| | Miami Harbor Dredge Works
The project entails removal of approximately 1.12 million yd³ of material from Fisherman Channel through the Lummus Turning Basin, to create a depth of 42 feet. The material is to be placed at the Ocean Dredged Material Disposal Sites. Additional work is apportioned in five options:
-
Maintenance dredging of ~210,000 yd³ of shoal material from Cut 3 through the Main Turning Basin to 42-foot depth.
-
Construction dredging of ~194,000 yd³ of material from the berthing area adjacent to Fisherman Channel and Lummus Turning Basin to 42 feet.
-
Construction dredging of ~5,000 yd³ of material from the Dodge Island Cut berthing area to 34-foot depth.
-
Maintenance dredging of ~22,000 yd³ from Cuts 1 and 2.
-
Maintenance dredging of ~43,000 yd³ from port berths adjacent to the main ship channel and Fisherman’s Channel.
A variety of equipment will be employed in the project, including cutter suction, trailing suction hopper, and bucket dredges, drillboat(s), spider barge loaders, and material barges, as well as workboats, tugs, and numerous pieces of support plant.
Environmental requirements are rigorous and numerous. As the construction dredging works include drilling and blasting and several endangered species inhabit the area, the work requires observers for endangered species protection (hopper dredging only) turbidity monitoring, vibration monitoring and control activities, and dolphin/manatee watch activities. The maintenance work also requires turbidity monitoring and species protection measures. |
