Question: 1 / 400

What does Base Flood Elevation (BFE) represent?

The highest possible flood elevation

The lowest possible water elevation during a flood

Water surface elevation from a 1% Chance Flood

Base Flood Elevation (BFE) represents the water surface elevation that will result from a 1% chance flood, also known as the 100-year flood. This means that there is a 1% chance of this flood occurring in any given year. Option A is incorrect because while it may be the highest possible flood elevation, it does not have a specific probability attached to it. Option B is incorrect because it refers to the lowest possible water elevation, which is not necessarily equivalent to BFE. Option D is also incorrect because BFE does not represent average flood depths, but rather a specific water surface elevation from a 1% chance flood.
