How were the impacts of Hurricane Sandy factored into the ABFE information? Where do I get the ABFE maps?įor most communities in the region, the ABFE maps have now been replaced by preliminary FIRMs as the most recent flood hazard information available from FEMA. An historical archive of all ABFE information released is available through the FEMA Best Available Data archive page. The ABFEs are based on the partially completed coastal flood study underway before Hurricane Sandy. Information about the methodologies, assumptions and data sources used to develop the Advisory information is available through the New York/New Jersey Coastal Advisory Flood Hazard Information Development Report. ABFEs are provided to communities as a tool to support them in recovering in ways that will make them more resilient to future storms.ĪBFE maps were developed for the New Jersey/New York coastal region following Hurricane Sandy because in some cases, the effective FIRMs were more than 25 years old and did not accurately reflect coastal flood hazards in the area. In some cases, due to the age of the analysis and the science used to develop the effective FIRMs, FEMA determines there is a need to produce ABFEs. ![]() What are Advisory Base Flood Elevation (ABFE) maps?įollowing large storms, such as Hurricane Sandy, FEMA performs an assessment to determine whether the 1% annual chance flood event, shown on the effective FIRMs adequately reflects the current flood hazard. More information about these products is also available through the FAQ below and in the Document Library. Because existing Flood Insurance Rate Maps (FIRMs) for these areas were developed more than 25 years ago, and the updated FIRMs were not finalized, FEMA developed Advisory Base Flood Elevation (ABFE) maps in late 2012 and early 2013 to support reconstruction efforts using the partially completed flood study.įor most communities in the region, the ABFE maps have now been replaced by preliminary FIRMs as the most recent flood hazard information available from FEMA. An historical archive of all ABFE information released is available through the FEMA Best Available Data archive page. Prior to Hurricane Sandy, the coastal flood study underway for the New Jersey and New York coastlines was only partially complete. Advisory Base Flood Elevations (ABFE) Frequently Asked Questions
