Lifelines are the systems and facilities that provide services vital to the function of an industrialized society and important to the emergency response and recovery after a natural disaster. These systems and facilities include communication, electric power, liquid fuel, natural gas, transportation (airports, highways, ports, rail and transit), water, and wastewater.
Lifelines Restoration Performance Project
Following a disaster, the timely restoration and recovery of hospitals, homes, businesses, non-profit organizations and government of San Francisco depend on lifeline systems such as transportation, communication, water and wastewater, electricity, natural gas, and fuel. Furthermore, City efforts to improve community resilience and improve the performance of buildings following an earthquake cannot be met without the complementary performance of lifelines.
Analyzing and characterizing the resilience of interdependent infrastructure systems and the broader impact of their failure is a complex problem. The Lifelines Restoration Performance Project will develop a simple infrastructure resilience assessment framework to establish performance goals - that is, desired targets for system recovery timelines following a scenario earthquake event, and evaluate the current state of performance for specific systems in that earthquake. Understanding the gap between current and desired performance will allow us to determine what measures are needed to improve performance to meet our goals. We will accomplish this evaluation through interviews with lifeline providers and key stakeholders, use of previously performed or ongoing infrastructure system assessments and models, and workshops or exercises.
