What is the main purpose of a floodway?
The primary purpose of the floodway is to preserve a portion of the floodplain to convey floodwaters from upstream to downstream. If the floodway is obstructed by fill or buildings, flood elevations will increase upstream of the obstruction increasing flood damages to existing properties.
How is the BFE determined?
The Base Flood Elevation is a baseline pulled together from historic weather data, local topography, and the best science available at the time.
What is an AE flood zone in Texas?
AE flood zones are areas that present a 1% annual chance of flooding and a 26% chance over the life of a 30-year mortgage, according to FEMA. These regions are clearly defined in Flood Insurance Rate Maps and are paired with detailed information about base flood elevations.
What type of foundation is best for flood zone?

What is the lowest floor for rating?
The lowest floor elevation for rating is Item C2. b, top of the next higher floor, as long as the building is not located in a V Zone (Building Diagrams 7 and 8).
What does static BFE mean?
