Figure 5-9 shows the location of non-residential noise-sensitive locations within the broadestlimit of the 2025 DNL 60 dB contour of all of the Alternatives.Aircraft Ground Noise (Integrated Cargo Facility Operations) - 2015There are no changes in the noise levels predicted at the Airport between the No-Action Alternative andAlternative B4 in 2015, as no changes would be made to the Integrated Cargo Facility until after 2015.Vehicular Traffic Noise Impacts – 2015The same number of housing units would be impacted by vehicular traffic noise for Alternative B4 in 2015 whencompared to the No-Action Alternative. Vehicular traffic noise impacts in the neighborhoods would result fromthe Partially Relocated Airport Road and Realigned Main Avenue under Alternative B4. Main Avenue would berealigned to the south almost to Stevens Avenue between Gorham and Palace Avenues andInman/Buttonwoods Avenues. In 2015, the off-Airport roadway improvements under Alternative B4 consist ofPartially Relocated Airport Road along an alignment using Hasbrouck Avenue. The western end of PartiallyRelocated Airport Road would terminate at a new intersection with Post Road. From Post Road, the roadwaywould extend east along Hasbrouck Avenue, then southeast, connecting with existing Hallene Road and thenexisting Airport Road between Evergreen and Commerce Avenues. The neighborhoods near Partially RelocatedAirport Road are generally located along Post Road near the western end of the existing Airport Road.Table 5-23 summarizes projected exterior traffic noise levels and noise impact in the neighborhoods affected byPartially Relocated Airport Road and Realigned Main Avenue under Alternative B4. DEIS Noise SupportingAttachment A.4, Vehicular Traffic Noise Technical Report, provides a detailed assessment of program-relatedtraffic noise, including detailed tables of computed traffic noise levels for each alternative.Chapter 5 - Environmental Consequences 5-32 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
