900 Biscayne Bay's condo association has officially filed a formal appeal to Miami's Planning, Zoning & Appeals Board in opposition to Miami Worldcenter's high street retail proposal. World center already has approved plans for an enclosed mall in addition the high street retail plan, which would remain valid should either the Planning, Zoning & Appeals Board or the Miami City Commission revoke the open-air concept. Michael Gongora is representing the association in the appeal. Construction has already begun on various phases of Miami Worldcenter including Block G which will feature Seventh Street Apartments & retail.
