The building’s walls are designed to withstand 170-mph winds. The site also can accommodate hundreds of vehicles.

Monroe County has not ordered a mandatory evacuation of residents since 2005. Emergency managers are trying to secure space for up to 3,000 Keys residents if a major storm should threaten the islands.
