Port of Long Beach Middle Harbor Construction Monitoring

The Port of Long Beach created new berth facilities as part of their Middle Harbor Redevelopment Project. The construction required the installation of piles to support 2500 feet of new concrete wharf. MBC provided U.S. Fish & Wildlife qualified biologists to monitor potential fish mortality and the presence of marine mammals that may be harmed during construction. Monitoring included observations near the active piles being driven which would be stopped if fish mortality was observed, and marine mammal monitoring within a 100-meter safety zone for each pile drive sequence which would be stopped if a mammal was observed there.
