FEMA Changes to the Flood Insurance Rate Map and Policies

Recent Changes to Flood Insurance Requirements

The Biggert-Waters Flood Insurance Reform Act of 2012 (BW-12) is a law passed by Congress in 2012 that extends the National Flood Insurance Program (NFIP) for five years, while requiring significant program reform. Most flood insurance rates will now move to reflect full risk and flood insurance rates will rise on some policies. Please view the links below for additional information on these changes: 

FEMA National Flood Insurance Map Changes

In 2003, with aging flood control infrastructure and extremely outdated flood maps across the United States, Congress mandated that FEMA update the nation’s flood hazard maps. This effort (known as Flood Map Modernization) used the latest data and technology to identify communities’ flood risks nationwide. The most significant change is that the new maps will have an updated base map that will improve the accuracy of floodplain determinations. The new maps will replace the maps from 1996.

As a result of the nationwide Map Modernization effort, many property owners have found that their potential risk of flooding has changed. Pertinent information provided by FEMA regarding the map changes are provided on this webpage.
