The City of Woodstock partnered with AECOM to bring new life to the C9 Stormwater Management Facility, a vital piece of infrastructure safeguarding water quality, flood protection, and public safety.
Through a full-service approach, AECOM led the condition assessment, natural heritage review, sediment sampling, bathymetric survey, tender preparation, permitting, and construction oversight. The project’s centerpiece: the removal of 625 m3 of accumulated sediment, restoring critical storage volumes for both water quality and quantity control.
Construction efforts focused not just on function, but also on the community and environmental impact. The forebay and permanent pool were rebuilt to meet City and Ministry of the Environment, Conservation and Parks (MECP) standards, while invasive phragmites were managed to restore native vegetation, improving biodiversity and long-term ecological health. Safety upgrades included railings, signage, and outlet structure repairs -all designed to make the site safer and more accessible.
Disturbed areas were stabilized with topsoil, hydroseeded with native seed mixtures, and reinforced with riprap and gravel to protect against future erosion.
What started as a routine sediment cleanout became a comprehensive rehabilitation, delivering a cleaner, safer, and more resilient facility that benefits both the ecosystem and the community it serves.
