Douglas College Rain Conference

The Water Balance Model:

A Tool for Designing with Nature

slide3

‘Designing with Nature’ means:

  • Create Greener Communities
  • Strive for a Lighter ‘Hydrologic Footprint’
  • Achieve Higher Levels of Stream Protection
slide4

Drainage Planning in BC Has Been Evolving Over the Decades

    • 1960s: Pipe and Remove
    • 1970s: Detain Peak Flows
    • 1980s: Reactive Mitigation
    • 1990s: Stream Stewardship*
    • 2000s: Sharing a Vision**
  • * Proactive Management
  • **Watershed-Based Rainwater Management
slide5

The “Trickle-Down” Evolution of Watershed Management in BC(How the Past is Influencing the Present)

  • 1970s - society’s reaction to the “dam builders”

redefined the engineer’s role, and resulted in an “interdisciplinary and ecosystem approach” to watershed management outside the urban regions

  • 2000s - society’s reaction to the “pipe sizers”

is similarly being translated into an “integrated approach” to urban watershed management at the local government level

inter governmental partnership vision
Inter-Governmental Partnership: Vision
  • To promote changes in land development practices so that:
    • The built environment will preserve and/or restore the natural water balance over time
    • Performance targets will be achieved for rainwater runoff volume and flow rate reduction at the source, where rain falls
slide8

The Mission is to Create a Legacy

  • Influence choices by individuals and organizations
  • Use the term “sustainability” as a lens for considering approaches that influence choices
slide10

The Goal is Full Integration of Philosophy  Tool  StandardsTo Achieve the Desired Outcome

slide11

The Missing Link in Watershed Planning has been...

  • A tool that quantifies the benefits – in terms of reducing rainwater runoff volume - of installing source controls under different land use, soil and climate conditions
slide12

Water Balance Model promotes Integration of Perspectives

  • Planners: Tool for Better Use of Space
  • Engineers: Tool for Pre-Design
  • Landscape Architects:Tool for Green Solutions
  • Ecologists: Tool for Watershed Function
  • Educators: Tool for Social Marketing
slide14

How the Water Balance Model can be used to make better decisions:

  • Local Governments - when communicating with the public
  • Planners and Engineers – when setting performance targets
  • Developers and their Consultants - when testing scenarios
  • Environmental Agencies - when monitoring watershed health
