ST. PAUL — The Prairie Island Indian Community and Capital City Properties — the development wing of the St. Paul Port Authority — have partnered on a housing-and-hotel proposal for the site of the RiverCentre parking ramp on St. Paul’s Kellogg Boulevard.

The city of St. Paul recently issued a request for proposals asking developers to present general concepts for the vacant space above the downtown convention center parking ramp, including the possible reconstruction of the ramp itself and connections to the long-awaited “river balcony” promenade overlooking the Mississippi River.

Six developers or development teams submitted concept plans, of which three had chosen to make their renderings public by late December. A fourth proposal from the Prairie Island Indian Community and Capital City Properties, made public Monday, Jan. 6, includes 300 hotel rooms and 125 apartments. The project would include a main entrance on Kellogg Boulevard and a restaurant, meeting spaces and a shared amenity floor with a pool and fitness area.

Ideas presented by the development community have run the gamut from a movie theater to office towers.
