Hardening city lifelines is always a good strategy. Powerpoint presentation courtesy of Dr Walter Hays, Global Alliance for Disaster ReductionTRANSCRIPT
STRATEGIES FOR BECOMING DISASTER RESILIENT
DURING 2013
PART 4: MAKE CRITICAL INFRASTRUCTURE
DISASTER RESILIENT
STRATEGY: “CONCENTRATE YOUR POLITICAL AND TECHNICAL RESOURCES ON ACHIEVING ONE
BIG OBJECTIVE -- SUCH AS DISASTER RESILIENT
TRANSPORTATION SYSTEMS”

WHAT HISTORY TEACHES WHAT HISTORY TEACHES
• THE FRAGILITY OF A CITY’S LIFELINES (I.E, INFRASTRUCTURE) WILL PREVENT THE CITY FROM BECOMING DISASTER RESILIENT.
• THE FRAGILITY OF A CITY’S LIFELINES (I.E, INFRASTRUCTURE) WILL PREVENT THE CITY FROM BECOMING DISASTER RESILIENT.
LOSS OF FUNCTION OF A TRANSPORTATION SYSTEM
CAN PARALYZE LOCAL, REGIONAL, AND
INTERNATIONAL EMERGENCY RESPONSE
TRANSPORTATION SYSTEMS
• Provide an essential functionessential function to society by moving people and goods from point “A” to point “B”
• Represent a substantial share of a substantial share of a country’s GDPcountry’s GDP (11% for USA.)
TRANSPORTATION SYSTEMS
• Types: Roads, railroads, mass transit, water-borne and air transport systems, and pipelines
• Scales: urban, regional, national, and international.
ELEMENTS OF TRANSPORTATION SYSTEMS
• Built infrastructureBuilt infrastructure• roads, runways,
airports, terminals, railways, stations, canals, ports, traffic control centers, maintenance and operation facilities, pipelines, etc.
• Operations sideOperations side
• vehicles, traffic safety and control, power, commun-ications and signaling, maintenance, transportation operators, etc.
FEATURES THAT AFFECT RESILIENCY
They extend over broad geographical areas
They have large numbers of components that are subject to either POINT or AREA failures.
FEATURES THAT AFFECT RESILIENCY (Continued)
Roadways and railways frequently follow river valleys (easier and cheaper to build)
Utilities, including pipelines, often follow right-of-ways (reduces legal problems and costs)
FEATURES THAT AFFECT RESILIENCY (Continued)
Multiple entities have responsibility for or oversight of the system
Typically owned by public entities and publicly funded
Usually self insured
FEATURES THAT AFFECT RESILIENCY (Continued)
Different modes of trans-portation interact with each other and other elements of the city’s built environment (hence, the name, Lifeline Systems”).
HIGHWAY SYSTEMS
Flooding from tropical storms, hurricanes, and typhoons, and tsunamis,Landslides (rock falls, spreads, slides, flows)Earthquakes (ground shaking)
