SAN FRANCISCO, CA—The Department of Public Works (DPW) temporarily realigned lanes of the southbound Great Highway south of Sloat Boulevard near Lake Merced Boulevard to allow city and federal crews to continue stabilizing a coastal bluff there. Regular seasonal storm activity has caused anticipated erosion and the agencies took action to ensure public safety, protect the roadway and to maintain access to Ocean Beach.

DPW realigned one southbound lane of the Great Highway to keep traffic flowing and are investigating ways to have two southbound lanes open using a detour side road created 2003 for this purpose. DPW and the National Park Service (NPS) are continuing to address the erosion just south of Sloat Boulevard, along a 650-foot stretch of coastal bluff between the south parking lot and Fort Funston that has been problematic since the 1999 El Nino storms.

In 1999, to protect nearby infrastructure, the Board of Supervisors authorized the Department to annually maintain the shoreline by replenishing the sand that washed away. Work over the next several months will include evaluating expanding the area of replenishment and exploring bluff and roadway stabilization with the Golden Gate National Recreation Area. 

DPW is working with the NPS and the Army Corp of Engineers (COE) on a long-range plan to  appropriately respond to the continuing beach erosion impacts at Ocean Beach. The COE and DPW are acting on shoreline stabilization studies and technical reports that have been produced over the last several years to stabilize the beach and protect the road. The City, NPS and the COE are evaluating using sand from several nearby sources, including Ocean Beach and the San Francisco Ship Channel, to provide protection from large winter storms.
