City of San Leandro Alvarado Commerce Center Project 68 Table 8 Significance of Changes in Operational Roadway Noise Exposure Existing Noise Exposure (Ldn or Leq in dBA) Allowable Noise Exposure Increase (Ldn or Leq in dBA) 45-50 7 50-55 5 55-60 3 60-65 2 65-75 1 75+ 0 Source: Federal Transit Administration 2006. The traffic analysis found the project would generate 126 daily trips, 55 A.M. peak hour trips, and 71 P.M. peak hour trips (TJKM 2017: Appendix D). Table 9 shows the net increase in roadway traffic volumes along the studied roadway segments with the greatest increase in traffic for the A.M. and P.M. peak hours.

As discussed under the Roadway Noise setting section, a 10 percent increase in vehicle traffic would result in an increase in traffic noise of approximately 0.4 dBA Leq. As the project would increase traffic volumes on nearby streets by less than 10 365
