All the big campuses here like JPL and the Getty are built for this (it’s more or less standard now for insuring anything high value). They have landscaping designed to slow down fires, dedicated water systems, and firebreaks all around the buildings. The civilian evacuation order is because the area south of the fire is densely built up with single family homes without much in the way of defenses and JPL has to comply with that.
Thankfully the wind has died down significantly from last night, so we’re in a better shape, but there are still high wind warnings till 6pm and the fires are 0% contained.
