Chapter Two FORECASTS AIRPORT MASTER PLAN The definition of demand that may be reasonably expected to occur during the useful life of an airport’s key components (e.g., runways, taxiways, terminal buildings, etc.) is an important factor in facility plan‐ ning. In airport master planning, this involves projecting aviation activity for at least a 20‐year timeframe. Aviation demand forecasting for the Grand Canyon National Park Airport (GCN or Airport) will consider commercial passenger enplanements (boardings), based aircraft, and aircraft operations. The Federal Aviation Administration (FAA) has oversight responsibility to review and approve aviation forecasts developed in conjunction with airport planning studies. In addition, aviation activity forecasts may be an important input to future benefit‐cost analyses associated with airport development, and the FAA reviews these analyses when federal funding requests are submitted. The FAA will review individual airport forecasts with the objective of comparing them to its Terminal Area Forecasts (TAF) and the National Plan of Integrated Airport Systems (NPIAS). Even though the TAF is updated annually, in the past there was almost always a disparity between the TAF and master plan‐ ning forecasts. This was primarily because the TAF forecasts did not consider local conditions or recent trends. In recent years, however, the FAA has improved its forecast model to be a demand‐driven fore‐ cast for aviation services based upon local and national economic conditions, as well as conditions within the aviation industry. DRAFT Chapter Two 2-1 The TAF projections of passenger enplanements and commercial operations at large, medium, and small hub airports are based on a bottom‐up approach. The domestic enplanements are forecast by generat‐ ing origin and destination (O&D) market demand forecasts using the Department of Transportation’s (DOT) quarterly 10 percent sample data to model passenger flow on a quarterly basis. The O&D passenger demand forecasts are based on regression analysis using fares, regional de‐ mographics, and regional economic factors as the independent variables. The O&D forecasts are then combined with DOT T‐100 segment data to generate passenger forecasts by airport pair and segment pair. The segment pair passenger forecasts are assigned to aircraft equipment in order to produce seg‐ ment pair operation forecasts. The quarterly segment pair forecasts are aggregated to produce annual airport forecasts. Forecasts of itinerant general aviation operations and local civil operations at FAA facilities are based primarily on time series analysis. Because military operations forecasts have national security implica‐ tions, the Department of Defense (DOD) provides only limited information on future aviation activity. Hence, the TAF projects military activity at its present level except when FAA has specific knowledge of a change. For instance, DOD may announce a base closing or may shift an Air Force wing from one base to another. As stated in FAA Order 5090.3C, Field Formulation of the National Plan of Integrated Airport Systems (NPIAS), forecasts should be: • Realistic; • Based on the latest available data; • Reflective of current conditions at the airport (as a baseline); • Supported by information in the study; and • Able to provide adequate justification for airport planning and development. The FAA Terminal Area Forecasts published in January 2016 were utilized to supplement the Master Plan forecasting effort. A summary of those forecasts are presented in Table 2A. The following sections of this chapter will test the reasonableness of each forecast from the TAF as well as develop updated fore‐ casts for use in this Master Plan.

Exhibit 2A summarizes the socioeconomic history and projections for Coconino County and the state of Arizona. Population estimates and projections were gathered from the U.S. Census Bureau, Population Division; and the Arizona Department of Administration – Employment and Popula‐ tion Statistics. Data for employment, income, and GRP was taken from Woods & Poole Complete Eco‐ nomic and Demographic Data Source (CEDDS), 2016. Population in Coconino County grew at a compound annual growth rate (CAGR) of 2.6 percent between 1970 and 2010. In the past five years, the CAGR has slowed to 1.0 percent. Population in the County is forecast to grow at a CAGR of 0.8 percent through 2035 to 164,844. This growth rate is behind what is projected for the entire state, which is forecast to grow at a CAGR of 1.5 percent through 2035. Employment in the County grew at a 3.6 percent CAGR between 1970 and 2010. Similar to population, that rate slowed in the past five years to 1.3 percent. Employment in the County is forecast to grow at a CAGR of 1.7 percent through 2035, which matches the projected CAGR for employment in that state. Per capita personal income (PCPI) inflation‐adjusted to 2009 dollars dipped as a result of the recession years, but has grown each of the past three years. Inflation‐adjusted PCPI is forecast to grow at a CAGR of 1.4 percent for the County and the state through 2035.

It is also adjusted for inflation to 2009 dollars. GRP for the County dipped from 2010 to 2011 as a result of the recession, but has also recovered and shown growth for the past four years.
