Reusing Fill to Bring Nature Back to the Waterfront

November 15, 2017 (MISSISSAUGA) – After one year of construction, the transformation on the Mississauga waterfront is well on its way. Credit Valley Conservation, the Region of Peel and Toronto and Region Conservation Authority are creating a beautiful 26 hectare conservation area in the Lakeview community. They are able to do this by responsibly reusing construction rubble and fill. They are treating fill as a resource so the local community can benefit.

A large portion of the fill is generated from Region of Peel capital works projects. There is often excess soil from water and wastewater projects that must be disposed. Contractors often have to travel long distances to dispose of fill.

“That fill can now be sustainably reused locally,” said Andrew Farr, General Manager, Water and Wastewater for the Region of Peel. “Having a local destination for fill keeps thousands of trucks from making that long journey each year, which means a significant reduction in greenhouse gas emissions.”

Some of the fill comes from private sources, such as housing, condo and office building developments. The project generates revenue through tipping fees from these private fill suppliers. “By treating fill as a resource, we can create a beautiful conservation area in the heart of a heavily populated area,” said Farr.

“The new conservation area will bring back much of the natural habitat and function that was lost over time,” said Kate Hayes, Manager, Aquatic Ecosystem Restoration for Credit Valley Conservation. “This includes creating two new wetlands, resuscitating a buried creek and creating valuable meadow, forest and beach habitat. Underwater, just off shore, we’ll create habitat features like spawning shoals for fish.”

Fill material selected to create the new conservation area is clean and inert. This ensures that the lake is protected and that trees and shrubs planted in the new conservation area will thrive.

“Source sites for fill material are tested at a lab to make sure it’s clean and suitable for use onsite,” said Kenneth Dion, Senior Manager, Special Projects for Toronto and Region Conservation Authority. “Observations are also made of each load when it first enters the site and before it’s placed to ensure that the material arriving matches the materials from the approved source site.”

The eastern Mississauga waterfront has been heavily developed and currently supports little habitat for wildlife. The new conservation area will replace the existing shoreline with a more natural, diverse and ecologically functional shoreline. A larger connected stretch of beach will provide habitat for birds and fish as well as an opportunity for residents to connect with the lake. Three rocky islands will be built offshore to absorb heavy waves from the lake and provide sheltered areas for fish.

The streams that currently flow through the site, Applewood Creek and Serson Creek, will feed into wetlands before they enter the lake. Wetlands provide wildlife habitat and naturally clean water before it enters Lake Ontario.
