LID Treatment Train Tool
Lake Simcoe Region Conservation Authority, Toronto and Region Conservation Authority and Credit Valley Conservation have developed a Low Impact Development Treatment Train Tool for use in Ontario. Version 1.0 is scheduled for release this summer, and will be available for download through the Sustainable Technologies Evaluation Program.
The tool will support consideration and realization of Low Impact Development (LID) opportunities for a proposed site plan throughout the design process, undertaken by planners, storm water management designers, and other decision makers for all types of site development or retrofit projects.
Using results from the US Environmental Protection Agency's Storm Water Management Model, the tool will assess runoff volume control targets (retention and captured/treated), along with total suspended solids (TSS) and total phosphorus (TP) reductions for both annual and event-based scenarios, throughout the design process. A preliminary water budget assessment for pre and post conditions is also planned.
Please stay tuned for more updates!
