Cedar Rapids, Iowa, invested $400,000 in a new temporary flood-control system called a Tiger Dam, which officials say will allow them to quickly respond to sudden flooding. The Tiger Dam is a series of 300 orange tubes that can be filled with water in order to create a temporary flood wall. "The main value of the Tiger Dams is speed," said Public Works Maintenance Manager Craig Hanson. Officials say each 50-foot-long tube is the equivalent of 500 sandbags, but each tube only requires one or two people to put in place.
