T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationUnder Alternative B2, areas that are currently zoned residential would not be compatible with predicted noiselevels according to federally-defined land use compatibility regulations for noise levels. 324 Table 5-47 presentsresidential zoning district acreage that would be exposed to noise levels of DNL 65 dB and above forAlternative B2 in 2020 and 2025 compared to the No-Action Alternative. Figure 5-24 shows the Alternative B2noise contours for 2015, 2020, and 2025 with generalized zoning.Table 5-47Alternative B2: Residential Zoning Districts Exposed to DNL 65 dB and Above (acres)No-Action Alternative Alternative B2 Change (%)Zoning District 2015 2020 2025 2015 2020 2025 2015 2020 2025Residential 1 228 286 387 230 308 383 1% 8% -1%Sources: RIGIS; Field verification by VHB, Inc., 2005; City of Warwick Assessor’s Parcel Data.1 Includes Residence A-7 and A-10 zoning districts.As discussed in Section 5.3, Noise, while the runway use and number of operations would not change for Alternative B2in 2015 compared to the No-Action Alternative, the runway thresholds would change under Alternative B2 comparedto the No-Action Alternative due to the runway safety area enhancements to Runway 16-34. These changes in turnwould result in a one percent increase in the extent of residential zoning districts that would be exposed to noise levelsof DNL 65 dB and above. Under Alternative B2 in 2020, there would be an increase of 22 acres, or eight percent, in theamount of residentially zoned land that would be exposed to noise levels of DNL 65 dB and above compared to the No-Action Alternative. In 2025, there would be a decrease of four acres, or one percent, in the amount of residentially zonedland that would be exposed to noise levels of DNL 65 dB and above compared to the No-Action Alternative. AlternativeB2 would change the existing land use by introducing a non-compatible use (airport operations) within residentialareas. It is anticipated that land will be made reasonably consistent with local zoning through implementation of RIAC’sPart 150 NCP, including sound insulation and land acquisition for noise mitigation, as documented inChapter 6, Mitigation.Alternative B4Under Alternative B4, a number of land use changes to the City of Warwick’s current zoning would be needed,including:• By 2015, the RSA enhancements for Runway 16, would require that land currently zoned residential,business, or industrial be converted to Airport land.• By 2015, the extension of Runway 5-23, would require that land currently zoned office is converted toAirport land.• The Future Build VLAP, would require that land currently zoned residential is converted to Airport land.(For the purposes of the EIS, properties are assumed to be acquired between 2015 and 2020 for noiseimpacts in 2015, and between 2020 and 2025 for noise impacts in 2020. However, it is RIAC’s intention tobegin to acquire residential parcels as soon as 2012, if funding is available).• The land acquisitions for the FAA-recommended RPZ clearing, would require that land currently zonedresidential be converted to Airport land.324 14 CFR Part 150, Airport Noise Compatibility Planning, paragraph 150.7.Chapter 5 - Environmental Consequences 5-66 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
