Resi dences exposed to noise levels 70 dB and above are not consi deredsignificantl y impacted; however, those residences would be eligible for land acquisition. See Tables 6-5 and 6-6 for mitigation proposed for i mpacts that are not defi ned assignifi cant.The level of documentati on, either HABS/HAER or RIHRA will be determined through consultati on.Chapter 6 – Mitigation 6-42 July 2011\\Mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH06_Mitigation_JUL_2011.doc
