Abstract:

Among the facilities needed to accommodate Pier 400 at the Port of Los Angeles (POLA) was a new navigation channel to handle the increased container and liquid bulk traffic that the port would draw. The existing channel had to be expanded 5 m in length and 10 m in depth to accommodate deep-draft liquid bulk vessels. After excavation began, representatives of state and local sportfishing associations approached the port and the Corps to express concern over the impending loss of historical sportfishing grounds associated with the dredging. Additionally, the California Coastal Commission expressed a desire to mitigate the effect of the work on fish habitat. The solution was to use rocky dredged material to create a new reef that would attract many marine species and offer fishing and recreation opportunities.
