Arthur Falcone's Miami World Center has submitted their plans and applied for a warrant for their "High Street Retail" with Miami's Planning & Zoning Department as part of Downtown Miami's multi-billion dollar mega mixed-use residential and retail project Paramount Miami World Center. It will ultimately be the second-largest mixed-use urban development in the United States and largest in Florida. In 2015 the developers had received a warrant for an indoor mall, but after adjusting plans earlier this year to an outdoor mall concept, they have submitted the revisions. Although the new plans were reviewed and approved by the Urban Design Review Board, the decision on the new warrant cannot be issued prior to October 6. Construction has started on Paramount residential skyscraper as the first phase of the project and will finish as a 1.1 million SF urban mega-center over 27-acres.
