T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation5.4.8.1 Significant Land Use ImpactsBoth Alternatives B2 and B4 would result in a significant increase in noise (increase of at least DNL 1.5 dB at orabove DNL 65 dB) to noise-sensitive (residential) land uses (in 2020 and 2025 only under Alternative B2, and inall analysis years for Alternative B4 due to the expedited construction schedule). Under Alternative B4 in 2015,180 residential parcels totaling approximately 32 acres would be affected by significant increases in noise whencompared to the No-Action Alternative (Table 5-41). In both 2020 and 2025, Alternative B2 would expose lessresidential land uses to significant noise impacts (71 parcels totaling approximately 11.5 acres in 2020 and48 parcels totaling approximately seven acres in 2025) than Alternative B4 (169 parcels totaling approximately30 acres in 2020 and 108 parcels totaling approximately 18.5 acres in 2025) (Table 5-41). This is because underAlternative B2, more residential acquisitions are required for construction of Fully Relocated Airport Roadnorth of the Airport and because under Alternative B4 the extension of Runway 5-23 is to the south of theAirport would result in increased aircraft operations over a predominantly residential area. As discussed underSection 5.3, Noise, all noise-sensitive land uses impacted by a significant increase in noise would be eligible forsound insulation mitigation.5.4.8.2 Land AcquisitionIn 2020 under the No-Action Alternative, it is assumed that 59 parcels at the Runway 5 End and 56 parcels at theRunway 23 End would be acquired under the Current Part 150 VLAP. By 2020, Alternative B2 would result inthe acquisition of 247 residential, commercial, agriculture, and undeveloped parcels totaling76 acres for all land acquisition types (construction, noise mitigation, and FAA-recommended RPZ clearing),which is greater than the total amount of land acquisitions for Alternative B4 (180 residential and commercialparcels totaling approximately 40 acres).Cumulatively, Alternative B4 would result in the least amount of cumulative land use changes compared toAlternative B2 for both commercial and industrial (including agricultural) and residential land uses. AlternativeB4 would have fewer commercial land acquisitions resulting in the least amount of commercial and industrialland use changes to the north of the Airport compared to Alternative B2 (23 parcels containing 12 businessesversus 53 parcels containing 38 businesses, respectively). Alternative B4 results in fewer residential landacquisitions than Alternative B2 for construction, RPZ areas (Alternative B4 does not include Runway 23 EndRPZ area acquisitions), and the Future Build VLAP (272 parcels containing 275 units versus 285 parcelscontaining 372 units, respectively).5.4.8.3 Land Use CompatibilityRefer to Section 5.4.8.1, Significant Land Use Impacts, for a discussion of significant impacts related to compatibleland use. Between 2015 and 2020, the area of residential land (acres) that would be exposed to noise levels ofDNL 65 dB and above would increase by approximately 26 percent under the No-Action Alternative. Between2020 and 2025, the area of residential land (acres) that would be exposed to noise levels of DNL 65 dB and abovewould increase by approximately 37 percent under the No-Action Alternative.Under Alternative B4, residential land uses would become incompatible sooner than under Alternative B2 (by2015) due to the expedited construction schedule for Alternative B4. In 2020 and 2025, Alternative B4 wouldexpose slightly more parcels to noise levels of DNL 65 dB and above than Alternative B2, because underChapter 5 - Environmental Consequences 5-73 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
