What is a floodplain?
A floodplain is any land or area susceptible to flooding from creeks, ponds, lakes, or any other water body.
Floodplains are mapped by FEMA to show areas potentially flooded by a 100-year storm (or a 1 percent
chance of occurring every year) as well as areas flooded by a 500-year storm (or a 0.2 percent chance of
occurring every year).
