T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationLand Use Compatibility - 2015Figure 5-21 shows the land uses that would be exposed to the DNL 65 dB and above noise levels in 2015 forAlternative B4 compared to the No Action Alternative. The residential areas that would be exposed to DNL 65 dBand above under Alternative B4 in 2015 are presented in Table 5-44. In comparison to the No-Action Alternative, in2015, Alternative B4 would result in an increase of noise-sensitive land uses (residential) newly exposed tofederally-defined incompatible noise levels of DNL 65 dB and above. 301In 2015 under Alternative B4, the amount of residential land exposed to DNL 65 dB and above would increaseby 93 parcels totaling 27 acres (representing an approximately 18 percent increase in land area) in the totalamount of residential land area that would be incompatible compared to the No-Action Alternative. Thisincrease is due to an increase in operations and because it is assumed that residential acquisitions for noisemitigation would not to be acquired before 2015.Table 5-44Alternative B4: Residential Land Exposed to DNL 65 dBCompared to the No-Action Alternative (2015)2015Alternative Parcels AcresNo-Action Alternative 914 148Alternative B4 1,007 175Alternative B4 Change from No-Action AlternativePercent Change+93+10%+27+18%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 abovewere determined after first excluding the non-project-related residential land acquisitions that would be acquired underthe Completed and Current Part 150 VLAPs, and for project-related mandatory (for construction).In 2015 under Alternative B4, one non-residential noise-sensitive site, Baha’i Faith (PW039), would be exposedto noise levels that would make the site eligible for sound insulation (DNL 65 dB and above when compared tothe No-Action Alternative); however, this site has been sound insulated as part of a previous sound insulationeffort under the Part 150 NCP.Significant Impacts - 2015: Under Alternative B4, several noise-sensitive areas (residential land uses) wouldexperience a significant increase in noise levels (increase of at least DNL 1.5 dB at or above DNL 65 dB).Residential land uses (180 parcels totaling approximately 32 acres consisting of 184 residential units) would bethe largest land area affected by significant increases in noise when compared to the No-Action Alternative in2015 (Table 5-41, presented previously). These residential areas are located immediately adjacent to theRunway 5 and 23 Ends (Figure 5-21). These residences would be eligible for sound insulation mitigation.301 14 CFR Part 150, Noise Compatibility Planning.Chapter 5 - Environmental Consequences 5-60 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
