09:41 PM EST Share Downtown Investment Authority and city officials will select a design by July for the site now called Riverfront Plaza. Three national design firms pitched their visions June 24 for a city park at the former Jacksonville Landing on the St. Johns River Downtown. The design teams, Agency Landscape + Planning LLC, Olin Partnership Ltd. and Perkins & Will Inc., pitched plans at the Main Public Library Downtown to a panel of city officials and local business and nonprofit leaders. “Our desire is to become a city of vision and reality instead of a city of renderings,” said Haskell landscape architect Chris Flagg during public comment.
