Jim Dumont and Dr. Charles Rowney are the Engineering Applications Authority and Scientific Authority, respectively. The are responsible for constant improving the Water Balance Model to meet the needs of local government.
“By 2002, looking at rainfall differently led the Province of British Columbia to adopt the Water Balance Methodology, initiate a performance target approach to capturing rain where it falls, and initiate changes in the ways rainwater runoff is returned to streams.This science-based approach to rainwater management was formalized in Stormwater Planning: A Guidebook for British Columbia," states Ted van der Gulik.
"The Stormwater Guidebook and Water Balance Model initiatives link directly to land use planning, policy, and regulation. They provide context and a framework for the environmental, economic, social and governance values that shape communities and regions," stated Mayor Barry Janyk.
“The Development Servicing Bylaw provides a relevant frame of reference for implementing the WBM Express. It contains language that clearly identifies that flood risk and erosion be maintained at rates that approximate the natural forested watershed,” observes Steve Ono.
“The drought, forest fires and floods that B.C. experienced in 2003 highlighted the need to integrate ‘green’ development practices with water management. A tool was needed to evaluate and ensure implementation of the best water management practices. The web-based Water Balance Model powered by QUALHYMO is that tool," explains Ted van der Gulik.
"The Water Balance Model, as an approach to managing rainwater, was first introduced in 2003. It was an impressive step towards applying a ‘design with nature’ solution to a growing problem for many municipalities. A ‘new’ WBM was launched at the end of 2008 to considerable acclaim," wrote Kim Stephens in a 2009 article.
