![]() Upland areas and the areas formerly known as Zone X500 is the area described above with the 0.2% chance of flooding. *There are two zones marked Zone X on the current FEMA maps. The other Zone X* areas are uplands or areas that have not been studied. Zone X* is defined as, “An area inundated by 0.2% chance flooding an area inundated by 1% annual chance of flooding with average depths of less than 1 foot or with drainage areas less than 1 square mile”. Zone AE is defined as, “An area inundated by 1% annual chance flooding (usually sheet flow on sloping terrain), for which average flood depths and velocities have been determined flood depths range from 1 to 3 feet”.
