All structures in hurricane prone areas, specifically the coastal counties in which at least part lie within 100 miles of the ocean in the states of Texas, Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina and Virginia, must be built to withstand winds of at least 100 MPH without sustaining any significant structural damage or shedding debris resulting from the high winds themselves.

Airports and seaports/harbors should both provide for the safety of aircraft and boats/ships from direct wind and wave damage from hurricanes with wind speeds of up to 100 mph and/or they should have a policy of flying or sailing their craft to safer places, most probably out of the path of the hurricane.
