POA-1922-00022-M26

Posted: 11/26/2018

Expiration date: 12/26/2018


Mr. Karl Amylon with the City of Ketchikan, states that the project purpose is to improve navigational safety and access while allowing for more efficient berthing for cruise ships moving to and from Berths I and II by removing the rock pinnacle to a target depth of -42 feet Mean Lower Low Water (MLLW). Work being proposed is to remove up to 15 vertical feet of rock (7,500 cubic yards) from a 0.76-acre area.  This rock pinnacle removal would bring the ocean bottom depth to -42 feet MLLW.  There would be up to 50 days of blasting (25 to 50 blasts anticipated), with up to one blast per day at a maximum weight of explosive up to 75 pounds per blast.  The proposed project would occur between September 16, 2019, and April 30, 2020, with blasting occurring between November 15, 2019, and March 15, 2020.  The blasted rock material would be removed using a mechanical dredging technique (i.e., clamshell dredge, excavator from a barge, etc.), placed on a barge, and moved to an appropriate stockpile or placement site, permitted as necessary. The project site is located within Section 30, T. 75 S., R. 91 E., Copper River Meridian; Latitude 55.3392º N., Longitude 131.6494º W.; in Ketchikan, Alaska. Please contact Ms. Roberta Budnik at (907) 753-2785, toll free from within Alaska at (800) 478-2712, by fax at (907) 753 5567, or by email at roberta.k.budnik@usace.army.mil if further information is desired concerning this notice.
