After a nearly five-year delay, a $350 million mixed-use development in Jersey City is slated to break ground in the next few months. The Real Deal reports that the Jersey City Municipal Council and Planning Board approved plans back in December. Gwathmey Siegel Kaufman + Associates Architects will design the two 50-story towers at 70 and 90 Columbus Street. The 1.2 million-square-foot development, a joint venture by Ironstate Development and Panepinto Properties, will consist of a 150-room hotel and approximately 1,000 rental apartments in addition to retail space.
