T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation5.3.5 Temporary Impacts from Short-Term Construction ActivitiesNoise levels would increase temporarily during the short-term construction activities associated withAlternatives B2 and B4. The degree of noise impact during construction would be a function of the number andtypes of equipment being used, and the distances between the construction equipment and the noise-sensitiveareas. Overall construction noise levels are governed primarily by the noisiest pieces of equipment operating ata given time. Table 5-28 provides typical maximum sound levels associated with various types of constructionequipment. During any particular activity, multiple pieces of equipment may be operating simultaneously andfor various durations throughout the construction period. Therefore, noise impact experienced by localresidents as a result of construction activities is not expected to occur during sleeping hours. Long-termdisruptions to aircraft traffic due to runway and taxiway closures are not expected to occur, and, thus, therewould be no increases in aircraft noise associated with construction.5.3.5.1 Alternative B2Noise levels would increase during short-term construction of Alternative B2. Construction activities areanticipated to begin in 2014 with the construction of Partially Relocated Airport Road and the Runway 16-34 RSAenhancements. In 2015, noise levels would increase during short-term construction of Airport Road and theRunway 16-34 RSA enhancements; however, these areas are not close to residential neighborhoods and would notimpact residents. Construction would extend through the end of 2020 depending on the program improvementelement under construction. Temporary increases in noise levels from construction activities would primarily beexperienced in neighborhoods north of the Airport (Norwood, Lincoln Park, Hoxie, and Spring Green), due to theconstruction of extended Runway 5-23 and Fully Relocated Airport Road. Neighborhoods to the south includingGreenwood, Oak Grove and Strawberry Field would be impacted by temporary increases in noise fromconstructing the extension of the Runway 5 End. Runway 5-23 and associated taxiway construction would resultin an increase in noise on both the north and south side of the Airport.Alternative B2 involves the construction of Fully Relocated Airport Road, which would be located in theneighborhood just north of the Airport. Runway 5-23 and associated taxiway construction would result in anincrease in noise on both the north and south side of the Airport. Residences along Airport property near theRunway 5 End of the Airport would experience some construction noise.Construction activity would mainly occur during normal working hours on weekdays. Therefore, noise impactexperienced by local residents as a result of construction activities is not expected to occur often during sleepinghours. Long-term disruptions to aircraft traffic due to runway and taxiway closures are not expected to occur,and, thus, there would be no increases in aircraft noise related to the construction activities.Chapter 5 - Environmental Consequences 5-38 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc

Construction activities forAlternative B4 are anticipated to begin in 2013 with the construction of partially relocated Airport Road and theRunway 16-34 enhancements. In 2015 and 2020, noise levels would temporarily increase during the short-termconstruction activities of Alternative B4. Short-term construction activities are anticipated to extend through theend of 2020, depending on the program element under construction, and would primarily be experienced inneighborhoods south of the Airport (Oak Grove, Greenwood Park, north side of Buttonwoods and StrawberryFields) due to the extension of Runway 5-23 to the south and Realigned Main Avenue. Lesser amounts oftemporary construction noise would be experienced north of the Airport (Hillsgrove and Lincoln Park) due tothe construction of the new Integrated Cargo Facility.Construction activity would mainly occur during normal working hours on weekdays. Therefore, noise impactexperienced by local residents as a result of construction activities is not expected to often occur during sleepinghours. Long-term disruptions to aircraft traffic due to runway and taxiway closures are not expected to occur,and, thus, there would be no increases in aircraft noise related to the construction activities.Chapter 5 - Environmental Consequences 5-39 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
