St. Mary’s Airport Improvements
Project Number: Z605630000

Current Status

The Alaska Department of Transportation & Public Facilities (Department), in cooperation with the Federal Aviation Administration (FAA), has completed a Draft Runway Safety Area (RSA) Practicability Study to identify RSA improvement alternatives for Runway 17-35. The Department will use the results of this study as the basis for the proposed action for improvements as the project moves forward. Three preliminary RSA improvement alternatives were evaluated in the study:

  • Displace Runway 17-35 Thresholds (using Declared Distances) to shorten available runway landing length but maximize take-off length.
  • Extend existing Runway 17-35 embankment 822 feet to the north and shift existing runway thresholds north to provide standard 600-foot RSA length beyond each runway end.
  • A combination of extending Runway 17-35 embankment to the north, relocating thresholds, and using declared distances.

Additional alternatives such as installing an engineered materials arrestor system (EMAS), constructing of standard RSAs beyond the existing thresholds, and others were also considered in the RSA Practicability Study.

Each alternative was analyzed for engineering practicability and financial feasibility.

A public meeting will be held in St. Mary’s to present the alternatives to the community. The Meeting is scheduled to take place on Tuesday, March 26, 2019, from 4:00 to 7:00 p.m. at St. Mary’s City Hall.
