This report provides, detailed information on the rebuilding of the Buhne Point marine beach, the construction of 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. The First Phase consisted of designing and constructing a 1,250 timber groin and a 200 long rubble-mound head to prevent sand from being transported south, downcoast. Phase II consisted of placing 600,000 cu yds of fine-to-medium grain sand to reform the almost-24 acre beach. In Phase III, a 1,050 shore-connected, rubble-mound breakwater was constructed on the northerly face of the beach, The Phase I timber groin and breakwater was given an additional 425 arched extension. Phase IV consisted of vegetating the sandfill with native plants. The vegetation program included experimental collecting and growing of 20 different native and naturalized species for a two-year period, and then extensive plantings and monitoring.
