The purpose of the Maitland Park Stream Restoration Project is to provide protection to the Chinguacousy Trail within Maitland Park while simultaneously identifying opportunities for renaturalization of the banks and parkland. This work will offer more long-term and sustainable protection to the area.
TRCA is working on behalf of the City of Brampton to help restore waterways within the city. The funding for this project was provided by the Clean Water and Wastewater Fund (CWWF), which aims to improve and maintain reliable drinking water, stormwater and wastewater infrastructure to communities.
The restoration works for the Maitland Park Stream Restoration Project are planned to commence this month. In order to maintain public safety during construction, a portion of the trail will be closed off from public access. The trail closures and alternative routes related to this project are referenced below.
TRCA hosted a design charrette on July 16, 2018 with a variety of professionals from multiple disciplines, including fluvial geomorphology, construction management, water resources engineering, and planning ecology. The purpose of this meeting was to brainstorm innovative approaches to reinvigorating a portion of Etobicoke Creek within Maitland Park. Suggestions from the multi-disciplinary group were documented and incorporated into the concept and detailed designs.
During an inventory walkthrough performed in 2009, Toronto and Region Conservation Authority (TRCA) staff noted several erosion control structures within Maitland park which were in various states of deterioration. These structures included a concrete channel, as well as several rip rap and gabion basket revetments which protected the nearby park path and sanitary sewer line. In 2018, this site was identified as a candidate for the Clean Water and Wastewater Funding (CWWF) to be addressed by TRCA on behalf of the City of Brampton.
This project was also identified as an ideal candidate for a collaborative initiative between TRCA and the City of Brampton with input from the Canadian Chapter of the International Erosion Control Association (CAN-IECA). This collaborative effort facilitated a holistic approach to addressing various concerns related to erosion, ecology, public safety and other disciplines.
In order to meet and exceed the goals set out for this project, TRCA plans to incorporate a series of improvements along this stretch of Spring Creek (a tributary of Etobicoke Creek) within Maitland Park.
The design includes the removal of a portion of the pre-existing concrete channel that extends downstream of the bridge at North Park Drive. Removing a portion of the concrete channel would provide opportunity for channel habitat improvement. The design also includes bank renaturalization and a pool and riffle sequence, to reduce flow velocity and improve channel morphology. The installation of a vegetated buttress and armourstone wall will provide the bank with stability and mitigate erosive forces currently threatening the adjacent public trail.
