Assembly Member Arambula's proposal to expand California's definition of "major transit stop" would extend certain environmental review exemptions to residential and mixed-use projects near high-speed rail stations. The measure modifies the California Environmental Quality Act (CEQA) framework by adding planned or existing high-speed rail stations to the list of qualifying transit facilities, which currently includes rail stations, ferry terminals, and major bus route intersections.

Under existing CEQA provisions, residential projects on infill sites and transit priority projects located within a half-mile of major transit stops may qualify for streamlined environmental review. The definition currently encompasses existing rail or bus rapid transit stations, ferry terminals served by transit, and intersections of major bus routes with peak-period service frequencies of 15 minutes or less. This amendment would extend these potential exemptions to developments near high-speed rail stations, whether planned or operational.

The measure designates implementation as a state-mandated local program, requiring lead agencies to evaluate high-speed rail stations when determining a project's eligibility for CEQA exemptions. Local agencies and school districts maintain authority to levy service charges, fees, or assessments to cover any associated costs, with no state reimbursement required for implementation.
