T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationLand Use Compatibility – 2020 and 2025Figure 5-22 shows the land uses that would be exposed to the DNL 65 dB and above noise levels in 2020 and 2025 forAlternative B4 compared to the No-Action Alternative. The residential areas that would be exposed to DNL 65 dBand above under Alternative B4 in 2020 and 2025 are presented in Table 5-45.Table 5-45Alternative B4: Residential Land Exposed to DNL 65 dB Compared tothe No-Action Alternative (2020, 2025)AlternativeNo-Action AlternativeAlternative B4Alternative B4 Change from No-Action AlternativePercent ChangeParcels1,1031,156+53+5%2020 2025AcresParcels1871,4382051,389+18-49+10%-3%Acres256244-12-5%Sources: RIGIS; Field verification by VHB, Inc., 2005; City of Warwick Assessor’s Parcel Data.Notes: All land uses fall within the City of Warwick. The residential land uses that would be exposed to DNL 65 dB and above were determined after first excluding thenon-project-related residential land acquisitions that would be acquired under the Completed and Current Part 150 VLAPs, and project-related mandatoryresidential land acquisitions (for construction, noise mitigation, and RPZ clearing).Under Alternative B4 in 2020, the amount of residential land exposed to DNL 65 dB and above would increaseby 53 parcels totaling approximately 18 acres (representing a five percent increase in land area) in the amount ofresidential land area that would be incompatible compared to the No-Action Alternative. One non-residentialnoise-sensitive site, Baha’i Faith (PW039), would be exposed to noise levels that would make the site eligible forsound insulation (DNL 65 dB and above when compared to the No-Action Alternative) in 2020 underAlternative B4; however, this site has already been sound insulated as part of a previous sound insulation effortunder the Part 150 NCP (Table 5-10).In 2025, the amount of incompatible residential land would be reduced by 49 parcels totaling 12 acres(representing a five percent decrease in land area) under Alternative B4 compared to the No-Action Alternative.This decrease is due to mandatory residential land acquisitions for construction, noise mitigation under theFuture Build VLAP (to be acquired between 2020 and 2025), and the Runway 5 End RPZ clearing.Alternative B4 would newly expose the John Wickes School (SCH524) to noise levels of DNL 65 dB and abovewhen compared to the No-Action Alternative in 2025 (Table 5-10). The John Wickes School has already beensound insulated as part of a previous sound insulation effort under the Part 150 NCP.Significant Impacts – 2020 and 2025: Under Alternative B4, several areas would experience a significant increase innoise levels (increase of at least DNL 1.5 dB at or above DNL 65 dB). Residential land (169 parcels totalingapproximately 30 acres consisting of 174 units in 2020, and 108 parcels totaling approximately 18.5 acres consisting of108 units in 2025) would be affected by significant increases in noise due to Alternative B4 when compared to the No-Action Alternative (Table 5-41). These residential areas are located immediately adjacent to the Runway 5 End(Figure 5-22). Residences on these parcels would be eligible for sound insulation mitigation.Chapter 5 - Environmental Consequences 5-61 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
