Emminent domain wouldn't work in this though... would be kinda hard to justify increased tax revenues from a few thousands lots where there's no business (all the people are gone) and no business wanting to build on top of land infected with toxic Superfund site hazardous waste chemicals...
No, wait. I bet we could easily convince a big chemical plant to build there or the existing chemical plant that blew up could just do some expanding! There, all settled. Kick 'em out!
