How do you determine base flood elevation?
When you look at the FEMA maps, the BFE is the squiggly line with the number next to it. But they are often rounded to the nearest whole foot when the number goes on the map.
Can you build below BFE?
Walls of enclosed areas below the BFE must meet special requirements in coastal areas (see Fact Sheet No. 26). Setting the lowest floor at the correct elevation is critical. Failure to do so can result in a building being constructed below the BFE.
