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.

“In the 2000s, we were challenged with what the word integrated in ISMP meant. We already had modelling tools. But the difference was integrating them with policies, land use, the landscape, and a public engagement process. And so, we were all pioneers. But we lost momentum in the decade after 2010,” stated Ray Fung. “If you are talking about learnings, so what is the organizational learning? When we were trying to do stuff, we did not build in robust enough processes that would survive changes in personnel. Can we not learn to build on what people in the past have done?”

“Municipalities have limited access to science and they do not have time to do the science. So, why not use the students? Not only is it a benefit to community leaders, the students benefit because they are doing something that makes a difference. And so, connecting with Richard Boase in the 1990s was really fundamental because he is on the inside. Richard identified projects where the students could benefit directly and make a difference. To me, that was the opportunity,” stated Hans Schreier.

“Delta’s rain garden program started with a phone call from Deb Jones, a volunteer with the Cougar Creek Streamkeepers. In 2004, she approached me with a request that the municipality undertake a stormwater pilot infiltration pilot project in North Delta. We identified the opportunity to build the first rain garden at an elementary school. The project was a success and so was the ensuing program. Within the first decade, for example, Delta had constructed a total of 50-plus rain gardens. 10 of these were located at elementary schools,” stated Hugh Fraser.

“BC communities are experiencing the unintended environmental consequences of policy frameworks that have not been well implemented. But despair not. Knowledge and wisdom that would pull us back from the brink are waiting to be rediscovered and mobilized so that communities can change course in time. Charting a course through perilous waters starts with understanding WHY certain dots from the period 1997 through 2005 are foundational. The Fish Protection Act 1997 is one such dot. Yet this rich history may be largely ignored and/or forgotten,” stated Kim Stephens.

“In 2003, the City was clearly visionary when it first embraced and then formalized a watershed-based approach as a foundation piece in the Official Community Plan. By the latter part of the decade, however, Coquitlam was viewed by others in the region as the example of what not do. A noteworthy aspect of the Coquitlam story is how quickly municipal staff learned from experience, adapted their approach, and successfully instilled a new way of doing business. Coquitlam is the model for keeping things simple, practical, and implementable,’ stated Kim Stephens.

“When I became City Manager, the City’s approach to watershed-based community planning, rainwater management and green infrastructure was quite idealistic. As a result, the city could not implement what was proposed. We had to do a re-think. That is when we came up with the monicker net environmental benefit. So, what we did was to re-think things and say something is better than nothing. When we made those changes to on-site rainwater management requirements, they were good changes, and they were well received,” stated Pete Steblin.

“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.
