New Resources Showcase Green Infrastructure Leaders

Credit Valley Conservation (CVC) today released four case studies and a low impact development (LID) interactive map showcasing water innovation in-ground projects across the GTA with leading-edge stormwater management. The resources are posted on CVC’s web site at www.bealeader.ca/lidsites .

The featured projects demonstrate successful green infrastructure solutions operating in municipal settings, where urban stormwater is stored and treated on site. They highlight some of the innovative best practises in stormwater management currently operating within the GTA by industry and government leaders.

The case studies include:

  • Elm Drive Street Retrofit in Mississauga where six engineered garden planters and permeable pavement help treat and infiltrate road runoff on adjacent school property that has demonstrated a 100 per cent reduction of peak flows for 95 per cent of all rainfall events and 99 per cent removal of concerning pollutants.
  • Green Glade Senior Public School Rain Garden in Mississauga, featuring a rain garden installed to treat roof drainage and parking lot runoff and to eliminate nuisance ponding (which becomes dangerous ice in winter) from the parking lot.
  • George Richardson Stormwater Pond Retrofit in Newmarket where an innovative red sand filter in the treatment train of a demonstration site has improved water quality to Lake Simcoe by reducing phosphorus loadings by 23 kilograms per year. Phosphorus is particularly concerning because it contributes to algae growth in our waterways.

The LID map is an online Google-based tool that allows anyone in Ontario to submit and share their innovative stormwater projects. Each site on the map has its own project page containing photos, company logo, project description and lessons learned.

“The case studies and interactive map explore how public and private landowners, developers, consultants and contractors have worked together to overcome barriers and learn valuable lessons designing, installing and operating innovative water technologies producing impressive results,” said Christine Zimmer, Senior Manager, Protection and Restoration at CVC.

“We are proud of ours and many organizations’ efforts to build and operate these practises. By sharing challenges and lessons learned we can help propel green infrastructure practises across the province as we adapt to face the burdens of aging infrastructure and our changing climate,” added Zimmer. 

CVC is a leader in low impact development (LID) practises to treat urban runoff. LID is a rapidly developing field in stormwater management that uses advanced techniques such as rain gardens and permeable pavement to help rain water filter into the ground, reducing polluted runoff and lessening the likelihood of erosion and flooding. LID is one solution for addressing water management impacts in a holistic, sustainable manner.

Organizations interested in partnering with CVC to develop a case study profiling their low impact development practises are invited to write to sustainability@creditvalleyca.ca. Any organization wanting to feature an innovative stormwater management site on CVC’s interactive map can upload their project to www.bealeader.ca/LIDmap .
