The document outlines a presentation on Low Impact Development (LID) case studies. It provides details on several LID projects in Ontario, including the objectives and stormwater management strategies employed. The case studies cover a variety of project types, from institutional to commercial to residential developments. Challenges and lessons learned are also discussed, such as the importance of contractor education, maintenance programs, and protecting LID installations during construction.
