Ocean Beach Storm Damage Reduction Feasibility Study City and County of SanFrancisco, CA. Final Feasibility Study

摘要

The report presents information developed in the course of a multi-yearinvestigation of the need for shore protection and storm damage reduction. The study area was 8.6 miles of the Pacific coast, known as Ocean Beach, in the City of San Francisco, CA. The study area extended from Cliff House to Fort Funston. The beach portion of the study area is in the Golden Gate National Recreation Area, under the jurisdiction of the National Park Service. Facilities threatened with damage included the Great Highway, parking lots of the GGNRA, a buried storm and sewer water transport box, a sewer pumping plant and ultimately houses and businesses. The report records the Ocean Engineering, Economic, and Geotechnical studies used to formulate and analyze a variety of alternative measures, including structural seawalls and revetments, as well as beach and dune nourishment. The final analysis indicated that most of the study area, while not absolutely safe, had a low probability of erosion.
