City Council - December 10, 2025

Council postpones grade-separation choices to Dec. 15

The Palo Alto City Council voted 6-0 to continue its review of rail grade-separation alternatives at Churchill Avenue, Meadow Drive and Charleston Road to Dec. 15. The council made no final selection, leaving staff to provide additional information before members decide which options should advance into 15% design and environmental review.

At Meadow Drive, staff compared a hybrid design that would raise the railroad and lower the roadway with an underpass that would retain the tracks at their current elevation and fully depress the street. Staff said both would improve vehicle operations, with the underpass producing greater operational benefits but restricting some movements and requiring more circuitous trips. At Charleston Road, the choices included a hybrid and underpass variations using either a roundabout or a direct-access ramp.

Staff's preliminary property analysis identified one potential partial acquisition for the Meadow hybrid, compared with two full acquisitions affecting 16 dwelling units and six partial acquisitions for the underpass. At Charleston, the hybrid could require two partial acquisitions, compared with one full and 23 partial acquisitions for the direct-access underpass or three full and 26 partial acquisitions for the roundabout option.

For Churchill, council members expressed preliminary support for a partial vehicular underpass rather than closing the crossing, along with a pedestrian and bicycle ramp along Alma Street instead of at Seal Avenue. Staff said the Alma alignment would provide a more direct route toward Palo Alto High School and have fewer property and parking effects. The council took no final action on either choice.

Council members requested network-level travel-time comparisons for drivers, pedestrians and cyclists, along with clearer information about construction duration, bicycle routing and potential property acquisitions. Staff said detailed construction schedules and validated updated cost estimates were not yet available, but preliminary bicycle travel times could be provided for the continued discussion. More extensive constructibility, utility and cost analysis would occur during 15% design.

Public comments reflected sharp differences over the preferred designs. Some speakers urged the city to advance hybrids at Meadow and Charleston because of the underpasses' property and neighborhood effects, while others wanted the underpasses retained for further study because of their potential traffic benefits. Speakers also raised construction disruption, affordability, pedestrian and bicycle safety, eminent domain and possible reconsideration of a viaduct or Churchill alternatives.

Staff expects 15% design work to refine property impacts, construction methods and market-based costs over about six months. Drawings and updated project-delivery estimates are anticipated in mid-2026, with 35% design required by the end of 2027 under federal grant funding.
