In Riviera Beach, city council has set aside $1.5 million for advance work on a sprawling municipal redevelopment plan that will include a new City Hall and could cost as much as $300 million. The money will be used for consultants, legal advisers and to develop a competitive bidding process for those hoping to win city contracts related to the project. Some of that work will be carried out by a master developer who will put together plans for the project. The council vote was the latest in an initiative city leaders have dubbed "Reimagine Riviera Beach."
