For buildings in hazardous areas that cannot be relocated or removed, the best option may be to retrofit them to improve their chances of surviving storm events. FEMA and other organizations have done extensive research to determine what type of construction techniques best survive storms.

Retrofitting options to improve a building's storm readiness include elevating it on open pilings above predicted flood heights, incorporating freeboard into design, anchoring structures to resist flotation, reducing or completely removing impervious ground cover, and installing protective structures over windows and doors. While not all of these options are inexpensive, there is potential funding available (see the funding page for more information).
