Rainwater Management

“We knew more than 20 years ago what we needed to do when designing residential communities, but local governments generally failed to act. Turning the situation around is SIMPLE when you understand hydrology. And when you understand the kinds of changes needed in development practices, and the differences they would make, property to neighhourhood to watershed. We are saying there is a way of designing communities and making decisions differently so that you can be restorative in nature within the urban development context,” stated Richard Boase.

“As the American West and other regions dry out, they’re searching for ways to produce more water themselves, instead of importing it by aqueduct,” wrote Matt Simon. “So the old way of stormwater management isn’t just increasingly dangerous and ineffective as the planet warms and storms get more intense—it stands in the way of a more beautiful, less sweltering, more sustainable urban landscape. LA, of all places, is showing the world there’s a better way.”

“Because nature is a system, you cannot slice and dice it. EAP, the Ecological Accounting Process, recognizes this and is a financial tool to give streams the support they need to survive in the local government setting. EAP provides a value picture of a stream system as a land use. The Riparian Areas Protection Regulation enables this approach. The foundational ideas behind what we advocate are IMPLEMENTATION and RESPONSIBILITY. And there is a third idea named OPPORTUNITY,” stated Tim Pringle.

Resource protection – for groundwater supply and fisheries habitat – is the original driver for implementing ‘green infrastructure’ in Langley. Township staff have learned and adapted. Langley has led by example and implemented a ‘water balance’ approach to large-scale residential projects. Moving ahead on a ‘green’ platform gained momentum as standard practice evolved through ‘learn by doing’ experience. “The term ‘blue link’ describes the purpose of the current drainage standard in Langley. It replaced the traditional curb-and-gutter detail for all but arterial roadways,” stated Ramin Seifi.

“When I looked at the history of the DCC Bylaw updates, staff had tried to take it forward several times. They would almost get to the finish line, then trip and fall. Each time, it seems that they started fresh instead of looking at why the previous attempts had failed. The first thing I did was look at WHY THEY FAILED. They tripped over being too complicated or getting sidetracked. Keeping it simple and basic is what got the DCC Bylaw over the line. In five years, we can update it and make it more complex if we need to. Now we at least have an updated bylaw adopted,” stated Melony Burton.

“The notion of a superficial understanding explains the challenge that I am seeing. There are post-2000 graduate engineers coming out of university who are familiar with green infrastructure ideas and concepts, but they do not know the details behind them: details that they did not have to know at university or in their previous jobs. Sure, they understand rainwater management ideas and concepts at a high level. But without the background and history, can they really appreciate why certain targets and approaches were selected while others were not?” stated Robert Hicks.

“There is a need for a new approach to hydrologic design, Jim Dumont advocated in the mid-2000s. So, Fergus Creek became the pilot for a runoff-based approach because duration of discharge links directly to stream health,” stated Rémi Dubé. “In 2006, when Surrey hosted the showcasing green innovation innovation series, Jim and I said that Fergus Creek is going beyond the guidebook. The phrase stuck. Fergus led to the Beyond the Guidebook Initiative. Jim also maintained that what the watershed will look like in future should drive the approach to rainwater management.”

“In the 2000s, Fergus Creek was the first of the new generation of watershed plans in the City of Surrey. The Fergus Creek plan showed why and how contiguous greenways make rainwater management easier and provide the land we need to actually achieve multi-purpose outcomes. In 2009, we framed the nature of the paradigm-shift with this statement: Surrey is moving beyond green infrastructure pilot projects to a broader watersheds objectives approach. From this precedent emerged the framework for Surrey’s Biodiversity Conservation Strategy,” stated Rémi Dubé.

“There are so many benefits associated with watercourses that go well beyond moving water from A to B. This understanding is reflected in our Biodiversity Conservation Strategy. Without our watercourses, Surrey would feel different. It would not be the place that it is. In the uplands, it is the biodiversity piece. And going beyond just setting a corridor to ask, how can we enhance that corridor to maximize the biodiversity value it brings. On the coast and in the lowlands, we have been focusing on flood resiliency and adaptation,” stated Samantha Ward.

“You observe what happens. And then you can try to apply that understanding in your simulations or your designs when building something. Look at things! Do not just sit in a room with a computer. You have got to be out there watching and trying to understand what is happening in nature. I describe this as research with a purpose. In the Sustainability Charter (2008) we made a commitment that the City would not just ask developers to do things. We said we would do those things on City developments as well. And we would test them at our own cost,” stated Carrie Baron.
