AECOM conducted the Climate Change Study for FEMA to analyze potential long-term implications of climate change on the NFIP. The climate change impact assessment includes all 50 states, as well as consideration of the U.S. territories. However, since the concern is impact on the NFIP as a whole, it is recognized that not all regions have the same relative significance. A detailed region-by-region assessment of climate change was not intended. Major attention, therefore, was given to areas of greatest population and the largest inventory of at-risk properties.
FEMA intends to use the findings of this study to assist in the development of recommendations addressing the impacts of climate change and future development on Flood Insurance Rate Maps (FIRMs).
