T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation3.5 Level 3 Screening - Airport Improvement Program (IP) AlternativesThe Level 3 Screening developed combinations of these options, identified the connected actions that would berequired for implementation, and identified a range of T.F. Green Airport Improvement Program (IP) Options.In accordance with NEPA Orders the No-Action Alternative was also developed for comparison purposes inorder to identify potential environmental impacts of the IP Options.The IP Options (described more fully in DEIS Appendix E, Alternatives Analysis) were developed in an iterativeprocess of combining Runway 16-34 Options with Runway 5-23 Options, assessing the impacts to wetlands, localroads, residential neighborhoods, and commercial development, and identifying the appropriate Airport Roadrelocation or realignment option. This analysis identified five IP Options (described in this section and evaluatedunder the Level 4 Screening process, Section 3.6). The IP Options provide a full range of alternatives that not onlymeet the Purpose and Need but also bracket the potential environmental impacts of the T.F. Green AirportImprovement Program in order to allow comparative analysis and assessment of the program elements. 102 Table 3-3presents the results of the Level 3 Screening of the IP Options that were advanced to the Level 4 Screening.Table 3-3Level 3 Screening Results: IP OptionsIPOption Runway 16-34 Runway 5-23Impacts toMain AvenueImpacts toAirport RoadImpacts toLand UsesImpacts toBuckeye BrookImpacts toWetlandsA Option 3 Option 1 Tunnels Avoids Airport Road Substantial impacts to Impacts south Substantial impacts on YesShift runway to south, Shift and extend Main Avenue Greenwood neighborhood; Avoids north Runway 34 Endfull RSAs at both ends runway to the south, and to commercial uses at Postfull RSAs at both endsand Airport Road IntersectionB Option 2A Option 2A Avoids Relocates Airport Substantial impacts to Spring Impacts north, Substantial impacts on YesShifts runway to north, Hold runway 5 End Main Avenue Road Green neighborhood Avoids south Runway 23 End,EMAS at Runway 34 threshold and extend Moderate impacts onEnd; full RSA at runway to the north, Runway 34 EndRunway 16 End full RSAs at both endsC Option 5C Option 4 Tunnels Relocates west end Substantial impacts to Avoids Moderate impacts on YesShift runway slightly Shift runway north Main Avenue of Airport Road Greenwood neighborhood, Runway 34 Endnorth, EMAS at and south, full RSAs at and commercial uses betweenRunway 16 End; full RSA both endsrailroad and Post Road inat Runway 34 EndLincoln Park areaD Option 5 Option 1 Tunnels Relocates east end Substantial impacts to Avoids Moderate impacts on YesShift runway slightly Shift and extend Main Avenue of Airport Road Greenwood neighborhood; and Runway 23 Endnorth, full RSAs at runway to the south, limited area of commercial usesboth ends full RSAs at both ends between railroad and PostRoadE Option 3B Option 4A Tunnels Relocates east end Substantial impacts to Avoids Moderate impacts on YesShift runway to south,EMAS at both endsShift runway northand south, EMAS atboth endsMain Avenue of Airport Road Greenwood neighborhood; andresidences to Bellevue Ave tonorthRunway 23 End,Moderate impacts onRunway 34 EndNo- Existing Existing No No Includes Completed and No No YesActionCurrent Part 150 VLAPCarriedForward102 Some Level 2 Preliminary Alternatives, such as Runway 16-34 Option 2B, were found to be reasonable and feasible and would meet the purpose and need,but were not included in the IP Options because they did not provide the best fit or had similar impacts and/or benefits to other Preliminary Alternatives thatwere advanced to Level 3.Chapter 3 – Alternatives Analysis 3-14 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH03_Alternatives_JUL_2011.doc
