Humber Flats Stormwater Management Facility Environmental Assessment
Project Background
The City of Richmond Hill is undertaking an environmental assessment of the Humber Flats Stormwater Management Facility (SWMF 1-4) to determine its current state and identify and assess potential alternatives for rehabilitating the facility.
The Humber Flats SWMF is located within the valleylands between Bathurst Street and Red Cardinal Trail, which contributes to the East Humber River. The study area includes all parts of the facility, which consists of three main components (see map):
- A series of nine filter pads within the valleylands, referred to as the “eco park”;
- A quantity control dry pond upstream of Humberland Drive; and
- A wet detention pond south of Humberland Drive.
The facility was constructed in 1997 and has a total major drainage area of about 188 ha. Based on updated hydraulic modelling performed by the Toronto and Region Conservation Authority (TRCA), it was determined that 123 residential properties adjacent to the facility are located within the Regional floodplain. The primary purpose of this Study is to determine potential alternatives and identify the best means to reduce the number of residential properties within the floodplain by reducing the floodplain extents while maintaining the stormwater management function provided by the facility.
The study is being conducted in accordance with Schedule B of the Municipal Class Environmental Assessment (EA) process (October 2000, as amended in 2007, 2011, 2015 and 2023). As part of the class EA process, evaluation of alternatives, assessment of the potential environmental effects and identification of mitigation measures for potential adverse impacts will be conducted and presented through public and agency consultations. Upon completion of the study, a Project File Report documenting the planning and decision-making process will be prepared and made available for public review and comment.

To facilitate community input, an Open House was held on Wednesday, May 31 at the Oak Ridges Library, where residents were invited to join in the review and provide feedback on the proposed solutions for the rehabilitation of the Humber Flats Stormwater Management Facility. The Open House presented an overview of the project and study findings, alternative solutions considered, and the proposed solution. For those who were unable to attend the in-person event, an online survey was open to provide feedback between May 31 and June 18, 2023. The Open House presentation boards have been posted below: The notice of the Open House was mailed to homes in the nearby neighbourhood, and is posted here: |
