> I understand the "build more" concept, but a city (any city) shouldn't grow too fast. There's a huge risk in growing too quickly.

Well, it's pretty clear from the explosion in housing prices that it's not growing nearly fast enough. I'd love to see some citation as to what "too fast" is and why you think SF is at risk of hitting that number.

> SF's infrastructure doesn't seem that it can handle more people. traffic is bad. Restaurants are full (have you been to a brunch?). Buses are full. More homeless than ever.

More housing = more people = more revenue. That revenue turns into more infrastructure, more restaurants, etc. In fact more density makes infrastructure more economical to operate on a per capita basis. Think Hong Kong.

Part of the reason there's more homeless people is they can't afford houses, which building units would help alleviate.

> Letting the price rise, so people/companies will go elsewhere seems like an okay strategy.

That's not a very free-market attitude!

The cost of upgrading infrastructure in a busy city is enormously expensive. San Francisco is on a peninsula with no room at all to expand outward. The only solution is to build up and that’s a real problem in an area prone to earthquakes.

Plus there are a lot of people that like the character of their neighbourhood and don’t want to live in an apartment building. It isn’t their fault that SF became the global tech capital.

So having more people to split that cost with would help! To be clear Hong Kong island is far harder to build on.

They’re also not entitled to that. In a democracy the many decide.


> They’re also not entitled to that. In a democracy the many decide.

Actually, yes they are. San Francisco is a participatory democracy. Between a large # of ballots voted for each November, we elect our board of supervisors and attend supervisor meetings to tell them how to vote.

If people don't vote, well, that's their fault.


Nobody is entitled to a view or a property value. It’s not written down, it’s not codified, it’s not an entitlement. It’s a side effect of poor policy.

I say that as someone who owns property in San Francisco.


The many struggle to organize themselves as effectively as the few. This is how it’s always been in politics. I’m not aware of any recent development that would change that dynamic.


In a democracy the many decide.

In a democracy the people who inhabit a place decide. Not the people who want to inhabit it. That's not democracy, it's colonialism.


lol, that's not colonialism.

  Colonialism: the policy or practice of acquiring full or partial political control over another country, occupying it with settlers, and exploiting it economically.
However, with that in mind, I'm alluding to the kinds of people in a city like San Francisco. The older, rich, land-owning class tends to be very activist and tends to vote. The younger, less-wealthy, renter class tends not to vote. Therefore, the needs of the few are outcompeted by the needs of the many.


> They’re also not entitled to that. In a democracy the many decide.

We did decide, and continue to do so in supervisor meetings and in the ballot box. You might want to read up on federalism.


Basically all of Japan is earthquake prone, they do just fine. The building technology is there.


> The cost of upgrading infrastructure in a busy city is enormously expensive. San Francisco is on a peninsula with no room at all to expand outward. The only solution is to build up and that’s a real problem in an area prone to earthquakes.

People always ignore this fact. Infrastructure isn’t free. When all is said and done the Central Subway extension will likely have cost over $2bn for 1.7 miles of subway. [1] The new transit center cost $2.2bn [2]. Rebuilding 1/2 of the bay bridge cost $6.5bn. [3]

Consider that money for all of this is artificially restricted by Prop 13, and by California being a net-giver state, paying about $40bn per year more to the fed than we receive back, effectively being a piggy bank for poorer states.

Many commenters with a lot of hatred for San Francisco’s unique brand of dirext democracy are sadly OK with overruling the expressed will of the people not to turn our home into New York just so some tech billionaires can sell more banner ads.

Well that's just inefficiency or graft. The rest of the world is able to achieve far more for far less cost.

Who's our? Generally voters tend to be older, wealthier and landowners. The large pile of younger, less wealthy, more transient renters isn't represented well. I don't think the outcome means the system works.


Furthermore, it’s not even a big city problem. California High Speed Rail has been an immensely expensive project so far, an order of magnitude more than comparable systems, and the only segment built is in Central California, not the expensive coasts.

Citation?

That’s how democracy works. If you don’t vote, you don’t have a voice.

All costs below are in $USD nominal per mile of fully-underground subway system.

NYC subway extension, east side: $3.7B per mile.

SF Central subway: $928M per mile.

Tokyo: $400M

Beijing: $240M

Berlin: $327M

Naples: $194M

Milan: $175M

This is backed up by a Citylab analysis:

  Alon Levy at Citylab shows approximate range of underground rail construction costs in continental Europe and Japan is between $100 million per mile and $1 billion. Most subway lines cluster in the range of $200 million to $500 million per mile.

  The US has a range of subway construction costs of $600 million to $2.6 billion per mile. The US median price cluster is $800 million to $1 billion per mile.
And of course plotted in Tableau [5].

Indeed.

In an optimistic world, sure.

It can also be that you build a bunch of building. Then, there's an economic downturn, and SF is fucked and left with abandoned buildings.

There are cities that fell into this trap.

I'm not saying it will happen, but it can happen.

Growing slowly is a good way not to push yourself into that corner.

How slow? I dunno. I hope there's an expert that can evaluate it.
