Following a recent review of regional land use plans, the Ontario government is proposing changes that could dramatically impact the way water is managed on the landscape.
According to the government’s summary, Shaping Land-Use in the Greater Golden Horseshoe, “Under proposed new policies in the Growth Plan, Greenbelt Plan and Oak Ridges Moraine Conservation Plan, municipalities would be required to develop plans for managing stormwater in their settlement areas. These plans would incorporate…

Stormwater management ponds have long been the infrastructure of choice for managing runoff from roads, parking lots and other impermeable surfaces. While stormwater ponds do a good job of slowing the surge of water during a rain storm and collecting sediment, they often do little to treat pollution. Further, standing water often experiences an increase in temperature. Warm water has lower…
With assistance from Lake Simcoe Region Conservation Authority (LSRCA)
Like many lakes impacted by urbanization, Ontario’s Lake Simcoe ecosystem faces challenges. This has long been recognized, and governments have been taking steps to protect and restore this ecosystem with multiple solutions, including green infrastructure.
To learn more about how the Lake Simcoe Region Conservation Authority (LSRCA) is supporting better site design practices and green infrastructure join us for our webinar…
Rain falls on a city – but instead of running off into a storm drain, it flows into a curbside rain garden, off a roof into a cistern, or is absorbed into vegetation planted on roofs.
What is this called?
Storm drains and pipes are known as grey infrastructure – there’s no debate about that. But techniques for managing rain where it falls, including rain gardens, bioswales, infiltration galleries, green roofs and cisterns are known by many names.
In the Umbrella bulletin, we tend to use the…
There are many myths about green infrastructure – and many good counterarguments. One of the most persistent myths is that Canada’s winter weather makes green infrastructure impractical. We hear it all the time: “This might work in temperate climates in Europe or the U.S. But we have winter!”
This argument is not supported by the evidence.
Some of the most progressive cities that rely on green infrastructure for stormwater management have harsh winters. Milwaukee, Wisconsin has a very…
Walk by a busy commercial intersection in Peterborough, a schoolyard in Ottawa, a kids play area in Kingston, and a residential alleyway in Montreal, and you might notice some big changes. All of these sites are part of the 2015 Depave Paradise program, in which community groups partnering with site hosts get volunteers to tear up unused pavement and replace it with native plants and trees.
Long promoted as a tool for water conservation, rain barrels are emerging as a simple low-cost method of on-site stormwater management.
Collecting roof runoff is valuable whether the goal is to save water or manage rain where it falls. But if the goal is runoff volume reductions, municipalities need to promote the right messages.
- Install more rain barrels. One or two barrels might hold all the water the average gardener wants, but they won’t come close to collecting the runoff from most…
Faced with the combined impacts of urbanization and climate change, how can municipalities take action across the landscape to reduce flood risk, erosion, and pollution?
A free workshop, being held Wednesday 2 December in Toronto, will outline tools for community-scale adoption of green stormwater infrastructure (low impact development).
The half-day workshop will provide a strategic overview for ways to implement innovative stormwater solutions on public and private lands, including of…
After years of chronic underfunding of stormwater infrastructure, many Canadian cities are looking to a new model of charging dedicated lot-level stormwater management fees.
This approach, often known as the stormwater utility model, has multiple advantages: reliable revenues, fairness, and the opportunity to incent measures that reduce runoff through onsite infiltration, harvesting, and reuse.
Join us for a webinar on 28 October featuring representatives from three Canadian municipalities…
When land is being torn up anyway, there are often opportunities for managing runoff with green infrastructure.
Regulating new development and redevelopment projects to manage stormwater on site is becoming the norm in many cities. However, in most cities, development and redevelopment is only a small portion of the land area. In order to meet water quality and flood protection goals, municipalities are getting creative with finding opportunities to manage stormwater.
Seattle provides one…
