T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationIn 2020, under Alternative B4, two non-residential noise-sensitive sites, the Jehovah’s Witnesses of Warwick(Site PW017) and Baha’i Faith (Site PW039), would be newly exposed to noise levels that would make themeligible for sound insulation; however, Baha’i Faith has been sound insulated as part of a previous soundinsulation effort under the Part 150 NCP. In 2025, the same two sites as 2020 and an additional site, the JohnWickes School, would result in a significant noise increase all of which would be eligible for sound insulationmitigation. The John Wickes School has also already been sound insulated as part of a previous soundinsulation effort under the Part 150 NCP. Figure 5-9 shows the location of non-residential noise-sensitivelocations within the 2025 DNL 60 dB contour of all of the Alternatives.Aircraft Ground Noise (Integrated Cargo Facility Operations) – 2020 and 2025The cargo noise analysis results indicate there would be no off-Airport noise impact due to cargo noise. Refer toAppendix F.2, Aircraft Ground Noise (Cargo) Analysis, for the complete analysis.Vehicular Traffic Noise Impacts – 2020 and 2025Under Alternative B4, the off-Airport roadway improvements of Partially Relocated Airport Road andRealigned Main Avenue would be complete by the end of 2015. Overall, the same number of housing unitswould be impacted by vehicular traffic noise in 2020 when compared to the No-Action Alternative. In 2025,vehicular traffic DNLs are expected to increase by less than one dB over 2020 levels due to projected growth inarea vehicular traffic volumes. Tables 5-26 and 5-27 summarize the computed exterior traffic noise levels in eachof the neighborhoods that would be affected by traffic noise due to the proposed roadway improvements(Realigned Main Avenue) for Alternative B4 in 2020 and 2025, respectively.Table 5-26Alternative B4: 2020 Summary of Traffic Noise Impacts by NeighborhoodTotal Number of Housing Units 1Loudest-hour Leq in dBAExposed to Noise ImpactChangeRelative toBaseline No-Action Alt.

For the Alternative B4 case, the number of impactedhousing units is due to both traffic noise levels that approach or exceed the relevant FHWA NAC and that cause a substantial increase over baseline levels.3 See Figure A.4-23 in DEIS Noise Supporting Attachment A.11, Supporting Report Graphics.4 See Figure A.4-24 in DEIS Noise Supporting Attachment A.11, Supporting Report Graphics.5 See Figure A.4-22 in DEIS Noise Supporting Attachment A.11, Supporting Report Graphics.Chapter 5 - Environmental Consequences 5-36 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
