Purpose & Need
• The Airport's Airport Reference Code (ARC), 6 -II, determines the
runway to taxiway separation distance. The FAA requires a runway
to taxiway separation of 240 ft. for ARC 6 -II aircraft.
• The current separation between Runway 7 -25 and parallel Taxiway
A is 200 ft.
• Future AIP funding is contingent on meeting FAA standards.
• A study conducted in 2016 determined that the preferred
alternative to meet FAA standards is to shift runway 40 ft. to the
northwest of its current location. An Environmental Assessment to
determine the impacts of this project commenced in March 2017.
