Pathway rehabilitation tour

This one is an OAW exclusive.

Let’s take a walk down one of Ottawa’s busiest pathways, running along the picturesque Parliament hill and the Ottawa River. We’ll focus on the section that follows along the base of the escarpment abutting the north edge of Parliament Hill, the Supreme Court of Canada, and continues west past the Library and Archives Canada building.

This segment was battered heavily by the 2017 floods, and yet again in 2019. The former washed away large sections of the pathway making them impassible. Some areas were fully submerged by high flood waters.

Once the flood waters receded, the rehabilitation works began, starting with the full assessment of the damages. It was important to come up with a solution that would stand the increasingly violent and frequent weather events.

A team of specialist developed a new solution based on multiple presidents, focusing on flood resiliency and green infrastructure. The new shoreline features a robust rip-rap slope designed to resist flooding, the existing currents, and ice movements. Elevation changes

have been designed to help channel water and expose a breakwater structure as flooding recedes. Finally, a new planting design provides both an aesthetic quality and creates a sustainable erosion resistant root system. All of this elements work as a single system.

This project was completed in fall of 2018, and since then was tested extensively, much earlier than expected in the spring of 2019.

The pathway resisted the flooding with only minor surface damage.
