For the Alternative B2 cases, the number of impacted housing units is due toboth traffic noise levels that approach or exceed the relevant FHWA NAC and that cause a substantial increase over baseline levels.3 See Figure A.4-20 in DEIS Noise Supporting Attachment A.11, Supporting Report Graphics.4 See Figure A.4-21 in DEIS Noise Supporting Attachment A.11, Supporting Report Graphics.Table 5-20Alternative B2: 2025 Summary of Traffic Noise Impacts by NeighborhoodTotal Number of HousingUnits 1 Exposed toLoudest-hour Leq in dBANoise ImpactBaseline No-Action Alt.
