didn’t increase with the blended plan is still a bit of a mystery.) So, can you get from Union Station to San Francisco in less than or equal to 4:40 under current technologies? Yes you can. Flying is faster, even with airport hassles (Try Burbank to Oakland!). Driving is a bit longer, but is much more likely to get you exactly to your destination resulting in similar door to door times.”
“In her celebrated book The Death and Life of Great American Cities, which first appeared in 1961, Jane Jacobs argued that zoning, the concept on which the entire American planning system is based, is misconceived. Zoning leads to a disaggregation of the many functions of the city so that people live in one part, work in another, spend leisure time in a third, and shop in a fourth. Whole swaths of the city are thereby deserted for large parts of the day, and the fruitful interaction of work and leisure never occurs.
Zoning contributes to the dereliction of the city when its local industries die and ensures that the central areas are not places of renewal, but at best museums and at worst vandalized spaces no one can use. In successful cities like Paris, New York, and Rome, workshops, apartments, offices, schools, churches, and theaters all stand side by side, with houses borrowing walls from whatever building has a boundary to spare.
The complaint against zoning is surely right. But it is not a complaint against planning. The great planning disasters, some of which have been studied by Peter Hall, owe their negative impact at least in part to their scale. When the layout of a town is conceived from a master plan, the possibilities for disaster are legion.”
