Riverfront Park is an urban infill planned community that currently includes 1,859 rental and for-sale housing units in 14 buildings, 49,000 square feet of retail and restaurant space, a museum, and three parks on a 23-acre site adjacent to downtown Denver. The project was initiated by the city of Denver on former railroad land, and involved a firm that assembled and rezoned the land and a second partnership of firms that undertook much of the development and construction. The project is arranged in a linear fashion between railroad tracks on one side and a 19-acre park developed by the city on the other, and is connected to the downtown by an iconic pedestrian bridge that spans the railroad tracks.
