Staff warns San Antonio Road Complete Streets grant may require far more work and money than application suggests

Summary
Traffic engineer Steven Sun told the commission the 1.9-mile San Antonio Road Complete Streets grant is federalized and will require phased FHWA/Caltrans approvals, ADA upgrades and structural pavement repairs that are not in the original concept documents; staff said a detailed re-evaluation of scope and cost is needed before proceeding.
Steven Sun, the city's traffic engineer, gave an informational briefing on the North San Antonio Road Complete Streets project and told the commission the federal grant award covers a 1.9-mile corridor from Foothill to El Camino but relies on preliminary renderings rather than engineering-level documents.
Sun said the grant intent includes a separated bicycle facility, high-visibility crosswalks, narrowed travel lanes for traffic calming and bus-stop integration, but cautioned that federal participation means the city must follow FHWA and Caltrans procedures for each phase of work. "Anytime you have a federally funded project... you have to follow the federal requirements," he said.
The staff presentation identified two immediate concerns: the application does not include structural pavement repair scope and it does not document required ADA upgrades for affected sidewalks and crossings. Sun described field observations of alligator cracking and rutting in places that would carry the proposed bike facilities and argued that those subgrade and pavement issues would need repair before installing bike lane hardware.
Sun also flagged budget uncertainty. He said the city's current estimate in materials he reviewed is roughly $9.7 million for work tied to the grant but described that figure as incomplete and offered a preliminary "knee-jerk" re-evaluation that the full cost could rise into the mid-teens of millions of dollars once pavement repair and ADA compliance work are included.
Given the federalized nature of the grant, Sun outlined the required approval steps—preliminary engineering/design (PE), environmental assessment (EA), right-of-way certification and construction authorization—and stressed the timing and documentation needed to secure reimbursement from the federal program. He said each phase generally carries a multi-year authorization window and that failing to demonstrate progress risks the project becoming inactive and losing funds.
Commissioners asked for more detail and data; staff said it will mark locations for needed structural repairs, collect or assemble a revised cost estimate, and return to the commission with findings. Sun said the city must decide whether to seek additional funding partners, ask the grant program to reassess match responsibilities, or withdraw from the project if the true scope and cost prove infeasible.
The presentation was informational; no formal action was taken. Staff said it will follow up with a detailed scope-and-cost analysis and then put the project back on a future agenda for formal direction or action.
