City doesn't have authority to do mandatory evacuations

"I had friends forced out of their homes in the St. Louis area after the Flood of '93, in several cases because of "repeat claims" (they had flood damage in 1973 as well)."

Ahh. It seems then that the city could use the reverse of tax revenue - actual cost to the city/state - as a reason. I'm not motivated enough to go look it up and see if they can lawfully do that at the moment, but it does kinda jive. I'd think they'd also be able to buy up land that was simply hazardous to the public or somehow proclaim it uninhabitable, using environmental guidelines.
