If you and your family had to evacuate, where would you go? Part of the answer also depends on the situation, needs of the family members and type of disaster.
Shelter in place or leave? There are many factors should help determine where there is a real need to evacuate, or whether the family unit can shelter in place.
Lets take the example of a hurricane. In September of 2008 Hurricane Ike made landfall in the Galveston, Texas area. The storm surge 100 miles to the east drove 10 feet of water 20 miles inland. The only cities there were protected from the surge were the ones that had a barrier built around them.
One of the things that saved Groves, Texas from flooding was the barrier around Port Arthur. Bridge City on the other hand received several feet of water. Out of the hundreds of houses in Bridge city, only around a dozen did not receive some kind of damage from flood waters.
Even though Hurricane Ike made landfall 100 miles to the west of the Beaumont, Bridge City, Port Arthur and Orange area, if a family lived just above sea level there was a real need to evacuate.
Sometimes an evacuation means just moving to higher ground, sometimes it means leaving to area and traveling over 100 miles. But anytime a family unit leaves their house, there is the question of where are they going to go?
