Hamburg, Iowa worked with the Army Corps of Engineers to build another 8 feet on their 11-foot levee. That impressive levee held back up to 17 feet of rushing water for 120 days. It cost nearly $6 million, paid for with federal emergency funds.
Hamburg wants to keep the levee. Never hurts to have some insurance, right? Plus, it's already there.
NOPE, says the federal government! The levee needs to be taken down! If you need it again, we'll build it again. And that makes sense to somebody, apparently!
