    12 – LESSONS FROM THE PAST INFORM THE FUTURE IN METRO VANCOUVER: Twin Pillars of Stream System Integrity


    Puget Sound research correlated land use changes with impacts on streams. Hydrology and riparian integrity are of equal importance. “There are many factors that influence stream degradation. There is not a single smoking gun. Impervious area is the main culprit. But you can trash a stream just as badly by deforestation of the riparian zone as you can by paving over the headwaters with a mall,” says Chris May.

    14 – LESSONS FROM THE PAST INFORM THE FUTURE IN METRO VANCOUVER: Puget Sound research correlated land use changes with impacts on stream


    There are many factors that influence stream degradation. “So many studies manipulate a single variable out of context with the whole and its many additional variables. We, on the other hand, investigated whole systems in place, tying together measures of the landscape, stream habitat, and aquatic life,” stated Dr. Richard Horner, professor emeritus at the University of Washington in Seattle.

    CHRONICLE OF GREEN INFRASTRUCTURE INNOVATION IN METRO VANCOUVER: “With the housing issue dominating the conversation, how will you reframe the goal and objective for restoration of stream systems in a way that restores political commitment and rebuilds the coalition?” asks Ray Fung, stated Ray Fung, a retired Director of Engineering in local government (1st installment in a preview series)


    In the 1990s, there was trouble in paradise. In response, the provincial government launched the Georgia Basin Initiative. It was all hands on deck and catalyst for the green infrastructure movement. “Knowing what we know, you have to build new political commitment and basically start all over again in a new crucible phase…where you coalition-build to develop a new shared vision, etc. The task at hand is about how to redefine things in a new political environment so you would be able to get a new vision and new political commitment,” stated Ray Fung.

    CHRONICLE OF GREEN INFRASTRUCTURE INNOVATION IN METRO VANCOUVER: “Think about it – the Reference Panel has influenced the waste committee, the finance committee and the way we make decisions overall. The community benefits when there is ollaboration,” stated Pam Goldsmith-Jones, former mayor of West Vancouver (2005-2011)


    When the process for updating the Metro Vancouver region’s “Integrated Liquid Waste and Resource Management Plan” commenced in 2008, Metro Vancouver Regional District staff were enthusiastic about the role of the Reference Panel. Because there was trust with staff, and the Reference Panel had the attention of the politicians, the Reference Panel could say what staff could not. There was huge positive value in that. The Reference Panel reinforced desired outcomes with its recommendations.

    ADDRESSING AFFORDABLE HOUSING’S HIDDEN UTILITY COSTS: “When you go down four, five and six levels of underground excavation for high-rise building foundations, you are intercepting and dewatering the groundwater resource,” stated Robert Hicks, career engineer-planner in local government in the Metro Vancouver region of British Columbia


    “Land use intensification and redevelopment – where does that water go? I see the answer having two faces for RISK and LIABILITY. You are creating a drainage demand by preventing rainwater from reaching building foundations or removing groundwater at depth. But the other face is the lost opportunity because the water resource is not being managed in either a coordinated or holistic manner. Creating a drainage demand is the more immediate consequence of land use intensification. The loss of groundwater as an option for water supply is a future reckoning,” stated Robert Hicks.

    THE MISSION IS TO DEVELOP NEXT GENERATIONS OF LOCAL GOVERNMENT STAFFS: “The partnership between local governments and the MABRRI research institute at Vancouver Island University is the pilot for upscaling EAP, the Ecological Accounting Process,” stated Murray Walters, Manager of Water Services, Regional District of Nanaimo


    A theme dominating the news these days is the shortage of skilled, trained or qualified people. The EAP Partnership is part of the solution in the local government setting. Investing in people takes patience, commitment and time. There is no shortcut to build in-house capacity. The partners have committed to investing in youth at Vancouver Island University so that they have the understanding to apply EAP. “We are applying EAP to relatively small scale streams to illustrate its usefulness and effectiveness. The application of EAP will grow from there, I am sure,” stated Murray Walters.

    LOCAL GOVERNMENTS INVEST IN YOUTH AT VANCOUVER ISLAND UNIVERSITY: “Partnerships with local governments and others are essential. They allow students to work on collaborative projects. Everyone benefits,” stated Graham Sakaki, Manager, Mount Arrowsmith Regional Research Institute


    “There are lots of partnerships that exist for selfish reasons. But the EAP Partnership is selfless; and from all angles. It is a leap of faith for member local governments. Partnership for Water Sustainability commitment to passing the baton is unwavering. Vancouver Island University is all-in because EAP is an idea that can change the game. And students are excited to contribute to the change. Students will be creating a portfolio of professionals who they know. These are important relationships for them to make. And they are gaining important knowledge too,” stated Graham Sakaki.

    ROAD MAP FOR STREAM SYSTEM INTEGRITY: The enduring legacy of Richard Horner and Chris May is that they applied systems thinking, investigated whole systems in place, identified four limiting factors, and definitively established their order-of-priority


    In the 1990s, Puget Sound research correlated land use changes with impacts on stream system condition. “So many studies manipulate a single variable out of context with the whole and its many additional variables. We, on the other hand, investigated whole systems in place, tying together measures of the landscape, stream habitat, and aquatic life. Unless and until land development practices mimic the natural water balance, communities cannot expect to restore the biological communities within streams. Simply put, hydrology hits first and hardest,” stated Richard Horner.

    LAND DEVELOPMENT AND WATERSHED PROTECTION CAN BE COMPATIBLE: “1997, a presentation on the science of land use change by Kim Stephens and Bill Derry helped an inter-ministry working group realize that we needed more than a setback to protect aquatic habitat. The science shows that communities also need to tackle what is happening on the land that drains to streams,” stated Peter Law, Chair of the former Guidebook Steering Committee, on the 20th anniversary of Guidebook publication (June 2022)


    “I found the opportunity to ‘look beyond the stream’ and address poor water quality from drainage runoff in the Waste Management Act. The opportunity resided in the non-point source provision for Liquid Waste Management Plans. The term non-point source pollution was used by my colleagues in the Waste Management Branch to highlight poor quality of runoff from developed and/or developing lands. But this provision was not being applied to the issue of how land is developed. So, I asked my colleagues, why not use this mechanism to connect the dots between changes to the land and impacts on streams,” stated Peter Law.
