• Project Truck Traffic Ldn Values Within Bedrooms - Windows Closed: With <br /> bedroom windows closed, Ldn values associated with the project alone are predicted to <br /> be below the 45 db Ldn County interior noise level standard within residences located <br /> along East River Road. Less than significant. <br /> • Project Truck Traffic Increase in Ldn at Outdoor Activity Areas: The project-related <br /> increase of approximately 2 dB Ldn at outdoor activity areas due to nighttime passages <br /> of project trucks is not considered meaningful as it would not correlate to impacts <br /> received by persons within their residences during the hours or project noise generation. <br /> Less than significant. <br /> • Project Truck Traffic Increase in Hourly Noise Levels: Although the project will <br /> occasionally result in substantial increases in average noise levels during the quietest <br /> hours of the night, those increases at outdoor areas would not necessarily translate to <br /> adverse noise impacts. Due to the very low anticipated use of outdoor activity areas <br /> between the hours of midnight and 2 a.m., the noticeable project-related noise increase <br /> during those hours is not expected to adversely affect those outdoor activity areas. <br /> Less than Significant. <br /> Environmental Noise Analysis <br /> Munn&Perkins Expanded Hours of Operations-San Joaquin county <br /> Page 36 <br />
