Am I living in a Floodplain?

Floods are a common concern in many areas of the U.S. Gulf coastal residents should be particularly aware. Floods may come in the form of flash floods, which come with little warning. Other flood conditions come on slower, as with large thunder storm fronts and tropical storms. With hurricane season not far away, it’s a good time to think about your property and the floodplains in your area.

Floodplains are broadly defined as land susceptible to flooding by any source. Areas designated as flood hazard areas are known also as “base flood” or “100-year-flood” zones. However, this can be confusing to some. A 100-year-floodplain does not mean that once your property floods, you’ll most likely see it flood again in 100 years. The calculation actually means that there is a 1% chance that flooding will occur in any year.  Floodplains are calculated by statistical estimates based on historical storm data.

Most mortgage lending agencies and banks, as well as real estate and insurance companies are well informed sources regarding floodplain information. Floodplain maps are updated periodically and are available for the public online and in print. FEMA’s National Flood Insurance Program has recently revised the digital flood insurance rate maps for many counties in Florida.

The Northwest Florida Water Management District (NWFWMD) offers a great tool for us in the Panhandle.  The NWFWMD has created a map website, known as the “Flood Information Portal”. This site is dedicated in showing the extent of areas of flood risks. The site is also helpful in determining flood insurance rates and building requirements. The site is very user friendly with a search function, where one can search for floodplain information for a specific address. A detailed report can also be generated showing both the effective and preliminary flood map for the particular address selected. The map website can be found at http://portal.nwfwmdfloodmaps.com. For further information please contact your local county extension office and county or city planning department.

Before a flood strikes, find out if buying flood insurance is right for you. If you are in an areas prone to flooding already, consider modifying your home to combat any future flooding issue. If you believe your property is at risk, please be prepared. Keep in mind that flooding in an area can lead to street closures, power outages and temporary reduction in public services.
