Last time something like this happened, teirrasanta almost burned down, just north of Quallcomm on I-15. Wife had to hose down the back yard, and the house. Thank the stars for Ice Plant - a great natural fire boundry and ground cover.
Ice plant! If there were EVER a bit of flora that said “urban SoCal”, screw the palm trees; ice plant has it in the bag.
THAT stuff is E-V’RY-WHERE!
We had it down the back slope at the house I grew up in, over in Anaheim Hills. It’s all along the freeways, and up and down I-5 from Simi Valley south.
SoCal and ice plant are geographically synonymous.
