What is a 100-year floodplain?

It is the area of land inundated by flood waters from a storm that has a 1% probability of being equaled or exceeded in any given 12-month period. Some smaller watercourses in Garland are not shown on the Federal Emergency Management Agency (FEMA) published Flood Insurance Rate Maps (FIRMs), but are still subject to inundation in a 100-year flood.
