    FLASHBACK TO 2015: Release of “Beyond the Guidebook 2015” drew attention to what Watershed Health issue means in practice and provincial game-changers that enable local government action in British Columbia


    In British Columbia, three landmark provincial initiatives came to fruition in 2014. All embody the enabling philosophy. “Looking into the future, collaboratively developed Water Sustainability Plans can integrate water and land use planning and can be combined with other local, regional or provincial planning processes to address water-related issues. “The scale and scope of each plan – and the process used to develop it – would be unique, and would reflect the needs and interests of the watersheds affected,” states Jennifer Vigano.

    Watershed Case Profile Series: “Water Balance Approach on Vancouver Island” (released January 2018)


    The storyline is built around three regional Water Balance Methodology demonstration applications. “To be useful…the simulation model must be physically based and deterministic, and it must be designed to simulate the entire hydrological cycle…hence it must be a water balance model,” wrote Ray Linsley (1917-1990). He pioneered development of continuous hydrologic simulation as the foundation for water balance modelling. The Water Balance Methodology is a synthesis of watershed hydrology and stream dynamics.

    YEAR IN REVIEW: “In 2017. the Partnership for Water Sustainability greatly enhanced the capabilities of the Water Balance family of tools to make real the vision for the ‘BC Framework’ for sustainable service delivery,” stated Ted van der Gulik, President, when reflecting on program accomplishments


    No longer is asset management only about hard engineered assets – watermains, sewers, roads. Watershed systems are also “infrastructure assets”. Asset Management for Sustainable Service Delivery: A BC Framework sets a strategic direction that would refocus business processes on outcomes that reduce life-cycle costs and risks. “Financial support from three levels of government makes it possible for the Partnership for Water Sustainability to develop tools, resources and programs,” stated Ted van der Gulik.

    Voodoo Hydrology Annual Webinar Series (December 2017): Andy Reese explains the pitfalls of urban hydrology methods


    Andy Reese coined the term Voodoo Hydrology in 2006. “As a stormwater community, we have for years relied upon common urban stormwater hydrologic design methodologies and trusted their results. But, should we? We must understand that urban hydrology, including newer Green Infrastructure sizing approaches, as commonly practiced, is an inexact science where we are simply trying to get close to the right answer,” states Andy Reese.

    IMPLEMENTATION OF WHOLE-SYSTEM, WATER BALANCE APPROACH: “The challenge is to move from stop-gap remediation of in-stream problems to long-term restoration of a properly functioning watershed,” stated Peter Law, Vice-President of the Mid Vancouver Habitat Enhancement Society


    “By sharing the story of Shelly Creek, we want readers to recognize that erosion is a common issue impacting salmon and trout habitats in small streams, draining into the Salish Sea,” states Peter Law. “Existing standards of practice have resulted in negative impacts. Continuing to use those standards will result in further environmental degradation of the watershed and loss of stream productivity. Building support for action starts with community engagement.”

    DESIGN WITH NATURE BECAUSE: "The reality of climate change has exposed the hubris of the pave, pipe and pump mentality that has dominated urban development for over a century," wrote Sophie Knight in an article for the Guardian newspaper's resilient cities page


    “As the recent floods from Bangladesh to Texas show, it’s not just the unprecedented magnitude of storms that can cause disaster: it’s urbanisation,” observed Sophie Knight. “A recent survey of global city authorities carried out by the environmental non-profit CDP found 103 cities were at serious risk of flooding. With climate change both a reality and threat, many architects and urbanists are pushing creative initiatives for cities that treat stormwater as a resource, rather than a hazard.”

    Interview offers insight into ‘watershed / stream’ approach: What makes BC’s stormwater approach different than other jurisdictions in North America?


    James Careless had an assignment to look into stormwater modelling tools (for projecting flow and other patterns); both to determine the most common tools used, and some of the most innovative approaches that are coming into use. His research into BC’s water balance approach led him to switch gears from an examination of modelling tools to learning what ‘establishing watershed objectives for stormwater management’ means in practice.

    SUSTAINABLE WATERSHED SYSTEMS: “The Gibsons Eco-Asset Strategy allows the Town to bring the value of nature into the DNA of municipal decision-making,” states Emanuel Machado, Chief Administrative Officer


    Gibsons is leading by example in successfully implementing its visionary Eco-Asset Strategy. The Town is the Living Laboratory for the Municipal Natural Assets Initiative. It is also a demonstration application for Sustainable Watershed Systems, through Asset Management. “Since declaring Nature its most valuable infrastructure asset, the Town has integrated the Eco-Asset Strategy into everything that the municipality does,” states Emanuel Machado.

    ANNOUNCEMENT: Partnership for Water Sustainability in British Columbia re-builds and re-launches waterbalance.ca website for easy access to an array of online tools that support the vision for "Sustainable Watershed Systems, through Asset Management" (Sept 2017)


    “The current industry-wide move to on-line computation, propelled by changing approaches to software delivery as a multitude of enterprises commit to The Cloud, is hugely important,” stated Dr. Charles Rowney. “The leadership shown by the Partnership for Water Sustainability in decisively moving in this direction well over a decade ago has led to a body of knowledge from which others can learn.”

    SUSTAINABLE WATERSHED SYSTEMS: Flood, drought, fire, wind and cold – because extreme events are becoming the norm…..


    As communities face the increasing impacts of climate change, there is an unfunded liability – the cost to restore watershed hydrology and water resilience in the built environment. “The Partnership for Water Sustainability is evolving, online tools that support implementation of the whole-system, water balance approach. British Columbia, Washington State and California are leaders. We are moving forward in parallel on this journey,” states Jim Dumont.
