Akutan Navigation Improvements
Location: Akutan, Alaska
Project Dates: 2010-2012
Owner: US Army Corps of Engineers
Contract Amount: $33,184,764
Project Details: The project provided a safe and functional harbor for the Bering Sea commercial fishing fleet and the City of Akutan. The 15-acre harbor and entrance channel construction required the excavation of roughly 825,000 cubic yards of a wet sandy material from an environmentally sensitive wetland area. This required Knik’s staff to act with due diligence during all construction operations. Approximately 27,000 tons of slope protection rock was imported via barge and placed on the harbor slopes. Armor, core, and B rock was also imported from Dutch Harbor to fortify two 700’ long breakwaters. Work for the breakwaters included an additional 150,000 cubic yards of excavation before the placing of over 105,000 tons of rock. Additional work included the installation of navigational aid markers, a drainage diversion and removal of previously identified contaminated soils.
