The City of Miami is working with CBRE to sell its administrative headquarters located next to the Miami River and I-95, according to the Miami Herald.  The building sits on 2 acres of land and is over 320,000 square feet which has potential for a "megaproject scale" as Curbed Miami describes.

Earlier this year, a 2.24 acre lot just North of the Miami Riverside Center site sold for $21 million by FP&L to Miami Bridge Lot Ventures. On the other side of the river is the Miami River project by Chetrit Group, which will be a megaproject with hotels, offices, retail and residential units that recently started demolition on the site. 

Any deal on the Miami Riverside Center for a land swap to build a new administrative center would require voter referendum.
