T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationEffects on Peak Hour Traffic Flow (Level of Service) - 2015Morning and evening peak hour traffic flow at one intersection would improve under Alternative B4 whencompared with the No-Action Alternative:• Post Road (U.S. Route 1) at Partially Relocated Airport Road and Ann & Hope driveway – In 2015, morningpeak hour operations would improve from LOS D under the No-Action Alternative to LOS C underAlternative B4. The relocated intersection would be designed to accommodate all movements at theintersection, including vehicles entering and exiting the relocated Ann & Hope driveway.Four locations with LOS E or LOS F capacity constraints under the No-Action Alternative would continue tooperate at LOS E or LOS F levels under Alternative B4:• Post Road (U.S. Route 1) at Lincoln Avenue – During the evening peak hour, this intersection would operateat LOS F under the No-Action Alternative and under Alternative B4.• Airport Road at Evergreen Avenue – During the evening peak hour, this intersection would operate atLOS F under the No-Action Alternative and under Alternative B4.• Airport Road at Commerce Drive – During the evening peak hour, this intersection would operate at LOS Funder the No-Action Alternative and under Alternative B4.• Airport Road at Warwick Avenue – During the morning and evening peak hours, this intersection wouldoperate at LOS E under the No-Action Alternative and under Alternative B4.Alternative B4 would result in LOS E or LOS F conditions at one location:• Post Road (U.S. Route 1) at Relocated Delivery Drive – Relocating Delivery Drive would create a newunsignalized driveway along Post Road. The only vehicles using Delivery Drive would be Airport deliveryvehicles (approximately 35 vehicles per hour during the morning and evening peak hours). General trafficwould be prohibited from entering or exiting the Airport at this location. The intersection of Post Road andRelocated Delivery Drive would operate at LOS F during the evening peak hour in 2015. However, theLOS F only applies to the 35 vehicles exiting Delivery Drive (an average of one vehicle every two minutes).General traffic on Post Road would not be affected. 363Effects on Freeway Segments and Ramps - 2015The results show that there would be no freeway segment or ramp merge and diverge area capacity constraintson the Airport Connector or Route 37 and that there would be no locations that would degrade to LOS E or LOSF as a result of Alternative B4 in 2015.Parking Impacts - 2015In 2015, Alternative B4 would not impact the parking supply on the Airport. Alternative B4 would requireacquisition of property privately owned by Airport Valet (at 717 Airport Road) that is currently used for valetparking and holds approximately 180 vehicles. This property would have to be acquired to construct the363 Of the 35 vehicles, approximately 5 vehicles are expected to turn left and the remaining 30 vehicles are expected to turn right, based on observed trafficmovements. The 35 vehicles per hour average to about one vehicle every two minutes.Chapter 5 - Environmental Consequences 5-135 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
