During the December 2009 / January 2010 storm event in the San Francisco Bay Area, significant bluff retreat occurred in several locations along Ocean Beach, causing damage to the Great Highway and to adjacent roadway facilities. There is potential for additional bluff retreat during the upcoming winter season, which may result in further damage to critical City infrastructure and could lead to significant environmental impacts to the surrounding area and to the Pacific Ocean. Therefore, the SFPUC is providing temporary protection by installing approximately 375 large-capacity sandbags along the Ocean Beach shoreline.
