Based on the traffic analysis contained in the EIR, the following impacts will be significant and unavoidable: • Traffic o Existing Plus Project Conditions • Increase average vehicle delay at two unsignalized intersections already operating at an unacceptable level of service ("LOS") by more than threshold of significance • Degrade the LOS at one unsignalized intersection from an acceptable to an unacceptable LOS • Degrade the level of service at one freeway off-ramp (diverge) from an acceptable to an unacceptable LOS o Year 2013 Plus Project(Phase I) Conditions • Increase traffic volumes at three freeway ramps by more than threshold of significance o Year 2021 Plus Project(Phases I & 11) Conditions • Increase average vehicle delay at two unsignalized intersections already operating at an unacceptable LOS by more than threshold of significance • Degrade the LOS at one unsignalized intersection from an acceptable to an unacceptable LOS and increase the average vehicle delay by more than threshold of significance • Increase average vehicle delay at three unsignalized intersections already operating at an unacceptable LOS by more than threshold of significance o Year 2035 Plus Project(Phases 1 & II) Conditions • Increase average vehicle delay at two signalized intersections already operating at an unacceptable LOS by more than threshold of significance • Increase average vehicle delay at five unsignalized intersections already operating at an unacceptable LOS by more than threshold of significance • Degrade the LOS at one unsignalized intersection from an acceptable to an unacceptable LOS and increase the average vehicle delay by more than threshold of significance • Increase average vehicle delay at one unsignalized intersections by more than threshold of significance • Degrade the LOS at one signalized intersection from an acceptable to an unacceptable LOS. • Add more than 100 trips to six freeway segments already operating at an unacceptable LOS • Add more than one percent traffic to four freeway ramps already operating at an unacceptable LOS • Increase traffic volumes at five freeway ramps by more than one percent threshold of significance • Cause eastbound vehicles stopped at the Roth Road eastern Oakland Subdivision at-grade rail crossing to queue as far back as the 1-5 interchange at Roth Road, a condition which will also exist under the 2035 No-Project Conditions. Some of the intersections listed above are not located within the County's jurisdiction. Impacts to the intersections listed above which lie outside of the County's jurisdiction will be less than significant if San Joaquin County PA-0900184 & 185\Union Pacific �, Community Development Page 15
