C) runway can be delayed until traffic increases which is expected to occur about the same time as the introduction of low-far airline service to the airport. B. Taxiways The main taxiways serving the air carrier runway, Runway 11 L-29R, include Taxiway B, Taxiway N, and Taxiway F. From a structural standpoint all of these taxiways, except that section of Taxiway B from Taxiway F to the threshold of Runway 29R, will adequately support forecast traffic for 12 to 14 years without overlay. That section of Taxiway B from Taxiway F to the threshold of Runway 29R will require a five-inch (5") asphalt overlay within three years if traffic increases. This section of taxiway was not overlaid at the same time as the remaining sections. Taxiway H is only designed for,light aircraft operations and will become an important taxiway for use of heavier aircraft once turbo jet airline services are restored. This taxiway should be reconstructed to heavy turbo jet standards. i The small portion of Taxiway D leading to the air cargo area is a new taxiway and will adequately provide a 20-year life from a strength standpoint. All of these taxiways will require maintenance slurry seal and/or overlay within 8 to 12 •' years. All other taxiways on the airport serve the lighter general aviation aircraft and have adequate section to withstand the light loads for a 20-year period, but the surface materials have weathered and within 8 to 10 years a maintenance overlay should be programmed. Taxiway D from Runway 29R threshold to the end of the Runway 29R extension should be constructed as soon as funds are available in order to provide access to the end of the _ runway extension for the cargo jet aircraft that will be operating from the Farmington Fresh air cargo ramp. The remaining portion of Taxiway D and the cross connecting ' taxiway should be constructed as additional cargo or airline operations develop on the north side of the airport. ' C. Aprons 1. Terminal Apron The terminal apron is designed to support the heavy turbo jet aircraft used by airline operations. This apron is adequate from a strength standpoint to provide service, even with.the low-fare airline operations, for 12 to 14 years after the airline operation begins. The surface of the pavement shows some sign of weathering and within six to eight years a maintenance overlay will be required. It is anticipated that before a strengthening overlay is required the terminal operations will be moved to the other side of the airport and no additional F strengthening overlays will be required. If the airline operations remain at the existing location, then within 12 to 14 years after the airline operation begins a strengthening overlay will be required. 6-2
