“Part of the problem is not the amount of rain, but how it’s been coming down – not in a steady drizzle, but in intense bursts, as Vancouverites have seen this spring,” wrote Frances Bula.
Look At Rainfall Differently
Recent Development in Washington State: New Map Shows Enormity of Storm Sewer Outfall Problem in Puget Sound
People For Puget Sound have released a map that dramatically shows for the first time all the public stormd rains carrying pollutants into Puget Sound. The map was produced by a team of University of Washington GIS students for People For Puget Sound
Influencing Actions on the Ground in British Columbia: Today's Expectations are Tomorrow's Standards
The Province’s Living Water Smart and Green Communities initiatives provide a framework for convening for action in British Columbia. The ultimate goal is to establish expectatons that will, in turn, influence the form and function of the built environment.
United States National Research Council concludes that EPA Stormwater Program Needs a Significant Overhaul
The U.S. Environmental Protection Agency's stormwater program — which oversees stormwater discharged by cities, industries, and construction activities — needs radical changes if it is to improve the quality of the nation’s waters, says a new report from the National Research Council. It recommends that permits be based on watershed boundaries, and the program focus on the impact of increased water volume rather than chemical pollutants.
Learning Lunch Seminar Series promotes consistent provincial approach to rainwater management and green infrastructure
“The desired outcome is that a common understanding of challenges and solutions will result in consistent expectations at front counters across Vancouver Island. To that end, the purpose of the seminars is to bring together representatives of planning, engineering, operations, building services, environment and parks departments from various municipalities. When developers and development consultants hear a consistent message about what is expected of them, we believe this will further accelerate doing business differently,” stated Kim Stephens.
“Having both tools accessible from the same website provides drainage modellers with a choice, depending on the modelling objectives and the capabilities of the user,” states Ted van der Gulik.
Andy Reese examines how our ideas about stormwater have changed since the 1800s. He insightfully looks back at why we pursued stormwater management in ways which unknowingly – at the time – foreclosed opportunities for more sustainable, livable communities. “It is much easier to know what the next paradigm is than to move into the next paradigm,” wrote Andy Reese.
These sessions deal with computer modelling and the lessons that Jim Dumont has learned over the years. They are intended to provide a foundation of knowledge to those professionals just starting in the field and as a review for more experienced practitioners.
“Fundamental change in the scope of rainwater/stormwater planning, development standards, construction and operations will only happen if there is a broad understanding as to why the changes are needed, what they are, and how they can be practically implemented,” wrote Erik Karlsen. “Publicly-supported decision-makers will determine the timing and phasing of change. The ability of consumers and the development community to adapt will then set the pace of change. Success in one area will be transferred to others.”
The report emphasizes that progressive jurisdictions are developing water balance approaches to rainwater/stormwater management for urban development to mitigate the geomorphic and biotic impacts that result from current practice. Such approaches utilize best management practices to infiltrate or evaporate water and minimize increases in runoff volume.
