Funding Source:

Category:

Sub Category:

Estimated Cost:

$533,600

Description:

This project will rehabilitate the runway, taxiway, and apron and apply dust palliative. The grade will be raised above the 100-year flood elevation and the runway length will be reduced to meet current FAA standards. The runway and taxiway markers and navigational aids will be repaired or replaced as needed.

Priority:

Short

Need Origination:

M&O

Justification:

Heavy maintenance is needed at this airport for safety. The operational surfaces were last improved in 1982. River ice/jam flooding occurred in May 2022. The runway and taxiways were inundated with water and most of the gravel surfacing material was washed away leaving the subbase exposed and operational surfaces with poorly compacted ruts, humps, and dips. The operational surfaces are in poor and failing condition based on the June 2022 CIMP Inspection Report. There are significant surface variations and settlement cracking the length of the runway. The crown has been graded off and subbase is now exposed. Repairs are failing, surfaces are not compacted, and there are frequent soft spots. The airport is experiencing flooding due to ice dams during the annual breakup season. The fines have been washed out of the crushed aggregate surface course due to the flooding. The runway embankment is subsiding and the southeast runway embankment is beginning to be impacted by the Kuskokwim River. Available materials for repair are insufficient to armor the embankment. NOTAMS are issued during break up and after heavy rains for soft surfaces, closing or limiting aircraft weight on the runway.
