In an effort to ensure a more orderly evacuation of the Galveston-Houston area when a major hurricane approaches, Galveston, Brazoria and Harris counties along with the City of Houston have adopted a Zip Code Evacuation Plan (PDF) for the 2008 Hurricane Season.
Zip Code Zones
The zip code zones are labeled:
Zip Zone A
Zip Zone B
Zip Zone C
Zip Zone Coastal
Zip Zone Coastal & Zone A
The Zip Zone Coastal is the most threatened geographic area and residents of these zip codes will evacuate 1st when a hurricane approaches. Dickinson lies within Zone A and would be the 2nd area to be evacuated.
