You are in the realm of the Coast Mountain King(L.z. multifaciata). They are in all the canyons & local mountains in Santa Barbara County. I'm not the expert of that area, but one might lay some AC(artificial cover) down in some canyons and start checking them out next spring(hint hint) or you can go hike one up along some of the many trails that traverse those canyons and keep your eyes peeled for some red, black & white looking snakes off the sides of the trails. Happy hunting
