Article content The National Capital Commission board of directors on Thursday approved the final concept plan for LeBreton Flats and learned the identities of three development teams competing to build the first part of the modern-day redevelopment of the key federal site. The concept plan sets the development areas and parkland that will be established over 35 years on the 29-hectare land. The mixed-use plan estimates about 7,500 people will live in homes at the redeveloped LeBreton Flats at full build-out, with 12.5 hectares of land dedicated to park space. Twenty-five per cent of homes will be considered affordable. We apologize, but this video has failed to load.
