Flood, Hurricane Katrina | featured news

Isaac was on the verge of ballooning into a hurricane Tuesday that could flood the coasts of four states with storm surge and heavy rains on its way to New Orleans, where residents hunkered down behind levees fortified after Katrina struck seven years ago this week.

A federal judge ruled Wednesday that the Army Corps of Engineers' failure to properly maintain a navigation channel led to massive flooding in Hurricane Katrina, a decision that could make the federal government vulnerable to billions of dollars in claims.
