HURRICANE EVACUATION  PLANNING

All of the following slides are from a presentation by emergency preparedness and planning agencies for

Harris and Galveston Counties. I posted them on this website to make it easier for NE Harris County ARES Members to find them and for use during the June 15,

2008 Sunday evening TEAC and ARES Net.

RECENT PLANNING  EFFORTS

Planning  for  Hurricane  Evacuation  from  the Harris/Galveston County Coastal Areas on the Texas Gulf Coast has been ongoing for years. Since the evacuation of that area associated with Hurricane Rita, this planning has received far more attention on a much  larger scale. State, Local,  Non‐ profit  and  Private  Agencies  are  all  taking  a much  more  serious  role  in  developing  evacuation strategies and planning. Inland areas with no tradition of planning cooperation with Coastal areas have joined in the effort  as  a  result  of  lessons  learned  from  receiving  large numbers of Hurricane Katrina and Rita Evacuees.

PLAN TO STAY EVACUATED FOR A  MINUMUM OF 2 WEEKS. LONGER  EVACUATION TIMES ARE POSSIBLE  AND CONTINGENCIES FOR THAT 

EVENTUALITY SHOULD BE MADE.

TEXAS DEPARTMENT OF TRANSPORTATION HAS DEVELOPED THE FOLLOWING EVACUATION ROUTES FROM THE HOUSTON/GALVESTON AREA. THE LAST  ROUTE PLANNED FOR USE IS HWY 59 WHICH MOVES THROUGH OUR AREA.

SPONTANEOUS EVACUATION ON HWY 59 IS, HOWEVER, LIKELY.

EVACUATION PLANNING FACTSThere are an estimated  1,250,000 persons  living  in  the surge areas  in Harris and Galveston  Counties.  These  people  are  in  grave  peril  from  storm  surge associated with a category 4 or larger hurricane. Evacuation for these people is not a choice, they must leave. Evacuation Routes from these areas normally utilize 7  lanes  for outbound  traffic or can contra‐flow  14  lanes. A maximum 2000 vehicles per hour can move per lane under normal conditions at freeway speeds.  No  reasonably  accurate  models  exist  for  vehicles  per  hour  when contra‐flow  takes place.  It  is widely  accepted  that  less  than ½ this number would be possible. If we were  in a perfect world and every vehicle held 4 people, 56,000 persons an hour would mean  that  the surge zones would be clear in 22.3 hours. All evacuees would be out of Montgomery County on Hwy 59 in about 26 hrs. and to their evacuation hubs in 30 hours. This time frame would work well with  typical real world weather  forecasting and  reaction.  It does  not,  however,  consider  any  efficiency  loss  due  to  vehicle  accidents, breakdowns,  traveler  illness  or  other  unplanned  events.  Risk  of large numbers  of  evacuees  being  unable  to  pass  through  areas  borderingsurge zones is significant.
