The Miami Dolphins are hopeful the Miami-Dade County Commission will approve a May 14 date for a referendum on the $400 million rehabilitation of their stadium, time enough to get South Florida in play for Super Bowl 50, a Dolphins spokesman said Saturday.

Spokesman Ric Katz said the language of the proposed referendum has yet to be decided, and ultimately the commission decides the date.

But, he said, “we’d be very happy with” May 14 because “that gives us a week to communicate to the NFL before they make the important decision of Super Bowl 50.”

NFL owners are slated to meet on May 22 to pick the site of the 2016 Super Bowl — seen as a tourist revenue prize for whichever host city gets the 50th anniversary contest.

Mayor Carlos Gimenez met Friday with Dolphins owner Stephen Ross and CEO Mike Dee to discuss the proposed stadium rehabilitation.

From the mayor’s side, there has been no agreement on a date and Gimenez does not plan to bring the proposed May 14 referendum to the commission at this time, said spokeswoman Suzy Trutie.
