The NCC has embarked on a process to create a renewed vision for a dynamic Capital destination and a complete community where people can live, work and play. Learn more about the project background and process here.

Preliminary Master Concept Plan

On January 23, 2020, the NCC’s Board of Directors approved the preliminary Master Concept Plan for LeBreton Flats.

Based on public feedback, this plan envisions a place that is pedestrian- and cyclist-friendly, surrounded by lively and active parks and plazas, including the dynamic Aqueduct District, the Ottawa riverfront and a large destination park. A future diverse residential community will be supported by retail and employment opportunities, capitalizing on direct access to two LRT stations.

This preliminary Master Concept Plan identifies the following:

  • the overall structure of the community
  • parks and public spaces
  • locations for major anchor uses
  • pathway, sidewalk and roadway networks
  • land uses
  • building heights and massing
  • urban design guidelines

LeBreton Flats will comprise four districts, each with unique features.

The implementation planning phase of the Building LeBreton project, in the first half of 2020, will determine the order in which the various parcels of land will be developed, and parks and public spaces created.

Aqueduct District

The heart of LeBreton Flats — a vibrant cultural hub and entertainment district spilling out onto public space along the two historic aqueducts.

Flats District

A predominantly residential community defined by intimate, pedestrian-oriented streets and a variety of housing types.

Albert District

A mixed-use neighbourhood anchored by the future Library and Archives Canada and Ottawa Public Library joint facility to the east and a potential event centre or major facility to the west, the Albert District provides space for homes and offices, as well as shops and services along Albert Street.

Parks District

A series of park spaces combining the community’s industrial heritage with its defining natural elements, creating a unique experience that will draw visitors from near and far to the western end of the community.

Master Concept Plan Strategies

The districts are outlined through three strategies within the preliminary Master Concept Plan.

LeBreton Flats will be a thriving hub with diverse housing options, offices, shops, restaurants, services and cultural offerings. The land uses proposed throughout LeBreton Flats help cultivate a dynamic, mixed-use community, while remaining flexible to adapt to changing needs and opportunities

Parks and the public realm are the heart of what will make LeBreton Flats unique. Water forms the spine of the Parks and Public Realm Strategy, connecting LeBreton Flats from east to west through its heart at the Aqueduct District. All public realm considerations at LeBreton Flats contribute in some way to celebrating and connecting people to the Ottawa River and Nepean Inlet, as well as the historic waterworks complex and aqueducts. They also incorporate elements that recognize the area’s overlapping roles as a destination, as part of the nation’s capital and as a home for Ottawans.

The Master Concept Plan celebrates human-powered mobility throughout its design, incorporating woonerf-style shared-street designs on all internal roads. By intentionally building LeBreton as a universally accessible, transit-oriented, active-mode-priority neighbourhood, the community’s design enables a fully urban lifestyle that provides for the daily needs of residents without requiring automobile travel.

In addition to the first three strategies in the preliminary Master Concept Plan, work is under way to add five more strategies to the final Master Concept Plan by the fall of 2020:

  1. Infrastructure Strategy
  2. Sustainability Strategy
  3. Indigenous Connections
  4. Culture and Heritage Strategy
  5. Affordability Strategy

Public Consultation Results

The LeBreton Flats Master Concept Plan is informed by feedback from two public consultations.

    More than 2,000 people participated in each of the public consultations. Overall, public feedback on the draft Master Concept Plan and the ideas presented in November/December 2019 were positive and validated the direction of the NCC’s work. Highlights of key changes to the Master Concept Plan arising from public feedback include the following:

    • The number of districts has been simplified to four.
    • Identification of smaller neighbourhood parks and opportunities for privately owned public spaces (POPS) have been improved.
    • Tree cover requirements have been included for parks, streets and the public realm.
    • All-season programming of parks, streets and the public realm is emphasized.
    • Pathways were separated to accommodate both pedestrians and faster users (cyclists, in-line skaters).
    • Tower stepbacks were increased to emphasize mid-rise building form.
    • Allowances have been included for larger retail spaces for desirable uses in key locations (e.g. grocery store).
    • Locations for institutional uses have been identified.

    While this input assisted the NCC in refining the plan, a considerable proportion of the feedback also provides useful direction and ideas for the implementation planning work that the NCC will undertake through the first half of 2020. Comments related to sustainability measures, housing types and affordability, Indigenous presence and participation, art, heritage and cultural elements, and more will all provide useful input into the implementation planning process.
