In class: Introduction to Low Impact Development (LID)

Tuesday, September 24, 2019

8:30 a.m. - 4:30 p.m.

Holiday Inn & Suites Parkway Conference Centre , St. Catharines, Ontario (View Map)


Low Impact Development (LID) is an innovative stormwater management approach that treats, infiltrates, filters, and retains runoff at the source. LID practices are proven approaches that have been implemented with great success for decades. This approach is quickly gaining traction in Ontario and across Canada as practitioners come to understand the benefits and need for building water resilient communities.

This course will demonstrate how LID differs from traditional stormwater practices, and why it’s becoming a necessary part of our infrastructure. Over the course of the day, participants will learn the fundamentals of LID and review common trends in LID performance. Instructors will also explain how to overcome common barriers to implementing LID including winter performance, site constraints, soils, bedrock, groundwater and utilities.

Participants will have a chance to discuss real world examples of LID projects through a series of case studies on a variety of land use types, including residential, linear and industrial/commercial. These case studies will provide real-world examples where “constraints” have been mitigated through creative planning and design. Instructors will share valuable lessons learned on design, documentation, construction, erosion and sediment control, inspection and maintenance.

Course instructors will also review some of the decision support tools available to help implement LID projects, including the WIKI Design Guide, the LID Treatment Train Tool and the LID Lifecycle Costing Tool.

Who should attend:
This course is intended for developers, consultants, municipal staff, landowners or anyone looking to gain a general knowledge of sustainable stormwater planning and practices.
