IMPLEMENTATION AND FINANCING PLAN 8. Taxiway A1-A5: Phase II - Construction This airfield project is a modified version of an existing 2010 Master Plan CIP project and is a critical step forward for improving airfield safety and efficiency. Key improvements to the airfield include routine rehabilitation of Taxiway A, A1, and A2, geometry corrections to meet FAA design standards for ADG III/TDG 5 aircraft, and the addition of paved shoulders which are appropriate for taxi routes used by commercial operations with narrowbody jets. Additionally, another segment of SMGCS lighting preparations are installed for the future completion of a full SMGCS route along Taxiway A. The relocation of Taxiway A3 provides an FAA recommended 90 degree runway connector suitable for handling the existing and forecast airfield capacity needs within the planning period. The selected location of the new Taxiway A3 is optimally located for the fleet mix (existing and forecast) at Eugene Airport. Runway Exit Design Interactive Model (REDIM) modeling was performed to determine optimal taxiway exit locations for Runway 16R-34L as a whole. Modeling conclusions determined the location of Taxiway Connector 1 (A3 replacement) will capture 31% of all aircraft operating in both landing directions, primarily capturing small general aviation aircraft landing on Runway 16R and large commercial aircraft landing on Runway 34L. The location of the new taxiway connector also allows efficient access for general aviation aircraft to planned future consolidated facilities as well as efficient access to commercial aircraft requiring access to existing (and planned future) terminal facilities. One enabling study for this project is a Drainage Report evaluating the existing storm drain network of Drainage Basin A. The report will need to identify relevant drainage elements such as topography, drainage basins, flow patterns, pipes, structures, outfalls, and soil types. Survey should be performed to identify precise locations of all storm water elements with associated CAD drawings to aid in future project design. The report should identify regulatory requirements and coordinate with other relevant local stormwater management plans. Funding for this airfield project is programmed into the FAA Accepted 5-Year CIP from federal AIP entitlement funds, discretionary funds, and the required local match. The remaining amount is programmed to be covered by airport revenue funds or is defined as an unmet need. 9. Environmental Assessment - Runway 34R Wetland Fill for Wildlife Hazard This . Funding for this study is programmed into the FAA Accepted 5-Year CIP for federal AIP entitlement money and the required local match. 10. Reconstruct Terminal Taxiways: Phase I Design and Environmental Prior to the construction of terminal area taxiways and RON parking pads, federal regulations require the assessment of potential environmental effects from proposed actions that may affect environmental resources. A complete evaluation of the resource categories identified in FAA Orders 1050.1F and 5050.4B is required. Potential environmental impacts associated with the projects in this EA can be found in Chapter 7, Environmental Overview.
