Executive Summary

Strengthening the resilience of regions and their critical infrastructures is essential for achieving national
resilience. Over the past decade, adjacent regions and infrastructures have become more
interconnected, enabling local disasters to ripple across multiple jurisdictions and sectors, causing
disruption and damage over large geographic areas. Resilience is especially important in the lifeline
sectors—energy, communication, water, and transportation—because they underpin the most essential
functions of business, government, and communities. Much has been done to build partnerships and
improve resilience nationwide. But when disaster strikes, the biggest hit is felt by the regions and local
communities that must respond and confront the immediate consequences.
