Alaska Department of Transportation and Public Facilities (DOT&PF) states the purpose is the runway, taxiway, safety area, and apron are in poor condition due to erosion and settlement; the runway safety areas are not large enough to meet federal standards for the size of aircraft currently using the airport; and more apron space is needed for safe operations and provide additional space for a new Snow Removal Equipment Building. The purpose for this is to improve safety, lower maintenance costs, provide more additional storage for snow removal equipment, and extend the service life of the import. All work would be performed in accordance with the enclosed plan (sheets 1-6), dated October 5, 2021. The work includes the excavating 12,000 cubic yards (cy) of native material and placing approximately 48,000 cy of fill in palustrine emergent wetland to expand the runway and the apron (Figures 2-3). The 48,000 cy of fill material to be placed includes 14,200 cy of native soil, as well as 120 cy of rip rap, and 33,600 cy of imported clean sub-base and porous backfill. Imported clean fill and rip rap will be obtained from established material sites in Western Alaska, transported by barge to Kongiganak, transported by truck from the barge landing on the Kongnignanohk River along the established gravel access road to the Kongiganak Airport, and placed in the project area. The project is expected to be completed over two construction seasons. The project site is located within Section 28, 32, 33, T. 2 S., R. 79 W., Seward Meridian; USGS Quad Map Kuskokwim Bay D-3; Latitude 59.961991º N., Longitude 162.880371º W.; in Kongiganak, Alaska.
