Elevation provides the best protection for flood damage, short of relocating the house to an area that is less prone to flooding. Raising a structure does not remove it from the special flood hazard area (SFHA); therefore, it does not exempt the owner or the mortgage company from flood insurance mandates.
If you live in Louisiana, your primary objective in raising a home is likely to be flood avoidance, even if you’re not in an identified flood hazard area. Elevation is the most effective on-site method of reducing future flood damage.
