Mr. Stephen Ribuffo's (Port of Anchorage) stated purpose is to construct the South Backlands Stabilization project in order to stabilize the shoreline constructed under Department of the Army (DA) permit POA-2003-502-N, Ship Creek, and protect the Alaska Basic Industries, Inc. (ABI) cement storage dome at the Port of Anchorage. The project site is located within Section 7, T. 13 N., R. 3 W., Seward Meridian; USGS Quad Map Anchorage A-8; Latitude 61.233588º N., Longitude 149.894339º W.; in Anchorage, Alaska. PROPOSED WORK: The Municipality of Anchorage through its Port of Anchorage Department (POA) proposes to construct the South Backlands Stabilization (SBS) project to stabilize the shoreline constructed under DA permit POA-2003-502-N. The SBS project would consist of grading approximately 7,500 square yards of shoreline to a three to one slope (3:1, horizontal:vertical) between the current surface elevations of +34 feet mean lower low water (MLLW) and +20 feet MLLW, lining the graded slope with geotextile fabric, placing 2 layers of underlayer armor rock (approximately 12,100 cubic yards (CY)) on top of the geotextile fabric, placing 2 layers of primary armor rock (approximately 24,100 CY) on top of the filter rock, and placing approximately 18,500 CY of type II classified fill on the landward side of the armor rock to tie into the existing shoreline. The SBS project as a whole would discharge approximately 54,700 CY of fill material into 4.6 acres of waters of the U.S. Approximately 24,900 cubic yards of material would be excavated from below the mean high water mark to prepare the site for the placement of fill material. Please see South Backlands Stabilization Project Description (Appendix A) for additional information.
