“From Maine to Oregon, local floodplain managers say FEMA’s recent flood maps – which dictate the premiums that 5.5 million Americans pay for flood insurance – have often been built using outdated, inaccurate data. Homeowners, in turn, have to bear the cost of fixing FEMA’s mistakes. It’s unclear exactly how many new maps FEMA has issued in recent years are at least partly based on older data. While FEMA’s website allows anybody to look-up flood maps for their areas, the agency’s maps don’t show the age of the underlying data. Congress has actually cut map funding by more than half since 2010, from $221 million down to $100 million this year.”
