"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," observed Sophie Knight. "A recent survey of global city authorities carried out by the environmental non-profit CDP found 103 cities were at serious risk of flooding. With climate change both a reality and threat, many architects and urbanists are pushing creative initiatives for cities that treat stormwater as a resource, rather than a hazard."
The article provides a concise overview of considerations that have led to integration of two hydrologic models. "The tool underpins 'Beyond the Guidebook: The New Business As Usual (2007)', a provincial initiative to advance implementation of green infrastructure policies and practices throughout British Columbia. The mantra for this provincial initiative is: Today's Expectations are Tomorrow's Standards," stated Paul Ham.
BC's Inter-Governmental Partnership held a Forum in March 2007 so that Partners could share success stories and lessons learned in implementing green infrastructure. “Once the IGP had invited me to be a member of its Expert Advisory Panel, I decided to attend your Water Balance Model Partners Forum because I am very interested in your approach to mitigate environmental impacts associated with urbanization”, Linda Pechacek informed the Partners.
In 2014 the City of Victoria will be rolling out its new Stormwater Utility. "This is something that makes the City of Victoria a leader in Canada. It’s innovative because it encourages people, at the level of their own properties, to take responsibility and leadership for creating solutions – like rain barrels, cisterns, raingardens, bioswales – that are good for the planet and good for the City’s stormwater system," wrote Lisa Helps.
Philadelphia has developed a US$1.6 bllion plan to transform the city over the next 20 years. The plan reimagines the city as an oasis of rain gardens, green roofs, permeable pavements, thousands of additional trees, and more. According to Howard Neukrug, the Philadelphia Water Department’s Director of the Office of Watersheds, "We are taking that (old, grey infrastructure) barrier down, and are stopping the water from ever hitting the system."
“The Vancouver get-together is the first of three cross-Canada working sessions, and will be followed by an event in Calgary later in 2007, with the third event to be held in Toronto in early 2008”, stated Dr. Hans Schreier. Three universities are involved in the project: UBC, Guelph and Waterloo. Three local government organizations are also involved in order to provide a practitioner perspective for each of three participating provinces.
"I read a recent article entitled Stormwater Flooding An Expensive Problem, Hot Issue. Well, it has been an 'expensive' and 'hot' issue for about a hundred years – and our leaders have mostly chosen to ignore that, " wrote Rick Baumann in a guest newspaper column. "We are playing catchup. The result of this brilliant mindset: we end up paying far more to fix a problem further down the road when the absolute need to address it leaves no other option."
"The 21st-century green city is possible. Instead of relying heavily on pipes and concrete, this new approach relies upon soil, trees and open space to naturally absorb, store, evaporate and filter rainwater," says Calvin Sandborn.
"When much of California is facing drought and limited water supplies, capturing and reusing every drop of water will not only be clever, but crucial. By moving water away from the people and places that need it, stormwater cannot percolate into the ground and replenish water we keep drilling deeper and deeper to reach. Californians can counteract the negative impacts of stormwater runoff by promoting water infiltration," wrote Paula Luu.
“Local government plans and policies typically state that land use and infrastructure planning will consider climate change adaptation. Hence, being able to quickly and effectively model how the ‘water balance’ may change over time is a critical input to local government decision processes," stated Chris Jensen."The Climate Change Module supports two provincial initiatives: Living Water Smart; and Preparing for Climate Change: BC’s Adaptation Strategy."
