The Florida Marlins are considering a revised proposal for a $525 million ballpark on the site of the Orange Bowl that includes both increased long-term county costs and a large, upfront contribution from the team. According to details of the revised proposal, the Marlins would pay $155 million upfront. Miami-Dade County would pay $199 million in tourist tax dollars and $50 million from a general obligation bond, according to a county memo that was posted on the county commission's Web site. "It does take more of the risk off of the government, so that's a good thing," Commissioner Jose Diaz said. The county commission is scheduled to meet Tuesday. Several other commissioners did not return phone messages and e-mails Wednesday, and Marlins' President David Samson denied comment. The team has said it needs a new ballpark to survive in South Florida.
