Flood hazard maps, also called “Flood Insurance Rate Maps” or “FIRMs” are used to determine the flood risk to your home or business. The low- and moderate-risk zones are represented on the maps by the letter “X” or an “X” that is shaded. The high-risk zones will be labeled with designations such as “AE”.
A floodplain is the part of the land where water collects, pools, and flows during the course of natural events. Such areas are classified as Special Flood Hazard Areas (SFHA), and are located in a 100-year flood zone. The term "100-year flood" is a little confusing. It is the flood elevation that has a 1- percent chance of being equaled or exceeded each year; it is not the flood that will occur once every 100 years. The likelihood of a flood occurring within a 100-year stretch of time is very, very high, but there’s no way to predict when the next flood will occur – or the one after that.
It's a good idea to have your flood insurance through the company that provides your homeowners' or your business' private insurance. If your agent does not write flood insurance or you do not have an agent, contact the National Flood Insurance Program (NFIP) at 1-888-379-9531 or
