LOOK AT RAINFALL DIFFERENTLY: British Columbia’s ‘Beyond the Guidebook Initiative’ introduced at 2007 Annual BCWWA Conference – “To accommodate the requirement to maintain stream health, advances in analysis techniques have led to a system that provides a quantitative analysis of both the potential erosion and the availability of aquatic habitat,” stated Jim Dumont
The key message is that Beyond the Guidebook 2007 was the first guidance document to connects the dots between the Water Balance Methodology and stream health protection. This breakthrough was transformational because it allowed drainage practitioners to develop a watershed approach that addresses stream protection and/or restoration. “We have been able to optimize the designs of mitigation works to both reduce the costs and to increase their effectiveness. In this manner we have gone Beyond the Guidebook in a rational and logical manner to reduce the total system requirements and cost,” stated Jim Dumont.
