“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.”
“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.
SUSTAINABLE WATERSHED SYSTEMS: What is the provincial government role in supporting BC communities so that they “get it right” when moving from policy to action in implementing initiatives flowing from the Living Water Smart framework?
“British Columbia is at a tipping point vis-à-vis Sustainable Watershed Systems. Without provincial government leadership and direction, the process to adopt, change or evolve standards of practice and apply tools in the local government setting may be painfully slow, might not happen, or could simply peter out due to indifference or neglect,” stated Kim Stephens. “As a minimum, provincial government support is necessary if communities are to “get it right” from a water balance perspective vis-à-vis land use, infrastructure servicing of land, and asset management.”
VIDEO: Langley Township has engineered several thriving ecosystems for its 1600 kilometres of watercourses
A culvert upgrade was needed where Yorkson Creek passes under 86 Avenue but instead of the usual round shape, the replacement in 2016 was square. “The previous narrow culvert caused water to rush through and made it difficult for fish to swim through. The new culvert has angled baffles on the bottom side which creates a meandering watercourse,” explained Justin St. Andrassy. “We installed pool and ripple sequences, habitat features, large woody debris, and we planted the entire restoration zone with native plantings over several years.”
VANCOUVER SUN OP-ED ARTICLE: Led by Asset Management BC, the BC Framework refocuses business processes on how physical and natural assets are used to deliver services, and support outcomes that reduce life-cycle costs and address risks (published on June 2, 2018)
Flood, drought, fire, wind and cold – extreme events are the New Normal. British Columbia is at a tipping point. When will communities adapt, and how? “Hydrology is the engine that powers ecological services. Thus, integration of the Partnership’s work within the BC Framework should accelerate implementation of the whole-system, water balance approach at the heart of the Partnership’s ‘Sustainable Watershed Systems, through Asset Management’ program,” stated Peter Law.
VIDEO: West Vancouver’s McDonald Creek Gets a Fish-Friendly Makeover Thanks to Volunteer Effort and City Support
A new rocky berm has given a West Vancouver creek a better connection to high tide ocean water and salmon are expected to benefit. “The district’s role was to coordinate the project. The Streamkeepers did all the hard work to fundraise and organize funding for the project. We hired the trades folks, the coordinator and marine biologist to do the design work, and the coastal engineer, and got the trucks organized,” stated John Barker. “This is a perfect example of stewardship groups coming together and working in collaboration with the district.”
FLASHBACK TO 2002: “The Guidebook premise that land development and watershed protection can be compatible represented a radical shift in thinking in 2002. It opened the door to implementing a regulatory approach to designing with nature,” stated Kim Stephens, Guidebook project manager & principal author
“Published in 2002, ‘Stormwater Planning: A Guidebook for British Columbia’ was a catalyst for change that resulted in BC achieving international recognition as a leader in implementing a natural systems approach to rainwater management,” stated Kim Stephens. In addition to Adaptive Management, the Guidebook introduced two innovations. The first was the concept of an Integrated Strategy for managing all the ‘rainfall-days’ that occur each year. The second innovation was the concept of performance targets for managing the rainfall spectrum.
YOUTUBE VIDEO: “An educational goal is that those who are involved in municipal land use and drainage would understand the vision for ‘Sustainable Watershed Systems, through Asset Management’,” stated Kim Stephens, keynote speaker at the Nanaimo Water Stewardship Symposium (April 2018)
“Part of that is the paradigm-shift to recognize watersheds as infrastructure assets,” stated Kim Stephens. “Whether you use the word deficit or liability, the significance is that we don’t have the money to refinance or replace our existing core infrastructure such as water, sewer or roads. So, a simple challenge to a municipal councillor or regional board member is: Why would you take on another unfunded liability called drainage – which is what you have been doing for a lifetime!”

“The worth of a creekshed is a package of ecological services made possible by the hydrology. These inter-dependent ecological systems provide uses we call nature; examples are wetlands, ponds, riparian areas, woodlands, habitat for flora and fauna, etc. These systems add appeal and quality to parks, greenways, trails, as well as opportunities to focus on natural processes such as salmon spawning and nesting sites,” stated Tim Pringle. “The next step is doing. A strategy is the path to success.”
SPONGE CITIES: “It’s important to make friends with water. We can make a water protection system a living system,” stated Kongjian Yu, the landscape architect who is famous for being the man who reintroduced ancient Chinese water systems to modern design
Kongjian Yu is best known for his “sponge cities”. President Xi Jinping and his government have adopted sponge cities as an urban planning and eco-city template. “The mottos of the sponge city are: Retain, adapt, slow down and reuse,” stated Kongjian Yu. “Based on thousands of years of Chinese wisdom, the first strategy is to contain water at the origin, when the rain falls from the sky on the ground. We have to keep the water.” Yu’s designs aim to build resilience in cities faced with rising sea levels, droughts and floods.
FLASHBACK TO 2003: “To provide a feedback loop for the Stormwater Planning Guidebook, the Regional District of Nanaimo developed and applied the At-Risk Methodology through a knowledge-based approach,” stated John Finnie, former General Manager of Environmental Services
“The most effective and affordable way to identify at-risk watersheds for priority action is to tap the knowledge of people within any regional district or municipality who have the necessary planning, ecology and engineering knowledge,” stated John Finnie. “If the right people with the right knowledge are involved at the start, a knowledge-based approach will be both time-efficient and cost-effective. Priority action should be focused in at-risk drainage catchments where there is both high pressure for land use change and a driver for action.”
