Revised Public Notice, POA-2003-00502-M20, Knik Arm

Expiration date: 3/21/2023

On September 6, 2022, the U.S. Army Corps of Engineers, Alaska District published a public notice for Department of the Army (DA) permit number POA-2003-00502-M20, Knik Arm for a DA permit application from the Municipality of Anchorage, Port of Alaska (Port), to remove approximately 900 feet of unstable bulkhead and fill at the north end of the Port referred to as the North Extension Stabilization Step 1 (NES1) project. This public notice has been revised to include the following two changes:  1) The existing sheet pile bulkhead would likely become unstable as the impounded soil material is removed, so the contractor has proposed installing temporary support piles along the front of the bulkhead to safely stabilize the existing sheet pile wall during material removal (see below figure). Working on one-third of the bulkhead at a time, the contractor would start by using a vibratory hammer to install 27 temporary support piles, 24-inches to 36-inches in diameter, evenly spaced along the southernmost third of the sheet pile bulkhead. With the support in place, the contractor would begin excavation and demolition at the southernmost cell using a combination of land-side and sea-side mechanical excavation. After excavating enough material to be able to safely remove the bulkhead, the contractor would remove the sheet piles and the temporary support piles with the vibratory hammer, utilizing a work barge to haul off the removed sheet piles. The contractor would then move the 27 temporary piles northward to the next one-third of the bulkhead to repeat the process. These actions would be repeated three times in total. 2) The contractor proposes to increase the potential volume of dredged material below the waterline from 1.2 million cubic yards to 1.35 million cubic yards, as a contingency in case it is necessary to dredge deeper than originally anticipated to remove or cut-off the sheet-pile below the mudline. This would increase the potential total volume of material to be disposed of in the Anchorage Harbor in-water disposal site by 150,000 cubic yards. Also, it is now estimated that the material to be removed above the waterline would approximate 115,000 cubic yards, as opposed to the 130,000 cubic yards originally estimated, for a total of approximately 1.465 million cubic yards of material to be removed in association with the project. The project site is in Knik Arm, at the Port of Alaska, within Section 7, T. 13 N., R. 3 W., Seward Meridian; USGS Quad Map Anchorage A-8; Latitude 61.233499º N., Longitude 149.985068º W.; in Anchorage, Alaska.

POA-1983-00465-M8 Thorne Bay PN

Expiration date: 3/10/2023

Mr. John Huestis, City of Thorne Bay, P.O. Box 19110, Thorne Bay, AK 99919, 907-828-3380, administrator@thornebay-ak.gov, states the purpose is to provide additional boat trailer and vehicle parking adjacent to the existing launch ramp and harbor because a planned fire station will displace some of the few parking spaces that currently exist, and the site is very underserved for parking. The applicant proposes to expand the Davidson Landing Harbor parking area by filling in a corner bounded by the boat launch ramp to the south, the existing gravel pad and access driveway to the west, harbor access/entrance to the north, and the South Davidson Inlet to the east. Approximately half of this corner area appears to have been partially filled prior to 2008, but not brought up to the surface grade of the surrounding gravel pads/access roads so it is not a useable surface. This previously filled area is lower than the high tide line, but higher than the mean high water, and much higher than the natural beach. The applicant proposes to place clean fill material from a local quarry consisting of 1494 cubic yards of shot rock, 119 cubic yards of D-1 gravel, and 411 cubic yards of armor rock as fill in 0.132-acre of waters of the U.S. to bring this corner area up to grade as a functional parking area. The surface of the proposed parking area would be approximately 74 feet at the widest point and 124 feet long at the longest point, with a 2:1 riprap slope on the east side. All work would be performed in accordance with the enclosed plan (sheets 1-5), dated July 14, 2022, and November 28, 2022. The project site is located within Section 34, T. 71 S., R. 84 E., Copper River Meridian; USGS Quad Map Cape Flattery; Latitude 55.6706º N., Longitude -132.5239º W.; in the city of Thorne Bay, Alaska.
