The Powerhouse Arts District is a historic warehouse district in Downtown Jersey City, New Jersey, United States, which takes its name from the unused generating station Hudson and Manhattan Railroad Powerhouse currently undergoing an extensive stabilization effort. Since the millennium the section is called WALDO, an acronym for Work And Live District Overlay, an 11 block section of historic warehouses, some of which have been redeveloped, and is still used on maps and in local parlance.
