The Role of GIS in Hurricane Isabel

 The assessment team was appointed by the Governor to identify the problems that occurred in responding to Isabel and to make recommendations on improvements to emergency preparedness and response.  The team, chaired by W. Robert “Bob” Herbert, former Roanoke City Manager, prepared a six page questionnaire covering disaster training and experience, preparing for Isabel, sheltering, communications, coordination, damage assessment and recovery, and public information.  The questionnaire was mailed to 128 people at the state and local level, and had a response rate of 59%.  The team also interviewed 62 individuals about their experiences trying to meet the needs of the citizens of Virginia.
 Local governments and state agencies logged thousands of hours to protect life and property and repair the damage.  Power companies worked around the clock to repair downed power lines.  In anticipation, VDOT officials had positioned personnel and equipment to the areas expected to be hardest hit before the storm got to land.  The report makes it clear that there were many things that went very well, and that government responded well on the whole.  Yet, there were some things that could have been done better.
 The report found that federal, state, and local agencies failed to communicate with each other as well as they should, and did not do a good job on the whole communicating with the public.  Communications were admittedly hampered by massive power outages. Improvements in communication and data management in the state’s emergency operation center (EOC) were among the recommendations.  
 Communication was also hampered by a lack of a way to track local government requests for assistance and to track the status of the delivery of the requested product or service.  Another of the recommendations is that data management in the EOC be improved with more sophisticated consequence management software with redundant communications and power backup.
 The GIS proved its value in many places before, during, and after Isabel.  It was, in fact used to track power outages and calls for assistance at the local government level in more than one jurisdiction.  The lessons they learned may help all of us the next time.
GIS, ISABEL, AND CHESTERFIELD
 Chesterfield County was one of two local governments that reported having used GIS in its response to Isabel.  The loss of power by 1.8 million Virginians was an extraordinary event.  People with special needs couldn’t refrigerate medicine or power medical equipment.

urricane Isabel tested Virginia’s emergency response plans in ways they had not been tested in many years.  On September 18, 2003, Isabel roared ashore affecting 99 cities, towns, and counties throughout the state.  Hardest hit was the Tidewater area where rain and wind combined with storm surges.
 In the wake of Isabel, Virginia Governor Mark R.Warner appointed the Hurricane Isabel Assessment Team to research and report on how government handled the storm and how emergency preparedness and response could be improved.  The team delivered a report in December 2003 that included a number of very specific recommendations.
 There were no specific recommendations in the report concerning the use of geographic information systems (GIS) in emergency response.  The report does cite two instances, however, where GIS was used to solve problems during and after the storm.  GIS proved to be extremely valuable in those two jurisdictions, and in many others as well.
REPORT’S RECOMMENDATIONS
 Isabel was a somewhat obliging natural disaster.  Everyone knew it was coming, and the National Weather Service had correctly predicted its course.  That allowed time for planning.  Most of the Tidewater population had left the low lying areas, some with the help of GIS.  State Police and the Virginia Department of Transportation positioned personnel and equipment early, and disaster reservists reported to Richmond.  The Governor declared a state of emergency three days before Isabel made landfall.
 Yet, Isabel generated some surprising statistics:  33 deaths; $1.6 billion in property damage; over 1,000 homes and nearly 800 businesses destroyed; 1,800,000 customers without power; and 231 boil water advisories with 50% of the population of the state without water.
