With the county preparing to sell its share of the Coliseum, the complex's other owner is the city of Oakland.
Mayor Libby Schaaf told the supervisors before their vote that they shouldn't approve the sale to the team without requiring the A's to commit to community benefits such as affordable housing, good union jobs and healthy environmental standards.
But Supervisor Scott Haggerty said the county can't do anything about those issues because it doesn’t have jurisdiction over the Coliseum property.
"That discussion would be better in the Oakland City Council's chambers," Haggerty said.
Oakland A's President Dave Kaval said after the board's vote that he hopes the A's can finalize the deal with the county soon.
"We're looking forward to working with the city" on ways to develop the Coliseum site, Kaval said, adding that the A's also would be interested in buying the city's share if it wants to sell it.
The A’s also made some progress in Sacramento this week on legislation to support the Howard Terminal ballpark. A bill that would allow the development along the Oakland Estuary passed one Assembly committee on Monday and is scheduled to be heard by a second committee next week.
