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.”

“And isn’t that how turning that supertanker of thinking happens? Just incrementally, then by gosh, we end up going in a whole different direction than we were when we started,” stated Joan Sawicki, Parliamentary Secretary for the Georgia Basin Initiative. Launched in 1994, the GBI was a call to action by the provincial government led by Premier Mike Harcourt. The living legacy of the GBI is embedded in and embodied by the Georgia Basin Inter-Regional Educational Initiative. The IREI is now in Year 13 and provides peer-based education among local governments.

“When I look back at our history, I think wow, how did we do so much applied research. We had a need and Hans Schreier had grad students who were interested in doing the research. Win-win,” stated Richard Boase. “This research was in pursuit of making changes to the fabric of our urbanized areas. I was so encapsulated by what I saw around me, and the need for change, that my mind was always racing. And I needed to find ways to do research into what we were talking about.”

“There are so many different parts to EAP. And with each part you can go down a distinct pathway that helps local governments. I am very focused on the 3-year transition strategy because Year One was just trying to absorb as much knowledge as possible. It was a juggling process with many moving parts and trying to keep them all in balance. But Year One is now behind us. We are envisioning other areas of research as potential EAP projects.. And so, we look forward to sharing our EAP experience at the BC Land Summit,” stated Anna Lawrence.

“By working with the roads people on curb cuts, we have actually come up with variations. Our original detail was quite generic. Now we are able to implement it in various types of curb designs. We are striving to make sure that rain garden maintenance is as easy as possible, including inlets and outlets for drainage. We have evolved the designs so it is EASY CLEAN for all the sediment buildup. Our crews can quickly scoop it with a shovel and be on their way! That change resulted from feedback from engineering operations staff regarding what they wanted to see. We just evolved the design as per their operational needs,” stated Harvy Takhar.

“Drainage is but a sub-set of municipal engineering. Historical engineering practice did not consider some of the broader objectives that we now try to address through green infrastructure. Drainage in the context of urban planning and development decisions has historically been an afterthought,” stated Hugh Fraser. “Delta urban areas are built out. The municipality is effectively limited to retrofitting of rain gardens within road corridors in order to provide rainwater infiltration that protects stream health. Road rights-of-way account for one-third of the land area of a typical urban watershed.”

Susan Haid has played a leadership role in trailblazing an ecosystem-based approach to community planning in British Columbia. “The 1990s was a very instrumental time of policy and regulation development. And municipal dialogue too. The discussions around the Fish Protection Act had a huge influence shifting perspectives to a bigger scale. The course that I teach at UBC is about how policy frameworks shape urban design. Building in resiliency to our cities from the site level to the regional level could NOT be more critical than now,” stated Susan Haid.

“Good decision-making comes down to a good process. But it also relies on wisdom in terms of balanced advice. The essence of my guiding philosophy as a City Manager is distilled into the three Ts which are trust, time and think. Staff gives good advice and Council makes the decisions,” stated Pete Steblin. “When there is a significant level of trust in technical recommendations, Councils rarely override them. Staff explains recommendations. The Council makes the decisions. Trust is fragile and can easily be broken. When trust is lost, decades of good work can be lost.”

“We must do a better job of protecting streams. I am in a position now to reflect on this because I believe I have earned that right over the course of a 30-year career. Given how much I have seen, done and been exposed to in my local government career, it is fair for me to reflect on what has happened and comment on why local governments have not been as successful as we would have wanted. But we must focus on the path forward so that we protect or enhance stream systems in the built environment,” stated Richard Boase.

Langley’s approach to achieving water balance through green Infrastructure evolved as successive neighbourhoods were built over the past two decades. In the beginning, the focus for Green Infrastructure was on what could be achieved within greenways. Langley staff then turned their attention to rain gardens. Building on their history of successes, their next evolution was implementation of “blue links”, which is another name for rain gardens. The blue link is symbolic of the transformational change which has taken root in the Township in the 21st century as designing with nature became the ‘new normal’.

“The term deep knowledge is generally referring to the effective sharing of knowledge that has been informed by a lot of experience. Thus, a work environment that encourages exploring and adapting to new knowledge as well as sharing senior knowledge and learned experience will generate better problem solvers and decisions. A balanced method to form institutional knowledge will draw benefit from the knowledge and experience of senior staff without discounting the contribution of new ideas, approaches, and information,” wrote Bernadette O’Connor.
