Context

Background

The CZU Lightning Complex fire was ignited by a rare dry lightning storm that struck the Santa Cruz Mountains in the early morning hours of August 16, 2020. Over the following days, the fire grew rapidly, eventually scorching nearly 80,000 acres, destroying over 900 structures, and forcing more than 70,000 people to evacuate across Santa Cruz and San Mateo counties. At the time of the lightning storm, 1,215 residents were living on the UC Santa Cruz campus, which sits in the forested hills above the city. As the fire advanced, the university coordinated with Cal FIRE and issued increasingly urgent notifications. On August 20, a voluntary evacuation was announced in the afternoon, followed by a mandatory evacuation order after 7:30 PM when Cal FIRE expanded the evacuation zone to include the campus. UCSC Police, Campus Housing, and Transportation and Parking Services (TAPS) coordinated the evacuation, providing shuttle service for residents without personal vehicles. Displaced students were relocated to San Jose State University. The Santa Cruz Beach Boardwalk opened its facilities to support UCSC operations, and Dining Services provided more than 3,000 meals per day for displaced community members. The fire ultimately stopped about a mile from the campus's northern boundary. No campus structures were damaged. The incident demonstrated the wildfire vulnerability of UCSC's unique forested mountain campus and the logistical challenges of evacuating a residential university community during a regional disaster that was simultaneously displacing tens of thousands of other residents.
