Green Airport.2 Forecast includes 2010 FEIS No-Action Alternative Forecast and Incremental Build Alternative Forecast. The extension to Runway 5-23 for Alternative B4 would be implemented by 2015. Alternative B2, including extending Runway 5-23, would be implemented by 2020. The facility requirements analysis provided in thischapter only considers the 2015 implementation of the Build Alternatives (see Table 2-2).3 Includes range from 2010 FEIS No-Action Forecast to FEIS Build Forecast in the future years.4 There are currently 22 gates at the terminal.Annual Departures per Gate MethodThis method applies the ratio of annual departures per gate for the existing EIS year (1,841 annual air carrier andcommuter aircraft departures per gate based on 2004) to the EIS future study years, and assumes that the currentusage and utilization of the gates will remain constant over the EIS study timeframe. Table 2-6 shows the results ofthe analysis of the annual departures per gate method using the 2010 FEIS Forecast. The analysis using this methodshows that additional gates may not be required during the EIS study years.Table 2-6Annual Departures per Gate Method – 2010 FEIS No-Action Alternative and Build AlternativeForecasts2010 FEIS No-Action FEIS Build Forecast AirForecast Air Carrier and Carrier and CommuterCommuter Airline Airline Departures 2 Estimated GateYear Departures 1 Operations per Gate Requirement 32004 40,496 n/a 1,841 22 22015 32,659 37,039 1,841 18-202020 34,708 39,100 1,841 19-212025 36,921 41,301 1,841 20-22n/a = not applicable; 2004 represents existing conditions prior to the implementation of any potential Build Alternative.Sources: Vanasse Hangen Brustlin (2010).1 Forecast based on existing infrastructure and facilities at T.F.
