Low-impact development (LID) is a holistic approach to stormwater management. This clean-water technology has demonstrated both esthetic and economic benefits; it mimics the natural water cycle to manage stormwater close to where it falls. (See Dr. G. Krantzberg’s “A Valuation of Ecological Services in the Great Lakes Basin Ecosystem to Sustain Healthy Communities and a Dynamic Economy,” prepared for the Ontario Ministry of Natural Resources in 2006).
