Initiated in 1989, the tripartite planning process brought together the National Capital Commission, the City of Ottawa and the Regional Municipality of Ottawa-Carleton. Their task was to chart a future for one of the most important sites in the Capital - LeBreton Flats. This tripartite process involved the public from the outset, and focused on finding common ground amongst a myriad of competing priorities and interests. The resultant plan establishes a blueprint for a new LeBreton Flats community. Driving the planning was an unwavering conviction shared by all that the time had come to bring life and activity back to the Flats. The success of this tripartite process is not only significant because a plan for LeBreton Flats was produced. Many other benefits result. Three levels of government joined forces and worked together, bringing a proposal forward for one of the most challenging pieces of land in the Capital. The major land use decisions for LeBreton Flats, from this point forward,lie with municipal governments. The NCC and the federal government will be instrumental in bringing approved plans to fruition. Recent decisions of the three governments provided the basis for the Official Plan Amendments now being presented for consideration. In'1,996, Councils of the City of Ottawa and the Region, and the Commission of the NCC approved a I l land agreement which commits the three parties to a process of planning approvals and future land transactions that will lay the groundwork for the redevelopment of LeBreton Flats. Through the approval of this land agreement, it was decided that the NCC would submit applications, based on the tripartite concept plan for LeBreton Flats, for Amendments to the Official Plans of the City of Ottawa and the Region. The National Capital Commission proudly presents this document in support of the Official Plan Amendment applications. 1.0 BACKGROUND 1.1 History of LeBreton Flats LeBreton Flats was an important community in the history of the City of Ottawa. The area was first settled in the early 1800s and, by the 1850s,lumber companies run by lumber barons such as Henry Bronson, Ezra Butler Eddy and |ohn R. Booth had established themselves on LeBreton Flats. The late 1800s saw the beginning of industrial development on the site which was to shape the Flats until the 1960s. The Canadian Pacific Railway freight terminal, the Eddy paper plant, Hydro power facilities and the City's first waterworks building were located on LeBreton Flats and the adjacent islands. On April 26,1900, the "Great Fire", which destroyed much of Ottawa and Hull severely damaged LeBreton Flats. The community, both residential and industrial, rebuilt. The railway marshalling yards were also constmcted at this time. In'1,962, the Federal Government acquired and cleared the buildings on LeBreton Flats to accommodate federal office buildings and the Ottawa River Parkway. However, due to federal government poliry decisions, the federal offices were eventually located elsewhere in the core of the City of Ottawa and to Hull. A number of planning efforts were undertaken in the seventies and eighties to determine the future vocation for the Flats; however, none came to full fruition. For example, during the mid-seventies, Canada Mortgage and Housing Corporation proposed to construct housing. However, only a demonstration project south of Scott Street was constructed, while plans for north of Scott Street did not materialize.
