Municipality of Anchorage, Port of Alaska, stated the purpose is to request authorization of a 10-year maintenance dredging program required to maintain operational safety and navigational access within areas around existing Port facilities and future Port maintenance and construction projects. PROPOSED WORK: The applicant is proposing maintenance dredging and disposal to address areas of sediment accretion at all locations where the USACE dredge operations cannot access as well as allow vessels to access and dock at the existing Cargo Terminals, achieve seismic requirements, and provide construction access during the 10-year period of 2025 to 2034. Up to 125,000 cubic yards of material would be dredged from the area each year to -36 feet mean lower low water (MLLW), with a maximum depth of -40 feet MLLW. A hopper and scow would be used to transport dredged material to the USACE Anchorage Harbor Open Water Disposal Area and discharged. The cumulative total over the 10-year period could be as much as 1.25 million cubic yards.
