The Federal Emergency Management Agency (FEMA) is using advancements in digital mapping technology to redefine the country’s flood zones. As a result, many homeowners are being required to buy flood insurance for the first time, while others who have had coverage for years are being cleared to drop their flood policies altogether.

The changes are occurring as part of a multiyear plan by FEMA to digitize its Flood Insurance Rate Maps to make them more accurate. The process began in 2003 and FEMA is projecting that 65% of the land in the country (92% of the population) will be covered by the new high-tech maps by 2010. According to FEMA officials, the accuracy of the new mapping technology has vastly improved and allows for more precise information to be used in determining special flood-hazard areas.
