The proposed research will involve the evaluation of the effects of Low Impact Development (LID) systems onx000D
receiving water systems such as streams, rivers, ponds and lakes. This will be achieved by studying andx000D
comparing newly urbanized or retrofitted communities where stormwater is primarily managed and treatedx000D
through LID systems with communities that possess traditional stormwater systems (curbs and gutters, wetx000D
stormwater management ponds). LID systems have become an increasingly visible infrastructure investmentx000D
throughout Canadian communities as municipalities are faced with the combined effects of aging and costlyx000D
infrastructure, growing urban populations, and increased risks associated with climate change. Despite thex000D
growing demand for LID systems, little is known about the collective influence of LID projects on receivingx000D
waters. Although several studies have explored performance of individual and isolated LID systems, there is ax000D
dearth of information regarding the long-term implications of LID at the neighbourhood or catchment scale.x000D
The immediate effect of this knowledge gap is a tendency to overdesign LID systems and generating costx000D
prohibitive designs. Although research suggests that LID systems provide a net benefit to urban watersheds,x000D
there is no universally accepted means to evaluate their effectiveness at the catchment-level. Within thex000D
stormwater industry there is a growing sense that there is significant room to optimize LID system design tox000D
maximize benefits for urban catchments and receiving waters. There is an opportunity for Canada to become ax000D
driver of innovation in LID technology and the design of stormwater systems.
