Public Notice
Construction of Berms at Connaught Park: Public Comments Invited

July 13th, 2020 - The National Capital Commission must determine, as lead authority, whether the proposed construction of berms at Connaught Park, located on lands owned by the National Capital Commission in Ottawa, Ontario is likely to cause significant adverse environmental effects. 

To help inform this decision, the National Capital Commission is inviting comments from the public on the project and its potential effects on the environment. All comments received will be considered public. For more information individuals should consult the Registry website.

Written comments must be submitted by August 13th 2020, referencing project name and registry number.

The Proposed Project 

 

The NCC has received a Federal Land Use Approval application from the City of Ottawa for the construction of berms - raised landscape features of compacted soil - at Connaught Park on NCC property. These berms would be created using soil excavated in the Connaught Park area as part of the Stage 2 Ottawa Light Rail Transit (OLRT) Confederation Line extension. Current plans indicate that up to 40,000 m3 of excavated soil will be used to construct the berms. Only clean soil that meets Ontario Regulation 153 Table 1 criteria will be used, as verified by a qualified professional prior to its placement on NCC property.

The original soil management plan, submitted to and approved by the NCC as part of the overall OLRT Stage 2 construction, was to haul this excess 40,000 m3 of material to landfill. Instead, the City of Ottawa proposes to beneficially reuse the soil in landscaping that will incorporate the strategic location of berms to result in improved drainage in Connaught Park and provide both a visual and noise buffer between the nearby residential area and OLRT infrastructure. The reuse of clean soil in this manner preserves the capacity of local landfills and reduces truck hauling and its associated greenhouse gas emissions, consistent with the objectives of the NCC's Sustainable Development Strategy.

The size and location of the berms have been designed to preserve existing trees to the greatest extent possible. Current plans require the removal of two trees between 10cm and 25cm diameter at breast height (DBH) and two trees greater than 25cm DBH. The landscape plan will incorporate planting over 200 new trees, exceeding the NCC's typical 2:1 compensation ratio. Also included in the plan are invasive species removal and seeding with native mixes beneficial to wildlife and pollinators. Revegetation will progress as the berms are completed. Tree planting will occur in stages as weather permits to ensure optimal survivability of a diverse selection of species.

Construction of the berms is expected to begin in August and continue through November 2020.
