Re: Ask HN: How would you fix cities?

On a heavily-used block with tall buildings on both sides, here's a recipe that will work well: 1. Dig up the street and sidewalks, going down 60-100 feet. 2. At the bottom of this pit, drive in piles if you haven't yet hit bedrock. 3. Build a box, about twenty feet high, to run plumbing, power internet, and other utilities 4. On top of that box, build another one for a train. 5. On top of that box, build another one…

Has anything resembling that ever been implemented on a wide scale?

That's not easy. Take public transit, for instance. Arguably, that would be a good thing to change - supply fast, frequent, convenient public transit. But how would you do it? US cities (with few exceptions) have reached a stable equilibrium where cars are necessary because there's no convenient transit, there's no transit because the city doesn't have the density to make it worthwhile, and it can't have the density…

Of course the U.S. has the chicken-and-egg problem, but public transit is my vote if I could wave a magic wand. I am tired of car cities: more pollution, obesity, rage, and sprawl.

I agree, and it seems like many people share our feelings, which makes sense when you look at how the most desirable cities according to our views are getting more and more expensive. Of course there aren't many of these cities in the US.

The solution I'd love to see is giving these cities more competition. Let's try to revitalize old cities like Baltimore and Cleveland to give people more affordable options. I've heard Pittsburg is having some success with this kind of thing.

Alas, not yet, no. (But that alone isn't a good reason not to try.)

It also leaves you a one-block-long tunnel for a train, and another for a road, for years until you get the blocks around it done - probably for decades until you get a system that goes anywhere.

Sure, but you have to start somewhere. Why waste money digging up the same street over and over, as most cities do? It seems more efficient to do it once and be done for a long time thereafter.

Also, you could easily imagine doing this to a part of the block that's up on a hill - Seattle and SF have a lot of areas like this. It would make piping existing traffic into and out of those transit sections easy.

Put a limit (e.g. 1) on the number of residential properties any individual person can own within city limits and make them (residential properties only within city limits) illegal to buy for a corporation. A lot of people might think 'socialist' and I may have said the same a few years ago but having seen issues up front, lives (within some cities) are being completely ruined with the hoarding and speculation.

So no-one can move to this city unless they can afford a mortgage there with it's associated closing costs?

Presumably people could still rent out their own property, as long as the owner is an individual who either lives on the premises, rents (but doesn't own) another place in the city, or lives outside the city entirely.

Here in Seattle, we spend $$$$ buying a tunnel boring machine, bore a transportation tunnel for a section, and then ...

... cut up the boring machine for scrap!

It's like setting up a giant printing press to print a newspaper, and then printing 10 copies.

I'd make them much more walkable, by blocking off certain short sections of streets from car traffic during certain hours. Many european cities do this, and it works well.

Adelaide has been building up walkable laneways that span the whole city to move in that direction. They are permenantly foot traffic only and they are hands down the best places to wander in the city. To eat outside is so nice when there are no cars shooting past, you don't notice how much noise they add until they are gone entirely.
