FLASHBACK TO 2004: City of Courtenay established a precedent when it was the first BC municipality to adopt and implement a ‘Soil Depth Policy’ for rainwater management
The policy was adopted in January 2004 immediately after the City became a founding member of the Water Balance Model Partnership. The requirement was included in the Official Community Plan. “Because the City places importance on the soil sponge as a rainwater management tool, we explored options to ensure that developers and house builders fulfil their obligations to provide and preserve the minimum required depth,” stated Sandy Pridmore.
FLASHBACK TO 2003: “Home Depot established a BC precedent when it implemented a deep deep-well system for injecting rainwater runoff,” stated Kevin Lagan, formerly Director of Operational Services with the City of Courtenay
“In 2003, the Home Depot development application in the City of Courtenay was to build a store and parking lot covering 90% of a four hectare second growth coniferous forest property,” stated Kevin Lagan. “The City required that post-development rainwater and stormwater flows leaving the site were equal to or less than the pre-development flows. For this property that was effectively zero.”
“A presentation many years ago by Patrick Condon put me on the path to integration. Patrick’s storytelling made me realize that everything we do has an effect somewhere else,” says Ramin Seifi, General Manager, Engineering & Community Development, Township of Langley
“When the previous General Manager of Engineering retired in 2011, our Chief Administrative Officer listened when I presented the case for doing both jobs – Engineering and Community Development,” stated Ramin Seifi. “The Township needed more integration to respond to the demands on infrastructure and the risks to the environment resulting from rapid population growth. Achieving integration depended on the Township having a better structure.”
“Commissioned by the Liuzhou Municipality Urban Planning department, the city will host some 30,000 residents and feature the hallmarks of a typical city, such as offices, houses, hotels, hospitals and schools. These buildings will draw on geothermal energy and rooftop solar panel for their power needs,” wrote Nick Lavars. “Construction is currently underway, with the Liuzhou Forest City expected to be completed by 2020.”
Coping with Heat and Rising Water Levels: “The Pacific Northwest is the best region in the United States for escaping the brunt of climate change,” stated Vivek Shandas, Portland State University
Places with newer infrastructure, with Climate Change Action Plans, that seek to build community across socioeconomic barriers, and are close to rivers or lakes are more likely to be prepared for the worst aspects of climate change. “When evaluating how prepared cities are for climate change, look at a handful of factors, including policy and politics, community organization, and infrastructure,” said Professor Vivek Shandas.
Architect Stefano Boeri is passionate about green infrastructure and demonstrates the art of the possible. “Cities are two per cent of the entire Earth’s land surface, but they are producing 70 per cent of CO2. If we seriously want to deal with climate change, we have to study where climate change is produced. Forests absorb approximately 40 per cent of [man-made] CO2, so increasing the number of trees and plants inside a city is a crucial issue,” comments Stefano Boeri.
100 RESILIENT CITIES: What Would an Entirely Flood-proof City Look Like? – Sophie Knight profiles leaders who are ‘designing with nature’ to lead the way to a water-resilient future (September 2017)
“Along with the explosion of the motorcar in the early 20th century came paved surfaces. Rainwater – instead of being sucked up by plants, evaporating, or filtering through the ground back to rivers and lakes – was suddenly forced to slide over pavements and roads into drains, pipes and sewers," wrote Sophie Knight. "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."
ARTICLE: “Blue Ecology is aligned with the whole-system, water balance vision for restoring ‘Sustainable Watershed Systems, through Asset Management’,” wrote Kim Stephens in an article published in the Asset Management BC Newsletter (September 2017)
“Hydrologists and water managers can help build a brighter future by rediscovering the meaning of water, and interweaving the predominant Western analytical models with the more intuitive indigenous models. Blue Ecology’s philosophy is meant to be the bridge between these two cultural ways of knowing,” stated Michael Blackstock. He developed Blue Ecology, an ecological philosophy that is recognized by UNESCO.
Making Nature Count in the Town of Gibsons – celebrating and showcasing 5 years of leading by example
“Our eco-assets journey began in 2012,” stated Emanuel Machado. “The triggering event was the release of the Gibsons Aquifer Mapping Study. Shortly afterwards the Town changed the definition of infrastructure and formally acknowledged the need to understand and manage (eco)systems and not simply individual infrastructure assets. This action led directly to the Gibsons Eco-Asset Strategy.”
“Sponge Cities” – a catchy way to describe the goal in restoring the capacity of the urban landscape to absorb water and release it naturally
In 2013, President Xi Jinping injected a new term into the global urban design vocabulary when he launched China’s Sponge City program. And then in August 2017, the Senate of Berlin released its Sponge City Strategy. The common guiding philosophy for both? Mimic nature, restore the water balance, adapt to a changing climate. The ‘sponge city’ imagery resonates. People intuitively get it.
