ALBANY BEACH SHORELINE STABILIZATION AND BEACH/DUNE NOURISHMENT

摘要

The Albany Beach Restoration Project was initiated with the goal of stopping landfill erosion into San Francisco Bay, while creating aquatic habitat, and nourishing a pocket beach at McLaughlin Eastshore State Park, Albany, California. The site contains an existing sandy pocket beach which is unique to San Francisco Bay, and was formed by construction of the Albany Neck and Bulb, which was created as a landfill. Coastal engineering analysis, numerical modeling of coastal processes, and pocket beach morphology modeling were performed to evaluate and protect against erosion on the Albany Neck and prevent contaminant entry to the Bay, evaluate potential enhancement alternatives for the sandy pocket beach, and develop design criteria for living shorelines structures/habitat elements. In addition, analysis was performed to evaluate the stability of living shoreline structures, including a crescent reef with oyster shell nourishment, a pebble beach and groin system, avian roosting islands/breakwater elements, and tidepools.
