Identify if your property is in the floodplain

  1. Visit the FEMA Floodplain Map
  2. Enter your full address in the search box (including city, state, zip).
  3. If you are in the blue or red/blue stripe section, you are in the 100 year floodplain.
  4. The map results will show sections in
  • Blue: floodplain 
  • Red AND Blue Striped: floodway
  • Orange: not regulated floodplain
  • Orange and Gray Striped: protected by the levee. More information

If you are in the blue or red/blue stripe section, you are in the 100 year floodplain.
