Be aware that every flood and every storm is different. For instance, there were some communities in Louisiana that flooded during Hurricane Isaac (2012) but did not flood during Hurricane Katrina (2005). Although Isaac was much weaker than Katrina, Isaac moved very slowly and caused flooding in areas that the faster-moving, stronger Katrina had not.
FEMA is using the latest science and technology available to make your flood maps more accurate with the ultimate goal of protecting you, your home or business, and your community from flood-related losses. FEMA is also working with your local officials to use the information in your new flood map to better plan community development and protect your community from the devastation floods can cause.
