Transportation Impacts A summary of the transportation impacts and proposed mitigation relating to the City of Pleasanton are provided below. A more detailed evaluation and analysis for the region is detailed in Chapter 3B of the DEIR. Freeway Level-of-Service (2025) • Conventional BART — During the AM peak period, Hopyard Road and Dougherty Road will see increased levels of traffic. It is expected that new auto trips to the Dublin/Pleasanton Bart Station are created with the movement of Livermore/San Joaquin County based trips to the Livermore Station. • DMU/EMU — The transportation impacts resulting from the DMU alternative will be similar to that of the Conventional BART project, except at a smaller magnitude. • Express Bus — The 1-580 segment from Hacienda Drive to Tassajara Road/Santa Rita will experience will result in an unacceptable level of service due to this alternative in the AM westbound direction. The freeway volume to capacity ratio in this segment is predicted to degrade by more than 2 percent as compared to a No Project condition. Significant and Unavoidable. • Enhanced Bus Service — This alternative experiences a less than significant impact. Freeway Level-of-Service (2040) • Conventional BART — Significant and unavoidable impacts are expected in Livermore due to the increase in traffic expected to and from the Isabel Station. Freeway segments in Livermore are predicted to degrade by more than 2 percent compared to the No Project condition. (I would note that this doesn't make much sense — the freeway is assumed to be at capacity in 2040 no project conditions, so adding a Bart station at Isabel shouldn't create additional freeway capacity). • DMU/EMU — The transportation impacts resulting from the DMU alternative will be similar to that of the Conventional BART project, except at a smaller magnitude. • Express Bus/BRT - There are no impacts to the general freeway segments. • Enhanced Bus Service — There are no impacts to the general freeway segments. Freeway HOV/Express Lane (2025) • Conventional BART —HOV/express lane segments are expected to operate at unacceptable level of service during both peak periods. However, they are predicted to operate similar to the No Project Condition. • DMU/EMU — Significant and unavoidable impacts are expected on the segment between Tassajara/Santa Rita Road and Fallon/EI Charro Road. The freeway volume to capacity ration in this segment is predicted to degrade by more than 2 percent as compared to a No Project Condition. • Express Bus — The transportation impacts resulting from the Express Bus/BRT alternative will be similar to that of the Conventional BART project. Therefore the impact is Less than Significant. • Enhanced Bus Service - The transportation impacts resulting from the Express Bus/BRT alternative will be similar to that of the Conventional BART project. Therefore the impact is Less than Significant.
