"Now, we have to look at what's under the site," Wolff said. "Tenants (the Raiders and Warriors) share this site and we have to talk to them. We have to address the parking issue.
"There are difficulties with any venue of this nature," he added. "You will find that to be the case in any place. Elsewhere in the country, you will run into issues such as these, too."
In addition, the city got some news on how far the plan is progressing:
Last week, De La Fuente received an indication -- via a letter from Wolff -- that some advancement already has been made.
"It was official notice to the (Coliseum Authority) that he has engaged an architectural firm in Los Angeles to start exploring the possibility of building a stadium in Oakland," De La Fuente said. "They're taking the lead on it, and I see that as a reason to be optimistic."
If they focus on the existing south lot, a ballpark could remove 4,000 spaces. Someone would have to build a lot of garage parking to make up for the loss. Those parking garages could cost $6-8 million to build, plus there's the fact that garages don't make for quality tailgating.
