Coastal Erosion Impacts Infrastructure and Utilities in Malibu and Carlsbad
What happened
Coastal erosion is currently being observed in both Malibu and Carlsbad, driven by climate factors including hotter ocean waters and powerful Pacific hurricanes. The erosion has been severe enough in Malibu that the ocean threatened a key road providing access to a parking lot. The L.A. County Department of Beaches and Harbors is responding to the situation by building emergency revetments along the coast. Separately, a gas main rupture has occurred in Malibu involving Southern California Gas Company.
