Green Infrastructure

“Commencing with a launch announcement by the BC Minister of Environment in 2005, this community-of-practice has served an important function as the home for green infrastructure in British Columbia. Originally created to support the work of the Green Infrastructure Partnership, the community-of-practice now has a dual focus in supporting two interconnected initiatives, that is: EAP, the Ecological Accounting Process: and Asset Management for Sustainable Service Delivery in BC, which is led by Asset Management BC,” stated Mike Tanner, Waterbucket Chair.

“In 2016, the Partnership embarked upon a 6-year program of applied research to evolve EAP through a 3-stage building blocks process of testing, refining, and mainstreaming the methodology and metrics for financial valuation of stream systems. The program involved 9 case studies and 13 local governments and yielded 19 “big ideas” or foundational concepts. The program goal was to answer the question, how much should communities budget each year for maintenance and management of stream systems,” stated Tim Pringle.

During the period 2003 through 2010, the Green Infrastructure Partnership played a prominent role in leading change and assisting with implementation of the Water Sustainability Action Plan for British Columbia, primarily in the Metro Vancouver region. “I see my years of chairing the GIP as helping to get the ball rolling and ideas disseminated, on green infrastructure, all of which has subsequently been taken up by others to a much greater degree of implementation and success. Our efforts a decade ago moved the state of-the-art of green infrastructure to a more mainstream level,” said Paul Ham.

In 2007, the first Beyond the Guidebook guidance document provided a clear distinction between natural and engineered green infrastructure. “Two complementary strategies can ‘green’ a community and its infrastructure: first, preserving as much as possible of the natural green infrastructure; and secondly, promoting designs that soften the footprint of development,” wrote Susan Rutherford. “Green infrastructure design is engineering design that takes a ‘design with nature’ approach, to both mitigate the potential impacts of existing and future development and growth and to provide valuable services.”

“The story behind the story is about the importance of embedding knowledge of EAP into the youth who are going to be the future of our local governments. The framework that we have set up ensures this will happen. Vancouver Island University, as a smaller university, is very focused on applied research and community engagement. This is a good fit for the EAP mission. The program enhances the ability of students to take part in applied research and have direct links to future jobs with these local governments who are providing project work experience for students,” stated Graham Sakaki.

“Now how do we become educated? What are we bringing to the table that is going to help make good decisions? Politicians know how to get elected. But do they know all that other stuff that they need to know? Today, the people getting elected know how to use social media to get people to vote for them. But do they know and care about what matters in local government? To ask the tough questions, you must be informed and educated about what matters,” stated Darrell Mussatto.

“Asset management is a complex, arduous, exciting, long-term, involved process. As practitioners, we wholeheartedly embrace this journey because it empowers us to collaboratively make informed decisions about our infrastructure, ultimately benefiting the public we serve. But where do we begin? In the article, I explain what tools, documents, or processes I’m using to set the foundation for the asset management work to come in Abbotsford,” wrote Gracelyn Shannon. “With a better understanding of our stakeholders and current practices, we wrote our Asset Management Policy.”

“Local governments need data that is meaningful for infrastructure asset management, but quality and usefulness have emerged as issues of paramount concern. Before collecting data, make sure you ask the right questions,” states Kim Stephens. “Be clear on why data is needed. What is the desired outcome? How will you use the information or data? Will it help you make better decisions? How much and what kind of data do you actually need? Does the cost meet the test of being affordable and effective? What are the tradeoffs between risk, complexity and cost?”

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.

Because the audience comprised players involved in the land professions, the BC Land Summit was a watershed moment for showcasing new ideas. “The session about the Ecological Accounting Process began with Tim Pringle detailing EAP and its nine demonstration applications in local governments in BC. Then I spoke about Year 1 of the three-year transition strategy to transfer the knowledge and methodology of EAP from the Partnership to VIU. We concluded with a pre-recorded video segment by Sam Gerrand about incorporating EAP into his Master’s thesis,” stated Anna Lawrence.

“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.

Kongjian Yu pioneered China’s “sponge city” concept—less concrete and more green spaces to exploit stormwater instead of fighting it. Metropolises all over the world are following suit. “Industrialized engineering solutions have messed up the whole water system globally. You have to solve the problem holistically, and the sponge city is a nature-based, holistic solution. It is inexpensive, and it can be done at a small or large scale. You can have your garden, but you also have to plan from the top. It is a sponge planet, it is a sponge countryside, it is a sponge urban district,” stated Konjian Yu.

“What is being done in the upland wilderness affects what goes on in the low land because the source of runoff and sediment that runs through urban areas is in the headwaters,” stated Younes Alila. “Forest hydrologists for over a century swept the dimension of frequency under the carpet in the name of the “public does not understand probability”. The rest is history and it has not turned out well. So, I made the conscious decision to make probability central to my outreach to the media, wider public, professionals, and scientists.”

“And then something happened. We just seemed to lose momentum in the 2010s. With the benefit of hindsight, others have made the same observation. We got bogged down in the implementation plan. We just talked about the burden on local governments from all the capital items that were arising from the completion of integrated stormwater management plans. Coincidentally, this was just as the region’s needs became dominated by transportation, transit, active transportation and cycling. And then we were hit by the pandemic in 2020 and this huge retirement wave,” stated Ray Fung.
