OAKLAND — Oakland on Wednesday began negotiating with the A’s to sell the team its half-ownership share of the Oakland Coliseum weeks after the team proposed to buy it for $85 million.

The city also plans to drop its lawsuit against Alameda County — which has the other half-ownership — by next Thursday, Nov. 14, City Councilmember Larry Reid told the Bay Area News Group. The A’s earlier also offered to buy the county’s share of the Coliseum, and sale negotiations were taking place when the city stepped in and sued to block the sale.

The city’s bargaining group “had a successful meeting” with A’s management on Wednesday afternoon, Reid said without going into further detail. He said council members will be updated on the negotiations during closed session at their next meeting.

The City Council unanimously voted Tuesday to give the city attorney’s office the OK to withdraw the lawsuit, but only after certain “issues” — Reid wouldn’t elaborate — were worked out. Reid said that didn’t happen Wednesday, but the lawsuit will likely be scrapped before the next scheduled court hearing Nov. 14.

The A’s won’t buy the city’s share unless the lawsuit is dropped.

The baseball team wants to convert the complex to a mixed-use development to help it finance the construction of a 35,000-seat waterfront ballpark along the estuary near Jack London Square.

In its offer to the city, the A’s agreed to build affordable housing at the Coliseum property, use local labor and provide other yet-to-be-determined community benefits.

A’s president Dave Kaval told the Bay Area News Group in October that the offer includes an option for Oakland to lease the land to the team as a “joint venture” rather than selling it.

Oakland’s lawsuit against the county was meant to block the sale of the county’s ownership share to the A’s, alleging the sale would be illegal under the state’s Surplus Land Act, which requires publicly owned land that is up for sale to first be offered for affordable housing, parks or open space.

City officials had sought to buy out the county’s ownership itself — they wanted Oakland to have greater say in the future of the site and noted it would make more sense for the city to be the sole negotiator with the A’s since the Coliseum is in Oakland.
