No subsidized housing developments wouldbe exposed to noise levels greater than DNL 65 dB for Alternative B2 in 2015; in addition no subsidized housingunits would be newly exposed and none would be exposed to a significant noise increase.Significant Aircraft Noise Impacts – 2015: There are no significant noise impacts for any residential areas ornon-residential noise-sensitive sites for Alternative B2 in 2015, as shown in Tables 5-14 and 5-15, and Table 5-10,respectively.Aircraft Ground Noise (Integrated Cargo Facility Operations) - 2015There are no differences in the aircraft ground noise levels predicted at the Airport between the No-ActionAlternative and Alternative B2 in 2015, as no changes would be made to the Integrated Cargo Facility until after 2015.Vehicular Traffic Noise Impacts – 2015In 2015, the off-Airport roadway improvements under Alternative B2 consist of Partially Relocated Airport Road. Thewestern end of Partially Relocated Airport Road would terminate at a new intersection with Post Road in the vicinityof Tennessee Avenue. From Post Road, the roadway would extend to the southeast, bisecting the rental car facility,and tie into the existing Airport Road in the vicinity of Evergreen Avenue. Table 5-16 provides a summary ofprojected traffic noise levels and noise impact in the neighborhoods affected by Partially Relocated Airport Road.These neighborhoods are generally located at the west end of Airport Road along Post Road.As shown in Table 5-16, in 2015, Partially Relocated Airport Road would impact seven more dwelling units thanthe No-Action Alternative along the west side of Post Road between Kentucky and Delaware Avenues.However, along the west side of Post Road from Haverford to Pell Avenue, the number of housing unitsexposed to traffic noise levels that approach or exceed the relevant FHWA NAC for Activity Category B wouldremain the same. On the east side of Post Road, one housing unit located between existing Lincoln and AlabamaAvenues would be impacted in 2015, but would be acquired by 2020 as a result of Fully Relocated Airport Road.Chapter 5 - Environmental Consequences 5-25 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
