With a population, geography, infrastructure, and economy comparable to those of states and nations, Los Angeles is one of the most complex megacities of the world. City limits cover 469 square miles, but greater Los Angeles is 10 times that size -- a region of individual neighborhoods that comprise many different languages, cultures, and ethnicities. The city’s central question is how a city of L.A.’s size and scope can truly be sustainable and resilient in a changing and increasingly globalized world, particularly in the face of water shortages and seismic challenges.

Resilience Challenges

  • Aging Infrastructure
  • Drought
  • Earthquake
  • Tsunami
  • Wildfires
