Los Angeles County Metropolitan Transportation Authority.

Senator Allen's proposal to restructure the Los Angeles County Metropolitan Transportation Authority board would expand its membership from 14 to 18 directors beginning January 1, 2029. The reconstituted board would include the Los Angeles County Executive and three public members appointed by that office, while maintaining existing positions held by the Board of Supervisors, the Mayor of Los Angeles, city representatives, and a nonvoting gubernatorial appointee.

The legislation preserves the current geographic representation system, under which four board members are selected from defined sectors across Los Angeles County: North County/San Fernando Valley, Southwest Corridor, San Gabriel Valley, and Southeast Long Beach. These appointments continue to be made by the Los Angeles County City Selection Committee through population-weighted voting among cities in each sector. The bill also retains provisions requiring board restructuring if Los Angeles City's population falls below 35% of the county total, in which case one mayoral appointee would be replaced by an additional city representative.

Under the measure, LA Metro must submit plans to the Legislature within 60 days to revise board composition if the county charter is amended to change the number of supervisors or eliminate the county executive position. The bill designates these new administrative requirements as state-mandated local programs, making Los Angeles County eligible for cost reimbursement through established statutory processes.
