MIAMI -- City and county officials along with the Marlins and stadium owner Wayne Huizenga are considering, among other things, the possibility of putting a domed-roof on the existing stadium in an attempt to keep the team here.

Local 10 has learned that Marlins President David Samson asked the Miami and Miami-Dade County managers last Friday to make up a $30 million stadium funding deficit with still more tourist tax dollars.

The proposal came in the wake of failure by the state legislature to fill a $30-million funding gap for a new stadium and the rejection of a team request for more tourist tax dollars.

With a firm "no" from County Manager George Burgess and Miami City Manager Joe Arriola, and no additional money available from the Marlins, Local 10 has now learned that another proposal has resurfaced from Dolphins Stadium owner Wayne Huizenga.

Local 10's sources say the deal calls for the $138 million in tourist tax money already committed for a new stadium to be spent for a roof on Dolphins Stadium; the Marlins would play in the stadium rent free; and for the first time, the Marlins would get revenue from concessions and from sky boxes and club seats.

The county would also get some kind of ownership or management contract with the stadium for Marlins baseball. Huizenga would still control all revenues from the Dolphins and would be guaranteed a consistent fan base for his proposed $300-million "super site" entertainment complex, to be built adjacent to the stadium.

At this point, there is still no real commitment of any kind.

For the record, even though it seems unlikely, Burgess told Local 10 he is still trying to put together a deal for a stadium next to the Orange Bowl.

A new deal at Dolphins Stadium is more likely to succeed, according to Local 10's Michael Putney, who has closely followed the developments. While the Marlins owners have always insisted they want their own stadium, Putney says they might have to settle for a better deal at the one where they now play.

Major league baseball has given all the parties an ultimatum that a deal has to be done by June 9.
