1.11 LeBreton Flats
(Reference may be made to the report entitled "The LeBreton Flats Plan incorporating Official Plan Amendments" prepared by the National Capital Commission, January 1997. This report contains extensive background information concerning LeBreton Flats.)
1.11.1 Vision
Unique Site
LeBreton Flats is a unique site, critical to the future of the heart of the Nation's Capital and the Central Area of the City of Ottawa. LeBreton Flats has a destiny, other than as idle lands, and has the potential to support a vibrant community once again.
People-Place
The Vision is to make LeBreton Flats a people-place for the next century; to challenge the developers and decision makers of the future to create an urbane community within the Ottawa downtown where people can live, work, socialize and play. This community will be one of mixed uses, surrounded by open spaces. It will consist of compact neighbourhoods, linked together and to the wider open space network by pathways and pedestrian-friendly streets. The entire area will be supported by highly accessible public transit, to reduce reliance on the automobile.
Mixed Uses
LeBreton Flats will mean residential intensification in the Central Area and the introduction of new community-based employment opportunities. Mixed use will be a priority, in achieving a balance of jobs and housing and more efficient use of valuable urban land and infrastructure. Housing types, sizes and costs will respond to current and upcoming demographic shifts, and offer new opportunities for high quality design at medium to high densities within the Central Area. It will "reclaim" an orphaned site, through ensuring that remediation is undertaken as the site is developed.
National Capital Role
The role of Ottawa as the National Capital will be enhanced by the future LeBreton Flats. One of the last waterfront pieces of real estate in the downtown area will be retained in public hands as open space, with an emphasis on public access, and cultural and office uses of national and capital significance. A "LeBreton Common" will be provided as a major gathering place and stage for events, filling a critical gap in the current system of programmable open spaces in the Capital.
Blueprint for 21st Century
The LeBreton Flats plan represents a blueprint for the 21st century, which has the ability to satisfy many objectives through its diversity, balance and orientation.
1.11.2 Objectives
- To provide an extension to the Central Area, with a diverse range of uses and activities, where people can live, work, socialize and play.
- To create an opportunity to increase the National Capital presence in the Central Area, with development that will attract visitors to Ottawa.
- To promote compact development and encourage the efficient use of land in proximity to the LeBreton Flats transitway station.
- To provide an opportunity to substantially increase the number of dwelling units in the Central Area, with a range of housing options.
- To promote increased employment opportunities in the Central Area.
- To promote linkages with the adjacent areas and encourage the use of LeBreton Flats by the existing community.
- To ensure that development is compatible with the adjacent areas.
- To enhance the unique attributes of the site, such as the riverfront and the aqueduct.
- To encourage public use and accessibility of the Greenway System.
- To protect and integrate the designated heritage features such as the aqueduct, its bridges and the Pumping Station, in a sensitive manner.
- To ensure that infrastructure improvements are identified and undertaken.
- To ensure that the area meets the applicable soil and groundwater remediation standards.
- To ensure that development proceeds in an orderly and efficient manner.
