What is Base Flood Elevation?
The base flood elevation is the level of floodwater expected to occur once in a hundred years. Generally, when constructing in the floodplain this is the elevation that the lowest floor of the structure, including basements and crawlspaces, must remain at least one foot above. For the technical definition as it pertains to development within the floodplain, see the Ada County Zoning Oridinance: 8-3F-4.
