Water Balance Express: Restore ‘environmental flows’ in urban streams
The Express helps landowners quantify how well rain gardens on their properties slow, sink and spread runoff. The Express is populated with watershed targets determined by applying the Water Balance Methodology. The flow-duration relationship is the cornerstone of the methodology. “North Vancouver District undertook the ‘proof of concept’ for Express development as an element of its Hastings Creek watershed plan. Other local government leaders have followed. Each time the tool is enhanced,” wrote Richard Boase.
