AIRPORT DEVELOPMENT ALTERNATIVES <br />other landside alternative concepts, this concept adds a stop controlled exit from the outer curb roadway <br />due to the location of the new parallel parking and rental car road. Additionally, this concept shows the <br />location of a new cell phone lot along Northrup Drive, capable of holding 40 cars and reducing dwell <br />times on the terminal curb, thereby improving curb capacity and level of service. <br />Table 4-6 shows the approximate total area and the provided parking spaces for each functional area as <br />well as how the parking projections meet PAL 3 requirements. The space allocation in this concept shows <br />a small deficiency in short-term parking spaces but a large surplus in long-term parking spaces. This <br />concept is flexible and programmed parking areas for short-term, long-term, and rental car could easily <br />be adjusted as necessary to meet the demand as it occurs. <br />TABLE 4-6 <br />LANDSIDE ALTERNATIVE #4 PARKING SPACE PROJECTIONS <br />Projected Spaces PAL 3 Required Surplus/ <br />Land UseLand Area (SF) <br />ProvidedSpaces(Deficiency) <br />Short-term Parking100,000250282(32) <br />Long-term Parking805,0002,0131,626387 <br />Rental Car Ready-Return109,00027318489 <br />Rental Car QTA221,000553372181 <br />Total1,235,0003,0892,464625 <br />Source: RS&H Analysis, 2017 <br /> <br />4.5.3.3 Parking Garage Alternatives <br />During the landside alternatives development process, the potential for adding a parking garage to meet <br />PAL 3 demand was considered and analyzed. Ultimately, the inclusion of a parking garage in front of the <br />existing terminal building was dismissed as an unviable development option due to the preferred terminal <br />development conclusions, overall estimated constructions costs, and the uncertainty of the ability of a <br />parking garage to meet the ultimate development vision. Furthermore, the emerging technology of <br />autonomous vehicles has the potential to reduce the need for parking in the long-term. The following <br />section shows the parking garage alternatives analysis but this was ultimately dismissed from <br />consideration, included only to inform the reader of the analysis behind this conclusion and provide data <br />for an instance where circumstances have changed. <br />loop road which maintains reasonable walking distances from the farthest space to the terminal entrance. <br />Reasonable is a subjective term and it is best left to the discretion of airport administrators, but generally <br />speaking, it is recommended than any parking lots requiring a walking distance farther than ¼ mile (1,320 <br />feet) be provided a shuttle service to maintain acceptable levels of customer service. Parking any farther <br />away, as demonstrated by the existing long-term overflow lot, justifies an airport in providing a passenger <br />shuttle service, adding operational costs. One method used to maintain a premium level of customer <br />service within a confined space is the construction of a parking garage. Parking garages should be placed <br />in close proximity to the terminal building and typically command a higher price, which is necessary in <br />EUGENE AIRPORT MASTER PLAN 4-43 <br /> <br />
