The Federal Emergency Management Agency (FEMA) has issued preliminary maps showing revisions to the 100-year floodplain, which has a 1% chance of flooding in any year. FEMA has released preliminary maps for flood areas along coastal, marine waters and freshwater rivers, streams and lakes of Jefferson County. These maps will help community officials and local residents identify flood risks and when adopted, will be used for flood insurance, land use and development decisions.
