Coastal Flood Maps, otherwise known as Flood Insurance Rate Maps (FIRMs) are used to determine the minimum elevation needed for construction to reduce the chances of flooding, as well as construction methods required in certain zones.

In 2019, Federal Emergency Management Agency (FEMA) released new PRELIMINARY coastal flood maps. These maps may eventually replace the current flood maps which are based on 30-plus-year-old studies.

While FEMA has emphasized that these are only PRELIMINARY maps, the City of Boca Raton wants to ensure all residents and business owners are aware of the potential for a change in flood risk for their property so that they can be more proactive in reducing their flood risk.
