"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," states Laura Maclean. "The Guidebook approach contrasts with conventional 'flows-and-pipes' stormwater management."
“The Guidebook applied a science-based understanding, developed the water balance methodology to establish performance targets, and demonstrated that urban watershed restoration could be accomplished over a 50-year timeframe as and when communities redevelop,” states Peter Law, Guidebook Chair (2000 - 2002).
"We are using the slogan The New Business As Usual to convey the message that, for change to really occur, practices that until now have been viewed as the exception must become the norm moving forward. We have to build regulatory models and develop models of practice and expertise,” stated Dale Wall, Deputy Minister
Published in March 2002 by the Greater Vancouver Regional District, the "Watershed / Landscape-Based Approach to Community Planning" was developed by an interdisciplinary working group. "At the heart of the approach is an adaptable 10-step methodology that facilitates planning with reference to watershed-based features," reports Erik Karlsen, a primary author of the document.
"Our focus was on the technical details of practices in landscape areas that treat rainwater through plant materials and soils by infiltration, retention, detention and evapotranspiration", states Ed von Euw.
"The premise underpinning the Guidebook was that land development and watershed protection can be compatible. The basis for this premise was that municipalities exert control over runoff volume through their land development and infrastructure policies, practices and actions," states Peter Law.
"A municipality can decide which components are applicable, and can establish the level of effort required based on risk and local conditions. Not all of the components may be relevant for a given watershed or drainage catchment," states Robert Hicks.
The Guidebook formalized a science-based understanding to set performance targets for reducing rainwater runoff volumes and rates. These targets represent the synthesis of biological and hydrological understanding.
