Senators Wiener and Arreguín's transportation funding proposal would authorize a new revenue measure for the San Francisco Bay area's transportation system, building upon the Metropolitan Transportation Commission's 2024 regional engagement process. The measure aims to generate dedicated funding to maintain and enhance public transportation services across the nine-county region.

The bill directs the Metropolitan Transportation Commission (MTC), the Bay area's regional transportation planning agency, to continue its stakeholder engagement process to determine the revenue measure's specific parameters, including its geographic scope and funding mechanisms. This process will incorporate input from existing transit districts, local governments, and community stakeholders to shape the final funding framework.

While the proposal establishes the broad authority for a regional transportation revenue measure, it leaves key details - including the funding structure, revenue targets, and allocation methods - to be determined through the ongoing stakeholder engagement process. The measure would operate within the existing transportation governance framework, with the MTC maintaining its role as the regional planning authority and local transit districts continuing to provide public transportation services under their current mandates.
