Stormwater Management Facility Improvements

As part of the City of Vaughan’s Stormwater Management Facility Improvements Program, infrastructure enhancements are underway at various locations across the city. These projects will enhance the functionality of existing stormwater management facilities, incorporate water quality benefits, increase sediment retention and mitigate flooding.

The City values the voice of the public and is dedicated to having constructive dialogue with the community that is open, transparent, accessible and inclusive. Citizens are invited to join conversations about municipal decisions that interest and/or impact them. Participate in upcoming virtual Public Information Centres to learn more about various planned stormwater projects, including the need for the proposed work, details about the construction impacts, timelines and the benefits of these improvements.

Virtual Public Information Centres were held on June 2 and 3. Thank you to all those who attended.

What is a stormwater management facility?

A stormwater management facility reduces volume, flow rates or pollutants fromstormwater runoff.

Examples of a stormwater management facility include wet ponds, dry ponds, wetlands, underground storage chambers or otherstormwater infrastructure implemented to reuse, collect, convey, detain, retain, or provide a discharge point for stormwater runoff.

Stormwater management ponds are designed and built to collect rainfall and surface water runoff. The purpose of these ponds is to maintain the health of streamsand stormwater infrastructure ensuring excess water has somewhere to go. The City of Vaughan maintains approximately140 stormwater management
ponds.

Stormwater management ponds can be differentiated by being either wet or dry. A wet pond is designed to maintain a permanent body of water within the pond area. A dry pond is designed to remain dry until a rain event occurs which may temporarily retain stormwater within the pond area.

Blackburn Pond

Blackburn Pond is a large open area located east of Balding Boulevard, south of Blackburn Boulevard and north-west of Bell Harbour Place. The area is currently designed as a dry pond facility and provides flood control for the contributing catchment area. The existing pond will be further excavated and converted into a wet pond with the addition of a permanent body of water. The project will improve the functionality of the existing stormwater management facility and incorporate water quality benefits. In addition, the proposed new design will provide water quality benefits, maintain existing flood control performance and improve access to the area for inspections and maintenance.

The Blackburn Pond project will include:

pond excavation and incorporation of a permanent body of water
the installation of access roads and retaining walls
modifications to the existing outlet structure from where the water flows out
the installation of armourstone
plantlife management and landscaping features

While work takes place, access to the area will be impacted. The site will be accessed from Blackburn Boulevard, on the north edge of the pond block. Increased truck traffic is expected during working hours. Traffic control requirements will be confirmed with the contractor. Access to existing trails within the pond will be blocked during construction. Access to existing properties/driveways will be maintained at all times.

Fencing will be installed along the perimeter of the pond block to impede public access to construction site. All construction activities will be carried out within the fenced area as to avoid public exposure to any construction equipment or materials. Should traffic control be required, all necessary measures will be taken to guarantee safe traffic at the access point.

Franklin Pond and Pondview Pond

Franklin Avenue Pond and Pondview Pond are undergoing upgrades to improve the functionality of the existing stormwater management facility and incorporate measures to solve historical flooding issues observed in the area. Franklin Pond is situated between Hefhill Court and Franklin Boulevard, and Pondview Pond is located within Hefhill Park. Both facilities are dry ponds, which means they provide flood control for the contributing catchment area, but local flooding issues have been identified in neighbouring properties. The proposed new design intends to address flooding issues and proposed solutions from past studies will be implemented.

The proposed design combines different measures that together will help manage flooding in the future and:

increase in the storage capacity of Pondview Pond

redirect excess flows from Franklin Pond to Pondview Pond through a pipe to be installed within Hefhill Park connecting both ponds

modify the existing outlet configuration of both ponds to provide proper flow control for the proposed conditions

redirect flow from three existing catch basins located on Franklin Avenue to bypass the existing sewer network and discharge directly to Pondview Pond

The combined scope of work includes:

Pondview Pond re-grading

construction of a retaining wall

the replacement of inlet and outlet structures (i.e. catch basins, sewers, manholes)

minor curb, sidewalk and boulevard re-grading

re-grading of upstream berm

vegetation management and restoration

While work takes place, access to the area will be impacted. Traffic control requirements will be confirmed with the contractor. Increased truck traffic is expected during work hours. Access to existing park amenities, including playground areas and tennis courts, will be limited or restricted during construction. Access to adjacent properties and driveways will be maintained at all times, however should disruptions occur, they will be addressed with the individual landowner.

As an increased safety measure, fencing will be installed along the perimeter of the pond block and along Hefhill Park to prevent public access to the site. All construction activities will be carried out within the fenced area to avoid public exposure to any construction equipment or materials. Access to Hefhill Park will be limited during construction.

These projects are partially funded by the federal government’s Disaster Mitigation and Adaptation Fund, and are anticipated to take place between January 2022 and August 2022. Timelines are subject to change.
