FACILITY REQUIREMENTS <br />INTRODUCTION <br />Future airport facility requirements, including the type, size, and quantity, are dependent on the future <br />aviation activity levels projected in the aviation demand forecasts discussed in Chapter 2, Aviation <br />Demand Forecasts. The need for new or expanded facilities is often driven by capacity shortfalls that <br />leave an airport unable to accommodate the forecasted growth using existing facilities. However, the <br />requirements for new or improved facilities can also be driven by other circumstances, such as, updated <br />standards which have been adopted by the FAA or another regulatory agency, an evolving strategic vision <br />for the airport, the replacement of outdated or inefficient facilities that are prohibitively costly to maintain <br />or modernize, or the desire to introduce new services and facilities. These various circumstances can have <br />a significant impact on future needs and have been considered in this analysis for the airport. <br /> <br />The Eugene Airport aviation demand forecast used demographic, economic, and geographic statistical <br />analysis to derive three forecast scenarios tied to real-world factors in the Eugene area. This analysis <br />validated the FAA 2016 update to the Terminal Area Forecast (TAF). From this analysis, aviation activity <br />was forecast out for a twenty-year period (2015 – 2035). Although the forecast defines aviation activity <br />milestones for the years 2020, 2025, and 2035, it is important to understand that facility requirements are <br />driven by levels of aircraft operations and passenger enplanement demands, which may or may not <br />coincide with those specific years. Therefore, to eliminate associations between demand levels and <br />specific years, the levels of demand which trigger facility improvements, referred to as a Planning Activity <br />Level (PAL), are broken into three activity levels: PAL 1, PAL 2, and PAL 3 respectively. <br /> <br />The facility requirements analysis begins with a review of emerging industry-wide trends. Sustainable <br />development will be an overarching theme as facility requirements are considered throughout this <br />chapter. Sustainability considerations will be identified in the margin with a green leaf (shown here) for <br />easy identification. The majority of this chapter is devoted to assessments in each of the following <br />functional areas of the Eugene Airport: <br />»Meteorological Conditions <br />»Airfield Capacity <br />»Airfield Design <br />»Navigational and Visual Aids <br />»Commercial Passenger Terminal Facility <br />»Landside Facilities <br />»General Aviation Facilities <br />»Aviation Support Facilities <br />»Utilities <br /> <br />This chapter concludes with a section summarizing the key findings of the facility requirement <br />assessments which will be used to guide identification and evaluation of future development alternatives. <br /> <br />EUGENE AIRPORT MASTER PLAN 3-1 <br /> <br />
