Strategies for implementing green stormwater infrastructure

Join us on the 27th of April to learn about tools for community-wide implementation of green stormwater infrastructure, presented by Green Communities Canada Executive Director Clifford Maynes.

See details and registration:

The webinar will provide an overview of programs and policies outlined in the Soak it Up! Toolkit, developed by our RAIN Community Solutions program.

The toolkit and webinar are designed for decision-makers, such as municipal staff and councillors, and influencers, like community organizations, professionals, and contractors.  

"We've created a succinct summary of all the implementation approaches for people who want to get a bird's eye view of the options," said Maynes.

"It's designed to help you develop an action strategy that works for your community," he said. "Once you've got a general view of the elements that are locally appropriate, you can follow the links for more detail."

A number of the tools address systematic implementation on public lands, including parks, road rights-of-way, alleys, parking lots, and school yards. Also included are ...[Read more]

Vancouver considers 90% target for rainwater capture. Vancouver city council is considering an ambitious proposal to create an integrated Rainwater Management Plan in which 90% of rainwater would be captured and treated by rain gardens and other natural features before entering surrounding water bodies.   

Standardizing green stormwater infrastructure practices. A national certification program is being created in the US to standardize installation, inspection, and maintenance of green stormwater infrastructure systems. This initiative will contribute to the development of a skilled workforce able to contribute to the building of sustainable communities.

A growing interest in rain gardens. A number of initiatives are helping homeowners build gardens that capture rain and allow it to soak into the ground—reducing the amount of water and sediment entering storm drains. Recently, a program was introduced to support the building of rain gardens in Glen Cairn, Ontario to help filter stormwater prior to it entering the Thames River. Established rain garden programs can be found in Thunder Bay, Edmonton and the Lake Simcoe watershed—as well as Seattle's robust RainWise program.
Public management of road salt usage needed. A study in Toronto has found that although the City has reduced its application of road salt by 26%, chloride levels continue to increase in local water bodies. An increase in chloride may be due to road salt applications on commercial properties and private homes.

Canadian green infrastructure funding may include nature-based services. Green Communities Canada and Green Infrastructure Ontario Coalition recently met with the Office of the Federal Infrastructure Minister which expressed an interest in expanding funding to include infrastructure that mimics or supports ecosystem services.


Flood loss avoidance benefits of green infrastructure for stormwater management. This study, conducted by the U.S. Environmental Protection Agency, evaluates potential scenarios for managing stormwater with the green infrastructure in new developments and redevelopments. The study focused on flood loss avoidance, and generated an estimate of the monetary value of flood avoidance that could be achieved by using green stormwater infrastructure to capture runoff.

How to evaluate tree health. Deep Root Green Infrastructure offers an online checklist of thirteen easy steps for evaluating tree health, and suggests ways to care for trees that are identified as needing rehabilitation. 

Ontario's Great Lakes Strategy- 2016. This progress report outlines the Strategy's accomplishments and new findings to date. It cites the upcoming low impact development guidance document that will be added to Ontario's Stormwater Management Planning and Design Guidelines, as well as the updated Provincial Policy Statement that directs municipalities to adopt stormwater management best practices in new development, including the use of green stormwater infrastructure.

The Umbrella Stormwater Bulletin is a free, monthly newsletter on green stormwater infrastructure published by the RAIN Community Solutions program of Green Communities Canada. Our audience is made up of municipal stormwater professionals, policymakers, academics, engineers, conservation authorities, nonprofits, and interested community members. We encourage submissions from our readers. Please contact the editor to submit a news item, blog idea, or event. RAIN Community Solutions builds support for and participation in stormwater innovations that reduce runoff by managing rain where it falls.
