Etobicoke Valley Park Major Maintenance Project

Toronto and Region Conservation Authority (TRCA) is preparing to undertake a major maintenance project along Etobicoke Creek where failed and failing erosion control structures are currently placing the multi-use Etobicoke Creek trail at risk of further riverine erosion and slope instability.

Project Site

The project site is located at two existing erosion control structures, a gabion basket retaining wall and a fieldstone revetment. Both structures show signs of significant degradation since their construction and were classified as ‘high priority’ in February 2018 for major maintenance works due to their proximity to sections of the multi-use Etobicoke Creek trail.

Project Duration

Work is tentatively scheduled to begin in early 2019, pending receipt of all necessary permits and approvals, and is anticipated to be completed in the spring, 2019.

Scope of Work

Work will begin with the construction of a stone ramp into the watercourse to access the underside of the gabion baskets. Where the lower baskets have been removed, large stones will be stuffed into the voids and along the front to add support to the upper baskets. Working in an upstream to downstream manner, the stones will be placed in front of the baskets as the access road is removed.

Once equipment is out of the water, work will recommence from the top of bank. A bank stabilization measure involving the installation of large stones and dormant vegetation will be constructed for the remaining section. Following the bank work, a post-and-paddle fence will be installed adjacent to the path.

During favourable weather, plantings and paving of the park trail will begin.

Construction Information

Please obey all posted construction signage and stay clear of work areas and equipment.To protect your safety, we ask the public to exercise caution and stay clear of the work area and equipment while the project is underway.

During work hours, typically Monday to Friday 6:30 AM — 4:00 PM, dump trucks and other vehicular traffic will be travelling on all highlighted routes  and the trail will be closed from the playground/stockpile area to 350 metres south, beyond the work area (see Project Information Map).

On evenings and weekends, the trail around the work area will be opened. During the winter months, the trail is unmaintained by City of Toronto staff and will only be maintained by TRCA for the safe operation of vehicles and staff during construction.

Current News

Week of October 29, 2019

Paving work is anticipated to begin the week of November 4th and should take only one day to complete. Pedestrians will be able to walk around the work area most of the time, however trail users should expect some delays due to temporary, intermittent trail closures as construction equipment is being set up. Cyclists are asked to dismount and walk their bikes around any construction activity.

Please be reminded that paving trucks and equipment will be on site traveling from Horner Avenue into the park where the new vegetated buttress has been installed, so it is prudent to comply with all posted signage and obey flagmen that are guiding trucks to and from site.

Week of September 9, 2019

The post-and-paddle fence has been installed and construction crews are no longer present on site within Etobicoke Valley Park. Terraseeding of all disturbed areas has been completed. Over the next week, the entrance to Etobicoke Valley Park and the paved pathway leading to the former worksite will be swept to remove any left-over debris. Damage to the paved pathway is currently being assessed and will be planned accordingly.

Restoration work, including plantings, installing live stakes, and minor asphalt resurfacing, will continue intermittently into the fall.

During this phase of work, the paved pathway running along Etobicoke Valley Creek will be open. Please be reminded that trucks may be on-site occasionally for restoration work, so it is prudent to comply with all posted signage and obey flagmen that are guiding trucks to and from site.

Week of August 23, 2019

Construction of the vegetated buttress, Flex-MSE wall and the post-and-paddle fence have been completed. Over the next week, on-site construction staff will be removing granular from the paved pathway, taking down construction fencing and preparing the site for restoration plantings.

During this phase of work, the paved pathway running along Etobicoke Valley Creek will be open. Please be reminded that trucks will be on-site occasionally, so it is prudent to comply with all posted signage and obey flagmen that are guiding trucks to and from site.

Restoration is expected to continue over the next few weeks, and will include seeding, planting, and paving.

Week of August 19, 2019

Construction of the vegetated buttress is now complete. Construction staff have begun working to complete the Flex-MSE wall at the downstream end, which involves layering Flex-MSE bags at the base of the armourstone wall and filling in the eroded bank with small stone and top soil. Following completion of the Flex-MSE wall, construction staff will begin working to complete the post-and-paddle fence at the upstream end of site. 

During this phase of construction, the paved pathway running along Etobicoke Valley Creek will be open. Please be reminded that FlexMSE bags and other materials continue to be delivered to the site daily, so it is prudent to comply with all posted signage and obey flagpeople that are guiding trucks to and from site.

Week of August 15, 2019

Construction of the toe protection at the upstream portion of the work area is now complete. Construction of the vegetated buttress is now ongoing, which involves placing stone in the creek at the toe of the structure and layering rock, soil and vegetation to the bank. Following completion of the vegetated buttress, construction staff will begin working to complete the Flex-MSE (Mechanically Stabilized Earth) wall at the downstream end.

Please be reminded that stone and other materials continue to be delivered to the site daily, so it is prudent to comply with all posted signage and stay clear of the work site. The paved pathway running along Etobicoke Valley Creek through the construction site continues to be closed Monday-Friday from 7:00 AM – 5:00 PM.

Week of July 22, 2019

Construction crews are on site coordinating material deliveries and preparing to begin active construction.

Please note that the paved pathway running along Etobicoke Valley Creek through the construction site will be closed Monday-Friday from 7:00 AM – 5:00 PM.

Week of July 8, 2019

Work is tentatively scheduled to being in mid July 2019, pending receipt of all necessary permits and approvals.

Week of February 18, 2019

The Etobicoke Valley Park Minor Maintenance Project has been rescheduled to begin in Summer 2019.

In accordance with TRCA best management practice, a few trees at the work site will be removed in Winter 2019, to avoid migratory bird nesting season.

Week of January 28, 2019

Construction has been temporarily delayed.
