Bluff Erosion From El Nino (2009-2010)
Detailed Description
Bluff erosion during the 2009–10 El Niño undermined the Great Highway guardrail at Ocean Beach, San Francisco, California. The shoreline eroded, on average, 55 meters that winter, leading to lane closures on the highway and an emergency $5-million revetment along the base of this bluff.
