Changes to the Flood Insurance Rate Map
FEMA National Flood Insurance Rate Map Changes 2011-2012

In 2003, with aging flood control infrastructure and extremely outdated flood maps across the United States, Congress mandated that FEMA update the nation’s flood hazard maps.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.

On February 23, 2011 a presentation of changes to the National Flood Insurance Rate Maps was held in the Board Room of the Township Administration Building. A PDF version of the presentation is available (4 MB).
