DESCRIPTION:
Evacuation prior to a forecasted flood event requires: established evacuation routes away from the shoreline; evacuation assembly sites; simple maps depicting evacuation zones and public outreach to educate residents about flood zones; notification and evacuation procedures to coordinate the response; and a public communication system. Evacuations are generally voluntary.



EMERGENCY PREPAREDNESS:
SHORELINE LOCATION:
Asset Specific






MEASURES COMPATIBILITY:
LIKELY IMPLEMENTING AUTHORITY:
Flood

All




CONSIDERATIONS:

ADVANTAGES:

DISADVANTAGES:





  • Low income residents may be more dependent on public transportation and therefore less capable of evacuating. Building code updates do not address neighborhood connectivity and transportation flooding.
  • Evacuating can also be difficult for elderly and disabled residents.
  • Evacuation-based policies alone do not provide flood protection to historic sites and neighborhoods.

  • Provides the flexibility to respond to low probability, but high impact flood events.

  • Evacuation is voluntary and crowded roads and transit systems can make evacuation difficult, resulting in residents being left behind.
  • Does not offer permanent flood protection benefits. Property and structures are likely to be damaged without supporting measures.




CASE STUDIES:
  • The Bay Area Regional Emergency Transportation Coordination Plan and The San Francisco Tsunami Response Plan



ENVIRONMENTAL JUSTICE CONSIDERATIONS

  • Low income residents may be more dependent on public transportation and therefore less capable of evacuating. Additionally, if they are able to leave they may not have contacts outside of their neighborhood that they could stay with and hotels may be cost prohibitive.
  • Evacuating can also be difficult for elderly and disabled residents.


HISTORIC PRESERVATION CONSIDERATIONS

  • Evacuation-based policies alone do not provide flood protection to historic sites and neighborhoods.


UTILITY AND MOBILITY CONSIDERATIONS

  • Evacuation orders can have significant impacts on mobility, resulting in significant traffic jams.


INSTALLATION AND CONSTRUCTABILITY CONSIDERATIONS

  • N/A


OPERATIONS AND MAINTENANCE CONSIDERATIONS

  • Evacuation routes, protocols, and procedures should be regularly reviewed and updated.
