A forward looking (part of a) solution for Malibu would be the county acquiring and maintaining beach paths every few houses. Prescribed 10' wide fire breaks.
This solves the fire problem AND the limited access to a public resource that is common in Malibu.
Ideally a permeable surface without any growth, cleared at least 2x a year.
especially for this fire, jumping doesnt mean that everything 2 miles down wind also burned down. buildings that far had the opportunity to burn, and if they dud, had the opportunity to burn their neighbors, and another 2 miles down.
i imagine ember density is more interesting than distance?
That would not have solved the problem in this fire since wind speed was so high. The videos showed embers traveling far and fast. Having a 10 foot fire break would not have prevented the spread. One thing to look into is how the fire started and if the electrical equipment can be made safer, like being underground in some places.
