Green Infrastructure

Green communities – ‘today’s expectations are tomorrow’s standards’ is a provincial government mantra in British Columbia. Since the built and natural environments are connected, design with nature to protect watershed function. The Green Communities Initiative provides a policy, regulatory and program framework for enabling local governments to create more compact, more sustainable and greener communities. Lead by example. Showcase innovation. Celebrate successes.

What is “Green Infrastructure”? – Looking back to understand the origin, meaning and use of the term in British Columbia

“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 Partnership for Water Sustainability in British Columbia is the keeper of the GIP legacy,” observes Paul Ham, a Past-Chair of the Green Infrastructure Partnership

“I see my years of chairing the Green Infrastructure Partnership 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.

URBAN GREEN INFRASTRUCTURE STARTS WITH A RAIN GARDEN: “To scale up our response to climate change requires a concerted, connected and collaborative approach to finding a way to work together towards identifying solutions and taking action. This perspective provides the context for an ecosystem of teaching, interdisciplinary professional practice and research that informs the new Green Infrastructure course,” stated Dr. Joanna Ashworth, Simon Fraser University

“Every significant innovation results from a magical combination of timing, preparation and luck. So true for the creation of a new online course on Green Infrastructure, or GI, at Simon Fraser University. After several years of promoting the use of rain gardens in communities, including offering workshops, my colleagues and I were delighted when the Adaptation Learning Network, awarded funding for us to develop an online course,” stated Joanna Ashworth.

INTEGRATING NATURAL ASSETS INTO INFRASTRUCTURE ON BC’S SUNSHINE COAST: “During construction, we experienced a few 50mm rain events that we had to manage with fire pumps that pumped into the forest, dispersing through sprinklers. Amazingly though, we could see there was no pooling or surface movement. It was our first time seeing in real time what the forest could manage,” stated Michael Wall, Manager of Asset Management & Strategic Initiatives, qathet Regional District

“We received a proposal to manage stormwater using pipes, ditches, and a large sedimentation pond. It was going to cost roughly $850,000 and they were going to clear around a hectare of forest. Jason Gow, senior planner from the City of Powell River, and I went on site to review the proposed engineering design. We wondered why are we clearing a forest to put in infrastructure to manage run-off, when we know the forest can provide that service to some extent? We tried to look for any similar case studies for a “volume of water per area of forest” that can be safely managed, but we could not find anything,” stated Michael Wall.

SEASONAL USE OF WATER IN BALANCE WITH A CHANGING WATER CYCLE: “The City sees the BC Landscape Water Calculator helping us manage our peak demand. I like that the calculator will be able to show people just how much they can reduce their water use,” stated Amy Peters, coordinator of the City of Abbotsford water conservation program

“Many homeowners are now familiar with how much they are using because the number is on their utility bill. It really is important that they be able to see how much outdoor water use contributes to their total water demand. The BC Landscape Water Calculator does this. We are encouraging people to transform their front yards by replacing grass with water efficient plants. We are promoting both water efficient and native plants. The BC Landscape Water Calculator provides them with choices for both,” stated Amy Peters.

“Living Water Smart in British Columbia: Accounting for Stream Systems in Asset Management”, a downloadable version of an article published on Waterbucket eNews about application of the Ecological Accounting Process to the Millstone River in the Regional District of Nanaimo (Vancouver Island), released by the Partnership for Water Sustainability in June 2021

The driver for EAP, the Ecological Accounting Process, is degradation of stream channels and streamside protection areas. “Accounting for our region’s natural assets is part of responsible asset management that includes ecological systems as well as physical infrastructure. This report has given the Regional District of Nanaimo, as well as the City of Nanaimo, further insight as we develop our existing framework for the protection and enhancement of our important natural features in our communities, including stream corridors,” stated Tyler Brown, RDN Chair.

MANAGING THE IMPACTS OF URBANIZATION AND CLIMATE CHANGE: “To scale up our response to climate change requires a concerted, connected and collaborative approach to finding a way to work together towards identifying solutions and taking action,” stated Dr. Joanna Ashworth, Simon Fraser University

“Simon Fraser University has been advancing the implementation of green infrastructure at the municipal level through an interdisciplinary approach combining community-engaged teaching, research and outreach. Building on what we have collectively learned, in 2021 we launched a new 12-week online course. We designed the course to have appeal and applicability for professionals from diverse disciplines, especially those seeking to understand green infrastructure’s potential for managing the impacts of urbanization and climate change,” stated Joanna Ashworth.

FLASHBACK TO 2006: “Vancouver’s Green Streets Program for streetscape enhancement began in 1994 as a pilot project in Vancouver’s Mount Pleasant neighbourhood. The success of the project inspired other neighbourhoods to get involved and liven up their streets,” stated David Desrochers when the City of Vancouver and UBC co-hosted the third event in the pilot program for ‘Showcasing Green Infrastructure Innovation in the Metro Vancouver Region’

David Desrochers is the visionary engineer who provided the driving force for the City of Vancouver’s initiatives in implementing both Country Lanes and Crown Street. “Yes, I am one who pushes the envelope in advocating new ways of building streets and lanes”, admitted Desrochers in 2006, “But I could not have made either Crown Street or Country Lanes happen without the strong support and commitment of Don Brynildsen, the City’s Assistant City Engineer.”

HOW VANCOUVER IS PROTECTING ITSELF FROM FLOODING: “In the old days, it was ‘scoop the water up and send it down these pipes.’ Now, with climate change, we have to restore these old systems,” said Melina Scholefield, the City of Vancouver’s manager of green infrastructure implementation

Vancouver’s narrative over the past two decades has often hinged on densification — how to manage the rise of dull grey towers framed by distant green mountains. But with every megaton of carbon dioxide belched into the atmosphere, the risk of rising seas and increasingly heavy rainfall has pushed the region toward letting more of that forest creep back into the city. Known as “green infrastructure,” the idea is to simulate a natural water cycle wiped out from decades of city building. “We know how to design it,” said Scholefield. “What we’re aimed at now is making it mainstream.”

CREATE SAFE CITIES FOR SALMON: “Inadequate statutory foundations and enforcement of current regulations have only hindered the implementation of nature-based solutions to protect salmon in cities. There must also be increased clarity and communication from the top to ensure these regulatory requirements are understood and effectively implemented,” stated Andrea McDonald, author of the joint research study by the Pacific Water Research Centre and the Salmon-Safe BC team (May 2021)

“Protection of salmon and their habitat from the adverse impacts of urban development is a challenging task that requires an all-of-government response. Findings from this research highlight the variable involvement and guidance provided from the higher levels of government in Canada. As one expert noted, the province must provide more clarity on direct regulatory obligations which have compliance initiatives in place to enforce them,” stated Andrea McDonald. “Providing opportunities for the public to be more engaged and educated on the subject can offer that bottom-up pressure necessary for more rapid-paced change in local governments.”

DOCKSIDE GREEN, WORLD’S GREENEST NEIGHBOURHOOD: “Do we have the intelligence and will to impel change? Can convention be busted open again to develop sustainably? This book encourages sustainable change agents to make fundamental, systemic change. Please go implement. Now,” urges Kim Fowler, author of Dockside Green, the story of the world’s most sustainable development

“At Dockside Green, a ‘sandbox’ development concept was created instead of a ‘straitjacket’ conventional approach. This was achieved by setting the basic requirements for site redevelopment while still providing flexibility to promote innovation and competition in the land sale process. Traditional zoning was deemed to be a ‘straitjacket’ containing far too detailed and prescriptive land use and design. It would have destroyed competition and innovation,” stated Kim Fowler.

DEMONSTRATION APPLICATION OF ECOLOGICAL ACCOUNTING PROCESS: Millstone River in the Regional District of Nanaimo, completed in March 2021

“The EAP methodology reflects the understanding that landowners adjacent to the stream corridor and setback zone and the broader community share responsibility for and benefit from the condition of the stream as well as the financial and ecological value of the land it occupies. The report suggests a general framework for local governments to consider in using the lens of ecological accounting within Corporate Asset Management Plans,” stated Julie Pisani.
