6 William Dolan Deputy Airport Director Airfield Paine Field th St S.W. Ste A Everett, WA March 9, 2009 Re: Parking analysis information request Dear Mr. Dolan Thank you for your letter of March 2. We are pleased to respond to the questions in your letter regarding the number of passengers associated with a representative schedule by Allegiant Air at Paine Field (PAE). The following table shows: Passenger per aircraft (based on 90% load factor for a 150 seat MD 80) Passengers per car (based on differing point of origin estimates for four different destinations from PAE) Estimate of overnight parking demand Year 1 Year 3 Year 5 Departures/week Destinations Passengers per departure PAE point of origin (percent of pax) 90% 72% 71% PAE point of origin passengers/wk For PAE point of origin passengers Pax/car Night's stay in destination Cars/wk Car nights/week , Car nights/day The answers to your other questions are as follows: A - 5

7 Number of personnel on site at any one time: around six. This should not change significantly even as the number of flights increase, as we would not expect to handle more than one flight at PAE at a time. Note, these staff may be contracted rather than directly employed by Allegiant. Expected time of arrival of passengers at the terminal prior to aircraft departure: ranges from a half hour to two hours, with an average of over an hour. Typical time for passengers at terminal after landing before drive away: between 15 and 45 minutes. We do not have any parking studies of other airports. It is hard to think of an exact parallel for PAE within our existing system but we would encourage you to discuss this matter with Dave Gordon at Ft Collins/Loveland Airport in Colorado (where we serve only Las Vegas it s worth noting that local point of origin for Las Vegas is much higher than for our other destinations this is why the PAE percentage point of origin declines with time in the table above). You are obviously most welcome to discuss this with other airports in our system as well. Please let us know if you have any further requests. Best regards, Robert Ashcroft VP Planning A - 6

8 MEMORANDUM April 18, 2009 To: From: Re: Bill Dolan - Snohomish County Airport Ryk Dunkelberg, Mark McFarland - Barnard Dunkelberg Joel Hirsh Estimates of Traffic Impacts and Terminal Capacity - Revised As requested, Hirsh Associates (HA) has evaluated the forecast schedules and passengers provided by Horizon and Allegiant for new service to Paine Field (PAE). HA has developed automobile traffic estimates based on this and other assumptions, as well as estimates of terminal capacity which may be used in the environmental assessment for the airport. Airline forecasts and data for 1, 3 and 5 year planning periods were based on the following letters to William Dolan: Horizon Air - March 16, 2009 Allegiant Airlines - March 9, 2009 and follow up phone calls HA also spoke with the Airport s traffic consultant, Edward Koltonowski, on April 9 to discuss assumptions and impacts for the vehicular traffic analysis. Table 1 (attached) summarizes the airline data, assumptions made by HA, and calculations of the various forecasts. A. Airline-Furnished Forecasts Horizon has forecast initial service at 6 departures per day, increasing to 10 per day after 5 years. All flights would use 76 seats Q400 aircraft which is the main aircraft in Horizon s fleet. On an average basis, Horizon is forecasting a local boarding load factor of 61-63%. This is less than Horizon s typical system-wide load factor of approximately 73-74%. Allegiant provided forecasts on a weekly basis beginning at 2 departures/week, increasing to 10 weekly departures after five years. All flights would use 150 seat aircraft, although Allegiant does have some smaller aircraft. On an average basis, Allegiant is forecasting a load factor of 90% in all years. Allegiant s system-wide load factor has grown from 81% in 2006 to almost 90% in On an annual basis, Horizon s average daily boardings were multiplied by 350 days. This takes into account adjustments for flight cancellations and typically reduced schedules on weekends. Allegiant s weekly boardings were assumed to have a full 52 week s activity. This results in an annual enplanement forecast of 112,000 in Year 1 growing to 238,200 by Year 5. A - 7

9 B. Peak Hour Forecasts Terminal facilities are typically sized for a peak hour of an average day during the peak month (design hour). The peak hour reflects a rolling 60 minute period and may not correspond to a clock hour (i.e. 7:00-7:59). This design hour may be modified to reflect a weekday (in the case of a predominantly business market) or a specific day of the week (in the case of a seasonal leisure destination). Where there is no existing service (or a major change in service is anticipated), the design hour should reflect the anticipated air service at realistic maximum load factors. For PAE, it is likely that both airlines would have flights during the peak hour, and the terminal has been sized for this assumption Although the airlines have projected average boarding load factors in the range of 61-90%, during a peak hour it is reasonable to assume a 90% load factor for both carriers given industry trends. The peak hour is based on the gate/terminal capacity and it is anticipated that no additional gates would be provided within the 5 year planning period. Thus the peak hour would be unchanged at 205 enplaned or deplaned passengers. C. Likely Peak Hour Traffic Impacts It is understood that peak hour traffic estimates are needed for the environmental analysis. As noted above, the peak hour activity at PAE would likely consist of one arrival and departure by each airline. Ground time for these airlines is typically minutes, so the gates would turn within an hour. Exact schedules are not known at this time (and would also likely change many times over the forecast period), but it is reasonable to assume that while the flights would occur within an hour, they would not be simultaneous departures or arrivals. Departing (enplaning) domestic passengers typically arrive at the terminal following a distribution which ranges from as early as 2 hours to as little as 30 minutes before scheduled time of departure (STD). Leisure passengers with checked baggage tend to arrive earlier, while business passengers with no checked baggage tend to arrive closer to STD. For the purpose of estimating maximum traffic impacts, it is reasonable to assume that all passengers arrive at the terminal within a 60 minute period, and that passengers from both flights would arrive during that same 60 minute period. Arriving (deplaning) passengers will leave the terminal as soon as they can claim their bags, arrange for ground transportation, and/or pay for parking. This will typically occur within minutes of arrival time. Thus, it is also reasonable to assume that both flights passengers would leave the terminal within a 60 minute period. The enplaning and deplaning ground traffic would occur in separate hours, but possibly as sequential time periods. It is not known at this time, at what time of day these peaks would occur, and thus the direct impact on existing traffic volumes. Peak hour passengers are typically converted to vehicle trips based on average vehicle occupancies (passengers/car). At an airport like PAE with adequate parking, it is anticipated that passengers would either park at the airport (originating passengers) or use a rental car (destination passengers). Thus, each traveling party would generate one vehicle trip when departing and one when arriving. Very few passengers would be expected to be picked up or dropped off by others which would generate two trips per traveling party. 2 A - 8

10 Allegiant estimates that the vehicle occupancy would initially be 2.0 passengers/car, increasing to 2.4. This is based on their internal data on traveling party size for different markets which are anticipated to be served from PAE. Horizon estimated an occupancy ratio of 2.5, but HA believes this is high given the primarily business markets anticipated to be served. A more conservative occupancy ratio of 1.5 passengers/car is recommended to be used for traffic analysis. This results in estimated peak hour directional trips of 114 in Year 2, decreasing to 102 directional trips in Years 3 and 5. The reason for the decrease in trip generation is due to the increased vehicle occupancy ratio for Allegiant. D. Typical Daily Traffic Impacts It is also understood that daily traffic volumes are needed. For PAE, an average day must consider both Horizon fights which are scheduled on a daily basis and days when Allegiant operates. For Horizon, the airline s estimate of average daily originating passengers provides a reasonable basis for typical day directional traffic. This was divided by the 1.5 passenger/car ratio used for peak hour traffic estimates. For Allegiant, in Year 1 there would only be activity on 2 days per week. In Year 3, the 6 weekly trips would also not likely result in more than 1 flight per day. In Year 5, the 10 weekly trips would mean that most days would have a second flight. In each of the planning years. The airline s estimate of average originating passengers per flight in each year was used and divided by the passenger/car ratio to estimate daily directional trips. This results in 255 to 433 directional vehicle trips for a typical day in Years 1 and 5 respectively. E. Terminal Capacity Estimates As noted in Section B, terminal facilities are sized to accommodate a design hour level of activity. Most people, however, want to know the capacity of a terminal, typically in terms of annual passengers. The conversion from design hour volumes to annual passengers requires a number of assumptions including the number of times gates are used during an average day; and load factors (annual and/or peak hour). Two approaches are outlined in Table 1. Maximum Capacity - This is based on the capacity of the terminal s gates and a range of departures per gate. For PAE, the gates have a design capacity of one 75 seat regional aircraft plus one 150 seat mainline aircraft for a total of 225 seats. A typical spoke (non-hubbing) airport will average 4-6 departures per gate per day. So PAE could have a daily capacity of 900-1,350 departing seats per day if both gates were used for the largest aircraft they are sized for. A high average daily load factor would be for PAE to generate originating passengers at the airlines system-wide load factors. An average of Horizon and Allegiant s system load factors is approximately 81%. Thus, a load factor range of 80-85% would be very generous. No airport operates at the same level of activity every day of the year. As noted in Section A, 350 day year is typically used to account for cancelled flights and reduced weekend schedules. This results in a capacity of approximately 720-1,150 daily enplanements, and an annual capacity range of 252,000 to 401,600 enplanements. 3 A - 9

11 Daily directional trips would be based on an average of the Horizon and Allegiant long term vehicle occupancy factors since equal operations are assumed. This would result in approximately daily directional trips based on an average occupancy of 2.0 passengers/car. Realistic Capacity - A more realistic capacity considers the mix of aircraft which might actually serve the airport. For PAE, a combination of 10 daily regional departures and 2 mainline departures would be realistic giving a total of 6 departures per gate, and reflecting the proposed airlines anticipated service. This results in 1,050 daily departing seats. For an average load factor, a weighted average of the system-wide load factors was used for the 12 departures. This is approximately 76%. As before, a range using this as a base (75-80%) would provide a generous estimate of approximately daily enplanements. Applying the 350 day annualization factor results in an annual capacity of 275, ,000 enplanements. Daily directional trips would be based on a weighted average of the Horizon and Allegiant long term vehicle occupancy factors since most operations are assumed to be by Horizon. This would result in approximately daily directional trips based on an average occupancy of 1.7 passengers/car. 4 A - 10
