Sitka, AK – In November, work began on Sitka’s ANB harbor to demolish all of the existing structures and replace them with new floats and pilings including more than 60 galvanized-steel pilings, ranging from 12 to 24 inches in diameter.
In 2010, a pair of invasive tunicates – small marine invertebrates – was discovered in ANB harbor, as well as several other Sitka harbors.
As a result, the ANB Harbor project requires that all material be disposed of in a different way than usual. The material from ANB harbor will be barged down to Seattle and disposed of upland at an approved landfill or steel recycling center to prevent the invasive invertebrates from spreading to any other Alaskan ports in connection to this project.
