Building Forward: How to Properly Construct Low Impact Development Stormwater Management

July 27, 2018 8:30 am to 4:30 pm
TRCA Head Office Waterfront room:  101 Exchange Avenue, Vaughan, ON
Instructors: Kyle Vander Linden and Bill Trenouth

Course description

LID, an innovative stormwater management approach that treats, infiltrates, filters, and retains runoff at the source, is quickly becoming the new norm in Ontario. Construction of LID practices involves techniques and specifications that differ from traditional stormwater management construction practices.

Failing to follow proper LID construction methods can result in barren bioretention landscapes, clogged infiltration practices, uneven permeable pavements, and ultimately costly post construction repairs.

This course is for anyone involved in the design, construction and inspection of LID, whether it is in a large subdivision development or a small parking lot retrofit. Instructors take participants through each step of the LID construction process through to assumption/certification highlighting potential errors and explaining proper techniques.

Participants also receive recommendations for specifications and tender contracts. Experienced instructors will present valuable lessons learned from examples in Ontario and similar cold climate regions.

Items to bring: Scale and calculator

Who should attend?

A course intended for Municipal Staff, Contractors, Landscape Professionals and Consultants.
