CHAPTER 4 ALTERNATIVE PLAN CONCEPTS Alternative 1 may introduce structures that present line-of-site issues to the ATCT, as it is expected to introduce new structures into areas currently used for aircraft taxi and require the realignment of established aircraft taxi-routes. This may require additional taxi pavement, and may complicate an already complex set of intersections of taxiways and taxilanes with the terminal ramp. Such complication could lead to aircraft congestion and pilot confusion in traveling between the runways and terminal area. This supports Alternative 2 as the preferred alternative. Alternative 2 would make use of existing Concourse B which is generally underutilized. Improvements would likely include renovation of this concourse to better accommodate passenger holding and boarding. Expansion of Concourse B would extend into the areas currently used for ground vehicle circulation. However, as ARFF operations are relocated out of this area and the passenger terminal building expands to the southwest, current ground vehicle routes are expected to be modified, so that an expanded Concourse B would not interfere with ground vehicle circulation. Alternative 2 introduces a new concourse, providing an opportunity to distribute passengers over additional area, instead of consolidating passengers in one concourse. This also provides more opportunity for additional businesses to develop and serve passengers. This supports Alternative 2 as the preferred alternative. Alternative 2 requires significant relocation of existing facilities in the North Ramp terminal area. This would likely include the old ATCT and office building, airport landscaping building, and parking for airport administration and terminal employees. The old ATCT and office building and airport landscaping building have been identified as having fulfilled their useful and economic lives and this area has been targeted for redevelopment with higher and better uses. Other improvements include the relocation of airport administration to the terminal building, making this area also available for redevelopment. Relocation of airport administration to the terminal would also likely include a new automobile parking lot for airport staff. With these North Ramp facilities and services each located to a new home, expansion of the terminal building to this area is a compatible and high-value use of this site. This supports Alternative 2 as the preferred alternative. Third Alternative A third option is to add space to the northwest, southwest, and northeast sides of the terminal to increase gates, although this option is still expected to impact existing aircraft parking, taxi-routes, and ground vehicle circulation routes. Such an option is not expected to lessen construction nor ease facility implementation, both of which would be desired of any terminal improvement. Wetland Impact No wetlands are expected to be affected by either alternative, although a wetland jurisdictional study would be required to confirm. 4-16 Eugene Airport Master Plan Update (February 2010)
