IS YOUR HOME IN THE NEW FLOODPLAIN? Floodplains are changing nationwide due to global warming, including those in Austin. Here's how to check if your property is in the new floodplain: Go to www.ATXFloodPro.com Click the "I want to" button, then "Explore Atlas 14 Changes" Enter your address and click on "Search." Areas shown in blue are mapped within the 100-year floodplain currently. Purple areas indicate the interim 100-year floodplain, based on Atlas 14 and our new understanding of flood risk in Austin. To print or download a map of your property, click the "I want to" button again and select "Print a Floodplain Map." Check the circle next to "Custom Map" and then the circle next to "Atlas 14."
