By Paul Krugman:
The disaster in Houston is partly Mother Nature — natural disasters will happen sometimes whatever we did — but with a powerful assist from human action. Climate change definitely made such an event more likely; beyond that, Houston’s total lack of zoning, complete failure to limit the amount of land paved over, made it much more vulnerable than sheer geography required.

But this isn’t a simple parable where hostility to government intervention is the villain. In general, I have contempt for “both sides” arguments; given the corruption of modern American conservatism, on most issues there is a huge asymmetry between left and right. When it comes to land use policies, it really is true that both sides get it wrong.
Having no zoning, no control, can be disastrous — which is what we’re seeing in Houston now. But all too many blue states end up, in practice, letting zoning be a tool, not of good land use, but of NIMBYism, preventing the construction of new housing.
In fact, liberal (in the non-political sense) land use policy is probably the secret behind Texas economic growth: the state doesn’t offer high wages, but it does offer cheap housing even in huge metro areas. Compare real housing price evolution over the decades in Houston and San Francisco (sorry, the blue state is the red line and vice versa):
What we need is effective land-use regulation that doesn’t strangle housing construction. But how do we get there politically? No idea.
