Another big change to Miami Beach-slash-Miami’s skyline is getting ready to occur on Watson Island if the stars align for Flagstone Development. Island Gardens, a project that died with the economy in 2008, is back in the works. Not long after a lavish fete and preliminary sales, the mega-yacht marina quietly went away four years ago. Now it’s back on with a mixed use building that combines high-rise condos, hotels by Shangri-La and Westin and of course, the marina that is finally going to have deep enough waters for billionaires to bring their super yachts of up to 400 feet.. Watson Island is also home to the Miami Children’s Museum and Jungle Island, which has struggled in recent years due in part to the Port of Miami Tunnel project construction. That should be all finished up if the projects proceeds as predicted and is completed by 2019.
