Resi dences exposed to noise levels70 dB and above are not considered significantly impacted; however, those residences would be eligible for land acquisiti on. See Tables 6-5 and 6-6 formitigation proposed for impacts that are not defined as signifi cant.2 The level of documentati on, either HABS/HAER or RIHRA will be determined through consultati on.Chapter 6 – Mitigation 6-54 July 2011\\Mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH06_Mitigation_JUL_2011.doc
