On June 30, 2008, the Federal Emergency Management Agency (FEMA) released preliminary Flood Insurance Rate Maps (FIRM) to communities in Onondaga County for public comment. Since that time, the maps have gone through a period of due process and are slated to become effective on November 4, 2016. The maps provide updated information about the community’s flood risk, inform insurance rates and purchase requirements, and help property owners make decisions about how to protect themselves and their properties against future flood events. The FIRM and the associated Flood Insurance Study (FIS) are the basis for each community’s floodplain management measures.

Some properties in Onondaga County, may, for the first time, be included in a high-risk flood zone, known as the Special Flood Hazard Area. This may result in those affected homeowners being required to purchase flood insurance. Flooding is the number one natural disaster in the United States. It is vital that property owners understand their current flood risk, and take advantage of tools or programs available to make their property and community safer and stronger against future flood risk.

Additional information on mapping is available on FEMA’s Map Service Center and flood insurance information can be found on FloodSmart. You may also contact a map specialist at the FEMA Map Information eXchange (FMIX) at (877) 336-2627. Or attend a Flood Risk Open House
