NEW ORLEANS (AP) — The city of New Orleans now has two proposals to renovate an empty office building that occupies valuable riverside land and a third proposal — backed by the city’s tourism establishment — to replace it with a sleek new tower to mark the city’s approaching tricentennial in 2018.

Each of the two proposals for remodeling the old World Trade Center building includes a luxury hotel and residential complex. Both would re-open a revolving rooftop restaurant and lounge that once was a popular city gathering spot.
