Rock-n-Road Construction has finished lining the dike that will hold contaminated dredge material from the bottom of Wrangell Narrows tidelands.
The tidelines will be turned into an expanded harbor and docking facility, said Harbormaster Jim Stromdahl. Disposal of noncontaminated material is being disposed of in Frederick Sound in accordance with the city's Army Corps of Engineers permit.
Rock-n-Road is leasing equipment owned and operated by Smart Construction of Ketchikan to complete the dredging work.
Under Phase II of the South Harbor expansion project, Rock-n-Road has until March 15, 2002, to complete dredging work on the expanded harbor basin. Dock approaches to the former Alaska Fuel float and the old Alaska Island Air floats were torn out earlier in the fall. The company also will install a platform dock and will place sheet piling along two sides of the rip rap fill area that will provide docking facilities for excursion vessels that visit Petersburg in the summer.
When filled and topped, the dike containing the dredge material will be capped and surfaced to provide parking.
The $12 million project is being constructed in five phases.
