The Federal Emergency Management Agency, or FEMA, has an online tool that makes it easy to see if your address is in a flood zone. The Flood Map Service Center shows information like flood zones, floodways, and your own home’s risk level. There’s also topographical and infrastructural information about features like levees, coastal barriers, and the base flood line. The map can seem confusing at first until your familiar with it. FEMA maps do undergo periodic updates. You’ll more than likely need to visit the flood center multiple times to receive the most correct data. With new construction and changes.
