The Miami Herald reports that a referendum will be needed if David Beckham and his investors want to build their MLS soccer stadium on the boat slip next to the American Airlines Arena. The boat slip would need to be filled in and could take up space in the almost finished Museum Park. 

The county owned property on the Port of Miami would not require a referendum, but could seek voter approval.

The earliest votes could take place is August, but a November ballot seems to be the more likely scenario.
