LOS ANGELES — A group of elected officials, led by Los Angeles County supervisors, urged voters Monday to support Measure G, a proposed initiative they say will reform county government.

With Election Day Tuesday, Supervisors Lindsey Horvath, Janice Hahn and Hilda Solis renewed their call for voters to pass Measure G. The proposal would expand the Board of Supervisors from five to nine members, establish an elected county executive, create an independent ethics commission and introduce open budget hearings.

Several elected officials and community leaders, including Rep. Judy Chu, D-Pasadena, Rep. Tony Cárdenas, D-Pacoima, AAPI Equity Alliance executive director Manjusha Kulkarni, CHIRLA executive director Angélica Salas, and Nichelle Henderson, president of the LA Community College District Board, joined the supervisors.

"This morning's strong show of support for Measure G proves just how committed our communities are to building a better, more accountable Los Angeles County," Horvath said.

"A 'yes' vote on Measure G is a vote for transparency, for equity, and for a government that truly represents all of us," she added.

Currently, 10 million people in the county are represented by five people on the board. By expanding the board, the goal is to diversify the decision-making process and ensure the county leadership reflects the population, according to officials.

"The composition of the Board of Supervisors must reflect the increased diversity of Los Angeles County's population," Solis said Tuesday. "Measure G is about giving voters the opportunity to shape their county government, ensuring greater transparency, accountability and representation."

If approved by voters, Measure G's changes would be implemented gradually, starting in 2026 with the establishment of an ethics commission, followed by the election of a county CEO in 2028.

Following the 2030 U.S. Census and a redistricting process, the board expansion would proceed, with voters expected to elect new supervisors beginning in 2032, according to county officials.

The Board of Supervisors has already moved forward with the creation of an ethics commission, but passage of Measure G would codify its existence in the county Charter.

While the proposal has garnered support from various groups and elected officials, there have been some concerns expressed, including the additional costs anticipated with an expansion of the board. Horvath has insisted that the changes in Measure G would not create any additional costs to taxpayers or cuts to services or programs.

Some critics worry creating an elected county executive may politicize the position.
