S1- Barrhaven South - West of Greenbank - Future Neighbourhood

NOTICE OF COMPLETION

City of Ottawa – Municipal Class Environmental Assessment (EA) Master Plan for S1 Future Neighbourhood (Barrhaven South Urban Expansion Area) Official Plan Amendment

RECOMMENDED MASTER PLAN

The Barrhaven South Urban Expansion Area integrated master planning and engineering process for the S1 Future Neighbourhood followed the Environmental Assessment (EA) Master Plan Approach 2 integrated with Official Plan Amendments under the Planning Act.

The City of Ottawa recommends the following Master Plan studies to facilitate development of a new residential suburban community including environmental protection lands, park uses, new roads, and stormwater management facilities on the subject lands. The following Master Plan studies identify the recommended transportation, water, sanitary, and stormwater infrastructure projects required to service the new community to a Schedule B level of detail:

• Addendum to the Barrhaven South Urban Expansion Area Master Servicing Study
• Addendum to the Barrhaven South Urban Expansion Area Community Transportation Plan
• Barrhaven South Urban Expansion Area Phase Three Environmental Impact Study: Addendum to Barrhaven South Urban Expansion Area Environmental Management Plan
• Updated Barrhaven South Urban Expansion Area Community Design Plan

The Master Plan studies are available at the following locations:

• City of Ottawa Wednesday, July 15, 2026 @ 10:00 AM, Andrew S. Haydon Hall, 110 Laurier Avenue West, and by electronic participation: S-1 Barrhaven South Future Neighbourhood - City Council - July 15, 2026
• City of Ottawa Engage Ottawa project website: S1- Barrhaven South - West of Greenbank - Future Neighbourhood | Engage Ottawa
• City of Ottawa Development Applications website (Application # D01-01-24-0002): Application Details - Development Applications Search

The Master Plan studies were circulated for review and comment by members of the public and technical agencies through the Official Plan Amendment circulation process between April 20, 2026 and May 21, 2026. The Master Plan studies were approved by City of Ottawa Planning and Housing Committee on July 8, 2026 and were approved by Ottawa City Council on July 15, 2026. The approval of the Official Plan Amendment to remove the Future Neighbourhood Overlay and add area-specific policies to the Official Plan, along with the accompanying Community Design Plan update and supporting Master Plan studies, establishes the basis for subsequent draft plan of subdivision, zoning, and infrastructure approvals.

Comments are maintained for reference throughout the project under the Municipal Freedom of Information and Protection of Privacy Act (MFIPPA) and the Environmental Assessment Act.

The Guiding Document: Draft Community Design Plan (CDP) The Community Design Plan (CDP) serves as the primary blueprint for developing the S1 Future Neighbourhood (Phase 3 of the Barrhaven South Urban Expansion Area). The core vision of the CDP is to plan for a livable, "15-minute neighborhood" where residents can easily access daily needs like parks, schools, the library, and commercial areas. To achieve this, the CDP outlines a comprehensive land-use plan that integrates low, medium, and higher density, ground-oriented housing alongside green spaces, transportation corridors, and commercial-industrial land uses.

To support the vision for Barrhaven South Urban Expansion Area the CDP is guided by four supporting technical studies:

1. Draft Environmental Impact Study (EIS) The EIS evaluates the natural environment on the S1 site to ensure local ecosystems are protected during and after development. It confirms the presence of important habitats such as significant woodlands. The study recommends the retention of the majority of these woodlands. It also outlines mitigation measures, such as installing protective fencing, restricting tree clearing during wildlife breeding seasons, and implementing tree planting plans to mitigate the partial loss of significant woodlands.

2. Draft Master Servicing Study (MSS) The MSS details how the new neighborhood will connect to the City of Ottawa’s existing water, wastewater, and stormwater infrastructure. It confirms that the City's current systems have the capacity to support the new homes. A major focus of the MSS is stormwater management; it plans for a new stormwater pond and underground systems to safely handle rainfall runoff, prevent flooding, and protect local groundwater sources. A particular feature of Barrhaven South Urban Expansion Area is the implementation of a groundwater recharge program so that stormwater from local streets is infiltrated into the deeper regional aquifer.

3. Draft Transportation Study This study ensures that residents can move safely and efficiently within and beyond the neighborhood using all transportation modes. It plans for the extension of existing collector and local streets and emphasizes the design of "complete streets". The plan aims to keep vehicle speeds low as well as providing dedicated pathways for walking and cycling and other active transportation modes. The study supports public transit by integrating future Bus Rapid Transit (BRT) routes on new Greenbank and a Park and Ride facility into the community plan.

4. Draft Community Energy Plan (CEP) The CEP focuses on identifying voluntary strategies that make the neighbourhood more sustainable, energy-efficient, and resilient to climate change. It outlines practical strategies to lower greenhouse gas emissions across the community. These strategies include encouraging the building of homes that exceed standard building code energy requirements, utilizing smart home technologies (like heat pumps), diverting construction waste, and planting of large-canopy native trees on the site’s well drained soils to cool the neighbourhood and reduce the urban heat island effect.

The draft revised Barrhaven South Urban Expansion Area Community Design Plan (CDP), along with supporting technical studies, is now available for public and agency review and comment.

The CDP and supporting Environmental Assessment studies have been prepared in accordance with the City’s Official Plan and related master plan requirements for new community planning in future neighbourhoods. This update to the CDP incorporates the 45-hectare S-1 Future Neighbourhood area.

Comments will be accepted until May 21, 2026.

All feedback will be reviewed and considered as the plan is refined. Staff anticipate bringing the final Community Design Plan forward to Committee in Summer 2026 for consideration.

We wish to thank residents for participating in the second public open house which was held on February 12, 2025 at the Minto Recreation Complex, 3500 Cambrian Road, in Barrhaven.

The purpose of the event was to present the study process, including:

• the Environmental Assessment Master Plan process
• the existing environmental, infrastructure, transportation, and planning conditions
• the problems and opportunities to be addressed
