Identify before the storm: this map highlights documented landslide areas, drainage corridors and major access roads. It deliberately does not label an entire street “dangerous” unless an official source supports that conclusion.
Historic landslide reference points
Santiago Landslide — Serrano Ave. / Avenida de Santiago
Anaheim reports that intense El Niño rains accelerated movement of the roughly 25-acre Santiago Landslide. Evacuations, residential damage and emergency stabilization followed; the area is now managed through the Santiago GHAD dewatering system.
City of Anaheim: Santiago GHAD ↗Ramsgate Drive Landslide
Anaheim's hazard plan records a slope failure after an extended rain event that destroyed three homes and a private street. The marker on the map is a historic reference point, not a current warning.
