T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationImpacts to the eligible airport historic district, Hangar No. 1, Hangar No. 2, and Winslow Park are alsodescribed in Chapter 7, Final Section 4(f)/Section 6(f) Evaluation.Indirect ImpactsFigures 5-37 and 5-38 show the location of Section 4(f)-protected historical properties and parks in relation topredicted noise contours for Alternative B4 in 2015, and 2020 and 2025, respectively. Alternative B4 would notresult in constructive uses of historical properties due to noise impacts. The Rhode Island State AirportTerminal, Hangar No. 1, Hangar No. 2, and the eligible airport historic district would experience noise levelsabove DNL 65 dB (Table 5-98). However, a quiet setting is not a characteristic that qualifies these resources forinclusion in the NRHP. These historical properties are all on-Airport and in aviation-related uses.Alternative B4 would not result in a change of setting for Hangar No. 2. As Airport Road would not be fullyrelocated under Alternative B4, the public's view of Hangar No. 2 would not be obstructed under thisAlternative. All other historical architectural properties are located at least one mile from the Airport and arebuffered from any potential visual impacts.Results from the GIS mapping and noise analysis indicate that Winslow Park would experience a significantchange in noise levels (an increase of at least DNL 1.5 dB at or above DNL 65 dB) in 2015, 2020 and 2025 underAlternative B4 (Table 5-99). However, the increased noise levels at what is left of Winslow Park would not beconsidered a constructive use because the noise levels would still be below DNL 75 dB, which is a noise levelconsidered compatible with outdoor recreational use. 397 Therefore, there are no constructive uses of Section 4(f)parks or recreation areas under Alternative B4 due to noise. Under Alternative B4, there would be no changes inaccess to parks and recreational areas that would result in constructive use.Significant Impacts: Alternative B4 would result in a physical use (removal) of Hangar No. 1, a contributingelement of the eligible airport historic district. In addition to the removal of Hangar No. 1, Alternative B4 alsocalls for airside enhancements that will further alter the overall historical configuration of the runways andtaxiways that are included as contributing elements to the eligible airport historic district resulting in a physicaluse of the district. Construction of the new Integrated Cargo Facility under Alternative B4 would directlyimpact the landscaping of the Rhode Island State Airport Terminal resulting in a physical use. City ownedrecreational areas within Winslow Park would be converted to aviation-related use resulting in a physical use ofa public recreational resource.5.9.4.4 Summary of Non-Impacted Section 4(f) ResourcesThe following Section 4(f)-protected historical resources within the Study Area would not be used as a result ofthe No-Action Alternative or Alternatives B2 and B4:• Pawtuxet Village Historic District• Rhodes (Christopher) Historic Site• John Waterman Arnold Historic Site397 Table 1-Land Use Compatibility with Yearly Day-Night Average Sound.
