That's become a problem in some areas, such as Louisiana, where Gov. John Bel Edwards' office has estimated that last month's flooding damaged 60,646 houses. FEMA says 109,398 people or households have applied for housing help and 25,000 National Flood Insurance Program claims have been filed," Drew Broach reports for The Times-Picayune in New Orleans. An estimated 18,873 houses were damaged by the flood and 50,750 people were caught in the flood or lived in a flooded home, according to DisasterMap.net.

Kathy Schaefer, an engineer who spent 10 years drawing those maps at FEMA, told Joyce. "All of the mapping had to be based on the existing conditions (at the time they were drawn, or many years earlier)." She said "those conditions were rainfall and flooding statistics from the past. Sometimes decades in the past."
