Context: San Diego and its backcountry are subject to periodic wildfires. In October 2003, San Diego was the site of the Cedar Fire, which has been called the largest wildfire in California over the past century. The fire burned 280,000 acres (1,100 km2), killed 15 people, and destroyed more than 2,200 homes. In addition to damage caused by the fire, smoke resulted in a significant increase in emergency room visits due to asthma, respiratory problems, eye irritation, and smoke inhalation; the poor air quality caused San Diego County schools to close for a week. Wildfires four years later destroyed some areas, particularly within the communities of Rancho Bernardo, Rancho Santa Fe, and Ramona.
