Floods are one of the most common and widespread natural disasters. Floods and flash floods can occur unexpectedly when intense storms drop heavy rains in brief periods, often with little or no warning.
Flood hazard maps, also known as Flood Insurance Rate Maps (FIRMs), are important tools in the effort to protect lives and property. The maps show the extent to which individual properties are at risk for flooding. They are created to help property owners make better financial decisions about protecting their investment.
While the FIRM maps provide a good indication of the current flood risk for a property, they may not show what the future flood risk will be due to increased development activity. The City Engineering Department uses the best available data and maps when approving new construction or substantial improvements near a floodplain. In many areas of the City, "fully developed" floodplain information is available for this purpose. Builders, developers and property owners who are purchasing property or planning construction should always check with the City of Forney Engineering Department in order to determine the location of the "ultimate" 100 year floodplain boundary.
