| − | Glendale Public School in Brampton faced increased urbanization, limited stormwater controls, and on-site drainage issues that were harming aquatic health in nearby Fletchers Creek, particularly the endangered Redside Dace. To address these concerns, CVC designed a large-scale rain garden using a treatment-train approach, incorporating three swales, conveyance pipes, an underdrain system, and a flow-control valve. | + | [[File:Screenshot 2025-11-14 140403.png|400px|thumb|right|Glendale Public School rain garden.]] |
