“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 full benefits of these changes will be realized decades from now.”

“Released in 2002, the Guidebook provides a framework for effective rainwater management throughout the province. This tool for local governments presents a methodology for moving from planning to action that focuses on implementing early action where it is most needed,” stated Laura Maclean. “The Guidebook approach is designed to eliminate the root cause of negative ecological and property impacts of rainwater runoff by addressing the complete spectrum of rainfall events. The Guidebook approach contrasts with conventional ‘flows-and-pipes’ stormwater management.”

The City of Chillwack’s Manual was developed through an inter-departmental and inter-agency process that also included community participation. “Through interaction with the Chilliwack community during its development, the Manual also provided a feedback loop for the Guidebook process. The Manual incorporated the content of the Bylaw that it replaced, and is designed to manage both flood risk and environmental risk,” stated Dipak Basu.
