Port of Anchorage Barge Berth Frequently Asked Questions:

Q: What can you tell me about the bench floor substrate in the dry barge berth that demonstrates confidence in quality of material below the immediate surface (e.g. no “debris” placed that could puncture/damage a barge)? 

A: Prior to construction, the natural mudflats at the dry barge berth varied from +6 MLLW at the SE corner to -6 MLLW along the western edge.  Clean gravel was imported and placed over the existing mudflats to a typical elevation of +10 MLLW, so the gravel varies from 4 to 16 feet thick with known substance.  The gravel was tested for particle size and debris contamination prior to placement, and visually inspected during placement (ICRC maintains testing and inspection records).  The floor will be routinely inspected for loose debris from barge operations, rolling boulders, tidal infill, etc. by Port personnel.  

Q: What is the horizontal offset between outside fender and dry land? 

A: The fenders slope downward at 1:12.  At the steel cap, the fenders extend out approximately 2 feet; and at elevation +10 MLLW, the fenders extend out approximately 4.25 feet. 

Q: What is vertical height difference between the bench (if maintained at design elevation) and the top of the berth? 

A: The bottom of the dry barge berth was designed and constructed at elevation +10 MLLW.  The top of the steel cap is designed at elevation +36 MLLW (26 ft difference).  There is an access ramp off the north end of the berth, so that Port personnel can maintain this height difference. 

Q: Can I perform barge roll-on/roll-off operations?

 A:  Yes, the bull rail on the south side of the dry barge berth is removable with a forklift so that a ramp can be extended from land onto the barge for roll-on/roll-off operations.  Also, the north shore of the dry barge berth is sloped so that landing craft-type barges can pull up, moor, and drive vehicles and/or equipment on and off. 

Q: Can I perform pass-pass operations?

 A:  Yes, pass-pass operations can be performed from the east and south sides of the dry barge berth.  When the wet barge berth is completed, there will be a ramp available to accommodate pass-pass operations regardless of the tide conditions. 

Q: Will there be rail access at the dry barge berth?

 A:  Yes, in the near future, one of the rail lines that now borders the east end of the Port will be extended up to dockside near both barge berths.

Q:  When can I make a reservation to use the barge berths?

A:  The dry barge berth is complete, with all fendering and moorings, and can be used now.  By the end of the 2012 construction season (Fall 2012), the temporary dock cap will be in place at the wet barge berth and it too can be used.
