Rainwater Management

“Released in 2002, the Guidebook provides a framework for effective rainwater management throughout the province. This tool for local governments presents a methodology for moving from planning to action that focuses on implementing early action where it is most needed,” states Laura Maclean. “The Guidebook approach is designed to eliminate the root cause of negative ecological and property impacts of rainwater runoff by addressing the complete spectrum of rainfall events. The Guidebook approach contrasts with conventional ‘flows-and-pipes’ stormwater management.”

“Now that we have landed on the Riparian Deficit concept, we are able to reflect on the two issues which provided context for the journey: first, engineering measures are insufficient for stream and riparian protection; and secondly, the link to municipal asset management has not been clear. To reach the destination, we had to address and show how to overcome four challenges: one, a lack of measurable metrics; two, confusion over what is an asset versus a service; three, ignorance about how to quantify the financial value of natural assets with real numbers; and four, numerous one-off projects that fail to build improved asset management practice,” stated Tim Pringle.

“Have a look at some of the Water Balance Model slideshow presentations that have been made to industry and government groups starting in 2001. This includes some of the early presentations on the Water Balance Methodology that helped pave the way for the paradigm-shift from 'peak flow thinking' to 'volume-based thinking'. The many presentations created awareness and influenced expectations,” stated Ted van der Gulik.

“I got a call from Don Stenson, Director of Planning with the City of Burnaby. He said there is one thing that I want you to never forget… STORMWATER. What does stormwater have to do with anything, I thought. I knew about contaminated soil and geotechnical issues. But stormwater? I had never encountered the word. But there is no doubt, he went on to say, that it is going to be very important that whatever you build on top of that mountain, the stormwater flows into Stoney Creek must be no worse than they are today,” stated Michael Geller.

“If we are to challenge how urban development has taken place without a deep understanding of our connection to nature, what is a strategy for bringing nature back into cities? How do we put nature first without pushing people aside? The answer is that it is about bringing a body of methodology and practice as to actually how to do it. Nature-First Cities is not a heavy academic book. We wrote it to be inspirational. We challenge readers to understand why we have become so disconnected from nature and what happens when we start to rebuild that connection,” stated Sean Markey.

Julia Berry applied original thinking to core concepts and produced an evaluation framework for Ecosystem-based adaptation (EbA). Her thesis is a foundation piece in a building blocks process that stretches over time. Publication of Nature-First Cities in 2024 is the latest milestone in that process. “Adapting to climate change will require a combination of approaches, from man-made infrastructure to holistic approaches. British Columbia’s Stormwater Planning Guidebook promotes a holistic approach to rainwater management,” stated Julia Berry.

Nature belongs in cities, but how do we put nature first without pushing people aside? Nature-First Cities reveals the false dichotomy of that question by recognizing that people and nature are indivisible. This new book is a guide to building urban ecosystems. “Prepare to be entertained, educated, and stirred to advocate for nature-oriented cities. Brewer, Hammond, and Markey, discontent with band-aids and wishful thinking in the face of planetary crises, address the core of what threatens our survival,” stated Cherise Burda.

“At Washington State University, I study urban stormwater runoff and its impacts on aquatic animals. The really exciting thing about the research that we are doing, and the results we are getting, is that it gives people hope. Green stormwater infrastructure really can be part of the solution,” stated Jenifer McIntyre. “Our research shows that for all experimental combinations, the bioretention system ELIMINATED the toxicity. Not reduced. Completely eliminated! Rain gardens can save salmon.”

The context for the Partnership for Water Sustainability celebrating the life of Barry Janyk is the Smartstorm Forum Series. This transformational series fueled a movement and galvanized an ecosystem-based approach to rainwater management and green infrastructure within the Georgia Basin bioregion of southwestern British Columbia. Barry Janyk, who was then mayor of Gibsons, infused the SmartStorm Forum Series with his passion. He was the political champion who carried the green infrastructure torch to the Metro Vancouver Regional Board and then to UBCM.

“The stream systems component of the region’s first two LWMPs drove changes in practice through the 2000s. The ecosystem-based approach emerged because of the need to remedy stream channel and corridor erosion and flooding. The unintended consequences and costs of land use practices were unfunded liabilities. Once the Minister of Environment approves an LWMP, it is legally binding. Thus, the LWMP is potentially an effective mechanism for influencing what we do within watersheds. The third LWMP is a window of opportunity to get it right,” stated Kim Stephens.

Between 2014 and 2022, the BC Ombudsperson published the Striking a Balance series of reports on riparian enforcement. Jay Chalke linked loss of riparian integrity to failure by local governments to employ adequate oversight of stream systems. In the late 2000s, the hollowing out of the environmental agencies meant they withdrew from former oversight and enforcement roles.

“Advances in science led to different paths along the west coast for British Columbia, California, Oregon and Washington. West Coast experience is a counterweight to those who lean to Ontario and northeast USA for their experience. But many in BC do not understand why mimicking flow duration is risk management. It baffles me why it is that way. Risk management is a really big deal,” states Jim Dumont.

“The 1990s was a very instrumental time of policy and regulation development. And municipal dialogue too. You felt like you were part of a movement. Those were such fantastic discussions and collegiality between municipalities. There was a really good alignment and call to action on making streamside regulation work. It was a major advancement but a lot of stress as well,” stated Susan Haid.
