You use the phrase "trivially fix". If your definition of "trivially" means several decades with the investment of billions of dollars, then perhaps. There are no "trivial fixes" in city infrastructure. Re-zoning only works if there are developers who want to redevelop the land. For existing neighborhoods this means buying dozens of SFH from people who don't want to move. This drives the price of any development up making it unprofitable in most cases. I'm sorry but I can't take you seriously.
When I say "trivially fix" I mean that, if the City/State wanted to fix the problem, they could.
>Re-zoning only works if there are developers who want to redevelop the land.
Developers very obviously want to redevelop the vast majority of LA. The marginal cost of a housing unit is vastly higher than the cost of building that unit. To raise long-term tax revenues, LA could not just legalize redevelopment. They could actually incentivize it.
>For existing neighborhoods this means buying dozens of SFH from people who don't want to move.
The people living in SFH don't want to move exactly because they're not generating enough tax revenue to keep the city afloat (mostly due to Prop 13). Eventually the city will start having to raise taxes very dramatically or declare bankruptcy. That's the entire message from Strong Towns.
The more we put it off, the bigger the impact will be. When your city is effectively long-run insolvent, but you have the ability to change that even if it's politically unpopular (and LA does), then it's "trivially" doable, it's just that people don't want to.
That's not the case in many other cities.
In other cities demand isn't there. People will just leave when taxes go up, and the town will declare bankruptcy. At that point, they will effectively lose most of their population, or people will just live without things like clean water. An example of this happening is Jackson Mississippi, where the water system failed, and the city didn't have the money to fix it. The ultimate solution was just a federal bailout, which is not sustainable if these types of crises become endemic: https://en.wikipedia.org/wiki/Jackson,_Mississippi_water_cri...
In Australia, as zoning changes, developers and owners alike tend to take advantage. If a house was being rented out, they might rebuild as 2-4 homes and rent those out. Otherwise, an owner might rebuild as two semi-detached homes, live in one and sell/rent the second to finance the build. If it is owned by someone who prefers to keep what they have, the next generation might not feel the same. Where there are opportunities, developers (and owners) will find them.
If you change the zoning, people will build to take advantage of that more flexible zoning. I own land in the city, I'd absolutely pursue the financing and coordinate the redevelopment of that land if:
- I could make more money
- if the zoning allowed it.
As it is right now, it'd be profitable, but the zoning isn't there for it.
It's trivial in the sense that it's easier than not doing nothing, because rather than create problems what we've actually done is systematically installed impediments to solutions. We only need to remove impediments, and the solution finds itself.
Obviously that's very simplified, but the point is we've built this Tower of Babylon that exists around property value that is completely optional and just makes everything harder.
