Additionally, when your BFE is high, then your policy will cost less compared to a low BFE. It’s mandatory in A and V zones, but not in X zones, which are minimal-risk areas. It’s also important to identify your BFE because it dictates the cost and kind of flood insurance you need. You can’t build living space below your BFE (nor do you want to).

If you live in a V zone (on the water), then the bottom of the lowest floor elevation must be at the BFE for your area. You can find your flood zone on FEMA’s Flood Insurance Rate Map (FIRM). These areas receive a designation because they experience the highest velocity of waves. A zones are usually near the water but not necessarily on it.
