Abstract : This report provides detailed information on the rebuilding of the Buhne Point marine beach, the construction fof retaining structures, and the establishment of native dune vegetation to prevent wind erosion. Appendices document physical and numerical model studies done at the Waterways Experimentation Station for the structures and beach, as well as the post-construction and post-planting monitoring programs. Buhne Point is located about 250 miles north of San Francisco, on the east shore of Humboldt Bay, California. A natural sand split was located on the western face of the point, but the area lies directly in line with wind and waves entering Humboldt Bay from the Pacific Ocean. Reports of erosion there have been recorded since the mid-19th century. By the late 1970s, erosion had become so severe that the beach had disappeared, and the shoreline had eroded back to the roadway, threatening the road and underground water, gas and sanitary sewer lines. Storm waves 10' high are common, and were sending rock flying across the road and against adjacent homes. In 1982, Congress included the area in an authorization to undertake a demonstration project to apply 'state-of-the-art methods for repairing damage to highways and preventing damage to highways resulting from shoreline erosion.' A four-year, four-phase program was implemented, and is described in this report.
