For how much it would cost, perhaps it's not necessary. This is a freak event that's at least a 1 per century kind of thing (probably more). It'll cost around 1-2 billion to clean it all up. The diversion thing will cost a ton more than that. Spend some money making it more difficult for the banks to overflow. That's about the extent I think would be necessary. Something that would help to prevent most of what happened in 2005 basically.
