“The Canadians do appear to be ahead of the US in this field because the US EPA took a really bad approach to LID that was based on the premise that enforcing every site to the same standard would somehow fix the problems of water quality in the US,” commented Paul Crabtree. “The USA EPA approach has done some good, but has several crippling drawbacks."
"Instead of expanding our infrastructure, we put together a plan to price, value, reuse, recycle, infiltrate, transpire or otherwise manage, every drop of rainwater we could. We started to invent the millions of ways to reduce the amount of rainwater that arrived at our sewer inlets. The goal was to consider rainwater as a commodity and a resource—if it enters a sewer drain it becomes a costly waste product," explained Howard Neukrug.
At a Special Meeting held in October 2011, the Metro Vancouver Board amended the 2012 Budget to include a grant for the Water Balance Model / Express. “Metro Vancouver has contributed $50,000 to fund further enhancement of the Water Balance Model because widespread use of this decision tool will help Metro Vancouver and members fulfil our regulatory commitments, in particular those related to integrated rainwater management,” stated Port Coquitlam Mayor Greg Moore, Board Chair.
At the Surrey Forum, Remi Dubé provided an historical perspective on how drainage planning in Surrey has evolved since the 1970s, and how key neighbourhoods embody the Surrey sustainability vision. "There is a fundamental difference between Surrey and other Metro Vancouver municipalities,” stated Remi Dubé. “Surrey has moved beyond pilot projects; we are moving to a broader watershed objectives approach to capturing rain where it falls to protect our streams.”
The inspiration for “Peeling Back the Pavement” was a report titled Re-Inventing Rainwater Management: A Strategy to Protect Health and Restore Resources in the Capital Region. "Environmental and stream health problems in the Capital Region are the legacy of an obsolete 19th century stormwater management system—a system that fails to respect natural systems and water cycles,” states Calvin Sandborn.
A value-added dimension to the SmartStorm Forum Series was the involvement of elected representatives. Mayor Barry Janyk of the Town of Gibsons was the moderator for the last three in the series. "The response to the SmartStorm Forum Series was simply overwhelming," recalls Mayor Janyk,
The Water Balance Methodology has its genesis in the whole-system approach that Dr. Ray Linsley (1917-1990) championed more than 60 years ago. As a professor at Stanford University, he pioneered the development of continuous hydrologic simulation as the foundation for water balance management. In the 1960s, Linsley championed the paradigm-shift from empirical relationships to computer simulation of hydrologic processes.
"Local governments bear the entire financial burden to stabilize watercourses impacted by increased runoff volume after land is developed. The challenge is to think about what infrastructure asset management entails BEFORE an asset is proposed and incorporated in a municipality’s capital plan," states Ray Fung.
“It is the combination of diverse needs, ideas and solutions that will make the vision for the Center work,” stated Dr. Rowney. “That is one of the reasons we’re so pleased with the agreement just reached with the British Columbia Partnership for Water Sustainability. We have many needs in common, and many ideas to share. The leadership shown by the Partnership has led to a body of knowledge from which others can learn."
“So what is the nub of the issue? In standard practice, only surface runoff is considered, and this has led to degraded streams. The other pathways by which rainfall reaches streams are ignored,” explained Jim Dumont. “If communities are to truly benefit from use of nature’s assets to provide vital community infrastructure services, then we must change the engineering standard-of practice to one that is state-of-the-art and reflects real-world hydrology.”
