Since about 2004, subsidence and the emergence of medium fault scarps have occurred along Riverbed Street to the water, indicating the failure of the toe of the slope (likely due to failure of 1950s-era bulkheads) and increased water in the soil. There is evidence that a failure plane exists about 100 feet (30 m) behind the surface of the hillside.
A bulkhead is a retaining wall, such as a bulkhead within a ship or a watershed retaining wall. It may also be used in mines to contain flooding. Coastal bulkheads are most often referred to as seawalls, bulkheading, or riprap revetments. These manmade structures are constructed along shorelines with the purpose of controlling beach erosion.
Bulkhead gates are vertical walls with movable, or re-movable, sections. Movable sections can be lifted to allow water to pass underneath (as in a sluice gate ) and over the top of the structure. Historically, these gates used stacked timbers known as stoplogs or wooden panels known as flashboards to set the dam's crest height.
