This plan evaluates the risks that different hazards pose to Berkeley and engages the community in dialogue to identify the most important steps that the city and its partners should pursue to reduce these risks. The plan updates the city's plan initially adopted in 2004. To develop the 2004 Disaster Mitigation Plan, the city conducted detailed research on four major natural and two major “man-made” hazards present in Berkeley: earthquake, wildland-urban interface fire, landslide, flood, hazardous materials release, and terrorism. Since that time, new maps and data depicting the extent and possible impacts from tsunami and climate change have become available. In 2011, the city added these hazards to the list and they are incorporated into this plan..
