The analysis is based on the DEIS Level 5 aircraft operations and fleet mix, using INM Version 6.0. Some homesexposed to noise levels DNL 65 dB and above may have already received sound insulation treatment under the NCP. Refer to Figure 3-8.2 Properties would be eligible for acquisition under a voluntary land acquisition program. Does not include neighborhood rounding of noise contours identifyingeligible parcels.3 Wetland impacts are associated with the Runway 34 RSA enhancements.4 Refer to Figure 3-9.5 Eligible for listing on the National Register of Historic Places.6 Listed on the National Register of Historic Places.7 Construction costs for Alternative B3 South are less than Alternative B4 due to a shorter runway extension. Mitigation costs would be slightly less due to fewerresidential units to be acquired and sound insulated.Chapter 3 – Alternatives Analysis 3-28 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH03_Alternatives_JUL_2011.doc
