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In 2003, with aging flood control infrastructure and extremely outdated flood maps across the United States, Congress mandated that the Federal Emergency Management Agency (FEMA) update the nation’s Flood Insurance Rate Maps.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 regarding the map changes are provided on this webpage.

FEMA's new Flood Insurance Rate Maps will become effective March 2, 2016. Lower Merion Township will host a public workshop to inform property owners about how these changes may impact them on Tuesday, January 19, 2016.
