The cache is not at the listed coordinates. You do not need to go there — unless you want to check out an almost-historic (since 1949) 24/7 neighborhood destination right on CA 1.
At one waypoint in CA Highway 1 Adventure: Redondo Beach – Harbor Fwy (https://adventurelab.page.link/cDbe), you are given a "Certitude Code" for this Bonus cache. Enter that code into Certitude for final coordinates, information about that destination, and a Hint.
You can validate your puzzle solution with certitude.
