OAKLAND — In what could be the first step toward keeping the Raiders in Oakland long term, Mayor Libby Schaaf said Wednesday she is open to leasing Coliseum land to the team at a “favorable” price and sacrificing development opportunities to preserve parking spaces for tailgaters.

The mayor’s statements, made one day after the NFL rejected the Raiders’ bid to move to Los Angeles, marked a sharp departure from Oakland’s Coliseum City vision of packing the 120-acre East Oakland site with new stadiums, office buildings, homes and shops.

Still, it’s unclear whether the new approach is viable or whether Raiders owner Mark Davis, who has been increasingly critical of the mayor, will consider it.

Schaaf is still refusing to help pay for a stadium or give Davis full control of the Coliseum site, which she fears could drive away the Oakland A’s, who are also seeking a new home. And scaling back development could limit available funds for a new stadium.

On Tuesday night, Davis refused to commit to playing in Oakland next season, fueling speculation that he could be eyeing a move to San Antonio.

Oakland’s original Coliseum City plan was a non-starter for the Raiders in part because it required building multilevel parking garages that would have been off-limits to tailgaters, while potentially snarling traffic after games.

While Schaaf still envisions some development on the site, primarily concentrated near the Coliseum BART station, she said the city’s latest plan would retain 8,000 of the roughly 9,500 existing surface parking spaces surrounding the stadium.

“We’re asking the Raiders to give us the time and attention to show that this can be done,” she said. “We never were able to get to the level of detail where they could see how we can leave room for development and still have the parking and tailgating they want.”

The Raiders will have extra incentive to look closely at the city’s new approach. As part of a compromise that will bring the St. Louis Rams back to Los Angeles next season, the NFL is offering to boost its financial support for a new stadium in Oakland from $200 million to $300 million. That is roughly one-third of the estimated $900 million price tag. The Raiders had previously pledged $300 million themselves.

Davis had repeatedly said he wanted to stay in Oakland even as he worked on a bid to move south. His sudden ambivalence toward the city comes amid a dispute over whether Schaaf reneged on her predecessor’s offer to give the Raiders the 120-acre Coliseum site and additional land free of charge.

“(Schaaf) knows what it’s going to take to get something done,” Davis said Tuesday, referring to his demand that the team have full control over the site.

Schaaf said she planned to call Davis on Wednesday in hopes of improving relations and making sure that Davis isn’t trying to leave Oakland right away.

“Up until the last few hours, Mark has said consistently that his preference is Oakland,” Schaaf said. “I intend to do everything I can to rekindle that feeling.”

Even if Davis wants to leave, he has fewer options, especially after ruling out a move to St. Louis, which just lost the Rams to Inglewood despite offering a $400 million stadium subsidy.

The NFL granted the San Diego Chargers the option to join the Rams in Los Angeles. If the Chargers agree to move, as expected, that would free up San Diego, but the Raiders might not fare well in a city where most fans grew up rooting against them.

Davis has mentioned San Antonio as a possible landing spot, and the city’s former mayor, Henry Cisneros, told the San Antonio Business Journal on Wednesday that bringing in the team would be “so huge that we must give it our best shot.”

But former team president Amy Trask said a third team in Texas could face opposition from Dallas Cowboys owner Jerry Jones and Houston Texans owner Bob McNair — two of the most powerful men in the league.

“I can’t foresee (them) or the league wanting a team in San Antonio,” she said.

Funding an NFL stadium in Oakland remains a difficult proposition even with additional league financial help. Oakland wants to join the ranks of New York, Santa Clara and now Los Angeles in avoiding direct stadium subsides. But it lacks the private wealth that helps to get those projects funded.

“The 49ers market is meaningfully more affluent than the Raiders demographic,” said stadium consultant Marc Ganis, who worked on bringing the Raiders back to Oakland in 1995.

Development rights have been seen as a way to bridge the funding shortfall, but even city leaders questioned whether the highly ambitious Coliseum City project was feasible.

Schaaf is now offering the Raiders half of the 120-acre Coliseum complex to build a stadium as well as development rights to roughly nine acres the city is trying to assemble adjacent to the Coliseum BART station for a hotel and office project.

The city hasn’t given estimates as to how much those rights would be worth, and several real estate analysts doubted it would take a serious chunk out of the now $300 million shortfall.

Davis, who did not return phone calls Wednesday, said last month that he is open to selling a portion of the team to raise money for the project but that he needs full control of the land to make it attractive for a developer.

Davis insists that Jean Quan made him such an offer, but the former mayor said the deal was contingent on the Raiders sacrificing surface parking spaces and surrounding the stadium with a mini-downtown that would have created thousands of jobs and boosted tax revenues.

“The problem with Mark (Davis) is that he always takes the elements that he wants as opposed to the other commitments,” she said.
