In the aftermath of Hurricane Katrina and the severe flooding that resulted, the Federal Emergency Management Agency (FEMA) started improving flood zone maps as the first step toward improving flood risk identification and obtaining flood insurance.
The National Flood Insurance Program (NFIP) oversees flood zone maps, which can be located in your local community's Flood Hazard Boundary Map or Flood Insurance Rate Map. FloodSmart.gov provides information about obtaining flood insurance for commercial properties and the importance of knowing your flood zone.
Data on your flood zone will help identify the risk of flooding in your area, and that will impact your ability to obtain flood coverage.
