The pilot for Beyond the Guidebook is the City of Surrey’s Fergus Creek Watershed Plan. The plan is precedent-setting because there will be no large-scale storage ponds. “Rather, rainwater runoff volume will be managed through constructed facilities and the creation of contiguous large-scale greenways that have been integrated into the area’s land use plan”, stated Remi Dube.

Develop with Care: Environmental Guidelines for Urban and Rural Land Development in British Columbia
“While its primary purpose is to provide province-wide guidelines, Develop with Care also provides information on ways that environmental protection and stewardship can benefit the community, the property owner and the developer, as well as the natural environment,” stated Marlene Caskey.
“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.
Beyond the Guidebook 2007: Context for Rainwater Management and Green Infrastructure in British Columbia
The Guidebook’s premise that land development and watershed protection can be compatible represented a radical shift in thinking in 2002. “Through implementation of ‘green infrastructure’ policies and practices, the desired outcome in going Beyond the Guidebook is to apply what we have learned at the site scale over the past five years…so that we can truly protect and/or restore stream health in urban watersheds”, states Paul Ham,
“Beyond the Guidebook takes the Guidebook innovation to the next level of evolution, Now that practitioners are becoming comfortable with what ‘rainfall capture’ means in practice, local governments and the development community are in a position to turn their attention to what is an achievable outcome that makes sense and results in a net environmental benefit at the watershed scale,” stated Laura Maclean.

“There is a need for a new approach to hydrologic design. A key message is that a rainfall-based approach does not work effectively. This is why I advocate a runoff-based approach. Duration of discharge is important because it links directly to stream health. The ‘runoff-based approach’ holds the key to assessing environmental impacts in watercourses and the effectiveness of mitigation techniques”, stated Jim Dumont.
The ISMP Template provides a standardized process that includes all of the key components for rainwater and stormwater management. These are categorized in terms of three disciplines – engineering, planning and environmental. “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.
In undertaking the Fergus Creek Integrated Stormwater Management Plan, the City of Surrey is pushing the envelope in pioneering the application of innovative approaches that it believes will achieve noticeable benefits over a 50-year planning horizon. The Fergus ISMP “goes beyond the Guidebook” because it is built around a science-based methodology that correlates runoff volume with stream health, reported Paul Ham.
Founded on British Columbia case study experience, 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. Structured to meet the information needs of different audiences, the Guidebook formalized the ‘Integrated Strategy for Managing the Complete Spectrum of Rainfall Events’,
