The Los Angeles Memorial Coliseum Commission Wednesday approved a series of reforms to make governance of the historic facility more streamlined and accountable.

The Joint Powers Agreement, the Coliseum’s governing document, would be amended to cut the size of the commission under the proposal passed by the commission. The revised structure was created to meet new needs that would follow a pending revised lease agreement with the University of Southern California.

The revised agreement would cut the size of the nine-member commission to three members, and would contract the commission’s daily management functions to Los Angeles County.

“This is the kind of nimble, stable and accountable governing structure the new Coliseum Commission will need in the 21st century,” said Supervisor Mark Ridley-Thomas, who chaired a commission task force to revise the agreement. “When the University of Southern California takes a greater role in managing the Coliseum and Sports Arena, a smaller commission, combined with professional administrators from Los Angeles County, will better serve the commission’s more focused mission,” Ridley-Thomas said.
