Flood Hazard Areas
Floodplains are areas of land susceptible to inundation by floodwaters. Special Flood Hazard Areas are floodplains that adjoin a river, stream, or other inland or coastal waterway that are inundated by water during the 1% annual chance flood (100-year flood). The 1% annual chance flood is a flood event having a 1% chance of being equaled or exceeded in magnitude in any given year. Special Flood Hazard Areas are considered a Wetland Resource Area under the Massachusetts Wetlands Protection Act and are depicted on Federal Emergency Management (FEMA) Flood Insurance Rate Maps (FIRM) as Zones A, AE, AH, AO, AR, A99, V and VE.

Preliminary Flood Insurance Rate Maps for Suffolk County Now Available
FEMA is in the process of updating FIRMS (Flood Insurance Rate Maps) for coastal areas across the country. The Preliminary FIRMs for Suffolk County are now available on FEMA’s website. A statutory appeal/comment period is estimated to take place during the spring of 2014. During the appeal/comment period, the public, or any interested party, may comment on or appeal the mapping analysis by presenting scientific or technical data supporting their position.
Following resolution of any comments or appeals received, the FIRMS will go through final quality reviews. Once the maps are finalized the City will hold additional neighborhood meetings to address the impacts of the maps. The maps are anticipated to become effective for insurance and building permitting purposes in July 2015.
To find out if your property will be affected by remapping, first find your panel number, and then search the Preliminary Flood Hazard Map page for your panel number.
