Why the rush to increase the population in a water-poor, earthquake prone region? It seems crazy to me, and “money” seems an insufficient answer. California as a whole seems less than sustainable over the next 50 years, so maybe planning should aim in another direction? Instead of inducing people to live there, build competitors in less seismically unstable regions that have access to fresh water that isn’t just about gone.
I appreciate that every place is subject to some kind of disaster, but massive, regular earthquakes liquefying soil is second only to massive floods for destructive capacity. It’s also true that if for example you live near a Great Lake, you have water. In terms of risk to people and infrastructure, tornadoes are pretty minor compared to earthquakes and drought.
